Study Validates P-SAP Score in Predicting Obstructive Sleep Apnea Prior to Surgery

Researchers at the University of Michigan in Ann Arbor developed a perioperative sleep apnea prediction score based on independent clinical predictors of OSA to diagnose patients prior to surgery, according to a recent study published in the April issue of Anesthesia & Analgesia.

OSA is a largely underdiagnosed and common condition, which is important to diagnose because it has implications in perioperative management, according to the study. Researchers derived the following independent predictors of OSA:  age over 43 years, male gender, obesity, history of snoring, diabetes mellitus Type 2, hypertension, thick neck, modified Mallampati class 3 or 4 and reduced thyromental distance.

The P-SAP score was determined in 43,576 adult patients, 3,884 (7.17 percent) of whom had a diagnosis of OSA. Researchers found the P-SAP scoring system to demonstrate dependable accuracy across mild to severe disease, according to the study.
