Attitudes and knowledge about obstructive sleep apnea among Latin American primary care physicians

Abstract

Objectives: We aimed to evaluate Latin American primary care physicians' knowledge and attitudes about obstructive sleep apnea (OSA) using a Spanish-language version of the OSA Knowledge and Attitudes (OSAKA) questionnaire and to evaluate its psychometric properties.

Methods: We used a cross-sectional survey of general practice physicians in Ecuador, Peru, and Venezuela who completed the Spanish-language version OSAKA questionnaire.

Results: Of 684 primary care physicians surveyed, 367 (65%) responded (mean age, 45 years; range, 21-75 years). Mean total knowledge (proportion of 18 items correctly answered) was 60% (range, 0-100%). Less than half of physicians correctly answered the questions about the association between OSA and hypertension. We found no significant differences in overall knowledge in gender or time since graduation (< or =5 years vs. >5 years). Although 73.5% of the physicians felt confident in identifying patients at risk for OSA, only 35.4% felt confident in managing those patients and 22.1% felt confident in managing patients with continuous positive airway pressure (CPAP) therapy. The Spanish-language version of the OSAKA questionnaire had comparable psychometric properties to the English-language version.

Conclusions: This Spanish-language version of the OSAKA yielded considerable variance in Spanish-speaking physicians' knowledge about OSA and confidence in identifying and managing patients with OSA. Focused OSA education for Latin American general physicians is needed.
