RESUMEN

INTRODUCTION: The rates of gonorrhea and chlamydia have been increasing in the years preceding the COVID19 pandemic. Because most gonorrhea and chlamydia infections are located in the oropharynx and rectum for men who have sex with men (MSM), and because at-home self-collected swabs for these infections are not licensed by Health Canada or the United States Food and Drug Administration, decreased accessed to in-person care during and since the COVID19 pandemic potentially means missed case findings. OBJECTIVES: To evaluate the performance of at-home self-collected pharyngeal and rectal swabs for gonorrhea and chlamydia nucleic acid amplification testing. METHODOLOGY: All persons who contacted our Sexual Health Clinic and who had a clinical indication to complete oral and/or rectal swabs for gonorrhea and chlamydia were invited to complete at-home swabs in advance of their scheduled appointments. We mailed swabs and instructions to those who consented. Participants brought these swabs to their scheduled in clinic appointments, where we repeated the same swabs. All matching swabs were sent to the laboratory for analysis to determine concordance. RESULTS: From September 8, 2022 to July 18, 2023, we enrolled 296 eligible participants who provided 1184 swabs. For analysis, cancelled specimens and specimens with invalid results were excluded, leaving 1032 swabs for comparison. We identified 66 STI diagnoses in 47 unique participants. Overall accuracy was high (exceeding 99%), except for rectal chlamydia, which was 96.0%. While the performance of self-swabs for chlamydia was lower compared to gonorrhea, at-home swabs identified six chlamydia infections that were missed by in-clinic collected swabs (two pharyngeal, four rectal). Removing these six cases as "false positives" increased overall accuracy for chlamydia detection to 99.7% (pharyngeal) and 97.8% (rectal). CONCLUSION: Self-collected at-home swabs had good performance acceptable for gonorrhea and chlamydia nucleic acid amplification testing.

RESUMEN

Current international HIV testing guidelines recommend that HIV negative persons from HIV priority groups complete repeat screening every 3-6 months; local guidelines in our jurisdiction recommend that such retesting should occur every 3 months. Such an approach allows for timely HIV diagnosis and linkage to care - and aligns with the UNAIDS 95-95-95 targets to have 95% of undiagnosed persons be aware of their HIV status. To meet these aims, new approaches to HIV testing have been developed, including our HIV self-testing initiative, GetaKit.ca, which uses an online screening algorithm to determine eligibility and has built in pathways for re-test reminders, linkage HIV prevention care, and rapid follow-up for positive test results. To understand self-testing frequency in relation to our local recommendations for resting every 3 months, we evaluated data from participants who ordered repeat HIV self-tests through GetaKit.ca. Descriptive analyses were performed on participant characteristics and chi-square tests were performed on aggregated participant risk data. During the study period, 5235 HIV self-tests were distributed to 3627 participants, of whom, 26% ordered more than once and 27% belonged to an HIV priority population. Participants who retested were more likely to have been white, male, and part of an HIV priority population; they were also more likely to have completed prior STI or HIV testing or had a prior STI diagnosis, compared to those who did not. We identified 16 new HIV diagnoses, 2 of which were among repeat testers. Our results suggest that HIV self-testing can be useful to help meet UNAIDS targets to identify undiagnosed infections; however, such efforts are less likely to be successful without adequate linkage to follow-up services, including HIV treatment and prevention care.

RESUMEN

BACKGROUND: In Ontario, Canada we developed and implemented an online screening algorithm for the distribution of HIV self-tests, known as GetaKit. During the COVID pandemic, we adapted the GetaKit algorithm to screen for COVID based on population and infection data and distributed COVID rt-LAMP self-tests (using the Lucira Check-It®) to eligible participants. METHODS: GetaKit/COVID was a prospective observational study that occurred over a 7-month period from September 2021 to April 2022. All potential participants completed an online registration and risk assessment, including demographic information, COVID symptoms and risk factors, and vaccination status. Bivariate comparisons were performed for three outcomes: results reporting status, vaccination status, and COVID diagnosis status. Data were analysed using Chi-Square for categorial covariates and Independent Samples T-Test and Mann-Whitney U test for continuous covariates. Bivariate logistic regression models were applied to examine associations between the covariates and outcomes. RESULTS: During the study period, we distributed 6469 COVID self-tests to 4160 eligible participants; 46% identified as Black, Indigenous or a Person of Colour (BIPOC). Nearly 70% of participants reported their COVID self-test results; 304 of which were positive. Overall, 91% also reported being vaccinated against COVID. Statistical analysis found living with five or fewer people, having tested for COVID previously, and being fully vaccinated were positive factors in results reporting. For COVID vaccination, people from large urban centers, who identified their ethnicity as white, and who reported previous COVID testing were more likely to be fully vaccinated. Finally, being identified as a contact of someone who had tested positive for COVID and the presence of COVID-related symptoms were found to be positive factors in diagnosis. CONCLUSIONS: While most participants who accessed this service were vaccinated against COVID and the majority of diagnoses were identified in participants who had symptoms of, or an exposure to, COVID, our program was able to appropriately link participants to recommended follow-up based on reported risks and results. These findings highlight the utility of online screening algorithms to provide health services, particularly for persons with historical barriers to healthcare access, such as BIPOC or lower-income groups.

RESUMEN

At the 16th International AIDS Conference in Montreal, Canada's Federal Health Minister announced that the Government of Canada will invest $17 million to increase access to HIV testing, $8 million of which would be used to purchase and distribute HIV self-tests. While HIV testing, and subsequent diagnoses, is a critical first step to achieving the updated UNAIDS goals of 95-95-95, testing on its own does not guarantee linkage to treatment or prevention services. In other words, it does not alone guarantee progress toward the 95-95-95 goals. GetaKit, Canada's first HIV self-test mail-out project, has demonstrated that a preliminary risk-assessment consistent with US CDC and PHAC screening guidelines ensures targeted uptake among communities most affected by HIV, thus minimizing the risk of false positive results and poor positive predictive values. Furthermore, HIV self-testing must link not only individuals with positive results to treatment, but also persons with negative results to pre-exposure prophylaxis (PrEP) along with re-testing as required. However, both access to treatment and PrEP remain inconsistently available across Canada. Therefore, while this one-time investment of funding to increase HIV testing is encouraging, without clear instructions as to who should be prioritized for testing and definitive next steps to ensure that individuals are successfully linked to care, Canada risks wasting resources, further exacerbating pre-existing inequities.


RéSUMé: Lors de la 16e Conférence internationale sur le sida qui s'est tenue à Montréal, le ministre fédéral de la Santé a annoncé que le gouvernement du Canada investirait 17 millions de dollars pour améliorer l'accès au dépistage du VIH, dont 8 millions pour l'achat et la distribution d'autotests de dépistage. Bien que le dépistage du VIH et les diagnostics qui en découlent constituent une première étape essentielle pour atteindre les objectifs actualisés de l'ONUSIDA (95-95-95), le dépistage en lui-même ne garantit pas l'accès à des services de traitement ou de prévention. En autres mots, il ne garantit en lui-même le progrès vers l'objectif 95-95-95. GetaKit, le premier projet canadien d'envoi postal d'autotests de dépistage du VIH, a démontré qu'une évaluation préliminaire des risques conforme aux directives de dépistage des CDC américains et de l'ASPC garantit une participation ciblée au sein des communautés les plus touchées par le VIH, minimisant ainsi le risque de résultats faussement positifs et de valeurs prédictives positives médiocres. En outre, l'autodépistage du VIH doit permettre non seulement aux personnes dont les résultats sont positifs de suivre un traitement, mais aussi aux personnes dont les résultats sont négatifs de bénéficier d'une prophylaxie pré-exposition (PrEP) et d'un nouveau test, le cas échéant. Cependant, l'accès au traitement et à la PrEP n'est pas uniformément disponible au Canada. Par conséquent, bien que cet investissement ponctuel de fonds pour augmenter le dépistage du VIH soit encourageant, en l'absence d'instructions claires sur les personnes à tester en priorité et sur les prochaines étapes à suivre pour s'assurer que les personnes sont bien dirigées vers les soins nécessaires, le Canada risque de gaspiller des ressources, ce qui ne fera qu'exacerber les inégalités déjà existantes.

RESUMEN

When analyzing the data for Ontario, Canada, HIV rates continue to be highest among gay, bisexual and other men who have sex with men (gbMSM). Since HIV diagnosis is a key component of HIV care, self-testing has provided options for allowing this population to access care, resulting in a significant number of first-time testers. Between 1 April 2021 and 31 January 2022, 882 gbMSM participants ordered an HIV self-test through GetaKit. Of these, 270 participants reported that they had never undergone HIV testing previously. Our data showed that first-time testers were generally younger, members of BIPOC (Black, Indigenous and people of color) communities and they reported more invalid test results than those who had tested previously. This suggests that HIV self-testing may be a more successful and appealing component of the HIV prevention armamentarium for this population, but one that is not without its shortcomings as an entry to care.

RESUMEN

OBJECTIVES: To determine the real-world outcomes associated with using the GetaKit.ca website to distribute COVID self-tests to persons with risk factors, with a focus on facilitating testing for persons who are Black, Indigenous, or of Colour (BIPOC). METHODS: GetaKit was an open cohort observational study to distribute free self-tests, starting with HIV self-testings and then adding the Lucira Check-It® COVID self-test. Participants would register on our website and complete a risk assessment, which would calculate their need for each type of testing. RESULTS: Focusing on the COVID self-tests, from September to December 2021 (with targeted outreach in winter 2022), we distributed 6474 COVID self-tests to 3653 persons through 4161 unique orders, of which 47% came from BIPOC participants. Compared to white participants, BIPOC participants were more likely to have been a contact of COVID but less likely to be vaccinated. As well, 69% of results were reported back via the GetaKit.ca website, with 5.3% of these being positive. The positivity rate for our 3653 participants was 9.6%. CONCLUSIONS: Delivering COVID self-tests via our website provided tests to BIPOC communities and yielded positivity rates that matched local COVID testing centres. This highlights the utility of such systems for delivering testing during future pandemics.

RESUMEN

In Ontario, new HIV diagnoses continue to affect gay, bisexual, and other men who have sex with men (gbMSM) and persons of African, Caribbean, or Black (ACB) ethnicities. Because treatment and suppressed viral loads flow from diagnosis, testing is key. We sought to determine the outcomes of online ordering and mail-out of free at-home HIV self-testing in Ontario, Canada. We implemented the GetaKit study to offer such free HIV self-testing using the INSTI® test and offered it via a website (GetaKit.ca) to eligible persons in Ontario. From April 1, 2021 to January 31, 2022, we distributed kits to 1551 persons; 40% were white and 26% were ACB. We found that ACB participants were less likely to fulfill established criteria for HIV PrEP, such as previous sexually transmitted infections diagnoses and drug use, despite having a similar test positivity rate. We also found that ACB women, who may represent a larger number of new infections than previously thought, did not have a higher rate of first-time testing. Our results suggest that HIV self-testing can enable testing, but that work is required to increase uptake among ACB persons and women. Overall, HIV self-testing thus corresponded with increased testing among persons who were Black, yet lower rates of results reporting. Patient or Public Contributions: Community members from the AIDS Committee of Ottawa, Max Ottawa, and Black Cap, and nurses from Ottawa Public Health were involved in the design, promotion, and implementation of this study.

RESUMEN

Background: HIV self-testing is the latest strategy to improve access to testing, diagnosis and treatment. Such strategies are beneficial due to the improved individual- and population-level health outcomes that emerge from early HIV diagnosis. Aims: While most research shows that HIV self-testing is acceptable and feasible, yielding higher numbers of first-time testers and positivity rates, compared to clinic-based testing, little evidence exists outside low- and middle-income countries about such testing. Methods: We implemented GetaKit.ca, a website through which eligible participants could register for and obtain an INSTI® HIV self-testing to their home, and then report the result back. Results: Those who returned to the website were asked to complete a post-test survey, which had a low response rate (42%), but identified satisfaction scores of 92%. Notably, 5% of testers sought in-person care after ordering the self-test, and only 80% of participants agreed that the INSTI® HIV self-test was easy to use. Conclusions: Participants provided tangible solutions to improve this test, which we feel are easy to incorporate and essential to maintain HIV self-testing efforts.

RESUMEN

Purpose: Use of patient-reported outcomes assessments (PROs) can improve patient-provider communication and focus provider attention on current health issues. This analysis examines the association between suboptimal antiretroviral therapy (ART) adherence and factors obtained through PROs among people with HIV (PWH) at 2 North American outpatient clinics. Patients and Methods: Immediately before a clinic visit, PWH completed self-administered PROs. Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated from logistic regression models to identify sociodemographic and health-related factors (satisfaction with ART, difficulty meeting housing costs, depression, intimate partner violence, risk of malnutrition, smoking status, alcohol use, and substance use) associated with suboptimal adherence (defined as self-reporting <95% or <80% adherence). Multiple imputation was performed to account for missing data in the multivariate analyses. Results: Of 1632 PWH, 1239 (76%) responded to the adherence assessment; of these, 268 (22%) and 106 (9%) reported <95% and <80% adherence, respectively. Of 1580 PWH who responded, 354 (22%) were dissatisfied with their HIV medication. Of responding PWH, 19% reported moderate-to-severe depression, 23% indicated they were at risk of malnutrition, 34% were current smokers, and 62% reported substance use in the past 3 months. Dissatisfaction with ART was significantly associated with <95% and <80% adherence in the unadjusted analysis (unadjusted OR [95% CI], 3.38 [2.51-4.56] and 4.26 [2.82-6.42], respectively) and adjusted analysis (adjusted OR [95% CI], 2.76 [1.91-4.00] and 3.28 [1.95-5.52], respectively); significance remained after multiple imputation. In adjusted analyses, no risk of malnutrition was significantly associated with reduced odds of <95% adherence after multiple imputation (adjusted OR [95% CI], 0.714 [0.511-0.997]); no other factors were associated with <95% or <80% adherence. Conclusion: These results suggest that implementation of PROs evaluating treatment satisfaction may provide value to adherence management in routine HIV care.

RESUMEN

ABSTRACT: HIV self-testing corresponds with more frequent testing, better user satisfaction, and higher positivity rates compared with clinic-based testing. We implemented an open cohort prospective observational study, which provided a website through which persons could do online HIV self-assessments and, if eligible, receive a free HIV self-test. We implemented this project on July 20, 2021 and used the bioLytical INSTI® test. Herein, we describe the number of tests participants reported as invalid, which started at a rate of one fifth of all ordered tests and decreased to 8% after we provided more instructions on completing the test. Our data suggest that a high rate of invalids occur with self-testing in the real-world. Although this has cost implications, we feel this rate is acceptable, considering that 25% of our cohort reported no previous HIV testing. Our take-away message is that HIV self-testing requires additional supports and resources to function as an effective testing intervention.

RESUMEN

The PROgress study assessed the value and feasibility of implementing web-based patient-reported outcomes assessments (PROs) within routine HIV care at two North American outpatient clinics. People with HIV (PWH) completed PROs on a tablet computer in clinic before their routine care visit. Data collection included PROs from 1632 unique PWH, 596 chart reviews, 200 patient questionnaires, and 16 provider/staff questionnaires. During an initial setup phase involving 200 patients, PRO results were not delivered to providers; for all subsequent patients, providers received PRO results before the consultation. Chart review demonstrated that delivery of PRO results to providers improved patient-provider communication and increased the number of complex health and behavioral issues identified, recorded, and acted on, including suicidal ideation (88% with vs 38% without PRO feedback) and anxiety (54% with vs 24% without PRO feedback). In post-visit questionnaires, PWH (82%) and providers (82%) indicated that the PRO added value to the visit.

RESUMEN

BACKGROUND: An optimal adherence to antiretroviral therapy (ART) is fundamental for suppression of HIV viral load and favourable treatment outcomes. Patient-reported outcomes (PROs) are effective tools for improving patient-provider communication and focusing providers' awareness on current health problems. The objectives of this analysis were (1) to determine the feasibility of implementing an electronic screening tool to measure PROs in a Canadian HIV clinic to obtain information on ART adherence and related factors and (2) to determine the factors related to sub-optimal adherence. METHODS: This implementation research with a convenience sample of 600 people living with HIV (PLWH) was conducted in a busy, academic, urban HIV clinic in Toronto, Canada. PLWH were approached to participate in PRO assessments just prior to their in-clinic appointments, including health-related domains such as mental health, housing, nutrition, financial stress and medication adherence, and responses were summarized on a single sheet available for providers to review. Feasibility of implementing PROs was assessed by quantifying response rate, completion rate, time taken and participation rate. Medication adherence was elicited by self-report of the percentage of prescribed HIV medications taken in the last month. Unadjusted and adjusted odds ratios were estimated from logistic regression models to identify factors associated with adherence of <95%. RESULTS: Of the 748 PLWH invited to participate, 692 (participation rate: 92.5%) completed the PRO assessments as standard of care in clinic. Of these, 600 consented to the use of their PRO results for research and were included in this analysis. The average response rate to the ART-related questions was 96.8% and mean completion rate was 95.5%. The median time taken to complete the assessment was 12.0 (IQR = 8.4-17.3) min, adjusted 8.7 (IQR = 7.2-10.8) min. 445 (74.9%) of participants were male, and 153 (26.2%) reported dissatisfaction with ART. 105 (19.7%) of the PLWH reported ART adherence of <95%. Multivariable logistic regression identified the following risk factors for sub-optimal adherence: dissatisfaction with ART (OR = 2.30, 95% CI 1.38-3.83), not having a family doctor or not visiting a family doctor in last year (OR = 1.69, 95% CI 1.02-2.79). CONCLUSION: Collecting self-reported health information from PLWH through PROs in a busy urban clinic was feasible and can provide relevant information to healthcare providers on issues related to adherence. This has a potential to help in individualizing ambulatory care.

RESUMEN

BACKGROUND: The Public Health Agency of Canada estimates that about 87% of persons living with human immunodeficiency virus (HIV) in Canada have been diagnosed, which is well below the Joint United Nations Programme on HIV/AIDS target to have 95% of HIV-positive persons diagnosed. Research has shown that HIV self-testing may help increase such diagnoses, especially among the populations who are most affected by HIV. The objective of the study was to determine the uptake and diagnosis outcomes associated with free HIV self-testing. METHODS: We developed the first online mailout free HIV self-testing program in Canada and implemented it in Ottawa. This project ran through the website, www.GetaKit.ca. We intended to recruit 150-400 participants over a 6-12-month period, estimating that this number would yield between 0-1 positive test results (expected positivity rate of 0.08%). RESULTS: Between July 20, 2020 and April 1, 2021, 1,268 people accessed the GetaKit website and verified their eligibility. In total, 600 persons were eligible and 405 ordered an HIV kit. Of those who ordered a kit, 399 completed a baseline survey. Overall, 71% of these participants were members of HIV priority groups. For test results, 228 persons reported test results, with one being positive, for a positivity rate of 0.24% overall and 0.44% of reported results. These rates exceed that normally observed in Ottawa. CONCLUSION: Self-testing of HIV can be effectively delivered through a website. Such an intervention will also be used by persons with undiagnosed infections and appears to do so at a rate higher than that observed by other means of testing. Self-testing of HIV may therefore help Canada achieve the United Nations 95-95-95 targets.

RESUMEN

Despite the ongoing transmission of sexually transmitted infections (STIs) and HIV, many people became unable to access testing due to COVID-19. To address this, we created a mail-out HIV self-test kit, which could be delivered without restrictions in our region. The uptake and feedback from this project made us realize that comprehensive STI testing was being sought. To ensure testing occurred correctly-that is, it would be targeted at the persons most affected by STIs/HIV-we automated clinical decision-making. We built this model based on a 2-by-2 matrix that plots the risk of STI/HIV transmission and risk of STI/HIV exposure. The intercept of these two measures classifies a person as low, medium, or high risk. After automating this logic, 16 expert clinicians in STI/HIV care tested this system with over 400 test patient cases and refined the algorithm until it yielded the exact outcomes that these clinicians would offer patients based on guidelines. Findings of interest are that the scale of the y-axis is exponential, in that risk factors for exposure do not climb cumulatively but do so according to a quadratic equation. This helps ensure that testing services are targeted at those who are most inequitably burdened by these infections.

RESUMEN

SETTING: In March 2020, COVID-19 shuttered access to many healthcare settings offering HIV testing and there is no licensed HIV self-test in Canada. INTERVENTION: A team of nurses at the University of Ottawa and Ottawa Public Health and staff from the Ontario HIV Treatment Network (OHTN) obtained Health Canada's Special Access approval on April 23, 2020 to distribute bioLytical's INSTI HIV self-test in Ottawa; we received REB approval on May 15, 2020. As of July 20, 2020, eligible participants (≥18 years old, HIV-negative, not on PrEP, not in an HIV vaccine trial, living in Ottawa, no bleeding disorders) could register via www.GetaKit.ca to order kits. OUTCOMES: In the first 6 weeks, 637 persons completed our eligibility screener; 43.3% (n = 276) were eligible. Of eligible participants, 203 completed a baseline survey and 182 ordered a test. These 203 participants were an average of 31 years old, 72.3% were white, 60.4% were cis-male, and 55% self-identified as gay. Seventy-one percent (n = 144) belonged to a priority group for HIV testing. We have results for 70.9% (n = 129/182) of participants who ordered a kit: none were positive, 104 were negative, 22 were invalid, and 2 "preferred not to say"; 1 participant reported an unreadiness to test. IMPLICATIONS: Our results show that HIV self-testing is a pandemic-friendly strategy to help ensure access to sexual health services among persons who are good candidates for HIV testing. It is unsurprising that no one tested positive for HIV thus far, given the 0.08% positivity rate for HIV testing in Ottawa. As such, we advocate for scale-up of HIV self-testing in Canada.


RéSUMé: CONTEXTE: En mars 2020, la COVID-19 a empêché l'accès à de nombreux établissements de santé offrant des tests de dépistage du VIH et il n'existe pas d'autotest du VIH autorisé au Canada. INTERVENTION: Une équipe d'infirmières de l'Université d'Ottawa et de Santé publique Ottawa et le personnel du Réseau ontarien de traitement du VIH (OHTN) ont obtenu l'approbation d'accès spécial de Santé Canada le 23 avril 2020 pour distribuer l'autotest VIH INSTI de bioLytical à Ottawa; nous avons reçu l'approbation du Comité d'éthique de la recherche (CER) le 15 mai 2020. À partir du 20 juillet 2020, les participants admissibles (≥18 ans, séronégatifs, ne prenant pas de PPrE, ne participant pas à un essai de vaccin contre le VIH, vivant à Ottawa, ne souffrant pas de troubles de la coagulation) pouvaient s'inscrire via www.GetaKit.ca pour commander une trousse d'autotest. RéSULTATS: Au cours des six premières semaines, 637 personnes ont rempli notre questionnaire d'admissibilité; 43,3 % (n = 276) étaient admissibles. Parmi les participants admissibles, 203 ont répondu à l'enquête de référence et 182 ont commandé un test. Ces 203 participants avaient en moyenne 31 ans, 72,3 % étaient blancs, 60,4 % étaient hommes-cis et 55 % s'identifiaient comme gays. Soixante et onze pour cent (n = 144) appartenaient à un groupe prioritaire pour le dépistage du VIH. Nous avons les résultats pour 70,9 % (n = 129/182) des participants qui ont commandé une trousse : aucun n'était positif, 104 étaient négatifs; 22 étaient invalides; 2 « préféraient ne pas le dire ¼; et un seul a indiqué qu'il n'était pas prêt à subir le test. CONCLUSION: Nos résultats montrent que l'autodépistage du VIH est une stratégie adaptée à la pandémie pour aider à garantir l'accès aux services de santé sexuelle aux gens qui sont de bons candidats au dépistage du VIH. Il n'est pas surprenant que personne n'ait été testé positif pour le VIH jusqu'à présent, étant donné le taux de positivité de 0,08 % pour le test de dépistage du VIH à Ottawa. C'est ce qui nous incite à préconiser l'intensification du recours à l'autotest du VIH au Canada.
