BackgroundNon-invasive ventilation (NIV) is increasingly used to support very old (aged ≥85 years) patients with acute respiratory failure (ARF). This retrospective observational study evaluated the impact of NIV on the prognosis of very old patients who have been admitted to the intermediate care unit (IMC) of the Emergency Department of the University Hospital Policlinico-Vittorio Emanuele of Catania for ARF.MethodsAll patients admitted to the IMC between January and December 2015 who received NIV as the treatment for respiratory failure were included in this study. Outcomes of patients aged ≥85 years were compared with lower ages. The expected intrahospital mortality was calculated through the Simplified Acute Physiology Score (SAPS) II and compared with the observed mortality.ResultsThe mean age was 87.9±2.9 years; the M:F ratio was approximately 1:3. The average SAPS II was 50.1±13.7. The NIV failure rate was 21.7%. The mortality in the very old group was not statistically different from the younger group (20% vs 25.6%; d=5.6%; 95% CI -8% to 19%; p=0.404). The observed mortality was significantly lower than the expected mortality in both the group ≥85 (20.0% vs 43.4%, difference=23.4%; 95% CI 5.6% to 41.1%, p=0.006) and the younger group (25.6% vs 38.5%, difference=12.9%; 95% CI -0.03% to 25.8%, p=0.046). In both age groups, patients treated with NIV for chronic obstructive pulmonary disease had lower mortalities than those treated for other illnesses, although this was statistically significant only in the younger group.ConclusionIn very old patients, when used with correct indications, NIV was associated with mortality similar to younger patients. Patients receiving NIV had lower than expected mortality in all age groups.© Author(s) (or their employer(s)) 2019. No commercial re-use. See rights and permissions. Published by BMJ.
