Objektiv måling sammenlignet med partners oppfatning av etterlevelse ved bruk av søvnapnéskinne.

Forskere fra Universitetet i Bergen, Haukeland universitetssykehus, Nasjonal kompetansetjeneste for søvnsykdommer og Høgskulen på Vestlandet har i denne studien undersøkt etterlevelse ved bruk av søvnapnéskinne hos pasienter med obstruktiv søvnapné (OSA) og undersøkt hvordan partner påvirket etterlevelse av bruk av apnéskinne. Videre undersøkte de om dette samsvarte med objektiv måling av apnéskinnebruken. 77 pasienter med mild, moderat eller alvorlig OSA deltok i studien (32,5% kvinner). Forskerne konkluderer med at partners oppfatning av apnéskinnebehandling har en positiv innvirkning på etterlevelse, og at dette kan bedre pasientens etterlevelse av behandlingen.

The aims of the present prospective clinical study were to determine objective, sensor-measured adherence to a mandibular advancement device (MAD) in patients with obstructive sleep apnea (OSA) and to identify partner-specific adherence-related factors. A total of 77 eligible participants with mild, moderate, or severe OSA and who were non-adherent to continuous positive airway pressure (mean age 56.2 years) participated in the study (32.5% women). The mean (range) observation time between MAD delivery and final follow-up was 8.3 (3.4-16.5) months. The mean apnea-hypopnea index (AHI) was 26.6 events/hr at baseline and 12.5 events/hr at the 8-month follow-up (both p < 0.001). The mean sensor-measured adherence at the 8-month follow-up was 60.1% for ≥4 hr/night of appliance use for ≥5 days/week. Average usage was 6.4 hr/night, when worn. The mean reduction in the AHI was significantly greater in the "good adherence" (Δ 17.4) than the "poor adherence" group (Δ11.0; p < 0.05). From the partner's perspective, the appliance had a positive effect on sharing a bedroom in the good- (55%) compared to the poor-adherence group (25%; p < 0.05) and on their relationship (51.7% versus 17.9%, respectively; p < 0.05). Regression analyses identified the partner's snoring and apneas to be the most significant factor predicting good adherence to MAD (odds ratio 4.4, 95% confidence interval 1.4-14.0). In conclusion, social factors, like partner perceptions, were positively associated with adherence, which indicate that partner's attitudes and support may be a resource that can be utilised to improve adherence in oral appliance treatment of OSA.
