Failure to Rescue as a Surgical Quality Indicator

An anesthesiology-led perioperative outreach service: experience from a Canadian centre and a focused narrative literature review

Approximately 320 million surgeries occur annually worldwide, increasingly performed on an ageing, comorbid population in whom postoperative complications contribute significantly to mortality. While anesthesiologists have led advances in perioperative care, the optimal structure of the provision of postoperative care has lacked discourse. In this article, we describe the implementation, structure, role, and benefits of an Anesthesiology Perioperative Outreach Service (APOS) at a Canadian tertiary hospital, providing proactive daily review and management of high-risk surgical patients. The APOS involves routine reviews and care on surgical wards, emphasizing collaboration among anesthesiology, internal medicine, surgery, and geriatric medicine teams, with a specific screening pathway to identify patients experiencing myocardial injury after noncardiac surgery. We discuss case vignettes to illustrate common examples of how the APOS enabled early detection and treatment escalation for deteriorating patients and provide a focused narrative literature review. The anesthesiology-led perioperative outreach model described herein could provide an implementable framework for institutions seeking to enhance their quality of postoperative care-particularly among complex, comorbid patients at risk of postoperative morbidity.

Root-cause analysis of mortality after pancreatic resection in a nationwide cohort

BACKGROUND

This study evaluates leading causes of in-hospital mortality after pancreatic resection nationwide to determine areas for improvement.

METHODS

This observational cohort study included all in-hospital mortality after pancreatic resection in the Netherlands (2014-2019). Each fatality was considered to be caused by local complications (i.e. directly related to surgery, located in surgical area) or systemic complications (e.g. cardiac or pulmonary). A blinded Expert Committee reviewed the postoperative course leading to death and identified potential quality improvement measures.

RESULTS

Out of 5345 patients undergoing pancreatic resection, 149 patients (2.8 %) died in-hospital. Local complications caused death in 126 patients (85 %) and systemic complications in 23 patients (15 %). Concerning local complications, the common leading causes of death were postoperative pancreatic fistula (n = 41) and thrombosis of vascular reconstructions (n = 23). Systemic cardiac (n = 8) and pulmonary (n = 7) complications caused death frequently. Potential areas for improvement were failure to rescue (n = 89; 60 %), prevention of complications (n = 34, 23 %) and patient selection (n = 14; 9 %).

CONCLUSION

Local complications often caused death after pancreatic resection, mainly pancreatic fistula and vascular reconstruction failure. Failure to rescue was considered the most important area for improvement to decrease in-hospital mortality further.

Events preceding death after high-risk surgery analyzed by Global Trigger Tool and reflective-thematic approach

BACKGROUND

Postoperative mortality might be influenced by postoperative care, vigilance, and competence to rescue. This study aims to describe the course of events preceding death in a high-risk surgical cohort.

METHODS

We analyzed hospital records of patients who died within 30 days after surgery in 4 high volume hospitals using (1) reflective narrative thematic approach to identify recurring themes reflecting issues with conduct of care and (2) Global Trigger Tool to describe incidence, timing, and types of adverse events (AEs) leading to harm.

RESULTS

Preoperative predicted median risk of death in the studied group was 9%/13% according to SORT/P-POSSUM, respectively. Nine recurring themes were identified. Prominent themes were "consensus concerning aim and/or risk with planned surgery," "level of (intraoperative) competence and monitoring," and in the postoperative period "level of care and vigilance" on signs of deterioration. We found a total of 303 AEs, with only three patients (5%) having no adverse events. Most common severity category was "I," that is "contributed to patient's death" (n = 110, 36% of all AEs). Of these, 60% were classified as preventable or probably preventable. The peak incidence of AEs was seen on the day of index surgery. Most common types of AEs were "failure of vital functions" (n = 79, 26%), followed by infections (n = 45, 15%).

CONCLUSIONS

A high predicted risk of death and a peak of adverse events on the day of index surgery were detected. Identified themes reflect lack of documented multi-professional consensus on how to handle prevalent perioperative risk, vigilance, and postoperative level of care.

Complication Timing, Failure to Rescue, and Readmission After Inpatient Pediatric Surgery

BACKGROUND

Complications are associated with postoperative mortality and readmission. However, the timing of complications relative to discharge and the extent to which timing is associated with failure to rescue (FTR) and readmission after pediatric surgery is unknown. Our goal was to describe the timing of complications relative to discharge after inpatient pediatric surgery and determine the association between complication timing, FTR, and unplanned readmission.

MATERIALS AND METHODS

National cohort study of patients within the NSQIP-Pediatric database who underwent inpatient surgery (2012-2019). Complications were categorized based on when they occurred relative to discharge: only pre-discharge, only post-discharge, both. The association between perioperative outcomes and the timing of postoperative complications was evaluated with multivariable hierarchical regression.

RESULTS

Among 378,551 patients, 30,213 (8.0%) had at least one postoperative complication. Relative to patients with pre-discharge complications, post-discharge complications were associated with significantly decreased odds of FTR (odds ratio 0.21, 95% confidence interval [0.15-0.28]) and significantly increased odds of readmission (odds ratio 19.37 [17.93-20.92]). Odds of FTR and readmission in patients with complications occurring both before and after discharge were similar to that of patients with only post-discharge complications.

CONCLUSIONS

FTR and readmission are associated with complications occurring at different times relative to discharge (FTR primarily pre-discharge; readmission primarily post-discharge). This suggests a 'one size fits all' approach to surgical quality improvement may not be effective and different approaches are needed to address different quality indicators.

Association between type of index complication and outcomes after noncardiac surgery

BACKGROUND

Failure to rescue, or the death of a patient after a surgical complication, largely occurs in patients who develop a cascade of postoperative complications. However, it is unclear whether there are specific types of index complications that are more strongly associated with failure to rescue, additional secondary complications, or other types of postoperative outcomes. This is a national cohort study of veterans who underwent noncardiac surgery at Veterans Affairs hospitals using data from the Veterans Affairs Surgical Quality Improvement Program (January 1, 2016 to September 30, 2021). Index complications were grouped into categories (cardiovascular, venous thromboembolism, pulmonary, bleeding/transfusion, renal, central nervous system, wound, sepsis, Clostridium difficile colitis, graft, or minor [defined as complications having an associated mortality rate <1%]). The association between type of index complication and failure to rescue, secondary complications, reoperation, and postoperative length of stay was evaluated with multivariable, hierarchical regression, and risk of death assessed with shared frailty modeling.

RESULTS

Among 574,195 patients, 5.3% had at least 1 complication (of which 26.1% had secondary complications, and 8.2% had failure to rescue), and 4.5% had a reoperation. Secondary complication (5.0%-61.4%) and failure to rescue (0.8%-34.2%) rates varied by the type of index complication. Relative to index minor complications, index bleeding was most associated with secondary complication (subdistribution hazard ratio 1.4, 95% confidence interval [1.1-1.8]), index cardiac complications were most associated with failure to rescue (odds ratio 45.4 [34.5-59.7]), index graft complications were most associated with reoperation (odds ratio 96.0 [79.5-115.8]), and index pulmonary complications were associated with 2.6 times longer length of stay (incident rate ratio 2.6 [2.6-2.7]). Index cardiac and central nervous system complications were most strongly associated with risk of death (cardiac-hazard ratio 2.45, 95% confidence interval [2.14-2.81]; central nervous system-hazard ratio 1.84 [1.49-2.27]).

CONCLUSION

Different types of index complications are associated with different outcome profiles. This suggests surgical quality improvement efforts should be tailored not only to the type of index complication to be addressed but also to the desired outcome to improve.

The movement of syringes and medication during anesthesiology delivery: An observational study in laparoscopic surgeries

The movements of syringes and medications during an anesthetic case have yet to be systematically documented. We examine how syringes and medication move through the anesthesia work area during a case. We conducted a video-based observational study of 14 laparoscopic surgeries. We defined 'syringe events' as when syringe was picked up and moved. Medications were administered to the patient in only 48 (23.6%) of the 203 medication or syringe events. On average, 14.5 syringe movements occurred in each case. We estimate approximately 4.2 syringe movements for each medication administration. When a medication was administered to the patient (either through the IV pump or the patient port), it was picked up from one of 8 locations in the work area. Our study suggests that the syringe storage locations vary and include irregular locations (e.g., patient bed or provider's pockets). Our study contributes to understanding the complexity in the anesthesia work practices.

Quality and Safety in Nursing: Recommendations From a Systematic Review

ABSTRACT

As a consistent 24-hour presence in hospitals, nurses play a pivotal role in ensuring the quality and safety (Q&S) of patient care. However, a comprehensive review of evidence-based recommendations to guide nursing interventions that enhance the Q&S of patient care is lacking. Therefore, the purpose of our systematic review was to create evidence-based recommendations for the Q&S component of a nursing professional practice model for military hospitals. To accomplish this, a triservice military nursing team used Covidence software to conduct a systematic review of the literature across five databases. Two hundred forty-nine articles met inclusion criteria. From these articles, we created 94 recommendations for practice and identified eight focus areas from the literature: (1) communication; (2) adverse events; (3) leadership; (4) patient experience; (5) quality improvement; (6) safety culture/committees; (7) staffing/workload/work environment; and (8) technology/electronic health record. These findings provide suggestions for implementing Q&S practices that could be adapted to many healthcare delivery systems.

Nationwide Audit of Postoperative Mortality and Complications After Digestive Cancer Surgery: Will New Legal Thresholds be Sufficient?

BACKGROUND

French policymakers recently chose to regulate high-risk digestive cancer surgery (DCS). A minimum of five cases per year should be performed for each of the following types of curative cancer surgery: esophagus/esogastric junction (ECS), stomach (GCS), liver (LCS, metastasis included), pancreas (PCS), and rectum (RCS). This study aimed to evaluate the hypothetical beneficial effects of the new legal minimal volume thresholds on the rates of 90-day postoperative mortality (90POM) for each high-risk DCS.

METHODS

This nationwide observational population-based cohort study used data extracted from the French National Health Insurance Database from 1 January 2015-31 December 2017. Mixed-effects logistic regression models were performed to estimate the independent effect of hospital volume.

RESULTS

During the study period, 61,169 patients (57.1 % male, age 69.7 ±12.2 years) underwent high-risk DCS including ECS (n = 4060), GCS (n = 5572), PCS (n = 8598), LCS (n = 10,988), and RCS (n = 31,951), with 90POM of 6.6 %, 6.9 %, 6.0 %, 5.2 %, and 2.9 %, respectively. For hospitals fulfilling the new criteria, 90POM was lower after adjustment only for LCS (odds ratio [OR],15.2; 95 % confidence interval [CI], 9.5-23.2) vs OR, 7.6; 95 % CI, 5.2-11.0; p < 0.0001) and PCS (OR, 3.6; 95 % CI, 1.7-7.6 vs OR, 2.1; 95 % CI, 1.0-4.4; p<0.0001). With higher thresholds, all DCSs showed a lower adjusted risk of 90POM (e.g., OR, 0.38; 95 % CI, 0.28-0.51) for PCS of 40 or higher.

CONCLUSION

Based on retrospective data, thresholds higher than those promulgated would better improve the safety of high-risk DCS. New policies aiming to further centralize high-risk DCS should be considered, associated with a clear clinical pathway of care for patients to improve accessibility to complex health care in France.

Pro-Con Debate: Universal Versus Selective Continuous Monitoring of Postoperative Patients

In this Pro-Con commentary article, we discuss use of continuous physiologic monitoring for clinical deterioration, specifically respiratory depression in the postoperative population. The Pro position advocates for 24/7 continuous surveillance monitoring of all patients starting in the postanesthesia care unit until discharge from the hospital. The strongest arguments for universal monitoring relate to inadequate assessment and algorithms for patient risk. We argue that the need for hospitalization in and of itself is a sufficient predictor of an individual's risk for unexpected respiratory deterioration. In addition, general care units carry the added risk that even the most severe respiratory events will not be recognized in a timely fashion, largely due to higher patient to nurse staffing ratios and limited intermittent vital signs assessments (e.g., every 4 hours). Continuous monitoring configured properly using a "surveillance model" can adequately detect patients' respiratory deterioration while minimizing alarm fatigue and the costs of the surveillance systems. The Con position advocates for a mixed approach of time-limited continuous pulse oximetry monitoring for all patients receiving opioids, with additional remote pulse oximetry monitoring for patients identified as having a high risk of respiratory depression. Alarm fatigue, clinical resource limitations, and cost are the strongest arguments for selective monitoring, which is a more targeted approach. The proponents of the con position acknowledge that postoperative respiratory monitoring is certainly indicated for all patients, but not all patients need the same level of monitoring. The analysis and discussion of each point of view describes who, when, where, and how continuous monitoring should be implemented. Consideration of various system-level factors are addressed, including clinical resource availability, alarm design, system costs, patient and staff acceptance, risk-assessment algorithms, and respiratory event detection. Literature is reviewed, findings are described, and recommendations for design of monitoring systems and implementation of monitoring are described for the pro and con positions.

Does frailty impact failure-to-rescue in geriatric trauma patients?

BACKGROUND

Failure-to-rescue (FTR), defined as death following a major complication, is a metric of trauma quality. The impact of patient frailty on FTR has not been fully investigated, especially in geriatric trauma patients. This study hypothesized that frailty increased the risk of FTR in geriatric patients with severe injury.

METHODS

A retrospective cohort study was conducted using the TQIP database between 2015 and 2019, including geriatric patients with trauma (age ≥65 years) and an Injury Severity Score (ISS) > 15, who survived ≥48 hours postadmission. Frailty was assessed using the modified 5-item frailty index (mFI). Patients were categorized into frail (mFI ≥ 2) and nonfrail (mFI < 2) groups. Logistic regression analysis and a generalized additive model (GAM) were used to examine the association between FTR and patient frailty after controlling for age, sex, type of injury, trauma center level, ISS, and vital signs on admission.

RESULTS

Among 52,312 geriatric trauma patients, 34.6% were frail (mean mFI: frail: 2.3 vs. nonfrail: 0.9, p < 0.001). Frail patients were older (age, 77 vs. 74 years, p < 0.001), had a lower ISS (19 vs. 21, p < 0.001), and had a higher incidence of FTR compared with nonfrail patients (8.7% vs. 8.0%, p = 0.006). Logistic regression analysis revealed that frailty was an independent predictor of FTR (odds ratio, 1.32; confidence interval, 1.23-1.44; p < 0.001). The GAM plots showed a linear increase in FTR incidence with increasing mFI after adjusting for confounders.

CONCLUSION

This study demonstrated that frailty independently contributes to an increased risk of FTR in geriatric trauma patients. The impact of patient frailty should be considered when using FTR to measure the quality of trauma care.

Cardiac risk stratification and adverse outcomes in surgically managed patients with isolated traumatic spine injuries

INTRODUCTION

As the incidence of traumatic spine injuries has been steadily increasing, especially in the elderly, the ability to categorize patients based on their underlying risk for the adverse outcomes could be of great value in clinical decision making. This study aimed to investigate the association between the Revised Cardiac Risk Index (RCRI) and adverse outcomes in patients who have undergone surgery for traumatic spine injuries.

METHODS

All adult patients (18 years or older) in the 2013-2019 TQIP database with isolated spine injuries resulting from blunt force trauma, who underwent spinal surgery, were eligible for inclusion in the study. The association between the RCRI and in-hospital mortality, cardiopulmonary complications, and failure-to-rescue (FTR) was determined using Poisson regression models with robust standard errors to adjust for potential confounding.

RESULTS

A total of 39,391 patients were included for further analysis. In the regression model, an RCRI ≥ 3 was associated with a threefold risk of in-hospital mortality [adjusted IRR (95% CI): 3.19 (2.30-4.43), p < 0.001] and cardiopulmonary complications [adjusted IRR (95% CI): 3.27 (2.46-4.34), p < 0.001], as well as a fourfold risk of FTR [adjusted IRR (95% CI): 4.27 (2.59-7.02), p < 0.001], compared to RCRI 0. The risk of all adverse outcomes increased stepwise along with each RCRI score.

CONCLUSION

The RCRI may be a useful tool for identifying patients with traumatic spine injuries who are at an increased risk of in-hospital mortality, cardiopulmonary complications, and failure-to-rescue after surgery.

Variation in the definition of 'failure to rescue' from postoperative complications: a systematic review and recommendations for outcome reporting

BACKGROUND

Failure to rescue is the rate of death amongst patients with postoperative complications and has been proposed as a perioperative quality indicator. However, variation in its definition has limited comparisons between studies. We systematically reviewed all surgical literature reporting failure to rescue rates and examined variations in the definition of the 'numerator,' 'denominator,' and timing of failure to rescue measurement.

METHODS

Databases were searched from inception to 31 December 2022. All studies reporting postoperative failure to rescue rates as a primary or secondary outcome were included. We examined the complications included in the failure to rescue denominator, the percentage of deaths captured by the failure to rescue numerator, and the timing of measurement for complications and mortality.

RESULTS

A total of 359 studies, including 212,048,069 patients, were analyzed. The complications included in the failure to rescue denominator were reported in 295 studies (82%), with 131 different complications used. The median number of included complications per study was 10 (interquartile range 8-15). Studies that included a higher number of complications in the failure-to-rescue denominator reported lower failure-to-rescue rates. Death was included as a complication in the failure to rescue the denominator in 65 studies (18%). The median percentage of deaths captured by the failure to rescue calculation when deaths were not included in the denominator was 79%. Complications (52%) and mortality (40%) were mostly measured in-hospital, followed by 30-days after surgery.

CONCLUSION

Failure to rescue is an important concept in the study of postoperative outcomes, although its definition is highly variable and poorly reported. Researchers should be aware of the advantages and disadvantages of different approaches to defining failure to rescue.

Rescue from complications after pancreaticoduodenectomies at a low-volume Caribbean center: Value of tailored peri-pancreatectomy protocols

BACKGROUND

Pancreaticoduodenectomy (PD) is a technically complex operation, with a relatively high risk for complications. The ability to rescue patients from post-PD complications is as a recognized quality measure. Tailored protocols were instituted at our low volume facility in the year 2013.

AIM

To document the rate of rescue from post-PD complications with tailored protocols in place as a measure of quality.

METHODS

A retrospective audit was performed to collect data from patients who experienced major post-PD complications at a low volume pancreatic surgery unit in Trinidad and Tobago between January 1, 2013 and June 30, 2023. Standardized definitions from the International Study Group of Pancreatic Surgery were used to define post-PD complications, and the modified Clavien-Dindo classification was used to classify post-PD complications.

RESULTS

Over the study period, 113 patients at a mean age of 57.5 years (standard deviation [SD] ± 9.23; range: 30-90; median: 56) underwent PDs at this facility. Major complications were recorded in 33 (29.2%) patients at a mean age of 53.8 years (SD: ± 7.9). Twenty-nine (87.9%) patients who experienced major morbidity were salvaged after aggressive treatment of their complication. Four (3.5%) died from bleeding pseudoaneurysm (1), septic shock secondary to a bile leak (1), anastomotic leak (1), and myocardial infarction (1). There was a significantly greater salvage rate in patients with American Society of Anesthesiologists scores ≤ 2 (93.3% vs 25%; P = 0.0024).

CONCLUSION

This paper adds to the growing body of evidence that volume alone should not be used as a marker of quality for patients requiring PD. Despite low volumes at our facility, we demonstrated that 87.9% of patients were rescued from major complications. We attributed this to several factors including development of rescue protocols, the competence of the pancreatic surgery teams and continuous, and adaptive learning by the entire institution, culminating in the development of tailored peri-pancreatectomy protocols.

Failure to rescue following postoperative pneumonia in pediatrics: Is there a racial disparity?

INTRODUCTION

Racial disparities in measures of health and healthcare processes are well described. Limited work exists on disparities in failure to rescue - hospital mortality following a major adverse event. Postoperative pneumonia is a serious, potentially preventable adverse event that often leads to death, i.e., failure to rescue. This study examined the association of racial grouping with failure to rescue following postoperative pneumonia.

METHODS

We utilized the National Surgical Quality Improvement Program-Pediatrics Participant Use Data File to assemble a cohort of children <18 years who underwent inpatient surgery from 2012 to 2022. We included Black and White patients who developed pneumonia following an index surgery. The primary outcome was failure to rescue, defined as mortality following postoperative pneumonia. We used logistic regression models to estimate the odds ratio and 95% confidence intervals of failure to rescue, comparing Black and White children.

RESULTS

The study cohort included 3139 children <18 years who developed pneumonia following inpatient surgery. Of those, 2333 (74.3%) were White and 806 (25.7%) were Black. Failure to rescue occurred in 117 of the children (3.7%); 82 were White (3.5%) and 35 were Black (4.3%). After adjusting for gender, age, American Society of Anesthesiologists Physical Status classification, emergent/urgent vs. elective case status, year of operation, and pre-existing comorbidities, the odds of failure to rescue for Black children with postoperative pneumonia did not differ from White children (adjusted-Odds Ratio: 1.00; 95% Confidence Interval 0.62-1.61; p-value = .992).

CONCLUSION

We found no significant difference in the odds of failure to rescue following postoperative pneumonia between Black or White children. To improve postoperative care for all children and to narrow the racial gap in postoperative mortality, future studies should continue to investigate the association of race with failure to rescue following other postoperative complications.

Improving Statewide Post-Operative Sepsis Performance Measurement Using Hospital Risk Adjustment Within a Surgical Collaborative

Background: The Georgia Quality Improvement Program (GQIP) surgical collaborative participating hospitals have shown consistently poor performance in the post-operative sepsis category of National Surgical Quality Improvement Program data as compared with national benchmarks. We aimed to compare crude versus risk-adjusted post-operative sepsis rankings to determine high and low performers amongst GQIP hospitals. Patients and Methods: The cohort included intra-abdominal general surgery patients across 10 collaborative hospitals from 2015 to 2020. The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) sepsis definition was used among all hospitals for case abstraction and NSQIP data were utilized to train and validate a multivariable risk-adjustment model with post-operative sepsis as the outcome. This model was used to rank GQIP hospitals by risk-adjusted post-operative sepsis rates. Rankings between crude and risk-adjusted post-operative sepsis rankings were compared ordinally and for changes in tertile. Results: The study included 20,314 patients with 595 cases of post-operative sepsis. Crude 30-day post-operative sepsis risk among hospitals ranged from 0.81 to 5.11. When applying the risk-adjustment model which included: age, American Society of Anesthesiology class, case complexity, pre-operative pneumonia/urinary tract infection/surgical site infection, admission status, and wound class, nine of 10 hospitals were re-ranked and four hospitals changed performance tertiles. Conclusions: Inter-collaborative risk-adjusted post-operative sepsis rankings are important to present. These metrics benchmark collaborating hospitals, which facilitates best practice exchange from high to low performers.

Association of race, demographic and socioeconomic factors with failure to rescue after hepato-pancreato-biliary surgery in the United States

BACKGROUND

We aimed to describe the association of patient-related factors such as race, socioeconomic status, and insurance on failure to rescue (FTR) after hepato-pancreato-biliary (HPB) surgeries.

METHODS

Using the National Inpatient Sample, we analyzed 98,788 elective HPB surgeries between 2004 and 2017. Major and minor complications were identified using ICD9/10 codes. We evaluated mortality rates and FTR (inpatient mortality after major complications). We used multivariate logistic regression analysis to assess racial, socioeconomic, and demographic factors on FTR, adjusting for covariates.

RESULTS

Overall, 43 % of patients (n = 42,256) had pancreatic operations, 36% (n = 35,526) had liver surgery, and 21% (n = 21,006) had biliary interventions. The overall major complication rate was 21% (n = 20,640), of which 8% (n = 1655) suffered FTR. Factors independently associated with increased risk for FTR were male sex, older age, higher Charlson Comorbidity Index, Hispanic ethnicity, Asian or other race, lower income quartile, Medicare insurance, and southern region hospitals.

CONCLUSIONS

Medicare insurance, male gender, Hispanic ethnicity, and lower income quartile were associated with increased risk for FTR. Efforts should be made to improve the identification and subsequent treatment of complications for those at high risk of FTR.

Does Failure to Rescue Drive Race/Ethnicity-based Disparities in Survival After Heart Transplantation?

OBJECTIVE

The objective was to assess whether race/ethnicity is an independent predictor of failure to rescue (FTR) after orthotopic heart transplantation (OHT).

SUMMARY BACKGROUND DATA

Outcomes following OHT vary by patient level factors; for example, non-White patients have worse outcomes than White patients after OHT. Failure to rescue is an important factor associated with cardiac surgery outcomes, but its relationship to demographic factors is unknown.

METHODS

Using the United Network for Organ Sharing database, we included all adult patients who underwent primary isolated OHT between 1/1/2006 snd 6/30/2021. FTR was defined as the inability to prevent mortality after at least one of the UNOS-designated postoperative complications. Donor, recipient, and transplant characteristics, including complications and FTR, were compared across race/ethnicity. Logistic regression models were created to identify factors associated with complications and FTR. Kaplan Meier and adjusted Cox proportional hazards models evaluated the association between race/ethnicity and posttransplant survival.

RESULTS

There were 33,244 adult, isolated heart transplant recipients included: the distribution of race/ethnicity was 66% (n=21,937) White, 21.2% (7,062) Black, 8.3% (2,768) Hispanic, and 3.3% (1,096) Asian. The frequency of complications and FTR differed significantly by race/ethnicity. After adjustment, Hispanic recipients were more likely to experience FTR than White recipients (OR 1.327, 95% CI[1.075-1.639], P =0.02). Black recipients had lower 5-year survival compared with other races/ethnicities (HR 1.276, 95% CI[1.207-1.348], P <0.0001).

CONCLUSIONS

In the US, Black recipients have an increased risk of mortality after OHT compared with White recipients, without associated differences in FTR. In contrast, Hispanic recipients have an increased likelihood of FTR, but no significant mortality difference compared with White recipients. These findings highlight the need for tailored approaches to addressing race/ethnicity-based health inequities in the practice of heart transplantation.

Utility of Hospital Failure to Rescue for Analyzing Variation in Pediatric Postoperative Mortality

OBJECTIVES

To evaluate the association between pediatric hospital performances in terms of failure to rescue (FTR), defined as postoperative mortality after a surgical complication, and mortality among patients without a surgical complication.

DESIGN

Retrospective cohort study.

SETTING

Forty-eight academic, pediatric hospitals; data obtained from Pediatric Health Information System database (Child Health Corporation of America, Shawnee Mission, KS) (2012-2020).

PATIENTS

Children who underwent at least one of 57 high-risk operations associated with significant postoperative mortality.

EXPOSURES

Hospitals were stratified into quintiles of reliability adjusted FTR (lower than average FTR in quintile 1 [Q1], higher than average FTR in quintile 5 [Q5]). Multivariable hierarchical regression was used to evaluate the association between hospital FTR performance and mortality among patients who did not have a surgical complication.

MEASUREMENTS AND MAIN RESULTS

Among 203,242 children treated across 48 academic hospitals, the complication and overall postoperative mortality rates were 8.8% and 2.3%, respectively. Among patients who had a complication, the FTR rate was 8.8%. Among patients who did not have a complication, the mortality rate was 1.7%. There was a 6.5-fold increase in reliability adjusted FTR between the lowest and highest performing hospitals (lowest FTR hospital-2.7%; 95% CI [1.6-3.9]; highest FTR hospital-17.8% [16.8-18.8]). Complex chronic conditions were highly prevalent across hospitals (Q1, 72.7%; Q2, 73.8%; Q3, 72.2%; Q4, 74.0%; Q5, 74.8%; trend test p < 0.01). Relative to Q1 hospitals, the odds of mortality in the absence of a postoperative complication significantly increased by 33% at Q5 hospitals (odds ratio 1.33; 95% CI [1.07-1.66]). This association was consistent when limited to patients with a complex chronic condition and neonates.

CONCLUSION

FTR may be a useful and valid surgical quality measure for pediatric surgery, even when considering patients without a postoperative complication. These findings suggest practices and processes for preventing FTR at high performing pediatric hospitals might help mitigate the risk of postoperative mortality even in the absence of a postoperative complication.

Predictors of Failure to Rescue After Postoperative Respiratory Failure: A Retrospective Cohort Analysis of 13,047 Patients Using the ACS-NSQIP Dataset

INTRODUCTION

Death after suffering a postoperative complication (failure to rescue) is an area of concern, and its occurrence after postoperative respiratory failure (PRF) is not well defined. We seek to identify the predictors of failure to rescue in patients who develop PRF.

METHODS

A retrospective cohort study of adults undergoing noncardiac surgery who developed PRF (postoperative unplanned intubation and receipt of mechanical ventilation for longer than 48 h) was conducted using the American College of Surgeons National Surgical Quality Improvement Project database. Predictors of failure to rescue after PRF were identified using the Least Absolute Shrinkage and Selection Operator (LASSO)-penalized variable selection method, with the Bayesian information criterion, in the context of a multiple logistic regression model (with Firth's bias correction).

RESULTS

Of the 13,047 patients that formed our final evaluable study cohort, 3669 (28.1%) patients died within 30 days of surgery. We identified age, sex, American Society of Anesthesiologists physical status, presence of preoperative ascites, disseminated cancer, bleeding disorders, elevated preoperative creatinine, and low preoperative prealbumin levels as predictors of failure to rescue. The area under the curve for the final model was 0.6804, with a standard error of 0.0104 (95% CI area under the curve: 0.6600 to 0.7008).

CONCLUSIONS

We observed that almost 30% of patients that develop respiratory failure after noncardiac surgery die within 30 days of surgery. The validated eight-variable perioperative predictive model provides a risk estimate for death after PRF and may be useful for the purposes of preoperative planning, prognostication, decision making and resource allocation in patients who develop this complication.

The impact of rural structural and community health factors on postmastectomy complications among south central Appalachian breast cancer patients

PURPOSE

The study examined how structural and community health factors, including primary care physicians (PCP), food insecurity, diabetes, and mortality rate per county, are linked to the number and severity of postmastectomy complications among south central Appalachian breast cancer patients depending on rural status.

METHODS

Data was obtained through a retrospective review of 473 breast cancer patients that underwent a mastectomy from 2017 to 2021. Patient's ZIP Code was used to determine their rural-urban community area code and their county of residence for census data. We conducted a zero inflated Poisson regression.

FINDINGS

Results demonstrated that patients in small rural/isolated areas with low (B = -4.10, SE = 1.93, OR = 0.02, p = 0.03) to average (B = -2.67, SE = 1.32, OR = 0.07, p = 0.04) food insecurity and average (B = -2.67, SE = 1.32, OR = 0.07, p = 0.04) to high (B = -10.62, SE = 4.71, OR = 0.00, p = 0.02) PCP have significantly fewer postmastectomy complications compared to their urban counterparts. Additionally, patients residing in small rural/isolated areas with high (B = 4.47, SE = 0.49, d = 0.42, p < 0.001) diabetes and low mortality (B = 5.70, SE = 0.58, d = 0.45, p < 0.001) rates have significantly more severe postmastectomy complications.

CONCLUSION

These findings demonstrate that patients who reside in small/rural isolated areas may experience fewer and less severe postmastectomy when there is certain optimal structural and community health factors present compared to their urban counterparts. Oncologic care teams could utilize this information in routine consult for risk assessment and mitigation. Future research should further examine additional risks for postmastectomy complications.

Outcomes of elective liver surgery worldwide: a global, prospective, multicenter, cross-sectional study

BACKGROUND

The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes.

METHODS

LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January-December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien-Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141).

RESULTS

A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively.

CONCLUSIONS

This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives.

More problems, more money: Identifying and predicting high-cost rescue after colorectal surgery

Background

Successful rescue after elective surgery is associated with increased healthcare costs, but costs vary widely. Treating all rescue events the same may overlook targeted opportunities for improvement. The purpose of this study was to predict high-cost rescue after elective colorectal surgery.

Methods

We identified adult patients in the National Inpatient Sample (2016-2021) who underwent elective colectomy or proctectomy. Rescued patients were defined as those who underwent additional major procedures. Three groups were stratified: 1) uneventful recovery; 2) Low-cost rescue; 3) High-cost rescue. Multivariable Poisson regression was used to identify preoperative clinical predictors of high-cost versus low-cost rescue.

Results

We identified 448,590 elective surgeries, and rescued patients composed 4.8 %(21,635) of the total sample. The median increase in costs in rescued patients was $25,544(p < 0.001). Median total inpatient costs were $95,926 in the most expensive rescued versus $34,811 in the less expensive rescued versus $16,751 in the uneventfully discharged(p < 0.001). When comparing the secondary procedures between the less expensive and most expensive rescued groups, the most expensive had an increased proportion of reoperation (73.4 % versus 53.0 %,p < 0.001). When controlling for other factors and stratification by congestive heart failure due to an interaction effect, a reoperation was independently associated with high-cost rescue (RR with CHF = 3.29,95%CI:2.69-4.04; RR without CHF = 2.29,95%CI:1.97-2.67).

Conclusions

High-cost rescue after colorectal surgery is associated with disproportionately greater healthcare utilization and reoperation. For cost-conscious care, preemptive strategies that reduce reoperation-related complications can be prioritized.

Racial Disparities in Pediatric Mortality Following Transfusion Within 72 Hours of Operation

BACKGROUND

Postoperative bleeding and transfusion are correlated with mortality risk. Furthermore, postoperative bleeding may often initiate the cascade of complications that leads to death. Given that minority children have increased risk of surgical complications, this study aimed to investigate the association of race with pediatric surgical mortality following postoperative transfusion.

METHODS

We used the NSQIP-P PUF to assemble a retrospective cohort of children <18 who underwent inpatient surgery during 2012-2021. We included White, Black, Hispanic, and 'Other' children who received a transfusion within 72 h of surgery. The primary outcome was defined as all-cause mortality within 30 days following the primary surgical procedure. Using logistic regression models, we estimated the risk-adjusted odds ratio (aOR) and 95% confidence intervals (CI) of mortality, comparing each racial/ethnic cohort to White children.

RESULTS

A total of 466,230 children <18 years of age underwent inpatient surgical procedures from 2012 to 2021. Of these, 46,200 required transfusion and were included in our analysis. The majority of patients were non-Hispanic White (64.6%, n = 29,850), while 18.9% (n = 8752) were non-Hispanic Black, 11.7% (n = 5387) were Hispanic, and 4.8% (n = 2211) were 'Other' race. The overall rate of mortality following transfusion was 2.5%. White children had the lowest incidence of mortality (2.0%), compared to children of 'Other' race (2.5%), Hispanic children (3.1%), and Black children (3.6%). After adjusting for sex, age, comorbidities, case status, preoperative transfusion within 48 h, and year of operation, we found that Black children experienced 1.24 times the odds of mortality following a postoperative transfusion compared to a White child (aOR: 1.24; 95%CI, 1.03-1.51; P = 0.025). Hispanic children were also significantly more likely to die following a postoperative transfusion than White children (aOR: 1.19; 95%CI, 1.02-1.39; P = 0.027).

CONCLUSION

We found that minority children who required a postoperative transfusion had a higher odds of death than White children. Future studies should explore adverse events following postoperative transfusion and the differences in their management by race that may contribute to the higher mortality rate for minority children.

Outcomes of open repair for descending thoracic and thoracoabdominal aortic aneurysm in recent 10 years: experience of a high-volume centre in Korea

OBJECTIVES

Although recent studies and guidelines suggest the preferred outcomes after surgical repair of thoracic aortic aneurysm (TAA) and thoracoabdominal aortic aneurysm (TAAA), published results are limited to those from high-volume hospitals and based on old data gathered before optimal management was established. Here, we analysed our outcomes over the previous 10 years from cases of open TAA and TAAA repair to offer updated and real-world results of those complex procedures performed in a high-volume centre.

METHODS

From November 2013 to April 2022, 212 consecutive adult patients who underwent open TAA and TAAA repair were enrolled. We analysed early and late outcomes after surgery, including postoperative complications and mortality.

RESULTS

There were 154 (73%) men, and the median age at surgery was 61 years. Intraoperative death occurred in 1 patient due to uncontrolled bleeding. Nine patients (4%) died during follow-up, and the survival estimates at 5 years were 94 ± 3% and 95 ± 3% after descending TAA and TAAA repair, respectively. Ten patients (4%) suffered from spinal cord ischaemic injury (9 with paraplegia and 1 with paresthesia), but permanent paraplegia persisted in only 1 case.

CONCLUSIONS

We report very low postoperative complication rates and excellent early and late survival rates after open TAA and TAAA repair from our recent 10-year data analysis. These findings may assist when choosing treatment options for these complicated diseases.

Temporal trends of failure-to-rescue following perioperative complications in vulvar cancer surgery in the United States

OBJECTIVE

Failure-to-rescue, defined as mortality following a perioperative complication, is a perioperative quality indicator studied in various surgeries, but not in vulvar cancer surgery. The objective of this study was to assess failure-to-rescue in patients undergoing surgical therapy for vulvar cancer.

METHODS

This cross-section study queried the National Inpatient Sample. The study population was 31,077 patients who had surgical therapy for vulvar cancer from 1/2001-9/2015. The main outcomes were (i) perioperative morbidity (29 indicators) and (ii) mortality following a perioperative complication during the index admission for vulvar surgery (failure-to-rescue), assessed with a multivariable binary logistic regression model.

RESULTS

The cohort-level median age was 69 years, and 14,337 (46.1%) had medical comorbidity. Perioperative complications were reported in 4736 (15.2%) patients during the hospital admission for vulvar surgery. In multivariable analysis, patient factors including older age, medical comorbidity, and morbid obesity, and treatment factors with prior radiotherapy and radical vulvectomy were associated with perioperative complications (P < 0.05). The number of patients with morbid obesity, higher comorbidity index, and prior radiotherapy increased over time (P-trends < 0.001). Among 4736 patients who developed perioperative complications, 55 patients died during the hospital admission for vulvar surgery (failure-to-rescue rate, 1.2%). In multivariable analysis, cardiac arrest (adjusted-odds ratio [aOR] 27.25), sepsis or systemic inflammatory response syndrome (aOR 11.54), pneumonia (aOR 6.03), shock (aOR 4.37), and respiratory failure (aOR 3.10) were associated with failure-to-rescue (high-risk morbidities). There was an increasing trend of high-risk morbidities from 2.0% to 3.7% over time, but the failure-to-rescue from high-risk morbidities decreased from 9.1% to 2.8% (P-trend < 0.05).

CONCLUSION

Vulvar cancer patients undergoing surgical treatment had increased comorbidity over time with an increase in high-risk complications. However, failure-to-rescue rate has decreased significantly.

Failure to rescue among octogenarians undergoing cardiac surgery in the United States

BACKGROUND

A rapidly growing population, octogenarians are considered at high-risk for mortality and complications after cardiac surgery. Given the recent addition of failure to rescue as a Society of Thoracic Surgeons quality metric, a better understanding of patient and operative factors predictive of failure to rescue in this cohort is warranted.

METHODS

The 2010-2020 Nationwide Readmissions Database was used to identify all patients ≥80 years undergoing first-time, elective coronary artery bypass grafting or concomitant valve operations. Patients experiencing failure to rescue, defined as mortality after a major or minor complication, were classified as Failure to Rescue (others: Non-Failure to Rescue). Multivariable regression models were developed to ascertain significant perioperative factors associated with failure to rescue.

RESULTS

Of ∼562,794 octogenarian patients, 76,473 (13.6%) developed complications. Of these, 7,055 (9.2%) experienced failure to rescue. The incidence of failure to rescue decreased across the study time course (9.7% in 2010 to 7.6% in 2019, P = .001). After risk adjustment, age (adjusted odds ratio, 1.05/year; 95% confidence interval, 1.03-1.07), female sex (adjusted odds ratio, 1.40; 95% confidence interval, 1.27-1.53), congestive heart failure (adjusted odds ratio, 1.54; 95% confidence interval, 1.38-1.71), late-stage kidney disease (adjusted odds ratio, 2.38; 95% confidence interval, 1.79-3.17), liver disease (adjusted odds ratio, 9.59; 95% confidence interval, 8.17-11.26), and cerebrovascular disease (adjusted odds ratio, 2.42; 95% confidence interval, 2.12-2.76) were associated with failure to rescue. Relative to isolated coronary artery bypass grafting, combined coronary artery bypass grafting-valve (adjusted odds ratio, 1.67; 95% confidence interval, 1.43-1.95) and multi-valve procedures (adjusted odds ratio, 2.23; 95% confidence interval, 1.75-2.85) were linked with greater odds of failure to rescue. There was no association between failure to rescue and hospital volume.

CONCLUSION

Despite improvements in perioperative management, failure to rescue occurs in ∼9% of octogenarians undergoing elective cardiac operations. Although incidence has declined over the past decade, the continued prevalence of failure to rescue underscores the need for novel risk assessments and targeted interventions.

National trend in failure to rescue after cardiac surgeries

OBJECTIVES

Failure to rescue (FTR), defined as postoperative inpatient death after potentially treatable major complications, is a nationally endorsed quality of care measure, however, the effect of practice change on FTR is unknown. In this study, we aimed to define the FTR trend after cardiac surgery in the United States.

METHODS

In this retrospective analysis of the National Inpatient Sample database we identified adult patients who underwent cardiac surgeries in the United States between 2000 and 2018, defined incidence and trends in FTR adjusted for sex, age, diagnosis-related group, and comorbidity. Trends were analyzed using Joinpoint (Statistical Methodology and Applications Branch, Surveillance Research Program, National Cancer Institute) regression software.

RESULTS

The study included 6,185,032 hospitalizations for cardiac surgeries. Risk-adjusted FTR after deep venous thromboembolism/pulmonary embolism and sepsis has declined from 2000 to 2018 (annual percent change [APC] = -6.4% and -11.6%, respectively; P < .001). After pneumonia, FTR has increased significantly since 2011 (APC = 9.3%; P < .001). Since 2012, FTR due to gastrointestinal hemorrhage has increased substantially (APC = 15.9%; P < .001). The risk-adjusted FTR rate in patients 75 years of age or older significantly declined until 2011 (APC = -12.6%; P < .001) and became comparable with the FTR rate of younger patients by the end of the study.

CONCLUSIONS

There have been significant reductions in FTR in elderly patients and a reduction in postprocedural mortality associated with sepsis and venous thromboembolism overall after cardiac surgery. This might provide evidence supporting national targeted quality metrics and care bundles for complications such as pneumonia and gastrointestinal bleeding, which had an increasing FTR.

Integration of the social determinants of health into quality indicators for colorectal cancer surgery: a scoping review protocol

INTRODUCTION

Quality monitoring is a critical component of high-performing cancer care systems. Quality indicators (QIs) are standardised, evidence-based measures of healthcare quality that allow healthcare systems to track performance, identify gaps in healthcare delivery and inform areas of priority for strategic planning. Social structures and economic systems that allow for unequal access to power and resources that shape health and health inequities can be described through the social determinants of health (SDoH) framework. Therefore, granular analysis of healthcare quality through SDoH frameworks is required to identify patient subgroups who may experience health inequity. Given the high burden of disease of colorectal cancer (CRC) and well-defined cancer care pathways, CRC is often the first disease site targeted by health systems for quality improvement. The objective of this review is to examine how SDoH have been integrated into QIs for CRC surgery. This review aims to address three primary questions: (1) Have SDoH been integrated into the development, reporting and assessment of CRC surgery QIs? (2) When integrated, what measures and statistical methods have been applied? (3) In which direction do individual SDoH influence QIs outputs?

METHODS

This review will follow Arksey and O'Malley frameworks for scoping reviews. We will search MEDLINE, EMBASE, HealthSTAR databases for papers that examine QIs for CRC surgery applicable to healthcare systems from database inception until January 2023. Interventional trials, prospective and retrospective observational studies, reviews, case series and qualitative study designs will be included. Two authors will independently review all titles, abstracts and full texts to determine which studies meet the inclusion criteria.

ETHICS & DISSEMINATION

No ethics approval is required for this review. Results will be disseminated through scientific presentation and relevant conferences targeted for researchers examining healthcare quality and equity in cancer care.

Network prediction of surgical complication clusters: a prospective multicenter cohort study

Complicated relationships exist in both occurrence and progression of surgical complications, which are difficult to account for using a separate quantitative method such as prediction or grading. Data of 51,030 surgical inpatients were collected from four academic/teaching hospitals in a prospective cohort study in China. The relationship between preoperative factors, 22 common complications, and death was analyzed. With input from 54 senior clinicians and following a Bayesian network approach, a complication grading, cluster-visualization, and prediction (GCP) system was designed to model pathways between grades of complication and preoperative risk factor clusters. In the GCP system, there were 11 nodes representing six grades of complication and five preoperative risk factor clusters, and 32 arcs representing a direct association. Several critical targets were pinpointed on the pathway. Malnourished status was a fundamental cause widely associated (7/32 arcs) with other risk factor clusters and complications. American Society of Anesthesiologists (ASA) score ⩾3 was directly dependent on all other risk factor clusters and influenced all severe complications. Grade III complications (mainly pneumonia) were directly dependent on 4/5 risk factor clusters and affected all other grades of complication. Irrespective of grade, complication occurrence was more likely to increase the risk of other grades of complication than risk factor clusters.

"Failure to Rescue" following Colorectal Cancer Resection: Variation and Improvements in a National Study of Postoperative Mortality

OBJECTIVE

To examine variation in "failure to rescue" (FTR) as a driver of differences in mortality between centres and over time for patients undergoing colorectal cancer surgery.

BACKGROUND

Wide variation exists in postoperative mortality following colorectal cancer surgery. FTR has been identified as an important determinant of variation in postoperative outcomes. We hypothesized that differences in mortality both between hospitals and over time are driven by variation in FTR.

METHODS

A national population-based study of patients undergoing colorectal cancer resection from 2010 to 2019 in Aotearoa New Zealand was conducted. Rates of 90-day FTR, mortality, and complications were calculated overall, and for surgical and nonoperative complications. Twenty District Health Boards (DHBs) were ranked into quartiles using risk- and reliability-adjusted 90-day mortality rates. Variation between DHBs and trends over the 10-year period were examined.

RESULTS

Overall, 15,686 patients undergoing resection for colorectal adenocarcinoma were included. Increased postoperative mortality at high-mortality centers (OR 2.4, 95% CI 1.8-3.3) was driven by higher rates of FTR (OR 2.0, 95% CI 1.5-2.8), and postoperative complications (OR 1.4, 95% CI 1.3-1.6). These trends were consistent across operative and nonoperative complications. Over the 2010 to 2019 period, postoperative mortality halved (OR 0.5, 95% CI 0.4-0.6), associated with a greater improvement in FTR (OR 0.5, 95% CI 0.4-0.7) than complications (OR 0.8, 95% CI 0.8-0.9). Differences between centers and over time remained when only analyzing patients undergoing elective surgery.

CONCLUSION

Mortality following colorectal cancer resection has halved over the past decade, predominantly driven by improvements in "rescue" from complications. Differences in FTR also drive hospital-level variation in mortality, highlighting the central importance of "rescue" as a target for surgical quality improvement.

What defines a great surgeon? A survey study confronting perspectives

Background

The definition of a great surgeon is usually reported by surgeons themselves. The objective of the study was to define a multifaceted definition of a great surgeon, by confronting patients', healthcare workers', and surgeons' perspectives.

Study design

An online open-ended questionnaire was created to identify three qualities and three shortcomings defining a great surgeon. Age, gender, and profession of respondents were collected. Responses with a similar meaning were combined into word groups and labeled within four themes: human qualities, technical surgical skills (TSS), non-technical skills (NTS), and knowledge. Multivariate analyses were conducted between themes and respondent characteristics.

Results

Four thousand seven hundred and sixty qualities and 4,374 shortcomings were obtained from 1,620 respondents including 385 surgeons, 291 patients, 565 operating theater (OT) health professionals, and 379 non-OT health professionals. The main three qualities were dexterity (54% of respondents), meticulousness (18%), and empathy (18%). There was no significant difference between professional categories for TSS. Compared with surgeons, non-OT health professionals and patients put more emphasis on human qualities (29 vs. 39% and 42%, respectively, p < .001). OT health professionals referred more to NTS than surgeons (35 vs. 22%, p < 0.001). Knowledge was more important for surgeons (19%) than for all other professional categories (p < 0.001).

Conclusions

This survey illustrates the multifaceted definition of a great surgeon. Even if dexterity is a major quality, human qualities are of paramount importance. Knowledge seems to be underestimated by non-surgeons, although it essential to understand the disease and preparing the patient and OT team for the procedure.

Developing and validating a machine learning ensemble model to predict postoperative delirium in a cohort of high-risk surgical patients: A secondary cohort analysis

BACKGROUND

Postoperative delirium (POD) has a negative impact on prognosis, length of stay and the burden of care. Although its prediction and identification may improve postoperative care, this need is largely unmet in the Brazilian public health system.

OBJECTIVE

To develop and validate a machine-learning prediction model and estimate the incidence of delirium. We hypothesised that an ensemble machine-learning prediction model that incorporates predisposing and precipitating features could accurately predict POD.

DESIGN

A secondary analysis nested in a cohort of high-risk surgical patients.

SETTING

An 800-bed, quaternary university-affiliated teaching hospital in Southern Brazil. We included patients operated on from September 2015 to February 2020.

PATIENTS

We recruited 1453 inpatients with an all-cause postoperative 30-day mortality risk greater than 5% assessed preoperatively by the ExCare Model.

MAIN OUTCOME MEASURE

The incidence of POD classified by the Confusion Assessment Method, up to 7 days postoperatively. Predictive model performance with different feature scenarios were compared with the area under the receiver operating characteristic curve.

RESULTS

The cumulative incidence of delirium was 117, giving an absolute risk of 8.05/100 patients. We developed multiple machine-learning nested cross-validated ensemble models. We selected features through partial dependence plot analysis and theoretical framework. We treated the class imbalance with undersampling. Different feature scenarios included: 52 preoperative, 60 postoperative and only three features (age, preoperative length of stay and the number of postoperative complications). The mean areas (95% confidence interval) under the curve ranged from 0.61 (0.59 to 0.63) to 0.74 (0.73 to 0.75).

CONCLUSION

A predictive model composed of three indicative readily available features performed better than those with numerous perioperative features, pointing to its feasibility as a prognostic tool for POD. Further research is required to test the generalisability of this model.

Weight loss during neoadjuvant therapy and short-term outcomes after esophagectomy: a retrospective cohort study

BACKGROUND

Neoadjuvant therapy (NAT) has become common worldwide for resectable advanced esophageal cancer and frequently involves weight loss. Although failure to rescue (death after major complications) is known as an emerging surgical quality measure, little is known about the impact of weight loss during NAT on failure to rescue. This retrospective study aimed to investigate the association of weight loss during NAT and short-term outcomes, including failure to rescue after esophagectomy.

MATERIALS AND METHODS

Patients who underwent esophagectomy after NAT between July 2010 and March 2019 were identified from a Japanese nationwide inpatient database. Based on quartiles of percent weight change during NAT, patients were grouped into four categories of gain, stable, small loss, and loss (>4.5%). The primary outcomes were failure to rescue and in-hospital mortality. The secondary outcomes were major complications, respiratory complications, anastomotic leakage, and total hospitalization costs. Multivariable regression analyses were used to compare outcomes between the groups, adjusting for potential confounders, including baseline BMI.

RESULTS

Among 15 159 eligible patients, in-hospital mortality and failure to rescue occurred in 302 (2.0%) and 302/5698 (5.3%) patients, respectively. Weight loss (>4.5%) compared to gain was associated with increased failure to rescue and in-hospital mortality [odds ratios 1.55 (95% CI: 1.10-2.20) and 1.53 (1.10-2.12), respectively]. Weight loss was also associated with increased total hospitalizations costs, but not with major complications, respiratory complications, and anastomotic leakage. In subgroup analyses, regardless of baseline BMI, weight loss (>4.8% in nonunderweight or >3.1% in underweight) was a risk factor for failure to rescue and in-hospital mortality.

CONCLUSION

Weight loss during NAT was associated with failure to rescue and in-hospital mortality after esophagectomy, independent of baseline BMI. This emphasizes the importance of weight loss measurement during NAT to assess the risk for a subsequent esophagectomy.

Quality indicators for anesthesia and perioperative medicine

PURPOSE OF REVIEW

Routine monitoring of care quality is fundamental considering the high reported rates of preventable perioperative morbidity and mortality. However, no set of valid and feasible quality indicators is available as the gold standard for comprehensive routine monitoring of the overall quality of perioperative care. The purpose of this review is to describe underlying difficulties, to summarize current trends and initiatives and to outline the perspectives in support of suitable perioperative quality indicators.

RECENT FINDINGS

Most perioperative quality indicators used in the clinical setting are based on low or no evidence. Evidence-based perioperative quality indicators validated for research purposes are not always applicable in routine care. Developing a core set of perioperative quality indicators for clinical practice may benefit from matching feasible routine indicators with evidence-based indicators validated for research, from evaluating additional new indicators, and from including patients' views.

SUMMARY

A core set of valid and feasible quality indicators is essential for monitoring perioperative care quality. The development of such a set may benefit from matching evidence-based indicators with feasible standard indicators and from including patients' views.

Hospital Performance on Failure to Rescue Correlates With Likelihood of Home Discharge

INTRODUCTION

Failure to rescue (FTR) (avoiding death after complications) has been proposed as a measure of hospital quality. Although surviving complications is important, not all rescues are created equal. Patients also place considerable values on being able to return home after surgery and resume their normal lives. From a systems standpoint, nonhome discharge to skilled nursing and other facilities is the biggest driver of Medicare costs. We wanted to determine whether hospitals' ability to keep patients alive after complications was associated with higher rates of home discharge. We hypothesized that hospitals with higher rescue rates would also be more likely to discharge patients home after surgery.

METHODS

We conducted a retrospective cohort study using the nationwide inpatient sample. We included 1,358,041 patients ≥18 y old who had elective major surgery (general, vascular, orthopedic) at 3818 hospitals from 2013 to 2017. We predicted the correlation between a hospital's performance (rank) on FTR and its rank in terms of home discharge rate.

RESULTS

The cohort had a median age of 66 y (interquartile range [IQR] 58-73), and 77.9% of patients were Caucasian. Most patients (63.6%) were treated at urban teaching institutions. The surgical case mix included patients having colorectal (146,993 patients; 10.8%), pulmonary (52,334; 3.9%), pancreatic (13,635; 1.0%), hepatic (14,821; 1.1%), gastric (9182; 0.7%), esophageal (4494; 0.3%), peripheral vascular bypass (29,196; 2.2%), abdominal aneurysm repair (14,327; 1.1%), coronary artery bypass (61,976; 4.6%), hip replacement (356,400; 26.2%), and knee replacement (654,857; 48.2%) operations. The overall mortality was 0.3%, the average hospital complication rate was 15.9%, the median hospital rescue rate was 99% (IQR 70%-100%), and the median hospital rate of home discharge was 80% (IQR 74%-85%).There was a small but positive correlation between hospitals' performance on the FTR metric and the likelihood of home discharge after surgery (r = 0.0453; P = 0.006). When considering hospital rates of discharge to home following a postoperative complication, there was a similar correlation between rescue rates and probability of home discharge (r = 0.0963; P < 0.001). However, on sensitivity analysis excluding orthopedic surgery, there was a stronger correlation between rescue rates and home discharge rate (r = 0.4047, P < 0.001).

CONCLUSIONS

We found a small correlation between a hospital's ability to rescue patients from complication and that hospital's likelihood of discharging patients home after surgery. When excluding orthopedic operations from the analysis, this correlation strengthened. Our findings suggest that efforts to reduce mortality after complications will likely also help patients return home more frequently after complex surgery. However, more work needs to be done to identify successful programs and other patient and hospital factors that affect both rescue and home discharge.

Impact of hospital volume in liver surgery on postoperative mortality and morbidity: nationwide study

BACKGROUND

This nationwide retrospective study was undertaken to evaluate impact of hospital volume and influence of liver transplantation activity on postoperative mortality and failure to rescue after liver surgery.

METHODS

This was a retrospective study of patients who underwent liver resection between 2011 and 2019 using a nationwide database. A threshold of surgical activities from which in-hospital mortality declines was calculated. Hospitals were divided into high- and low-volume centres. Main outcomes were in-hospital mortality and failure to rescue.

RESULTS

Among 39 286 patients included, the in-hospital mortality rate was 2.8 per cent. The activity volume threshold from which in-hospital mortality declined was 25 hepatectomies. High-volume centres (more than 25 resections per year) had more postoperative complications but a lower rate of in-hospital mortality (2.6 versus 3 per cent; P < 0.001) and failure to rescue (5 versus 6.3 per cent; P < 0.001), in particular related to specific complications (liver failure, biliary complications, vascular complications) (5.5 versus 7.6 per cent; P < 0.001). Liver transplantation activity did not have an impact on these outcomes.

CONCLUSION

From more than 25 liver resections per year, rates of in-hospital mortality and failure to rescue declined. Management of specific postoperative complications appeared to be better in high-volume centres.

Failure to Rescue: A Quality Metric for Cardiac Surgery and Cardiovascular Critical Care

Failure to rescue, defined as mortality after a surgical complication, is a widely accepted quality metric across many specialties and is becoming an important metric in cardiac surgery. The failure to rescue metric provides a target for improvements in patient outcomes after complications occur. To be used appropriately, the failure to rescue metric must be defined using a prespecified set of life-threatening and rescuable complications. Successful patient rescue requires a systematic approach of complication recognition, timely escalation of care, effective medical management, and mitigation of additional complications. This process requires contributions from cardiac surgeons, intensivists, and other specialists including cardiologists, neurologists, and anaesthesiologists. Factors that affect failure to rescue rates in cardiac surgery and cardiovascular critical care include nurse staffing ratios, intensivist coverage, advanced specialist support, hospital and surgical volume, the presence of trainees, and patient comorbidities. Strategies to improve patient rescue include working to understand the mechanisms of failure to rescue, anticipating postoperative complications, prioritizing microsystem factors, enhancing early escalation of care, and educating and empowering junior clinicians. When used appropriately, the failure to rescue quality metric can help institutions focus on improving processes of care that minimize morbidity and mortality from rescuable complications after cardiac surgery.

Am I safe? An Interpretative Phenomenological Analysis of Vulnerability as Experienced by Patients With Complications Following Surgery

Abdominal surgery carries with it risks of complications. Little is known about patients' experiences of post-surgical deterioration. There is a real need to understand the psychosocial as well as the biological aspects of deterioration in order to improve care and outcomes for patients. Drawing on in-depth interviews with seven abdominal surgery survivors, we present an idiographic account of participants' experiences, situating their contribution to safety within their personal lived experiences and meaning-making of these episodes of deterioration. Our analysis reveals an overarching group experiential theme of vulnerability in relation to participants' experiences of complications after abdominal surgery. This encapsulates the uncertainty of the situation all the participants found themselves in, and the nature and seriousness of their health conditions. The extent of participants' vulnerability is revealed by detailing how they made sense of their experience, how they negotiated feelings of (un)safety drawing on their relationships with family and staff and the legacy of feelings they were left with when their expectations of care (care as imagined) did not meet the reality of their experiences (care as received). The participants' experiences highlight the power imbalance between patients and professionals in terms of whose knowledge counts within the hospital context. The study reveals the potential for epistemic injustice to arise when patients' concerns are ignored or dismissed. Our data has implications for designing strategies to enable escalation of care, both in terms of supporting staff to deliver compassionate care, and in strengthening patient and family involvement in rescue processes.

A Pragmatic Method for Measuring Inpatient Complications and Complication-Specific Mortality

OBJECTIVES

The primary objective of this study was to develop hospital-level metrics of major complications associated with mortality that allows for the identification of opportunities for improvement. The secondary objective is to improve upon current metrics for failure to rescue (i.e., death from serious but treatable complications.).

METHODS

Agency for Healthcare Research and Quality metrics served as the basis for identifying specific complications related to major organ system morbidity associated with death. Complication-specific occurrence rates, observed mortality, and risk-adjusted mortality indices were calculated for the study institution and 182 peer organizations using component International Classification of Disease, Tenth Revision codes. Data were included for adults over a 4-year period, with exclusion of hospice patients and complications present on admission. Temporal visualizations of each metric were used to compare past and recent performance at the study hospital and in comparison to peers.

RESULTS

The complication-specific method showed statistically significant differences in the study hospital occurrence rates and associated mortality rates compared with peer institutions. The monthly control-chart presentation of these metrics provides assessment of hospital-level interventions to prevent complications and/or reduce failure to rescue deaths.

CONCLUSIONS

The method described supplements existing metrics of serious complications that occur during the course of acute hospitalization allowing for enhanced visualization of opportunities to improve care delivery systems. This method leverages existing measure components to minimize reporting burden. Monthly time-series data allow interventions to prevent and/or rescue patients to be rapidly assessed for impact.

Complications and Failure to Rescue After Inpatient Pediatric Surgery

OBJECTIVE

To describe the frequency and patterns of postoperative complications and FTR after inpatient pediatric surgical procedures and to evaluate the association between number of complications and FTR.

SUMMARY AND BACKGROUND

FTR, or a postoperative death after a complication, is currently a nationally endorsed quality measure for adults. Although it is a contributing factor to variation in mortality, relatively little is known about FTR after pediatric surgery.

METHODS

Cohort study of 200,554 patients within the National Surgical Quality Improvement Program-Pediatric database (2012-2016) who underwent a high (≥ 1%) or low (< 1%) mortality risk inpatient surgical procedures. Patients were stratified based on number of postoperative complications (0, 1, 2, or ≥3) and further categorized as having undergone either a low- or high-risk procedure. The association between the number of postoperative complications and FTR was evaluated with multivariable logistic regression.

RESULTS

Among patients who underwent a low- (89.4%) or high-risk (10.6%) procedures, 14.0% and 12.5% had at least 1 postoperative complication, respectively. FTR rates after low- and high-risk procedures demonstrated step-wise increases as the number of complications accrued (eg, low-risk- 9.2% in patients with ≥3 complications; high-risk-36.9% in patients with ≥ 3 complications). Relative to patients who had no complications, there was a dose-response relationship between mortality and the number of complications after low-risk [1 complication - odds ratio (OR) 3.34 (95% CI 2.62-4.27); 2 - OR 10.15 (95% CI 7.40-13.92); ≥3-27.48 (95% CI 19.06-39.62)] and high-risk operations [1 - OR 3.29 (2.61-4.16); 2-7.24 (5.14-10.19); ≥3-20.73 (12.62-34.04)].

CONCLUSIONS

There is a dose-response relationship between the number of postoperative complications after inpatient surgery and FTR, ever after common, "minor" surgical procedures. These findings suggest FTR may be a potential quality measure for pediatric surgical care.

Association of prematurity with complications and failure to rescue in neonatal surgery

BACKGROUND

The majority of failure to rescue (FTR), or death after a postoperative complication, in pediatric surgery occurs among infants and neonates. The purpose of this study is to evaluate the association between gestational age (GA) and FTR in infants and neonates.

METHODS

National cohort study of 46,452 patients < 1 year old within the National Surgical Quality Improvement Program-Pediatric database who underwent inpatient surgery. Patients were categorized as preterm neonates, term neonates, or infants. Neonates were stratified based on GA. Surgical procedures were classified as low- (< 1% mortality) or high-risk (≥ 1%). Multivariable logistic regression and cubic splines were used to evaluate the association between GA and FTR.

RESULTS

Preterm neonates had the highest FTR (28%) rates. Among neonates, FTR increased with decreasing GA (≥ 37 weeks, 12%; 33-36 weeks, 15%; 29-32 weeks, 30%; 25-28 weeks 41%; ≤ 24 weeks, 57%). For both low- and high-risk procedures, FTR significantly (trend test, p < 0.01) increased with decreasing GA. When stratifying preterm neonates by GA, all GAs ≤ 28 weeks were associated with significantly higher odds of FTR for low- (OR 2.47, 95% CI [1.38-4.41]) and high-risk (OR 2.27, 95% CI [1.33-3.87]) procedures. A lone inflection point for FTR was identified at 31-32 weeks with cubic spline analysis.

CONCLUSIONS

The dose-dependent relationship between decreasing GA and FTR as well as the FTR inflection point noted at GA 31-32 weeks can be used by stakeholders in designing quality improvement initiatives and directing perioperative care.

Use of failure-to-rescue after emergency surgery as a dynamic indicator of hospital resilience during the COVID-19 pandemic. A multicenter retrospective propensity score-matched cohort study

Background

Surgical failure-to-rescue (FTR, death rate following complications) is a reliable cross-sectional quality of care marker, but has not been evaluated dynamically. We aimed to study changes in FTR following emergency surgery during the COVID-19 pandemic.

Material and methods

Matched cohort study including all COVID-19-non-infected adult patients undergoing emergency general surgery in 25 Spanish hospitals during COVID-19 pandemic peak (March–April 2020), non-peak (May–June 2020), and 2019 control periods. A propensity score-matched comparative analysis was conducted using a logistic regression model, in which period was regressed on observed baseline characteristics. Subsequently, a mixed effects logistic regression model was constructed for each variable of interest. Main variable was FTR. Secondary variables were post-operative complications, readmissions, reinterventions, and length of stay.

Results

5003 patients were included (948, 1108, and 2947 in the pandemic peak, non-peak, and control periods), with comparable clinical characteristics, prognostic scores, complications, reintervention, rehospitalization rates, and length of stay across periods. FTR was greater during the pandemic peak than during non-peak and pre-pandemic periods (22.5% vs. 17.2% and 12.7%), being this difference confirmed in adjusted analysis (odds ratio [OR] 2.13, 95% confidence interval [95% CI] 1.27–3.66). There was sensible inter-hospital variability in FTR changes during the pandemic peak (median FTR change +8.77%, IQR 0–29.17%) not observed during the pandemic non-peak period (median FTR change 0%, IQR -6.01−6.72%). Greater FTR increase was associated with higher COVID-19 incidence (OR 2.31, 95% CI 1.31–4.16) and some hospital characteristics, including tertiary level (OR 3.07, 95% CI 1.27–8.00), medium-volume (OR 2.79, 95% CI 1.14–7.34), and high basal-adjusted complication risk (OR 2.21, 95% CI 1.07–4.72).

Conclusion

FTR following emergency surgery experienced a heterogeneous increase during different periods of the COVID-19 pandemic, suggesting it to behave as an indicator of hospital resilience. FTR monitoring could facilitate identification of centres in special needs during ongoing health care challenges.

Impact of surgeon and hospital factors on length of stay after colorectal surgery systematic review

Background

Although length of stay (LOS) after colorectal surgery (CRS) is associated with worse patient and system level outcomes, the impact of surgeon and hospital-level factors on LOS after CRS has not been well investigated. The aim of this study was to synthesize the evidence for the impact of surgeon and hospital-level factors on LOS after CRS.

Methods

A comprehensive database search was conducted using terms related to LOS and CRS. Studies were included if they reported the effect of surgeon or hospital factors on LOS after elective CRS. The evidence for the effect of each surgeon and hospital factor on LOS was synthesized using vote counting by direction of effect, taking risk of bias into consideration.

Results

A total of 13 946 unique titles and abstracts were screened, and 69 studies met the inclusion criteria. All studies were retrospective and assessed a total of eight factors. Surgeon factors such as increasing surgeon volume, colorectal surgical specialty, and progression along a learning curve were significantly associated with decreased LOS (effect seen in 87.5 per cent, 100 per cent, and 93.3 per cent of studies respectively). In contrast, hospital factors such as hospital volume and teaching hospital status were not significantly associated with LOS.

Conclusion

Provider-related factors were found to be significantly associated with LOS after elective CRS. In particular, surgeon-related factors related to experience specifically impacted LOS, whereas hospital-related factors did not. Understanding the mechanisms underlying these relationships may allow for tailoring of interventions to reduce LOS.

Association between index complication and outcomes after inpatient pediatric surgery

PURPOSE

A cascade of complications is believed to be the primary mechanism underlying failure to rescue (FTR), or death of a patient after a postoperative complication. It is unknown whether specific types of index complications are associated with the incidence of secondary complications and FTR after pediatric surgery.

METHODS

National cohort study of patients within the National Surgical Quality Improvement Program-Pediatric database who underwent inpatient surgery (2012-2019). Index complications were grouped into nine categories (cardiovascular, venous thromboembolism, pulmonary, bleeding/transfusion, renal, central nervous system, wound, infectious, or minor [defined as having an associated mortality rate <1%]). The association between the type of index complication with FTR, secondary complications, reoperation, unplanned readmission, and postoperative length of stay was evaluated with multivariable logistic regression and generalized linear modeling.

RESULTS

Among 425,386 patients, 15.5% had at least one complication, 16.6% had one or more secondary complications, 13.9% reoperation, 14.5% readmission, and 2.4% FTR.  Secondary complication (10.8-59.7%) and FTR (0.3-31.1%) rates varied by type of index complication. Relative to patients who had an index minor complication, those with an index infectious complication were most likely to have secondary complication (Odds Ratio [OR] 10.3, 95% CI [9.36-11.4]). Index CV complications were most strongly associated with FTR (OR 30.7 [24.0-39.4]). Index wound complications had the greatest association with reoperation (OR 21.9 [20.5-23.4]) and readmission (OR 18.7 [17.6-19.9]). Index pulmonary complications had the strongest association with length of stay (coefficient 9.39 [8.95-9.83]).

CONCLUSIONS

Different types of index complications are associated with different perioperative outcomes. These data can help identify patients potentially at risk for suboptimal outcomes and can inform pediatric quality improvement interventions.

Guidelines for Perioperative Care in Elective Abdominal and Pelvic Surgery at Primary and Secondary Hospitals in Low-Middle-Income Countries (LMIC's): Enhanced Recovery After Surgery (ERAS) Society Recommendation

BACKGROUND

This is the first Enhanced Recovery After Surgery (ERAS®) Society guideline for primary and secondary hospitals in low-middle-income countries (LMIC's) for elective abdominal and gynecologic care.

METHODS

The ERAS LMIC Guidelines group was established by the ERAS® Society in collaboration with different representatives of perioperative care from LMIC's. The group consisted of seven members from the ERAS® Society and eight members from LMIC's. An updated systematic literature search and evaluation of evidence from previous ERAS® guidelines was performed by the leading authors of the Colorectal (2018) and Gynecologic (2019) surgery guidelines (Gustafsson et al in World J Surg 43:6592-695, Nelson et al in Int J Gynecol Cancer 29(4):651-668). Meta-analyses randomized controlled trials (RCTs), prospective and retrospective cohort studies from both HIC's and LMIC's were considered for each perioperative item. The members in the LMIC group then applied the current evidence and adapted the recommendations for each intervention as well as identifying possible new items relevant to LMIC's. The Grading of Recommendations, Assessment, Development and Evaluation system (GRADE) methodology was used to determine the quality of the published evidence. The strength of the recommendations was based on importance of the problem, quality of evidence, balance between desirable and undesirable effects, acceptability to key stakeholders, cost of implementation and specifically the feasibility of implementing in LMIC's and determined through discussions and consensus.

RESULTS

In addition to previously described ERAS® Society interventions, the following items were included, revised or discussed: the Surgical Safety Checklist (SSC), preoperative routine human immunodeficiency virus (HIV) testing in countries with a high prevalence of HIV/AIDS (CD4 and viral load for those patients that are HIV positive), delirium screening and prevention, COVID 19 screening, VTE prophylaxis, immuno-nutrition, prehabilitation, minimally invasive surgery (MIS) and a standardized postoperative monitoring guideline.

CONCLUSIONS

These guidelines are seen as a starting point to address the urgent need to improve perioperative care and to effect data-driven, evidence-based care in LMIC's.
