Background: The purpose of this study is to determine if there is a relationship between a person’s Mallampati score and their scores on the Berlin Questionnaire and Epworth Sleepiness Scale. The Berlin Questionnaire and Epworth Sleepiness Scale are currently used as prescreening tools for persons who may suffer from sleep disorders. The Berlin Questionnaire (10 questions) is used to identify persons at risk for sleep apnea syndrome and the Epworth Sleepiness Scale (8 questions) is used to determine the level of a person’s daytime sleepiness. The Mallampati Scoring System is an assessment of the anatomy of the oral cavity to predict the ease of intubation and is believed to interfere with airway patency while asleep. The relationship between the Mallampati Score System, Berlin Questionnaire, and Epworth Sleepiness Scale were analyzed. Research Question:What relationship exists between the Mallampati Scoring System, the Berlin Questionnaire, and the Epworth Sleepiness Scale? Methodology: Participants of the research (N=77) were required to complete both the Berlin Questionnaire and the Epworth Sleepiness Scale as truthfully as possible. After each was completed, the researcher assessed the participants Mallampati Score by examining the oral cavity. Results: The multiple regression analysis was conducted to determine the accuracy of the Berlin Questionnaire score and Mallampati score to predict the Epworth Sleepiness score. In addition a linear regression analysis was conducted to determine if the independent variable Mallampati Score could predict the Berlin Questionnaire score. The model summary and the ANOVA summary indicate the Berlin Questionnaire score and the Mallampati score are weak predictors of the Epworth Sleepiness score (R2 =.017,R2adj =-.010,F(2,74)=.623, p>0.05). A review of the beta weights confirms that the Berlin and the Mallampati do not significantly contribute. (Table 1) The linear regression results indicate the Mallampati score is a weak and non-significant predictor of the Berlin Questionnaire score (R2 =.026,R2adj =.013,F(1,75)=2.022,p>0.05). Conclusion: Results of this pilot study reveal that the Mallampati Scoring System and the Berlin Questionnaire are not strong predictors of excessive daytime sleepiness as measured by the Epworth Sleepiness Scale results. In addition, the Mallampati score is not a strong predictor of the risk for sleep apnea as assessed by the Berlin Questionnaire. Sponsored Research - None
