Rapid response team activation after major hip surgery: A case series.

Abstract

IntroductionWe describe the demographic, preoperative, surgical, anesthetic, and postoperative characteristics of patients who required a rapid response team (RRT) activation after major hip surgery. We determined the characteristics and outcomes of patients that require RRTs after major hip surgery, and their associations with mortality.Presentation of casesWe retrospectively reviewed adult patients undergoing major hip surgery in a university teaching hospital. We included patients who had an RRT or “code blue” activation post-surgery and within the index hospital admission. We extracted patient, surgical, anesthetic, and postoperative variables. We explored differences between patients who survived their index hospital stay and those who died.Discussion187 (9%) patients had a postoperative RRT activation. The median age was 84.0 (78–90) years; 125 (67%) were female, and most patients had significant comorbidities. The median Charlson Comorbidity Index (CCI) was 5.0 (4.0–7.0). Patients were frail (68%), ASA physical status ≥Class 3 (91%) and underwent emergency surgery (88%). Death after RRT activation occurred in 1 in 7 patients. Compared to patients who survived RRT activation, those who died had a higher mean CCI (6.5 [1.8] vs. 5.5 [2.1], P = 0.02), were more frail (80.1% vs. 56.5%, OR = 3.2, 95% CI: 1.2,8.1; P = 0.03), and received less intraoperative opioids (intravenous morphine equi-analgesia: median = 5.8 (0.1–8.20 vs. 11.7 (3.7–19.0) mg, P = 0.03).ConclusionMortality after RRT activation is associated with non-modifiable patients factors rather than surgical or anesthesia factors. Our findings provide opportunities for the implementation of strategies aimed at improving postoperative outcomes.
