How did COVID-19 lockdown impact the health of older adults in nursing homes? A scoping review

The impact of the COVID-19 pandemic on older adults in nursing homes is significant, with high death rates, disrupted care, isolation measures, and inadequate treatment. Social isolation has increased risks of cognitive disorders, anxiety, and depression. While many studies have examined the pandemic's effects on nursing home staff and residents' families, less is known about the health consequences for the residents themselves. This review aims to synthesize literature on the COVID-19 lockdown's impact on the functional, cognitive, and psycho-emotional states of older adults in nursing homes. A scoping review was conducted following the Joanna Briggs Institute guidelines and the PRISMA extension for Scoping Reviews (PRISMA-ScR). Four databases were searched: CINAHL, PubMed, Web of Science, and PsycINFO. The eligibility criteria included studies on older adults in nursing homes during the COVID-19 pandemic, with data that could be disaggregated for this population and results on the lockdown's impact on physical, cognitive, and psycho-emotional levels. Seventeen articles met the criteria for data extraction The synthesis was categorized into four main areas: functional, cognitive and psycho-emotional status, and isolation measures. Key findings included decreased functional abilities, lower cognitive test scores during the pandemic's first waves, development of psychological symptoms, and increased negative feelings among residents. Highlighting the consequences of confinement for nursing home residents is essential for updating evidence, developing effective strategies, and establishing protocols to mitigate the impact and prevent health issues in future pandemics.
