Invasive pneumococcal disease in children. A retrospective review (1993–2004) supporting universal immunization

Abstract

The objectives of this study were to describe a series of children with invasive pneumococcal disease (IPD), evaluate the proportion with defined risks for pneumococcal disease and to assess the impact of the new UK pneumococcal vaccination schedule in preventing IPD. We conducted a review of case notes of children aged 0–16 years admitted to a large district general/teaching hospital in East Birmingham from September 1993-December 2004. Fifty-six children were identified with IPD; case notes were available for 54 children (55 episodes). The median age at diagnosis was 15 months (inter-quartile range 8–37.5 months). Only 14 (26%) had pre-existing risk factors for developing IPD. A significant age difference was found between those with co-existing risk factors and those without (median 37 months vs. 11 months; P
