In mainland China, the signing rate of DNR orders is low, and the establishment of DNR orders is associated with demographics and comorbidity characteristics.
Purpose: Studies concerning do-not-resuscitate (DNR) orders in mainland China are rather scarce. We explored the prevalence and related factors of DNR orders among in-hospital cardiac arrest (IHCA) patients at a general tertiary hospital in mainland China. Materials and Methods: We identified all IHCA patients hospital-wide between July 2019 and September 2020. Data regarding DNR status were collected from medical records. We investigated the frequency of DNR orders and explored the determinant factors of DNR establishment using logistic regression. Results: A total of 1154 IHCA patients were included, 535 (46.4%) of whom established DNR orders. The following variables were independently associated with a higher DNR rate: female (OR 1.491; 95% CI 1.130-1.965), older age (OR 1.016; 95% CI 1.008-1.024), being a local resident (OR 1.790; 95% CI 1.344-2.383), pulmonary infection (OR 1.398; 95% CI 1052-1.859), respiratory insufficiency (OR 1.356; 95% CI 1.009-1.823), shock (OR 1.735; 95% CI 1.301-2.313), acute stroke (OR 1.821; 95% CI 1.235-2.686),neurological dysfunction (OR 1.527; 95% CI 1.149-2.028) and cancer (OR 3.316; 95% CI 2.461-4.468). Counterintuitively, patients with new-onset coronary artery disease (OR 0.592; 95% CI 0.419-0.837) were less likely to create DNR orders. Conclusion: In mainland China, the DNR order signing rate is low, and the establishment of a DNR order is associated with demographics and comorbidity characteristics. (C) 2021 Elsevier Inc.
