Admission to hospital for bronchiolitis in England: trends over five decades, geographical variation and association with perinatal characteristics and subsequent asthma

BackgroundAdmission of infants to hospital with bronchiolitis consumes considerable healthcare resources each winter. We report an analysis of hospital admissions in England over five decades.MethodsData were analysed from the Hospital In-Patient Enquiry (HIPE, 1968–1985), Hospital Episode Statistic...
