Evaluating the impact of the COVID-19 related public health restrictions on access to digital sexually transmitted and blood borne infection testing in British Columbia, Canada: An interrupted time series analysis.

BACKGROUND: Evidence of long-term impacts of COVID-19 related public health restrictions on digital sexually transmitted and blood borne infection (STBBI) testing utilization is limited. We assessed these impacts on GetCheckedOnline (a digital testing resource for STBBIs) relative to all STBBI tests in British Columbia (BC). METHODS: Interrupted time series analyses were conducted using GetCheckedOnline program data comparing monthly test episodes (STBBI tests per requisition) among BC residents, stratified by BC region, testers' sociodemographic and sexual risk profiles, for the pre-pandemic (March 2018-February 2020) and pandemic periods (March 2020-October 2021). Trends in GetCheckedOnline testing per 100 STBBI tests in BC regions with GetCheckedOnline were analysed. Each outcome was modelled using segmented generalized least squared regression. RESULTS: Overall, 17,215 and 22,646 test episodes were conducted in the pre-pandemic and pandemic periods. Monthly GetCheckedOnline test episodes reduced immediately after restrictions. By October 2021(end of pandemic period), monthly GetCheckedOnline testing increased 21.24 test episodes per million BC residents (95%CI: -11.88, 54.84) and GetCheckedOnline tests per 100 tests in corresponding BC regions increased 1.10 (95%CI: 0.02, 2.17) above baseline trends. After initial increases among users at higher STBBI risk (symptomatic testers/testers reporting sexual contacts with STBBIs), testing decreased below baseline trends later in the pandemic, while monthly GetCheckedOnline testing increased among people ≥40 years, men who have sex with men, racialized minorities, and first-time testers via GetCheckedOnline. CONCLUSIONS: Sustained increases in utilization of digital STBBI testing during the pandemic suggest fundamental changes in STBBI testing in BC, highlighting the need for accessible and appropriate digital testing, especially for those most affected by STBBIs.

Examining the impacts of a syphilis awareness campaign among gay, bisexual, and other men who have sex with men (gbMSM) in British Columbia, Canada.

OBJECTIVES: Syphilis rates have increased in BC and disproportionately affect gay, bisexual, and other men who have sex with men (gbMSM). A social marketing campaign (Syphistory) ran from January to September 2017 with the primary goal of increasing syphilis knowledge and a secondary goal of increasing syphilis screening among gbMSM in BC. METHODS: We used pre- and post-campaign surveys to assess changes in syphilis knowledge from a convenience sample of clients attending STI clinics using one-sided t-tests. We used online Piwik metrics to examine the campaign reach, and provincial testing data to examine trends in syphilis screening. We used data from the Engage Study to examine factors associated with campaign awareness and associations with syphilis testing. RESULTS: Of the 2155 visitors to the Syphistory website with known geography, 79.4% were from BC. Moreover, STI clinic participants who saw the campaign demonstrated a greater knowledge of syphilis (9.7/12, 80.8%) than those who did not see the campaign (mean 8.9/12, 74%) (p < 0.001). Provincial syphilis testing rates were 8764 and 9749 in the 12 months before and after the campaign; however, we did not find an overall trend in testing before versus after the campaign (p = 0.147). Among Engage participants, 12.7% reported seeing the campaign and we found an association between campaign exposure and recent syphilis testing (aOR = 2.73; 95% CI = 1.51, 4.93). CONCLUSION: gbMSM who saw the campaign were more likely to report being tested for syphilis in the previous 6 months. STI clinic attendees who reported seeing the campaign also had higher syphilis knowledge compared to those who did not.

RéSUMé: OBJECTIFS: Les taux de syphilis ont augmenté en Colombie-Britannique et affectent de manière disproportionnée les hommes gais, bisexuels et autres hommes ayant des relations sexuelles avec des hommes (gbHARSAH). Une campagne de marketing social (Syphistory) a été mené de janvier à septembre 2017 avec pour objectif principal d'informer sur la syphilis et pour objectif secondaire d'augmenter le dépistage de la syphilis chez les gbHARSAH en Colombie-Britannique. MéTHODES: Nous avons réalisé deux sondages, l'un avant et l'autre après la campagne, sur un échantillon de convenance constitué de patients fréquentant des cliniques ITS, pour évaluer les changements dans les connaissances sur la syphilis à l'aide de tests t unilatéraux. Nous avons utilisé les mesures Piwik en ligne pour examiner la portée de la campagne et les données provinciales sur les tests pour examiner les tendances quant au dépistage de la syphilis. Nous avons utilisé les données de l'étude Engage à Vancouver, pour identifier les facteurs associés à la sensibilisation lors de la campagne et les associations avec le dépistage de la syphilis. RéSULTATS: Sur les 2 155 visiteurs du site Web Syphistory dont la position géographique était connue, 79,4 % provenaient de la Colombie-Britannique. De plus, les participants aux cliniques ITS ayant vu la campagne ont démontré une meilleure connaissance de la syphilis (9,7/12, 80,8 %) par rapport à ceux n'ayant pas vu la campagne (moyenne 8,9/12, 74 %) (p<0,001). Les taux provinciaux de dépistage de la syphilis étaient de 8 764 et 9 749 au cours des 12 mois précédant et suivant la campagne; cependant, nous n'avons pas trouvé de tendance globale à la hausse des dépistages suite à la campagne (p=0,147). Parmi les participants Engage, 12,7 % ont déclaré avoir vu la campagne en ligne et nous avons trouvé une association entre l'exposition à la campagne et le dépistage récent de la syphilis (RCa=2,73; IC à 95 %=1,51, 4,93). CONCLUSION: Les gbHARSAH qui ont vu la campagne étaient plus susceptibles de déclarer avoir été testés pour la syphilis au cours des six derniers mois. Les participants aux cliniques ITS qui ont déclaré avoir vu la campagne avaient également une meilleure connaissance de la syphilis que ceux qui ne l'ont pas vue.

Effectiveness of COVID-19 Vaccines in People Living with HIV in British Columbia and comparisons with a matched HIV-Negative Cohort: A Test Negative Design.

BACKGROUND: We estimated the effectiveness of COVID-19 vaccines against laboratory-confirmed SARS-CoV-2 infection among people living with HIV (PLWH) and compared estimates with a matched HIV-negative cohort. METHOD: We used the British Columbia COVID-19 Cohort, a population-based data platform which integrates COVID-19 data on SARS-CoV-2 tests, laboratory-confirmed cases, and immunizations with provincial health services data. Vaccine effectiveness (VE) was estimated with a test-negative design using multivariable logistic regression. RESULTS: Adjusted VE against SARS-CoV-2 infection was 79.2% (52.5, 90.9%) 7-59 days after two doses, rising to 91.6% (75.2, 97.2%) between 60-89 days. VE was preserved four to six months following receipt of 2 doses after which slight waning was observed (72.7% [39.1, 87.8%]). In the matched cohort (n=375 043), VE peaked at 91.0% (90.5, 91.5%) 7-59 days after 2 doses and was sustained for up to four months after which evidence of waning was observed, dropping to 83.8% (82.9, 84.7%) between four to six months. CONCLUSION: Receipt of two COVID-19 vaccines doses was effective against SARS-CoV-2 infection among PLWH pre-Omicron. VE estimates appeared to peak later in PLWH compared to the matched HIV-negative cohort and the degree of waning was relatively quicker in PLWH; however, overall estimates were comparable in both populations.

Increases in human papillomavirus vaccine coverage over 12 months among a community-recruited cohort of gay, bisexual, and other men who have sex with men in Canada.

BACKGROUND: Starting in 2015/16, most Canadian provinces introduced publicly-funded human papillomavirus (HPV) vaccination programs for gay, bisexual, and other men who have sex with men (GBM) aged ≤ 26 years. We estimated 12-month changes in HPV vaccine coverage among community-recruited GBM from 2017 to 2021 and identified baseline factors associated with vaccine initiation (≥1 dose) or series completion (3 doses) among participants who were unvaccinated or partially vaccinated at baseline. METHODS: We recruited sexually-active GBM aged ≥ 16 years in Montreal, Toronto, and Vancouver, Canada, from 02/2017 to 08/2019 and followed them over a median of 12 months (interquartile range = 12-13 months). We calculated the proportion who initiated vaccination (≥1 dose) or completed the series (3 doses) by 12-month follow-up. Analyses were stratified by city and age-eligibility for the publicly-funded programs at baseline (≤26 years or > 26 years). We used multivariable logistic regression to identify baseline factors associated with self-reported incident vaccine initiation or series completion. RESULTS: Among 165 unvaccinated participants aged ≤ 26 years at baseline, incident vaccine initiation (≥1 dose) during follow-up was 24.1% in Montreal, 33.3% in Toronto, and 38.9% in Vancouver. Among 1,059 unvaccinated participants aged > 26 years, incident vaccine initiation was 3.4%, 8.9%, and 10.9%, respectively. Higher education and trying to access pre-exposure prophylaxis for HIV were associated with incident vaccination among those aged ≤ 26 years, while younger age, residing in Vancouver (vs. Montreal), being diagnosed with anogenital warts, having both government and private extended medical insurance, and being vaccinated against influenza were associated with incident vaccination among those aged > 26 years. CONCLUSIONS: We observed substantial gains in HPV vaccine coverage among young GBM within 5 + years of targeted program implementation, but gaps remain, particularly among older men who are ineligible for publicly-funded programs. Findings suggest the need for expanded public funding or insurance coverage for HPV vaccines.

Attitudes and Preferences Regarding Non-Clinic-Based Self-Collection for Sexually Transmitted Infection Testing Among Clinic Attendees in British Columbia, Canada.

BACKGROUND: Sexually transmitted infections (STIs) are a global epidemic; although screening programs reduce transmission, barriers, including access and stigma, hinder success. The World Health Organization highlights the ability to maintain health without the direct support of a health care provider as one form of self-care, which can be applied to STI testing. Self-care through non-clinic-based self-collection for STI testing can address barriers while providing comprehensive care. Before implementation of innovative changes to screening approaches, it is important to understand if communities who rely on in-person care will self-collect outside of the clinic setting. This study investigated willingness to use non-clinic-based self-collection for STI testing among STI clinic attendees in British Columbia, Canada. METHODS: Participants (n = 446) were recruited from STI clinics offering clinic-based self-collection for STI testing and completed a survey assessing self-care attitudes, including willingness to self-collect urine samples, throat swabs, and anogenital swabs outside of the clinic setting. Descriptive statistics, bivariable analyses, and multivariable models were conducted to investigate willingness to use non-clinic-based STI self-collection methods and associated correlates. RESULTS: This population reported high willingness to use non-clinic-based self-collection methods for STI testing (urine samples, 73%; throat swabs, 67%; anogenital swabs, 65%). Those aged 35 to 54 years compared with 15 to 34 years were more likely to be willing (adjusted odds ratio, 1.87; 95% confidence interval, 1.03-3.50); those identifying as straight/mostly straight compared with gay/lesbian were less likely to be willing (adjusted odds ratio, 0.39; 95% confidence interval, 0.23-0.65). CONCLUSIONS: Non-clinic-based self-collection for STI testing can address barriers to testing while maintaining quality care. Those currently receiving in-person care find these methods highly acceptable. These findings reinforce that self-collection for STI testing used in British Columbia clinics is acceptable to clients and may be extended to collection performed outside of the clinical setting.

Accessing needed sexual health services during the COVID-19 pandemic in British Columbia, Canada: a survey of sexual health service clients.

OBJECTIVES: We assessed COVID-19 pandemic impacts on accessing needed sexual health services, and acceptability of alternative service delivery models, among sexual health service clients in British Columbia (BC), Canada. METHODS: We administered an online survey on 21 July-4 August 2020 to clients using a provincial STI clinic or internet-based testing service, GetCheckedOnline, in the year prior to March 2020. We used logistic regression to identify factors associated with having unmet sexual health needs (ie, not accessing needed services) during March-July 2020 and the likelihood of using various alternative service models, if available. RESULTS: Of 1198 survey respondents, 706 (59%) reported needing any sexual health service since March 2020; of these 706, 365 (52%) did not access needed services and 458 (66%) had avoided or delayed accessing services. GetCheckedOnline users (univariate OR (uOR)=0.62; 95% CI 0.43 to 0.88) or clients with more urgent needs (eg, treatment for new STI, uOR 0.40 (95% CI 0.21 to 0.7)) had lower odds of unmet sexual health needs. The most common factors reported for avoiding or delaying access were public messaging against seeking non-urgent healthcare (234/662, 35%), concern about getting COVID-19 while at (214/662, 32%) or travelling to (147/662, 22%) a clinic or lab and closure of usual place of accessing services (178/662, 27%). All factors were positively associated with having unmet sexual health needs, with public messaging showing the strongest effect (adjusted OR=4.27 (95% CI 2.88 to 6.42)). Likelihood of using alternative sexual health service models was high overall, with the most appealing options being home self-collection kits (634/706, 90%), receiving test kits or antibiotics at home (592/700, 85%) and express testing (565/706, 80%). CONCLUSIONS: Of BC sexual health service clients needing services during March-July 2020, many had unmet needs. Offering alternative service delivery methods may help to improve access during and beyond the COVID-19 pandemic.

Partner number and use of COVID-19 risk reduction strategies during initial phases of the pandemic in British Columbia, Canada: a survey of sexual health service clients.

OBJECTIVES: Initial public health guidance related to sex and COVID-19 infection focused on reducing partner number. We characterized individuals having a higher partner number during the initial phases of the pandemic. METHODS: In British Columbia, the initial wave of COVID-19 cases was from March 14 to May 19, 2020, followed by gradual lifting of public health restrictions. We conducted an e-mail survey of existing sexual health service clients during the period of July 23 to August 4, 2020. We used bivariate logistic regression to examine the association between the reported number of sexual partners since the start of the pandemic and key variables (level of significance p < 0.01). RESULTS: Of the 1196 clients in our final sample, 42% reported 2+ partners since the start of the pandemic, with higher odds among participants who were men who have sex with men, and single or in open relationships prior to the pandemic. This group was more likely to perceive stigma associated with having sex during the pandemic, and had the highest use of strategies to reduce risk of COVID-19 infection during sexual encounters (mainly focused on reducing/avoiding partners, such as masturbation, limiting sex to a "bubble", and not having sex). CONCLUSION: Sexual health service clients in BC with 2+ partners during the initial phases of BC's pandemic used strategies to reduce their risk of COVID-19 infection during sex. Our study provides support for a harm reduction approach to guidance on COVID-19 risk during sex, and highlights the need for further research on stigma related to having sex during the COVID-19 pandemic.

RéSUMé: OBJECTIFS: Les premières directives de santé publique sur les rapports sexuels et l'infection par la COVID-19 portaient sur la réduction du nombre de partenaires. Nous avons caractérisé les personnes ayant eu de nombreux partenaires au cours des phases initiales de la pandémie. MéTHODE: En Colombie-Britannique, la première vague de cas de COVID-19 a déferlé du 14 mars au 19 mai 2020, puis a été suivie d'une levée progressive des restrictions sanitaires. Nous avons administré un sondage par courriel auprès d'usagers existants des services de santé sexuelle entre le 23 juillet et le 4 août 2020. Nous avons procédé par régression logistique bivariée pour examiner l'association entre le nombre déclaré de partenaires sexuels depuis le début de la pandémie et certaines variables clés (seuil de signification p < 0,01). RéSULTATS: Sur les 1196 usagers de notre échantillon final, 42 % ont dit avoir eu 2 partenaires ou plus depuis le début de la pandémie, avec une probabilité plus élevée chez les participants qui étaient des hommes ayant des relations sexuelles avec des hommes et ceux qui étaient célibataires ou dans une relation ouverte avant la pandémie. Ce groupe était plus susceptible de percevoir une stigmatisation des relations sexuelles durant la pandémie, et il a présenté l'utilisation la plus élevée de stratégies pour réduire le risque de contracter la COVID-19 lors de rapports sexuels (principalement en réduisant partiellement ou à zéro le nombre de partenaires, p. ex. en se masturbant, en limitant ses partenaires aux membres de sa « bulle¼ ou en s'abstenant de tout rapport sexuel). CONCLUSION: Les usagers des services de santé sexuelle de la Colombie-Britannique ayant eu 2 partenaires ou plus durant les premières phases de la pandémie dans la province ont employé des stratégies pour réduire leur risque de contracter la COVID-19 durant les rapports sexuels. Notre étude confirme la validité d'une approche de réduction des méfaits dans les directives sur le risque de contracter la COVID-19 durant les rapports sexuels et souligne le besoin de pousser la recherche sur la stigmatisation des rapports sexuels durant la pandémie de COVID-19.

Self-rated mental health among sexual health service clients during the first months of the COVID-19 pandemic, British Columbia, Canada.

We investigated self-reported mental health during the first three months of the COVID-19 pandemic (March-May 2020), using a survey of HIV-testing and sexual health service clients from British Columbia, Canada (N = 1198). Over half (55%) reported their mental health as poor at the beginning of the COVID-19 pandemic, more than double that of the general Canadian population in the same time frame (22%). Acknowledging that this burden of poor mental health that is likely to persist in the coming years, we propose that sexual health clinics should facilitate access to mental health supports as a low-barrier point of primary care contact.
