The study found that the number of non-care workers in care homes had the strongest relationship with the introduction of suspected SARS-CoV-2 cases. Higher staff levels and more severe PPE shortages were associated with higher case counts during the monitoring period. Managing staff interaction with residents and working practices could help reduce the ingress and spread of COVID-19-like illnesses within these care homes.
Background Residential care homes for the elderly are important settings for transmission of the SARS-CoV-2 virus that causes COVID-19 disease. Methods We undertook secondary analysis of 248 care homes in Norfolk, UK. The dataset counted nurses, care workers and non-care workers, their status (available, absent due to leave or sickness and extra staff needed to address the coronavirus pandemic) and residents (if any) with suspected COVID-19 in the period 6 April to 6 May 2020. Concurrent descriptions of access by the home to personal protection equipment (PPE: gloves, masks, eye protection, aprons and sanitizer) were in the data. PPE access was categorized as (most to least) green, amber or red. We undertook two-stage modelling, first for suspected COVID-19 cases amongst residents and second relating any increases in case counts after introduction to staffing or PPE levels. Results Counts of non-care workers had strongest relationships (P < 0.05) to introduction of suspected SARS-CoV-2 to the homes. Higher staff levels and more severe PPE shortages were linked to higher case counts (P < 0.05) during the monitoring period. Conclusion Managing aspects of staff interaction with residents and some working practices might reduce ingression to and spread of COVID-19-like illness within care homes.
