PURPOSE: 1)To determine the point prevalence of at risk (for OSA) patients in a tertiary care hospital2)To determine how many of these have had a sleep study for evaluation3)To determine how many patients have been diagnosed with OSA4)To determine how OSA was being treated in the diagnosed patients.
METHODS: A single day survey was conducted of all inpatients. Patients were excluded if they were intubated, on sedatives or had altered mental status. Risk of OSA was determined using STOP and STOP-BANG questionnaire.
RESULTS: 195 patients were surveyed. 115 (59%) were male and 28 (14.4%) had a BMI > 35. 116 (59.5%) admitted to snoring, 114 (58.5%) complained of tiredness, 42 (21.5%) had witnessed apneas, 110 (56.4%) had high blood pressure, 159 (81.5%) were older than 50 years and 99 (50.8%) had a neck circumference > 40 cm. 127 (65%) patients classified as high risk based on STOP questionnaire (>/= 2 positive responses) and 157 (80.5%) were high risk per STOP-BANG questionnaire (>/= 3 positive responses). Only 41 patients had been evaluated with a sleep study and 31 of these were diagnosed with OSA. 17 patients (54.8%) were using CPAP, 13 (41.9%) were not on treatment and 1 (3.2%) patient had surgery for OSA.
CONCLUSION: 1)A significant number of hospitalized patients are at risk for OSA2)Very few of these patients have had a sleep study for evaluation3)Of those diagnosed with OSA, a large proportion are not on any treatment due to intolerance to CPAP.
CLINICAL IMPLICATIONS: 1)Undiagnosed OSA may be associated with increased risk of complications in hospitalized patients2)Screening and evaluation for OSA in high risk inpatients should be considered as it may help reduce the burden of undiagnosed OSA.
