PURPOSE: Obstructive sleep apnea (OSA) is a common, serious condition. Continuous positive airway pressure (CPAP) is the therapy of choice. Adherence remains problematic. Mask choice may be a modifiable risk factor for non-adherence. To our knowledge, no studies to compare a traditional nasal mask(TM) to a cloth nasal mask (CM) have been done. This pilot study was undertaken to compare usage and 90 day adherence rates.

METHODS: A single center, prospective, study to compare CM (SleepWeaver, Circadiance, Export PA) to a TM (Comfort Gel Nasal Mask, Phillips-Respironics, Andover, MA) in patients newly diagnosed with OSA . Ethics approval was obtained. Informed consent was obtained from all subjects. Subjects were allocated mask type based on odd or even day at the time of informed consent. Subjects to remain on therapy for 90 days. Subjects chose their own DME and routine care given, no specific requirements for CPAP type. Data were downloaded using the individual CPAP manufacturer's software.

RESULTS: 50 subjects were enrolled, 20 subjects completed the study (11 female), 12 subjects received the TM; 7/12 were using the TM at 90 days (58%), 8 subjects received the CM. 7/8 were using the CM at 90 days (87.5%). Downloaded objective compliance data on subjects who completed their 90 days demonstrated mean minutes of use per night were higher in the CM group 386.1 (Range 279-484 Min) compared to 278.5 (Range 92-402 Min) evidencing a mean increase of 107 minutes of CPAP usage.

CONCLUSIONS: The use of a CM type of patient interface for OSA therapy may improve initial and 90 day adherence (85 vs 57%) to therapy and increase minutes of use (386.1 vs. 278.5 min). Data support that an increase in daily use of CPAP provides improvement in health outcomes. Limitations include: small sample size, odd/even day allocation of mask distribution, the use of one type of TM and various CPAP’s. However, the standard of care in this study is similar to most care paradigms (i.e. a variety of CPAP machines are routinely prescribed) thus we believe that these results can be generalizable to this population. A future study with larger sample sizes will be required to provide additional evidence regarding the selection of CM as a first line interface for patients with OSA.

CLINICAL IMPLICATIONS: Mask type can have an impact on short and 90 day adherence in patients on CPAP therapy. Consideration of non - traditional masks may provide an alternative for some patients as a first line therapy.
