This guideline was developed by the New York State Department of Health AIDS Institute (NYSDOH AI) for primary care providers and other practitioners who are initiating therapy in nonpregnant, antiretroviral therapy (ART)-naive adults with HIV. The guideline aims to achieve the following goals:

  • Provide a clear and concise roadmap for clinicians to follow in choosing from among several equally efficacious ART regimens based on individual patient characteristics and preferences.
  • Provide a list of ART regimens to avoid.
  • Provide dosing considerations for individuals with renal or hepatic impairment and important drug-drug and food interactions.
  • Encourage clinicians to seek the assistance of an experienced HIV care provider when treating patients with extensive comorbidities.
  • Integrate current evidence-based clinical recommendations into the healthcare-related implementation strategies of the New York State Ending the Epidemic initiative.

The NYSDOH AI is publishing this guideline at a critical time: 1) prompt initiation of ART is now recommended for all individuals diagnosed with HIV; 2) identifying and linking individuals with HIV to care and treatment that achieves optimal virologic suppression are crucial to the success of the New York State Ending the Epidemic initiative; and 3) the ability of primary care providers and other clinicians in New York State to properly select initial ART is key to the successful treatment of individuals with HIV.

Introduction: The NYSDOH AI Medical Care Criteria Committee recommendations for prescribing ART regimens for treatment-naive, nonpregnant adults (age ≥18 years) with HIV-1 and without acquired resistance are based on a comprehensive review of available clinical trial data. (For guidelines specific to treatment of adolescents with HIV, please consult the DHHS Guidelines for the Use of Antiretroviral Agents in Adults and Adolescents Living with HIV). In formulating its recommendations for New York State, this committee balanced the strength of published evidence regarding efficacy of treatment regimens with factors that influence adherence, including pill burden, tolerability, and dosing schedule. Preferred regimens are supported by evidence and have favorable adherence profiles, with lower pill burdens, fewer adverse effects, and dosing schedules that may be easier for individuals to manage. Ranking of regimens in this manner is designed to inform discussion and decision-making with patients.

How to use this guideline: Tables presenting preferred and alternative regimens appear first (see guideline section Available ART Regimens). To help guide the choice among regimens of similar efficacy, each table includes comments that address selected pertinent issues regarding each regimen, such as limitations based on a patient’s kidney function and drug-drug interactions.

Other sections of the guideline include a review of relevant issues, patient considerations, essential laboratory assessments, and the rationale for the recommendations. Reference to the expanded information is crucial for addressing factors that may be of particular importance when individualizing a patient’s treatment, such as loss of bone mineral density with a regimen that includes tenofovir disoproxil fumarate and the conflicting data on cardiac risk with abacavir (see guideline section Specific Factors to Consider and Discuss With Patients). In addition, a review of psychosocial factors and individual patient preferences may help in the selection of an initial ART regimen. Importantly, a patient-centered approach that incorporates both clinical and nonclinical issues should be prioritized.

Scope: This guideline addresses initial treatment of HIV-1 infection with ART in nonpregnant adults.

Note on “experienced” and “expert” HIV care providers: Throughout this guideline, when reference is made to “experienced HIV care provider” or “expert HIV care provider,” those terms are referring to the following 2017 NYSDOH AI definitions:

  • Experienced HIV care provider: Practitioners who have been accorded HIV Experienced Provider status by the American Academy of HIV Medicine or have met the HIV Medicine Association’s definition of an experienced provider are eligible for designation as an HIV Experienced Provider in New York State. Nurse practitioners and licensed midwives who provide clinical care to individuals with HIV in collaboration with a physician may be considered HIV Experienced Providers as long as all other practice agreements are met (8 NYCRR 79-5:1; 10 NYCRR 85.36; 8 NYCRR 139-6900). Physician assistants who provide clinical care to individuals with HIV under the supervision of an HIV Specialist physician may also be considered HIV Experienced Providers (10 NYCRR 94.2)
  • Expert HIV care provider: A provider with extensive experience in the management of complex patients with HIV.

RECOMMENDATIONS
Regimen Selection
  • When selecting an initial ART regimen for treatment naive-patients, clinicians should:
    • Perform genotypic HIV resistance testing results for protease (A2), reverse transcriptase (A2), and integrase (B2) genotypic resistance if the testing has not already been performed or results are not otherwise available.
    • Inform patients of the regimen options and engage in shared decision-making to optimize the likelihood of adherence. (A3)
    • Assess for comorbidities and chronic coadministered medications that may affect the choice of regimen for a patient’s initial ART. (A3)
    • Choose a preferred ART regimen unless one of the alternative regimens is a better choice based on individual patient factors. (A1)
    • Recommend a single-tablet regimen or a regimen with once-daily dosing unless those regimens are contraindicated by HIV resistance, drug-drug interactions, intolerance, allergy, or access. (A2)
    • Ask patients about their reproductive plans [a] and discuss the use of contraception. (A3)
  • With the exception of DTG/3TC, clinicians should not prescribe 2-drug regimens as initial ART. (A3) Clinicians should prescribe DTG/3TC only after:
    • HIV resistance and HBV status are known. (A1)
    • Genotypic resistance testing results have confirmed that a patient does not have a major reverse transcriptase mutation, including the M184V/I resistance mutation. DTG/3TC is contraindicated in patients with these resistance-associated mutations. (A1)
Expert Consultation
  • Clinicians should consult with an experienced HIV care provider when selecting an initial ART regimen for a patient who has:
    • Baseline genotypic testing results indicating the need for an ART regimen other than the available preferred or alternative regimens. (A3)
    • Extensive comorbidities, including metabolic complications and obesity; comedications; impaired renal function; HBV or hepatitis C virus coinfection; or active opportunistic infections. (B3)
    • The NYSDOH Clinical Education Initiative provides access to HIV specialists through their toll-free line: 1-866-637-2342.
Follow-up
  • Clinicians or clinical support staff should follow up by telephone or other methods, preferably within 2 weeks after treatment initiation, to assess tolerance and adherence; adherence should be reinforced at regular intervals. (A3)
  • Clinicians should obtain a viral load test within 4 weeks after ART initiation to assess initial response to therapy. (A3)

Note: 

  1. In choosing an initial ART regimen for a patient who is pregnant or planning a pregnancy, refer to DHHS Recommendations for the Use of Antiretroviral Drugs During Pregnancy and Interventions to Reduce Perinatal HIV Transmission in the United States.

Available Antiretroviral Agents and Regimens

An initial ART regimen should be selected on the basis of patient preferences and clinical characteristics, and a preferred regimen should be used whenever possible. Each of the preferred, alternative, and other initial ART regimens for nonpregnant adults is expected to produce full viral suppression; however, the regimens differ in tolerability, possible toxicities, convenience, and the potential for drug-drug interactions, all of which can affect overall adherence and, therefore, suppression rates.

Preferred backbone: This committee recommends that either formulation of tenofovir (TAF or TDF) can be used as part of the backbone in preferred regimens. A recent meta-analysis of 14 clinical trials Pilkington, et al. 2020, comparing the efficacy and safety of TAF versus TDF in boosted and unboosted subgroups, found comparable efficacy and safety profiles with the use of unboosted TDF compared with TAF (see Table 1, below). Studies have shown that TDF-related renal toxicity is more common when using TDF in a regimen containing COBI or RTV Pilkington, et al. 2020Hill, et al. 2018Cuzin, et al. 2017Ryom, et al. 2013Goicoechea, et al. 2008. Therefore, this committee does not recommend TDF use with boosted regimens when initiating therapy.

In a study of ART-naive individuals, RAL HD 1200 mg once daily was noninferior to 400 mg tablets dosed twice daily and is thus preferred Cahn(b), et al. 2017.

Greater weight gain has also been observed after initiation of TAF or with a switch from TDF to TAF, especially in conjunction with INSTIs Łomiak, et al. 2021Surial, et al. 2021Bourgi(a), et al. 2020Bourgi(b), et al. 2020Calmy, et al. 2020Lake, et al. 2020Sax, et al. 2020Venter, et al. 2020Venter, et al. 2019. However, the predictors, mechanisms of actions, and clinical significance of these findings is unknown.

Third drug: An INSTI as the third drug is preferred over PIs and NNRTIs based on tolerability and a lower incidence of drug-drug interactions. RPV is not appropriate for patients with a viral load >100,000 copies/mL or CD4 count ≤200 cells/mm3 and is contraindicated with PPIs. TAF/FTC/RPV is included as an alternative regimen.

EFV-containing regimens, although efficacious, have been shown to be less well tolerated than the preferred or alternative regimens.

LPV/RTV-containing regimens are no longer included among the options for initial treatment because of pill burden and reduced tolerability in comparison with other boosted PIs.

When initiating ART at the time of HIV diagnosis (i.e., “rapid start” or “test and treat”), avoid regimens containing ABC unless the result of HLA-B*5701 testing is known to be negative.

Single-Tablet Regimens Versus Multi-Tablet Regimens

The advantages of STRs compared with MTRs include simplicity, convenience, and lower risk of selective nonadherence Gardner, et al. 2008. A recent meta-analysis demonstrated that STRs had better adherence rates when compared with MTRs of any frequency (once daily or twice daily) and had higher 48-week viral suppression rates with comparable adverse effects Clay, et al. 2015.

In another retrospective study, INSTI-based regimens generally had greater rates of suppression and a lower probability of viral rebound after suppression in comparison to NNRTI-based regimens, regardless of whether an STR or MTR was used, but STR INSTI-based therapy was more durable Mills(b), et al. 2016. In the same study, STR NNRTI-based therapy led to greater rates of suppression than MTR NNRTI-based therapy Mills(b), et al. 2016.

Notes:

  1. Consider safety, cost, and access when choosing between use of TDF/FTC or TAF/FTC.
  2. Refer to DHHS Recommendations for the Use of Antiretroviral Drugs During Pregnancy and Interventions to Reduce Perinatal HIV Transmission in the United States.
  3. TDF and TAF are approved by the FDA as treatment for HBV. FTC is also active against HBV but is not FDA-approved for HBV treatment. TDF or TAF in combination with FTC or 3TC, which is FDA-approved for HBV treatment and is molecularly similar to FTC, is commonly used in patients with HIV/HBV coinfection as part of an antiretroviral regimen to treat both infections.
Table 1: Important Clinical Considerations With Either TDF/FTC or TAF/FTC as Initial ART [a]
If the patient is at risk of chronic kidney disease (e.g., age >40 years, with hypertension, diabetes, or preexisting mild kidney disease): The greater possibility of kidney disease among individuals who have risk factors is an essential component of the risk-benefit discussion and shared decision-making regarding initiation of tenofovir-containing regimens.

If the patient has osteopenia, osteomalacia, or osteoporosis:

  • The risk of bone loss in individuals with preexisting risk factors or documented osteopenia, osteomalacia, or osteoporosis is an important component of the risk-benefit discussion and shared decision-making regarding initiation of TDF/FTC or TAF/FTC.
  • TDF is associated with osteomalacia and decreases in bone mineral density McComsey, et al. 2011Stellbrink, et al. 2010Perrot, et al. 2009.
  • TAF/FTC is preferred for people with osteoporosis.

If the patient has concerns about weight gain, hyperlipidemia, or metabolic disorders:

If the patient is an adolescent or youth:

  • There is limited data on bone safety in adolescents taking TAF/FTC. However, given the more favorable bone biomarkers of TAF versus TDF, TAF may have an advantage in adolescents who have not achieved bone maturation. Because this advantage is theoretical and not currently supported with clinical data, a clear recommendation cannot be made at this time.

If the patient is pregnant or attempting to conceive:

  • Information about the potential benefits and risks of taking tenofovir-containing regimens during pregnancy is an essential component of shared decision-making regarding risk reduction.
  • Due to the greater experience with TDF in this population, TDF/FTC is the preferred dual NRTI backbone for use as HIV treatment during pregnancy [b].
  • Prospectively report information regarding use of ART medications during pregnancy to the Antiretroviral Pregnancy Registry.

If the patient has active chronic HBV:

  • TDF, TAF, and FTC are active against HBV. TDF and TAF are considered equally effective against HBV [c].
  • Discontinuation of TDF/FTC or TAF/FTC in patients with chronic HBV requires close monitoring for rebound HBV viremia.

Other studies have demonstrated better efficacy and adherence, lower cost to patients, and fewer hospital admissions associated with STRs than with MTRs Griffith, et al. 2019Mills(b), et al. 2016Armstrong, et al. 2015Maggiolo, et al. 2015Hanna, et al. 2014Nachega, et al. 2014Sweet, et al. 2014Cohen(a), et al. 2013Colombo, et al. 2013Raboud, et al. 2011Bangalore, et al. 2007.

There are 3 STRs listed below as preferred regimens. It is possible that these regimens may contain 1 or more components that are not appropriate for an individual patient, do not allow for adjustment of individual components for renal function, have significant drug-drug interactions, are poorly tolerated, or may be more expensive than the individual components prescribed separately, particularly if available as generic formulations. With full adherence, any of the preferred or alternative regimens should lead to full suppression. This includes MTRs, which can be used when an STR is not possible or not tolerated. Cost and access may also be determinative factors.

For patients with impaired baseline renal function, separating the drugs into individual components and adjusting each may be appropriate (see guideline section ARV Dose Adjustments for Hepatic or Renal Impairment).

Table 2 includes initial ART regimens preferred by this committee; Table 3 lists alternative initial regimens. Table 4 lists other available ART regimens that this committee considers neither preferred nor alternative. Within each table, regimens are listed alphabetically. For specific details on choosing a regimen, see the discussions in other sections of this guideline and/or the package inserts for the drugs listed below.

USE OF DOLUTEGRAVIR IN INDIVIDUALS OF CHILDBEARING CAPACITY

Reviewed and updated: Geoffrey A. Weinberg, MD, with the Medical Care Criteria Committee; May 2021

Evidence from multiple studies indicates no difference in rates of total birth defects among infants exposed to antiretroviral (ARV) medications during the first trimester compared with infants exposed later in pregnancy. ARVs are generally considered safe and may be taken by pregnant patients with HIV without increasing the risk of infant birth defects. The MCCC is providing the following updated information for medical care providers concerning preliminary reports that previously had linked dolutegravir (DTG) to neural tube defects (NTDs) in infants exposed to dolutegravir during the periconception period [Zash, et al. 2022]. Read the full statement.

Goals of ART: The issue of when to start ART was settled with the publication of the START and TEMPRANO studies early in 2015 Danel, et al. 2015Lundgren, et al. 2015. Treatment is now recommended for all individuals with confirmed HIV regardless of CD4 cell count or viral load.

The goal of ART is complete and durable suppression of plasma viremia while minimizing toxicity and maximizing quality of life. Properly selected ART may never require a change or adjustment once started. Treatment interruptions should be avoided El-Sadr, et al. 2006.

Since the approval of ZDV on March 19, 1987, there have been 30 individual agents approved for the treatment of HIV and 1 pharmacokinetic enhancer or “booster,” COBI, which is currently used to enhance the pharmacokinetics of EVG, ATV, or DRV. RTV at treatment doses is poorly tolerated and is used only at lower doses for pharmacokinetic boosting of PIs. An additional 18 FDA-approved FDCs are also available. These FDCs include STRs, of which there are 9 currently available that provide a complete and effective treatment regimen for HIV that is combined into 1 pill for use in properly selected individuals. The goal of initial therapy is to start a regimen that suits an individual’s lifestyle and is appropriate given existing baseline medical comorbidities (see Table 5, below).

Active drugs from 2 different classes: Although regimen options for treatment-naive, nonpregnant adults are constantly evolving, the same general principles that were established with the first effective and durable therapies are still true today Gulick, et al. 2000. The backbone of therapy has traditionally been 2 NRTIs paired with 1 of the following: an NNRTI, a boosted PI, or a boosted or unboosted INSTI. In a large meta-analysis, INSTIs were superior to other drug classes as a third drug Lee, et al. 2014, and DTG may have specific advantages because of the lack, to date, of documented resistance developing in ART-naive patients who initiate DTG-containing regimens Wainberg and Mesplede 2015. The entry inhibitors and fusion inhibitors are not recommended for initial therapy (see Table 6: Selected Drug-Drug Interactions to Discuss Before Initiating ART in Treatment-Naive Patients), but they may have a role in ART for treatment-experienced patients with extensive drug resistance (see All FDA-Approved HIV Medications, including generic and trade names).

The only 2-drug regimen that this committee recommends for ART initiation is DTG/3TC, although other dual- and even monotherapy regimens have been and continue to be studied Cahn, et al. 2020Cahn, et al. 2019Baril, et al. 2016Cahn(a), et al. 2017Maggiolo, et al. 2016Bedimo, et al. 2014Cahn, et al. 2014Raffi, et al. 2014Taiwo, et al. 2011. Importantly, use of DTG/3TC is recommended only after the result of HIV resistance and HBV testing are known. Further, this committee recommends against the use of DTG/3TC in patients with major NRTI resistance, including the M184V/I mutation.

If DTG/3TC is started in a patient with HBV infection, a third antiviral agent with activity against HBV should be added. Because the Gemini 1 and 2 studies restricted entry to patients with HIV-1 RNA ≤500,000 copies/mL, this committee recommends against use of DTG/3TC in patients with HIV-1 RNA >500,000 copies/mL.

TAF, a prodrug formulation for tenofovir, was developed as an alternative to TDF and has been approved as part of the following STRs:

Oral administration of TAF results in lower circulating levels of tenofovir in plasma and affects markers of renal toxicity and bone mineral density less adversely than does TDF Mills(a), et al. 2016Pozniak, et al. 2016Sax, et al. 2015. Bioequivalence studies in healthy volunteers show that the TAF 10 mg dose administered with COBI 150 mg is equivalent to the TAF 25 mg dose without COBI Zack(a), et al. 2016Zack(b), et al. 2016.

A switch study showed good maintenance of viral suppression when changing from TDF/FTC to TAF 10 mg/FTC if the third drug was a boosted PI, or to TAF 25 mg/FTC if the third drug was an unboosted NNRTI or INSTI Gallant, et al. 2016. Note that TAF 10 mg alone and TAF 10 mg/FTC are not currently FDA-approved.

Until further safety data are available, this committee has not included TAF 25 mg/FTC in combination with COBI or RTV as recommended regimens and recommends caution when using TAF 25 mg/FTC with regimens that contain either COBI or RTV in the setting of CrCl <50 mL/min.

COBI-boosted DRV was approved based on bioavailability studies FDA(d) 2016Kakuda, et al. 2014. DRV/COBI has demonstrated comparable efficacy to RTV-boosted DRV in a single-arm study Tashima, et al. 2014. However, because randomized clinical trials that compare COBI- versus RTV-boosted DRV are not yet available, it has a lower strength of evidence rating. COBI-boosted ATV showed noninferiority when compared with RTV-boosted ATV with a TDF/FTC backbone in a randomized, double-blind study Gallant, et al. 2013.

KEY POINT
  • INSTI-based regimens are generally the best choice for most individuals because of tolerability and durability.

All of the currently recommended preferred regimens have similar virologic efficacy when measured by an “on-treatment” metric, but adherence, the potential for drug interactions, and tolerability under real-life conditions may inform the choice of preferred versus alternative versus other regimens.

The following general conclusions can be drawn based on currently available evidence from a number of pivotal studies:

The recommended ART regimens should work well for the majority of patients, but some circumstances may make 1 regimen more favorable than another for a given individual. In general, an INSTI-based regimen will be the best option for most patients Mills(b), et al. 2016Lee, et al. 2014. To date, no resistance has been reported in ART-naive patients treated with DTG as part of a registrational trial of combination therapy, suggesting that this medication may be an excellent choice, particularly given its tolerability and lack of drug-drug interactions Cevik, et al. 2020Wainberg and Mesplede 2015. Regimens containing a boosted PI or DTG may be more appropriate when adherence is a concern, given the higher barrier to resistance. For patients with acute symptomatic infection or advanced HIV with an opportunistic infection, some experts would use both DTG and boosted DRV together with the NRTI backbone given the possibility of transmitted NRTI resistance until genotypic information is available, at which time the regimen can be adjusted. Consultation with an experienced HIV care provider is recommended when choosing a regimen for patients with extensive comorbidities, impaired renal function, HBV or HCV coinfection, or very high viral loads.

Early clinical trials in HIV used surrogate markers, such as viral load and CD4 cell count, or clinical endpoints, such as morbidity and mortality, to demonstrate superiority of new therapies over the “gold standard” treatment of the era. One of the trials that led to the 1996 approval of IDV compared IDV alone versus ZDV/3TC versus ZDV/3TC/IDV in ZDV- treatment-experienced patients, given that, at the time, dual NRTI treatment was considered acceptable Gulick, et al. 1997.

As treatment has evolved and become more effective, the use of clinical end points has become challenging; most trials in the current era of HIV therapy are powered to detect noninferiority when compared with standard of care. For a variety of reasons, including cost and complexity, it would be impractical to conduct head-to-head comparisons of all available regimens. Some STRs and FDCs have been approved primarily based on bioequivalence studies when compared with the individual components, such as TDF/FTC/EFV, ABC/3TC/DTG, TAF/FTC/RPV, TAF/FTC, and DRV/COBI.

Some of the cutoff values used for comparisons, such as viral load <100,000 copies/mL or CD4 count ≥200 cells/mm3, are somewhat arbitrary. For example, most studies including RPV show that its efficacy is diminished when initiated at viral loads ≥100,000 copies/mL, and 1 study showed that RPV worked less well than EFV-based therapy at a viral load of ≥500,000 copies/mL Domingo and Ribera 2013.

Some agents have been approved based on noninferiority to the relatively less well-tolerated TDF/FTC/EFV regimen, which is, nevertheless, a potent and effective regimen for those who tolerate it well. The higher prevalence of NNRTI resistance mutations when transmitted drug resistance occurs has prompted most experts to avoid NNRTI-based regimens if treatment is indicated before genotypic resistance testing results are available Panichsillapakit, et al. 2016Rhee, et al. 2015Stekler, et al. 2015. Although coformulated TAF/FTC/COBI/EVG is approved for use at any starting viral load, reports of failure using TDF/FTC/COBI/EVG, with resistance, have been documented in individuals with very high baseline viral loads >1,000,000 copies/mL Adams, et al. 2016Rhee, et al. 2015.

A paucity of data is available demonstrating how different antiretroviral medications perform based on race and gender, although studies have suggested, for instance, that DRV/RTV is less well tolerated in women than in men and that discontinuation of DRV/RTV occurs at a higher rate among Black patients than among others Smith, et al. 2012Currier, et al. 2010.

Long-acting injectable therapy: An injectable long-acting formulation of the INSTI CAB and the NNRTI RPV (CAB/RPV LA) has been approved by the FDA as replacement ART for adults and adolescents ≥12 years old who FDA 2021:

  • Weigh ≥35 kg
  • Do not have chronic hepatitis B virus infection
  • Are virally suppressed (HIV-1 RNA level <50 copies/mL) on a stable ART regimen
  • Have no history of treatment failure
  • Have no known or suspected resistance to either CAB or RPV

Although not FDA-approved as initial ART or for individuals with detectable viremia, the use of CAB/RPV LA as replacement ART in virally suppressed patients engaged in care may be a suitable option for those who would prefer an alternative to daily oral therapy.

Before initiating ART, the following factors are important to consider and discuss with patients.

Age: As individuals with HIV age, they have a higher prevalence of comorbidities than younger patients with HIV and are likely to be on more non–HIV-specific medications, particularly cardiovascular or gastrointestinal agents, posing a higher risk for adverse interactions Marzolini, et al. 2011. For individuals older than 50 years, careful regimen selection, with the use of INSTIs when possible rather than cytochrome P450 inhibitors, such as COBI or RTV, can help minimize interactions. And use of TAF rather than TDF can lower the risk of renal and bone toxicity.

Comorbidities: Assessment for existing cardiovascular risk, renal disease or risk factors for the development of renal disease, hepatic disease, bone health, mental health, and substance use should be performed. Additionally, the risk for greater weight gain and potential exacerbation of metabolic complications with TAF- versus TDF-containing regimens, especially when combined with certain INSTI-based regimens, should be discussed prior to initiation of ART.

Cost: STRs may be favorable because of the lower copays that could be associated with fewer prescriptions. Conversely, the individual components of these regimens may be available generically as separate pills.

Dosing requirements (daily vs. twice daily): Most patients express a preference for once-daily dosing, especially if they are not taking other medications or are taking other medications that are dosed once daily. If individuals are already taking other medications that are dosed twice daily and report no adherence issues, twice-daily dosing is an acceptable option.

Drug-drug interactions: Because of some key drug-drug interactions, coadministration of some medications is to be avoided (see Table 6, below). For instance, PPIs should not be coadministered with oral RPV; however, injectable RPV can be used with PPIs. Given the availability of over-the-counter PPIs and the possibility that these drugs may be prescribed by a different care provider, this interaction is especially important to discuss with patients. In this case, to avoid unnecessary regimen changes once started, even patients who are not currently taking a PPIs should be asked whether they have needed PPIs in the past or may need them in the future. Dose limitations for metformin may also be required when combined with DTG and possibly BIC.

RTV and COBI have many significant and important interactions, including with cardiac medications. Methadone maintenance requirements may also change with some antiretroviral agents. A detailed review of all of a patient’s medications, including over-the-counter medications or supplements, is essential.

Before prescribing an ART regimen, using an automated interaction checker embedded in the electronic medical record or tools such as the following to check for potential drug-drug interactions with currently prescribed medications can help avoid serious problems:

Drugs ARV(s): Comments
H2-blockers
  • ATV: In treatment-naive patients on boosted ATV, H2-blockers should be taken simultaneously with ATV/RTV with food. If simultaneous dosing with food is not possible, ATV/RTV should be taken at least 10 hours after the H2-blocker. H2-blocker doses should not exceed the equivalent of 40 mg famotidine twice daily for ART-naive patients or 20 mg famotidine twice daily for ART-experienced patients.
  • RPV: Use with caution; administer H2-blockers at least 12 hours before or at least 4 hours after RPV.
  • Inhaled steroids
  • Statins
  • COBI; RTV: Alternatives or dose adjustments may be needed.
  • Consult the package inserts for drug-drug interactions between specific statins and ARVs.
Polyvalent cations [a]
  • BIC; DTG: Take 2 hours before or 6 hours after DTG; calcium-containing antacids or iron supplements may be taken simultaneously if taken with food.
  • RAL: Magnesium- or aluminum-containing antacids are contraindicated; calcium-containing antacids are acceptable.
  • RAL HD: Magnesium- or aluminum-containing antacids are contraindicated; coadministration of calcium-containing antacids is not recommended.
  • EVG: Separate dosing by 2 hours, either before or after dose of EVG.
PPIs
  • ATV: Contraindicated with ATV in treatment-experienced patients; in treatment-naive patients, use no more than equivalent of 20 mg of omeprazole with ATV, separated by 12 hours.
  • RPV: Contraindicated.
Metformin
  • DTG: Metformin levels are significantly raised when coadministered with DTG. If used concomitantly, total daily dose of metformin should not exceed 1,000 mg without clinical evaluation of efficacy and adverse events.
Ethinyl estradiol and norethindrone [b]
  • ATV/COBI; DRV/COBI; DRV/RTV; EFV: Use alternative or additional (e.g., barrier) contraceptive methods or choose alternative ART regimen.
  • ATV; ATV/RTV: Use with caution; see manufacturer’s package insert for specific dosing information.
Factor Xa inhibitors
  • COBI; RTV:
    • Apixaban: Reduce dose by 50% if patient is on 5 mg twice daily; avoid use if the indicated dose is 2.5 mg twice daily (based on age, weight, creatinine level).
    • Dabigatran: No adjustment needed if CrCl ≥50 mL/min; avoid if CrCl <50 mL/min.
    • Rivaroxaban: Avoid use.
Platelet inhibitors
  • COBI; RTV:
    • Clopidogrel: Avoid use.
    • Prasugrel: No adjustment needed.
    • Ticagrelor: Avoid use.

Food requirements: Because an individual may have a strong preference for taking medication with or without food, it is important to discuss which medications must be taken on an empty stomach, which must be taken with food, and which can be taken with or without food, as listed in Box 1, below.

Number of pills: Some patients feel strongly that the fewer the number of pills, the better. For others, the greatest concern may be the ability to take all pills (regardless of the number) together once daily. Sometimes using individual agents rather than a multi-agent FDC or STR may be attractive depending on pill size. In rare cases, individuals who either cannot or will not swallow pills may need liquid formulations or pill crushing. Table 7, below, presents an abbreviated summary of commonly used ARVs and their availability in liquid formulation and/or the acceptability of crushing or dissolving them prior to ingestion.

Pill size: Use images or real examples to give patients an idea of pill size before they fill the prescription. TAF/FTC/BIC and TAF/FTC/RPV are the smallest STR pills.

Pregnancy or conception planning: Individuals of childbearing potential should receive a pregnancy test and be assessed for use of contraception. When selecting an initial regimen for those who are not using effective contraception or who are contemplating pregnancy, clinicians should consult DHHS Recommendations for the Use of Antiretroviral Drugs During Pregnancy and Interventions to Reduce Perinatal HIV Transmission in the United States.

All patients should be assessed for conception plans, which also provides an opportunity to discuss PrEP for partners without HIV. Additionally, all individuals with HIV should be informed that maintaining a plasma HIV RNA level <200 copies/mL with ART prevents sexual transmission of HIV to their partners.

Bone disease: TDF causes a decrease in bone mineral density in all patients after initiation of ART and should be used with caution in patients with preexisting severe osteoporosis McComsey, et al. 2011Stellbrink, et al. 2010Perrot, et al. 2009. Some experts recommend baseline bone densitometry screening for osteoporosis in postmenopausal women and in men and transgender women older than 50 years who have HIV Aberg, et al. 2014. The TAF formulation available currently in TAF/FTC, TAF/FTC/EVG/COBI, TAF/FTC/BIC, and TAF/FTC/RPV is an alternative, with lower markers of bone turnover in clinical trials Bonora, et al. 2016Pozniak, et al. 2016.

Cardiovascular risks: COBI- or RTV-containing regimens typically elevate lipids; TAF and certain INSTIs can cause greater weight gain than other ART regimens, with the potential for increased risk of metabolic complications Łomiak, et al. 2021Surial, et al. 2021Bourgi(a), et al. 2020Bourgi(b), et al. 2020Calmy, et al. 2020Lake, et al. 2020Sax, et al. 2020Venter, et al. 2020Venter, et al. 2019. TDF-containing regimens can have a beneficial effect on lipids Souza, et al. 2013. ABC has been associated with a higher risk of myocardial infarction in some studies Marcus, et al. 2016Choi, et al. 2011Obel, et al. 2010Sabin, et al. 2008SMART/INSIGHT and D:A:D Study Groups 2008, whereas other studies have not confirmed this association Ding, et al. 2012Bedimo, et al. 2011Ribaudo, et al. 2011Brothers, et al. 2009. Based on the available data, ABC should be used with caution in patients with multiple cardiac risk factors or known coronary heart disease; however, the absolute risk of myocardial infarction remains low, and no clear causality has been established. In the appropriate clinical circumstance, such as for a patient with impaired renal function, the use of ABC would be acceptable Llibre and Hill 2016. Clinicians should be made aware of the conflicting study data and share this information with patients.

Liver disease: In patients with existing liver disease of any etiology, dose adjustment of ARVs may be required depending on the severity of hepatic impairment (see guideline section ARV Dose Adjustments for Hepatic or Renal Impairment).

Mental health and substance use: Factors that may influence adherence should be addressed. There are also potential interactions between illicit (e.g., methamphetamine) and licit substances (e.g., methadone) and ARVs Kumar, et al. 2015.

KEY POINT
  • Neither mental health nor substance use disorders are contraindications to initiating ART. In some special cases, delay of initiation (for as short a time as possible) may be appropriate while addressing adherence issues and possible interactions.

Renal function: TDF can cause renal tubular dysfunction, such as acquired Fanconi syndrome Zimmermann, et al. 2006Karras, et al. 2003. The risk of renal impairment has been shown to be elevated in patients with preexisting renal disease, longer treatment duration, low body weight, and when used in conjunction with RTV- or COBI-boosted regimens Mocroft, et al. 2016Gervasoni, et al. 2013. In general, full-dose TDF should be used with caution in patients with baseline CrCl <70 mL/min and should be adjusted or changed to an alternative agent if CrCl decreases to <50 mL/min; TAF is a better choice in these patients. As noted above, TAF 25 mg/FTC should be used with caution in boosted regimens when CrCl is <50 mL/min.

Both ATV/RTV and LPV/RTV have also been independently associated with a greater decrease in renal function over time than NNRTI-based regimens Quesada, et al. 2015Goicoechea, et al. 2008. COBI, and to a lesser extent DTG, can inhibit the excretion of creatinine, with expected elevations of creatinine at initiation of therapy. However, such increases are not clinically relevant and do not significantly affect glomerular filtration rate Lepist, et al. 2014Koteff, et al. 2013German(a), et al. 2012.

Although DTG is highly bound to plasma proteins and is unlikely to be removed by dialysis, it has not been studied in this population FDA 2013; therefore, RAL or a boosted PI with renally adjusted 3TC and either ABC or once-weekly TDF are usually the regimens of choice in this population.

Additional information on prescribing agents for patients with reduced renal function is available in the guideline section ARV Dose Adjustments for Hepatic or Renal Impairment.

Very high viral load (HIV RNA level >750,000 copies/mL): In some cases, experts will recommend use of both boosted DRV and DTG in addition to 2 NRTIs when a patient’s viral load is very high, with possible simplification once viral suppression is achieved. Numerous switch studies have demonstrated the safety of simplifying ARV regimens in virally suppressed individuals with no preexisting drug resistance Cazanave, et al. 2015Arribas, et al. 2014Mills, et al. 2013Fisher, et al. 2009. Consultation with an experienced HIV care provider in these situations is helpful.

KEY POINTS
  • Both COBI and DTG can cause decreased tubular excretion of creatinine and may cause a slight increase in measured creatinine.
  • ABC has been associated with a higher risk of myocardial infarction in some studies, although not in others. No clear causal link has been established.
  • Boosted PIs and COBI-boosted EVG are associated with a higher incidence of hyperlipidemia than unboosted INSTIs.
  • Consultation with an experienced HIV care provider is advised when a patient’s baseline viral load is very high (HIV RNA level >750,000 copies/mL).

  • ABC: abacavir
  • ATV: atazanavir
  • BIC: bictegravir
  • COBI: cobicistat
  • DOR: doravirine

  • ARV: antiretroviral
  • CDC: Centers for Disease Control and Prevention
  • CrCl: creatinine clearance
  • FDC: fixed-dose combination
  • HBV: hepatitis B virus
  • HCV: hepatitis C virus
  • INSTI: integrase strand transfer inhibitor
  • NRTI: nucleoside/nucleotide reverse transcriptase inhibitor
  • NNRTI: non-nucleoside reverse transcriptase inhibitor
  • PI: protease inhibitor
  • STR: single-tablet regimen
  • TB: tuberculosis

Baseline CD4 cell count: Some regimens should not be used when the CD4 count is <200 cells/mm3 because of an increased risk of treatment failure (see Table 8, below). When Pneumocystis jiroveci pneumonia prophylaxis is indicated, it may be prudent to defer ART for 7 to 10 days if 2 medications that may cause rash will be started, such as TMP-SMX and EFV.

Baseline HIV genotypic resistance profile: Genotypic resistance testing that includes the protease, reverse transcriptase, and integrase genes should be obtained at diagnosis (or initial visit if not done previously), but ART initiation should not be delayed pending the results Kuritzkes, et al. 2008Borroto-Esoda, et al. 2007.

Transmitted integrase resistance was identified in 0.7% of genotypic resistance tests obtained within 3 months of HIV diagnosis from 2013 to2017 in New York State Wang, et al. 2019. Similarly, 0.8% of baseline genotypic resistance tests across 23 U.S. jurisdictions of the CDC reported INSTI resistance, which had a higher prevalence (1.6%) in metropolitan areas (population 50,000 to 500,000) McClung, et al. 2022. Although INSTI resistance overall remains rare, most experts believe that transmission of INSTI resistance will increase over time, given that this class of ARV has become the preferred therapy for ART initiation (including rapid ART initiation) in all major guidelines.

Consultation with a care provider experienced in ART management is warranted when patients have baseline resistance that requires treatment with a regimen other than the listed preferred or alternative regimens. If treatment is indicated before genotypic resistance testing results are available, NNRTI-based regimens should be avoided because of the higher prevalence of transmitted resistance in NNRTIs than in PIs or INSTIs Panichsillapakit, et al. 2016Rhee, et al. 2015Stekler, et al. 2015. In the case of, for example, a patient with symptomatic acute HIV or advanced HIV with an opportunistic infection, some experts would include a second-generation INSTI (DTG or BIC or boosted DRV, or both together) with the NRTI backbone, given the possibility of transmitted NRTI resistance, with possible simplification once genotypic information is available.

Baseline viral load: Some regimens should not be used when the HIV RNA level is ≥100,000 copies/mL (see Table 8, below, and comments in the tables of preferred and alternative ART regimens).

Coinfections: Patients should be assessed for chronic HBV, HCV coinfection, and TB. The ART regimen for individuals with chronic HBV should treat both HIV and HBV when possible. For those planning concurrent HCV treatment or treatment for active TB, drug-drug interactions will play an important role in the selection of a regimen. The University of Liverpool HEP Drug Interactions Checker is a useful resource for identifying drug-drug interactions.

Creatinine clearance level: Some ARVs are contraindicated below a given CrCl level, and some may need adjustments that require the use of individual elements of an FDC or STR rather than the single-tablet version of the drug (see guideline section ARV Dose Adjustments for Hepatic or Renal Impairment).

Hepatic profile: Some ARVs require dose adjustment in the presence of impaired liver function; patients with abnormal liver enzyme levels or evidence of decreased synthetic function should be assessed for underlying liver disease (see guideline sections Special Considerations for Comorbid Conditions and ARV Dose Adjustments for Hepatic or Renal Impairment).

KEY POINTS
  • When initiating ART at the time of HIV diagnosis (“rapid start”), it is not necessary to have the results of baseline laboratory tests immediately available. Laboratory tests, as indicated below, should be ordered at the time of initiation of ART, and any necessary adjustments to therapy should be made as soon as the results are available (such as for renal function or evidence of resistance).
  • ABC-containing regimens should not be used for rapid start without a documented negative HLA-B*5701 test result.

HLA-B*5701 testing: To avoid potentially serious or life-threatening hypersensitivity reactions, HLA-B*5701 testing is mandatory before initiating ART that includes ABC Mallal, et al. 2008Saag, et al. 2008.

Initiation of the regimens listed in Table 8, below, is contraindicated based on the listed baseline laboratory parameters.

All Recommendations

ALL RECOMMENDATIONS: SELECTING AN INITIAL ART REGIMEN
Regimen Selection
  • When selecting an initial ART regimen for treatment naive-patients, clinicians should:
    • Perform genotypic HIV resistance testing results for protease (A2), reverse transcriptase (A2), and integrase (B2) genotypic resistance if the testing has not already been performed or results are not otherwise available.
    • Inform patients of the regimen options and engage in shared decision-making to optimize the likelihood of adherence. (A3)
    • Assess for comorbidities and chronic coadministered medications that may affect the choice of regimen for a patient’s initial ART. (A3)
    • Choose a preferred ART regimen unless one of the alternative regimens is a better choice based on individual patient factors. (A1)
    • Recommend a single-tablet regimen or a regimen with once-daily dosing unless those regimens are contraindicated by HIV resistance, drug-drug interactions, intolerance, allergy, or access. (A2)
    • Ask patients about their reproductive plans [a] and discuss the use of contraception. (A3)
  • With the exception of DTG/3TC, clinicians should not prescribe 2-drug regimens as initial ART. (A3) Clinicians should prescribe DTG/3TC only after:
    • HIV resistance and HBV status are known. (A1)
    • Genotypic resistance testing results have confirmed that a patient does not have a major reverse transcriptase mutation, including the M184V/I resistance mutation. DTG/3TC is contraindicated in patients with these resistance-associated mutations. (A1)
Expert Consultation
  • Clinicians should consult with an experienced HIV care provider when selecting an initial ART regimen for a patient who has:
    • Baseline genotypic testing results indicating the need for an ART regimen other than the available preferred or alternative regimens. (A3)
    • Extensive comorbidities, including metabolic complications and obesity; comedications; impaired renal function; HBV or hepatitis C virus coinfection; or active opportunistic infections. (B3)
    • The NYSDOH Clinical Education Initiative provides access to HIV specialists through their toll-free line: 1-866-637-2342.
Follow-up
  • Clinicians or clinical support staff should follow up by telephone or other methods, preferably within 2 weeks after treatment initiation, to assess tolerance and adherence; adherence should be reinforced at regular intervals. (A3)
  • Clinicians should obtain a viral load test within 4 weeks after ART initiation to assess initial response to therapy. (A3)

Rationale

Throughout its guidelines, the New York State Department of Health (NYSDOH) AIDS Institute (AI) Clinical Guidelines Program recommends “shared decision-making,” an individualized process central to patient-centered care. With shared decision-making, clinicians and patients engage in meaningful dialogue to arrive at an informed, collaborative decision about a patient’s health, care, and treatment planning. The approach to shared decision-making described here applies to recommendations included in all program guidelines. The included elements are drawn from a comprehensive review of multiple sources and similar  attempts to define shared decision-making, including the Institute of Medicine’s original description [Institute of Medicine 2001]. For more information, a variety of informative resources and suggested readings are included at the end of the discussion.

Benefits

The benefits to patients that have been associated with a shared decision-making approach include:

  • Decreased anxiety [Niburski, et al. 2020; Stalnikowicz and Brezis 2020]
  • Increased trust in clinicians [Acree, et al. 2020; Groot, et al. 2020; Stalnikowicz and Brezis 2020]
  • Improved engagement in preventive care [McNulty, et al. 2022; Scalia, et al. 2022; Bertakis and Azari 2011]
  • Improved treatment adherence, clinical outcomes, and satisfaction with care [Crawford, et al. 2021; Bertakis and Azari 2011; Robinson, et al. 2008]
  • Increased knowledge, confidence, empowerment, and self-efficacy [Chen, et al. 2021; Coronado-Vázquez, et al. 2020; Niburski, et al. 2020]

Approach

Collaborative care: Shared decision-making is an approach to healthcare delivery that respects a patient’s autonomy in responding to a clinician’s recommendations and facilitates dynamic, personalized, and collaborative care. Through this process, a clinician engages a patient in an open and respectful dialogue to elicit the patient’s knowledge, experience, healthcare goals, daily routine, lifestyle, support system, cultural and personal identity, and attitudes toward behavior, treatment, and risk. With this information and the clinician’s clinical expertise, the patient and clinician can collaborate to identify, evaluate, and choose from among available healthcare options [Coulter and Collins 2011]. This process emphasizes the importance of a patient’s values, preferences, needs, social context, and lived experience in evaluating the known benefits, risks, and limitations of a clinician’s recommendations for screening, prevention, treatment, and follow-up. As a result, shared decision-making also respects a patient’s autonomy, agency, and capacity in defining and managing their healthcare goals. Building a clinician-patient relationship rooted in shared decision-making can help clinicians engage in productive discussions with patients whose decisions may not align with optimal health outcomes. Fostering open and honest dialogue to understand a patient’s motivations while suspending judgment to reduce harm and explore alternatives is particularly vital when a patient chooses to engage in practices that may exacerbate or complicate health conditions [Halperin, et al. 2007].

Options: Implicit in the shared decision-making process is the recognition that the “right” healthcare decisions are those made by informed patients and clinicians working toward patient-centered and defined healthcare goals. When multiple options are available, shared decision-making encourages thoughtful discussion of the potential benefits and potential harms of all options, which may include doing nothing or waiting. This approach also acknowledges that efficacy may not be the most important factor in a patient’s preferences and choices [Sewell, et al. 2021].

Clinician awareness: The collaborative process of shared decision-making is enhanced by a clinician’s ability to demonstrate empathic interest in the patient, avoid stigmatizing language, employ cultural humility, recognize systemic barriers to equitable outcomes, and practice strategies of self-awareness and mitigation against implicit personal biases [Parish, et al. 2019].

Caveats: It is important for clinicians to recognize and be sensitive to the inherent power and influence they maintain throughout their interactions with patients. A clinician’s identity and community affiliations may influence their ability to navigate the shared decision-making process and develop a therapeutic alliance with the patient and may affect the treatment plan [KFF 2023; Greenwood, et al. 2020]. Furthermore, institutional policy and regional legislation, such as requirements for parental consent for gender-affirming care for transgender people or insurance coverage for sexual health care, may infringe upon a patient’s ability to access preventive- or treatment-related care [Sewell, et al. 2021].

Health equity: Adapting a shared decision-making approach that supports diverse populations is necessary to achieve more equitable and inclusive health outcomes [Castaneda-Guarderas, et al. 2016]. For instance, clinicians may need to incorporate cultural- and community-specific considerations into discussions with women, gender-diverse individuals, and young people concerning their sexual behaviors, fertility intentions, and pregnancy or lactation status. Shared decision-making offers an opportunity to build trust among marginalized and disenfranchised communities by validating their symptoms, values, and lived experience. Furthermore, it can allow for improved consistency in patient screening and assessment of prevention options and treatment plans, which can reduce the influence of social constructs and implicit bias [Castaneda-Guarderas, et al. 2016].

Clinician bias has been associated with health disparities and can have profoundly negative effects [FitzGerald and Hurst 2017; Hall, et al. 2015]. It is often challenging for clinicians to recognize and set aside personal biases and to address biases with peers and colleagues. Consciously or unconsciously, negative or stigmatizing assumptions are often made about patient characteristics, such as race, ethnicity, gender, sexual orientation, mental health, and substance use [Avery, et al. 2019; van Boekel, et al. 2013; Livingston, et al. 2012]. With its emphasis on eliciting patient information, a shared decision-making approach encourages clinicians to inquire about patients’ lived experiences rather than making assumptions and to recognize the influence of that experience in healthcare decision-making.

Stigma: Stigma may prevent individuals from seeking or receiving treatment and harm reduction services [Tsai, et al. 2019]. Among people with HIV, stigma and medical mistrust remain significant barriers to healthcare utilization, HIV diagnosis, and medication adherence and can affect disease outcomes [Turan, et al. 2017; Chambers, et al. 2015], and stigma among clinicians against people who use substances has been well-documented [Stone, et al. 2021; Tsai, et al. 2019; van Boekel, et al. 2013]. Sexual and reproductive health, including strategies to prevent HIV transmission, acquisition, and progression, may be subject to stigma, bias, social influence, and violence.

SHARED DECISION-MAKING IN HIV CARE
  • As prevention and treatment modalities in HIV care expand (i.e., vaccines, barriers, injectables, implants, on-demand therapies), it is important for clinicians to ask patients about their goals for prevention and treatment rather than assume that efficacy is the primary factor in patient preference [Sewell, et al. 2021].
  • The shared decision-making approach to clinical care enhances patient knowledge and uptake of new technologies and behavioral practices that align with the patient’s unique preferences and identity [Sewell, et al. 2021], ensures that the selection of a care plan is mutually agreed upon, and considers the patient’s ability to effectively use and adhere to the selected course of prevention or treatment.

Guideline Development and Recommendation Ratings

Guideline Development: New York State Department of Health AIDS Institute Clinical Guidelines Program
Program manager Clinical Guidelines Program, Johns Hopkins University School of Medicine, Division of Infectious Diseases. See Program Leadership and Staff.
Mission To produce and disseminate evidence-based, state-of-the-art clinical practice guidelines that establish uniform standards of care for practitioners who provide prevention or treatment of HIV, viral hepatitis, other sexually transmitted infections, and substance use disorders for adults throughout New York State in the wide array of settings in which those services are delivered.
Expert committees The NYSDOH AI Medical Director invites and appoints committees of clinical and public health experts from throughout New York State to ensure that the guidelines are practical, immediately applicable, and meet the needs of care providers and stakeholders in all major regions of New York State, all relevant clinical practice settings, key New York State agencies, and community service organizations.
Committee structure
  • Leadership: AI-appointed chair, vice chair(s), chair emeritus, clinical specialist(s), JHU Guidelines Program Director, AI Medical Director, AI Clinical Consultant, AVAC community advisor
  • Contributing members
  • Guideline writing groups: Lead author, coauthors if applicable, and all committee leaders
Disclosure and management of conflicts of interest
  • Annual disclosure of financial relationships with commercial entities for the 12 months prior and upcoming is required of all individuals who work with the guidelines program, and includes disclosure for partners or spouses and primary professional affiliation.
  • The NYSDOH AI assesses all reported financial relationships to determine the potential for undue influence on guideline recommendations and, when indicated, denies participation in the program or formulates a plan to manage potential conflicts. Disclosures are listed for each committee member.
Evidence collection and review
  • Literature search and review strategy is defined by the guideline lead author based on the defined scope of a new guideline or update.
  • A comprehensive literature search and review is conducted for a new guideline or an extensive update using PubMed, other pertinent databases of peer-reviewed literature, and relevant conference abstracts to establish the evidence base for guideline recommendations.
  • A targeted search and review to identify recently published evidence is conducted for guidelines published within the previous 3 years.
  • Title, abstract, and article reviews are performed by the lead author. The JHU editorial team collates evidence and creates and maintains an evidence table for each guideline.
Recommendation development
  • The lead author drafts recommendations to address the defined scope of the guideline based on available published data.
  • Writing group members review the draft recommendations and evidence and deliberate to revise, refine, and reach consensus on all recommendations.
  • When published data are not available, support for a recommendation may be based on the committee’s expert opinion.
  • The writing group assigns a 2-part rating to each recommendation to indicate the strength of the recommendation and quality of the supporting evidence. The group reviews the evidence, deliberates, and may revise recommendations when required to reach consensus.
Review and approval process
  • Following writing group approval, draft guidelines are reviewed by all contributors, program liaisons, and a volunteer reviewer from the AI Community Advisory Committee.
  • Recommendations must be approved by two-thirds of the full committee. If necessary to achieve consensus, the full committee is invited to deliberate, review the evidence, and revise recommendations.
  • Final approval by the committee chair and the NYSDOH AI Medical Director is required for publication.
External reviews
  • External review of each guideline is invited at the developer’s discretion.
  • External reviewers recognized for their experience and expertise review guidelines for accuracy, balance, clarity, and practicality and provide feedback.
Update process
  • JHU editorial staff ensure that each guideline is reviewed and determined to be current upon the 3-year anniversary of publication; guidelines that provide clinical recommendations in rapidly changing areas of practice may be reviewed annually. Published literature is surveilled to identify new evidence that may prompt changes to existing recommendations or development of new recommendations.
  • If changes in the standard of care, newly published studies, new drug approval, new drug-related warning, or a public health emergency indicate the need for immediate change to published guidelines, committee leadership will make recommendations and immediate updates and will invite full committee review as indicated.
Recommendation Ratings Scheme
Strength Quality of Evidence
Rating Definition Rating Definition
A Strong 1 Based on published results of at least 1 randomized clinical trial with clinical outcomes or validated laboratory endpoints.
B Moderate * Based on either a self-evident conclusion; conclusive, published, in vitro data; or well-established practice that cannot be tested because ethics would preclude a clinical trial.
C Optional 2 Based on published results of at least 1 well-designed, nonrandomized clinical trial or observational cohort study with long-term clinical outcomes.
2† Extrapolated from published results of well-designed studies (including nonrandomized clinical trials) conducted in populations other than those specifically addressed by a recommendation. The source(s) of the extrapolated evidence and the rationale for the extrapolation are provided in the guideline text. One example would be results of studies conducted predominantly in a subpopulation (e.g., one gender) that the committee determines to be generalizable to the population under consideration in the guideline.
3 Based on committee expert opinion, with rationale provided in the guideline text.
