Impact of SARS-CoV2 infection on mortality and hospitalization in nursing home residents during the "Omicron era".

BACKGROUND: Widespread vaccination and emergence of less aggressive SARS-CoV2 variants may have blunted the unfavourable outcomes of COVID-19 in nursing home (NH) residents. We analysed the course of COVID-19 epidemic in NHs of Florence, Italy, during the "Omicron era" and investigated the independent effect of SARS-CoV2 infection on death and hospitalization risk. METHODS: Weekly SARS-CoV2 infection rates between November 2021 and March 2022 were calculated. Detailed clinical data were collected in a sample of NHs. RESULTS: Among 2044 residents, 667 SARS-CoV2 cases were confirmed. SARS-CoV2 incidence sharply increased during the Omicron era. Mortality rates did not differ between SARS-CoV2-positive (6.9%) and SARS-CoV2-negative residents (7.3%, p = 0.71). Chronic obstructive pulmonary disease and poor functional status, but not SARS-CoV2 infection independently predicted death and hospitalization. CONCLUSIONS: Despite that SARS-CoV2 incidence increased during the Omicron era, SARS-CoV2 infection was not a significant predictor of hospitalization and death in the NH setting.

Predictors of 1-year outcome in very old patients managed in a Heart Failure Unit after an acute decompensation.

PURPOSE: Consensus exits about the clinical benefits of an early referral to multidisciplinary Heart Failure Unit-HFU for old frail patients with HF. Nevertheless, few data are present regarding the prognosis and the predictors of outcome in oldest-old patients managed in this clinical setting. The aim of present study is to identify predictors of 1-year all-cause mortality in very old patients enrolled in our multidisciplinary HFU after an episode of acute decompensated HF. METHODS: This study is a retro-prospective, single-center cohort analysis of patients managed in our multidisciplinary HFU. Inclusion criterion was diagnosis of HF according to ESC guidelines and age ≥ 85 years, while no exclusion criteria were pre-defined. Baseline clinical and comprehensive geriatric evaluations were recorded during the first visit and follow-up visits were repeated according to our standardized timetable protocol. Primary end-point was 1-year all-cause mortality. RESULTS: We enrolled 75 patients aged 89.2 ± 2.8 years; 39 (52.0%) were females. During 1-year follow-up, seventeen patients (22.7%) died. Residual congestion with higher level (> 4) of EVEREST score (HR 1.24: 95% CI 1.04-1.47) and living alone (HR 3.34: 95% CI 1.16-9.64) resulted the two independent predictors of 1-year all-cause mortality at the multivariate Cox regression model. Finally, patients living alone and with an EVEREST score > 4 experienced a worse prognosis as clearly described by a steeper descendent Kaplan-Meier curve. CONCLUSION: In a very old population of patients after an acute decompensated HF, residual congestion and social isolation as living alone identify those with high risk of 1-year death.
