Abstract Background: Rapid Response Teams (RRT) are a critical care resource that reviews deteriorating patients within the hospital. Whilst contemporary literature has focused on outcomes of RRTs, little is known about the detailed perioperative course and characteristics of patients who require RRT activation after major hip surgery. We aimed to describe demographic, preoperative, surgical, anesthetic and postoperative characteristics of patients who required RRT activation after major hip surgery. We also sought to assess if these characteristics affected mortality during the index hospital admission. Methods: We reviewed a RRT database of adult patients undergoing orthopedic surgery at a university teaching hospital. We then retrospectively reviewed the medical records to extract a priori defined patient, preoperative, surgical, anesthetic and postoperative data of major hip surgery admissions between September 2014 and December 2017. Patients who survived the index hospital stay were compared to those who died.Results: Overall, 187 patients had a postoperative RRT activations. Mean (SD) age was 82.1 (11.6) years; 125 (67%) were female and most patients had at least one significant comorbidity: mean (SD) Charlson Comorbidity Index (CCI) of 5.6 (2.1). The majority of patients (68%) were frail, ASA class 3 or greater (91%) and underwent non-elective surgery (88%). Median (IQR) time from surgery to RRT activation was 29.4 hours (11.3:75.0), and 25 (13%) patients had unplanned admissions to ICU/HDU. Compared to patients who survived RRT activation, those who died displayed higher CCI [6.5 (1.8) vs. 5.5 (2.1); p=0.02], were more frail (80.1% vs. 56.5%; odds ratio 3.2; 95%CI: 1.2 to 8.1; p=0.03) and received less intraoperative opioids [median (IQR) intravenous morphine equi-analgesia 5.8 (0.1:8.2) mg vs. 11.7 (3.7:19.0) mg; p=0.03]. They were also more likely to receive an urgent medical review prior to RRT activation (62% vs 40%; odds ratio 2.4; 95%CI: 1.1 to 5.6; p=0.05).Conclusions: Death after RRT activation occurred in 1 out of 7 patients undergoing major hip surgery. Common patient characteristics included advanced age (>82 years), frailty, high CCI and emergency surgery. Further studies investigating perioperative surveillance teams in the identification of the high-risk patients before surgery, and deteriorating patients after major hip surgery, are warranted.

We aimed to describe demographic, preoperative, surgical, anesthetic, and postoperative characteristics of patients who required RRT activation after major hip surgery. We also sought to assess whether these characteristics where associated with mortality during the index hospital admission.Methods: We reviewed an RRT database of adult patients undergoing orthopedic surgery at a university teaching hospital. We then retrospectively reviewed the medical records to extract a priori–defined patient, preoperative, surgical, anesthetic, and postoperative data of major hip surgery admissions between September 2014 and December 2017. Patients who survived the index hospital stay were compared to those who died.Results: Overall, 187 patients had postoperative RRT activations. Median (interquartile range) age was 84.0 (78-90) years; 125 (67%) were female, and most patients had at least one significant comorbidity, median Charlson Comorbidity Index (CCI) 5.0 (4.0-7.0). The majority of patients were frail (68%), American Society of Anesthesiologists physical status Class 3 or greater (91%), and underwent nonelective surgery (88%). Median (interquartile range) time from surgery to RRT activation was 29.4 (11.3–75.0) hours, and 25 (13%) patients had unplanned admissions to intensive care or high dependency units. Compared to patients who survived RRT activation, those who died displayed 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).

Day Of Surgery Admission

A Perioperative Service has recently been introduced at Liverpool Hospital, a 460-bed university teaching hospital. This provides a co-ordinated system for managing all elective surgical patients from the time an admission is booked until hospital discharge. This paper describes the patient assessment, structure and staff requirements, benefits of and problems encountered with this service. The patient's preoperative preparation occurs before hospital admission. Where possible, patients are admitted on the day of procedure, either as a day-only patient, or a day-of-surgery patient. Patients are initially admitted to a specifically designed Perioperative Unit, adjacent to the Operating Theatre Suite. Patients do not enter the surgical wards until after their operation. Planning of the hospital discharge process commences at the time of booking for operation. Introduction of the Perioperative Service was staged process commencing in mid-1992. The hospital admits approximately 6,400 elective surgery cases each year. From July 1992 to December 1994, day-only patients were approximately 45% of these cases. Day-of-surgery admission patients increased from 6% to 35% of all cases over the same period. Appproximately 22% of elective surgical cases were seen in the Perioperative Clinic. As the Perioerative Service became fully operational, the average length of stay for elective surgical procedures fell. There has been a reduction in the areas of cancellations due to unavailablity of beds, inappropriate preparation of patients, and non-attendance of patients for booked procedures. Patient acceptance is high. The existence of a perioperative system facilitates the planning and management of elective surgery with maximum quality and efficiency.

Purpose of the studyDespite mature rapid response systems (RRS) for clinical deterioration, individuals activating RRS have poor outcomes, with up to one in four dying in hospital. We aimed to derive and validate a risk prediction tool for estimating risk of 28-day mortality among hospitalised patients following rapid response team (RRT) activation.Study designAnalysis of prospectively collected data on 1151 consecutive RRT activations involving 800 inpatients at a tertiary adult hospital. Patient characteristics, RRT triggers and actions, and mortality were ascertained from medical records and death registries. A multivariable risk prediction regression model, derived from 600 randomly selected patients, was validated in the remaining 200 patients. Main outcome was accuracy of weighted risk score (measured by area under receiver operator curve (AUC)) and performance characteristics for various cut-off scores.ResultsAt 28 days, 150 (18.8%) patients had died. Increasing age, emergency admission, chronic liver disease, chronic kidney disease, malignancy, after-hours RRT activation, increasing National Early Warning Score, major/intense RRT intervention and multiple RRT activations were predictors of mortality. The risk score (0–105) in derivation and validation cohorts had AUCs 0.86 (95% CI 0.82 to 0.89) and 0.82 (95% CI 0.75 to 0.90), respectively. In the validation cohort, cut-off score of 32.5 or higher maximised sensitivity: 81.6% (95% CI 68.4% to 92.1%), specificity: 56.2% (95% CI 49.4% to 63.6%), positive likelihood ratio (LR): 1.9 (95% CI 1.5 to 2.3) and negative LR: 0.3 (95% CI 0.2 to 0.6).ConclusionA validated risk score predicted risk of post-RRT death with more than 80% accuracy, helping to identify patients for whom targeted rescue care may improve survival.

Coagulation Inhibitors

SummaryExtrinsic coagulation pathway inhibitor may be an important regulator of haemostasis to prevent thrombosis after tissue damage. The functional activity of this inhibitor was determined using a chromogenic substrate assay, and compared to the activities of anti thrombin, heparin cofactor II and protein C during the perioperative period of elective hip replacement (n = 28), cholecystectomy (n = 11), and vascular surgery (n = 5). Peroperatively, all the inhibitors decreased rather similarly and to the same degree as the decrease in albumin concentration. The decreases during hip surgery were about 2-fold the decreases observed during cholecystectomy. A significant peroperative increase in extrinsic pathway inhibitor activity was observed in vascular surgery, probably due to a bolus injection of heparin. Antithrombin, heparin cofactor II and protein C levels normalized on days 3-5 postoperatively in all three patient groups. Sustained low levels of extrinsic pathway inhibitor were observed on postoperative days 1 to 7 in hip surgery patients. Apparently, extrinsic pathway inhibitor is not an acute phase reactant. In uncomplicated surgery, the decreases of the coagulation inhibitor levels are mainly due to hemodilution.
