Proactive telemedicine monitoring of sleep apnea treatment improves adherence in people with stroke– a randomized controlled trial (HOPES study)

Abstract

ObjectiveObstructive sleep apnea (OSA) impacts stroke recovery and outcome negatively. Although its identification and treatment are part of the current stroke guidelines, standard management with positive airway pressure (PAP) therapy is not routinely performed and adherence rates are very low. The purpose of this study was to determine whether PAP adherence can be improved by a PAP training strategy during in-hospital rehabilitation combined with a telemedicine monitoring system after discharge. MethodsIn this study, we performed a controlled trial (RCT) on standard PAP treatment (SG) as compared with proactive telemonitored PAP treatment (TG). After three months and one year, PAP adherence (min of use per day) and clinical outcome variables were compared. ResultsIn 33 (47.1%) out of 70 patients diagnosed with therapy-relevant OSA [70% male, 62 (5) years, body mass index (BMI) 30 (4) kg/m2, Barthel Index 90 (20), NIHSS 3 (3)] in-hospital PAP titration was performed. Subsequently, they were randomized to SG or TG. Drop-out rates after three months and after one year were 12% and 30%, respectively, with no differences between the groups. After three months, telemonitored patients used the PAP device 76 min longer per night (SG: 299 (76), TG: 375 (86) minutes per night; p = 0.017), after one year there was no significant difference. ConclusionPeople with stroke and therapy-relevant OSA who accept PAP therapy should receive additional telemedicine monitoring at least for three months.
