PurposeDo-not-resuscitate (DNR) orders are an important part of end-of-life care (EOL) for patients with incurable advanced lung cancer. The aim of this study was to investigate the clinical factors related to the acceptance of DNR orders by Chinese patients.MethodsThis study was a retrospective analysis involving patients with advanced-stage (IIIB or IV) lung cancer who died in hospital at our center from August 2004 through August 2014. The patients' clinical characteristics and DNR forms were reviewed.ResultsOf the 348 patients enrolled, 260 (74.7 %) provided DNR orders signed only by surrogates. The signing rate of DNR orders increased annually. The median interval from signing a DNR order to death was 1 day (range, 0-72 days). Patients with poor performance status (PS) (≥2) 1 week prior to death (OR, 3.395; 95 % CI, 1.536-7.502, P = 0.003) and relatively longer overall survival (OS) (>3 months) (OR, 2.464; 95 % CI, 1.566-4.472, P < 0.001) were more likely to sign DNR orders. CPR was performed on 10.3 % (27/260) of patients with DNR orders, and was withheld in 22.7 % (20/88) of patients without DNR orders.ConclusionsThe DNR order-signing rate has been increasing annually among terminal patients with lung cancer in China. DNR orders, all of which were signed by surrogates, were more likely to be accepted by patients with slowly deteriorating disease and longer OS. More effort should be taken to help patients and medical professionals establish a sensible understanding of EOL care, including DNR orders, at earlier points during the disease course.
