Intussusception in Australia: Epidemiology prior to the introduction of rotavirus vaccine

Abstract

Objectives: To describe the incidence rate and clinical outcomes of intussusception in Australia in children aged <24 months prior to the use of rotavirus vaccines in Australia, and to explore associations between patient characteristics and outcomes in children with intussusception. Methods: This study used Australian national hospital discharge data on intussusception from July 2000 to June 2006 for children aged 2 days and the need for surgical intervention). Results: The overall incidence rate of intussusception was 5.4 per 10,000 child-years in children under 24 months (95%CI 5.17-5.70). There was a declining rate over the study period (p<0.001). Age at time of intussusception was stron..
