Implementation of an Obstructive Sleep Apnea Screening Program at an Overseas Military Hospital

www.aana.com/aanajournalonline Anesthesia providers and surgeons do poorly at consistently identifying patients with obstructive sleep apnea (OSA) without use of screening tools. Aims of this evidence-based-practice project were to determine whether educating nurses about OSA and incorporating the STOP-BANG Questionnaire into preoperative forms was associated with an increased identification of patients with suspected OSA and an increased frequency of nurse-generated anesthesia consultation for OSA. A retrospective chart review of 100 consecutive records over a 1-month period using the STOP-BANG Questionnaire criteria was completed before and after implementation of the education and screening program at US Naval Hospital Okinawa, Japan. A STOPBANG Questionnaire score of 3 or higher indicated high risk of OSA. Descriptive and inferential statistics were used to analyze results. Two hundred charts were reviewed. The prevalence of a STOP-BANG score of 3 or more increased from 5% to 21% after program implementation (P = .001). The frequency of anesthesia consultation for known or suspected OSA by our nursing staff increased from 5% to 26% after implementation (P = .0001). After this educational intervention with preoperative nurses and redesign of preoperative forms to incorporate the STOP-BANG Questionnaire, an increased proportion of patients at high risk of OSA were identified.
