Chronologic Age, Independent of Frailty, is the Strongest Predictor of Failure-to-Rescue After Surgery for Gastrointestinal Malignancies.

BACKGROUND: Prior studies of older cancer patients undergoing large operations have reported similar rates of complications to the general population but higher rates of mortality, suggesting higher rates of failure-to-rescue (FTR) with advanced age. Whether age is a marker for frailty, or an independent predictor of FTR, is not clear. METHODS: The ACS-NSQIP database was queried from 2015-19 for patients undergoing surgery for gastrointestinal (GI) malignancy. Patients were divided into age-stratified cohorts: C1 (18-55), C2 (56-65), C3 (66-75), C4 (76-89). Adjusted odds ratios (aOR) were computed to assess the relationship of the FTR rate and age, while controlling for potential confounders. A second analysis was specified with all covariates converted to Z-scores, which generated scaled adjusted odds ratios (saOR) to determine the strongest predictor of FTR. RESULTS: Multivariable analysis suggests that age is an independent predictor of FTR: C2:C1 aOR = 1.87 (p < 0.001); C3:C1 aOR = 3.33 (p < 0.001); C4:C1 aOR = 5.71 (p < 0.001). The scaled analysis demonstrated that age is the strongest predictor of FTR (saOR = 1.92, p < 0.001); a one standard deviation increase in age was associated with a 92% increased odds of FTR. The saOR for frailty (1.18, p < 0.001) and for number of comorbidities (1.10, p = 0.005) also were statistically significant. CONCLUSIONS: Chronologic age was independently associated with increased FTR after surgery for GI malignancy and was the strongest predictor of FTR. These results suggest that chronologic age must be carefully considered when evaluating the fitness of a patient for GI cancer surgery.

Failure to Rescue in Major Abdominal Surgery: A Regional Australian Experience.

BACKGROUND: Failure to rescue (FTR) is increasingly recognised as a measure of the quality care provided by a health service in recognising and responding to patient deterioration. We report the association between a patient's pre-operative status and FTR following major abdominal surgery. METHODS: A retrospective chart review was conducted on patients who underwent major abdominal surgery and who suffered Clavien-Dindo (CDC) III-V complications at the University Hospital Geelong between 2012 and 2019. For each patient suffering a major complication, pre-operative risk factors including demographics, comorbidities (Charlson Comorbidity Index (CCI)), American Society of Anaesthesiology (ASA) Score and biochemistry were compared for patients who survived and patients who died. Statistical analysis utilised logistic regression with results reported as odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: There were 2579 patients who underwent major abdominal surgery, of whom 374 (14.5%) suffered CDC III-V complications. Eighty-eight patients subsequently died from their complication representing a 23.5% FTR and an overall operative mortality of 3.4%. Pre-operative risk factors for FTR included ASA score ≥ 3, CCI ≥ 3 and pre-operative serum albumin of < 35 g/L. Operative risk factors included emergency surgery, cancer surgery, greater than 500 ml intraoperative blood loss and need for ICU admission. Patients who suffered end-organ failure were more likely to die from their complication. CONCLUSION: Identification of patients at high risk of FTR should they develop a complication would inform shared decision-making, highlight the need for optimisation prior to surgery, or in some cases, result in surgery not being undertaken.

Perioperative predictive factors of failure to rescue following highly advanced hepatobiliary-pancreatic surgery: a single-institution retrospective study.

BACKGROUND: Failure to rescue (FTR), defined as a postoperative complication leading to death, is a recently described outcome metric used to evaluate treatment quality. However, the predictive factors for FTR, particularly following highly advanced hepatobiliary-pancreatic surgery (HBPS), have not been adequately investigated. This study aimed to identify perioperative predictive factors for FTR following highly advanced HBPS. METHODS: This single-institution retrospective study involved 177 patients at Gifu University Hospital, Japan, who developed severe postoperative complications (Clavien-Dindo classification grades ≥ III) between 2010 and 2022 following highly advanced HBPS. Univariate analysis was used to identify pre-, intra-, and postoperative risks of FTR. RESULTS: Nine postoperative mortalities occurred during the study period (overall mortality rate, 1.3% [9/686]; FTR rate, 5.1% [9/177]). Univariate analysis indicated that comorbid liver disease, intraoperative blood loss, intraoperative blood transfusion, postoperative liver failure, postoperative respiratory failure, and postoperative bleeding significantly correlated with FTR. CONCLUSIONS: FTR was found to be associated with perioperative factors. Well-coordinated surgical procedures to avoid intra- and postoperative bleeding and unnecessary blood transfusions, as well as postoperative team management with attention to the occurrence of organ failure, may decrease FTR rates.

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.

Failure to rescue in emergency general surgery in Canada.

BACKGROUND: The risk of death after a postoperative complication - known as failure to rescue (FTR) - has been proposed to be superior to traditional benchmarking outcomes, such as complication and mortality rates, as a measure of system quality. The purpose of this study was to identify the current FTR rate in emergency general surgery (EGS) centres across Canada. We hypothesized that substantial variability exists in FTR rates across centres. METHODS: In this multicentre retrospective cohort study, we performed a secondary analysis of data from a previous study designed to evaluate operative intervention for nonappendiceal, nonbiliary disease by 6 EGS services across Canada (1 in British Columbia, 1 in Alberta, 3 in Ontario and 1 in Nova Scotia). Patients underwent surgery between Jan. 1 and Dec. 31, 2014. We conducted univariate analyses to compare patients with and without complications. We performed a sensitivity analysis examining the mortality rate after serious complications (Clavien-Dindo score 3 or 4) that required a surgical intervention or specialized care (e.g., admission to intensive care unit). RESULTS: A total of 2595 patients were included in the study cohort. Of the 206 patients who died within 30 days, 145 (70.4%) experienced a complication before their death. Overall, the mortality rate after any surgical complication (i.e., FTR) was 16.0%. Ranking of sites by the traditional outcomes of complication and mortality rates differed from the ranking when FTR rate was included in the assessment. CONCLUSION: There was variability in FTR rates across EGS services in Canada, which suggests that there is opportunity for ongoing quality-improvement efforts. This study provides FTR benchmarking data for Canadian EGS services.

Pancreatoduodenectomy in obese patients: surgery for nonmalignant tumors might be deferred.

BACKGROUND: Obesity has traditionally been considered a cause of increased surgical complexity and poor outcomes following pancreatoduodenectomy (PD). This study aimed at evaluating the role of obesity in terms of mortality and failure to rescue (FTR), with a particular focus on nonmalignant tumors. METHODS: All patients undergoing elective PD over 10 consecutive years were analyzed. Patients were stratified according to their BMI and categorized into two groups. Predictors of mortality and FTR were assessed through logistic regression. RESULTS: Out of 1865 patients included, 151 were obese (8.1%). Overall mortality and FTR were 3.1% and 14.1%, respectively. In obese patients, mortality was 6.0% and FTR 26.5%, significantly higher compared to nonobese (p < 0.05). In the multivariable analysis, obesity, age > 70 years, and ASA-PS score were independent predictors of mortality and FTR. Postoperative pancreatic fistula (35.8% vs. 25.8%), postpancreatectomy acute pancreatitis (24.5% vs. 12.5%), and chyle leak (6.0% vs. 3.2%) were more frequent among obese patients. In the subgroup of patients with nonmalignant tumors (n = 443), obesity was the only independent predictor of FTR. CONCLUSION: PD performed in obese patients was associated with higher surgical morbidity and mortality. When dealing with nonmalignant tumors, deferring surgery in obese patients should be strongly considered.

Failure to Rescue After Pancreatoduodenectomy: A Transatlantic Analysis.

OBJECTIVE: This analysis aimed to compare failure to rescue (FTR) after pancreatoduodenectomy across the Atlantic. SUMMARY BACKGROUND DATA: FTR, or mortality after development of a major complication, is a quality metric originally created to compare hospital results. FTR has been studied in North American and Northern European patients undergoing pancreatoduodenectomy (PD). However, a direct comparison of FTR after PD between North America and Northern Europe has not been performed. METHODS: Patients who underwent PD in North America, the Netherlands, Sweden and Germany (GAPASURG dataset) were identified from their respective registries (2014-17). Patients who developed a major complication defined as Clavien-Dindo ≥3 or developed a grade B/C postoperative pancreatic fistula (POPF) were included. Preoperative, intraoperative, and postoperative variables were compared between patients with and without FTR. Variables significant on univariable analysis were entered into a logistic regression for FTR. RESULTS: Major complications occurred in 6188 of 22,983 patients (26.9%) after PD, and 504 (8.1%) patients had FTR. North American and Northern European patients with complications differed, and rates of FTR were lower in North America (5.4% vs 12%, P < 0.001). Fourteen factors from univariable analysis contributing to differences in patients who developed FTR were included in a logistic regression. On multivariable analysis, factors independently associated with FTR were age, American Society of Anesthesiology ≥3, Northern Europe, POPF, organ failure, life-threatening complication, nonradiologic intervention, and reoperation. CONCLUSIONS: Older patients with severe systemic diseases are more difficult to rescue. Failure to rescue is more common in Northern Europe than North America. In stable patients, management of complications by interventional radiology is preferred over reoperation.

Association Between Hospital Volume and Failure to Rescue After Open or Endovascular Repair of Intact Abdominal Aortic Aneurysms in the VASCUNET and International Consortium of Vascular Registries.

OBJECTIVE: To investigate the association between hospital volume and failure to rescue (FtR), after open repair (OAR), and endovascular repair (EVAR) of intact abdominal aortic aneurysms (AAA) among centers participating in the VASCUNET and International Consortium of Vascular Registries. SUMMARY OF BACKGROUND DATA: FtR (ie, in-hospital death following major complications) is a composite end-point representing the inability to treat complications effectively and prevent death. METHODS: Using data from 8 vascular registries, complication and mortality rates after intact AAA repair were examined (n = 60,273; EVAR-43,668; OAR-16,605). A restricted analysis using pooled data from 4 countries (Australia, Hungary, New Zealand, and USA) reporting data on all postoperative complications (bleeding, stroke, cardiac, respiratory, renal, colonic ischemia) was performed to identify risk-adjusted association between hospital volume and FtR. RESULTS: The most frequently reported complications were cardiac (EVAR-3.0%, OAR-8.9%) and respiratory (EVAR-1.0%, OAR-5.7%). In adjusted analysis, 4.3% of EVARs and 18.5% of OARs had at least 1 complication. The overall FtR rate was 10.3% after EVAR and 15.7% after OAR. Subjects treated in the highest volume centers (Q4) had 46% and 80% lower odds of FtR after EVAR (OR = 0.54; 95% CI = 0.34-0.87; P = 0.04) and OAR (OR = 0.22; 95% CI = 0.11-0.44; P < 0.001) when compared to lowest volume centers (Q1), respectively. Colonic ischemia had the highest risk of FtR for both procedures (adjusted predicted risks, EVAR: 27%, 95% CI 14%-45%; OAR: 30%, 95% CI 17%-46%). CONCLUSIONS: In this multi-national dataset, FtR rate after intact AAA repair with EVAR and OAR is significantly associated with hospital volume. Hospitals in the top volume quartiles achieve the lowest mortality after a complication has occurred.

Association between hospital volume and failure-to-rescue for open repairs of juxtarenal aneurysms.

BACKGROUND: A nationwide variation in mortality stratified by hospital volume exists after open repair of complex abdominal aortic aneurysms (AAAs). In the present study, we assessed whether the rates of postoperative complications or failure-to-rescue (defined as death after a major postoperative complication) would better explain the lower mortality rates among higher volume hospitals. METHODS: Using the 2004 to 2018 Vascular Quality Initiative database, we identified all patients who had undergone open repair of elective or symptomatic AAAs, in which the proximal clamp sites were at least above one renal artery. We divided the patients into hospital quintiles according to the annual hospital volume and compared the risk-adjusted outcomes. Multivariable logistic regression, adjusted for patient characteristics, operative factors, and hospital volume, was used to evaluate three outcomes: 30-day mortality, overall complications, and failure-to-rescue. RESULTS: We identified 3566 patients who had undergone open repair of elective or symptomatic complex AAAs (median age, 71 years; 29% women; 4.1% black; 48% Medicare insurance). The unadjusted rates of 30-day postoperative mortality, overall complications, and failure-to-rescue were 5.0%, 44%, and 10%, respectively. Common complications included renal dysfunction (25%), cardiac dysrhythmia (14%), and pneumonia (14%), with the specific failure-to-rescue rate ranging from 12% to 22%. On adjusted analysis, the risk-adjusted mortality rate was 2.5 times greater for the lower volume hospitals relative to the higher volume hospitals (7.4% vs 3.0%; P < .01). Although the risk-adjusted complication rates were similar between these hospital groups (30% vs 27%; P = .06), the failure-to-rescue rate was 2.3 times greater for the lower volume hospitals relative to the higher volume hospitals (6.3% vs 2.7%; P = .02). CONCLUSIONS: Higher volume hospitals had lower mortality rates after open repair of complex AAAs because they were better at the "rescue" of patients after the occurrence of postoperative complications. Both an understanding of the clinical mechanisms underlying this association and the regionalization of open repair might improve patient outcomes.

The variable impact of aneurysm size on outcomes after open abdominal aortic aneurysm repairs.

OBJECTIVE: Previous studies evaluating the association between abdominal aortic aneurysm (AAA) size with postoperative outcomes after open repairs seldom accounted for renal or visceral artery involvement, proximal clamp site, intraoperative renal ischemia time, and hospital volume. This study examined the association between aneurysm size with outcomes after open repairs. METHODS: We identified patients who underwent open repairs of infrarenal versus juxtarenal nonruptured AAAs, defined by proximal clamp site, in the 2004-2019 Vascular Quality Initiative. Outcomes included 30-day mortality, postoperative complications, failure to rescue, and 1-year mortality. Multivariable logistic regressions adjusted for patient characteristics, operative factors, hospital volume, and hospital clustering. RESULTS: We identified 8011 patients (54% infrarenal, 46% juxtarenal). The median aneurysm size did not differ between infrarenal versus juxtarenal aneurysms (5.7 cm vs 5.9 cm; P = .12). For infrarenal aneurysms, every 1-cm increase in size increase the adjusted odds ratio (OR) or hazard ratio (HR) of 30-day mortality by 18% (OR, 1.18; 95% CI, 1.06-1.31), failure to rescue by 20% (OR, 1.20; 95% CI, 1.06-1.34), 1-year mortality by 18% (HR, 1.18; 95% CI, 1.10-1.26), but not complications (OR, 1.03; 95% CI, 0.98-1.07). For juxtarenal aneurysm, larger aneurysm sizes were not associated with any outcome. Proximal clamp site, ischemia time, and volume were associated with outcomes. CONCLUSIONS: The association between AAA size and outcomes matters less with renal and visceral artery aneurysmal involvement, having important implications for surgical decision-making, operative planning, and patient counseling.

The Impact of Socially Stigmatized Preexisting Conditions on Outcomes After Injury.

BACKGROUND: Socially stigmatized preexisting conditions (SSPECs), including alcohol use disorder (AUD), drug use disorder (DUD), and major psychiatric illness, may lead to provider minimization of patient symptoms and have been associated with negative outcomes. However, the impact of SSPECs on failure to rescue (FTR) has not been evaluated. We hypothesized that SSPEC patients would have increased probability of complications, mortality, and FTR. MATERIALS AND METHODS: We performed a retrospective analysis of the 2015 National Trauma Data Bank, including patients aged ≥18 y and excluding burn victims, patients with Injury Severity Score <9, and non-SSPEC patients with drug or alcohol withdrawal. We defined SSPECs using the National Trauma Data Bank's comorbidity recording codes for AUD, DUD, and major psychiatric illnesses. We built multivariable logistic regression models to determine the relationships between SSPECs and complications, mortality, and FTR. RESULTS: We included 365,801 patients (62% male, 76% White, median age 56 y [interquartile range 35-74], median Injury Severity Score 10 [interquartile range 9-17]). After adjusting for patient and injury characteristics, SSPEC patients were more likely to have complications (odds ratio [OR] 1.75, 95% confidence interval [CI] 1.70-1.79), less likely to die (OR 0.43, CI 0.38-0.48), and less likely to have FTR (OR 0.34, CI 0.26-0.43). SSPEC patients had a significantly higher complication rate (12.4% versus 7.2%; P < 0.001). After excluding drug or alcohol withdrawal, the complication rate remained significantly higher for SSPEC patients (9.3% versus 7.2%; P < 0.001). CONCLUSIONS: Although SSPEC patients have lower odds of mortality and FTR, they are at higher probability of complications after injury. Further investigation into the causality behind the higher complications despite lower mortality and FTR is warranted.

Increasing Frailty in Geriatric Emergency General Surgery: A Cause for Concern.

BACKGROUND: Emergency general surgery (EGS) presents a challenge for frail, geriatric individuals who often have extensive comorbidities affecting postoperative recovery. Previous studies have shown an association between increasing frailty and adverse outcomes following elective and EGS; no study has explored the same for the geriatric patient population using the modified 5-item frailty index (mFI-5) score. MATERIALS AND METHODS: A retrospective cohort study was performed using the 2012-2017 American College of Surgeons - National Surgical Quality Improvement Program database to identify geriatric patients (≥65 years) undergoing EGS procedures within 48 h of admission. The previously validated mFI-5 score was used to assess preoperative frailty. The study cohort was divided into four groups: mFI-5 = 0, mFI-5 = 1, mFI-5 = 2, and mFI-5 ≥ 3; the impact of increasing mFI-5 score on failure-to-rescue (FTR), 30-day complications, readmissions, reoperations, and mortality was assessed. RESULTS: A total of 47,216 patients were included: 27.4% with mFI-5 = 0, 45% with mFI-5 = 1, 22.1% with mFI-5 = 2, and 5.5% with mFI-5 ≥ 3. Following multivariate analyses, increasing mFI-5 score was associated with higher odds of FTR (mFI-5 = 1: odds ratio (OR) 1.48, p=0.003; mFI-5 = 2: OR 2.66, p <0.001; mFI-5 ≥ 3: OR 3.97, p <0.001), 30-day complications (mFI-5 = 1: OR 1.46, p <0.001; mFI-5 = 2: OR 2.48, p <0.001; mFI-5≥3: OR 5.01, p <0.001), reoperation (mFI-5 = 1: OR 1.42, p = 0.020; mFI-5 = 2: OR 1.70, p = 0.021; mFI-5 ≥ 3: OR 2.18, p = 0.009) and all-cause mortality (mFI-5 = 1: OR 1.49, p=0.001; mFI-5 = 2: OR 2.67, p <0.001; mFI-5 ≥ 3: 3.96, p <0.001). CONCLUSIONS: Increasing frailty in geriatric EGS patients is associated with significantly higher rates of FTR, 30-day complications, reoperations, and all-cause mortality. The mFI-5 score can be used to assess frailty and better anticipate the postoperative course of vulnerable geriatric patients.

Hospital Safety-Net Burden Is Associated With Increased Inpatient Mortality and Perioperative Complications After Colectomy.

BACKGROUND: Colectomies are common yet costly, with high surgical-site infection rates. Safety-net hospitals (SNHs) carry a large proportion of uninsured or Medicaid-insured patients, which has been associated with poorer surgical outcomes. Few studies have examined the effect of safety-net burden (SNB) status on colectomy outcomes. We aimed to quantify the independent effects of hospital SNB and surgical site infection (SSI) status on colectomy outcomes, as well as the interaction effect between SSIs and SNB. METHODS: We used the Healthcare Cost and Utilization Project's State Inpatient Databases for California, Florida, New York, Maryland, and Kentucky. We included 459,568 colectomies (2009 to 2014) for analysis, excluding patients age <18 y and rectal cases. The primary and secondary outcomes were inpatient mortality and complications, respectively. RESULTS: Adjusting for patient, procedure, and hospital factors, colectomy patients were more likely to die in-hospital at high-burden SNHs (adjusted OR [aOR]: 1.38, 95% confidence interval [CI]: 1.25-1.51, P < 0.001), compared with low SNB hospitals and to experience perioperative complications (aOR: 1.12, 95% CI: 1.04-1.20, P < 0.01). Colectomy patients with SSIs also had greater odds of in-hospital mortality (aOR: 1.92, 95% CI: 1.83-2.02, P < 0.001) and complications (aOR: 3.65, 95% CI: 3.55-3.75, P < 0.001) compared with those without infections. Patients treated at SNHs who developed a SSI were even more likely to have an additional perioperative complication (aOR: 4.33, 95% CI: 3.98-4.71, P < 0.001). CONCLUSIONS: Our study demonstrated that colectomy patients at SNHs have poorer outcomes, and for patients with SSIs, this disparity was even more pronounced in the likelihood for a complication. SNB should be recognized as a significant hospital-level factor affecting colectomy outcomes, with SSIs as an important quality metric.

Appendicitis Mortality in a Resource-Limited Setting: Issues of Access and Failure to Rescue.

BACKGROUND: Appendicitis is one of the most common emergency surgery conditions worldwide, and the incidence is increasing in low- and middle-income countries. Disparities in access to care can lead to disproportionate morbidity and mortality in resource-limited settings; however, outcomes following an appendectomy in low- and middle-income countries remain poorly described. Therefore, we aimed to describe the characteristics and outcomes of patients with appendicitis presenting to a tertiary care center in Malawi. METHODS: We conducted a retrospective analysis of the Kamuzu Central Hospital (KCH) Acute Care Surgery database from 2013 to 2020. We included all patients ≥13 years with a postoperative diagnosis of acute appendicitis. We performed bivariate analysis by mortality, followed by a modified Poisson regression analysis to determine predictors of mortality. RESULTS: We treated 214 adults at KCH for acute appendicitis. The majority experienced prehospital delays to care, presenting at least 1 week from symptom onset (n = 99, 46.3%). Twenty (9.4%) patients had appendiceal perforation. Mortality was 5.6%. The presence of a postoperative complication the only statistically significant predictor of mortality (RR 5.1 [CI 1.13-23.03], P = 0.04) when adjusting for age, shock, transferring, and time to presentation. CONCLUSIONS: Delay to intervention due to inadequate access to care predisposes our population for worse postoperative outcomes. The increased risk of mortality associated with resultant surgical complications suggests that failure to rescue is a significant contributor to appendicitis-related deaths at KCH. Improvement in barriers to diagnosis and management of complications is necessary to reduce further preventable deaths from this disease.

Hospital volume following major surgery for gastric cancer determines in-hospital mortality rate and failure to rescue: a nation-wide study based on German billing data (2009-2017).

BACKGROUND: For many cancer resections, a hospital volume-outcome relationship exists. The data regarding gastric cancer resection-especially in the western hemisphere-are ambiguous. This study analyzes the impact of gastric cancer surgery caseload per hospital on postoperative mortality and failure to rescue in Germany. METHODS: All patients diagnosed with gastric cancer from 2009 to 2017 who underwent gastric resection were identified from nation-wide administrative data. Hospitals were grouped into five equal caseload quintiles (I-V in ascending caseload order). Postoperative deaths and failure to rescue were determined. RESULTS: Forty-six thousand one hundred eighty-seven patients were identified. There was a significant shift from partial resections in low-volume hospitals to more extended resections in high-volume centers. The overall in-house mortality rate was 6.2%. The crude in-hospital mortality rate ranged from 7.9% in quintile I to 4.4% in quintile V, with a significant trend between volume categories (p < 0.001). In the multivariable logistic regression analysis, quintile V hospitals (average of 29 interventions/year) had a risk-adjusted odds ratio of 0.50 (95% CI 0.39-0.65), compared to the baseline in-house mortality rate in quintile I (on average 1.5 interventions/year) (p < 0.001). In an analysis only evaluating hospitals with more than 30 resections per year mortality dropped below 4%. The overall postoperative complication rate was comparable between different volume quintiles, but failure to rescue (FtR) decreased significantly with increasing caseload. CONCLUSION: Patients who had gastric cancer surgery in hospitals with higher volume had better outcomes and a reduced failure to rescue rates for severe complications.

Racial Disparities in Failure to Rescue Following Unplanned Reoperation in Pediatric Surgery.

BACKGROUND: Failure to rescue (FTR) and unplanned reoperation following an index surgical procedure are key indicators of the quality of surgical care. Given that differences in unplanned reoperation and FTR rates among racial groups may contribute to persistent disparities in postsurgical outcomes, we sought to determine whether racial differences exist in the risk of FTR among children who required unplanned reoperation following inpatient surgical procedures. METHODS: We used the National Surgical Quality Improvement database (2012-2017) to assemble a cohort of children (<18 years), who underwent inpatient surgery and subsequently returned to the operating room within 30 days of the index surgery. We used logistic regression models to estimate the odds ratio (OR) and 95% confidence interval (CI) of FTR, comparing African American (AA) to White children. We estimated the risk-adjusted odds ratio (aOR) for FTR by controlling the analyses for demographic characteristics, surgical profile, and preoperative comorbidities. We further evaluated the racial differences in FTR by stratifying the analyses by the timing of unplanned reoperation. RESULTS: Of 276,917 children who underwent various inpatient surgical procedures, 10,425 (3.8%) required an unplanned reoperation, of whom 2016 (19.3%) were AA and 8409 (80.7%) were White. Being AA relative to being White was associated with a 2-fold increase in the odds of FTR (aOR: 2.03; 95% CI, 1.5-2.74; P < .001). Among children requiring early unplanned reoperation, AAs were 2.38 times more likely to die compared to their White peers (8.9% vs 3.4%; aOR: 2.38; 95% CI, 1.54-3.66; P < .001). In children with intermediate timing of return to the operating room, the risk of FTR was 80% greater for AA children compared to their White peers (2.2% vs 1.1%; aOR: 1.80; 95% CI, 1.07-3.02; P = .026). Typically, AA children die within 5 days (interquartile range [IQR]: 1-16) of reoperation while their White counterparts die within 9 days following reoperation (IQR: 2-26). CONCLUSIONS: Among children requiring unplanned reoperation, AA patients were more likely to die than their White peers. This racial difference in FTR rate was most noticeable among children requiring early unplanned reoperation. Time to mortality following unplanned reoperation was shorter for AA than for White children. Race appears to be an important determinant of FTR following unplanned reoperation in children and it should be considered when designing interventions to optimize unplanned reoperation outcomes.

The problem of postoperative respiratory depression.

WHAT IS KNOWN AND OBJECTIVE: Postsurgical recovery is influenced by multiple pre-, intra- and perioperative pharmacotherapeutic interventions, including the administration of medications that can induce respiratory depression postoperatively. We present a succinct overview of the topic, including the nature and magnitude of the problem, contributing factors, current limited options, and potential novel therapeutic approach. COMMENT: Pre-, intra- and perioperative medications are commonly administered for anxiety, anaesthesia, muscle relaxation and pain relief among other reasons. Several of the medications alone or in joint-action can be additive or synergistic producing respiratory depression. Given the large number of surgical procedures that are performed each year, even a small percentage of postoperative respiratory complications translates into a large number of affected patients. WHAT IS NEW AND CONCLUSION: Due to the large number of surgeries performed each year, and the variety of medications used before, during, and after surgery, the occurrence of postoperative respiratory depression is surprisingly common. It is a significant medical problem and burden on hospital resources. There is a need for new strategies to prevent and treat the acute and collateral problems associated with postoperative respiratory depression.

Association of the COVID-19 Pandemic and Low-rescue Suicide Attempts in Patients Visiting the Emergency Department after Attempting Suicide.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic may increase the total number of suicide attempts and the proportion of low-rescue attempts. We investigated the factors affecting low-rescue suicide attempts using the risk-rescue rating scale (RRRS) among patients who visited the emergency department (ED) after attempting suicide before or during the COVID-19 pandemic. METHODS: We retrospectively investigated suicide attempts made by patients who visited our ED from March 2019 to September 2020. Patients were classified into two groups based on whether they attempted suicide before or during the COVID-19 pandemic. Data on demographic variables, psychiatric factors, suicide risk factors and rescue factors were collected and compared. RESULTS: A total of 518 patients were included in the study, 275 (53.1%) of whom attempted suicide during the COVID-19 pandemic. The proportion of patients who made low-rescue suicide attempts differed before and during the COVID-19 pandemic (37.1% vs. 28.8%) (P = 0.046). However, the proportions of patients who made high-risk suicide attempts and high-lethality suicide attempts did not significantly differ between the two periods. The independent risk factors for low-rescue suicide attempts were age and the COVID-19 pandemic (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00-1.03; P = 0.006) (OR, 1.52; 95% CI, 1.03-2.25; P = 0.034). CONCLUSION: The COVID-19 pandemic was associated with low-rescue suicide attempts in patients visiting the ED after attempting suicide. Thus, we need to consider the implementation of measures to prevent low-rescue suicide attempts during similar infectious disease crises.

Failure to rescue in patients with distal pancreatectomy: a nationwide analysis of 10,632 patients.

BACKGROUND: FTR appears as a major cause of postoperative mortality (POM). Hospital volume has an impact on FTR in pancreatic surgery but no study has investigated this relationship more specifically in DP. METHODS: We analysed patients with DP between 2009 and 2018 through a nationwide database. FTR definition was mortality among patients who experiment major complications. The cutoff between high and low volume centers was 20 pancreatectomies per year. RESULTS: Some 10,632 patients underwent DP, 5048 (47.5%) were operated in 602 (95.4%) low volume centers and 5584 (52.5%) in 29 (4.6%) high volume centers. Overall FTR occurred in 11.2% of patients and was significantly reduced in high volume centers compared to low volume centers (10.2% vs 12.5%, p = 0.047). In multivariate analysis, surgery in a high volume center was a protective factor for POM (OR = 0.570, CI95% [0.505-0.643], p < 0.001) and also for FTR (OR = 0.550, CI95% [0.486-0.630], p < 0.001). CONCLUSION: Hospital volume has a positive impact on FTR in DP. Patients with higher risk of FTR are men, with high modified Charlson comorbidity index, malignant conditions and open procedures.

Factors associated with failure to rescue after liver resection and impact on hospital variation: a nationwide population-based study.

BACKGROUND: Failure to rescue (FTR) is defined as postoperative complications leading to mortality. This nationwide study aimed to assess factors associated with FTR and hospital variation in FTR after liver surgery. METHODS: All patients who underwent liver resection between 2014 and 2017 in the Netherlands were included. FTR was defined as in-hospital or 30-day mortality after complications Dindo grade ≥3a. Variables associated with FTR and nationwide hospital variation were assessed using multivariable logistic regression. RESULTS: Of 4961 patients included, 3707 (74.4%) underwent liver resection for colorectal liver metastases, 379 (7.6%) for other metastases, 526 (10.6%) for hepatocellular carcinoma and 349 (7.0%) for biliary cancer. Thirty-day major morbidity was 11.5%. Overall mortality was 2.3%. FTR was 19.1%. Age 65-80 (aOR: 2.86, CI:1.01-12.0, p = 0.049), ASA 3+ (aOR:2.59, CI: 1.66-4.02, p < 0.001), liver cirrhosis (aOR:4.15, CI:1.81-9.22, p < 0.001), biliary cancer (aOR:3.47, CI: 1.73-6.96, p < 0.001), and major resection (aOR:6.46, CI: 3.91-10.9, p < 0.001) were associated with FTR. Postoperative liver failure (aOR: 26.9, CI: 14.6-51.2, p < 0.001), cardiac (aOR: 2.62, CI: 1.27-5.29, p = 0.008) and thromboembolic complications (aOR: 2.49, CI: 1.16-5.22, p = 0.017) were associated with FTR. After case-mix correction, no hospital variation in FTR was observed. CONCLUSION: FTR is influenced by patient demographics, disease and procedural burden. Prevention of postoperative liver failure, cardiac and thromboembolic complications could decrease FTR.
