AbstractTo be able to distinguish end-stage palliative sedation from euthanasia without having to refer to intentions that are difficult to verify, physicians must be able to manage palliative sedation appropriately (i.e., see that death is not hastened as a result of disproportionate medication). In the present study, we assessed whether or not this requirement is met in the Netherlands. We sent a retrospective questionnaire to 1,464 medical specialists, general practitioners, and nursing home physicians in the Netherlands. Furthermore, we held two sets of 20 and 22 semi-structured in-depth interviews with general practitioners, internists, lung specialists, and nursing home physicians. Although most guidelines discourage the administration of opioids alone for purposes of palliative sedation, opioids alone were administered for 22% of all the patients reported upon. Those physicians who were more experienced, general practitioners, and physicians who had consulted a palliative care expert administered only opioids significantly less often than the other physicians. The interviewees reported difficulties in assessing the appropriateness of medication, feeling uncertain about the pharmacokinetics of drugs used in moribund patients. Given that no more than 2% of the respondents perceived palliative sedation to be used as a form of euthanasia and that the use of opioids alone was not associated with shorter survival rates, the inappropriate use of opioids can only be attributed to a lack of knowledge or skill and/or a tradition of alleviating refractory dyspnoea with the use of opioids and not as an intentional means of hastening death.
