Frequency of provision of CPAP in the inpatient setting: an observational study : "CPAP provision in the inpatient setting".

Background: Little is known about the rates of provision of CPAP in inpatient settings. A single prior "data mining" study using diagnostic and procedural codes concluded that 6% of people with sleep apnea receive CPAP when in the hospital. The purpose of this study is to reexamine the frequency with which people who have an established diagnosis of sleep apnea receive therapy for it when they are admitted to the hospital for other reasons.
