Model 1: independent predictors for a decision for (or against) noninvasive ventilation (NIV)
| OR for NIV (95% CI) | p-value | |
| Department | ||
| Geriatric or palliative care | Reference | |
| Intensive care unit | 14.9 (1.87–118.8) | 0.011 |
| Pulmonology or internal medicine | 9.4 (1.14–78.42) | 0.038 |
| Physician recommends living will# | 0.57 (0.34–0.97) | 0.038 |
| Age of the physician (per year) | 0.96 (0.92–1.00) | 0.052 |
Odds ratios were obtained by multivariable logistic regression. OR >1 shows a higher probability for NIV. #: physicians with a positive answer to: “Do you advise patients with a foreseeably severe disease progression and/or limited life expectancy to draw up a living will?”.
