TY - JOUR T1 - Restarting CPAP Therapy for Sleep Apnea After a Previous Failure JF - Respiratory Care SP - 1541 LP - 1546 DO - 10.4187/respcare.07766 VL - 65 IS - 10 AU - Heidi Avellan-Hietanen AU - Paula Maasilta AU - Adel Bachour Y1 - 2020/10/01 UR - http://rc.rcjournal.com/content/65/10/1541.abstract N2 - BACKGROUND: About one third of patients fail their first CPAP trial due to several factors. Despite its clinical importance, data on the success of CPAP re-initiation are scarce.METHODS: Of the 6,231 patients referred to our sleep unit for sleep apnea, we included 224 subjects referred for re-initiation of CPAP therapy (re-CPAP). The control group consisted of 228 CPAP-naïve subjects referred for CPAP initiation. Data on subject characteristics, sleep study, and CPAP outcome were collected.RESULTS: The re-CPAP group had more severe apnea than the control group. After at least 1 y of CPAP therapy, 52% of the re-CPAP group stayed on therapy; this was significantly lower than the 67% adherence for the control group (P = .001). No gender difference was observed in the control group (P = .12), whereas women in the re-CPAP group remained on therapy significantly less than men (P = .002).CONCLUSIONS: The percentage of subjects who stayed on CPAP therapy after 1 y was significantly reduced when CPAP was re-initiated compared to the control group. CPAP acceptance after re-initiation was higher among men than women. Further studies are necessary to explain this gender difference. ER -
