Undiagnosed obstructive sleep apnea (OSA) may adversely impact surgical patients and can lead to increased morbidity and mortality during the perioperative period, especially among the geriatric patient population (Chung et al. 2008, 2012, 2014; McDonald et al., 2018; Zietlow et al., 2018; Singh et al., 2012). The setting of this quality improvement project was a preoperative anesthesia and geriatric evaluation clinic housed within a 957-bed tertiary academic affiliated hospital. The sample included 45 patients who met the criteria established for surgery and OSA screening preoperatively. Nine patients (20.0%) were assessed as low risk (Stop-bang [SB] score </=2) for OSA, and 36 patients (80.0%) had a prior diagnosis from an ICD-9/10 code or a SB score >/= 3 indicative of high-risk for OSA. The retrospective utilization of a modified SB screening on charts that did not receive a clinical OSA evaluation (n = 52) detected 23 (44.2%) patients who were considered high-risk for OSA but were not identified prior to surgery. The SB questionnaire is underutilized, and patients’ OSA is often unidentified prior to surgery.
