Excess mortality among older adults institutionalized in long-term care facilities during the COVID-19 pandemic: a population-based analysis in Catalonia.

Objectives: To assess excess mortality among older adults institutionalized in nursing homes within the successive waves of the COVID-19 pandemic in Catalonia (north-east Spain). Design: Observational, retrospective analysis of population-based central healthcare registries. Setting and participants: Individuals aged >65 years admitted in any nursing home in Catalonia between January 1, 2015, and April 1, 2022. Methods: Deaths reported during the pre-pandemic period (2015-2019) were used to build a reference model for mortality trends (a Poisson model, due to the event counting nature of the variable "mortality"), adjusted by age, sex, and clinical complexity, defined according to the adjusted morbidity groups. Excess mortality was estimated by comparing the observed and model-based expected mortality during the pandemic period (2020-2022). Besides the crude excess mortality, we estimated the standardized mortality rate (SMR) as the ratio of weekly deaths' number observed to the expected deaths' number over the same period. Results: The analysis included 175,497 older adults institutionalized (mean 262 days, SD 132), yielding a total of 394,134 person-years: 288,948 person-years within the reference period (2015-2019) and 105,186 within the COVID-19 period (2020-2022). Excess number of deaths in this population was 5,403 in the first wave and 1,313, 111, -182, 498, and 329 in the successive waves. The first wave on March 2020 showed the highest SMR (2.50; 95% CI 2.45-2.56). The corresponding SMR for the 2nd to 6th waves were 1.31 (1.27-1.34), 1.03 (1.00-1.07), 0.93 (0.89-0.97), 1.13 (1.10-1.17), and 1.07 (1.04-1.09). The number of excess deaths following the first wave ranged from 1,313 (2nd wave) to -182 (4th wave). Excess mortality showed similar trends for men and women. Older adults and those with higher comorbidity burden account for higher number of deaths, albeit lower SMRs. Conclusion: Excess mortality analysis suggest a higher death toll of the COVID-19 crisis in nursing homes than in other settings. Although crude mortality rates were far higher among older adults and those at higher health risk, younger individuals showed persistently higher SMR, indicating an important death toll of the COVID-19 in these groups of people.

Risk Factors for Mortality in Nursing Home Residents: An Observational Study.

Purpose: Identifying mortality risk factors in people living in nursing homes could help healthcare professionals to individualize or develop specific plans for predicting future care demands and plan end-of-life care in this population. This study aims to identify mortality risk factors in elderly nursing home (NH) residents, based on variables adapted to this environment, routinely collected and easily accessible to their healthcare professionals. Methods: A prospective, longitudinal, observational study of NH residents aged 65 years and older was carried out collecting sociodemographic, functional and cognitive status, nutritional variables, comorbidities, and other health variables. These variables were analyzed as mortality risk factors by Cox proportional hazard models. Results: A total of 531 residents (75.3% female; average age 86.7 years (SD: 6.6)) were included: 25.6% had total dependence, 53.4% had moderate to severe cognitive impairment, 84.5% were malnourished or at risk of malnutrition, and 79.9% were polymedicated. Risk of mortality (hazard ratio, HR) increased in totally dependent residents (HR = 1.52; p = 0.02) and in those with moderate or severe cognitive impairment ((HR = 1.59; p = 0.031) and (HR = 1.93; p = 0.002), respectively). Male gender (HR = 1.88; p < 0.001), age ≥80 years (HR = 1.73; p = 0.034), hypertension (HR = 1.53; p = 0.012), atrial fibrillation/arrhythmia (HR = 1.43; p = 0.048), and previous record of pneumonia (HR = 1.65; p = 0.029) were also found to be mortality drivers. Conclusion: Age and male gender (due to the higher prevalence of associated comorbidity in these two variables), certain comorbidities (hypertension, atrial fibrillation/arrhythmia, and pneumonia), higher functional and cognitive impairment, and frequency of medical emergency service care increased the risk of mortality in our study. Given their importance and their easy identification by healthcare professionals in nursing homes, these clinical variables should be used for planning care in institutionalized older adults.

Complejidad y prevalencia de síndromes geriátricos de los pacientes atendidos en unidades sociosanitarias en Catalunya. Estudio multicéntrico del proyecto XARESS / Complexity and prevalence of geriatric syndromes in patients treated in intermediate care units in Catalonia: A multicentre study of XARESS project

Fundamentos: El objetivo fue describir la complejidad y prevalencia de síndromes geriátricos (SG) en unidades sociosanitarias de Catalunya. Métodos: Se estudiaron retrospectivamente 6.471 estancias realizadas durante el año 2014 en los centros participantes del XARESS. Los datos se obtuvieron a partir de la explotación del registro Conjunto Mínimo Básico de Datos de los Recursos Sociosanitarios (CMBD-RSS). Se analizaron de forma descriptiva las prevalencias y las asociaciones entre SG y categoría RUG al ingreso, estancia media y destino al alta, estratificando por tipo de unidad (convalecencia o larga estancia). Resultados: Los participantes presentaron una mediana de 3 SG al ingreso en larga estancia y 2 SG en convalecencia. El número de SG varió con la categoría RUG, aunque en todas ellas se identificaron pacientes sin complejidad (0 SG) y con extrema complejidad (9 SG). La presencia de SG se asoció a estancias medias más largas y mayor dependencia, aunque con gran variabilidad entre SG. No se encontró relación entre los SG y el destino al alta sociosanitaria. Conclusiones: La población atendida en centros sociosanitarios presenta una elevada complejidad y una alta prevalencia de SG al ingreso. La explotación del CMBD-RSS permite caracterizar la complejidad de las personas ingresadas en los centros de convalecencia y larga estancia de la red sociosanitaria catalana

Background: Descriptive study is presented on the complexity and prevalence of geriatric syndromes (GS) in Intermediate Care Units in Catalonia. Methods: A retrospective study was conducted on 6471 stays completed during the year 2014 in the participating centres of the XARESS network. Data was obtained by extracting the information routinely collected on the CMBD-RSS registry (Minimum Basic Dataset for the Intermediate Care Resources). The prevalence and associations between geriatric síndromes (resource group) RG category, length of stay, and destination at discharge is described. Results were stratified by type of unit (convalescence or long stay). Results: Participants presented a median of 3 GS at admission in long stay units, and 2 GS at admission in convalescence units. The number of GS varied with RG category, although in all RG categories, there were patients without complexity (no SG), and patients with extreme complexity (up to 9 GS). Patients with geriatric syndromes had a longer mean length of stay and greater dependence than patients without syndromes, although with great variability across GS. However, the presence of geriatric syndromes had no impact on the destination at discharge. Conclusions: The population cared for in intermediate care units have high complexity and a high prevalence of geriatric syndromes at admission. The CMBD-RSS registry allows the characterisation of complexity of the population admitted to the Catalan convalescence and long term intermediate care units
