“…If we consider the results obtained by participants in the current study according to their levels of experience and training palliative care, we find that both participants with experience and with training in palliative care got better results on the questionnaire. These results are similar to studies in which professionals with previous training or participating in training programs in the field of palliative care [ 31 , 44 , 45 , 48 ], and also those who work in environments such as long-stay centres, nursing homes, oncology units and services of palliative care [ 42 , 43 , 46 , 47 ] obtained the best results. Furthermore, in the studies developed in Ethiopia, Jordan, and Saudi Arabia the lack of training in palliative care is considered as one of the main factors that would explain the deficit of knowledge of nurses in this area [ 31 , 49 ].…”
