Interstate variation within a five-state health system: Polysomnography prior to tonsillectomy in trisomy 21 patients

Objectives: Since 2011, the American Academy of Otolaryngology – Head and Neck Surgery Clinical Practice Guidelines have recommended polysomnography (PSG) prior to tonsillectomy in children with Down syndrome (DS). The purpose of this study was to determine adherence to guidelines recommending polysomnography before tonsillectomy for children with DS and sleep-disordered breathing among pediatric otolaryngologists. Methods: A one-year quality assurance retrospective review was conducted at four hospitals within one pediatric health system to identify children with a diagnosis of DS who underwent a tonsillectomy with or without adenoidectomy from January 1, 2018, to December 31, 2018. De-identified data related to age, sex, BMI, procedure type, and preoperative PSG were collected and examined. Results: The rate of PSG prior to tonsillectomy was 90.4% (66 of 73) among patients with DS. 51.6% of PSG studies were performed within 90 days before surgery, and 92.2% (59 of 64) of PSG studies were performed within one year before surgery. 33% of patients who did not undergo PSG also were obese or under age two years. The most common reason for not obtaining a PSG prior to tonsillectomy was that either the provider or parent felt the patient would not tolerate it. There was no variance from guidelines by age, sex, and procedure type. Conclusions: Polysomnography for children with DS prior to tonsillectomy is achieved greater than 90% of the time in a multistate pediatric health system. Broader assessment across the nation and future studies regarding the timing of PSG before tonsillectomy are warranted.
