Abstract

BACKGROUND: The purpose of this study was to determine the volume of three complex paediatric procedures at the tertiary care centres in Ontario over the last 20 years in three disciplines, analyze outcomes and explore the possibility of an outcome volume relationship.

METHODS: A population based cohort study of patients undergoing TEF repair, Pyeloplasty and V-P shunt insertion at 4 paediatric centres in Ontario between 1993 and 2013 was carried out. Administrative data sets were linked using unique encoded identifiers and analyzed at the Institute for Clinical Evaluative Sciences (ICES).

RESULTS: In TEF repair and Pyeloplasty, there was significant difference in hospital volume between institutions and no significant difference in main outcome–reoperation rate between them. The data for VPS need to be completed.

CONCLUSIONS: This study demonstrated that although the institutional volume and surgeon volume is different, the reoperation rate between institutions is similar in tertiary paediatric Ontario centres.
