Abstract
Several models aimed at screening for obstructive sleep apnea (OSA) have been published, and most of these are based on questions containing clinical, demographic, and anthropometric features previously identified as OSA risk factors. Here, our main objective was to review the usefulness of some of these screening tools and delineate their performance when attempting to identify subjects at risk for OSA. We evaluated some of the most cited screening tools including Sleep Apnea Clinical Score, Berlin and STOP-Bang questionnaires, Four-Variable Screening Tool, NoSAS score, and the Epworth Sleepiness Scale. Analysis of the predictive performance of the different tools is influenced by the sleep test used, the type of population studied, and the threshold of the apnea/hypopnea index used for OSA diagnosis. Nowadays, it would appear that the most employed screening instrument is the STOP-Bang questionnaire. It is a mnemonic method with eight questions dichotomized into yes-or-no responses and exhibits high sensitivity at all levels of OSA severity while also having been widely validated in several different populations.
