Treatment compliance in patients lost to follow-up after polysomnography.

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.

Factors associated with noncompliance to treatment with positive airway pressure.

Objective: To identify risk factors that may predispose patients with a diagnosis of obstructive sleep apnea (OSA) to fail treatment with positive airway pressure (PAP) owing to noncompliance.

Design: Retrospective medical chart review.

Setting: Academic tertiary care center.
