Remarks of the reviewers and answers of the authors:
Could you please explain what a Belgian tertiary hospital is?We use the term 'tertiary' hospital as a synonym for a university hospital. This was adapted in the manuscript (in the abstract as well as in the method's section).Did the questionnaire you gave to the physicians also include questions why they decided to send the patients to the ICU or not?We agree that this would have been extremely valuable information. However, in order to have a maximum response rate, we used a very short questionnaire asking only objective data on the patient as well as on the DNR code and who participated in the decision to limit therapy.How was the decision made for a special DNR-Code? Was this decision mainly based on medical facts (prognosis underlying disease, comorbidity, functionality) or was this an overall decision with the participation of patient family, nurse and physician? Legal aspects in non-communicative patients -is there a legal representative who made the healthcare-decisions, or is that done by family members in Belgium?Legislation in Belgium demands that physicians inform and ask consent for every medical intervention/decision from the patient -or in case of incapacity from the surrogate decision-maker (this is in practice the nearest family).(this was added to the manuscript)The Order of Physicians in Belgium has added that it is also recommended to involve other members of the healthcare team (nurses!) in the DNR decision-making process.In this study, we see that 84% of competent patients were at least informed about the decision to limit therapy and that 100% of families of incompetent patients were informed. Only in 58%, nurses reported to be involved. (Table 1
