Drivers of COVID-19 Outcomes in Long-Term Care Facilities Using Multi-Level Analysis: A Systematic Review

This study aimed to identify the individual, organizational, and environmental factors which contributed to COVID-19-related outcomes in long-term care facilities (LTCFs). A systematic review was conducted to summarize and synthesize empirical studies using a multi-level analysis approach to address the identified influential factors. Five databases were searched on 23 May 2023. To be included in the review, studies had to be published in peer-reviewed journals or as grey literature containing relevant statistical data. The Joanna Briggs Institute critical appraisal tool was employed to assess the methodological quality of each article included in this study. Of 2137 citations identified after exclusions, 99 records met the inclusion criteria. The predominant individual, organizational, and environmental factors that were most frequently found associated with the COVID-19 outbreak comprised older age, higher dependency level; lower staffing levels and lower star and subset domain ratings for the facility; and occupancy metrics and co-occurrences of outbreaks in counties and communities where the LTCFs were located, respectively. The primary individual, organizational, and environmental factors frequently linked to COVID-19-related deaths comprised age, and male sex; higher percentages of racial and ethnic minorities in LTCFs, as well as ownership types (including private, for-profit, and chain membership); and higher occupancy metrics and LTCF's size and bed capacity, respectively. Unfolding the risk factors collectively may mitigate the risk of outbreaks and pandemic-related mortality in LTCFs during future endemic and pandemics through developing and improving interventions that address those significant factors.

Moral failure, moral prudence, and character challenges in residential care during the Covid-19 pandemic

In many high-income countries, an initial response to the severe impact of Covid-19 on residential care was to shield residents from outside contacts. As the pandemic progressed, these measures have been increasingly questioned, given their detrimental impact on residents' health and well-being and their dubious effectiveness. Many authorities have been hesitant in adapting visiting policies, often leaving nursing homes to act on their own safety and liability considerations. Against this backdrop, this article discusses the appropriateness of viewing the continuation of the practice of shielding as a moral failure. This is affirmed and specified in four dimensions: preventability of foreseeable harm, moral agency, moral character, and moral practice (in MacIntyre's sense). Moral character is discussed in the context of prudent versus proportionate choices. As to moral practice, it will be shown that the continued practice of shielding no longer met the requirements of an (inherently moral) practice, as external goods such as security thinking and structural deficiencies prevented the pursuit of internal goods focusing on residents' interests and welfare, which in many places has led to a loss of trust in these facilities. This specification of moral failure also allows a novel perspective on moral distress, which can be understood as the expression of the psychological impact of moral failure on moral agents. Conclusions are formulated about how pandemic events can be understood as character challenges for healthcare professionals within residential care, aimed at preserving the internal goods of residential care even under difficult circumstances, which is understood as a manifestation of moral resilience. Finally, the importance of moral and civic education of healthcare students is emphasized to facilitate students' early identification as trusted members of a profession and a caring society, in order to reduce experiences of moral failure or improve the way to deal with it effectively.

SARS-CoV-2 susceptibility and COVID-19 illness course and outcome in people with pre-existing neurodegenerative disorders: systematic review with frequentist and Bayesian meta-analyses

BACKGROUND

People with neurodegenerative disease and mild cognitive impairment (MCI) may have an elevated risk of acquiring severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and may be disproportionally affected by coronavirus disease 2019 (COVID-19) once infected.

AIMS

To review all eligible studies and quantify the strength of associations between various pre-existing neurodegenerative disorders and both SARS-CoV-2 susceptibility and COVID-19 illness course and outcome.

METHOD

Pre-registered systematic review with frequentist and Bayesian meta-analyses. Systematic searches were executed in PubMed, Web of Science and preprint servers. The final search date was 9 January 2023. Odds ratios (ORs) were used as measures of effect.

RESULTS

In total, 136 primary studies (total sample size n = 97 643 494), reporting on 268 effect-size estimates, met the inclusion criteria. The odds for a positive SARS-CoV-2 test result were increased for people with pre-existing dementia (OR = 1.83, 95% CI 1.16-2.87), Alzheimer's disease (OR = 2.86, 95% CI 1.44-5.66) and Parkinson's disease (OR = 1.65, 95% CI 1.34-2.04). People with pre-existing dementia were more likely to experience a relatively severe COVID-19 course, once infected (OR = 1.43, 95% CI 1.00-2.03). People with pre-existing dementia or Alzheimer's disease were at increased risk for COVID-19-related hospital admission (pooled OR range: 1.60-3.72). Intensive care unit admission rates were relatively low for people with dementia (OR = 0.54, 95% CI 0.40-0.74). All neurodegenerative disorders, including MCI, were at higher risk for COVID-19-related mortality (pooled OR range: 1.56-2.27).

CONCLUSIONS

Our findings confirm that, in general, people with neurodegenerative disease and MCI are at a disproportionally high risk of contracting COVID-19 and have a poor outcome once infected.
