0445 Quality Of Sleep History In Hospitalized Patients Undergoing Sleep Apnea Screening

Introduction Obstructive sleep apnea (OSA) is a frequent cause of morbidity associated with hospitalization. Recently, we reviewed experience with an inpatient sleep screening program, finding a high proportion of OSA. It is well known that hospital and general medical histories often do not include sleep related histories. We explored the factors in the recorded histories associated with having an inpatient screening test. Methods Charts of 61 hospitalized adult patient who had undergone inpatient OSA screening (Morpheus ®) were reviewed. We hypothesized that patients in whom OSA screening was performed would have a high proportion of specific OSA related history recorded in the chart. Results The following symptoms/signs associated with OSA were found on chart review of 61 patients as follows: snoring: 20; excessive sleepiness: 15; witnessed apneas: 18; Mallampati score: 9; Stop-Bang: 12; Epworth Score: 4. At least one of these was recorded in only 23/61 patients. Among this group 45/61 patients had OSA (Apnea-Hypopnea Index greater than 5) on inpatient screening. In 33/61 a pulmonary or sleep consultant note was on the chart. The following did NOT predict having a positive sleep screening: having at least one sleep symptom/sign recorded, observed nocturnal desaturation, or observed hypercapnia. The following did predict OSA: past history of OSA (P=.014), having a pulmonary/sleep consultant note on the chart (p=.025), while a history of snoring was a borderline predictor (p=.053). Conclusion Documentation of sleep apnea related history is generally poor in hospitalized patients, even those have sleep apnea screening. Standardized screening tools are rarely used for inpatients. The reasons for OSA screening are not always clear. Protocols for hospitalized patients for screening for OSA should be standardized. Support (If Any) None
