Pediatric sleep studies: when and how often are they necessary?

Impact of AAO-HNS Guideline on Obtaining Polysomnography Prior to Tonsillectomy for Pediatric Sleep-Disordered Breathing

OBJECTIVE

To assess the impact of the 2011 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guideline on practice patterns in obtaining preadenotonsillectomy (AT) polysomnography (PSG) for pediatric sleep-disordered breathing (SDB).

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary children's hospital.

SUBJECT AND METHODS

The study population included all patients referred to our pediatric otolaryngology clinic for consideration of AT for SDB during two 12-month time periods: before (2010-2011) and after (2015-2016) publication of the 2011 AAO-HNS guideline. Demographic, insurance, comorbidity, and Pediatric Sleep Questionnaire (PSQ) variables were assessed for association with pre-AT PSG using bivariate and multivariate logistic regression analysis.

RESULTS

A greater percentage of patients underwent pre-AT PSG in 2015-2016 vs 2010-2011 (30% vs 22%, P = .001). On multivariate analysis, presence of neuromuscular disorder was the only predictor associated with pre-AT PSG in 2010 to 2011 (odds ratio [OR], 3.00; 95% CI, 1.10, 8.06; P = .03). Presence of neuromuscular disorder (OR, 2.54; 95% CI, 1.51, 4.29; P < .0001), craniofacial anomaly (OR, 2.32; 95% CI, 1.20, 4.50; P = .013), or Down syndrome (OR, 3.45; 95% CI, 1.54, 7.72; P = .003) was associated with pre-AT PSG in 2015 to 2016. Positive PSQ screen was significantly associated with decreased odds of pre-AT PSG in both time periods.

CONCLUSION

After publication of the 2011 AAO-HNS guideline, there was a significant but modest increase in pre-AT PSG utilization in children with SDB and high-risk comorbidities at our institution, consistent with AAO-HNS guideline recommendations. However, overall guideline adherence remains low and may reflect limitations in PSG testing capacity.

Obstructive Sleep Apnea and Surgery: Quality Improvement Imperatives and Opportunities

Obstructive sleep apnea (OSA) is more common in surgical candidates than in the general population and may increase susceptibility to perioperative complications that range from transient desaturation to catastrophic injuries. Understanding the potential impact of OSA on patients' surgical risk profile is of particular interest to otolaryngologists, who routinely perform airway procedures-including surgical procedures for treatment of OSA. Whereas the effects of OSA on long-term health outcomes are well documented, the relationship between OSA and surgical risk is not collinear, and clear consensus on the nature of the association is lacking. Better guidelines for optimization of pain control, perioperative monitoring, and surgical decision making are potential areas for quality improvement efforts. Many interventions have been suggested to mitigate the risk of adverse events in surgical patients with OSA, but wide variations in clinical practice remain. We review the current literature, emphasizing recent progress in understanding the complex pathophysiologic interactions noted in OSA patients undergoing surgery and outlining potential strategies to decrease perioperative risks.
