Get Checked… Where? The Development of a Comprehensive, Integrated Internet-Based Testing Program for Sexually Transmitted and Blood-Borne Infections in British Columbia, Canada

Reach of GetCheckedOnline among gay, bisexual, transgender and queer men and Two-Spirit people and correlates of use 5 years after program launch in British Columbia, Canada

OBJECTIVES

Understanding who uses internet-based sexually transmitted and blood-borne infection (STBBI) services can inform programme implementation, particularly among those most impacted by STBBIs, including gender and sexual minority (GSM) men. GetCheckedOnline, an internet-based STBBI testing service in British Columbia, Canada, launched in 2014. Our objectives were to assess reach, identify factors associated with use of GetCheckedOnline 5 years into implementation and describe reasons for using and not using GetCheckedOnline among GSM men.

METHODS

The Sex Now 2019 Survey was an online, cross-sectional survey of GSM men in Canada administered from November 2019 to February 2020. Participants were asked a subset of questions related to use of GetCheckedOnline. Multivariable binary logistic regression modelling was used to estimate associations between correlates and use of GetCheckedOnline.

RESULTS

Of 431 British Columbia (BC) participants aware of GetCheckedOnline, 27.6% had tested using the service. Lower odds of having used GetCheckedOnline were found among participants with non-white race/ethnicity (adjusted OR (aOR)=0.41 (95% CI 0.21 to 0.74)) and those living with HIV (aOR=0.23 (95% CI 0.05 to 0.76)). Those who usually tested at a walk-in clinic, relative to a sexual health clinic, had greater odds of using GetCheckedOnline (aOR=3.91 (95% CI 1.36 to 11.61)). The most commonly reported reason for using and not using GetCheckedOnline was convenience (78%) and only accessing the website to see how the service worked (48%), respectively.

CONCLUSION

Over a quarter of GSM men in BC aware of GetCheckedOnline had used it. Findings demonstrate the importance of social/structural factors related to use of GetCheckedOnline. Service promotion strategies could highlight its convenience and privacy benefits to enhance uptake.

Moving Toward Online-Based Sexually Transmitted Infection Testing and Treatment Services for Young People: Who Will Use It and What Do They Want?

BACKGROUND

The market for online sexually transmitted infection (STI) services is rapidly expanding. Online health services often have unequal uptake among different demographics of the population. There is a need to understand how different online delivery options for STI testing may appeal to different groups of young people, particularly young people who have higher rates of STI diagnoses.

METHODS

An online survey of young Australians aged 16 to 29 years was conducted to understand service preferences regarding consultation (telehealth, fully automated questionnaire), testing (electronic pathology form, at-home self-sampling), and treatment (e-prescriptions, mailed oral tablets). Multivariable multinomial logistic regression examined associations between user characteristics and service preferences, and adjusted relative risk ratios (aRRRs) and 95% confidence intervals (CIs) are presented.

RESULTS

Among 905 respondents, rural youth were more likely to prefer fully automated questionnaires (aRRR, 1.9; 95% CI, 1.0-3.5) over telehealth consultations, whereas culturally and linguistically diverse (CALD) youth were less likely (aRRR, 0.4; 95% CI, 0.2-0.7). Rural youth preferred at-home self-sampling kits (aRRR, 1.9; 95% CI, 1.3-2.7) over electronic forms for on-site collection at pathology centers, with the opposite for CALD youth (aRRR, 0.7; 95% CI, 0.5-1.0). Receiving oral antibiotics by mail was preferred by rural youth (aRRR, 2.3; 95% CI, 1.1-4.6) over for in-clinic treatment, but not for CALD youth (aRRR, 0.5; 95% CI, 0.4-0.8).

CONCLUSIONS

Our findings suggest that rural youth tend to prefer self-navigated and automated options, whereas CALD prefer options with greater provider engagement. Online STI service providers should consider how different service options may affect equitable uptake across the population and implications for addressing disparities in testing and treatment.

Feasibility and Acceptability of a Mobile Technology Intervention to Support Postabortion Care After Surgical Abortion (the FACTS Study Phase 3): Mixed Methods Prospective Pilot Study

BACKGROUND

In Canada, 1 in 3 women and people of gestational age undergo an abortion in their lifetime. Despite the liberal legal context, barriers continue to exist for women and people who can become pregnant to access this service.

OBJECTIVE

This study aims to (1) conduct a pilot study to demonstrate the feasibility and acceptability of myPostCare to support follow-up care after a procedural abortion; (2) use the findings to understand whether myPostCare has the potential to improve contraceptive behavior and knowledge, emotional well-being, and sexual health knowledge; and (3) develop a better understanding of how innovative mobile solutions can support integrative health programs in British Columbia with the goal of expanding to other sites across Canada.

METHODS

People of gestational age (aged 14-45 y) who underwent a procedural abortion were recruited from 2 urban abortion facilities in British Columbia. The participants completed a baseline quantitative survey and were provided access to myPostCare for up to 30 days. A follow-up quantitative survey was sent via email on day 30. Qualitative interviews were conducted to explore user satisfaction and usability of myPostCare. Responses to the survey questions were summarized using descriptive statistics, and the system usability scale (SUS) was scored according to the instructions. A secure analytics platform was implemented to obtain data on the overall use of the website by users. Qualitative analysis was conducted with NVivo using a thematic analysis approach. This study was approved by the Women's and Children's Research Ethics Board.

RESULTS

Overall, 62 participants were recruited (average age 30 y); 40% (25/62) of the participants completed the exit surveys, and 24% (6/25) consented to participate in the semistructured interviews; 40 participants had undergone an immediate postabortion intrauterine device (IUD) insertion, and 22 did not have an IUD inserted. Participants were satisfied with myPostCare. The SUS average score was 81.5 (SD 9.7; median 82.5, IQR 77.5-87.5), indicating high usability of the tool. Overall, 88% (22/25) of the participants changed their contraceptive method to an IUD. Web-based analytics demonstrated that there were 61 unique visitors to the site, and the top pages visited were Postprocedure Care, Emotional Well-Being, and Contraception Explorer. The longest time spent on the website was 56 minutes. The overall email open rate was 80%, with a click rate of 36%.

CONCLUSIONS

This study demonstrates that communities and individuals are important collaborators in developing a mobile innovation that facilitates access to high-quality patient-centered abortion care. Through the cocreation process, a digital platform such as myPostCare highlighted a gap in abortion care in Canada, particularly around follow-up support after a procedural abortion.

Differential uptake and effects of digital sexually transmitted and bloodborne infection testing interventions among equity-seeking groups: a scoping review

BACKGROUND

Digital sexually transmitted and bloodborne infection (STBBI) testing interventions have gained popularity. However, evidence of their health equity effects remains sparse. We conducted a review of the health equity effects of these interventions on uptake of STBBI testing and explored design and implementation factors contributing to reported effects.

METHODS

We followed Arksey and O'Malley's framework for scoping reviews (2005) integrating adaptations by Levac et al (2010). We searched OVID Medline, Embase, CINAHL, Scopus, Web of Science, Google Scholar and health agency websites for peer-reviewed articles and grey literature comparing uptake of digital STBBI testing with in-person models and/or comparing uptake of digital STBBI testing among sociodemographic strata, published in English between 2010 and 2022. We extracted data using the Place of residence, Race, Occupation, Gender/Sex, Religion, Education, Socioeconomic status (SES), Social capital and other disadvantaged characteristics (PROGRESS-Plus) framework, reporting differences in uptake of digital STBBI testing by these characteristics.

RESULTS

We included 27 articles from 7914 titles and abstracts. Among these, 20 of 27 (74.1%) were observational studies, 23 of 27 (85.2%) described web-based interventions and 18 of 27 (66.7%) involved postal-based self-sample collection. Only three articles compared uptake of digital STBBI testing with in-person models stratified by PROGRESS-Plus factors. While most studies demonstrated increased uptake of digital STBBI testing across sociodemographic strata, uptake was higher among women, white people with higher SES, urban residents and heterosexual people. Co-design, representative user recruitment, and emphasis on privacy and security were highlighted as factors contributing to health equity in these interventions.

CONCLUSION

Evidence of health equity effects of digital STBBI testing remains limited. While digital STBBI testing interventions increase testing across sociodemographic strata, increases are lower among historically disadvantaged populations with higher prevalence of STBBIs. Findings challenge assumptions about the inherent equity of digital STBBI testing interventions, emphasising the need to prioritise health equity in their design and evaluation.

Web-Based STI/HIV Testing Services Available for Access in Australia: Systematic Search and Analysis

BACKGROUND

Sexually transmitted infection (STI) rates continue to rise in Australia, and timely access to testing and treatment is crucial to reduce transmission. Web-based services have been viewed as a way to improve timely access to STI/HIV testing and have proliferated in recent years. However, the regulation of these services in Australia is minimal, leading to concerns about their quality. The purpose of this review was to systematically identify web-based STI/HIV testing services available in Australia and assess them on aspects of quality, reliability, and accessibility.

OBJECTIVE

We aim to systematically identify and assess web-based STI/HIV testing services available in Australia.

METHODS

A Google search of Australian web-based services was conducted in March 2022 and repeated in September 2022 using Boolean operators and search terms related to test services (eg, on the internet or home), STIs (eg, chlamydia or gonorrhea), and test type (eg, self-test). The first 10 pages were assessed, and services were categorized as self-testing (ST; test at home), self-sampling (SS; sample at home and return to laboratory), or self-navigated pathology (SNP; specimens collected at pathology center). Website reliability was assessed against the Health on the Net Foundation code of conduct, and service quality was assessed using a scorecard that was developed based on similar reviews, Australian guidelines for in-person services, and UK standards. Additionally, we looked at measures of accessibility including cost, rural access, and time to test results.

RESULTS

Seventeen services were identified (8 ST, 2 SS, and 7 SNP). Only 4 services offered recommended testing for all 4 infections (chlamydia, gonorrhea, syphilis, and HIV) including genital, anorectal, and oropharyngeal sites, and 5 offered tests other than those recommended by Australian testing guidelines (eg, Ureaplasma). Nine services (1 SNP, 8 self-test) had no minimum age requirements for access. Reliability scores (scale 0-8) were similar between all services (range 4.75-8.0). Quality weighted scores (scale 0-58) were similar between SNP and SS services (average 44.89, SD 5.56 and 44.75, SD 1.77, respectively) but lower for ST services (22.66, SD 8.93; P=.002). Government-funded services were of higher quality than private services (43.54, SD 6.71 vs 29.43, SD 13.55; P=.03). The cost for services varied between SNP (Aus $0-$595; ie, US $0-$381.96), self-sample (Aus $0; ie, US $0), and ST (Aus $0-$135; ie, US $0-$86.66). The time to test results was much shorter for SNP services (~4 days) than for SS (~12 days) and ST (~14 days).

CONCLUSIONS

This review identified considerable variability in the quality and reliability of the web-based STI/HIV testing services in Australia. Given the proliferation and use of these services will likely increase, it is imperative that Australia develops national standards to ensure the standard-of-care offered by web-based STI/HIV testing services is appropriate to protect Australian users from the impact of poorly performing and inappropriate tests.

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, and testers' sociodemographic and sexual risk profiles, for the prepandemic (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 analyzed. Each outcome was modeled using segmented generalized least squared regression.

RESULTS

Overall, 17,215 and 22,646 test episodes were conducted in the prepandemic and pandemic periods. Monthly GetCheckedOnline test episodes reduced immediately after restrictions. By October 2021 (end of the pandemic period), monthly GetCheckedOnline testing increased by 21.24 test episodes per million BC residents (95% confidence interval, -11.88 to 54.84), and GetCheckedOnline tests per 100 tests in corresponding BC regions increased by 1.10 (95% confidence interval, 0.02 to 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, whereas monthly GetCheckedOnline testing increased among people 40 years or older, 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.

Treatment and Partner Notification Outcomes for Clients Diagnosed With Chlamydia and Gonorrhea Through GetCheckedOnline Compared With Sexually Transmitted Infection Clinics in British Columbia, Canada

A study comparing treatment and partner notification outcomes for people diagnosed with chlamydia or gonorrhea found no differences between clients of Internet-based and clinic-based testing services.

Background

Whether treatment, engagement in partner notification (PN), and PN outcomes differ between clients of Internet-based and clinic-based testing services is poorly understood. We compared these outcomes between people diagnosed with chlamydia and/or gonorrhea (CT/GC) through a sexually transmitted infection (STI) clinic service and GetCheckedOnline (GCO), an Internet-based testing service in British Columbia.

Methods

We conducted a retrospective matched cohort study among CT/GC cases where each case diagnosed through GCO in 2016 to 2017 was matched to 2 STI clinic cases by diagnosis, sex, age group, and specimen collection date. Data were collected through chart review, with outcomes compared using appropriate statistical tests.

Results

Of 257 GCO and 514 matched clinic cases, case treatment was high and did not differ between GCO (254 of 257 [98.9%]) and clinic (513 of 514 [99.8%]) cases, as was engagement in PN (250 of 257 [97.2%] vs. 496 of 514 [96.5%]). There was no difference in the proportion of notified partners between GCO (159 of 270 [58.9%]) and clinic (253 of 435 [58.2%]) cases, although a greater proportion of partners reported by clinic cases were notified by STI nurses (43 of 435 [9.9%]) versus GCO cases (6 of 270 [2.2%]).

Conclusions

GetCheckedOnline clients diagnosed with CT/GC demonstrated similar treatment uptake and engagement in PN to clinic clients, and PN outcomes did not differ. The greater reliance on STI clinic nurses for PN among clinic clients may be related to having had an initial in-person testing visit.

Estimating the test-adjusted incidence of Chlamydia trachomatis infections identified through Public Health Ontario Laboratories in Peel region, Ontario, 2010-2018: a population-based study

BACKGROUND

Public health guidelines for chlamydia testing are not sex specific, but young females test at a disproportionally higher rate than males and other age groups. This study aims to describe testing trends across age and sex subgroups, then estimate a test-adjusted incidence of chlamydia in these subgroups to identify gaps in current testing practices.

METHODS

We used a population-based study to examine observed chlamydia rates by age and sex subgroups: 15-19 years, 20-29 years, 30-39 years and older than 40 years. The study included diagnostic test results recorded by Public Health Ontario Laboratories between Jan. 1, 2010, and Dec. 31, 2018, for individuals living in Peel region, Ontario. We then employed meta-regression models as a method of standardization to estimate the effect of sex and age on standardized morbidity ratio, testing ratio and test positivity, then calculate a test-adjusted incidence of chlamydia for each subgroup.

RESULTS

Over the study period, infection, testing and test positivity varied across age and sex subgroups. Observed incidence and testing were highest in females aged 20-29 years, whereas males had the highest standardized test positivity across all age groups. After estimating test-adjusted incidence for each age-sex subgroup, males in the 15-19-year and 30-39-year age groups had an increase in incidence of 60.2% and 9.7%, respectively, compared with the observed incidence.

INTERPRETATION

We found that estimated test-adjusted incidence was higher than observed incidence in males aged 15-19 years and 30-39 years. This suggests that infections in males are likely being missed owing to differential testing, and this may be contributing to the persistent increase in reported cases in Canada. Public health programming that targets males, especially in high-risk settings and communities, and use of innovative partner notification methods could be critical to curbing overall rates of chlamydia.

Methods for Human-Centered eHealth Development: Narrative Scoping Review

Background

Thorough holistic development of eHealth can contribute to a good fit among the technology, its users, and the context. However, despite the availability of frameworks, not much is known about specific research activities for different aims, phases, and settings. This results in researchers having to reinvent the wheel. Consequently, there is a need to synthesize existing knowledge on research activities for participatory eHealth development processes.

Objective

The 3 main goals of this review are to create an overview of the development strategies used in studies based on the CeHRes (Center for eHealth Research) Roadmap, create an overview of the goals for which these methods can be used, and provide insight into the lessons learned about these methods.

Methods

We included eHealth development studies that were based on the phases and/or principles of the CeHRes Roadmap. This framework was selected because of its focus on participatory, iterative eHealth design in context and to limit the scope of this review. Data were extracted about the type of strategy used, rationale for using the strategy, research questions, and reported information on lessons learned. The most frequently mentioned lessons learned were summarized using a narrative, inductive approach.

Results

In the included 160 papers, a distinction was made between overarching development methods (n=10) and products (n=7). Methods are used to gather new data, whereas products can be used to synthesize previously collected data and support the collection of new data. The identified methods were focus groups, interviews, questionnaires, usability tests, literature studies, desk research, log data analyses, card sorting, Delphi studies, and experience sampling. The identified products were prototypes, requirements, stakeholder maps, values, behavior change strategies, personas, and business models. Examples of how these methods and products were applied in the development process and information about lessons learned were provided.

Conclusions

This study shows that there is a plethora of methods and products that can be used at different points in the development process and in different settings. To do justice to the complexity of eHealth development, it seems that multiple strategies should be combined. In addition, we found no evidence for an optimal single step-by-step approach to develop eHealth. Rather, researchers need to select the most suitable research methods for their research objectives, the context in which data are collected, and the characteristics of the participants. This study serves as a first step toward creating a toolkit to support researchers in applying the CeHRes Roadmap to practice. In this way, they can shape the most suitable and efficient eHealth development process.

Defining Digital Public Health and the Role of Digitization, Digitalization, and Digital Transformation: Scoping Review

Background

The recent proliferation and application of digital technologies in public health has spurred interest in digital public health. However, as yet, there appears to be a lack of conceptual clarity and consensus on its definition.

Objective

In this scoping review, we seek to assess formal and informal definitions of digital public health in the literature and to understand how these definitions have been conceptualized in relation to digitization, digitalization, and digital transformation.

Methods

We conducted a scoping literature search in Ovid MEDLINE, Embase, Google Scholar, and 14 government and intergovernmental agency websites encompassing 6 geographic regions. Among a total of 409 full articles identified, we reviewed 11 publications that either formally defined digital public health or informally described the integration of digital technologies into public health in relation to digitization, digitalization, and digital transformation, and we conducted a thematic analysis of the identified definitions.

Results

Two explicit definitions of digital public health were identified, each with divergent meanings. The first definition suggested digital public health was a reimagination of public health using new ways of working, blending established public health wisdom with new digital concepts and tools. The second definition highlighted digital public health as an asset to achieve existing public health goals. In relation to public health, digitization was used to refer to the technical process of converting analog records to digital data, digitalization referred to the integration of digital technologies into public health operations, and digital transformation was used to describe a cultural shift that pervasively integrates digital technologies and reorganizes services on the basis of the health needs of the public.

Conclusions

The definition of digital public health remains contested in the literature. Public health researchers and practitioners need to clarify these conceptual definitions to harness opportunities to integrate digital technologies into public health in a way that maximizes their potential to improve public health outcomes.

Caught between HIV exceptionalism and health service integration: Making visible the role of public health policy in the scale-up of novel sexual health services

The role of contextual factors for program implementation is well-documented; however, their changing function throughout implementation phases is less established. We conducted an institutional ethnography to understand how structural conditions for scaling up initiatives are shaped by public health policy. We conducted 25 interviews with implementers of a comprehensive sexual health testing service in Canada, 21 meeting observations, and textual analyses of key policies and reports. Our analysis revealed a disjuncture between implementers' task of scaling up programming and the actualities of working within the discursive and material confines of policies premised on HIV exceptionalism and underfunded integrated health services.

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.

Validation of a Clinical Prediction Rule to Predict Asymptomatic Chlamydia and Gonorrhea Infections Among Internet-Based Testers

BACKGROUND

Clinical prediction rules (CPRs) can be used in sexually transmitted infection (STI) testing environments to prioritize individuals at the highest risk of infection and optimize resource allocation. We previously derived a CPR to predict asymptomatic chlamydia and/or gonorrhea (CT/NG) infection among women and heterosexual men at in-person STI clinics based on 5 predictors. Population differences between clinic-based and Internet-based testers may limit the tool's application across settings. The primary objective of this study was to assess the validity, sensitivity, and overall performance of this CPR within an Internet-based testing environment (GetCheckedOnline.com).

METHODS

We analyzed GetCheckedOnline online risk assessment and laboratory data from October 2015 to June 2019. We compared the STI clinic population used for CPR derivation (data previously published) and the GetCheckedOnline validation population using χ2 tests. Calibration and discrimination were assessed using the Hosmer-Lemeshow goodness-of-fit test and the area under the receiver operating curve, respectively. Sensitivity and the fraction of total screening tests offered were quantified for CPR-predicted risk scores.

RESULTS

Asymptomatic CT/NG infection prevalence in the GetCheckedOnline population (n = 5478) was higher than in the STI clinic population (n = 10,437; 2.4% vs. 1.8%, P = 0.007). When applied to GetCheckedOnline, the CPR had reasonable calibration (Hosmer-Lemeshow, P = 0.90) and discrimination (area under the receiver operating characteristic, 0.64). By screening only individuals with total risk scores ≥4, we would detect 97% of infections and reduce screening by 14%.

CONCLUSIONS

The application of an existing CPR to detect asymptomatic CT/NG infection is valid within an Internet-based STI testing environment. Clinical prediction rules applied online can reduce unnecessary STI testing and optimize resource allocation within publicly funded health systems.

Survey of Health Care Providers' Practices and Opinions Regarding Bacterial Sexually Transmitted Infection Testing Among Gay, Bisexual, and Other Men Who Have Sex With Men

BACKGROUND

Rates of bacterial sexually transmitted infections (STIs) continue to rise among gay, bisexual, and other men who have sex with men (GBMSM) globally. Testing and treatment can prevent morbidity and transmission. However, testing rates remain suboptimal.

METHODS

In 2018, we conducted an online cross-sectional survey to explore STI testing ordering practices, 14 potential barriers for testing and 11 possible ways to improve testing from the perspective of health care providers in Toronto, Ontario. An estimated 172 providers were invited from primary care and sexual health clinic settings. Providers were eligible to complete the survey if they provided care for ≥1 GBMSM per week and were involved in the decision-making process in providing STI tests. We used descriptive statistics to summarize survey responses.

RESULTS

Ninety-five providers (55% response rate) participated, of whom 68% worked in primary care and 32% in sexual health settings. Most (66%) saw ≤10 GBMSM clients per week. In primary care (65%) and sexual health (40%) clinic settings, insufficient consultation time was the most common barrier to STI testing. In primary care, other common barriers included difficulty introducing testing during unrelated consultations (53%), forgetting (47%), and patients being sexually inactive (31%) or declining testing (27%). The following were most likely to improve testing: express/fast-track testing services (89%), provider alerts when patients are due for testing (87%), patient-collected specimens (84%), nurse-led STI testing (79%), and standing orders (79%).

CONCLUSIONS

Promising interventions to improve bacterial STI testing included initiatives that simplify and expedite testing and expand testing delivery to other health care professionals.

Awareness of and intention to use an online sexually transmitted and blood-borne infection testing service among gay and bisexual men in British Columbia, two years after implementation

Objectives

This study assessed gay, bisexual, and other men who have sex with men’s (GBMSM) awareness of and intention to use GetCheckedOnline, an online sexually transmitted and blood-borne infection (STBBI) testing service.

Methods

A cross-sectional study was conducted two years after launch among GBMSM > 18 years of age in British Columbia, Canada. Participants were recruited through community venues, clinics, websites, and apps.

Results

Of 1272 participants, 32% were aware of GetCheckedOnline. Gay identity, regularly testing at an STBBI clinic, being out to one’s healthcare provider, attending GBMSM community venues, and frequent social media use were associated with awareness. Among participants who were aware but had not used GetCheckedOnline, knowing GetCheckedOnline users, using social media, not knowing where else to test, and not wanting to see a doctor were associated with intention to use GetCheckedOnline.

Conclusion

Early promotion of GetCheckedOnline resulted in greater awareness among those connected to GBMSM.

Mapping key stakeholders' position towards interdisciplinary transgender healthcare: A stakeholder analysis

Trans individuals experience an incongruence between their sex characteristics and their gender which might cause significant distress called gender dysphoria. Gender dysphoria is commonly treated using transition-related healthcare services, like sex hormones and surgeries, ideally in interdisciplinary settings. The stakeholder environment of an interdisciplinary transgender healthcare centre (ITHC) is considered key in delivering high-quality healthcare. Therefore, a stakeholder analysis was performed seeking to improve stakeholder relationships and service quality through an evidence-based approach. Quantitative data were collected using a questionnaire administered cross-sectionally, and covering attitude towards the ITHC, influence of and influence on stakeholders, level of knowledge about the ITHC, importance of the ITHC for stakeholders and types of interests. The analysis used primary data, collected July to August 2015. N = 79 key stakeholders were identified and n = 42 (53.2%) participated in the survey. Participants were categorised analytically into four stakeholder groups: trans groups, trans health experts, healthcare system and admin departments of the ITHC. Although participants reported low values (e.g. average values on a 5-point Likert scale; importance: 2.54; influence on the ITHC: 2.43), the attitude of the four stakeholder groups towards the ITHC were positive overall. The attitudes varied, however, depending on the group, for example trans health experts and trans groups reported the highest values for most items. The results demonstrate the importance of systematically analyzing stakeholder positions in order to make appropriate policy decisions, improving stakeholder relationships and assuring long-term high-quality healthcare provision. Subsequently, an action plan was developed, focusing on the two groups with the highest values (trans health experts, trans groups). Selected measures are discussed. If stakeholders are to play their part in providing high-quality, interdisciplinary trans healthcare, they need regular information on the latest developments and recurring feedback of their interests and requirements for the ITHC.

A cohort study comparing rate of repeat testing for sexually transmitted and blood-borne infections between clients of an internet-based testing programme and of sexually transmitted infection clinics in Vancouver, Canada

OBJECTIVES

Internet-based sexually transmitted and blood-borne infection (STBBI) testing services reduce testing barriers through bypassing face-to-face clinical encounters, potentially enabling clients at ongoing sexual risk to test more frequently. To our knowledge, this hypothesis has not been previously tested. We compared the frequency of repeat testing between Vancouver-based clients of GetCheckedOnline (GCO)-an internet-based STBBI testing service in British Columbia, Canada-and clients of three sexually transmitted infection (STI) clinics in Vancouver for 29 months after GCO launched.

METHODS

An administrative data cohort (n=19 497) was assembled using GCO, clinical and laboratory databases. We included all individuals who tested for HIV, gonorrhoea/chlamydia, syphilis or hepatitis C at three STI clinics or using GCO, between September 2014 and February 2017. The rate of repeat testing (>30 days after first episode) was compared between clients who used GCO at least once and those who tested only in STI clinics. Poisson regression was used to generate relative rate (RR) for repeat testing, with adjustment for age, gender/sexual orientation, risk factors (eg, history of STI diagnosis) and rate of testing before GCO launched.

RESULTS

1093 GCO clients were identified, of whom 434 (40%) had repeat test episodes; 8200/18 404 (45%) of clinic clients tested more than once. During the 29-month analysis period, GCO clients repeat tested 1.87 times per person-year, whereas clinic clients repeat tested 1.53 times per person-year, resulting in a crude RR of 1.22 (95% CI: 1.14 to 1.31). Adjustment for covariates increased the RR to 1.26 (95% CI: 1.15 to 1.37).

CONCLUSIONS

In this cohort, individuals using internet-based STBBI testing had a rate of repeat testing 22% greater than clinic-based clients. This effect was increased after adjusting for characteristics associated with higher test frequency. The online interface of GCO may facilitate more frequent testing and may therefore contribute to earlier STBBI diagnosis.

Feasibility and Acceptability of a Mobile Technology Intervention to Support Postabortion Care (The FACTS Study Phase II) After Surgical Abortion: User-Centered Design

Background

Human-centered design is a methodology that applies an iterative participatory process that engages the end-user for whom an innovation or intervention is designed for from start to end. There is general evidence to support the use of human-centered design for development of tools to affect health behavior, but specifically for family planning provision. This study is part two of a three-phase study that uses a user-centered design methodology which uses the findings from Phase I to design, develop, and test a digital health solution to support follow-up after an induced surgical abortion.

Objective

The objectives for this study were to: (1) develop a Web-based intervention based on preferences and experiences of women who underwent an abortion as measured in the formative phase of the Feasibility and Acceptability of a Mobile Technology Intervention to Support Postabortion Care Study; (2) conduct usability testing of the intervention to determine user-friendliness and appropriateness of the intervention; and (3) finalize a beta version of the Web-based intervention for pilot testing.

Methods

The study design was based on the “development-evaluation-implementation” process from the Medical Research Council Framework for Complex Medical Interventions. This study is in Phase II of III and is based on user-centered design methodology. Phase I findings demonstrated that women engage with technology to assist in clinical care and they preferred a comprehensive website with email or text notifications to support follow-up care. In Phase II we collaborated with family planning experts and key stakeholders to synthesize evidence from Phase I. With them and a development partner we built a prototype. Usability testing was completed with 9 participants using a validated System Usability Scale. This was then used to refine the intervention for Phase III pilot study. This study was approved by the local Ethics board.

Results

We developed a comprehensive Web-based tool called myPostCare.ca, which includes: Post-Procedure Care, Emotional Well-Being Tool, Contraception Explorer, Sexual Health, Book an Appointment, and Other Resources. Additionally, over the course of a month after the procedure, automatic email notifications were sent to women as a form of virtual follow-up support, directing them to myPostCare.ca resources. The Web-based tool was refined based on usability testing results.

Conclusions

This study demonstrated that user-centered design is a useful methodology to build programs and interventions that are women-centered, specifically for abortion care.

Feasibility and Acceptability of a Mobile Technology Intervention to Support Postabortion Care in British Columbia: Phase I

Background

Over 30% of women in Canada undergo an abortion. Despite the prevalence of the procedure, stigma surrounding abortion in Canada leads to barriers for women to access this service. The vast majority of care is concentrated in urban settings. There is evidence to support utilization of innovative mobile and other technology solutions to empower women to safely and effectively self-manage aspects of the abortion process. This study is part 1 of a 3-phase study that utilizes user-centered design methodology to develop a digital health solution to specifically support follow-up after an induced surgical abortion.

Objective

This study aimed to (1) understand how women at 3 surgical abortion clinics in an urban center of British Columbia utilize their mobile phones to access health care information and (2) understand women’s preferences of content and design of an intervention that will support follow-up care after an induced abortion, including contraceptive use.

Methods

The study design was based on development-evaluation-implementation process from Medical Research Council Framework for Complex Medical Interventions. This was a mixed-methods formative study. Women (aged 14-45 years) were recruited from 3 urban abortion facilities in British Columbia who underwent an induced abortion. Adaptation of validated surveys and using the technology acceptance model and theory of reasoned action, a cross-sectional survey was designed. Interview topics included demographic information; type of wireless device used; cell phone usage; acceptable information to include in a mobile intervention to support women’s abortion care; willingness to use a mobile phone to obtain reproductive health information; optimal strategies to use a mobile intervention to support women; understand preferences for health information resources; and design qualities in a mobile intervention important for ease of use, privacy, and security. Responses to questions in the survey were summarized using descriptive statistics. Qualitative analysis was conducted with NVivo using a thematic analysis approach. This study was approved by the local ethics board.

Results

A waiting-room survey was completed by 50 participants, and semistructured interviews were completed with 8 participants. The average age of participants was 26 years. Furthermore, 94% (47/50) owned a smartphone, 85% (41/48) used their personal phones to go online, and 85% would use their cell phone to assist in clinical care. Qualitative analysis demonstrated that women prefer a comprehensive website that included secure email or text notifications to provide tools and resources for emotional well-being, contraceptive decision making, general sexual health, and postprocedure care.

Conclusions

A community-based mixed-methods approach allowed us to understand how women use their cell phones and what women desire in a mobile intervention to support their postabortion care. The findings from this formative phase will assist in the development and testing of a mobile intervention to support follow-up care after an induced surgical abortion.

Conceptualizing Geosexual Archetypes: Mapping the Sexual Travels and Egocentric Sexual Networks of Gay and Bisexual Men in Toronto, Canada

Six geosexual archetypes were identified: hosters, house-callers, rovers, privates, travellers, and geoflexibles, each with different characteristic profiles. Prioritizing interventions to hosters, rovers, and geoflexibles may reduce sexually transmitted infection transmission.

Supplemental digital content is available in the text.

Background

There are complex, synergistic, and persistent sexually transmitted infection (STI) epidemics affecting gay, bisexual and other men who have sex with men (gbMSM) in every major urban centre across North America. We explored the spatial architecture of egocentric sexual networks for gbMSM in Toronto, Canada.

Methods

Our integrative mixed methods study included in-depth interviews with 31 gbMSM between May and July 2016. During interviews, participants mapped their egocentric sexual network for the preceding 3 months geographically. At the end, a self-administered survey was used to collect sociodemographic characteristics, online technology use, and STI testing and history.

Results

We identified 6 geosexual archetypes: hosters, house-callers, privates, rovers, travellers, and geoflexibles. Hosters always, or almost always (≥80%), hosted sex at their home. House-callers always, or almost always (≥80%), had sex at their partner’s home. Rovers always or almost always (≥80%) had sex at public venues (eg, bath houses, sex clubs) and other public spaces (eg, parks, cruising sites). Privates had sex in private—their own home or their partner's (part hoster, part house-caller). Travellers had sex away from their home, either at a partner’s home or some other venue or public space (part house-caller, part rover). Geoflexibles had sex in a variety of locations—their home, their partner’s home, or public venues. All hosters and rovers, and to a lesser extent, geoflexibles, reported a history of syphilis and human immunodeficiency virus.

Conclusions

Prioritizing interventions to hosters, rovers, and geoflexibles may have an important impact on reducing STI transmission.

Post-test comparison of HIV test knowledge and changes in sexual risk behaviour between clients accessing HIV testing online versus in-clinic

OBJECTIVE

Internet-based HIV testing offers the potential to address privacy-related barriers to testing and increase frequency of testing but may result in missed opportunities related to sexual health education and prevention that typically occur in face-to-face encounters. In this study, we assessed the HIV test knowledge and sexual risk behaviour of clients testing for HIV through GetCheckedOnline, an internet-based sexually transmitted and bloodborne infection testing platform inclusive of HIV testing, in comparison to clients testing through a large sexual health clinic.

METHODS

We concurrently recruited GetCheckedOnline clients and clinic clients from Vancouver, Canada, over the course of a 10-month period during 2015-2016. Participants completed baseline and 3-month questionnaires, anonymous and online. A six-item score was used to estimate knowledge of HIV test concepts typically conveyed during an HIV pretest encounter in a clinic. We used multiple regression to estimate associations between testing modality (online vs clinic based) and two outcomes-HIV test knowledge and change in condom use pre/post-test-with adjustment for relevant background factors.

RESULTS

Among 352 participants, online testers demonstrated higher HIV post-test knowledge than clinic-based testers (mean score 4.65/6 vs 4.09/6; p<0.05); this difference was reduced in adjusted analysis (p>0.05). Men who have sex with men, clients with a university degree, those who have lived in Canada >10 years and English speakers had higher HIV post-test knowledge (p<0.05). Eighteen per cent of online testers and 10% of clinic-based testers increased condom use during the 3 months post-test (p>0.05).

CONCLUSIONS

In this comparative study between online and clinic-based testers, we found no evidence of decreased HIV test knowledge or decreased condom use following HIV testing through GetCheckedOnline. Our findings suggest that with careful design and attention to educational content, online testing services may not lead to missed opportunities for HIV education and counselling.

Assessing the Impact of a Social Marketing Campaign on Program Outcomes for Users of an Internet-Based Testing Service for Sexually Transmitted and Blood-Borne Infections: Observational Study

BACKGROUND

While social marketing (SM) campaigns can be effective in increasing testing for sexually transmitted and blood-borne infections (STBBIs), they are seldom rigorously evaluated and often rely on process measures (eg, Web-based ad click-throughs). With Web-based campaigns for internet-based health services, there is a potential to connect campaign process measures to program outcomes, permitting the assessment of venue-specific yield based on health outcomes (eg, click-throughs per test).

OBJECTIVE

This study aims to evaluate the impact of an SM campaign by the promotional venue on use and diagnostic test results of the internet-based STBBI testing service GetCheckedOnline.com (GCO).

METHODS

Through GCO, clients create an account using an access code, complete a risk assessment, print a lab form, submit specimens at a lab, and get results online or by phone. From April to August 2015, a campaign promoted GCO to gay, bisexual, and other men who have sex with men in Vancouver, Canada. The campaign highlighted GCO's convenience in 3 types of promotional venues-location advertisements in print or video displayed in gay venues or events, ads on a queer news website, and ads on geosocial websites and apps. Where feasible, individuals were tracked from campaign exposures to account creation and testing using venue-specific GCO access codes. In addition, Web-based ads were linked to alternate versions of the campaign website, which used URLs with embedded access codes to connect ad exposure to account creation. Furthermore, we examined the number of individuals creating GCO accounts, number tested, and cost per account created and test for each venue type.

RESULTS

Over 6 months, 177 people created a GCO account because of the campaign, where 22.0% (39/177) of these completed testing; the overall cost was Can $118 per account created and Can $533 per test. Ads on geosocial websites and apps accounted for 46.9% (83/177) of all accounts; ads on the news website had the lowest testing rate and highest cost per test. We observed variation between different geosocial websites and apps with some ads having high click-through rates yet low GCO account creation rates, and vice versa.

CONCLUSIONS

Developing mechanisms to track individuals from Web-based exposure to SM campaigns to outcomes of internet-based health services permits greater evaluation of the yield and cost-effectiveness of different promotional efforts. Web-based ads with high click-through rates may not have a high conversion to service use, the ultimate outcome of SM campaigns.

Qualitative analysis of the experiences of gay, bisexual and other men who have sex with men who use GetCheckedOnline.com: a comprehensive internet-based diagnostic service for HIV and other STIs

Objectives

To describe the factors that influence gay, bisexual and other men who have sex with men’s (gbMSM) experiences with GetCheckedOnline.com (GCO) in British Columbia (BC), Canada. GCO clients complete an internet-based risk assessment and print a laboratory test requisition form for HIV and other STIs to take to a private laboratory for diagnostic services.

Methods

Drawing on a purposive stratified sampling framework, we conducted 37 in-depth semistructured interviews with gbMSM who had used GCO at least once between 2015 and 2017.

Results

Participants expressed a preference for GCO (instead of clinic-based testing) because of convenience, privacy and control over specimen collection (specifically with doing one’s own throat or anal swab). Participants preferred receiving their results online via GCO compared with phone or email follow-up by clinic staff. GCO was viewed positively because it offers gbMSM living outside of urban city centres easy access to diagnostic services, including access to pooled nucleic acid amplification testing. Many participants also continued to positively view the clinic-based services available for gbMSM in their community. These services were frequently described as highly competent, tailored and comprehensive in responding to more complex needs. For example, attending a clinic was viewed as preferential to GCO in instances where there was a desire to access services addressing co-occurring health issues (eg, mental health; substance use disorders). Almost all of the participants anticipated using both GCO and clinic-based services in the future.

Conclusions

gbMSM report positive experiences and perceptions of GCO; however, they do not view GCO as a panacea. The results of this study point to the need to ensure that a wide range of integrated service options (eg, online; clinic-based) are available to address the range of sexual health needs of gbMSM living in BC's diverse settings.

Web-Based Activity Within a Sexual Health Economy: Observational Study

Background

Regular testing for sexually transmitted infections (STIs) is important to maintain sexual health. Self-sampling kits ordered online and delivered in the post may increase access, convenience, and cost-effectiveness. Sexual health economies may target limited resources more effectively by signposting users toward Web-based or face-to-face services according to clinical need.

Objective

The aim of this paper was to investigate the impact of two interventions on testing activity across a whole sexual health economy: (1) the introduction of open access Web-based STI testing services and (2) a clinic policy of triage and signpost online where users without symptoms who attended clinics for STI testing were supported to access the Web-based service instead.

Methods

Data on attendances at all specialist public sexual health providers in an inner-London area were collated into a single database. Each record included information on user demographics, service type accessed, and clinical activity provided, including test results. Clinical activity was categorized as a simple STI test (could be done in a clinic or online), a complex visit (requiring face-to-face consultation), or other.

Results

Introduction of Web-based services increased total testing activity across the whole sexual health economy by 18.47% (from 36,373 to 43,091 in the same 6-month period—2014-2015 and 2015-2016), suggesting unmet need for testing in the area. Triage and signposting shifted activity out of the clinic onto the Web-based service, with simple STI testing in the clinic decreasing from 16.90% (920/5443) to 12.25% (511/4172) of total activity, P<.001, and complex activity in the clinic increasing from 69.15% (3764/5443) to 74.86% (3123/4172) of total activity, P<.001. This intervention created a new population of online users with different demographic and clinical profiles from those who use Web-based services spontaneously. Some triage and signposted users (29.62%, 375/1266) did not complete the Web-based testing process, suggesting the potential for missed diagnoses.

Conclusions

This evaluation shows that users can effectively be transitioned from face-to-face to Web-based services and that this introduces a new population to Web-based service use and changes the focus of clinic-based activity. Further development is underway to optimize the triage and signposting process to support test completion.

Differences in experiences of barriers to STI testing between clients of the internet-based diagnostic testing service GetCheckedOnline.com and an STI clinic in Vancouver, Canada

OBJECTIVES

Internet-based STI testing programmes may overcome barriers posed by in-clinic testing, though uptake could reflect social gradients. The role these services play in comparison to clinical testing services is unknown. We compared experiences of testing barriers between STI clinic clients to clients of GetCheckedOnline.com (GCO; where clients take a printed lab form to a lab).

METHODS

Our 10-month cross-sectional study was conducted after GCO was promoted to STI clinic clients and men who have sex with men (MSM). Clinic and GCO clients completed an online survey assessing testing barriers and facilitators; responses were compared using bivariate analysis (level of significance P<0.01; significant results below).

RESULTS

Compared with 321 clinic clients, the 73 GCO clients were more likely to be older (median 35 vs 30 years), MSM (45% vs 16%), be testing routinely (67% vs 39%), have delayed testing for any reason (76% vs 54%) and due to clinic distance (28% vs 9%), report delays due to wait times (50% vs 17%), embarrassment with testing (16% vs 6%), discomfort discussing sexual health where they usually go for testing (39% vs 22%), as well as discomfort discussing sexual history with (19% vs 5%) and fearing judgement from (30% vs 15%) any healthcare provider. GCO clients were less likely to have found clinic hours convenient (59% vs 77%) and clinic appointments easy to make (49% vs 66%), and more likely to report long wait times (50% vs 17%). We found no differences in technology skills/use.

CONCLUSIONS

In this urban setting, an internet-based testing service effectively engaged individuals experiencing testing barriers, with few social gradients in uptake. While some testing barriers could be addressed through increasing access to clinical services, others require social and structural changes, highlighting the importance of internet-based STI testing services to increasing test uptake.

Anticipating the potential for positive uptake and adaptation in the implementation of a publicly funded online STBBI testing service: a qualitative analysis

Background

Online health services are a rapidly growing aspect of public health provision, including testing for sexually transmitted and other blood-borne infections (STBBI). Generally, healthcare providers, policymakers, and clients imbue online approaches with great positive potential (e.g., encouraging clients’ agency; providing cost-effective services to more clients). However, the promise of online health services may vary across contexts and be perceived in negative or ambiguous ways (e.g., risks to ‘gold standard’ care provision; loss of provider control over an intervention; uncertainty related to budget implications). This study examines attitudes and perceptions regarding the development of a novel online STBBI testing service in Vancouver, Canada. We examine the perceptions about the intervention’s potential by interviewing practitioners and planners who were engaged in the development and initial implementation of this testing service.

Methods

We conducted in-depth interviews with 37 healthcare providers, administrators, policymakers, and community-based service providers engaged in the design and launch of the new online STBBI testing service. We also conducted observations during planning and implementation meetings for the new service. Thematic analysis techniques were employed to identify codes and broader discursive themes across the interview transcripts and observation notes.

Results

Some study participants expressed concern that the potential popularity of the new testing service might increase demand on existing sexual health services or become fiscally unsustainable. However, most participants regarded the new service as having the potential to improve STBBI testing in several ways, including reducing waiting times, enhancing privacy and confidentiality, appealing to more tech-savvy sub-populations, optimizing the redistribution of demands on face-to-face service provision, and providing patient-centred technology to empower clients to seek testing.

Conclusions

Participants perceived this online STBBI testing service to have the potential to improve sexual health care provision. But, they also anticipated actions-and-reactions, revealing a need to monitor ongoing implementation dynamics. They also identified the larger, potentially system-transforming dimension of the new technology, which enables new system drivers (consumers) and reduces the amount of control health care providers have over online STBBI testing compared to conventional in-person testing.

Online-to-offline models in HIV service delivery

PURPOSE OF REVIEW

Half the world's population has access to Internet and technologies, and utilization is near-ubiquitous among providers and key populations. Despite being so well connected; identifying, reaching and linking vulnerable populations to HIV clinical services remains a global challenge. This review highlights the emerging online-to-offline (O2O) models, their potential in scaling up services, and evaluating impact, and implications for future research.

RECENT FINDINGS

Globally, four major types of O2O models have been implemented, primarily in the West and Asia, especially among MSM and transgender women. These models have varying levels of impact in terms of reach, engagement, participation, linkage, and ability to track and monitor participants, and assess outcomes. Those integrated with offline sites enable seamless transition, dramatically reduce the O2O linkage time and demonstrate high linkage success (>73%). O2O models are ideal for at-risk, stigmatized, criminalized populations and for scaling-up biomedical prevention interventions such as preexposure and postexposure prophylaxis.

SUMMARY

O2O models represent novel and powerful solutions to reverse the pandemic and could help fill significant programmatic gaps in tracking individuals through HIV cascades. Providers, especially in resource-limited settings, could choose between a variety of current approaches highlighted in this review and employ no-cost or cost-effective technologies to transform their traditional models and leverage O2O models.

Assessing association between IWantTheKit risk quiz tool and sexually transmitted infection positivity in male users for sexually transmitted infection screening

Our previous pilot study during 2010-2013, based on the IWantTheKit (IWTK) home self-collection program for sexually transmitted infections (STIs), showed that voluntary risk score tool predicted STIs well in female volunteers compared to their male counterparts. Risk score became a required part of the IWTK program in August 2013. We investigated association of IWTK risk score and presence of STI in 592 male participants living in Maryland and Washington DC from August 2013 to April 2015. The risk score quiz includes questions on demographic and sexual risk behavior. Data were analyzed using the Cochran-Armitage test for trend to determine if prevalence of STIs (Chlamydia, gonorrhea, or trichomoniasis) increased with the higher risk score category. Overall, 57% of participants were aged < 30 years (mean: 30.1 ± 9.3 years); 42% white, 42% black, and 16% other races. The majority (67%) of participants had medium risk scores of 3-6, followed by high scores of 7-10 (22%), and 0-2 (11%). The overall prevalence of STIs was 10.5% (62/592). The prevalence of STIs was 3.1% for users with risk scores of 0-2, 10.4% for those with scores 3-6, and 14.3% for those with scores 7-10 (trend test: p = 0.019). Medium and high IWTK risk scores successfully predicted the probability of STIs in male participants after elimination of potential selection biases.

Click yes to consent: Acceptability of incorporating informed consent into an internet-based testing program for sexually transmitted and blood-borne infections

BACKGROUND

Autonomous use of online health care services without interaction with a health care provider challenges existing models for achieving informed consent (IC); current examinations of this issue have focused on commercial direct-to-consumer genetic testing. As IC is integral to publicly funded clinical testing services, we incorporated pre-test concepts necessary for IC in GetCheckedOnline (GCO), British Columbia's online sexually transmitted and blood-borne infection (STBBI) testing service.

OBJECTIVE

We assessed the acceptability of this IC step and its design options among potential users during usability testing of GCO.

METHODS

English-speaking participants≥19years were recruited from Craigslist and among provincial STI clinic clients for usability testing of an early version of GCO, which included a consent webpage presenting 8 pre-test statements for review prior to completing testing. Participants were interviewed regarding their acceptability, perceptions, and understanding of the consent page; transcripts were analyzed thematically.

RESULTS

We conducted 13 interviews (9 males, 4 females; 9 self-identified as heterosexual; all had previously tested for STBBI). We identified three main themes: i) the meaning of IC (consent page viewed as important and for protection of individual and organization; participants demonstrated varying understandings of specific components); ii) the impact of previous experience on understanding IC (participants understood difference between online and in-person testing; IC concepts were better understood by participants with more testing experience); iii) the role of website design on achieving IC (design of page to disrupt speedy click-throughs was valued and demonstrated seriousness of the consent page).

CONCLUSIONS

Our careful attention to both content and design of the consent page of GCO was highly valued by potential users of the service, and effective in disrupting routinization of consent on websites. We argue that principles of IC apply equally in online self-testing programs as in clinical practice, and can be effectively achieved without detracting from the user experience.

Use of GetCheckedOnline, a Comprehensive Web-based Testing Service for Sexually Transmitted and Blood-Borne Infections

Background

The British Columbia Centre for Disease Control implemented a comprehensive Web-based testing service GetCheckedOnline (GCO) in September 2014 in Vancouver, Canada. GCO’s objectives are to increase testing for sexually transmitted and blood-borne infections (STBBIs), reach high-prevalence populations facing testing barriers, and increase clinical STI service capacity. GCO was promoted through email invitations to provincial STI clinic clients, access codes to clients unable to access immediate clinic-based testing (deferred testers), and a campaign to gay, bisexual, and other men who have sex with men (MSM).

Objective

The objective of the study was to report on characteristics of GCO users, use and test outcomes (overall and by promotional strategy) during this pilot phase.

Methods

We used GCO program data, website metrics, and provincial STI clinic records to describe temporal trends, progression through the service pathway, and demographic, risk, and testing outcomes for individuals creating GCO accounts during the first 15 months of implementation.

Results

Of 868 clients creating accounts, 318 (36.6%) submitted specimens, of whom 96 (30.2%) tested more than once and 10 (3.1%) had a positive STI diagnosis. The proportion of clients submitting specimens increased steadily over the course of the pilot phase following introduction of deferred tester codes. Clients were diverse with respect to age, gender, and ethnicity, although youth and individuals of nonwhite ethnicity were underrepresented. Of the 506 clients completing risk assessments, 215 (42.5%) were MSM, 89 (17.6%) were symptomatic, 47 (9.3%) were STI contacts, 232 (45.8%) reported condomless sex, 146 (28.9%) reported ≥4 partners in the past 3 months, and 76 (15.0%) reported a recent STI. A total of 63 (12.5%) GCO clients were testing for the first time. For 868 accounts created, 337 (38.8%) were by clinic invitations (0 diagnoses), 298 (34.3%) were by deferred testers (6 diagnoses), 194 (22.4%) were by promotional campaign (3 diagnoses), and 39 (4.5%) were by other means (1 diagnosis).

Conclusions

Our evaluation suggests that GCO is an acceptable and feasible approach to engage individuals in testing. Use by first-time testers, repeated use, and STI diagnosis of individuals unable to access immediate clinic-based testing suggest GCO may facilitate uptake of STBBI testing and earlier diagnosis. Use by MSM and individuals reporting sexual risk suggests GCO may reach populations with a higher risk of STI. Motivation to test (eg, unable to access clinical services immediately) appears a key factor underlying GCO use. These findings identify areas for refinement of the testing model, further promotion, and future research (including understanding reasons for drop-off through the service pathway and more comprehensive evaluation of effectiveness). Increased uptake and diagnosis corresponding with expansion of the service within British Columbia will permit future evaluation of this service across varying populations and settings.
