Background And Objective: Non-invasive ventilation (NIV) improves clinical outcomes in hypercapnic acute exacerbations of COPD (AECOPD), but the optimal model of care remains unknown.
Methods: We conducted a prospective observational non-inferiority study comparing three models of NIV care: general ward (Ward) (1:4 nurse to patient ratio, thrice weekly consultant ward round), a high dependency unit (HDU) (1:2 ratio, twice daily ward round) and an intensive care unit (ICU) (1:1 ratio, twice daily ward round) model in three similar teaching tertiary hospitals. Changes in arterial blood gases (ABG) and clinical outcomes were compared and corrected for differences in AECOPD severity (Blood urea > 9 mmol/L, Altered mental status (Glasgow coma scale (GCS) < 14), Pulse > 109 bpm, age > 65 (BAP-65)) and co-morbidities.
