Objectives:
Studies on positive airway pressure (PAP) compliance typically focus only on patients who returned for follow-up. In this study, we examined patients who failed to follow-up after their initial polysomnogram (PSG) and PAP titration to determine their treatment status in terms of PAP usage.
Study Design:
On retrospective chart review, we identified 57 patients who, based on PSG findings and symptoms, required the use of PAP but failed to follow-up after titration. Twenty-five of these patients were successfully contacted and agreed to an interview.
Results:
Only 7 (28%) patients were using PAP on a regular basis. The remaining 18 (72%) patients were noncompliant.
Conclusions:
A significant proportion (24%) of OSA patients who required treatment with PAP were lost to follow-up after polysomnography. This group of patients has previously been ignored in the literature. We showed in this study that majority (72%) of these patients were not being treated adequately for OSA.
