Health Effects of Identifying Patients with Undiagnosed Obstructive Sleep Apnea in the Preoperative Clinic: A Follow-up Study

The preoperative patients who were identified to have OSA and were compliant with CPAP use may have health benefits in terms of improved snoring, sleep quality, and daytime sleepiness. The CPAP compliant patients had a greater reduction in medication for comorbidities than the CPAP non-compliant or other treatment group. Timely diagnosis and treatment compliance may reduce symptoms of OSA and severity of associated comorbidities along with a reduction in medications.
