Association of Positive Airway Pressure Use With Acute Care Utilization and Costs.

STUDY OBJECTIVES: The current value-based medical climate has led to scrutiny of all medical costs. Given the relationship between obstructive sleep apnea (OSA) and many significant comorbid medical conditions, treating patients with OSA via positive airway pressure (PAP) therapy might reduce health care expenditures. Our goal was to determine the relationship between PAP use and acute care utilization and costs. METHODS: This was a retrospective cohort study of adult patients who initiated PAP therapy after a diagnosis of moderate-severe OSA at a large integrated health system during 2014-2016. RESULTS: The study consisted of 1,098 patients, of which 60% were on PAP > 4 h/night for ≥ 70% of the nights. The average h/night were 5.3 (standard deviation 2.4). Increasing PAP usage was associated with reduced inpatient (rate ratio [RR] 0.92, 95% confidence interval [CI] 0.86-0.98) and overall acute care visits (RR 0.96, 95% CI 0.92-0.99). The linear relationships were supported by the threshold effects identified in the categorical adherence measures. No linear association was identified with emergency department visits and inpatient stays. However, lower number of emergency department visits (RR 0.78, 95% CI 0.62-0.98) and inpatient stays (RR 0.56, 95% CI 0.35-0.91) were observed among adherent (> 4 h/night for ≥ 70% of the nights) patients. CONCLUSIONS: PAP usage was linearly associated with reduced number of inpatient and overall acute care visits, and lower likelihood of having positive costs from these visits. PAP usage was also associated with less emergency department visits and inpatient stays when comparing adherent patients to less adherent patients.

Delaying Middle School and High School Start Times Promotes Student Health and Performance: An American Academy of Sleep Medicine Position Statement.

ABSTRACT: During adolescence, internal circadian rhythms and biological sleep drive change to result in later sleep and wake times. As a result of these changes, early middle school and high school start times curtail sleep, hamper a student's preparedness to learn, negatively impact physical and mental health, and impair driving safety. Furthermore, a growing body of evidence shows that delaying school start times positively impacts student achievement, health, and safety. Public awareness of the hazards of early school start times and the benefits of later start times are largely unappreciated. As a result, the American Academy of Sleep Medicine is calling on communities, school boards, and educational institutions to implement start times of 8:30 AM or later for middle schools and high schools to ensure that every student arrives at school healthy, awake, alert, and ready to learn.
