Leveraging corona virus disease 2019 vaccination to promote hepatitis C screening.

Health care initiatives, such as hepatitis C virus (HCV) screening, have been greatly overshadowed by the corona virus disease 2019 (COVID-19) pandemic. However, COVID-19 vaccination programs also provide an opportunity to engage with a high volume of people in a health care setting. We collaborated with a large COVID vaccination center to offer HCV point-of-care testing followed by dried blood spot collection for HCV RNA. Additionally, this opportunity was used to evaluate the practical significance of a 5-minute version of the OraQuick HCV antibody test in lieu of the standard 20-minute test. We tested 2317 individuals; 31 were HCV antibody positive and six were RNA positive of which four were treated and reached sustained virological response. Over a third of those surveyed said they would not have participated had the test required 20 minutes. Conclusion: Colocalizing HCV testing and linkage to care at a COVID vaccination clinic was found to be highly feasible; furthermore, a shortened antibody test greatly improves the acceptance of testing.

Association between virtual primary care and emergency department use during the first year of the COVID-19 pandemic in Ontario, Canada.

BACKGROUND: Uptake of virtual care increased substantially during the first year of the COVID-19 pandemic. The aim of this study was to evaluate whether a shift from in-person to virtual visits by primary care physicians was associated with increased use of emergency departments among their enrolled patients. METHODS: We conducted an observational study of monthly virtual visits and emergency department visits from Apr. 1, 2020, to Mar. 31, 2021, using administrative data from Ontario, Canada. We used multivariable regression analysis to estimate the association between the proportion of a physician's visits that were delivered virtually and the number of emergency department visits among their enrolled patients. RESULTS: The proportion of virtual visits was higher among female, younger and urban physicians, and the number of emergency department visits was lower among patients of female and urban physicians. In an unadjusted analysis, a 1% increase in a physician's proportion of virtual visits was found to be associated with 11.0 (95% confidence interval [CI] 10.1-11.8) fewer emergency department visits per 1000 rostered patients. After controlling for covariates, we observed no statistically significant change in emergency department visits per 1% increase in the proportion of virtual visits (0.2, 95% CI -0.5 to 0.9). INTERPRETATION: We did not find evidence that patients substituted emergency department visits in the context of decreased availability of in-person care with their family physician during the first year of the COVID-19 pandemic. Future research should focus on the long-term impact of virtual care on access and quality of patient care.

The impact of the first, second and third waves of covid-19 on hepatitis B and C testing in Ontario, Canada.

The COVID-19 pandemic interrupted routine healthcare services. Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are often asymptomatic, and therefore, screening and on/post-treatment monitoring are required. Our aim was to determine the effect of the first, second and third waves of the pandemic on HBV and HCV testing in Ontario, Canada. We extracted data from Public Health Ontario for HBV and HCV specimens from 1 January 2019 to 31 May 2021. Testing volumes were evaluated and stratified by age, sex and region. Changes in testing volumes were analysed by per cent and absolute change. Testing volumes decreased in April 2020 with the first wave of the pandemic and recovered to 72%-75% of prepandemic volumes by the end of the first wave. HBsAg testing decreased by 33%, 18% and 15%, and HBV DNA testing decreased by 37%, 27% and 20%, in each consecutive wave. Anti-HCV testing decreased by 35%, 21% and 19%, and HCV RNA testing decreased by 44%, 30% and 36% in each consecutive wave. These trends were consistent by age, region and sex. Prenatal HBV testing volumes were stable. In conclusion, significant decreases in HBV and HCV testing occurred during the first three waves of the pandemic and have not recovered. In addition to direct consequences on viral hepatitis elimination efforts, these data provide insight into the impacts of the pandemic on chronic disease screening and management. Strategies to make up for missed testing will be critical to avoid additional consequences of COVID-19 long after the pandemic has resolved.
