Objective
To describe the contemporary epidemiology of paediatric adenotonsillectomy in an Australian setting, examine the incidence rate over 2010‐2015 and investigate factors associated with inter‐hospital transfer.
Design
Retrospective population‐based study.
Setting
Multicentre study in the state of Victoria, Australia.
Participants
From the Victorian Admitted Episodes Dataset, which included all patients aged 0‐19 years who underwent adenoidectomy and/or tonsillectomy in Victoria, Australia between 2010 and 2015.
Main Outcome Measures
Annual incidence rate, hospital volume, inter‐hospital transfer.
Results
Between 2010 and 2015, 59 008 patients underwent 61 281 procedures, with highest number performed in males (52.7%), children aged under 10 years (73.5%) and in the higher socioeconomic groups (24.6% in quintile 4 and 23.2% in quintile 5). Seventy‐five cases (0.12%) resulted in inter‐hospital transfer, which was significantly associated with young age (under 5 years). More than a third of hospitals (35.7%) performed an average rate of <1 procedure per week. Hospital volume was not associated with risk of inter‐hospital transfer. The incidence rate of adenotonsillectomy procedures significantly increased over the study period (P < .001), driven by a significant increase in the rate of surgery performed for obstructive symptoms (P < .001).
Conclusions
The rate of adenoidectomy/tonsillectomy procedures is rising, with a higher proportion being performed in socioeconomically advantaged patients. This raises concerns regarding healthcare access, given the literature supporting higher rates of obstructive sleep‐disordered breathing and sore throat in lower socioeconomic groups. A third of hospitals performed small numbers of procedures, but we found no association between hospital volume and inter‐hospital transfers.
