There is evidence from outside the UK to show that physicians’ religious beliefs influence their decision making at the end of life. This UK study explores the belief system of consultants, nurse key workers & specialist registrars & their attitudes to decisions which commonly must be taken when caring for individuals who are dying. Results showed that consultants’ religion & belief systems differed from those of nurses & the population they served. Consultants & nurses had statistically significant differences in their attitudes to common end of life decisions with consultants more likely to continue hydration & not withdraw treatment. Nurses were more sympathetic to the idea of PAS for unbearable suffering. This study shows the variability in belief system and attitudes to end of life decision making both within and between clinical groups. The personal belief system of consultants was not shown to affect their overall attitudes to withdrawing life-sustaining treatment or PAS.
