RESUMO

Background: Understanding the hospital impact of influenza requires enriching epidemiological surveillance registries with other sources of information. The aim of this study was to determine the validity of the Hospital Care Activity Record – Minimum Basic Data Set (RAE-CMBD) in the analysis of the outcomes of patients hospitalised with this infection. Methods: Observational and retrospective study of adults admitted with influenza in a tertiary hospital during the 2017/2018 and 2018/2019 seasons. We calculated the concordance of the RAE-CMBD with the influenza epidemiological surveillance registry (gold standard), as well as the main parameters of internal and external validity. Logistic regression models were used for risk adjustment of in-hospital mortality and length of stay. Results: A total of 907 (97.74%) unique matches were achieved, with high inter-observer agreement (ƙ=0.828). The RAE-CMBD showed a 79.87% sensitivity, 99.72% specificity, 86.71% positive predictive value and 99.54% negative predictive value. The risk-adjusted mortality ratio of patients with influenza was lower than that of patients without influenza: 0.667 (0.53-0.82) vs. 1.008 (0.98-1.04) and the risk-adjusted length of stay ratio was higher: 1.15 (1.12-1.18) vs. 1.00 (0.996-1.001). Conclusion: The RAE-CMBD is a valid source of information for the study of the impact of influenza on hospital care. The lower risk-adjusted mortality of patients admitted with influenza compared to other inpatients seems to point to the effectiveness of the main clinical and organisational measures adopted. (AU)


Objetivos: Conocer el impacto hospitalario de la gripe requiere enriquecer los registros de vigilancia epidemiológicos con otras fuentes de información. El objetivo de este estudio fue determinar la validez del Registro de Actividad de Atención Especializada – Conjunto Mínimo Básico de Datos (RAE-CMBD) en el análisis de los resultados asistenciales de los pacientes hospitalizados con esta infección. Métodos: Estudio observacional retrospectivo de los adultos ingresados con gripe en un hospital terciario durante las temporadas 2017/2018 y 2018/2019. Se calculó la concor-dancia del RAE-CMBD con el registro de vigilancia epidemiológica de gripe (estándar de referencia), así como los principales parámetros de validez interna y externa. Se utilizaron modelos de regresión logística para el ajuste por riesgo de la mortalidad intrahospitalaria y duración de la estancia. Resultados: Se lograron 907 (97,74%) emparejamientos únicos, con una concordancia interobservadores elevada (ƙ=0,828). El RAE-CMBD mostró una sensibilidad del 79,87%, especificidad del 99,72%, valor predictivo positivo del 86,71% y negativo del 99,54%. La razón de mortalidad ajustada por riesgo de los pacientes con gripe fue menor que la de los pacientes sin gripe: 0,667 (0,53–0,82) vs. 1,008 (0,98–1,04) y la razón de duración de la estancia ajustada por riesgo, mayor: 1,15 (1,12–1,18) vs. 1,00 (0,996–1,001). Conclusiones: El RAE-CMBD es una fuente de información válida para el estudio del impacto de la gripe en la atención hospitalaria. La menor mortalidad ajustada por riesgo de los pacientes ingresados con gripe respecto de los demás ingresados, parece apuntar a la efectividad de las principales medidas clínicas y organizativas adoptadas.

RESUMO

OBJECTIVE: This study presents information on the evolution of severe cases of SARS-CoV-2 infection that required hospitalization since the beginning of vaccination in Spain. The objective was to know the impact of vaccination against COVID-19 on the hospitalization of patients with SARS-CoV-2 infection, hospital mortality and readmissions for this cause, and to describe the characteristics of vaccinated patients who required admission. METHODS: A retrospective, observational epidemiological study was conducted of all patients admitted with SARS-CoV-2 infection confirmed by a diagnostic test for active infection (PDIA) in a tertiary hospital, from January 2021 to June 2021. The incidence of admissions was calculated based on the vaccination status of the patients and age groups at different times according to the progress of the strategy of vaccination COVID-19. RESULTS: Between December 27, 2020 and June 30, 2021, 1,308 patients with positive PDIA were admitted to the University Hospital of Salamanca, of which 1,167 (89.2%) were not vaccinated, 129 (9.9%) had received one dose of vaccine and 12 (0.9%) were fully vaccinated. Of the latter, none were admitted to the ICU and 2 died. CONCLUSIONS: Vaccination against COVID-19 has contributed to the decrease in hospitalizations, since February 2021, of older and institutionalized people. Fully vaccinated people have a lower risk of admission to the ICU and death. These data, together with the information available on recent cases of new SARS-CoV-2 infections in unvaccinated young people, are in favor of achieving high vaccination coverage of the entire population in the shortest possible time.


OBJETIVO: Este estudio presenta información sobre la evolución de los casos graves de infección SARS-CoV-2 que requirieron hospitalización desde el inicio de la vacunación en España. El objetivo fue conocer el impacto de la vacunación frente a COVID-19 sobre la hospitalización de pacientes con infección SARS-CoV-2, la mortalidad intrahospitalaria y los reingresos por esta causa, y describir las características de los pacientes vacunados que precisaron ingreso. METODOS: Se realizó un estudio epidemiológico observacional retrospectivo, de todos los pacientes ingresados con infección por SARS-CoV-2 confirmada mediante una prueba de diagnóstico de infección activa (PDIA) en un hospital de tercer nivel, de enero de 2021 a junio de 2021. Se calculó la incidencia de ingresos en función del estado vacunal de los pacientes y grupos de edad en diferentes momentos según el avance de la campaña de vacunación. RESULTADOS: Entre el 27 de diciembre de 2020 y el 30 de junio de 2021 ingresaron en el Hospital Universitario de Salamanca 1.308 pacientes con PDIA positiva, de los cuales 1.167 (89,2%) no estaban vacunados, 129 (9,9%) habían recibido una dosis de vacuna y 12 (0,9%) estaban completamente vacunados. De estos últimos, ninguno ingresó en UCI y 2 fallecieron. CONCLUSIONES: La vacunación frente a COVID-19 ha contribuido al descenso de las hospitalizaciones desde el mes de febrero de 2021, sobre todo en personas mayores e institucionalizadas. Las personas completamente vacunadas parecen tener menor riesgo de ingreso en UCI y fallecimiento. Estos datos, junto con la información disponible de los casos recientes de nuevas infecciones por SARS-CoV-2 en personas jóvenes no vacunadas, están a favor de conseguir una cobertura vacunal elevada de toda la población en el menor tiempo posible.

RESUMO

BACKGROUND: The high morbidity and mortality caused by influenza viruses translate into a great impact on specialized health care. Apart from the annual vaccination, the relevance of other measures to prevent and control this infection is unknown. The objective of our research was to determine the importance of a real-time surveillance system to establish early extended transmission precautions. METHODS: Quasi-experimental before-and-after study comparing the influenza cases detected in hospitalized adults during the 2016/2017 season (264 patients) with those detected after the implementation of a real-time surveillance system in the 2017/2018 season (519 patients). The improvements included early microbiological diagnosis, immediate communication of results, constant updating of patient information, coordination among professionals, periodic surveillance of the adequacy of preventive measures, and greater control of roommates. The effectiveness of the intervention was determined from the nosocomial infection rate in each season. RESULTS: After the real-time surveillance system for influenza was implemented, patients with early microbiological diagnosis and immediate isolation increased significantly (13.7% vs 68.2%; P < .001). In addition, nosocomial infections decreased from 17% to 9.2% (P = .001) and overall hospital stay was significantly reduced. Assuming that the entire effect was due to the intervention, the absolute risk reduction was 7.8% and number needed to treat was 12.8. CONCLUSION: The results in our study reveal the impact of nosocomial transmission of influenza virus in a tertiary hospital and highlight the need to supplement traditional strategies with novel methodologies such as modern surveillance systems based on early diagnosis, close case monitoring, and coordination among professionals.
