Background and Objectives: Positive airway pressure (PAP) is effective at reducing the number of complications in patients with obstructive sleep apnea (OSA). To the best of our knowledge, no cost-effectiveness analysis of PAP has been conducted in Korea.
Subjects and Method: We classified subjects into two groups, those with moderate-to-severe OSA who used PAP after polysomnography (PAP treatment group) and those who did not receive a diagnosis and treatment (control group), and compared their medical expenses over a period of 10 years. The incidence rate of common complications and accidents (coronary heart disease, heart failure, stroke, depression, diabetes, vehicular accidents, and work-related accidents) with or without PAP was adopted through a literature review. The average medical expenses for treating each complication and accident were found by searching several databases. The analysis consisted of a payer’s perspective and a societal perspective.
Results: The incidence of all complications was higher in the control group than in the PAP treatment group. However, since the absolute incidence rate was not high in either group and medical expenses in Korea are low, the expected treatment cost was not high. In contrast, the PAP rental fee was relatively high. To obtain 1 unit of disability-adjusted life year, it costs 40,873,288 won from the payer’s perspective and 31,791,810 won from the societal perspective.
Conclusion: PAP treatment reduces patient complications and extends their lifespan, but costs must be considered.
