Background and objectives Treatment effectiveness, in terms of health benefits, is a composite of efficacy and adherence. Oral appliance (OA) usage is mainly based on self-reports, but nowadays, objective adherence monitoring for OAs is available. This study investigated the objective OA adherence and its determinants in obstructive sleep apnoea (OSA) patients. Materials and methods There were 29 subjects who were treated with OA; mean [SD] age 51.4 [11.1]; mean apnoea–hypopnoea index (AHI) [SD] 19.5 [10.0]. Anthropometric and sociodemographic parameters, AHI, daytime sleepiness, snoring, and adverse effects of OA as potential determinants were evaluated. Patients were classified as regular users if they wore OA at least 4 hours nightly 5–7 nights a week. Statistical analyses included the chi-square test, t -test, Mann–Whitney U -test, and linear regression analyses. Results At the 3-month follow-up, 68% of subjects were regular users and at 12-month follow-up, 64%. AHI, sociodemographic parameters, or adverse effects were not associated with OA adherence. Snoring seemed to improve weakly adherence, whereas mandibular retrusion reduced the weekly use, and smoking the nightly use of OAs. Limitations The follow-up time was short, and there were a relatively small number of patients with obtainable adherence data, therefore it is difficult to establish if OA therapy alone is a successful long-term treatment option for OSA patients. Conclusions/implications Adherence to OA therapy is mainly the outcome of patients' subjective comfort in everyday life through eliminating social disturbance of snoring. To best meet a subject's individual treatment need and to prevent suboptimal use of OA, a patient-tailored therapy including digital wear-time documentation is recommended. [ABSTRACT FROM AUTHOR] |
