Résumé
Objective:To explore the relative importance of palliative care knowledge, attitude towards palliative care and healthy work environment of emergency care nurses in predicting perceived self-competence in palliative care based on dominance analysis, and to provide empirical evidence for formulating the optimal training course to improve perceived self-competence in palliative care.Methods:Totally 415 emergency care nurses from 22 tertiary hospitals in Hubei province were conducted a cross-sectional survey to complete the general information questionnaire, the Palliative Care Nursing Self-Competence Scale, the Hospice Knowledge Quiz for Nurses, the Frommelt Attitudes Toward Care of the Dying Scale Form B, and the American Association of Critical Care Nurses Healthy Work Environment Assessment Tool from January to March 2021 using convenient sampling method. Dominance analysis was used for statistical analysis.Results:The total score of perceived self-competence in palliative care of 415 emergency care nurses was (225.48 ± 60.61) points, the total score of palliative care knowledge was (12.44 ± 3.83) points, the total score of palliative care attitude was (97.35 ± 9.07) points and the total score of healthy work environment was (72.00 ± 11.99) points. Perceived self-competence in palliative care was positively associated with palliative care knowledge ( r=0.181, P < 0.01), attitude towards palliative care ( r=0.232, P<0.01) and healthy work environment ( r=0.393, P<0.01). Dominance analysis revealed that the healthy work environment, palliative care attitude and palliative care knowledge accounted for 74.15%, 14.97% and 10.88% of the variance of perceived self-competence in palliative care, respectively. Conclusions:The largest degree of prediction for emergency care nurses′ perceived self-competence in palliative care is healthy work environment, attitude next and the third is knowledge. It suggests that promoting a healthy work environment is an important way to improve nurses′ perceived self-competence in palliative care, and improving knowledge level and cultivating positive attitudes also will be better.
