Comparison of the clinical frailty score (CFS) to the National Emergency Laparotomy Audit (NELA) risk calculator in all patients undergoing emergency laparotomy.

ABSTRACT:

Aim

There is evolving evidence that preoperative frailty predicts outcomes of older adults undergoing emergency laparotomy (EmLap). We assessed frailty scoring in an emergency surgical population that included patients of all ages and then compared this to an established perioperative prognostic score.

Method

Data from the prospective Emergency Laparoscopic and Laparotomy Scottish Audit (ELLSA; November 2017-October 2018) was used. All adults over 18 were included. Frailty was measured using 7-point clinical frailty score (CFS).

Outcome measures

30-day mortality, hospital length of stay (LOS), 30-day readmission. Areas under the receiver-operating characteristic (ROC) curves were calculated for CFS (1-7) and compared to the National Emergency Laparotomy Audit (NELA) score with Forest plots used to compare 30-day mortality across CFS and NELA categories.

Results

A total of 2246 patients (median age 65 years [IQR 51-75]; female 51%) underwent EmLap (60% for colorectal pathology). A total of 10.6% were frail preoperatively (≥CFS 5). As CFS increased so did 30-day mortality (2.1% CFS1 to 25.3% CFS6 and 7; ꭓ² 78.2, p < 0.001) and median LOS (10 days CFS1 to 20 days CFS6 and 7; p < 0.001). Readmission rates did not differ significantly across CFS. ROC (95% CI) for mortality was 0.71 (0.65-0.77) for CFS and 0.84 (0.78-0.89) for NELA. Addition of CFS to NELA did not increase ROC value.

Conclusion

This study supports the prognostic role of frailty in the emergency surgical setting, finding increasing frailty to be associated with increased mortality and longer LOS in adults of all ages. Although NELA performed better, CFS remained predictive and has the advantage of being calculated preoperatively to aid decision-making and treatment planning.

Project description:Past studies have highlighted variation in in-hospital mortality rates among hospitals performing emergency laparotomy for large bowel perforation. The aim of this study was to investigate whether failure to rescue (FTR) contributes to this variability. Patients aged 18 years or over requiring surgery for large bowel perforation between 2013 and 2016 were extracted from the National Emergency Laparotomy Audit (NELA) database. Information on complications were identified using linked Hospital Episode Statistics data and in-hospital deaths from the Office for National Statistics. The FTR rate was defined as the proportion of patients dying in hospital with a recorded complication, and was examined in hospitals grouped as having low, medium or high overall postoperative mortality. Overall, 6413 patients were included with 1029 (16.0 per cent) in-hospital deaths. Some 3533 patients (55.1 per cent) had at least one complication: 1023 surgical (16.0 per cent) and 3332 medical (52.0 per cent) complications. There were 22 in-hospital deaths following a surgical complication alone, 685 deaths following a medical complication alone, 150 deaths following both a surgical and medical complication, and 172 deaths with no recorded complication. The risk of in-hospital death was high among patients who suffered either type of complication (857 deaths in 3533 patients; FTR rate 24.3 per cent): 172 deaths followed a surgical complication (FTR-surgical rate 16.8 per cent) and 835 deaths followed a medical complication (FTR-medical rate of 25.1 per cent). After adjustment for patient characteristics and hospital factors, hospitals grouped as having low, medium or high overall postoperative mortality did not have different FTR rates (P = 0.770). Among patients having emergency laparotomy for large bowel perforation, efforts to reduce the risk of in-hospital death should focus on reducing avoidable complications. There was no evidence of variation in FTR rates across National Health Service hospitals in England.

Project description:ObjectivesThis study used national audit data to describe current management and outcomes of patients undergoing surgery for complications of peptic ulcer disease (PUD), including perforation and bleeding. It was also planned to explore factors associated with fatal outcome after surgery for perforated ulcers. These analyses were designed to provide a thorough understanding of current practice and identify potentially modifiable factors associated with outcome as targets for future quality improvement.DesignNational cohort study using National Emergency Laparotomy Audit (NELA) data.SettingEnglish and Welsh hospitals within the National Health Service.ParticipantsAdult patients admitted as an emergency with perforated or bleeding PUD between December 2013 and November 2015.InterventionsLaparotomy for bleeding or perforated peptic ulcer.Primary and secondary outcome measuresThe primary outcome was 60-day in-hospital mortality. Secondary outcomes included length of postoperative stay, readmission and reoperation rate.Results2444 and 382 procedures were performed for perforated and bleeding ulcers, respectively. In-hospital 60-day mortality rates were 287/2444 (11.7%, 95% CI 10.5% to 13.1%) for perforations, and 68/382 (17.8%, 95% CI 14.1% to 22.0%) for bleeding. Median (IQR) 2-year institutional volume was 12 (7-17) and 2 (1-3) for perforation and bleeding, respectively. In the exploratory analysis, age, American Society of Anesthesiology score and preoperative systolic blood pressure were associated with mortality, with no association with time from admission to operation, surgeon grade or operative approach.ConclusionsPatients undergoing surgery for complicated PUD face a high 60-day mortality risk. Exploratory analyses suggested fatal outcome was primarily associated with patient rather than provider care factors. Therefore, it may be challenging to reduce mortality rates further. NELA data provide important benchmarking for patient consent and has highlighted low institutional volume and high mortality rates after surgery for bleeding peptic ulcers as a target for future research and improvement.

Project description:BackgroundEmergency laparotomy (EmLAP) is one of the commonest emergency operations performed in the United Kingdom (approximately 30, 000 laparotomies annually). These potentially high-risk procedures can be life changing with frail patients and/ or older adults (≥ 65 years) having the poorest outcomes, including mortality. There is no gold standard of frailty assessment and no clinical chemical biomarkers existing in practice. Early detection of subclinical changes or deficits at the molecular level are essential in improving our understanding of the biology of frailty and ultimately improving patient outcomes. This study aims primarily to compare preoperative frailty markers, including a blood-based biomarker panel, in their ability to predict 30 and 90-day mortality post-EmLAP. The secondary aim is to analyse the influence of perioperative frailty on morbidity and quality of life post-EmLAP.MethodsA prospective single centred observational study will be conducted on 150 patients ≥ 40 years of age that undergo EmLAP. Patients will be included according to the established NELA (National Emergency Laparotomy Audit) criteria. The variables collected include demographics, co-morbidities, polypharmacy, place of residence, indication and type of surgery (as per NELA criteria) and prognostic NELA score. Frailty will be assessed using: a blood sample for ultra-high performance liquid chromatography mass spectrometry analysis; preoperative CT abdomen pelvis (sarcopenia) and Rockwood Clinical Frailty Scale (CFS). Patients will be followed up for 90 days. Variables collected include blood samples (at post operative day 1, 7, 30 and 90), place of residence on discharge, morbidity, mortality and quality of life (EQ-5D-5 L). The frailty markers will be compared between groups of frail (CFS ≥ 4) and non-frail using statistical methods such as regression model and adjusted for appropriate confounding factors.DiscussionThis study hypothesises that frailty level changes following EmLAP in frail and non- frail patients, irrespective of age. We propose that non- frail patients will have better survival rates and report better quality of life compared to the frail. By studying the changes in metabolites/ biomarkers in these patients and correlate them to frailty status pre-surgery, this highly novel approach will develop new knowledge of frailty and define a new area of clinical biomolecular research.Trial registrationClinicalTrials.gov: NCT05416047.

Project description:Importance:Objective preoperative risk assessment tools, such as the Modified Frailty Index (mFI), may inform patient and physician decision making when considering total laryngectomy. Estimation of outcomes may help to set realistic expectations about recovery and outcomes and facilitate optimal resource management. Objective:To evaluate the association between the mFI score as a measure of frailty and outcomes following total laryngectomy. Design, Setting, and Participants:Retrospective evaluation using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP), a risk- and case-mix-adjusted national quality assessment program. The ACS NSQIP database identified 595 patients who underwent total laryngectomy between 2006 and 2012. Patients were assessed for demographics and comorbidity and were stratified on the basis of calculated mFI score. Outcomes, including postoperative complications, length of hospitalization, and discharge destination, were evaluated as a function of increasing frailty using multivariable logistic regression and Cox proportional hazards regression models. Main Outcomes and Measures:Risk of postoperative complications, length of hospitalization, and discharge disposition. Results:After exclusion of patients who experienced significant deviation from standard care protocols and those with missing or incomplete data, 343 individuals were included in the analysis. Of these, 278 (81.0%) were men, and the mean age was 63 years (95% CI, 61.9-64.4 years). Increasing frailty resulted in a nonlinear but progressive rise in incidence of postoperative adverse events. Overall, 96 (28.0%) patients experienced a postoperative complication, and patients with an mFI score of 3 or higher were more likely to develop postoperative complications than were patients with an mFI score of 0 (50.0% vs 16.7%; OR, 3.83; 95% CI, 1.72- 8.51). Patients in the highest frailty group experienced a longer mean duration of hospitalization (14.2 vs 9.5 days; difference, 4.7; 95% CI, 1.3-8.1 days) and were more likely to require skilled care after discharge (33.3% vs 3.2%; difference, 30.1%; 95% CI, 7.4%-52.9%). Conclusions and Relevance:An mFI score of 3 or higher is associated with increased risk for postoperative complications, longer hospitalization, and need for postdischarge skilled care following total laryngectomy. The mFI provides a personalized risk assessment to better inform patients, physicians, and payers when planning a total laryngectomy.
