The significant impact of COVID-19 worldwide has made it necessary to develop tools to identify patients at high risk of severe disease and death. This work aims to validate the RIM Score-COVID in the SEMI-COVID-19 Registry. The RIM Score-COVID is a simple nomogram with high predictive capacity for in-hospital death due to COVID-19 designed using clinical and analytical parameters of patients diagnosed in the first wave of the pandemic. The nomogram uses five variables measured on arrival to the emergency department (ED): age, sex, oxygen saturation, C-reactive protein level, and neutrophil-to-platelet ratio. Validation was performed in the Spanish SEMI-COVID-19 Registry, which included consecutive patients hospitalized with confirmed COVID-19 in Spain. The cohort was divided into three time periods: T1 from February 1 to June 10, 2020 (first wave), T2 from June 11 to December 31, 2020 (second wave, pre-vaccination period), and T3 from January 1 to December 5, 2021 (vaccination period). The model’s accuracy in predicting in-hospital COVID-19 mortality was assessed using the area under the receiver operating characteristics curve (AUROC). Clinical and laboratory data from 22,566 patients were analyzed: 15,976 (70.7%) from T1, 4,233 (18.7%) from T2, and 2,357 from T3 (10.4%). AUROC of the RIM Score-COVID in the entire SEMI-COVID-19 Registry was 0.823 (95%CI 0.819–0.827) and was 0.834 (95%CI 0.830–0.839) in T1, 0.792 (95%CI 0.781–0.803) in T2, and 0.799 (95%CI 0.785–0.813) in T3. The RIM Score-COVID is a simple, easy-to-use method for predicting in-hospital COVID-19 mortality that uses parameters measured in most EDs. This tool showed good predictive ability in successive disease waves. Supplementary Information The online version contains supplementary material available at 10.1007/s11739-023-03200-3.

BackgroundThe aging population is an increasing concern in Western hospital systems. The aim of this study was to describe the main characteristics and hospitalization patterns in very elderly inpatients (≥ 85 years) in Spain from 2000 to 2015.MethodsRetrospective observational study analyzing data from the minimum basic data set, an administrative registry recording each hospital discharge in Spain since 1997. We collected administrative, economic and clinical data for all discharges between 2000 and 2015 in patients aged 85 years and older, reporting results in three age groups and four time periods to assess differences and compare trends.ResultsThere were 4,387,326 admissions in very elderly patients in Spain from 2000 to 2015, representing 5.32% of total admissions in 2000–2003 and 10.42% in 2012–2015. The pace of growth was faster in older age groups, with an annual percentage increase of 6% in patients aged 85–89 years, 7.79% in those aged 90–94 years, and 8.06% in those aged 95 and older. The proportion of men also rose (37.3–39.7%, p < 0.001), and they had a higher incidence of hospitalization than women (385 discharges/1000 men versus 280 discharges/1000 women in 2012–2015).There were 4,387,326 admissions in very elderly patients in Spain from 2000 to 2015, representing 5.32% of total admissions in 2000–2003 and 10.42% in 2012–2015. The pace of growth was faster in older age groups, with an annual percentage increase of 6% in patients aged 85–89 years, 7.79% in those aged 90–94 years, and 8.06% in those aged 95 and older. The proportion of men also rose (37.3% to 39.7%, p<0.001), and they had a higher incidence of hospitalization than women (385 discharges/1000 men versus 280 discharges/1000 women in 2012–2015).Mortality decreased from 14.64% in 2000–2003 to 13.83% in 2012–2015 (p<0.001), and mean length of stay from 9.98 days in 2000–2003 to 8.34 days in 2012–2015. Costs per hospital stay increased from 2000 to 2011, from EUR 4611 in 2000–2003 to EUR 5212 in 2008–2011, before dropping to EUR 4824 in 2012–2015. The 10 most frequent discharge diagnoses in the period 2000-2003 were: femoral neck fracture (8.07%), heart failure (7.84%), neoplasms (7.65%), ischemic encephalopathy (6.97%), pneumonia (6.36%), chronic obstructive pulmonary disease (4.23%), ischemic cardiomyopathy (4.2%), other respiratory diseases (3.87%), other alterations of urethra and the urinary tract (3.08%), and cholelithiasis (3.07%). ConclusionsThe very elderly population is growing in Spanish hospitals, and within this group, patients are getting older and more frequently male. The mean length of stay, cost of stay, and mortality are decreasing. Decompensation of chronic diseases, neoplasms and infections are the most common causes of admission.
