PAP therapy and readmission rates after in-hospital laboratory titration polysomnography in patients with hypoventilation.

Study Objectives: Hypoventilation associated with sleep-disordered breathing in inpatients is associated with higher risk of morbidity, hospitalizations, and death. In-hospital titration polysomnography qualifies patients for positive airway pressure (PAP) therapy and optimizes settings, but impact is unknown. This study describes a process for in-hospital sleep testing and evaluates subsequent PAP adherence and readmission.
