Investigating the association between COVID-19 vaccination and care home outbreak frequency and duration

Analysis of the impact of COVID-19 on Scotland's care-homes from March 2020 to October 2021: national linked data cohort analysis

BACKGROUND

The impact of the COVID-19 pandemic on long-term care residents remains of wide interest, but most analyses focus on the initial wave of infections.

OBJECTIVE

To examine change over time in: (i) The size, duration, classification and pattern of care-home outbreaks of COVID-19 and associated mortality and (ii) characteristics associated with an outbreak.

DESIGN

Retrospective observational cohort study using routinely-collected data.

SETTING

All adult care-homes in Scotland (1,092 homes, 41,299 places).

METHODS

Analysis was undertaken at care-home level, over three periods. Period (P)1 01/03/2020-31/08/2020; P2 01/09/2020-31/05/2021 and P3 01/06/2021-31/10/2021. Outcomes were the presence and characteristics of outbreaks and mortality within the care-home. Cluster analysis was used to compare the pattern of outbreaks. Logistic regression examined care-home characteristics associated with outbreaks.

RESULTS

In total 296 (27.1%) care-homes had one outbreak, 220 (20.1%) had two, 91 (8.3%) had three, and 68 (6.2%) had four or more. There were 1,313 outbreaks involving residents: 431 outbreaks in P1, 559 in P2 and 323 in P3. The COVID-19 mortality rate per 1,000 beds fell from 45.8 in P1, to 29.3 in P2, and 3.5 in P3. Larger care-homes were much more likely to have an outbreak, but associations between size and outbreaks were weaker in later periods.

CONCLUSIONS

COVID-19 mitigation measures appear to have been beneficial, although the impact on residents remained severe until early 2021. Care-home residents, staff, relatives and providers are critical groups for consideration and involvement in future pandemic planning.

A qualitative exploration of the clinical presentation, trajectory, management and recovery of COVID-19 in older people: Learning from frontline staff experiences

COVID-19 had a devastating impact on older people living in care homes. This study explored the clinical trajectory and management of COVID-19, as well as recovery of older people following infection during the early stages of the pandemic (May to August 2020). A two-phase exploratory qualitative study was used. Frontline staff with experience of caring for older people with COVID-19 were recruited to Phase 1, and senior care home operational and quality managers were recruited to Phase 2. During Phase 1 remote semi-structured interviews (n = 35) were carried out with staff working in care homes, hospital and community settings in England. During Phase 2, a remote consultation event was carried out with senior care home operational and quality managers (n = 11) to share Phase 1 findings and check resonance, relevance and gaps. Data were analysed using Framework Analysis. Older people with COVID-19 presented with wide ranging symptoms, and an unpredictable illness trajectory. The wide range of COVID-19 symptoms required timely testing and supportive interventions. Staff used different interventions to manage symptoms and reported uncertainties of how individuals would respond. In care home settings, health and social care staff needed to work together when administering interventions such as subcutaneous fluids or oxygen therapy. Alongside symptom management, supportive care focused on nutrition and hydration, social interaction, and maintaining physical activity to meet both physical and emotional needs. The effects of prolonged periods of social isolation and inactivity on the health and well-being of older people means rehabilitation is essential to enhance physical and emotional recovery, and to minimise impacts on cognition and function. The pandemic highlighted important areas for care of this population.
