P013 Continuous Positive Airways Pressure (CPAP) Adherence in Remote Patients using Telemedicine Model of Care

Abstract Background CPAP is an established first-line treatment for moderate-to-severe OSA. Adherence universally low and predicted by short-term adherence. Moderate-to-severe OSA strongly associated with adverse cardiovascular outcomes. Evidence of benefit limited to underpowered subgroups arbitrarily defined "good adherence". Covid-19 has generated widespread acceptance uptake telemedicine. This study aims determine if adherence affected when health service provided telemedicine rather than in-person. Methods Single-centre, retrospective, cohort patients identified between 1/6/21 30/6/22. Medical records were reviewed residential address, referral pathway (face-to-face or telemedicine), age, gender, BMI, ESS, AHI AI. Short-term was determined from downloads. Progress date 368 identified, 40% had 31.5% (64% remote, 36% local). Compared in-person, remote similar age (age ≥ 50, 64.9% vs 53.2%, p= 0.075) but more likely male (66.2% 50%, 0.014). ESS (9.7 ± 1.4 9.1 0.7, 0.38), BMI (36.1 2.5 33.5 1.3, 0.08), (27.5 7.5 21.7 3.4, 0.12) presence (48.6% 42.5%, 0.35) similar. Patient including local, face-to-face reviews analysed. data pending. Intended outcome impact Pilot programs (e.g. TeleSleep) are developing services designed provide accessible efficient care patients. $800 per patient, environmental transport savings can be anticipated.
