AHI (apnea-hypopneas/hour) at 3 months and at 12 months will be compared to baseline. Succesfull treatment is defined as a reduction in AHI to < 5 events per hour at 3 months. Or either a 50% reduction in baseline AHI or a ≥ 10 decrease in AHI combined with improvement in ESS (≥ 2 points). The proportion of patients reaching succesfull treatment in both treatment arms will be compared using Fisher’s exact test. Relative risk of succesfull treatment between both treatment arms will be calculated and 95% Confidence interval of the risk difference.
Achtergrond van het onderzoek
Objective: To perform a randomized prospective trial comparing long-term outcomes in CPAP versus SPD (night balance) in central positional apnea patients.
Study design: A single-centre randomised prospective trial between CPAP and sleep position device treatment. Randomisation was stratified according to BMI and smoking. Physician and patients are not blinded to the treatment arms. Written patient informed consent is obtained. Diagnosis at baseline is by polysomnography. Eligible patients are randomized to either standard CPAP therapy or SPD treatment.
Epworth Sleepiness Scale (ESS) is measured at baseline and subsequently under treatment at 3 and 12 months. Polysomnography for AHI measurement is repeated under treatment at 3 and 12 months.
Study population: All patients with central positional sleep apnoea, with an AHI ≥ 5 and ≤ 30, are included in the study. Central sleep apnoea is defined as: AHI ≥ 5 with 50% or more of events occurring without any respiratory effort. And associated with symptoms of either excessive sleepiness or disrupted sleep. Positional sleep apnoea is defined as having a supine AHI≥2x AHI non-supine with ≥10% and ≤ 90% supine sleep.
Intervention (if applicable): Patient informed consent is obtained. Participants are assigned to either sleep position device (Night-Balance, Night Balance b.v., The Hague, The Netherlands) or CPAP (standard of care arm).
