Utilization of healthcare resources in obstructive sleep apnea syndrome : a 5- year follow-up study in men using CPAP

Patients with untreated obstructive sleep apnea syndrome (OSAS) have higher healthcare utilization than matched controls. However, the long-term impact of continuous positive airway pressure (CPAP) use on healthcare utilization is unknown. Retrospective observational cohort study. There were 342 eli...

Description
Summary:Patients with untreated obstructive sleep apnea syndrome (OSAS) have higher healthcare utilization than matched controls. However, the long-term impact of continuous positive airway pressure (CPAP) use on healthcare utilization is unknown. Retrospective observational cohort study. There were 342 eligible men with OSAS and matched controls on whom there were utilization data for 5 years prior to initial OSAS diagnosis and for the 5 years on CPAP treatment of the cases. Patients were treated with CPAP. Patients with OSAS were typical cases (mean +/- SD): age, 48.2 +/- 0.6 years; body mass index, 35.6 +/- 0.4 kg/m2; Epworth Sleepiness Scale score, 14.2 +/- 0.3; apnea-hypopnea index, 47.1 +/- 1.8 events per hour. The number of physician visits were higher by 3.46 +/- 0.2 (95% confidence interval [CI]: 2.57 to 4.36) in cases in the year before diagnosis, compared with the fifth year before diagnosis, then decreased over the next 5 years by 1.03 +/- 0.49 (95% CI: -1.99 to -0.07)(P
