Identifying best practices for increasing HIV pre-exposure prophylaxis (PrEP) use and persistence in the United States: A systematic review
Kamitani E , Higa DH , Crepaz N , Wichser M , Mullins MM . AIDS Behav 2024 A qualitative systematic review was conducted to evaluate pre-exposure prophylaxis (PrEP) interventions, describe characteristics of best practices for increasing PrEP use and persistence, and explore research gaps based on current PrEP interventions. We searched CDC's Prevention Research Synthesis (PRS) Project's cumulative HIV database (includes CINAHL, EMBASE, Global Health, MEDLINE, PsycInfo, and Sociological Abstracts) to identify PrEP intervention studies conducted in the U.S., published between 2000 and 2022 (last searched January 2023). Eligibility criteria include studies that evaluated PrEP interventions for persons testing negative for HIV infection, or for healthcare providers who prescribed PrEP; included comparisons between groups or pre/post; and reported at least one relevant PrEP outcome. Each eligible intervention was evaluated on the quality of study design, implementation, analysis, and strength of evidence (PROSPERO registration number: CRD42021256460). Of the 26 eligible interventions, the majority were focused on men who have sex with men (n = 18) and reported PrEP adherence outcomes (n = 12). Nine interventions met the criteria for Best Practices (i.e., evidence-based interventions, evidence-informed interventions). Five were digital health interventions while two implemented individual counseling, one offered motivational interviewing, and one provided integrated medical care with a PrEP peer navigator. Longer intervention periods may provide more time for intervention exposure to facilitate behavioral change, and engaging the community when developing, designing and implementing interventions may be key for effectiveness. For digital health interventions, two-way messaging may help participants feel supported. Research gaps included a lack of Best Practices for several populations (e.g., Black persons, Hispanic/Latino persons, persons who inject drugs, and women of color) and evidence for various intervention strategies (e.g., interventions for promoting provider's PrEP prescription behavior, peer support). These findings call for more collaborative work with communities to develop interventions that work and implement and disseminate Best Practices for increasing PrEP use and persistence in communities. |
What factors are associated with willingness to use HIV pre-exposure prophylaxis (PrEP) among U.S. Men who have sex with men not on PrEP A systematic review and meta-analysis
Kamitani E , Wichser ME , Mizuno Y , DeLuca JB , Higa DH . J Assoc Nurses AIDS Care 2022 34 (2) 135-145 Pre-exposure prophylaxis (PrEP), an antiretroviral medication to prevent HIV, is becoming more widely available in the United States since the Federal Drug Administration approved it in 2012. However, PrEP use among men who have sex with men (MSM) is still limited and many MSM who are willing to take PrEP are not on PrEP. We performed a systematic review to identify factors associated with willingness to use PrEP among MSM who are not on PrEP. The majority of the 23 relevant studies had low risk of bias and used a cross-sectional design. Willingness was associated with being Hispanic/Latino (odds ratio [OR] = 1.68, 95% confidence interval [CI] [1.01-2.78]), Black (OR = 1.41, 95% CI [1.02-1.95]), younger (OR = 1.08, 95% CI [1.02-1.15]), having no college degree (OR = 1.37, 95% CI [1.12-1.59]), or low income (OR = 1.21, 95% CI [1.12-1.32]). A higher proportion of MSM who had recent condomless anal sex (OR = 1.85, 95% CI [1.49-2.29]) were diagnosed with sexually transmitted infection (OR = 1.60, 95% CI [1.27-2.01]), or MSM who had multiple sex partners (OR = 1.58, 95% CI [1.07-2.32]) were more willing to use PrEP compared with their respective counterparts. Findings suggest that MSM with racial/ethnic minority status, low-socioeconomic status, younger age, and engagement in HIV risk behaviors are willing to take PrEP but may lack access. Study limitations include the inability to conduct meta-analyses on certain predictor variables due to a small number of studies. This review identified MSM subpopulations who may benefit from interventions increasing PrEP access. |
Health care providers' views on clinic infrastructure and practice models that may facilitate HIV preexposure prophylaxis (PrEP) prescribing: A qualitative meta-synthesis
Mizuno Y , Gelaude DJ , Crepaz N , Kamitani E , DeLuca JB , Leighton CA , Wichser ME , Smith DK . Health Promot Pract 2021 23 (6) 999-1014 HIV (human immunodeficiency virus) preexposure prophylaxis (PrEP) is an effective biomedical HIV prevention tool. Increasing PrEP use among populations disproportionately affected by HIV is one of the key efforts in the United States' Ending the HIV Epidemic (EHE) initiative and the HIV National Strategic Plan for the United States. Given that PrEP is available only through prescription, it is important to explore structural, organizational, or environmental factors that could facilitate or impede health care provider's PrEP prescribing behavior. The purpose of this systematic review (PROSPERO [CRD: 42019138889]) is to identify qualitative studies that addressed this topic and conduct meta-synthesis using the thematic synthesis method to identify major themes on the characteristics of clinic infrastructure or clinic models that providers consider as facilitators of PrEP prescribing in the United States. Eighteen citations representing 15 studies were included in this review. Five overarching themes were identified: (1) routinized HIV risk assessment; (2) interdisciplinary/coordinated PrEP teams or services; (3) clinic capacity to provide essential PrEP-related services; (4) low out-of-pocket patient costs; and (5) access to the priority populations. Some of these themes are consistent with the recommendations of CDC's PrEP clinical guidelines and the EHE initiative. More recent studies that include perspectives of diverse providers, timely analysis of these studies, and implementation research to assess strategies to address the current practice gaps are needed to further promote PrEP prescribing among providers in the United States. |
Effectiveness of HIV Stigma Interventions for Men who have Sex with Men (MSM) With and Without HIV in the United States: A Systematic Review and Meta-Analyses
Gunn JKL , Rooks-Peck C , Wichser ME , Denard C , McCree DH , Jeffries WL4th , DeLuca JB , Ross LW , Herron A , Barham T , Flores SA , Higa DH . AIDS Behav 2021 26 51-89 Stigma may contribute to HIV disparities for men who have sex with men (MSM). This systematic review quantified the effects of HIV stigma interventions for MSM on stigma and sex risk. We conducted a systematic search to identify US-based studies published between 2000 and June 2019 focused on HIV and MSM, and either measured stigma pre-post or included a stigma intervention component. Twenty-nine articles, representing 26 unique studies met inclusion criteria. Random effect models showed no intervention effect for reducing stigma and a non-significant increase in HIV testing. Significant decreases in condomless sex with males, condomless sex with females, and substance-influenced sex were found. Few intervention studies measured stigma pre-post. Findings suggest that including a stigma reduction component in interventions can improve HIV testing and reduce sex risk for MSM. Developing interventions to address stigma may be important in decreasing HIV infection among MSM and ending the HIV epidemic. |
Human immunodeficiency virus prevention for people who use drugs: Overview of reviews and the ICOS of PICOS
Johnson WD , Rivadeneira N , Adegbite AH , Neumann MS , Mullins MM , Rooks-Peck C , Wichser ME , McDonald CM , Higa DH , Sipe TA . J Infect Dis 2020 222 S278-s300 BACKGROUND: This article summarizes the results from systematic reviews of human immunodeficiency virus (HIV) prevention interventions for people who use drugs (PWUD). We performed an overview of reviews, meta-analysis, meta-epidemiology, and PROSPERO Registration CRD42017070117. METHODS: We conducted a comprehensive systematic literature search using the Centers for Disease Control and Prevention HIV/AIDS Prevention Research Synthesis Project database to identify quantitative systematic reviews of HIV public heath interventions with PWUD published during 2002-2017. We recombined results of US studies across reviews to quantify effects on HIV infections, continuum of HIV care, sexual risk, and 5 drug-related outcomes (sharing injection equipment, injection frequency, opioid use, general drug use, and participation in drug treatment). We conducted summary meta-analyses separately for reviews of randomized controlled trials (RCTs) and quasi-experiments. We stratified effects by 5 intervention types: behavioral-psychosocial (BPS), syringe service programs (SSP), opioid agonist therapy (OAT), financial and scheduling incentives (FSI), and case management (CM). RESULTS: We identified 16 eligible reviews including >140 US studies with >55 000 participants. Summary effects among US studies were significant and favorable for 4 of 5 outcomes measured under RCT (eg, reduced opioid use; odds ratio [OR] = 0.70, confidence interval [CI] = 0.56-0.89) and all 6 outcomes under quasi-experiments (eg, reduced HIV infection [OR = 0.42, CI = 0.27-0.63]; favorable continuum of HIV care [OR = 0.68, CI = 0.53-0.88]). Each intervention type showed effectiveness on 1-6 outcomes. Heterogeneity was moderate to none for RCT but moderate to high for quasi-experiments. CONCLUSIONS: Behavioral-psychosocial, SSP, OAT, FSI, and CM interventions are effective in reducing risk of HIV and sequelae of injection and other drug use, and they have a continuing role in addressing the opioid crisis and Ending the HIV Epidemic. |
Growth in proportion and disparities of HIV PrEP use among key populations identified in the United States national goals: systematic review & meta-analysis of published surveys
Kamitani E , Johnson WD , Wichser ME , Adegbite AH , Mullins MM , Sipe TA . J Acquir Immune Defic Syndr 2020 84 (4) 379-386 BACKGROUD: PrEP use among populations most vulnerable to HIV as identified in national HIV prevention goals is not fully known. This systematic review assessed trends of lifetime self-reported PrEP use and disparities among key populations. METHODS: We used CDC HIV/AIDS Prevention Research Synthesis cumulative database of electronic and manual searches in MEDLINE, CINAHL, EMBASE, and PsycINFO from 2000-2019 to identify English-language primary studies reporting PrEP use. Two reviewers independently screened citations, extracted data, and assessed risk of bias with modified Newcastle-Ottawa Scale. We estimated pooled proportions and crude/adjusted odds ratios (OR). RESULTS: We identified 95 eligible studies including 95,854 US-based survey respondents. A few studies (6.3%) focused on people who inject drugs (PWID). In 2015-2017, men who have sex with men (MSM) had highest proportion of individuals who used PrEP over their lifetime (13.9%[95%CI:8.8-21.1],k[number of surveys]=49) followed by Hispanic/Latinos (11.5[7.1-18.1],12), transgender women (11.2[5.8-20.6],5), and blacks (9.9[8.3-11.8],18). Odds of PrEP use increased by 34%/year (OR=1.34/year[95%CI:1.09-1.64]) and significantly increased over time among MSM (1.53/year[1.21-1.93]) and blacks (1.44[1.13-1.83]). People in the Southern US (9.9[4.7-19.7],8) and youth (7.3[4.7-11.2],8) had lower rates and did not demonstrate growth (0.94[0.29-3.18];0.82[0.43-1.55]). Odds of reporting lifetime PrEP use was twice (2.07[1.27-3.38]) as great among MSM than non-MSM. CONCLUSIONS: Proportions of PrEP use in published surveys have been growing, but remain low for people in the Southern US and youth, and understudied in PWID. Limitations include few studies in certain years while strengths include large number of respondents. Culturally-tailored approaches targeting vulnerable populations are essential to increase PrEP use to reduce disparities in HIV acquisition. |
Mapping the study characteristics and topics of HIV pre-exposure prophylaxis research literature: A scoping review
Kamitani E , Mizuno Y , Wichser M , Adegbite AH , DeLuca JB , Higa DH . AIDS Educ Prev 2019 31 (6) 505-522 Since WHO released the first PrEP guidance in 2012, the PrEP research literature has rapidly increased, but PrEP uptake is still low. To identify research gaps, this scoping review describes study characteristics, identifies populations, and maps study topics in PrEP publications. We identified 561 PrEP primary studies published in English between 2006 and 2018. The most commonly used study design was cross-sectional. Almost half of studies were conducted in non-U.S. countries and focused on men who have sex with men. We mapped study topics using five categories. The most studied category was Potential PrEP user/prescriber (41.3%) followed by Considerations while on PrEP (28.2%), PrEP efficacy and safety (20.9%), Cost-effectiveness or economic evaluation (5.2%), and Methods of and experiences with PrEP clinical trials (4.2%). Although the PrEP literature has dramatically increased, some research areas (e.g., PrEP awareness in non-U.S. countries, intervention studies to promote PrEP use) and populations (e.g., Black women) are still understudied. |
Analysis of systematic reviews of medication adherence interventions for persons with HIV, 1996-2017
Rooks-Peck CR , Wichser ME , Adegbite AH , DeLuca JB , Barham T , Ross LW , Higa DH , Sipe TA . AIDS Patient Care STDS 2019 33 (12) 528-537 This overview of reviews summarizes the evidence from systematic reviews (SR) on the effectiveness of antiretroviral therapy (ART) adherence interventions for people with HIV (PWH) and descriptively compares adherence interventions among key populations. Relevant articles published during 1996-2017 were identified by comprehensive searches of CDC's HIV/acquired immunodeficiency syndrome (AIDS) Prevention Research Synthesis Database and manual searches. Included SRs examined primary interventions intended to improve ART adherence, focused on PWH, and assessed medication adherence or biologic outcomes (e.g., viral load). We synthesized the qualitative data and used the Assessment of Multiple Systematic Reviews (AMSTAR) for quality assessment. Forty-one SRs met inclusion criteria. Average quality was high. SRs that evaluated text-messaging interventions (n = 9) consistently reported statistically significant improvements in adherence and biologic outcomes. Other ART adherence strategies (e.g., behavioral, directly administered antiretroviral therapy [DAART]) reported improvements, but did not report significant effects for both outcomes, or intervention effects that did not persist postintervention. In the review focused on people who inject drugs (n = 1), DAART alone or in combination with medication-assisted therapy improved both outcomes. In SRs focused on children or adolescents aged <18 years (n = 5), regimen-related and hospital-based DAART improved biologic outcomes. ART adherence interventions (e.g., text-messaging) improved adherence and biologic outcomes; however, results differed for other intervention strategies, populations, and outcomes. Because few SRs reported evidence for populations at high risk (e.g., men who have sex with men), the results are not generalizable to all PWH. Future implementation studies are needed to examine medication adherence interventions in specific populations and address the identified gaps. |
Mapping the study topics and characteristics of HIV pre-exposure prophylaxis research literature: a protocol for a scoping review
Kamitani E , Johnson AH , Wichser M , Mizuno Y , DeLuca JB , Higa DH . BMJ Open 2019 9 (5) e024212 INTRODUCTION: The research literature addressing pre-exposure prophylaxis (PrEP) has increased considerably over the last decade. To better understand the research areas and explore research gaps, we will conduct a scoping review to map study topics and describe study characteristics and populations in publications focused on PrEP. The purpose of this protocol is to describe planned methods for the scoping review. METHODS AND ANALYSIS: We will implement a comprehensive systematic literature search to identify PrEP citations in the United States Centres for Disease Control and Prevention HIV/AIDS Prevention Research Synthesis Project database that is unique and extensively focuses on HIV/sexually transmitted infections/hepatitis. We will screen and include studies that are (1) focused on HIV PrEP, (2) primary research with human participants and (3) published in English. Two reviewers will independently abstract data on authors' names, study years, countries, population characteristics and design. To describe and summarise study topics, we will use 19 codes and five categories that were developed from a preliminary study. The five categories are category 1: potential PrEP user/prescriber (behaviours/issues for potential PrEP takers/healthcare professionals), category 2: considerations while on PrEP (experiences of and problems related to staying on or prescribing PrEP), category 3: PrEP efficacy and safety (biomedical aspects and medication efficacy), category 4: methods of and experiences with PrEP clinical trials (possesses/experiences of clinical trials) and category 5: cost-effectiveness or economic evaluation (cost studies). Data will be analysed with descriptive statistics. ETHICS AND DISSEMINATION: The findings will be presented at HIV-related conferences and published in peer-review journals. |
Increasing prevalence of self-reported HIV pre-exposure prophylaxis (PrEP) use in published surveys - a systematic review and meta-analysis
Kamitani E , Wichser ME , Adegbite AH , Mullins MM , Johnson WD , Crouch PC , Sipe TA . AIDS 2018 32 (17) 2633-2635 When combining results from all published surveys, about one in nine global study participants (10.7%) reported ever using PrEP by 2017, a significant increase since U.S. FDA approval in 2012 (OR = 1.6/year, p < 0.00001). Moreover, nearly one in six US-based study participants (17.3%) and nearly one in four MSM who met the CDC's PrEP indications (24.5%) reported ever using PrEP by 2016. The odds of reporting PrEP use are approximately doubling each year (OR = 1.8/year, p < 0.00001; OR = 2.0/year, p < 0.00001). |
Mental health and retention in HIV care: A systematic review and meta-analysis
Rooks-Peck CR , Adegbite AH , Wichser ME , Ramshaw R , Mullins MM , Higa D , Sipe TA . Health Psychol 2018 37 (6) 574-585 OBJECTIVE: Mental health (MH) diagnoses, which are prevalent among persons living with HIV infection, might be linked to failed retention in HIV care. This review synthesized the quantitative evidence regarding associations between MH diagnoses or symptoms and retention in HIV care, as well as determined if MH service utilization (MHSU) is associated with improved retention in HIV care. METHOD: A comprehensive search of the Centers for Disease Control and Prevention's HIV/AIDS Prevention Research Synthesis database of electronic (e.g., MEDLINE, EMBASE, PsycINFO) and manual searches was conducted to identify relevant studies published during January 2002-August 2017. Effect estimates from individual studies were pooled by using random-effects meta-analysis, and a moderator analysis was conducted. RESULTS: Forty-five studies, involving approximately 57,334 participants in total, met the inclusion criteria: 39 examined MH diagnoses or symptoms, and 14 examined MHSU. Overall, a significant association existed between MH diagnoses or symptoms, and lower odds of being retained in HIV care (odds ratio, OR = 0.94; 95% confidence interval [CI] [0.90, 0.99]). Health insurance status (beta = 0.004; Z = 3.47; p = .001) significantly modified the association between MH diagnoses or symptoms and retention in HIV care. In addition, MHSU was associated with an increased odds of being retained in HIV care (OR = 1.84; 95% CI [1.45, 2.33]). CONCLUSIONS: Results indicate that MH diagnoses or symptoms are a barrier to retention in HIV care and emphasize the importance of providing MH treatment to HIV patients in need.
