Ear, nose and throat surgery among young Australian children

Tonsillectomy, adenoidectomy and myringotomy are the most common surgical procedures undergone by children. Medical opinion regarding the appropriateness of these procedures remains contentious, and considerable resources have been expended in the formulation and distribution of relevant practice guidelines. The impact of this surgery on the child, community and private and public health resources is considerable, yet there has been little examination of surgery rates and trends, or of the characteristics of children who undergo surgery. This thesis addressed five major questions regarding this surgery in New South Wales, Australia. The first three related to population rates: the level of surgery among NSW children, comparability with international rates, trends over time and the effect of guidelines. Comprehensive hospital data between 1981 and 1999 were analysed. Major findings were a higher myringotomy rate in NSW than reported internationally, the short-term effect of guidelines, and a major shift towards children having surgery at a younger age. The remaining questions asked whether children who had surgery differed from other children in their use of health services prior to surgery, and if so, whether their utilization reverted to the norm following surgery. Matched records of a population cohort of 6239 NSW children, born during January 1990, were extracted from Health Insurance Commission data, and their claims for medical services followed retrospectively from birth to 8 years. Children who had privately funded surgery were found to use more medical services than other children, and, most unexpectedly, this did not change following surgery. The results suggest potential non-clinical factors influencing this excess utilization. This is the first population study to examine health service utilisation by these children and it has identified an important new risk factor for surgery.
