HIV-positive Latino and African-American young men who have sex with men (YMSM) have low rates of engagement and retention in HIV care. An evaluation of a youth-focused case management intervention (YCM) designed to improve retention in HIV care is presented. HIV-positive Latino and African-American YMSM, ages 18-24, who were newly diagnosed with HIV or in intermittent HIV care, were enrolled into a psychosocial case management intervention administered by Bachelor-level peer case managers at two HIV clinics in Los Angeles County, California. Participants met weekly with a case manager for the first two months and monthly for the next 22 months. Retention in HIV primary care at three and six months of follow-up was evaluated as were factors associated with retention in care. From April 2006 to April 2009, 61 HIV-positive participants were enrolled into the intervention (54% African-American, 46% Latino; mean age 21 years). At the time of enrollment into the intervention, 78% of the YMSM had a critical or immediate need for stable housing, nutrition support, substance abuse treatment, or mental health services. Among intervention participants (n=61), 90% were retained in primary HIV care at three months and 70% at six months. Among those who had previously been in intermittent care (n=33), the proportion attending all HIV primary care visits in the previous six months increased from 7% to 73% following participation in the intervention (p<0.0001). Retention in HIV care at six months was associated with increased number of intervention visits (p=0.05), more hours in the intervention (p=0.02), and prescription of HAART. These data highlight the critical needs of HIV-positive African-American and Latino YMSM and demonstrate that a clinic-based YCM can be effective in stabilizing hard-to-reach clients and retaining them in consistent HIV care.
Homeless men who have sex with men (MSM) are a particularly vulnerable population with high rates of substance dependence, psychiatric disorders, and HIV prevalence. Most need strong incentives to engage with community-based prevention and treatment programs. Contingency Management (CM) was implemented in a community HIV prevention setting and targeted reduced substance use and increased health-promoting behaviors over a 24-week intervention period. Participants in the CM condition achieved greater reductions in stimulant and alcohol use (χ2 = 27.36, p<.01) and, in particular, methamphetamine use (χ2 = 21.78, p<.01), and greater increases in health-promoting behaviors (χ2 = 37.83, p<.01) during the intervention period than those in the control group. Reductions in substance use were maintained to 9- and 12-month follow-up evaluations. Findings indicate the utility of CM for this high-risk population and the feasibility of implementing the intervention in a community-based HIV prevention program.
There were significant increases in rectal chlamydia and syphilis diagnoses when comparing the periods directly before and after PrEP initiation. However, only 28% of individuals had an increase in STIs between periods. Although risk compensation appears to be present for a segment of PrEP users, the majority of individuals either maintain or decrease their sexual risk following PrEP initiation.
BACKGROUND TDF/FTC PrEP is effective against rectal HIV acquisition when taken as prescribed. Strategies that identify and intervene with those challenged by adherence to daily medication are needed. SETTING PATH-PrEP was an open-label single arm interventional cohort study conducted at 2 community-based clinical sites in Los Angeles, California. METHODS We enrolled self-identified MSM and TGW ≥18 years of age at elevated risk of HIV acquisition. Participants received a PEP or PrEP-based HIV prevention package for at least 48 weeks. Plasma TFV levels from each PrEP visit assessed as below the limit of quantiatation (<10 ng/mL) triggered increased adherence support. RESULTS 301 participants enrolled. Forty-eight-week retention in the PrEP cohort was 75.1%. Biomarker evidence of PrEP adherence consistent with ≥4 doses per week at weeks 4, 12, 24, 36, and 48 were found in 83.1%, 83.4%, 75.7%, 71.6%, and 65.5% of participants; younger and African-American participants were less likely to have protective drug levels. Most of those with suboptimal adherence had adherence improvement after brief intervention. One seroconversion occurred in a participant who discontinued PrEP. Nearly half (46.4%) of participants were diagnosed with at least one incident STI during 48 weeks of study follow-up. CONCLUSIONS AND RELEVANCE PrEP was acceptable and well tolerated in a diverse population of MSM in Los Angeles. A brief intervention triggered from biomarkers of poor adherence was associated with improved adherence. Drug level monitoring has the potential to allow targeting of additional adherence support to those struggling with daily tablet adherence.
The Navigation Program is a health department-community agency collaboration to reengage lost HIV clinic patients in Los Angeles County using best practices from disease investigator services locator activities and the Antiretroviral Treatment Access Study (ARTAS), a CDC-recommended intervention. Clinic databases were reviewed to identify HIV patients who: (1) had no HIV care visits in 6-12 months and last viral load was greater than 200 copies per milliliter; (2) had no HIV care visits in >12 months; (3) were newly diagnosed and never in care; or (4) were recently released from jail/prison/other institution with no regular HIV medical provider. Patients were contacted by trained Navigators using locator information from clinic medical records, HIV/sexually transmitted disease surveillance, and people-finder databases and offered enrollment in a modified ARTAS intervention. Among the 1139 lost clinic patients identified, 36% were in care elsewhere, 29% could not be located, 8% returned to the clinic independently, 4% declined enrollment, and 7% (n = 78) were located and enrolled in the intervention. Participants received an average of 4.5 Navigator sessions over 11.6 hours. Among reengaged patients, 68% linked within 3 months, 85% linked within 6 months, and 94% linked within 12 months, and 82% of linked patients were retained in care 12 months after study enrollment. The percentage of linked patients virally suppressed was compared at time of linkage by the Navigators (52%) with a second viral load measure after linkage to care (63%) (χ(2) = 11.8; P = 0.01). The combined disease investigator services/ARTAS model of reengagement was effective for locating and reengaging lost HIV clinic patients. Access to HIV surveillance data is critical for the efficient identification of persons truly in need of reengagement.
