Clinical deterioration requiring rapid response team (RRT) review is associated with increased morbidity amongst hospitalised patients. The frequency of and association with RRT calls in patients undergoing major gastrointestinal surgery is unknown. Understanding the epidemiology of RRT calls might identify areas for quality improvement in this cohort. The objective of this study is to identify perioperative risks and outcome associations with RRT review following major gastrointestinal surgery. We conducted a retrospective cohort study using electronic databases at a large Australian university hospital. We included adult patients admitted for major gastrointestinal surgery between 1 January 2015 and 31 March 2018. Of 7158 patients, 514 (7.4%) required RRT activation postoperatively. After adjustment, variables associated with RRT activation included the following: hemiplegia/paraplegia (odds ratio [OR]: 8.0, 95% confidence interval [CI]: 2.3 to 27.8, p = 0.001), heart failure (OR: 6.9, 95% CI: 3.3 to 14.6, p < 0.001), peripheral vascular disease (OR: 5.3, 95% CI: 2.7 to 10.4, p < 0.001), peptic ulcer disease (OR: 4.2, 95% CI: 2.2 to 8.0, p < 0.001), chronic obstructive pulmonary disease (OR: 4.0, 95% CI: 2.2 to 7.2, p < 0.001), and emergency admission status (OR: 2.6, 95% CI: 2.1 to 3.3, p < 0.001). Following the index operation, 46% of first RRT activations occurred within 24 h of surgery and 61% had occurred within 48 h. The most common triggers for RRT activation were tachycardia, hypotension, and tachypnoea. Postoperative RRT activation was associated with in-hospital mortality (OR: 6.7, 95% CI: 3.8 to 11.8, p < 0.001), critical care admission (incidence rate ratio: 8.18, 95% CI: 5.23 to 12.77, p < 0.001), and longer median length of hospital stay (12 days vs. 2 days, p < 0.001) compared to no RRT activation. After major gastrointestinal surgery, one in 14 patients had an RRT activation, almost half within 24 h of surgery. Such activation was independently associated with increased morbidity and mortality. Identified associations may guide more pre-emptive management for those at an increased risk of RRT activation. |
