Abstract

Introduction: We observed improvements in 1-month CPAP adherence for new OSAS patients supported with telemetrically triggered supporting interventions in a pilot study.Methods: OSAS patients with AHI >5/h agreeing for long-term CPAP were randomized 1:1 to telemedicine (TM) or control group (non-TM). The primary endpoint was 1-month adherence. TM patients were monitored 3x per week for CPAP usage and mask leakage. Supportive phone calls were undertaken if there were 2 nights of usage <4h or excessive leakage.Results: 240 patients were randomized. 17 early absconders (11 TM, 6 non-TM) were excluded

Baseline characteristics of the study population

	With telemedicine	Without telemedicine	p-value
N	109	114
Gender (M/F)	83.5%	83.3%	1
Age (Years)	55.1 [44.1-63.9]	57.3 [47-65.3]	0.597
BMI (kg/m2)	30.8 [27.3-35.2]	31 [28-34.9]	0.614
AHI (events/h)	37 [23-68]	49.9 [27-67.5]	0.0891
ODI (events/h)	31 [18-58]	36 [21.5-59.5]	0.216
ESS (score points)	10 [6-13.5]	10 [8-13]	0.704

 

Among TM patients, 28 (26%) had no, 40 (37%) 1 or 2 and 41 (37%) 3 or more calls. Usage did not differ between groups

	With telemedicine	Without telemedicine	p-value
N	109	114
Daily usage	5.23 [3.66-6.45]	4.93 [3.69-6.56]	0.868
Proportion of nights with CPAP use	0.967 [0.8-1]	0.967 [0.8-1]	0.876
Prop. of nights with efficient CPAP use	0.767 [0.47-0.93]	0.733 [0.5-0.93]	0.906

 

A significant increase in usage was observed in the quartile of patients with low baseline Epworth sleepiness scale (ESS) scores.Conclusion: Targeted patient support to patients with CPAP usage problems in the first month did not result in significant increase in usage.
