Housing Instability Associated with Return to Stimulant Use among Previously Abstaining Women
Stimulant use among unstably housed individuals is associated with increased risks of psychiatric co-morbidity, violence, HIV transmission, and overdose. Due to a lack of highly effective treatments, evidence-based policies targeting the prevention of stimulant use disorder are of critical importance. However, little empirical evidence exists on risks associated with initiating or returning to stimulant use among at-risk populations. In a longitu…
Randomized Controlled Trial of Automated Directly Observed Therapy for Measurement and Support of PrEP Adherence Among Young Men Who have Sex with Men
Measurement of adherence to oral pre-exposure prophylaxis (PrEP) in real-time has been challenging. We developed DOT Diary, a smartphone application that combines automated directly observed therapy with a PrEP adherence visualization toolkit, and tested its ability to measure PrEP adherence and to increase adherence among a diverse cohort of young men who have sex with men (MSM). We enrolled 100 MSM in San Francisco and Atlanta and randomly assi…

Preexposure Prophylaxis for HIV Infection Integrated With Municipal- and Community-Based Sexual Health Services
IMPORTANCE: Several randomized clinical trials have demonstrated the efficacy of preexposure prophylaxis (PrEP) in preventing human immunodeficiency virus (HIV) acquisition. Little is known about adherence to the regimen, sexual practices, and overall effectiveness when PrEP is implemented in clinics that treat sexually transmitted infections (STIs) and community-based clinics serving men who have sex with men (MSM). OBJECTIVE: To assess PrEP adh…
Binge drinking concurrent with anal intercourse and condom use among men who have sex with men
Men who have sex with men (MSM) are the demographic group most severely affected by HIV in the USA. Global association studies have shown that MSM who binge drink are more likely to engage in risky sexual behaviors and day- and event-level analyses have linked binge drinking to sexual risk behavior on specific days and during specific sexual encounters. Despite this strong foundation of research, no studies have examined the association between t…

Hepatitis C Screening Rate Among Underserved Adults With Serious Mental Illness Receiving Care in California Community Mental Health Centers
Although HCV is more prevalent among people with severe mental illness (SMI; e.g., schizophrenia, bipolar disorder) than in the general population (17% vs 1%), no large previous studies have examined HCV screening in this population. In this cross-sectional study, we examined administrative data for 57 170 California Medicaid enrollees with SMI to identify prevalence and predictors of HCV screening from October 2010 through September 2011. Only 4…

A randomized control trial of personalized cognitive counseling to reduce sexual risk among HIV-infected men who have sex with men
The increased life expectancy and well-being of HIV-infected persons presents the need for effective prevention methods in this population. Personalized cognitive counseling (PCC) has been shown to reduce unprotected anal intercourse (UAI) with a partner of unknown or different serostatus among HIV-uninfected men who have sex with men (MSM). We adapted PCC for use among HIV-infected MSM and tested its efficacy against standard risk-reduction coun…

Drug Use and Sexual Risk Behavior Among Gay and Bisexual Men Who Attend Circuit Parties
CONTEXT: HIV risk behavior among urban gay/bisexual men has recently increased. High-risk sexual activity and drug use may be particularly high during circuit party (CP) weekends, during which gay/bisexual men congregate for social activities and dancing. OBJECTIVES: To compare prevalence of risk behaviors during CP weekends with those during non-CP weekends. DESIGN: Cross-sectional study. PARTICIPANTS: 295 gay/bisexual men from the San Francisco…
What happened to home HIV test collection kits? Intent to use kits, actual use, and barriers to use among persons at risk for HIV infection
Through sequential cross-sectional surveys, we examined intent to use home HIV test collection kits, actual use and barriers to use among persons at high risk for HIV infection. Interest in kits was assessed in the 1995-96 HIV Testing Survey (HITS, n=1683). Kit use, knowledge of kits and barriers to use were assessed in the 1998-99 HITS (n=1788), after kits had become widely available. When asked to choose among future testing options, 19% of 199…
Reduced Risk of Inadequate Prenatal Care in the Era After Medicaid Expansions in California
BACKGROUND: To improve perinatal outcomes in the United States, access to prenatal care was expanded through Medicaid and women were encouraged to enter prenatal care early. OBJECTIVE: The objective of this study was to determine if expanded eligibility for Medicaid increased use of prenatal care and reduced ethnic differences in use of prenatal care. RESEARCH DESIGN: We conducted secondary analysis of California birth certificate data for 1990, …
Communication of HIV viral load to guide sexual risk decisions with serodiscordant partners among San Francisco men who have sex with men
The objective of this study was to estimate frequency and correlates of discussing HIV viral load (VL) with serodiscordant sex partners to guide decisions about sexual activities among men who have sex with men (MSM). We conducted a cross-sectional survey of 573 San Francisco MSM. Among 507 who knew their HIV status, 397 (78%) were familiar with the term 'viral load', and half (n=199) had a serodiscordant partner in the prior year. These 199 resp…
Relaxing the Rule of Ten Events per Variable in Logistic and Cox Regression
The rule of thumb that logistic and Cox models should be used with a minimum of 10 outcome events per predictor variable (EPV), based on two simulation studies, may be too conservative. The authors conducted a large simulation study of other influences on confidence interval coverage, type I error, relative bias, and other model performance measures. They found a range of circumstances in which coverage and bias were within acceptable levels desp…

Quality of Care in Hospitals with a High Percent of Medicaid Patients
BACKGROUND: Certain hospitals play a central role in ensuring Medicaid-insured patients' access to care. Their quality of care is critical to evaluate. OBJECTIVE: To determine whether hospitals for which Medicaid patients represent a high percentage of total discharges provide a different quality of care than other hospitals. RESEARCH DESIGN: Cross-sectional analysis. SUBJECTS: Acute care hospitals participating in the first Hospital Compare publ…
Association between the Level of Housing Instability, Economic Standing and Health Care Access
Introduction . To determine the relationship between housing instability, economic standing, and access to health care and use of acute care services. Methods . We performed a meta-regression using four nationally representative surveys. The independent variable was an ordered measure of economic and housing instability: 1) the general population, 2) low-income population, 3) never homeless users-of-subsistence-services, 4) unstably housed, 5) fo…
The Influence of Depressive Symptoms on Clinician–Patient Communication Among Patients With Type 2 Diabetes
BACKGROUND: Depression is associated with poor chronic illness outcomes, but it is unknown whether depression influences the quality of communication during the clinical encounter. We investigated whether diabetes patients with depressive symptoms, compared with those without depressive symptoms, report worse clinician-patient communication, and which domains of communication are most affected. METHODS: We surveyed 231 ethnically diverse, English…

Relationship Between Discharge Practices and Intensive Care Unit In-Hospital Mortality Performance
CONTEXT: Current intensive care unit performance measures include in-hospital mortality after intensive care unit admission. This measure does not account for deaths occurring after transfer to another hospital or soon after discharge and therefore, may be biased. OBJECTIVE: Determine how transfer rates to other acute care hospitals and early post-discharge mortality rates impact hospital performance assessments using an in-hospital mortality mod…

Decreases in Community Viral Load Are Accompanied by Reductions in New HIV Infections in San Francisco
BACKGROUND: At the individual level, higher HIV viral load predicts sexual transmission risk. We evaluated San Francisco's community viral load (CVL) as a population level marker of HIV transmission risk. We hypothesized that the decrease in CVL in San Francisco from 2004-2008, corresponding with increased rates of HIV testing, antiretroviral therapy (ART) coverage and effectiveness, and population-level virologic suppression, would be associated…

Efficacy of Personalized Cognitive Counseling in Men of Color who Have Sex with Men
In a previous report, we demonstrated the efficacy of a cognitively based counseling intervention compared to standard counseling at reducing episodes of unprotected anal intercourse (UAI) among men who have sex with men (MSM) seeking HIV testing. Given the limited number of efficacious prevention interventions for MSM of color (MOC) available, we analyzed the data stratified into MOC and whites. The sample included 196 white MSM and 109 MOC (23 …
