Personalized Feedback to Improve CPAP Adherence in Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is effectively treated with continuous positive airway pressure (CPAP). Low rates of CPAP adherence led to the development of a personalized feedback intervention requiring minimal provider burden. In a comparison of the intervention to standard information, group differences failed to reach significance. Explanations for the findings include low power, that machines were not provided, and an atypical sample. Effect sizes were medium to large at 2 weeks, suggesting that sufficiently powered studies may be warranted
