Improved Gonorrhea and Chlamydia Testing Among Men Who Have Sex With Men Living With HIV Through Implementation of Self-Collected Tests.

ABSTRACT: We implemented self-collected gonorrhea/chlamydia testing in 17 medical centers in California serving men who have sex with men living with HIV. From 2012 to 2018, gonorrhea/chlamydia testing increased from 45.2% to 63.4%. Among those tested, rectal testing increased from 42.0% to 77.3%; pharyngeal testing increased from 31.0% to 79.9% (all, Ptrend < 0.0001).

Determination of optimized multidisciplinary care team for maximal antiretroviral therapy adherence.

OBJECTIVE: We seek to determine the optimized multidisciplinary care team (MDCT) composition for antiretroviral therapy (ART) adherence. METHODS: We analyzed all new regimen starts (n = 10,801; 7071 ART naive, 3730 ART experienced) among HIV-positive patients in Kaiser Permanente California from 1996 to 2006. We measured 12-month adherence to ART (pharmacy refill methodology) and medical center-specific patient exposure to HIV/infectious disease specialist (reference group), non-HIV primary care provider, clinical pharmacist, nurse case manager, non-nurse care coordinator, dietician, social worker/benefits coordinator, health educator, and mental health worker. We used recursive partitioning to ascertain potential MDCT compositions associated with maximal mean ART adherence. We then employed mixed linear regression with clustering by provider and medical center (adjusting for ART experience, age, gender, race/ethnicity, HIV risk, hepatitis C virus coinfection, ART regimen class, and calendar year) to test which potential MDCT combination identified had statistically significant association with ART adherence. RESULTS: We found maximal increase in adherence with pharmacist plus coordinator plus primary care provider combination (8.1% ART adherence difference compared with reference; 95% confidence interval: 2.7% to 13.5%). Other MDCT teams with significantly (P < 0.05) improved adherence compared with specialist only were nurse plus social worker with primary care provider (7.5%; 5.4% to 9.7%), specialist plus mental health worker (6.5%; 2.6% to 10.4%), pharmacist plus social worker plus primary care provider (5.7%; 4.1% to 7.4%), and pharmacist plus primary care provider (3.3%; 0.8% to 5.8%). Among these MDCTs, there were no significant differences in mean adherence, odds of maximal viral control, or CD4+ changes at 12 months (except pharmacist plus primary care provider). CONCLUSIONS: Various MDCTs were associated with improved adherence, including ones that did not include the HIV specialist but included primary care plus other health professionals. These findings have application to the HIV care team design.

Influence of provider experience on antiretroviral adherence and viral suppression.

BACKGROUND AND AIM: Early in the combination antiretroviral therapy (cART) era, provider experience (as measured by panel size) was associated with improved outcomes. We explored that association and other characteristics of provider experience. METHODS: We performed a retrospective cohort analysis in Kaiser Permanente California (an integrated health care system in the United States), examining all human immunodeficiency virus seropositive (HIV+) patients initiating a first cART regimen (antiretroviral therapy [ART]-naïve, N = 7071) or initiating a second or later cART regimen (ART-experienced, N = 3730) from 1996-2006. We measured ART adherence through 12 months (pharmacy fill and refill records) and determined HIV viral load levels below limits of quantification at 12 months. Provider experience, updated annually, was measured as (1) HIV panel size (0-10 patients as reference strata), (2) years treating HIV (less than 1 year as reference), and (3) specialty ( noninfectious disease specialty, non-HIV expert as reference). We assessed associations by utilizing mixed modeling analyses (clustered by provider and medical center), controlling for patient age, sex, race/ethnicity, HIV risk behavior, hepatitis C coinfection, ART regimen class, and calendar year. RESULTS: Among the ART-experienced, improved adherence was associated with greater years experience (mean increase 3.1% 2-5 years experience; 3.7% 5-10 years; 2.7% 11-20 years; P = 0.07, categorical). In adjusted analyses, viral suppression among ART-naïve was positively associated with panel size (odds ratio 26-50 patients: 1.31, P = 0.03, categorical), but negatively associated with years experience (18% less for greater than 100 patients; P = 0.003). No provider characteristic was significantly associated with improved adherence among ART-naïve or odds of maximal viral suppression among ART-experienced in adjusted analysis. CONCLUSIONS: Except for panel size and years experience among ART-naïve, provider characteristics did not significantly influence ART adherence or likelihood of viral suppression.
