In a paper published in the journal PLOS ONE . Jo Murray and colleagues examined the timing and duration of hospital admissions from respiratory syncytial virus (RSV) bronchiolitis among term and preterm infants in England and to identify risk factors for admission. We carried out a population-based birth cohort with follow-up to age 1 year, using the Hospital Episode Statistics (HES) database using data from 71 hospitals across England. We identified 296618 individual birth records from 2007/08 and linked to subsequent hospital admission records during the first year of life. In our cohort, there were 7189 hospital admissions with a diagnosis of bronchiolitis, 24.2 admissions per 1000 infants under 1 year (95% CI 23.7–24.8), of which 15% (1050/7189) were born preterm (47.3 bronchiolitis admissions per 1000 preterm infants (95% CI 44.4–50.2)). The peak age group for bronchiolitis admissions was infants aged 1 month and the median was age 120 days (IQR = 61–209 days). The median leng...
