STUDY OBJECTIVES: To evaluate patient ratings of the acceptability of a peer buddy system (PBS). To promote continuous positive airway pressure (CPAP) therapy adherence in patients with obstructive sleep apnea (OSA). To obtain preliminary data on the effectiveness of PBS on sleep-specific health-related quality of life and CPAP adherence.
DESIGN: Prospective, randomized, and controlled study.
SETTING: Academic Center.
PARTICIPANTS: Thirty-nine patients with OSA and 13 patients with OSA who were experienced CPAP users.
INTERVENTIONS: Recently diagnosed patients with OSA were randomly assigned to either the PBS to promote CPAP adherence (intervention group) or usual care (control group).
MEASUREMENTS: Patient satisfaction, Functional Outcomes of Sleep Questionnaire (FOSQ), CPAP adherence, vigilance, self-efficacy, and patient activation were measured.
RESULTS: Ninety-one percent of the subjects rated the PBS as very satisfactory (68%) or satisfactory (23%). During the 90 days of therapy, weekly CPAP adherence was greater in the intervention than the usual care group (MANOVA; F = 2.29; p = 0.04). Patient satisfaction was positively correlated with CPAP adherence (R(2) = 0.14; p = 0.02). We did not find any group differences for FOSQ, vigilance, self-efficacy, or patient activation in this pilot study.
CONCLUSION: Our pilot study suggests that the PBS intervention is feasible and received high patient satisfaction ratings. CPAP adherence may be improved by peer-driven intervention, but a larger, adequately powered study is needed.
