Facilitators and Barriers to Expedited Partner Therapy: Results from a Survey of Family Physicians
Background
Expedited partner therapy (EPT) can prevent transmission of sexually transmitted infections (STIs) and reinfection of the index patient. We surveyed family physicians (FPs) in British Columbia to understand their perceptions of barriers and facilitators to EPT use and explored how perceptions varied by demographic and practice characteristics. Methods
Survey participants were recruited through the Divisions of Family Practice, which include greater than 90% of FPs in British Columbia. Common barriers and facilitators for EPT were identified using descriptive statistics. The association between each EPT barrier and facilitator and demographic and practice characteristics were tested using χ2 test. Results
One hundred eighty-one FPs started the survey, of which 146 (80.7%) answered 10 questions or more and were analyzed. Overall, inaccurate information about sex partners (88 [60.3%] of 146) and medicolegal concerns (87 [59.6%] of 146) were the most common barriers reported. Family physicians in nonurban settings were more likely to identify insufficient time as a barrier compared with FPs in urban settings (P \u3c 0.01). The most common facilitators were having a health care professional for follow-up after prescribing EPT (110 [75.3%] of 146), improved remuneration (93 [63.7%] of 146), clear clinical guidelines around EPT (87/146, 59.6%), and having a legal framework (92 [63.0%] of 146). Family physicians practicing for less than 9 years (the median) were more likely to identify the latter as facilitating EPT compared with FPs practicing for 9 years or longer (P \u3c 0.05). Conclusions
Ensuring patients have access to a health care professional for follow-up, improved remuneration, and development of clinical guidelines and a legal framework can support the implementation of EPT. Tools catered to different practice types and contexts may help increase EPT use

Effect of opioid-substitution therapy and mental health counseling on HIV risk among hepatitis C-infected individuals
Understanding differences in HIV incidence among people living with hepatitis C virus (HCV) can help inform strategies to prevent HIV infection. We estimated the time to HIV diagnosis among HCV-positive individuals and evaluated factors that could affect HIV-infection risk in this population.
The British Columbia Hepatitis Testers Cohort includes all BC residents (~1.5 million: about a third of all residents) tested for HCV and HIV from 1990 to 2013 and is linked to administrative health care and mortality data. All HCV-positive and HIV-negative individuals were followed to measure time to HIV acquisition (positive test) and identify factors associated with HIV acquisition. Adjusted HRs (aHRs) were estimated using Cox proportional-hazard regression.
Of 36,077 HCV-positive individuals, 2,169 (6%) acquired HIV over 266,883 years of follow-up (overall incidence of 8.1 per 1,000 person years). Overall median (IQR) time to HIV infection was 3.87 (6.06) years. In Cox regression, injection-drug use (aHR 1.47, 95% CI 1.33-1.63), HBV infection (aHR 1.34, 95% CI 1.16-1.55), and being a man who has sex with men (aHR 2.78, 95% CI 2.14-3.61) were associated with higher risk of HIV infection. Opioid-substitution therapy (OST) (aHR 0.59, 95% CI 0.52-0.67) and mental health counseling (aHR 0.48, 95% CI 0.43-0.53) were associated with lower risk of HIV infection.
Injection-drug use, HBV coinfection, and being a man who has sex with men were associated with increased HIV risk and engagement in OST and mental health counseling were associated with reduced HIV risk among HCV-positive individuals. Improving access to OST and mental health services could prevent transmission of HIV and other blood-borne infections, especially in settings where access is limited
A syndemic approach to assess the effect of substance use and social disparities on the evolution of HIV/HCV infections in British Columbia.
Co-occurrence of social conditions and infections may affect HIV/HCV disease risk and progression. We examined the changes in relationship of these social conditions and infections on HIV and hepatitis C virus (HCV) infections over time in British Columbia during 1990-2013.The BC Hepatitis Testers Cohort (BC-HTC) includes ~1.5 million individuals tested for HIV or HCV, or reported as a case of HCV, HIV, HBV, or tuberculosis linked to administrative healthcare databases. We classified HCV and HIV infection status into five combinations: HIV-/HCV-, HIV+monoinfected, HIV-/HCV+seroconverters, HIV-/HCV+prevalent, and HIV+/HCV+.Of 1.37 million eligible individuals, 4.1% were HIV-/HCV+prevalent, 0.5% HIV+monoinfected, 0.3% HIV+/HCV+ co-infected and 0.5% HIV-/HCV+seroconverters. Overall, HIV+monoinfected individuals lived in urban areas (92%), had low injection drug use (IDU) (4%), problematic alcohol use (4%) and were materially more privileged than other groups. HIV+/HCV+ co-infected and HIV-/HCV+seroconverters were materially most deprived (37%, 32%), had higher IDU (28%, 49%), problematic alcohol use (14%, 17%) and major mental illnesses (12%, 21%). IDU, opioid substitution therapy, and material deprivation increased in HIV-/HCV+seroconverters over time. In multivariable multinomial regression models, over time, the odds of IDU declined among HIV-/HCV+prevalent and HIV+monoinfected individuals but not in HIV-/HCV+seroconverters. Declines in odds of problematic alcohol use were observed in HIV-/HCV+seroconverters and coinfected individuals over time.These results highlight need for designing prevention, care and support services for HIV and HCV infected populations based on the evolving syndemics of infections and social conditions which vary across groups
