A Cross Sectional Observational Study To Compare Berlin Questionnaire Vs Stop Bang In Diagnosing Osa

Abstract

Introduction: OSA(obstructive sleep apnoea) which is characterized by repetitive episodes of upper airway obstruction, snoring, repeated airflow termination (apnoea), and hypoxemia during sleep. Even though multiple studies were previously done , which compared the scores under study their results varied among different population. So the present study was conducted to know the efficiency of the scoring systems among Indian population.

Aims and objectives: To assess the correlation of BERLIN and STOP BANG with AHI to predict their ability in diagnosing OSA.

Materials and methods: It was a cross sectional observational study conducted on 40 Patients. All patients detailed clinical history, demographic data including age, sex were collected. Anthropometric indices such as Height, weight, body mass index were collected in all patients. Presence of any co morbidities were noted. All patients filled both BERLIN and STOPBANG questionnaires. Then we performed  polysomnography using Type 3 sleep study. The results of sleep study were compared with both scores.

Results: AHI was compared with grades of BERLIN and STOP BANG. Both BERLIN and STOP BANG had P value <0.001 which was statistically significant.

Conclusion: As the OSA severity increases the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of STOP BANG increases, in turn indicating STOP BANG scoring is better for SEVERE forms of OSA, while BERLIN is better for milder forms.
