RESUMO
OBJECTIVE: To establish surgical site infection (SSI) performance benchmarks in pediatric surgery and to develop a prioritization framework for SSI prevention based on procedure-level SSI burden. BACKGROUND: Contemporary epidemiology of SSI rates and event burden in elective pediatric surgery remain poorly characterized. METHODS: Multicenter analysis using sampled SSI data from 90 hospitals participating in NSQIP-Pediatric and procedural volume data from the Pediatric Health Information System (PHIS) database. Procedure-level incisional and organ space SSI (OSI) rates for 17 elective procedure groups were calculated from NSQIP-Pediatric data and estimates of procedure-level SSI burden were extrapolated using procedural volume data. The relative contribution of each procedure to the cumulative sum of SSI events from all procedures was used as a prioritization framework. RESULTS: A total of 11,689 nonemergent procedures were included. The highest incisional SSI rates were associated with gastrostomy closure (4.1%), small bowel procedures (4.0%), and gastrostomy (3.7%), while the highest OSI rates were associated with esophageal atresia/tracheoesophageal fistula repair (8.1%), colorectal procedures (1.8%), and small bowel procedures (1.5%). 66.1% of the cumulative incisional SSI burden from all procedures were attributable to 3 procedure groups (gastrostomy: 27.5%, small bowel: 22.9%, colorectal: 15.7%), and 72.8% of all OSI events were similarly attributable to 3 procedure groups (small bowel: 28.5%, colorectal: 26.0%, esophageal atresia/tracheoesophageal fistula repair: 18.4%). CONCLUSIONS: A small number of procedures account for a disproportionate burden of SSIs in pediatric surgery. The results of this analysis can be used as a prioritization framework for refocusing SSI prevention efforts where they are needed most.

Importance: Despite improvements in perioperative mortality, the incidence of postoperative surgical site infection (SSI) remains high after pancreatoduodenectomy. The effect of broad-spectrum antimicrobial surgical prophylaxis in reducing SSI is poorly understood. Objective: To define the effect of broad-spectrum perioperative antimicrobial prophylaxis on postoperative SSI incidence compared with standard care antibiotics. Design, Setting, and Participants: Pragmatic, open-label, multicenter, randomized phase 3 clinical trial at 26 hospitals across the US and Canada. Participants were enrolled between November 2017 and August 2021, with follow-up through December 2021. Adults undergoing open pancreatoduodenectomy for any indication were eligible. Individuals were excluded if they had allergies to study medications, active infections, chronic steroid use, significant kidney dysfunction, or were pregnant or breastfeeding. Participants were block randomized in a 1:1 ratio and stratified by the presence of a preoperative biliary stent. Participants, investigators, and statisticians analyzing trial data were unblinded to treatment assignment. Intervention: The intervention group received piperacillin-tazobactam (3.375 or 4 g intravenously) as perioperative antimicrobial prophylaxis, while the control group received cefoxitin (2 g intravenously; standard care). Main Outcomes and Measures: The primary outcome was development of postoperative SSI within 30 days. Secondary end points included 30-day mortality, development of clinically relevant postoperative pancreatic fistula, and sepsis. All data were collected as part of the American College of Surgeons National Surgical Quality Improvement Program. Results: The trial was terminated at an interim analysis on the basis of a predefined stopping rule. Of 778 participants (378 in the piperacillin-tazobactam group [median age, 66.8 y; 233 {61.6%} men] and 400 in the cefoxitin group [median age, 68.0 y; 223 {55.8%} men]), the percentage with SSI at 30 days was lower in the perioperative piperacillin-tazobactam vs cefoxitin group (19.8% vs 32.8%; absolute difference, -13.0% [95% CI, -19.1% to -6.9%]; P < .001). Participants treated with piperacillin-tazobactam, vs cefoxitin, had lower rates of postoperative sepsis (4.2% vs 7.5%; difference, -3.3% [95% CI, -6.6% to 0.0%]; P = .02) and clinically relevant postoperative pancreatic fistula (12.7% vs 19.0%; difference, -6.3% [95% CI, -11.4% to -1.2%]; P = .03). Mortality rates at 30 days were 1.3% (5/378) among participants treated with piperacillin-tazobactam and 2.5% (10/400) among those receiving cefoxitin (difference, -1.2% [95% CI, -3.1% to 0.7%]; P = .32). Conclusions and Relevance: In participants undergoing open pancreatoduodenectomy, use of piperacillin-tazobactam as perioperative prophylaxis reduced postoperative SSI, pancreatic fistula, and multiple downstream sequelae of SSI. The findings support the use of piperacillin-tazobactam as standard care for open pancreatoduodenectomy. Trial Registration: ClinicalTrials.gov Identifier: NCT03269994.

BACKGROUND: There has been longstanding uncertainty over whether lower healthcare spending in Canada might be associated with inferior outcomes for hospital-based care. We hypothesized that mortality and surgical complication rates would be higher for patients who underwent four common surgical procedures in Canada as compared to the US. DESIGN, SETTING, AND PARTICIPANTS: We conducted a retrospective cohort study of all adults who underwent hip fracture repair, colectomy, pancreatectomy, or spine surgery in 96 Canadian and 585 US hospitals participating in the American College of Surgeons National Surgical Quality Improvement Project (ACS-NSQIP) between January 1, 2015 and December 31, 2019. We compared patients with respect to demographic characteristics and comorbidity. We then compared unadjusted and adjusted outcomes within 30-days of surgery for patients in Canada and the US including: (1) Mortality; (2) A composite constituting 1-or-more of the following complications (cardiac arrest; myocardial infarction; pneumonia; renal failure/; return to operating room; surgical site infection; sepsis; unplanned intubation). RESULTS: Our hip fracture cohort consisted of 21,166 patients in Canada (22.3%) and 73,817 in the US (77.7%), for colectomy 21,279 patients in Canada (8.9%) and 218,307 (91.1%), for pancreatectomy 873 (7.8%) in Canada and 12,078 (92.2%) in the US, and for spine surgery 14,088 (5.3%) and 252,029 (94.7%). Patient sociodemographics and comorbidity were clinically similar between jurisdictions. In adjusted analyses odds of death was significantly higher in Canada for two procedures (colectomy (OR 1.22; 95% CI 1.044-1.424; P = .012) and pancreatectomy (OR 2.11; 95% CI 1.26-3.56; P = .005)) and similar for hip fracture and spine surgery. Odds of the composite outcome were significantly higher in Canada for all 4 procedures, largely driven by higher risk of cardiac events and post-operative infections. CONCLUSIONS: We found evidence of higher rates of mortality and surgical complications within 30-days of surgery for patients in Canada as compared to the US.

OBJECTIVE: To evaluate local hospital success with enhanced recovery implementation as measured by colorectal surgery process measure (PM) compliance and characterize local environment factors associated with success within a contemporary quality improvement collaborative. SUMMARY BACKGROUND DATA: Enhanced recovery programs (ERP) have proven an effective perioperative quality improvement strategy, but local variation in implementation can hinder patient outcome improvement. METHODS: Individual hospitals participating in a national colorectal ERP quality improvement program were evaluated with quantitative (patient-level process and outcome) and qualitative (survey and structured interviews with hospital teams) data between 2017 and 2020. Hospitals with implementation success were identified: high performers (80% of elective colorectal surgery patients compliant with >6/9 PMs) and high improvers (top quartile of PM adherence improvement over time). Hospital and implementation characteristics were compared with chi-square tests. Trends in average annual outcome change were estimated with logistic and linear regression. RESULTS: Of 207 total hospitals, 62 were characterized as High Performance and 52 as High Improvement. High Performance hospitals were larger, with more annual colorectal surgeries (128 vs 101, P = 0.039). Qualitative assessment revealed fewer barriers of staff buy-in and competing priorities, and more experience with standardized perioperative care in High Performance hospitals. High Improvement hospitals had lower baseline PM adherence (54.1% vs 69.6%, P < 0.001) and less experience with standardized perioperative care (30.8% vs 58.1%, P < 0.001) but were noted to have a positive trend in annual patient outcomes: annual morbidity (Δ-1.14% vs -0.20%, P = 0.035), readmission (Δ-1.85% vs 0.002%, P = 0.037), and prolonged length of stay (Δ-3.94 vs -1.19, P = 0.037) compared to Low Improvement hospitals. CONCLUSIONS: When evaluating a collection of hospitals implementing ERP, only half of hospitals reached consistent High Performance or high improvement. Characteristics of the local environment need further study to understand the barriers to effective implementation in a pragmatic setting.

OBJECTIVES: The aims of this study were to: (1) measure the prevalence of self-reported medical error among general surgery trainees, (2) assess the association between general surgery resident wellness (ie, burnout and poor psychiatric well-being) and self-reported medical error, and (3) examine the association between program-level wellness and objectively measured patient outcomes. SUMMARY OF BACKGROUND DATA: Poor wellness is prevalent among surgical trainees but the impact on medical error and objective patient outcomes (eg, morbidity or mortality) is unclear as existing studies are limited to physician and patient self-report of events and errors, small cohorts, or examine few outcomes. METHODS: A cross-sectional survey was administered immediately following the January 2017 American Board of Surgery In-training Examination to clinically active general surgery residents to assess resident wellness and self-reported error. Postoperative patient outcomes were ascertained using a validated national clinical data registry. Associations were examined using multivariable logistic regression models. RESULTS: Over a 6-month period, 22.5% of residents reported committing a near miss medical error, and 6.9% reported committing a harmful medical error. Residents were more likely to report a harmful medical error if they reported frequent burnout symptoms [odds ratio 2.71 (95% confidence interval 2.16-3.41)] or poor psychiatric well-being [odds ratio 2.36 (95% confidence interval 1.92-2.90)]. However, there were no significant associations between program-level resident wellness and any of the independently, objectively measured postoperative American College of Surgeons National Surgical Quality improvement Program outcomes examined. CONCLUSIONS: Although surgical residents with poor wellness were more likely to self-report a harmful medical error, there was not a higher rate of objectively reported outcomes for surgical patients treated at hospitals with higher rates of burnout or poor psychiatric well-being.

BACKGROUND: Hepatic artery infusion pump (HAIP) chemotherapy is an advanced cancer therapy for primary and secondary hepatic malignancies. The risk of concurrent hepatic and/or colorectal operations with HAIP placement is unknown. Our objective was to characterize the short-term outcomes of concurrent surgery with HAIP placement. METHODS: The 2005-2017 ACS NSQIP dataset was queried for patients undergoing hepatic and colorectal operations with or without HAIP placement. Outcomes were compared for HAIP placement with different combined procedures. Patients who underwent procedures without HAIP placement were propensity score matched with those with HAIP placement. The primary outcome was 30-day death or serious morbidity (DSM). Secondary outcomes included infectious complications, wound complications, length of stay (LOS), and operative time. RESULTS: Of 467 patients who underwent HAIP placement, 83.9% had concurrent surgery. The rate of DSM was 10.7% for HAIP placement alone, 19.2% with concurrent minor hepatic procedures, 22.1% with concurrent colorectal resection, 23.2% with concurrent minor hepatic plus colorectal procedures, 28.4% with concurrent major hepatic resection, and 41.7% with concurrent major hepatic plus colorectal resection. On matched analyses, there was no difference in DSM, infectious, or wound complications for procedures with HAIP placement compared with the additional procedure alone, but operative time (294.7 vs 239.8 min, difference 54.9, 95% CI 42.8-67.0) and LOS (6 vs 5, IRR 1.20, 95% CI 1.08-1.33) were increased. CONCLUSIONS: HAIP placement is not associated with additional morbidity when performed with hepatic and/or colorectal surgery. Decisions regarding HAIP placement should consider the risks of concurrent operations, and patient- and disease-specific factors.

BACKGROUND: Post hepatectomy liver failure (PHLF) is associated with significant perioperative morbidity and mortality. A tool to identify patients at risk for PHLF may allow for earlier intervention to mitigate its severity and help clinicians when counseling patients. Our objective was to develop a PHLF risk calculator. STUDY DESIGN: Patients who underwent hepatectomy for any indication from 2014 to 2017 were identified from ACS NSQIP. A multivariable logistic regression model was developed that included preoperative and intraoperative variables. Model fit was assessed for discrimination using the C-statistic, and calibration using Hosmer and Lemeshow (HL) Chi square. Validation of the calculator was performed utilizing tenfold cross validation. RESULTS: Among 15,636 hepatectomy patients analyzed, the overall incidence of clinically significant PHLF was 2.8%. Preoperative patient factors associated with increased PHLF were male gender, preoperative ascites within 30 days of surgery, higher ASA class, preoperative total bilirubin greater than 1.2 mg/dl, and AST greater than 40 units/l. Disease related factors associated with PHLF included histology, and use of neoadjuvant therapy. Intraoperative factors associated with PHLF were extent of resection, open surgical approach, abnormal liver texture, and biliary reconstruction. The calculator's C-statistic was 0.83 and the HL Chi square was 10.9 (p = 0.21) demonstrating excellent discrimination and calibration. On tenfold cross validation, the mean test group C-statistic was 0.82 and the HL p value was 0.26. CONCLUSION: We present a multi-institutional preoperative and early postoperative PHLF risk calculator, which demonstrated excellent discrimination and calibration. This tool can be used to help identify high-risk patients to facilitate earlier interventions.

BACKGROUND: Prophylactic drainage following hepatectomy is frequently performed despite evidence that drainage is unnecessary. It is unknown to what extent drain use is influenced by hospital practice patterns. The objectives of this study were to identify factors associated with the use of prophylactic drains following hepatectomy and assess hospital variation in drain use. METHODS: Retrospective cohort study of patients following hepatectomy without concomitant bowel resection or biliary reconstruction from the ACS NSQIP Hepatectomy Targeted Dataset. Factors associated with the use of prophylactic drains were identified using multivariable logistic regression and hospital-level variation in drain use was assessed. RESULTS: Analysis included 10,530 patients at 130 hospitals. Overall, 42.3% of patients had a prophylactic drain placed following hepatectomy. Patients were more likely to receive prophylactic drains if they were ≥65 years old (adjusted odds ratio [aOR]: 1.34, 95%CI: 1.16-1.56), underwent major hepatectomy (aOR: 1.42, 95%CI 1.15-1.74), or had an open resection (aOR 1.94, 95%CI 1.49-2.53). There was notable hospital variability in drain use (range: 0%-100% of patients), and 77.5% of measured variation was at the hospital level. CONCLUSION: Prophylactic drains are commonly placed in both major and minor hepatectomy. Hospital-specific patterns appear to be a major driver and represent a target for improvement.

The National Surgical Quality Program (NSQIP) Transplant was designed by transplant surgeons from the ground up to track posttransplant outcomes beyond basic recipient and graft survival. After an initial pilot phase, the program has expanded to 29 participating sites and enrolled more than 4300 recipient-donor pairs into the database, including 2876 complete kidney transplant cases. In this analysis, surgical site infection (SSI), urinary tract infection (UTI), and reoperation/intervention were evaluated for kidney transplant recipients. We observed impressive variation in the crude incidence between sites for SSI (0%-17%), UTI (0%-14%), and reoperation/intervention (0%-25%). After adjustment for donor and recipient factors, 2 sites were outliers with respect to their incidence of UTI. For the first time, the field of transplantation has data that demonstrate variation in kidney recipient surgical outcomes between sites. More importantly, NSQIP Transplant provides a powerful platform to improve care beyond basic patient and graft survival.

After an initial pilot phase, the program has expanded to 29 participating sites and enrolled more than 4300 recipient-donor pairs into the database, including 1444 completed liver transplant cases. In this analysis, surgical site infection (SSI), urinary tract infection (UTI), and unplanned reoperation/intervention after liver transplantation were evaluated. We observed impressive variation in the crude incidence between sites for SSI (0%-29%), UTI (0%-10%), and reoperation/intervention (0%-57%). After adjustment for donor and recipient factors, at least 1 site was identified as an outlier for each of the analyzed outcomes. For the first time, the field of transplantation has data that demonstrate variation in liver recipient outcomes beyond death and graft survival between sites. More importantly, NSQIP Transplant provides a powerful platform to improve care beyond basic patient and graft survival.

BACKGROUND: Concerns persist regarding the effect of current surgical resident duty-hour policies on patient outcomes, resident education, and resident well-being. METHODS: We conducted a national, cluster-randomized, pragmatic, noninferiority trial involving 117 general surgery residency programs in the United States (2014-2015 academic year). Programs were randomly assigned to current Accreditation Council for Graduate Medical Education (ACGME) duty-hour policies (standard-policy group) or more flexible policies that waived rules on maximum shift lengths and time off between shifts (flexible-policy group). Outcomes included the 30-day rate of postoperative death or serious complications (primary outcome), other postoperative complications, and resident perceptions and satisfaction regarding their well-being, education, and patient care. RESULTS: In an analysis of data from 138,691 patients, flexible, less-restrictive duty-hour policies were not associated with an increased rate of death or serious complications (9.1% in the flexible-policy group and 9.0% in the standard-policy group, P=0.92; unadjusted odds ratio for the flexible-policy group, 0.96; 92% confidence interval, 0.87 to 1.06; P=0.44; noninferiority criteria satisfied) or of any secondary postoperative outcomes studied. Among 4330 residents, those in programs assigned to flexible policies did not report significantly greater dissatisfaction with overall education quality (11.0% in the flexible-policy group and 10.7% in the standard-policy group, P=0.86) or well-being (14.9% and 12.0%, respectively; P=0.10). Residents under flexible policies were less likely than those under standard policies to perceive negative effects of duty-hour policies on multiple aspects of patient safety, continuity of care, professionalism, and resident education but were more likely to perceive negative effects on personal activities. There were no significant differences between study groups in resident-reported perception of the effect of fatigue on personal or patient safety. Residents in the flexible-policy group were less likely than those in the standard-policy group to report leaving during an operation (7.0% vs. 13.2%, P<0.001) or handing off active patient issues (32.0% vs. 46.3%, P<0.001). CONCLUSIONS: As compared with standard duty-hour policies, flexible, less-restrictive duty-hour policies for surgical residents were associated with noninferior patient outcomes and no significant difference in residents' satisfaction with overall well-being and education quality.

BACKGROUND: Pancreatic fistula remains common, with limited ability to risk stratify patients preoperatively. The objective of this study was to identify risk factors for clinically-relevant postoperative pancreatic fistula (CR-POPF) that are routinely available in the preoperative setting. METHODS: Preoperatively available variables for all pancreaticoduodenectomies from 2014-2017 were examined using a national clinical registry. The cohort was separated into risk factor identification and internal validation subgroups. RESULTS: Among 15 033 pancreaticoduodenectomies, the CR-POPF rate was 16.7%. CR-POPF was more likely in patients that were male (odds ratio [OR], 1.51), obese (body mass index [BMI] > 30, OR, 1.97), had minimal preoperative weight loss (OR, 1.25), had a nondilated pancreatic duct (OR, 1.81), did not have diabetes, (OR, 1.80), did not receive neoadjuvant therapy (OR, 1.78), had no evidence of biliary obstruction (OR, 1.18), or had nonadenocarcinoma pathology (OR, 1.96; all P < 0.01). Patients with three or fewer risk factors had a CR-POPF rate of 7.1%, while those with six or more risk factors had a CR-POPF rate of 26.3% (P < 0.001). CONCLUSION: Preoperative CR-POPF risk evaluation could be a useful tool in patient counseling and surgical planning, and risk may allow for more well-informed decisions regarding perioperative management, including enhanced recovery protocols and use of somatostatin analogs.

BACKGROUND AND OBJECTIVES: Delayed gastric emptying (DGE) occurs commonly following pancreaticoduodenectomy (PD), but the rate of DGE in the absence of other intra-abdominal complications is poorly understood. The objectives of this study were to define the incidence of DGE and identify risk factors for DGE in patients without pancreatic fistula or other intra-abdominal infections. METHODS: Retrospective cohort study utilizing the American College of Surgeons National Surgical Quality Improvement Program pancreatectomy variables to identify patients with DGE following PD without evidence of fistula or intra-abdominal infection. Multivariable models were developed to assess preoperative, intraoperative, and technical factors associated with DGE. RESULTS: The rate of DGE was 11.7% in 10502 cases without pancreatic fistula or intra-abdominal infection. Patients were more likely to develop DGE if age ≥75 (odds ratio [OR], 1.22; P = 0.003), male (OR, 1.29; P < 0.001), underwent pylorus-sparing PD (OR, 1.27; P = 0.004), or had a prolonged operative time (OR, 1.38 if greater than seven vs less than 5 hours; P = 0.005). Factors not associated with DGE included BMI, pathologic indication, and surgical approach. CONCLUSION: The incidence of DGE after PD is notable even in patients without other abdominal complications. Identification of patients at increased risk for DGE may aid patient counseling as well as decisions regarding surgical technique, enteral feeding access, and enhanced-recovery pathways.

OBJECTIVE: To explore hospital-level variation in postoperative delirium using a multi-institutional data source. BACKGROUND: Postoperative delirium is closely related to serious morbidity, disability, and death in older adults. Yet, surgeons and hospitals rarely measure delirium rates, which limits quality improvement efforts. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Geriatric Surgery Pilot (2014 to 2015) collects geriatric-specific variables, including postoperative delirium using a standardized definition. Hierarchical logistic regression models, adjusted for case mix [Current Procedural Terminology (CPT) code] and patient risk factors, yielded risk-adjusted and smoothed odds ratios (ORs) for hospital performance. Model performance was assessed with Hosmer-Lemeshow (HL) statistic and c-statistics, and compared across surgical specialties. RESULTS: Twenty thousand two hundred twelve older adults (≥65 years) underwent inpatient operations at 30 hospitals. Postoperative delirium occurred in 2427 patients (12.0%) with variation across specialties, from 4.7% in gynecology to 13.7% in cardiothoracic surgery. Hierarchical modeling with 20 risk factors (HL = 9.423, P = 0.31; c-statistic 0.86) identified 13 hospitals as statistical outliers (5 good, 8 poor performers). Per hospital, the median risk-adjusted delirium rate was 10.4% (range 3.2% to 27.5%). Operation-specific risk and preoperative cognitive impairment (OR 2.9, 95% confidence interval 2.5-3.5) were the strongest predictors. The model performed well across surgical specialties (orthopedic, general surgery, and vascular surgery). CONCLUSION: Rates of postoperative delirium varied 8.5-fold across hospitals, and can feasibly be measured in surgical quality datasets. The model performed well with 10 to 12 variables and demonstrated applicability across surgical specialties. Such efforts are critical to better tailor quality improvement to older surgical patients.

BACKGROUND: Current preoperative cardiac risk stratification practices group operations into broad categories, which might inadequately consider the intrinsic cardiac risks of individual operations. We sought to define the intrinsic cardiac risks of individual operations and to demonstrate how grouping operations might lead to imprecise estimates of perioperative cardiac risk. METHODS: Elective operations (based on Common Procedural Terminology codes) performed from January 1, 2010 to December 31, 2015 at hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program were studied. A composite measure of perioperative adverse cardiac events was defined as either cardiac arrest requiring cardiopulmonary resuscitation or acute myocardial infarction. Operations' intrinsic cardiac risks were derived from mixed-effects models while controlling for patient mix. Resultant risks were sorted into low-, intermediate-, and high-risk categories, and the most commonly performed operations within each category were identified. Intrinsic operative risks were also examined using a representative grouping of operations to portray within-group variation. RESULTS: Sixty-six low, 30 intermediate, and 106 high intrinsic cardiac risk operations were identified. Excisional breast biopsy had the lowest intrinsic cardiac risk (overall rate, 0.01%; odds ratio, 0.11; 95% CI, 0.02 to 0.25) relative to the average, whereas aorto-bifemoral bypass grafting had the highest (overall rate, 4.1%; odds ratio, 6.61; 95% CI, 5.54 to 7.90). There was wide variation in the intrinsic cardiac risks of operations within the representative grouping (median odds ratio, 1.40; interquartile range, 0.88 to 2.17). CONCLUSIONS: A continuum of intrinsic cardiac risk exists among operations. Grouping operations into broad categories inadequately accounts for the intrinsic cardiac risk of individual operations.

BACKGROUND: This study aimed to determine whether (1) the propensity for concurrent fundoplication during gastrostomy varies among hospitals, and (2) postoperative morbidity differs among institutions performing fundoplication more or less frequently. METHODS: Children who underwent gastrostomy with or without concurrent fundoplication were identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric (ACS-NSQIP-P). A hierarchical multivariate regression modeled the excess effects that hospitals exerted over propensity for concurrent fundoplication adjusting for preoperative clinical variables. Hospitals were designated as low outliers (significantly lower-adjusted odds of concurrent fundoplication than the average hospital with similar patient mix), average hospitals, and high outliers based on their risk-adjusted concurrent fundoplication practice. The postoperative morbidity rates were compared among low-outlier, average, and high-outlier hospitals. RESULTS: Between 2011 and 2013, 3775 children underwent gastrostomy at one of 54 ACS-NSQIP-P participating hospitals. The mean hospital concurrent fundoplication rate was 11.7% (range 0-64%). There was no significant difference in unadjusted morbidity rate in children with concurrent fundoplication, 11.0% compared to 9.7% in children without concurrent fundoplication. After controlling for clinical variables, 8 hospitals were identified as low outliers (fundoplication rate of 0.4%) and 16 hospitals were identified as high outliers (fundoplication rate of 34.6%). The average unadjusted morbidity rate among hospitals with low, average, and high odds of concurrent fundoplication were 9.6, 10.6, and 8.4%, respectively. CONCLUSION: Hospitals vary significantly in propensity for concurrent fundoplication during gastrostomy yet postoperative morbidity does not differ significantly among institutions performing fundoplication more or less frequently.

OBJECTIVE: To determine whether concurrently performed operations are associated with an increased risk for adverse events. BACKGROUND: Concurrent operations occur when a surgeon is simultaneously responsible for critical portions of 2 or more operations. How this practice affects patient outcomes is unknown. METHODS: Using American College of Surgeons' National Surgical Quality Improvement Program data from 2014 to 2015, operations were considered concurrent if they overlapped by ≥60 minutes or in their entirety. Propensity-score-matched cohorts were constructed to compare death or serious morbidity (DSM), unplanned reoperation, and unplanned readmission in concurrent versus non-concurrent operations. Multilevel hierarchical regression was used to account for the clustered nature of the data while controlling for procedure and case mix. RESULTS: There were 1430 (32.3%) surgeons from 390 (77.7%) hospitals who performed 12,010 (2.3%) concurrent operations. Plastic surgery (n = 393 [13.7%]), otolaryngology (n = 470 [11.2%]), and neurosurgery (n = 2067 [8.4%]) were specialties with the highest proportion of concurrent operations. Spine procedures were the most frequent concurrent procedures overall (n = 2059/12,010 [17.1%]). Unadjusted rates of DSM (9.0% vs 7.1%; P < 0.001), reoperation (3.6% vs 2.7%; P < 0.001), and readmission (6.9% vs 5.1%; P < 0.001) were greater in the concurrent operation cohort versus the non-concurrent. After propensity score matching and risk-adjustment, there was no significant association of concurrence with DSM (odds ratio [OR] 1.08; 95% confidence interval [CI] 0.96-1.21), reoperation (OR 1.16; 95% CI 0.96-1.40), or readmission (OR 1.14; 95% CI 0.99-1.29). CONCLUSIONS: In these analyses, concurrent operations were not detected to increase the risk for adverse outcomes. These results do not lessen the need for further studies, continuous self-regulation and proactive disclosure to patients.

BACKGROUND: The American College of Surgeons, National Surgical Quality Improvement Program (ACS NSQIP) surgical quality feedback models are recalibrated every 6 months, and each hospital is given risk-adjusted, hierarchical model, odds ratios that permit comparison to an estimated average NSQIP hospital at a particular point in time. This approach is appropriate for "relative" benchmarking, and for targeting quality improvement efforts, but does not permit evaluation of hospital or program-wide changes in quality over time. We report on long-term improvement in surgical outcomes associated with participation in ACS NSQIP. STUDY DESIGN: ACS NSQIP data (2006-2013) were used to create prediction models for mortality, morbidity (any of several distinct adverse outcomes), and surgical site infection (SSI). For each model, for each hospital, and for year of first participation (hospital cohort), hierarchical model observed/expected (O/E) ratios were computed. The primary performance metric was the within-hospital trend in logged O/E ratios over time (slope) for mortality, morbidity, and SSI. RESULTS: Hospital-averaged log O/E ratio slopes were generally negative, indicating improving performance over time. For all hospitals, 62%, 70%, and 65% of hospitals had negative slopes for mortality, morbidity, and any SSI, respectively. For hospitals currently in the program for at least 3 years, 69%, 79%, and 71% showed improvement in mortality, morbidity, and SSI, respectively. For these hospitals, we estimate 0.8%, 3.1%, and 2.6% annual reductions (with respect to prior year's rates) for mortality, morbidity, and SSI, respectively. CONCLUSIONS: Participation in ACS NSQIP is associated with reductions in adverse events after surgery. The magnitude of quality improvement increases with time in the program.

BACKGROUND: Surgical quality improvement depends on hospitals having accurate and timely information about comparative performance. Profiling accuracy is improved by risk adjustment and shrinkage adjustment to stabilize estimates. These adjustments are included in ACS NSQIP reports, where hospital odds ratios (OR) are estimated using hierarchical models built on contemporaneous data. However, the timeliness of feedback remains an issue. STUDY DESIGN: We describe an alternative, nonhierarchical approach, which yields risk- and shrinkage-adjusted rates. In contrast to our "Traditional" NSQIP method, this approach uses preexisting equations, built on historical data, which permits hospitals to have near immediate access to profiling results. We compared our traditional method to this new "on-demand" approach with respect to outlier determinations, kappa statistics, and correlations between logged OR and standardized rates, for 12 models (4 surgical groups by 3 outcomes). RESULTS: When both methods used the same contemporaneous data, there were similar numbers of hospital outliers and correlations between logged OR and standardized rates were high. However, larger differences were observed when the effect of contemporaneous versus historical data was added to differences in statistical methodology. CONCLUSIONS: The on-demand, nonhierarchical approach provides results similar to the traditional hierarchical method and offers immediacy, an "over-time" perspective, application to a broader range of models and data subsets, and reporting of more easily understood rates. Although the nonhierarchical method results are now available "on-demand" in a web-based application, the hierarchical approach has advantages, which support its continued periodic publication as the gold standard for hospital profiling in the program.

OBJECTIVES: To assess whether hospital rates of secondary complications could serve as a performance benchmark and examine associations with mortality. BACKGROUND: Failure to rescue (death after postoperative complication) is a challenging target for quality improvement. Secondary complications (complications after a first or "index" complication) are intermediate outcomes in the rescue process that may provide specific improvement targets and give us insight into how rescue fails. METHODS: We used American College of Surgeons' National Surgical Quality Improvement Program data (2008-2012) to define hospital rates of secondary complications after 5 common index complications: pneumonia, surgical site infection (SSI), urinary tract infection, transfusion/bleed events, and acute myocardial infarction (MI). Hospitals were divided into quintiles on the basis of risk- and reliability-adjusted rates of secondary complications, and these rates were compared along with mortality. RESULTS: A total of 524,860 patients were identified undergoing one of the 62 elective, inpatient operations. After index pneumonia, secondary complication rates varied from 57.99% in the highest quintile to 22.93% in the lowest [adjusted odds ratio (OR), 4.64; confidence interval (CI), 3.95-5.45). Wide variation was seen after index SSI (58.98% vs 14.81%; OR, 8.53; CI, 7.41-9.83), urinary tract infection (38.41% vs 8.60%; OR, 7.81; CI, 6.48-9.40), transfusion/bleeding events (27.14% vs 12.88%; OR, 2.54; CI, 2.31-2.81), and acute MI (64.45% vs 23.86%, OR, 6.87; CI, 5.20-9.07). Hospitals in the highest quintile had significantly greater mortality after index pneumonia (10.41% vs 6.20%; OR, 2.17; CI, 1.6-2.94), index MI (18.25% vs 9.65%; OR, 2.67; CI, 1.80-3.94), and index SSI (2.75% vs 0.82%; OR, 3.93; CI, 2.26-6.81). CONCLUSIONS: Hospital-level rates of secondary complications (failure to arrest complications) vary widely, are associated with mortality, and may be useful for quality improvement and benchmarking.
