  "abstract": "Introduction There is evidence that CPAP telemonitoring improves CPAP adherence 1 and reduces clinical contacts.2 Previous data in a low-adherence cohort from our centre demonstrated that comfort interventions (masks, humidifiers) offered at clinic follow-up did not lead to improvement in long-term adherence.3 We hypothesised that identifying poor CPAP users and offering remote interventions prior to clinic follow-up may lead to more definitive clinic outcomes.Method Non-adherent CPAP users, defined as using CPAP for >4 hours on < 70% of nights, were identified using the Sefam telemonitoring platform. They were telephoned by a physiologist or physician associate and a checklist of common CPAP problems discussed. Simple interventions were arranged e.g. mask, humidifier, settings change, or face-to-face physiologist appointment. CPAP usage and clinic outcomes in consultant-led clinics were recorded. A definitive clinic outcome was one that ended this pathway: patient-initiated follow up (PIFU), discharge or physiologist-led CPAP review clinic.Results 90 patients were followed up in clinic, of whom 58 had answered and 32 had not answered the 4-week phone call. Of those who answered, 29.3% were offered a face-to-face physiologist appointment, 17.2% a humidifier and 15.5% a new mask.CPAP adherence at follow-up was similar between the answered and unanswered groups and there was minimal change in CPAP usage at 4-weeks post initiation compared to first clinic follow-up (table 1).There was a trend indicating that patients who answered the call were more likely to have a definitive clinic outcome compared to those who did not (46.6 vs 34.4%, p=0.26), suggesting that this intervention could save 7.8 consultant-led appointments per 100 non-adherent patients called.Discussion This intervention did not improve CPAP adherence. Results suggest that a 4-week intervention enabled more patients to have a definitive outcome at first follow-up, saving appointments in limited consultant-led clinics.References Labarca G, Schmidt A, Dreyse J, Jorquera J, Barbé F.
