Impact of a shift in treatment funding on a multidisciplinary sleep clinic: a cohort study.

Multidisciplinary Sleep Clinics for sleep apnea have long existed, bringing together neurologists, sleep specialists, dentists, orthodontists and surgeons. In Belgium, a shift in funding for obstructive sleep apnea treatment was implemented from January 1st, 2017. Funding was allowed for moderate to severe obstructive sleep apnea and the rules shifted for treatments delivery and monitoring by authorised medical opinion. We aimed to assess whether a shift in treatment funding was associated with a change in the multidisciplinary sleep practice. Sample consisted of all patients discussed in the sleep multidisciplinary team meetings of the University Hospital of Liege from January 2016 to December 2018. Interrupted times series, Mann-Whitney U tests and descriptive statistics were produced. There were no differences in patients age, male sex preponderance, body mass index, clinical presentation and level of obstruction. Baseline obstructive sleep apnea severity was significantly lower (mean apnea-hypopnea index and mean oxygen desaturation index lowered with p = 0.0189 and p = 0.0466, respectively) after the funding rules changed. Oral appliance and ENT surgery were more often offered after the shift in funding. The key changes of the new funding rules for obstructive sleep apnea were reflected in the patient selection and management by sleep multidisciplinary team meeting. Funding terms could influence the care we give, not only in treatment options, but also in patients selection.
