OR: odds ratio; CI: confidence interval; CHF: chronic heart failure; COPD: chronic obstructive pulmonary disease.

To limit the number of variables in the regression model due to the small sample size and since age and gender were not significant for any of the healthcare professionals, we did not include these two variables in the final regression model.

Belgium was chosen as the reference group, since this was the first category within variable country.

^a‘Country’ as a variable refers to the selection of integrated palliative care initiatives in that country, not directly to the whole country.
