Purpose: The objective of this study was to assess the impact of healthcare benefits on adherence to positive airway pressure (PAP) therapy in obstructive sleep apnea (OSA) patients.
Methods: Medical records of OSA patients at the Veterans Health Service Medical Center were retrospectively reviewed. OSA patients were assigned to two groups as the date of prescribing PAP: after (=Group A) and before (=Group B) July 1, 2018 when PAP therapy starts to be included in healthcare insurance coverage for OSA patients in South Korea. PAP adherence was compared over a 3-month period between the two groups; subjective improvement after therapy was evaluated using the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index scores. In addition, we evaluated a number of OSA patients who chose to start PAP therapy without healthcare benefit (from July 2018 to December 2018).
Results: Each of the 50 patients in the Group A and B exhibited PAP adherence rates of 82% and 26%, respectively (P < .001). Age did not affect PAP adherence in the Group A. The mean apnea-hypopnea index (from 36.7 to 1.34, P < .001) and ESS (from 7.6 to 5.6, P = .004) scores of patients in the Group A had significantly improved within the first three months. Twenty-three (23 out of 334, 6.9%) OSA patients did not have any healthcare insurance, but they medically needed PAP therapy. However, only one of the 23 patients began PAP treatment.
Conclusion: Short-term PAP adherence significantly improved after PAP therapy was included in healthcare insurance coverage.
