Abstract

Aim: We examined fifteen years trends (2001-2015) in the use of non-invasive ventilation (NIV), invasive mechanical ventilation (IMV) or both (NIV+IMV) among patients hospitalized for community acquired pneumonia (CAP). We also analyzed trends overtime and the influence of patient factors in the in-hospital mortality (IHM) after receiving NIV, IMV or NIV+IMV.

Methods: Observational retrospective epidemiological study. Our data source was the Spanish National Hospital Discharge Database.

Results: Over a total of 1,486,240 hospitalized patients with CAP, we identified 56,158 who had received ventilator support in Spain over the study period. Of them, 54.82% received NIV, 37.04% IMV and 8.14% both procedures. The use of NIV and NIV+IMV increased significantly (p<0.001) over time (from 0.91 to 12.84 per 100.000 inhabitant and from 0.23 to 1.19 per 100.000 inhabitants, respectively), while the IMV utilization decreased (from 3.55 to 2.79 per 100,000 inhabitants; p<0.001). Patients receiving NIV were the oldest and had the highest mean value in the Charlson comorbidity index (CCI) score and readmission rate. Patients who received only IMV had the highest IHM. Factors associated with IHM for all groups analyzed included age, comorbidities and readmission. IHM decreased significantly over time in patients with CAP who received NIV, IMV and NIV+IMV.

Conclusions: We found an increase in NIV use and a decline in IMV utilization in patients hospitalized for CAP over the study period. Patients receiving NIV were the oldest and had the highest CCI score and readmission rate. IHM decreased significantly over time in patients with CAP who received NIV, IMV and NIV+IMV.
