Comparing a wrist device and sleep study for diagnosing sleep apnea in military personnel
Updated
Abstract
The prevalence of obstructive sleep apnea (OSA) among active-duty military personnel was found to be 63.5%.
- PAT-based home sleep apnea testing (HSAT) overdiagnosed 27.4% and underdiagnosed 46.6% of patients with OSA.
- More than half of the patients (55.8%) experienced changes in OSA severity classification after confirmatory polysomnography (PSG).
- Concordance between PAT-based HSAT and PSG for OSA severity classification was observed in 53.4% for absent, 40.5% for mild, 28.6% for moderate, and 40.0% for severe OSA.
- The proposed cutoff score for diagnosing OSA using the PAT-based HSAT was 9.0 events/h, with a sensitivity of 52% and specificity of 83%.
- There was an unacceptable degree of agreement between PAT-based HSAT-derived and PSG-derived apnea-hypopnea indices.
