To describe the development and assess the usability of a patient decision aid (PtDA) prototype designed for newly diagnosed, treatment-naïve, obstructive sleep apnea (OSA) patients.A web-based PtDA was developed which focuses on two first-line treatment options: continuous positive airway pressure (CPAP) and mandibular advancement splints (MAS). Development was guided by the International Patient Decision Aid Standards (IPDAS). Usability was assessed in individuals at high risk for OSA based on the STOP-Bang questionnaire, the patient acceptance of decision aid, the System Usability Scale (SUS), and content analysis of open-ended user feedback.Eighty eligible participants completed the survey. The mean age was 54 years (SD = 8.9), 60 % of the sample was male, 78 % were university-educated, and 64 % were employed full-time. Participants took an average of 13.7 min (SD = 9.6) to complete the PtDA, with 39 participants choosing CPAP, 25 choosing MAS, and 16 choosing no treatment. The mean SUS score was 78.22 (SD = 15.13). The majority of individuals thought the PtDA was useful in making a decision (n = 77, 96 %) and would recommend it to others (n = 77, 96 %), while a third (n = 26, 33 %) thought it was slanted towards CPAP.The SUS indicated that the PtDA was acceptable and useful for participants. And useful for participants. User feedback has been used to improve the prototype, which will now undergo further testing in patients at the Vancouver Sleep Disorders Clinic.
