Despite its benefit for treating active tuberculosis, directly observed therapy (DOT) for latent tuberculosis infection (LTBI) has been largely understudied among challenging inner city populations. Utilizing questionnaire data from a comprehensive mobile healthcare clinic in New Haven, CT from 2003 to July 2011, a total of 2,523 completed tuberculin skin(More)
Retention in care is key to effective HIV treatment, but half of PLWHA in the US are continuously engaged in care. Incarcerated individuals are an especially challenging population to retain, and empiric data specific to jail detainees is lacking. We prospectively evaluated correlates of retention in care for 867 HIV-infected jail detainees enrolled in a(More)
Despite new Hepatitis C virus (HCV) therapeutic advances, challenges remain for HCV testing and linking patients to care. A point-of-care (POC) HCV antibody testing strategy was compared to traditional serological testing to determine patient preferences for type of testing and linkage to treatment in an innovative mobile medical clinic (MMC). From 2012 to(More)
Drug users are marginalized from typical primary care, often resulting in emergency department (ED) usage and hospitalization due to late-stage disease. Though data suggest methadone decreases such fragmented healthcare utilization (HCU), the impact of buprenorphine maintenance treatment (BMT) on HCU is unknown. Chart review was conducted on opioid(More)
BACKGROUND Overdose is the leading cause of death among opioid users, but no data are available on overdose among people who inject drugs in Malaysia. We present the first estimates of the prevalence and correlates of recent non-fatal overdose among people who inject drugs in Malaysia. METHODS In 2010, 460 people who inject drugs were recruited using(More)
BACKGROUND HCV prevalence estimates among people who inject drugs (PWID) in Ukraine is high (60-90%), yet barriers to HCV treatment and care remain substantial including limited access to direct acting antiviral (DAA) medications. A feasibility scale-up project implemented HCV treatment in community-based settings to improve access to DAA treatment for key(More)
OBJECTIVES We assessed gender differences in longitudinal HIV treatment outcomes among HIV-infected jail detainees transitioning to the community. METHODS Data were from the largest multisite prospective cohort study of HIV-infected released jail detainees (n = 1270)-the Enhancing Linkages to HIV Primary Care and Services in Jail Setting Initiative,(More)
This empirical study examines the association between substance abuse, mental illness, health behaviors and different patterns of homelessness among recently released, HIV-infected jail detainees. Using longitudinal data from a 10-site study, we examine correlates of homelessness, transitions to and from stable housing and the effect of housing on HIV(More)
Incarceration, particularly when recurrent, can significantly compromise the health of individuals living with HIV. Despite this, the occurrence of recidivism among individuals with HIV has been little examined, particularly among those leaving jail, who may be at especially high risk for return to the criminal justice system. We evaluated individual- and(More)
OBJECTIVES We evaluated the efficacy of a mobile medical clinic (MMC) screening program for detecting latent tuberculosis infection (LTBI) and active tuberculosis. METHODS A LTBI screening program in a MMC in New Haven, Connecticut, used medical surveys to examine risk factors and tuberculin skin test (TST) screening eligibility. We assessed clinically(More)
