Epidemiology of hospitalizations caused by mumps in the general population in Spain (1997–2006)

Abstract

Mumps is a benign infectious condition, but when it affects adults it may cause serious complications that require hospitalization with a high cost and that may lead to permanent sequelae. The aim of this study was to estimate the incidence of hospitalization for mumps in Spain from 1997 to 2006. A retrospective epidemiological study was made using the data of the Spanish National hospital Discharge database Minimum Basic Data Set (MBDS) for yrs 1997–2006. We selected all those patients with code 072 for any diagnosis position (Clinical Modification of the International Classification of Diseases: ICD-9-CM), and estimated the incidence of hospitalization, length of stay, in hospital mortality and associated costs. Hospitalization for mumps was registered in 1733 cases, equating to an overall annual hospitalization rate of 0.423 per 100000 inhabitants. The mean length of the hospital stay was 5 days (interquartile range 3–9). There were 58 deaths in the study period. The mean cost per patient hospitalized for mumps was 2,572 €. High levels of immunization coverage are required to reduce the incidence of mumps, and prevent hospitalization from, and outbreaks with, this disease.
