Telemonitored CPAP in OSA patient follow-up. Our evidence

Introduction and Objective: Treatment with CPAP should be monitored to ensure adequate control. AutoCPAP (APAP) is useful to do it. CPAP telemonitoring systems (TM) can transmit information about compliance and control. Our goal is to verify the accuracy between a TM system versus an APAP device, in terms of compliance and effectiveness. Methods: Prospective study of OSA patients in follow-up, treated with TM system (Airview-AutoSet-S10) and subjected to an evaluation with APAP (AutoSet-S9). The concordance between both systems (daily use, residual AHI-rAHI and leakage) was analyzed by dispersion measures, Bland-Altman, Intraclass Correlation Coefficient (ICC), ROC curves. Statistical significance (p Results: 476 patients were recruited: 79% males, mean age 60.6 years old. For both TM and APAP we found correlation for use, rAHI and 95th percentil leak (95PL) (figure 1). According to the ROC curves, compared to APAP TM showed capacity to analyze compliance, to recognize rAHI >5 and also to recognize 95PL >24 lpm (figure 2). Conclusions: TM is usefull to monitor the compliance and efficacy of CPAP therapy. TM advantages can be applied in OSA patients (comfort, cost-effectiveness).
