Objective: To analyse the rate of occurrence and the clinical variables associated with readmission of patients who had previously been discharged after admission for COVID-19. Setting: University hospital in Madrid (Spain). Participants: Sixty-one patients (74% male) who presented COVID-19 were readmitted during the 3 weeks after discharge from hospital. Interventions: Nested case–control study paired (1:1 ratio) by age, sex and period of admission. Outcome Measures: Rate of readmission rate of patients discharged after suffering COVID-19 and identification of the clinical variables associated with it. Results: Out of 1368 patients who were discharged during the study period, 61 patients (4.4%) were readmitted. Immunocompromised patients (N=10.2%) were at increased risk for readmission (p=0.04). There was also a trend towards a higher probability of readmission in hypertensive patients (p=0.07). Cases had had a shorter hospital stay and a higher prevalence of fever during the 48 hours prior to discharge. There were no significant differences in oxygen levels measured at admission and discharge by pulse oximetry intra-subject or between the groups. Neutrophil-to-lymphocyte ratio at hospital admission tended to be higher in cases than in controls (p=0.06). Neither glucocorticoids nor anticoagulants prescribed at hospital discharge were associated with a lower readmission rate. Patients who were readmitted due to a thrombotic event (8 patients, 13.1%) presented a higher level of D-dimer at discharge of initial admission. Conclusion: The rate of readmission after discharge from hospital for COVID-19 was low. Immunocompromised patients and those presenting with fever during the 48 hours prior to discharge were at greater risk of readmission to hospital.

To determine the proportion of patients with COVID-19 who were readmitted to the hospital and the most common causes and the factors associated with readmission. Multicenter nationwide cohort study in Spain. Patients included in the study were admitted to 147 hospitals from March 1 to April 30, 2020. Readmission was defined as a new hospital admission during the 30 days after discharge. Emergency department visits after discharge were not considered readmission. During the study period 8392 patients were admitted to hospitals participating in the SEMI-COVID-19 network. 298 patients (4.2%) out of 7137 patients were readmitted after being discharged. 1541 (17.7%) died during the index admission and 35 died during hospital readmission (11.7%, p = 0.007). The median time from discharge to readmission was 7 days (IQR 3–15 days). The most frequent causes of hospital readmission were worsening of previous pneumonia (54%), bacterial infection (13%), venous thromboembolism (5%), and heart failure (5%). Age [odds ratio (OR): 1.02; 95% confident interval (95% CI): 1.01–1.03], age-adjusted Charlson comorbidity index score (OR: 1.13; 95% CI: 1.06–1.21), chronic obstructive pulmonary disease (OR: 1.84; 95% CI: 1.26–2.69), asthma (OR: 1.52; 95% CI: 1.04–2.22), hemoglobin level at admission (OR: 0.92; 95% CI: 0.86–0.99), ground-glass opacification at admission (OR: 0.86; 95% CI:0.76–0.98) and glucocorticoid treatment (OR: 1.29; 95% CI: 1.00–1.66) were independently associated with hospital readmission. The rate of readmission after hospital discharge for COVID-19 was low. Advanced age and comorbidity were associated with increased risk of readmission.

In this outbreak, 12 patients in intensive care units acquired a Chryseobacterium indologenes infection. Cultures from sinkholes and air samples were positive for C. indologenes. After removing wash basins, no new cases appeared. Sinkholes, potentially contaminated, can act as a reservoir for C. indologenes and other microorganisms. Thus, patients and equipment should be protected from sink splashes to avoid contamination.

Background: Social engagement (SE) has been consistently shown to improve survival among community-dwelling older people, but the evidence in nursing home residents is inconclusive and prone to short-term reverse causation and confounding by major health determinants. Our main objective was to study the potential causal effect of within-the-facility social engagement (SE) on long-term all-cause mortality in care home residents. Methods: A representative cohort of 382 nursing home residents in Madrid without severe physical and cognitive impairments at baseline was followed up for 10-year all-cause mortality. Standardized mortality curves for residents with low/null, moderate, and high levels of SE at baseline were estimated using Kaplan-Meier methods and spline-based survival models with inverse probability of exposure weights conditional on baseline sociodemographic characteristics, facility features, comorbidity, and disability. Standardized 5-year mortality risks and median survival times were compared across levels of SE. Results: The baseline prevalences of low/null, moderate, and high SE were 36, 44, and 20%, respectively. Compared with residents with low/null SE at baseline, the standardized differences (95% confidence intervals) in 5-year mortality risk were − 2.3% (− 14.6 to 10.0%) for moderately engaged residents and − 18.4% (− 33.8 to − 2.9%) for highly engaged residents. The median survival time increased by 0.4 (− 1.4 to 2.2) and 3.0 (0.8 to 5.2) years, respectively. Conclusion: Residents with high SE within the nursing home had an 18% lower 5-year mortality risk and a 3-year increase in their median survival, as compared with residents with similar health determinants but low/null SE. The development of adequate tailored intervention programs, addressed to increase SE in nursing home residents, could improve their long-term survival, in addition to expected gains in quality of life.

Introducción: Las infecciones relacionadas con la asistencia sanitaria (IRAS) son un problema de Salud Pública prioritario en España y constituyen un marcador de calidad asistencial. La vigilancia de las IRAS ayuda a conocer la epidemiología de estas infecciones para orientar la implementación de adecuadas medidas de prevención y control. Metodología: se han analizado los datos individualizados de pacientes de la encuesta de prevalencia del 2022 (EP-2022), aportadas por la coordinación nacional del EPINE (Estudio de Prevalencia de las Infecciones Nosocomiales en España) de la Sociedad Española de Medicina Preventiva, Salud Pública y Gestión Sanitaria (SEMPSPGS), como parte de los acuerdos establecidos con el Ministerio de Sanidad. Se han calculado prevalencias de pacientes con alguna IRAS y con algún antimicrobiano (ATM) y se han analizado las asociaciones entre factores de riesgo de pacientes y características de hospitales con la presencia de IRAS. Resultados: La prevalencia de pacientes con alguna IRAS fue 8,2% y la de pacientes con algún ATM, 46,4%. Pacientes varones, entre 61-75 años, con hipoalbuminemia, úlceras por presión, coma, cirugía, catéter urinario o intubados, con un estado basal con categoría McCabe de “enfermedad tardía o rápidamente fatal”, ingresados en hospitales de 650 camas o más o en hospitales de larga estancia presentaron prevalencias más altas. Conclusiones: La EP-2022 ha permitido conocer la epidemiología de las IRAS en los hospitales españoles e identificar pacientes con potenciales factores riesgo donde maximizar esfuerzos de prevención de las infecciones.
