Identifying Best Practices for Increasing HIV Pre-exposure Prophylaxis (PrEP) Use and Persistence in the United States: A Systematic Review.

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.

A Community Guide Systematic Review: Digital HIV Pre-Exposure Prophylaxis Interventions.

INTRODUCTION: HIV preexposure prophylaxis (PrEP) is highly effective when taken as prescribed. Digital health adherence interventions have been identified as effective for improving antiretroviral therapy adherence among people with HIV, but limited evidence exists for PrEP adherence interventions among people without HIV. The purpose of this Community Guide systematic review was to present the characteristics and effectiveness of digital PrEP adherence interventions. METHODS: The author searched the CDC HIV Prevention Research Synthesis cumulative database for digital health interventions with PrEP adherence outcomes published in peer-reviewed journals from 2000 to 2022. Studies with comparison arms or pre-post data evaluating interventions in high-income countries were included. Two reviewers independently screened citations, extracted data, conducted risk of bias assessment, and resolved discrepancies through discussion. Summary effect estimates were calculated using median and interquartile interval. RESULTS: Nine studies were included and all focused on gay, bisexual, and other men who have sex with men. Eight studies were U.S.-based while the other was conducted in the Netherlands. Five were randomized control trials and four were pre-/post studies. All studies showed improved adherence in the intervention arms compared with comparison groups or preintervention data. One study also reported improvement in PrEP care retention. DISCUSSION: Digital health adherence interventions with different strategies to improve PrEP and HIV-related outcomes were identified. The small number of studies identified is a limitation. Findings from this review served as the basis for the Community Preventive Services Task Force recommendation to use these interventions to increase PrEP adherence to prevent HIV infection.

Systematic Review of Social Determinants of Health Associated With HIV Testing Among Hispanic/Latino Gay, Bisexual, and Other Men Who Have Sex With Men in the United States.

This systematic review synthesized published literature (January 2008-October 2021) about the association between social determinants of health (SDOH) and HIV testing among Hispanic/Latino gay, bisexual, and other men who have sex with men (HLMSM), a group disproportionally affected by HIV. Having higher education than a high school diploma, health insurance and access to health care services, and visiting a health care provider in the past 12 months were some of the determinants associated with HIV testing, while limited English proficiency was associated with reduced odds of HIV-testing among HLMSM. More research is needed to understand the relationship of SDOH (especially neighborhood) and HIV testing, how SDOH may affect HIV testing among different HLMSM groups, and how to increase self-testing and use of e-health in this priority population. Additionally, culturally and linguistically appropriate multilevel interventions and health services for HLMSM are urgently needed to diagnose HIV as early as possible after infection.

Strategies to improve HIV care outcomes for people with HIV who are out of care.

OBJECTIVE: The aim of this study was to evaluate the effectiveness of five intervention strategies: patient navigation, appointment help/alerts, psychosocial support, transportation/appointment accompaniment, and data-to-care on HIV care outcomes among persons with HIV (PWH) who are out of care (OOC). DESIGN: A systematic review with meta-analysis. METHODS: We searched CDC's Prevention Research Synthesis (PRS) Project's cumulative HIV database to identify intervention studies conducted in the U.S., published between 2000 and 2020 that included comparisons between groups or prepost, and reported at least one relevant outcome (i.e. re-engagement or retention in HIV care, and viral suppression). Effect sizes were meta-analyzed using random-effect models to assess intervention effectiveness. RESULTS: Thirty-nine studies reporting on 42 unique interventions met the inclusion criteria. Overall, intervention strategies are effective in improving re-engagement in care [odds ratio (OR) = 1.79;95% confidence interval (95% CI): 1.36-2.36, k = 14], retention in care (OR = 2.01; 95% CI: 1.64-2.64, k = 22), and viral suppression (OR = 2.50;95% CI: 1.87-3.34, k = 27). Patient navigation, appointment help/alerts, psychosocial support, and transportation/appointment accompaniment improved all three HIV care outcomes. Data-to-care improved re-engagement and retention but had insufficient evidence for viral suppression. CONCLUSION: Several strategies are effective for improving HIV care outcomes among PWH who are OOC. More work is still needed for consistent definitions of OOC and HIV care outcomes, better reporting of intervention and cost data, and identifying how best to implement and scale-up effective strategies to engage and retain OOC PWH in care and reach the ending the HIV epidemic goals.

Research Synthesis, HIV Prevention Response, and Public Health: CDC's HIV/AIDS Prevention Research Synthesis Project.

OBJECTIVE: Research synthesis, through qualitative or quantitative systematic reviews, allows for integrating results of primary research to improve public health. We examined more than 2 decades of work in HIV prevention by the Centers for Disease Control and Prevention's (CDC's) HIV/AIDS Prevention Research Synthesis (PRS) Project. We describe the context and contributions of research synthesis, including systematic reviews and meta-analyses, through the experience of the PRS Project. METHODS: We reviewed PRS Project publications and products and summarized PRS contributions from 1996 to July 2020 in 4 areas: synthesis of interventions and epidemiologic studies, synthesis methods, prevention programs, and prevention policy. RESULTS: PRS Project publications summarized risk behaviors and effects of prevention interventions (eg, changing one's perception of risk, teaching condom negotiation skills) across populations at risk for HIV infection and intervention approaches (eg, one-on-one or group meetings) as the HIV/AIDS epidemic and science evolved. We used the PRS Project cumulative database and intervention efficacy reviews to contribute to prevention programs and policies through identification of evidence-based interventions and development of program guidance. Subject matter experts and scientific evidence informed PRS Project products and contributions, which were implemented through strategic programmatic partnerships. CONCLUSIONS: The contributions of the PRS Project to HIV prevention and public health efforts in the United States can be credited to CDC's long-standing support of the project and its context within a federal prevention agency, where HIV programs and policies were developed and implemented. The effect of the PRS Project was likely facilitated by opportunities to directly influence program and policy because of connections with other research translation activities and program and policy decision making within CDC.

HIV care outcomes among transgender persons with HIV infection in the United States, 2006-2021.

OBJECTIVES: HIV prevalence is an estimated 14% among transgender women (TW) and 3% among transgender men (TM). HIV care is vital for viral suppression but is hindered by transphobia and HIV stigma. We assessed HIV care outcomes among transgender persons (TG) with HIV in the United States. DESIGN: Systematic review and meta-analysis of peer-reviewed journal articles. METHODS: We searched multiple electronic databases and Centers for Disease Control and Prevention's HIV Prevention Research Synthesis database for 2006-September 2020. Eligible reports were US-based studies that included TG and reported HIV care outcomes. Random-effects models were used to calculate HIV care outcome rates. The protocol is registered with PROSPERO (CRD42018079564). RESULTS: Few studies reported outcomes for TM; therefore, only TW meta-analysis results are reported. Fifty studies were identified having low-to-medium risk-of-bias scores. Among TW with HIV, 82% had ever received HIV care; 72% were receiving care, and 83% of those were retained in HIV care. Sixty-two percent were currently virally suppressed. Among those receiving HIV care or antiretroviral therapy (ART), 67% were virally suppressed at last test. Sixty-five percent were linked to HIV care 3 months or less after diagnosis. Seventy-one percent had ever been prescribed ART. Approximately 66% were taking ART, and 66% were ART-adherent. Only 56% were currently adherent the previous year. CONCLUSIONS: HIV care outcomes for TW were not ideal, and research gaps exists for TM. High heterogeneity was observed; therefore, caution should be taken interpreting the findings. Integrating transgender-specific health needs are needed to improve outcomes of transgender persons across the HIV care continuum.

A Rapid Review of Disparities in HIV Prevention and Care Outcomes Among Hispanic/Latino Men Who Have Sex With Men in the United States.

In the United States, Hispanic/Latino men who have sex with men (HLMSM) are disproportionally affected by HIV. We conducted a rapid review of national surveillance data to examine disparities in HIV prevention and care outcomes among HLMSM. Thirteen reports provided relevant data from 2011 to 2018. Compared to White MSM, a higher percentage of HIV-negative HLMSM reported not taking PrEP and engaging in condomless sex; a lower percentage of HIV-negative HLMSM at risk for HIV reported PrEP awareness and use; and a lower percentage of HIV-positive HLMSM were aware of their status, linked to HIV care, and virally suppressed. Viral suppression rates in HLMSM were better among Ryan White clients than the national rates, suggesting that access to comprehensive care/services reduces disparities. Findings also call for identifying individual, social, and structural factors contributing to condomless sex without PrEP use and HIV status unawareness and identifying best approaches for scaling up comprehensive care/services.

Human Immunodeficiency Virus Prevention for People Who Use Drugs: Overview of Reviews and the ICOS of PICOS.

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 and Meta-analysis of Published Surveys.

BACKGROUND: Pre-exposure prophylaxis (PrEP) use among populations most vulnerable to HIV as identified in the 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 the CDC HIV/AIDS Prevention Research Synthesis cumulative database of electronic and manual searches in MEDLINE, CINAHL, EMBASE, and PsycINFO from 2000 to 2019 to identify English-language primary studies reporting PrEP use. Two reviewers independently screened citations, extracted data, and assessed the risk of bias with the modified Newcastle-Ottawa Scale. We estimated pooled proportions and crude/adjusted odds ratio. RESULTS: We identified 95 eligible studies including 95,854 US-based survey respondents. A few studies (6.3%) focused on persons who inject drugs. In 2015-2017, men who have sex with men (MSM) had highest proportion of individuals who used PrEP over their lifetime [13.9% (95% confidence interval: 8.8 to 21.1), k (number of surveys) = 49] followed by Hispanic/Latinos [11.5 (7.1 to 18.1), 12], transgender women [11.2 (5.8 to 20.6), 5], and blacks [9.9 (8.3 to 11.8), 18]. Odds of PrEP use increased by 34%/year [odds ratio = 1.34/year (95% confidence interval: 1.09 to 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 United States [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 United States and youth, and understudied in persons who inject drugs. Limitations include few studies in certain years, whereas strengths include a large number of respondents. Culturally tailored approaches targeting vulnerable populations are essential in increasing PrEP use to reduce disparities in HIV acquisition.

Social Support and Other Factors Associated with HIV Testing by Hispanic/Latino Gay, Bisexual, and Other Men Who Have Sex with Men in the U.S. South.

Cognitive-psychosocial and other factors may affect participation in HIV testing, particularly by Hispanic/Latino gay, bisexual, and other men who have sex with men (MSM) in the U.S. South, a region hard-hit by HIV. We used univariate and multivariable logistic regression analyses to examine the association between social support and other cognitive-psychosocial factors; sociodemographic characteristics; risk behaviors; and self-reported HIV testing in a sample of 304 Hispanic/Latino MSM in North Carolina. In the multivariable logistic regression analysis, general and HIV-related social support and HIV-related knowledge were associated with greater odds of testing; speaking only Spanish was associated with reduced odds of testing. Social support and aspects of social connectedness may constitute community-based resources for use in HIV prevention efforts with Hispanic/Latino MSM. However, harnessing these resources for HIV prevention will require a better understanding of how social support relationships and processes shape HIV risks and protective actions by these vulnerable MSM.

Estimating the Prevalence of HIV and Sexual Behaviors Among the US Transgender Population: A Systematic Review and Meta-Analysis, 2006-2017.

Background. Transgender women (transwomen) in the United States have been shown to have high HIV risk with Black and Hispanic transwomen being particularly vulnerable. Growing research on transgender men (transmen) also shows increased HIV risk and burden, although not as much is known for this transgender population.Objectives. This systematic review estimates the prevalence of self-reported and laboratory-confirmed HIV infection, reported sexual and injection behaviors, and contextual factors associated with HIV risk of transgender persons living in the United States.Search Methods. We searched the HIV Prevention Research Synthesis database and MEDLINE, EMBASE, PsycINFO, CINAHL, and Sociological Abstracts databases from January 2006 to March 2017 and January 2006 to May 2017, respectively. Additional hand searches were conducted in December 2017 to obtain studies not found in the literature searches.Selection Criteria. Eligible reports were published US-based studies that included transgender persons and reported HIV status.Data collection and analysis. Data were double-coded and quality assessed. We used random-effects models employing the DerSimonian-Laird method to calculate overall prevalence of HIV infection, risk behaviors, and contextual factors for transwomen, transmen, and race/ethnicity subgroups.Main Results. We reviewed 88 studies, the majority of which were cross-sectional surveys. Overall laboratory-confirmed estimated prevalence of HIV infection was 9.2% (95% confidence interval [CI] = 6.0%, 13.7%; κ = 24). Among transwomen and transmen, HIV infection prevalence estimates were 14.1% (95% CI = 8.7%, 22.2%; κ = 13) and 3.2% (95% CI = 1.4%, 7.1%; κ = 8), respectively. Self-reported HIV infection was 16.1% (95% CI = 12.0%, 21.2%; κ = 44), 21.0% (95% CI = 15.9%, 27.2%; κ = 30), and 1.2% (95% CI = 0.4%, 3.1%; κ = 7) for overall, transwomen, and transmen, respectively. HIV infection estimates were highest among Blacks (44.2%; 95% CI = 23.2%, 67.5%; κ = 4). Overall, participation in sex work was 31.0% (95% CI = 23.9%, 39.0%; κ = 39). Transwomen (37.9%; 95% CI = 29.0%, 47.7%; κ = 29) reported higher participation in sex work than transmen (13.1%; 95% CI = 6.6%, 24.3%; κ = 10; P = .001). Most outcomes indicated high heterogeneity in the overall and subgroup analyses.Conclusions. The availability of more data allowed us to calculate estimates separately for transwomen and transmen. HIV prevalence estimates for US transwomen were lower than previous estimates, but estimates for HIV prevalence and participation in sex work were higher when compared with transmen. Evidence gaps remain for transmen and the syndemic relationship of HIV, risky behaviors, and contextual factors specific to the transgender experience.Public Health Implications. This study highlights gender disparities for HIV and risky sexual behavior, as well as evidence gaps that exist for transmen. Tailored programs and services for the transgender population need to be developed to encourage use of and access to HIV prevention services.

Increasing prevalence of self-reported HIV preexposure prophylaxis use in published surveys: a systematic review and meta-analysis.

: When combining results from all published surveys, about one in nine global study participants (10.7%) reported ever using preexposure prophylaxis (PrEP) by 2017, a significant increase since US FDA approval in 2012 [odds ratio (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 Centers for Disease Control and Prevention'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.

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 (ß = 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.

Evaluating the Evidence for More Frequent Than Annual HIV Screening of Gay, Bisexual, and Other Men Who Have Sex With Men in the United States: Results From a Systematic Review and CDC Expert Consultation.

The Centers for Disease Control and Prevention (CDC) recommended in 2006 that sexually active gay, bisexual, and other men who have sex with men (MSM) be screened for human immunodeficiency virus (HIV) at least annually. A workgroup comprising CDC and external experts conducted a systematic review of the literature, including benefits, harms, acceptability, and feasibility of annual versus more frequent screening among MSM, to determine whether evidence was sufficient to change the current recommendation. Four consultations with managers of public and nonprofit HIV testing programs, clinics, and mathematical modeling experts were conducted to provide input on the programmatic and scientific evidence. Mathematical models predicted that more frequent than annual screening of MSM could prevent some new HIV infections and would be more cost-effective than annual screening, but this evidence was considered insufficient due to study design. Evidence supports CDC's current recommendation that sexually active MSM be screened at least annually. However, some MSM might benefit from more frequent screening. Future research should evaluate which MSM subpopulations would benefit most from more frequent HIV screening.

Recommendations for HIV Screening of Gay, Bisexual, and Other Men Who Have Sex with Men - United States, 2017.

CDC's 2006 recommendations for human immunodeficiency virus (HIV) testing state that all persons aged 13-64 years should be screened for HIV at least once, and that persons at higher risk for HIV infection, including sexually active gay, bisexual, and other men who have sex with men (MSM), should be rescreened at least annually (1). Authors of reports published since 2006, including CDC (2), suggested that MSM, a group that is at highest risk for HIV infection, might benefit from being screened more frequently than once each year. In 2013, the U.S. Preventive Services Task Force (USPSTF) found insufficient evidence to specify an HIV rescreening interval but recommended annual screening for MSM as a reasonable approach (3). However, some HIV providers have begun to offer more frequent screening, such as once every 3 or 6 months, to some MSM. A CDC work group conducted a systematic literature review and held four expert consultations to review programmatic experience to determine whether there was sufficient evidence to change the 2006 CDC recommendation (i.e., at least annual HIV screening of MSM in clinical settings). The CDC work group concluded that the evidence remains insufficient to recommend screening more frequently than at least once each year. CDC continues to recommend that clinicians screen asymptomatic sexually active MSM at least annually. Each clinician can consider the benefits of offering more frequent screening (e.g., once every 3 or 6 months) to individual MSM at increased risk for acquiring HIV infection, weighing their patients' individual risk factors, local HIV epidemiology, and local testing policies.

Evaluating the Effectiveness of Physical Exercise Interventions in Persons Living With HIV: Overview of Systematic Reviews.

Physical exercise (PE) has not been well studied in persons living with HIV (PLHIV). We conducted an overview of systematic reviews to assess the effectiveness of PE and to determine the most appropriate PE regimen for PLHIV. We used the CDC's Prevention Research Synthesis Project's database and manual searches to identify systematic reviews published between 1996 and 2013. We qualitatively synthesized the findings from five reviews to assess the effectiveness of PE and conducted meta-analyses on CD4 counts to identify the best PE regimen. PE is associated with reduced adiposity and depression, but was not associated with a decrease in HIV viral load. CD4 counts were improved by interventions with interval aerobic or 41-50 minutes of exercise three times per week compared with other modes and duration of exercise. PE appears to benefit PLHIV, but more research is needed to help develop appropriate PE strategies specifically for PLHIV.

Identifying Best Practices for Increasing Linkage to, Retention, and Re-engagement in HIV Medical Care: Findings from a Systematic Review, 1996-2014.

A systematic review was conducted to identify best practices for increasing linkage, retention and re-engagement in HIV care (LRC) for persons living with HIV (PLWH). Our search strategy consisted of automated searches of electronic databases and hand searches of journals, reference lists and listservs. We developed two sets of criteria: evidence-based to identify evidence-based interventions (EBIs) tested with a comparison group and evidence-informed to identify evidence-informed interventions (EIs) tested with a one-group design. Eligible interventions included being published between 1996 and 2014, U.S.-based studies with a comparison or one-group designs with pre-post data, international randomized controlled trials, and having objective measures of LRC-relevant outcomes. We identified 10 best practices: 5 EBIs and 5 EIs. None focused on re-engagement. Providers and prevention planners can use the review findings to identify best practices suitable for their clinics, agencies, or communities to increase engagement in care for PLWH, ultimately leading to viral suppression.

Are couple-based interventions more effective than interventions delivered to individuals in promoting HIV protective behaviors? A meta-analysis.

Despite several advantages to bringing couples together to learn how to protect themselves and new-born children from the risk of HIV infection, most interventions are designed for individuals or groups, not for dyads. This meta-analysis provides a direct test of whether couple-based interventions are more effective in promoting HIV protective behaviors than interventions delivered to individuals. We conducted systematic searches of five electronic databases and 60 journals. Eligible studies were controlled trials or prospective cohort designs; evaluated a couple-based intervention compared to an individual-level intervention; assessed at least one HIV prevention outcome (e.g., protective sex, drug use, HIV testing, medication adherence, and sexually transmitted infections [STI]); and were published between 1988 and 2014. Fifteen interventions, including 21,882 participants from China, Kenya, Rwanda, Tanzania, Trinidad, Zambia, and the USA, were evaluated. The results of random-effects models showed statistically significant intervention effects for protective sex (OR = 1.60, 95% CI = 1.21, 2.11), HIV testing (OR = 1.79, 95% CI = 1.31, 2.45), and Nevirapine uptake (OR = 1.51, 95% CI = 1.02, 2.24). The evidence demonstrates the usefulness of couple-based interventions in protecting individuals, partners, and new-born children from the risk of HIV transmission and infection.

Effects of integrated interventions on transmission risk and care continuum outcomes in persons living with HIV: meta-analysis, 1996-2014.

BACKGROUND: Reducing HIV infection and improving outcomes along the continuum of HIV care are high priorities of the US National HIV/AIDS strategy. Interventions that target multiple problem behaviors simultaneously in an integrated approach (referred to as integrated interventions) may improve prevention and care outcomes of persons living with HIV (PLWH). This systematic review and meta-analysis examines the effects of integrated interventions. METHODS: A systematic review, including both electronic and hand searches, was conducted to identify randomized controlled trials (RCTs) published between 1996 and 2014 that were designed to target at least two of the following behaviors among PLWH: HIV transmission risk behaviors, HIV care engagement, and medication adherence. Effect sizes were meta-analyzed using random-effects models. RESULTS: Fifteen RCTs met the inclusion criteria. Integrated interventions significantly reduced sex without condoms [odds ratio (OR) = 0.74, 95% confidence interval (CI) = 0.59, 0.94, P = 0.013, 13 effect sizes] and had marginally significant effects on improving medication adherence behaviors (OR = 1.35, 95% CI = 0.98, 1.85, P = 0.063, 12 effect sizes) and undetectable viral load (OR = 1.46, 95% CI = 0.93, 2.27, P = 0.098, seven effect sizes). Significant intervention effects on at least two outcomes were seen in RCTs tailored to individual needs, delivered one on one, or in settings wherein PLWH received services or care. CONCLUSION: Integrated interventions produced some favorable prevention and care continuum outcomes in PLWH. How to incorporate integrated interventions with other combination HIV prevention strategies to reach the optimal impact requires further research.

A systematic review of interventions for reducing HIV risk behaviors among people living with HIV in the United States, 1988-2012.

OBJECTIVE: To conduct a systematic review to examine interventions for reducing HIV risk behaviors among people living with HIV (PLWH) in the United States. METHODS: Systematic searches included electronic databases from 1988 to 2012, hand searches of journals, reference lists of articles, and HIV/AIDS Internet listservs. Each eligible study was evaluated against the established criteria on study design, implementation, analysis, and strength of findings to assess the risk of bias and intervention effects. RESULTS: Forty-eight studies were evaluated. Fourteen studies (29%) with both low risk of bias and significant positive intervention effects in reducing HIV transmission risk behaviors were classified as evidence-based interventions (EBIs). Thirty-four studies were classified as non-EBIs due to high risk of bias or nonsignificant positive intervention effects. EBIs varied in delivery from brief prevention messages to intensive multisession interventions. The key components of EBIs included addressing HIV risk reduction behaviors, motivation for behavioral change, misconception about HIV, and issues related to mental health, medication adherence, and HIV transmission risk behavior. CONCLUSION: Moving evidence-based prevention for PLWH into practice is an important step in making a greater impact on the HIV epidemic. Efficacious EBIs can serve as model programs for providers in healthcare and nonhealthcare settings looking to implement evidence-based HIV prevention. Clinics and public health agencies at the state, local, and federal levels can use the results of this review as a resource when making decisions that meet the needs of PLWH to achieve the greatest impact on the HIV epidemic.
