Abstract

Objective: The initiation of palliative care (PC) in the emergency department (ED) is effective in improving the quality of life for seriously ill patients. This study aimed to evaluate the prognostic value of the modified surprise question (mSQ), “Would you be surprised if this patient died in the next 30 days?” as a trigger for initiating PC in critically ill ED patients. Methods: We conducted a prospective cohort study over a 6-month period in an ED, during which 22 emergency residents answered the mSQ for critically ill ED patients (Korean Triage and Acuity Scale 1 or 2). The primary outcome was the accuracy of the positive mSQ (negative response to the mSQ) in predicting 30-day mortality, and logistic regression analysis was performed to identify the prognostic factors. Results: A total of 300 patients were enrolled, and the positive mSQ group included 118 (39.3%) patients. The 30-day mortality rate of the cohort was 10.0%. The sensitivity, specificity, positive predictive value, and negative predictive value of the positive mSQ were 83.3%, 65.6%, 21.2%, and 97.3%, respectively, with a c-statistic of 0.74 and a positive likelihood ratio of 2.42. In a multivariable analysis controlling for clinically relevant variables, the odds ratio for 30-day mortality of the positive mSQ was 4.76 (95% confidence interval, 1.61-14.09; P = .005). Conclusions: The mSQ may be valuable for identifying critically ill ED patients with an increased risk of 30-day mortality. Therefore, it may be utilized as a trigger for PC consultation in the ED.
