Introduction: TM seems to be an ideal tool to improve quality of care of the growing number of HNIV patients. However, the organization of such care as well as clinical outcomes are unknown. Methods: Multicenter, observational, prospective study. Two groups of patients were eligible for the study: 1. ventilated for more than 6 months and 2. starting HNIV. Trained staff analyzed ventilation quality alerts daily, excluding weekends, and intervened according to a formal protocol. Alerts' thresholds were set individually for each patient. Patients were clinically assessed before TM initiation and after 3 months by arterial blood gas analysis, overnight pulse oximetry, questionnaires SRI, S3-NIV and CAT. Results: Between October 2022 and August 2023, a 3-month follow-up was completed in 52 patients (38 in group 1 and 14 (30%) in group 2; mean age 66 years old (range 28-92): 27 (52%) patients with COPD, 14 (27%) with restrictive disorders, 7 (13%) obesity hypoventilation syndrome, 4 (8%) neuromuscular disease. In the 2nd and 3rd month of TM, mean ventilation time increased in relation to the period before TM by 49 and 37 minutes, respectively (pConclusions: Preliminary results of the study suggest that TM may improve the quality of HNIV and physiological parametres of gas exchange.
