COVID-19 infection and 2-year mortality in nursing home residents who survived the first wave of the pandemic.

BACKGROUND: During the first COVID-19 pandemic wave (1st CoPW), nursing homes (NHs) experienced a high rate of COVID-19 infection and death. Residents who survived the COVID-19 infection may have become frailer. This study aimed to determine the predictive value of having a COVID-19 infection during the 1st CoPW for 2-year mortality in NH residents. METHODS: This was a retrospective study conducted in three NHs. Residents who had survived the 1st CoPW (March to May 2020) were included. The diagnosis of COVID-19 was based on the results of a positive reverse transcriptase-polymerase chain reaction test. The collected data also included age, sex, length of residence in the NH, disability status, legal guardianship status, nutritional status, need for texture-modified food, hospitalization or Emergency Department visits during lockdown and SARS-COV2 vaccination status during the follow-up. Non-adjusted and adjusted Cox models were used to analyse factors associated with 2-year post-1st CoPW mortality. RESULTS: Among the 315 CoPW1 survivors (72% female, mean age 88 years, 48% with severe disability), 35% presented with COVID-19. Having a history of COVID-19 was not associated with 2-year mortality: hazard ratio (HR) [95% confidence interval] = 0.96 [0.81-1.13], p = 0.62. The factors independently associated with 2-year mortality were older age (for each additional year, HR = 1.05 [1.03-1.08], p < 0.01), severe disability vs. moderate or no disability (HR = 1.35 [1.12-1.63], p < 0.01) and severe malnutrition vs. no malnutrition (HR = 1.29 [1.04-1.60], p = 0.02). Considering that vaccination campaign started during the follow-up, mortality was associated with severe malnutrition before and severe disability after the start of the campaign. Vaccination was independently associated with better survival (HR 0.71 [0.55-0.93], p = 0.02). CONCLUSIONS: Having survived a COVID-19 infection during the 1st CoPW did not affect subsequent 2-year survival in older adults living in NHs. Severe malnutrition and disability remained strong predictor of mortality in this population, whereas vaccination was associated to better survival.

COVID-19 as an Independent Risk Factor for Weight Loss in Older Adults Living in Nursing Homes.

INTRODUCTION: In nursing homes, where residents are at elevated risk for malnutrition, the specific additive effect of the coronavirus disease 2019 (COVID-19) on weight loss has not yet been adequately evaluated. This study aimed to determine the factors independently associated with weight loss in nursing home residents who survived the first wave of the COVID-19 pandemic, whether they have contracted COVID-19 or not. METHODS: This research was a retrospective study conducted in three nursing homes. Residents who survived the first French COVID-19 lockdown (March to May 2020) were included, provided their weight records were available. Baseline data included the body mass index (BMI), capacity to self-feed, need for texture-modified food, disability, and legal guardianship status. The diagnosis of COVID-19 was based on the results of a positive reverse transcriptase-polymerase chain reaction test. Univariate and multivariate logistic regression analyses were used to investigate associations between resident characteristics, COVID-19 status, and at least 5% weight loss. RESULTS: Of the 316 included residents (72% female, mean age of 88 years, 48% severely disabled, and 38% under legal guardianship), 111 (35%) contracted COVID-19 and 102 (32%) lost at least 5% of their body weight. No difference was observed between the baseline characteristics of residents subsequently affected or unaffected by COVID-19. In the univariate analysis, old age, severe disability, texture-modified food, the need for close mealtime supervision, and COVID-19 were significantly associated with at least 5% weight loss. In the multivariate logistic regression analysis, COVID-19 (p = 0.02) and the need for close mealtime supervision (p = 0.02) were associated with weight loss in a model that also included age, BMI, texture-modified food, disability, and nursing home. CONCLUSION: For nursing home residents, COVID-19 was an independent risk factor for weight loss. Weight loss was most common in residents needing close mealtime supervision, suggesting that organizational issues may have affected the quality of the nutritional care provided during the lockdown.
