Patient motivation ranked by caregivers at continuous positive airway pressure initiation is predictive of adherence and 1-year therapy termination rate.

Abstract

In patients diagnosed with obstructive sleep apnea (OSA), continuous positive airway pressure therapy (CPAP) is effective in reducing symptoms and improving quality of life. However, poor mid- to long-term adherence and high termination rates are a problem. We asked whether or notpatient motivation at CPAP initiation was associated with 15-day and 1-year CPAP adherence and termination rates. In this nationwide multicenter observational study, individual patient motivation for achieving CPAP adherence was subjectively evaluated at the time of CPAP set-up by the home-care provider's technician on a simple scale (low, average, good, very good). Then, adherence and CPAP termination rates were objectively monitored via the home-care provider's CPAP remote monitoring platform at 15 days and 1 year. A total of 10,450 adults withOSA initiating CPAP were included by 36 centers. CPAP adherence at day 15 was significantly different between the low and the very good motivation groups: 5.4 [3.2; 6.9] hours and 6.0 [4.2; 7.3] hours per night respectively. In the 72.0% of patients using CPAP at 1 year, CPAP adherence was 5.2 [3.1; 6.7] and 5.5 [4.0; 7.0] hours per night in the groups with low and very good motivation respectively. Therapy termination rates at 1 year were 14.6% in the low motivation group and 8.0% in the very good motivation group. Our study suggests that motivation of patients withOSA estimated by caregivers at CPAP initiation using a simple four-item ranking is associated with CPAP adherence and primary therapy termination rates during the first year of treatment.
