Assessment of screening tests for obstructive sleep apnoea syndrome in pre-operative surgical patients

Objective: To determine excessive daytime sleepiness (EDS), as a major symptom of obstructive sleep apnea (OSA), in preoperative surgical patients by applying Croatian version of Epworth Sleepiness Scale (ESS), and to test their risk for OSA using STOP and STOPBANG questionnaires. Methods: The observational cross-sectional study included 1.348 consecutive patients (737 females) in Pre-anesthesia Evaluation Clinic aged 18 years or older without, previously diagnosed OSA. Results: STOP positive patients were older [62 (20–88) versus 50 (18–89) yrs, P < 0.001], had greater BMI (28.5 ± 4.2 versus 25.7 ± 4.3 kg/m, P < 0.001), neck circumference (40.8 ± 4.1 versus 39.2 ± 4.2 cm, P < 0.001), and greater ASA physical status (chi2 = 33.03, P < 0.001) compared to STOP negative patients. Also, STOP positive patients had greater ESS scores compared with STOP negative patients (5.25 ± 3.8 versus 3.91 ± 3.1, P < 0.001). STOPBANG positive patients had greater ASA physical status than STOPBANG negative patients (chi2 = 37.96, P < 0.001). Also, STOPBANG positive patients had greater ESS scores compared with STOP-BANG negative patients (4.55 ± 3.5 versus 3.97 ± 3.1, P = 0.003). The average ESS score in all subjects was 4.2 ± 3.3. In male subjects it was 3.97 ± 3.1, and in females 4.46 ± 3.5 (P = 0.012). More male patients reported snoring (P < 0.001), and that someone had observed them to have stopped breathing during sleep (P = 0.017), whereas more female patients reported being tired (P < 0.001). Conclusion: EDS measured using the ESS score was significantly greater in the STOP and the STOP-BANG positive patients compared with no-risk patients. The Croatian version of the ESS seems to be better correlated with the STOP than with the STOPBANG questionnaire. All tested screening tools may be useful in testing risk for OSA in preoperative surgical patients.
