Partner notification by family physicians for sexually transmitted infections: Facilitators and barriers.

OBJECTIVE: To explore Canadian FPs' experiences with, perceived barriers to, and perceived facilitators of FP-initiated partner notification (PN) for HIV and other sexually transmitted infections (STIs), as well as to inform the development of tools that might enhance this work. DESIGN: Online survey. SETTING: British Columbia. PARTICIPANTS: A total of 146 FPs recruited through the Divisions of Family Practice community-based networks of FPs throughout the province. MAIN OUTCOME MEASURES: Family physicians' current STI and PN practices, opinions regarding FP-initiated PN, perceived barriers to and facilitators of FP-initiated PN, and preferred PN resources. RESULTS: More than 90% of FPs had diagnosed an STI within the past year, and most (60.3% to 96.6%, depending on the STI) told patients to inform their partners. Two-thirds (66.4%) felt that PN should not be done by FPs, and fewer than 10% reported contacting partners. Reported barriers included inaccurate or incomplete lists of partners (67.1%), poor compensation (54.1%), and insufficient time (54.1%). Facilitators chosen by respondents included another health professional assigned to follow up with PN (77.4%) and improved remuneration (74.7%). Electronic PN tools directed at patients (eg, PN slips) were favoured over resources directed at providers. CONCLUSION: Family physicians regularly manage STIs and currently take part in PN primarily through educating index cases. However, most do not feel that PN should be conducted by FPs, and most believe that FP-initiated PN would require additional personnel, remuneration, and legal guidance.

Population-Level Outcomes of Partner Notification Among Gay, Bisexual, and Other Men Who Report Sex With Men Diagnosed With Infectious Syphilis in British Columbia, Canada.

BACKGROUND: Syphilis testing, treatment, and partner notification (PN) are centrally coordinated in British Columbia (BC), Canada. Public health (PH) nurses (PHNs) contact almost all syphilis patients and either notify partners of syphilis exposure (PH-initiated PN) or support patients to notify their own partners (patient-initiated PN). In the context of an ongoing syphilis epidemic among gay, bisexual, and other men who report sex with men (gbMSM), we measured population-level yields and compared PN approaches to inform prevention and control efforts. METHODS: All gbMSM diagnosed with infectious syphilis in 2016 in BC were included. We calculated indicators of engagement with PN among patients and PN outcomes among notifiable partners using a cascade-of-care framework. χ2 Tests compared indicators between PN approaches. RESULTS: Of the 759 syphilis diagnoses, 85.4% (648/759) were among gbMSM and 94.7% (614/648) were treated within 30 days of testing (mean [SD], 5.5 [5.2] days). Among patients, 87.7% (568/648) discussed PN with PHNs and 49.5% (281/568) named at least 1 notifiable partner, for a total of 1094 partners (mean [SD], 3.9 [5.5] partners/patient). Compared with PH-initiated PN, patient-initiated PN resulted in a greater proportion of partners notified (70.1% [573/817] vs. 89.8% [211/235]; P = 1.88 × 10-9), but there was no difference in the proportion of partners tested and/or treated (90.2% [517/573] vs. 86.7% [183/211]; P = 0.203), and diagnosed (12.8% [66/517] vs. 16.4% [30/183]; P > 0.271). CONCLUSIONS: Public health- and patient-initiated PN had similarly high yields of partners tested and/or treated, and diagnosed, demonstrating that gbMSM can contribute to syphilis PN when supported by resource-equipped PHNs.

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 χ 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 < 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 < 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.

The Need and Desire for Mental Health and Substance Use-Related Services Among Clients of Publicly Funded Sexually Transmitted Infection Clinics in Vancouver, Canada.

CONTEXT: Sexually transmitted infections (STI) and mental health and substance use (MHSU) disorders all occur at elevated rates in sexual and gender minorities. These overlapping epidemics, or syndemics, are exacerbated by challenges these same populations face in accessing sexual/gender minority-affirming services. Many publicly funded STI clinics are a low barrier and provide sexual minority-competent care. These sites therefore may be uniquely situated to address clients' MHSU-related needs. OBJECTIVE: We characterize the need and desire for MHSU services among STI clinic clients. DESIGN, SETTING, PARTICIPANTS: We conducted a waiting room survey at 6 STI clinics in Metro Vancouver, Canada. MAIN OUTCOME MEASURES: We calculated the proportion of clients with self-reported unmet MHSU needs in the previous 12 months and, among these clients, barriers to accessing MHSU services and desire for MHSU services within the STI clinic. We also examined social disparities in barriers to accessing MHSU services. RESULTS: Among 1115 respondents-65% of whom were sexual minorities-39% reported a recent need for MHSU-related care, most frequently in relation to anxiety (29%), depression (26%), substance use (10%), or suicide ideation (7%). Seventy-two percent of this group had not yet talked to a provider about their concern. Common barriers included shame (26%) and inability to afford the service (24%). Eighty-three percent of clients with unmet MHSU needs indicated that they were comfortable discussing MHSU concerns with an STI clinic provider, and 94% expressed desire to receive MHSU assessments, referrals, or counseling in the STI clinic. Sexual and gender minorities and those attending a suburban clinic were more likely to report barriers to accessing MHSU services. CONCLUSIONS: More than a quarter of STI clinic clients report unmet MHSU health care needs; moreover, these clients report high levels of comfort with and desire to discuss MHSU concerns with STI clinic providers. Sexually transmitted infections clinics are thus opportune sites for syndemic service integration.

Identification of people with low prevalence diseases in administrative healthcare records: A case study of HIV in British Columbia, Canada.

INTRODUCTION: Case-finding algorithms can be applied to administrative healthcare records to identify people with diseases, including people with HIV (PWH). When supplementing an existing registry of a low prevalence disease, near-perfect specificity helps minimize impacts of adding in algorithm-identified false positive cases. We evaluated the performance of algorithms applied to healthcare records to supplement an HIV registry in British Columbia (BC), Canada. METHODS: We applied algorithms based on HIV-related diagnostic codes to healthcare practitioner and hospitalization records. We evaluated 28 algorithms in a validation sub-sample of 7,124 persons with positive HIV tests (2,817 with a prior negative test) from the STOP HIV/AIDS data linkage-a linkage of healthcare, clinical, and HIV test records for PWH in BC, resembling a disease registry (1996-2020). Algorithms were primarily assessed based on their specificity-derived from this validation sub-sample-and their impact on the estimate of the total number of PWH in BC as of 2020. RESULTS: In the validation sub-sample, median age at positive HIV test was 37 years (Q1: 30, Q3: 46), 80.1% were men, and 48.9% resided in the Vancouver Coastal Health Authority. For all algorithms, specificity exceeded 97% and sensitivity ranged from 81% to 95%. To supplement the HIV registry, we selected an algorithm with 99.89% (95% CI: 99.76% - 100.00%) specificity and 82.21% (95% CI: 81.26% - 83.16%) sensitivity, requiring five HIV-related healthcare practitioner encounters or two HIV-related hospitalizations within a 12-month window, or one hospitalization with HIV as the most responsible diagnosis. Upon adding PWH identified by this highly-specific algorithm to the registry, 8,774 PWH were present in BC as of March 2020, of whom 333 (3.8%) were algorithm-identified. DISCUSSION: In the context of an existing low prevalence disease registry, the results of our validation study demonstrate the value of highly-specific case-finding algorithms applied to administrative healthcare records to enhance our ability to estimate the number of PWH living in BC.

Cost-effective smoke-free multiunit housing media campaigns: connecting with local communities.

Presented are cost-effective paid media strategies to educate Californians to advocate for stronger smoke-free multiunit housing (SF-MUH) policies between 2006 and 2008. Included is a summary of general market and specific ethnic market costs that correspond to SF-MUH attitudes and home smoking bans. Statewide questionnaires indicated that half of the intended general market saw an antitobacco TV ad and half of the intended ethnic markets heard radio ads. Analyses indicated that it cost $0.67 and $0.78 per person to see Caution Tape and Apartment TV ads, respectively. Slightly higher per capita costs corresponded with positive attitudes toward SF-MUH: $0.87 for Caution Tape and $1.00 for Apartment. Lessons learned from this campaign included effectiveness of specific ads in ethnic markets, impact on SF-MUH work plan policy objectives, and the need for collaborations among state and local partners throughout the message development process.

HIV diagnoses and testing patterns among young gay, bisexual and other men who have sex with men: an analysis of HIV surveillance data in British Columbia, 2008-2015.

BACKGROUND: We examined changes in HIV testing indicators following a recent increase in diagnoses among young gay, bisexual and other men who have sex with men (GBMSM) in BC that accompanied implementation of a provincial HIV strategy. METHOD: Surveillance and laboratory testing data were used to compare case counts and testing characteristics among GBMSM < 30 and ≥ 30 years diagnosed in 2008-2011 and 2012-2015. We tested differences in the proportion diagnosed on first testing episode, proportion diagnosed at late stage of infection and the median inter-test interval ((ITI) time in months between last negative test and first positive test) using χ2 and Wilcoxon rank-sum tests. RESULTS: In 2008-2011, 657 diagnoses were made among GBMSM: 24% among men < 30 years and 76% among men ≥ 30 years. In 2012-2015, 590 diagnoses were made: 28% among < 30 years and 28% among ≥ 30 years. Among men < 30 years, diagnoses made on first testing episode decreased (39.4% vs. 28.7% in 2012-2015; p = 0.042) and there were few late-stage diagnoses (5.1% in 2008-2011 vs. 9.1% in 2012-2015). The median ITI was 10 months in both periods. No changes were observed over time among men ≥ 30 years. However, in both periods, late-stage diagnosis was more common in men ≥ 30 years (2008-2011, 18.8%; 2012-2015, 18.6%; p < 0.01 for both). The ITI was also longer for men ≥ 30 years (2008-2011, 24.5 months; 2012-2015, 20 months; p < 0.001 for both). CONCLUSION: Testing indicators suggested better testing practices among GBMSM diagnosed at < 30 years compared to those diagnosed at older ages. However, there are clear needs for additional prevention measures in both age groups.

Effect of opioid-substitution therapy and mental health counseling on HIV risk among hepatitis C-infected individuals.

BACKGROUND: 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. PATIENTS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.

BACKGROUND: 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. METHODS: 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+. RESULTS: 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. CONCLUSIONS: 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.

Sex, race/ethnicity, and romantic attractions: multiple minority status adolescents and mental health.

This study examined the association between multiple minority statuses and reports of suicidal thoughts, depression, and self-esteem among adolescents. Data from the National Longitudinal Study of Adolescent Health were used to examine mental health outcomes across racial/ethnic groups for same-sex-attracted youths and female youths. Hispanic/Latino, African American, and White female adolescents reported more suicidal thoughts, higher depression, and lower self-esteem compared with male adolescents in their racial/ethnic group. Same-sex-attracted youths did not consistently demonstrate compromised mental health across racial/ethnic groups. Follow-up analyses show that White same-sex-attracted female adolescents reported the most compromised mental health compared with other White adolescents. However, similar trends were not found for racial/ethnic minority female youths with same-sex attractions.

Process monitoring of an HIV treatment as prevention program in British Columbia, Canada.

BACKGROUND: In light of accumulated scientific evidence of the secondary preventive benefits of antiretroviral therapy, a growing number of jurisdictions worldwide have formally started to implement HIV Treatment as Prevention (TasP) programs. To date, no gold standard for TasP program monitoring has been described. Here, we describe the design and methods applied to TasP program process monitoring in British Columbia (BC), Canada. METHODS: Monitoring indicators were selected through a collaborative and iterative process by an interdisciplinary team including representatives from all 5 regional health authorities, the BC Centre for Disease Control (BCCDC), and the BC Centre for Excellence in HIV/AIDS (BC-CfE). An initial set of 36 proposed indicators were considered for inclusion. These were ranked on the basis of 8 criteria: data quality, validity, scientific evidence, informative power of the indicator, feasibility, confidentiality, accuracy, and administrative requirement. The consolidated list of indicators was included in the final monitoring report, which was executed using linked population-level data. RESULTS: A total of 13 monitoring indicators were included in the BC TasP Monitoring Report. Where appropriate, indicators were stratified by subgroups of interest, including HIV risk group and demographic characteristics. Six Monitoring Reports are generated quarterly: 1 for each of the regional health authorities and a consolidated provincial report. CONCLUSIONS: We have developed a comprehensive TasP process monitoring strategy using evidence-based HIV indicators derived from linked population-level data. Standardized longitudinal monitoring of TasP program initiatives is essential to optimize individual and public health outcomes and to enhance program efficiencies.

Adolescent romance and emotional health in the United States: beyond binaries.

Research on adolescent same-sex sexuality has focused almost exclusively on risk in the lives of self-identified lesbians, gays, and bisexuals. The attention to same-sex self identity may obscure heterogeneity in same-sex romance (attractions and relationships) and thus may inaccurately characterize sexual-minority youth as more different than heterosexual youth in terms of emotional health risk. Using data from the National Longitudinal Study of Adolescent Health, we examine the nexus of romantic attractions and relationships among contemporary U.S. adolescents, linking experiences of romance to indicators of emotional health. We conclude that broadening the scope of inquiry beyond binaries of identity (that is, gay vs. straight) provides the opportunity to more fully understand the health and well-being of all adolescents.
