Utilization of the STOP-Bang Questionnaire as a Standardized Screening Tool for Obstructive Sleep Apnea in Veteran Administration Surgical Patients.

Purpose: Obstructive sleep apnea (OSA) affects an estimated 20% of the adult surgical population. Veteran patients have many characteristics consistent with OSA, but lack of standardized screening results in decreased detection of patients at risk for OSA.

Design: Pre-post implementation design.
