Skirrow H, et al. - Researchers conducted this retrospective population-based birth cohort study to estimate the risk of subsequent respiratory hospital admissions in children under 5 years in England following bronchiolitis admission in infancy. They built a birth cohort of 613,377 infants born between April 1, 2007, and March 31, 2008, followed up until aged 5 years by linking Hospital Episode Statistics admissions data. Using Cox proportional hazard regression, the risk of respiratory hospital admission due to asthma, wheezing and lower and upper respiratory tract infections in infants who had been admitted for bronchiolitis were compared with those who had not. According to findings, hospital admission for bronchiolitis in infancy was linked to a threefold to fivefold risk of subsequent respiratory hospital admissions from asthma, wheezing and respiratory infections. Data reported that 1 in 5 infants with bronchiolitis hospital admissions will have a subsequent respiratory hospital admission by age 5 years.
