Abstract
<h4>Objectives</h4>To estimate the incidence of gastroenteritis in individuals in care homes.<h4>Design</h4>Prospective cohort study.<h4>Setting</h4>Five participating care homes in North West England, UK.<h4>Participants</h4>Residents and staff present at the five study care homes between 15 August 2017 and 30 May 2019 (n=268).<h4>Outcome measures</h4>We calculated incidence rates for all gastroenteritis cases per 1000 person-years at risk and per 1000 bed-days at risk. We also calculated the incidence rate of gastroenteritis outbreaks per 100 care homes per year.<h4>Results</h4>In total 45 cases were reported during the surveillance period, equating to 133.7 cases per 1000 person-years at risk. In residents the incidence rate was 0.62 cases per 1000 bed-days. We observed seven outbreaks in all care homes included in surveillance, a rate of 76.4 outbreaks per 100 care homes per year. 15 stool samples were tested; three were positive for norovirus, no other pathogens were detected.<h4>Conclusions</h4>We found that surveillance of infectious gastroenteritis disease in care homes based on outbreaks, the current general approach, detected a majority of cases of gastroenteritis. However, if policymakers are to estimate the burden of infectious gastroenteritis in this setting using only routine outbreak surveillance data and not accounting for non-outbreak cases, this study implies that the total burden will be underestimated.
