New Screening Questionnaire to Assess Obstructive Sleep Apnea in a Population Attending a Multidisciplinary Craniofacial Pain Center.
Abstract: Purpose: The objective of this research study was to propose a new screening questionnaire to assess obstructive sleep apnea (OSA) in a group of subjects attending a multidisciplinary Craniofacial Pain Center. Methods: This was a cross-sectional clinical study designed to evaluate the use of a new screening questionnaire (NQ) consisting of 15 items based on literature and standard of car... read moree clinical evaluation at a multidisciplinary craniofacial pain center in a dental school. The new questionnaire was compared with a supplemental questionnaire (SQ) previously validated ("STOP" questionnaire). Cross tabulation, sensitivity, specificity, positive and negative predictive values were obtained with standard methods, comparing the questionnaires to the results from at-home sleep studies using a portable sleep monitor which determined the presence of obstructive sleep apnea based on the apnea hyponea index (AHI) and respiratory disturbance index (RDI). The Cronbach alpha was calculated for each questionnaire as a measurement of internal reliability. Results: The NQ was administered to 50 subjects. 70% were women. The study population had a mean age of 46.1 years (SD 12.0), mean body weight mean of 163.0 pounds (SD 36.0), mean BMI of 27 (SD 6.0), and mean neck size of 15.0 inches (SD 2.0). Home sleep study was performed and the presence of OSA was defined based on both AHI and RDI, using a cutoff of 5. According to AHI, 54% of the subjects were identified as having OSA; according to RDI, 88% were identified as having OSA. Three items from the NQ 4,7,13showed statistical significant associations (P < . 005) with AHI-defined OSA. No items were statistically significantly associated with RDI defined OSA. Conclusions: The findings from this study showed statistical significant value from three items on screening for obstructive sleep apnea. These items may be useful when combined with the supplemental questionnaire to create a new modified screening questionnaire to identify subjects at risk of obstructive sleep apnea.
