Abstract

Study Objectives Obstructive sleep apnea (OSA) has been historically underdiagnosed and may be associated with grave perioperative complications. The ASA and American Academy of Sleep Medicine recommend OSA screening prior to surgery; however, only a minority of patients are screened. The objective of this study was to determine the proficiency of anesthesiologists, otolaryngologists, and internists at predicting the presence of OSA by visual photographic analysis without the use of a computer program to assist, and determine if prediction accuracy varies by provider type. Design Prospective case series Setting Tertiary care hospital-based academic center Patients Fifty-six consecutive patients presenting to the sleep laboratory undergoing polysomnography had frontal and lateral photographs of the face and torso taken. Interventions Not applicable. Measurements Polysomnography outcomes and physician ratings. An obstructive apnea hypopnea index (oAHI) ≥ 15 was considered "positive." Twenty anesthesiologists, 10 otolaryngologists, and 11 internists viewed patient photographs and scored them as OSA "positive" or "negative" before and after being informed of patient comorbidities. Main Results Nineteen patients had an oAHI <15, 18 were ≥ 15 but <30, and 19 were ≥ 30. The mean oAHI was 28.7 ± 26.7 events/h (range, 0-125.7), and the mean body mass index was 34.1 ± 9.7 kg/m2 (range, 17.4-63.7). Overall, providers predicted the correct answer with 61.8% accuracy without knowledge of comorbidities and 62.6% with knowledge (P
