Changes in healthcare utilisation for paediatric tonsillectomy and adenoidectomy in the Netherlands: a population-based study.

Abstract

ObjectivesTonsillectomy and adenoidectomy in children are controversial subjects with large regional variation in surgical rates, partly explained by cultural differences and lack of high‐quality evidence on indications for surgery. A quality of care cycle was executed on this topic in the Netherlands. The objective of this study was to estimate changes in healthcare utilisation for paediatric tonsil surgery in the Netherlands.MethodsPopulation‐based data on tonsillectomies and adenoidectomies in children up to age 10 were retrieved retrospectively from Dutch administrative databases between 2005 and 2018. A change point analysis was performed to detect the most pivotal change point in surgical rates. We performed univariate analyses to compare surgical patients’ characteristics before and after the pivotalpoint . Impact on healthcare budget and societal costs were estimated using current prices and data from cost‐effectiveness analyses.ResultsThe annual number of adenotonsillectomies reduced by 10 952 procedures (−39%; from 129 per 10 000 children to 87 per 10 000 children) between 2005 and 2018, and the number of adenoidectomies by 14 757 procedures (−49%; from 138 per 10 000 children to 78 per 10 000 children). The most pivotal change point was observed around 2012, accompanied by small changes in patient selection for surgery before and after 2012. An estimated €5.3 million per year was saved on the healthcare budget and €10.4 million per year on societal costs.ConclusionThe quality of care cycle resulted in fewer operations, with a concomitant reduction of costs. We suggest that part of these savings be invested in new research to maintain the quality of care cycle.
