Patient reluctance to accept Do Not Resuscitate order: impact on clinical care.

BACKGROUND: A Do Not Resuscitate (DNR) order should only impede the performance of cardiopulmonary resuscitation in case of cardiac or respiratory arrest; it should not interfere with any other treatment decisions. AIMS: To study the impact of DNR order placement on daily clinical care of patients. METHODS: This was a retrospective cohort study of 72 patients in a tertiary care centre in Saudi Arabia. Daily clinical care measures were collected for 2 weeks prior and 2 weeks after DNR order placement and included vital signs, nursing care, comfort measures, documentation, visits by senior and junior physicians, and tests completed. RESULTS: Malignancy was the most common diagnostic category (43.1%). There was a significant reduction in vital signs documentation, tests completed, documentation, and visits by physicians after DNR orders, with no change in nursing care and comfort measures. No differences were seen for place of DNR order (intensive care unit vs medical ward), category of disease, or sex, but there were differences for documentation (more in females) and vital signs (more in males). More vital signs were documented and more tests were done in patients who survived compared to those who died. Regression analysis showed that the frequency of post-DNR order vital signs measurements and investigations done was not related to sex, age, diagnosis, time from admission to DNR order, or location of patients. Time to death was only related to sex and post-DNR order summary documentation. CONCLUSIONS: Placement of DNR orders significantly reduced vital signs measurements, investigations done, documentation and visits by physicians but not nursing care and comfort measures.
