ABSTRACT
Background: The greatest impact of the COVID-19 pandemic in Canada has been on long-term care facilities which have accounted for a large majority of the mortality seen in this country. We developed a clinical response team to perform mass assessment and provide support to long-term care facilities in Eastern Ontario with large outbreaks in the hope of reducing the impact of the outbreaks. Methods: This is a retrospective cohort study of all residents of LTC facilities supported by our multidisciplinary clinical response team. We collected data about the timing of the outbreak and our deployment, as well as the total number of COVID-19 cases and deaths, and measured the correlation between the timing of our deployment and the observed mortality rate. Results: Our clinical team was deployed to 14 long-term care facilities, representing 719 cases and 243 deaths (mean ± standard error of mortality 34% ± 4%). Our team was deployed a mean ± standard error of 16 ± 2 days after the declaration of an outbreak. There was a significant correlation between an earlier deployment of our clinical team and a lower mortality rate for that outbreak (Pearson's r = 0.70, p < .01). Interpretation: This retrospective, uncontrolled study of a non-standardized intervention has many potential limitations. However, the data suggest that timely deployment of our clinical response team may improve outcomes in the event of a large outbreak. This clinical team may be useful in future pandemics.
