Abstract
BACKGROUND Human error is impossible to eliminate, particularly in systems as complex as healthcare. The extent to which judgment errors in particular impact surgical patient care or lead to harm is unclear. STUDY DESIGN The American College of Surgeons NSQIP (2018) procedures from a single institution with 30-day morbidity or mortality were examined. Medical records were reviewed and evaluated for judgment errors. Preoperative variables associated with judgment errors were examined using logistic regression. RESULTS Of the surgical patients who experienced a morbidity or mortality, 18% (31 of 170) experienced an error in judgment during their hospitalization. Patients with hepatobiliary procedure (odds ratio [OR] 5.4 [95% CI 1.23 to 32.75], p = 0.002), insulin-dependent diabetes (OR 4.8 [95% CI 1.2 to 18.8], p = 0.025), severe COPD (OR 6.0 [95% CI 1.6 to 22.1], p = 0.007), or with infected wounds (OR 8.2 [95% CI 2.6 to 25.8], p < 0.001) were at increased risk for judgment errors. CONCLUSIONS Specific procedure types and patients with certain preoperative variables had higher risk for judgment errors during their hospitalization. Errors in judgment adversely impacted the outcomes of surgical patients who experienced morbidity or mortality in this cohort. Preventing or mitigating errors and closely monitoring patients after an error in judgment is prudent and may improve surgical safety.

Abstract
BACKGROUND Failure to rescue (FTR) is a quality metric defined as mortality after potentially preventable complications after surgery. Predicting patients who are at the highest risk of mortality after a complication may aid in preventing deaths. Thirty-day follow-up period inadequately captures postoperative deaths; alternatively, a 90-day follow-up period has been advocated. This study aimed to examine the association of a validated frailty metric, the risk analysis index (RAI), with 90-day FTR (FTR-90). METHODS Patients aged ≥65 years who underwent a major abdominal operation between 2014 and 2020 at a quaternary care center were abstracted. Institutional data were merged with the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and Geriatric Surgery Research File variables. The association between RAI and FTR-90 was evaluated using multivariable logistic regression. RESULTS A total of 398 patients with postoperative complications were included. Fifty-two patients (13.1%) died during the 90-day follow-up. The FTR-90 group was older (median age: 76 vs 73 years, respectively; P = .002), had a greater preoperative American Society of Anesthesiologists classification score (P < .001), and had a higher ACS NSQIP estimated risk of morbidity (0.33% vs 0.20%, P < .001) and mortality (0.067% vs 0.012%, P < .001). The FTR-90 group had a greater median RAI score (23 vs 19; P = .002). The RAI score was independently associated with FTR-90 (odds ratio, 1.04; 95% CI, 1.0042-1.0770; P = .028) but not with FTR-30 (P = .13). CONCLUSION Preoperative frailty, as defined by RAI, is independently associated with FTR at 90-day follow-up. FTR-90 captured nearly 60% more deaths than did FTR-30. Frailty has major implications beyond the typical 30-day follow-up period, and a longer follow-up period must be considered.

Abstract
BACKGROUND The risk of venous thromboembolism (VTE) after hepatopancreatobiliary (HPB) surgery is high. Extended postdischarge prophylaxis in this patient population has been controversial. This study aimed to examine the safety of postdischarge extended VTE prophylaxis in patients at high risk of VTE events after HPB surgery. METHODS Adult patients risk stratified as very high risk of VTE who underwent HPB operations between 2014 and 2020 at a quaternary care center were included. Patients were matched 1:2 extended VTE prophylaxis to the control group (patients who did not receive extended prophylaxis). Analyses compared the proportions of adverse bleeding events between groups. RESULTS A total of 307 patients were included: 103 in the extended prophylaxis group and 204 in the matched control group. Demographics were similar between groups. More patients in the extended VTE prophylaxis group had a history of VTE (9% vs 3%; P = .045). There was no difference in bleeding events between the extended VTE prophylaxis and the control group (6% vs 2%; P = .091). Of the 6 patients with bleeding events in the VTE prophylaxis group, 5 had gastrointestinal (GI) bleeding, and 1 had hemarthrosis. Of the 4 patients with bleeding events in the control group, 1 had intra-abdominal bleeding, 2 had GI bleeding, and 1 had intra-abdominal and GI bleeding. CONCLUSION Patients discharged with extended VTE prophylaxis after HPB surgery did not experience more adverse bleeding events compared with a matched control group. Routine postdischarge extended VTE prophylaxis is safe in patients at high risk of postoperative VTE after HPB surgery.

Abstract
INTRODUCTION Long-term data evaluating clinical outcomes in patients with branch-duct Intraductal papillary mucinous neoplasms (BD-IPMN) without high-risk stigmata (HRS) or worrisome features (WF) remain limited. METHODS This observational cohort study included all patients diagnosed with BD-IPMN without HRS or WF between 2003 and 2019 who were enrolled in a prospective surveillance program. Time-to-progression analysis was performed using a cumulative incidence function plot and survival analysis was conducted using Kaplan-Meier. RESULTS The median follow-up time for the 267 patient cohort was 44.5 months (interquartile range [IQR]: 24.1-72.2). Radiographic cyst growth was observed in 123 (46.1%) patients; 65 (24.3%) patients progressed to WF/HRS. Twenty-six (9.7%) patients were selected for resection during surveillance: 21 (80.8%) WF, 4 (15.4%) HRS; 1 (3.9%) transformed to mixed-duct. Of all the patients who underwent resection, 5 (19.2%) had adenocarcinoma, and 1 (3.8%) had carcinoma-in-situ. The probability of any radiographic progression was 21.3% (5-year) and 51.3% (10-year). For the entire cohort, there was 1.1% mortality secondary to pancreatic adenocarcinoma and 8.2% all-cause mortality. The 5-year overall survival rate was 91.5%, and at 10 years, 81.5%. CONCLUSION Approximately one in four patients with nonworrisome BD-IPMN have progression to WF/HRS stigmata during surveillance. However, the risk of malignant transformation remains low. Surveillance strategy remains prudent in this patient population.

Abstract
INTRODUCTION Medicaid expansion's (ME) impact on postoperative outcomes after abdominal surgery remains poorly defined. We aimed to evaluate ME's effect on surgical morbidity, mortality, and readmissions in a state that expanded Medicaid (Virginia) compared to a state that did not (Tennessee) over the same time period. METHODS Virginia Surgical Quality Collaborative (VSQC) American College of Surgeons National Surgical Quality Improvement Program data for Medicaid, uninsured, and private insurance patients undergoing abdominal procedures before Virginia's ME (3/22/18-12/31/18) were compared with post-ME (1/1/19-12/31/19), as were corresponding non-ME state Tennessee Surgical Quality Collaborative (TSQC) data for the same 2018 and 2019 time periods. Postexpansion odds ratios for 30-d morbidity, 30-d mortality, and 30-d unplanned readmission were estimated using propensity score-adjusted logistic regression models. RESULTS In Virginia, 4753 abdominal procedures, 2097 pre-ME were compared to 2656 post-ME. In Tennessee, 5956 procedures, 2484 in 2018 were compared to 3472 in 2019. VSQC's proportion of Medicaid population increased following ME (8.9% versus 18.8%, P < 0.001) while uninsured patients decreased (20.4% versus 6.4%, P < 0.001). Post-ME VSQC had fewer 30-d readmissions (12.2% versus 6.0%, P = 0.013). Post-ME VSQC Medicaid patients had significantly lower probability of morbidity (-8.18, 95% confidence interval: -15.52 ∼ -0.84, P = 0.029) and readmission (-6.92, 95% confidence interval: -12.56 ∼ -1.27, P = 0.016) compared to pre-ME. There were no differences in probability of morbidity or readmission in the TSQC Medicaid population between study periods (both P > 0.05); there were no differences in mortality between study periods in VSQC and TSQC patient populations (both P > 0.05). CONCLUSIONS ME was associated with decreased 30-d morbidity and unplanned readmissions in the VSQC. Data-driven policies accounting for ME benefits should be considered.

Abstract
BACKGROUND Traditional surgical outcomes are measured retrospectively and intermittently, limiting opportunities for early intervention. OBJECTIVES The objective of this study was to use risk-adjusted cumulative sum (RA-CUSUM) to track perioperative surgical outcomes for laparoscopic gastric bypass. We hypothesized that RA-CUSUM could identify performance variations between surgeons. SETTING Two mid-Atlantic quaternary care academic centers. METHODS Patient-level data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) were abstracted for laparoscopic gastric bypasses performed by 3 surgeons at 2 high-volume centers from 2014 to 2021. Estimated probabilities of serious complications, reoperation, and readmission were derived from the MBSAQIP risk calculator. RA-CUSUM curves were generated to signal observed-to-expected odds ratios (ORs) of 1.5 (poor performance) and .5 (superior performance). Control limits were set based on a false positive rate of 5% (α = .05). RESULTS We included 1192 patients: Surgeon A = 767, Surgeon B = 188, and Surgeon C = 237. Overall rates of serious complications, 30-day reoperations, and 30-day readmissions were 3.9%, 2.5%, and 5.2% respectively, with expected rates of 4.7%, 2.2%, and 5.8%. RA-CUSUM signaled lower-than-expected (OR < .5) rates of readmission and serious complication in Surgeon A, and higher-than-expected (OR > 1.5) readmission rate in Surgeon C. Surgeon A further demonstrated an early period of higher-than-expected (OR > 1.5) reoperation rate before April 2015, followed by superior performance thereafter (OR < .5). Surgeon B's performance generally reflected expected standards throughout the study period. CONCLUSIONS RA-CUSUM adjusts for clinical risk factors and identifies performance outliers in real-time. This approach to analyzing surgical outcomes is applicable to quality improvement, root-cause analysis, and surgeon incentivization.

Abstract
BACKGROUND On January 1, 2021, the Centers for Medicare and Medicaid Services implemented a hospital price transparency rule. Consumerism as a means of reducing healthcare expenditure is predicated on informed consumers making discrete choices. STUDY DESIGN For 10 months, immediately after a preoperative clinic visit at an academic medical center, patients and their surgeons were surveyed regarding their estimation of hospital cost and hospital reimbursement for the upcoming operation. Responses were compared to average institutional cost (fiscal year 2019) for Medicare patients undergoing a laparoscopic approach for each operation. We calculated the difference between actual reimbursement and cost with patients' estimates and actual reimbursement and cost with surgeons' estimates. RESULTS Sixty-six questionnaires were collected from patients who underwent laparoscopic operations, that included cholecystectomy (n = 20), inguinal hernia (n = 17), umbilical hernia repair (n = 6), ventral hernia repair (n = 6), incisional hernia (n = 6), hiatal hernia repair (n = 1), and lipoma or cyst excision (n = 10). Patients' estimates of hospital cost exceeded actual hospital cost by a median of $4,502 and were less than hospital reimbursement by a median of $1,834. Surgeon estimates for direct cost were $825 less than hospital direct cost and $1,659 less than hospital reimbursement. CONCLUSIONS Patients as well as their surgeons do not estimate healthcare cost or remuneration accurately and therefore will be ineffective change agents in reducing surgical spending based on price transparency without further education of both parties. Patients consistently overestimated surgical cost while surgeons consistently underestimated surgical cost and reimbursement. It is likely that better-informed surgeons and patients are necessary prerequisites for Centers for Medicare and Medicaid Services price transparency rules to be effective in reducing Medicare expenditures in surgery.

Abstract
BACKGROUND Liver resection is commonly performed for hepatic tumors, however preoperative risk stratification remains challenging. We evaluated the performance of contemporary prediction models for short-term mortality after liver resection in patients with and without cirrhosis. METHODS This retrospective cohort study examined National Surgical Quality Improvement Program data. We included patients who underwent liver resections from 2014 to 2019. VOCAL-Penn, MELD, MELD-Na, ALBI, and Mayo risk scores were evaluated in terms of model discrimination and calibration for 30-day post-operative mortality. RESULTS A total 15,198 patients underwent liver resection, of whom 249 (1.6%) experienced 30-day post-operative mortality. The VOCAL-Penn score had the highest discrimination (area under the ROC curve [AUC] 0.74) compared to all other models. The VOCAL-Penn score similarly outperformed other models in patients with (AUC 0.70) and without (AUC 0.74) cirrhosis. CONCLUSION The VOCAL-Penn score demonstrated superior predictive performance for 30-day post-operative mortality after liver resection as compared to existing clinical standards.

Abstract
BACKGROUND Pursuing pancreatic resection in elderly patients is often complex and limited by concern for functional status and postoperative risk. This study examines the associations between two different preoperative functional status metrics with postoperative outcomes in the geriatric population. METHODS Patients who participated in the ACS NSQIP Geriatric Surgery Research File pilot program (2014-2018) undergoing elective pancreatic operations were included. Two clinically meaningful functional status scores were calculated: the presence of one or more geriatric-specific variable (GSV) and a 5-factor modified frailty index (mFI-5). Multivariable logistic regression adjusting for ACS NSQIP-estimated risk was performed to evaluate associations between preoperative GSV, mFI-5 and 30-day outcome measures. RESULTS A total of 1266 patients were included: 808 (64%) age 65-74, 302 (24%) age 75-80, and 156 (12%) age ≥ 81; 843 (67%) patients underwent pancreatoduodenectomy. Operations were performed for pancreatic adenocarcinoma in 712 (56%) patients. Older patients had greater likelihood of postoperative morbidity (35% vs 31% vs 47%, by age group, p = 0.004) and discharge to a facility (12% vs 23% vs 48%, by age group, p < 0.001). Adjusting for ACS NSQIP predicted risk, patients with a preoperative GSV were more likely to require reoperation and discharge to a facility (OR 1.81 [95% CI 1.03-3.16] and 3.95 [95% CI 2.91-5.38], respectively). The mFI-5 was not associated with postoperative outcomes (all p ≥ 0.18). CONCLUSION The presence of a preoperative GSV is associated with reoperation and discharge to a skilled facility following elective pancreatic resection. Geriatric-specific variables should be considered in joint preoperative decision making to optimize care.

Abstract
Background Venous thromboembolism is a preventable cause of morbidity and mortality after surgery. To ensure that patients receive appropriate venous thromboembolism chemoprophylaxis, a nonmandatory risk-stratification tool based on patient clinical condition was implemented through the electronic health record to stratify patient risk and recommend chemoprophylaxis. We hypothesized that implementing this tool would reduce postoperative venous thromboembolism events in general surgery as well as across all surgical services. Methods All adult patients undergoing inpatient surgical operations (January 2012–December 2019) at a single quaternary care center and Level 1 trauma center were abstracted from institutional electronic health record database and stratified into patients admitted before and after venous thromboembolism risk-stratification tool implementation. Bivariable analyses compared venous thromboembolism chemoprophylaxis prescription and venous thromboembolism events with implementation and screening among all surgical patients as well as in general surgery patient subset. Results A total of 64,377 adults underwent operations: 27,819 preimplementation and 36,558 postimplementation. A significant reduction in venous thromboembolism events occurred from pre- to post-tool implementation for all cases (0.77% vs 0.47%, P < .001). General surgery patients (n = 15,723) had a significant increase in chemoprophylaxis prescription (81.9% vs 86.0%, P < .001) and a significant reduction in venous thromboembolism events (1.41% vs 0.59%, P < .001). After tool implementation, use of extended postdischarge chemoprophylaxis was greater among general surgery patient subset than the entire patient cohort (46.7% vs 29.6%, P < .001). Conclusion The integration of a nonmandatory electronic health record risk-stratification tool was associated with a significant reduction in venous thromboembolism events. Extended chemoprophylaxis was prescribed in nearly half of general surgery patients at very high risk for postdischarge events. Implementing an electronic VTE risk-stratification tool reduced surgical VTE events. Even as a nonmandatory tool, risk stratification led to overall fewer VTE events. Postoperative VTE events were reduced by 39% after the tool was integrated in EHR. With the tool, general surgery had 58% less VTE events and improved prophylaxis use.

Abstract
BACKGROUND AND PURPOSE The Medicare Value-Based Purchasing (VBP) program established performance-based financial incentives for hospitals. We hypothesized that total performance scores (TPS) would vary by hospital type. METHODS Value-Based Purchasing reports were collected from 2015 to 2017 and merged with the Centers for Medicare and Medicaid Services (CMS) Impact File data. A total of 3,005 hospitals were grouped into physician-owned surgical hospitals (POSH), accountable care organizations (ACO), Kaiser, Vizient, and General hospitals. Longitudinal linear mixed-effects models compared temporal differences of TPS and secondary composite outcome, process, patient satisfaction, safety, and cost efficiency measures between hospital types. RESULTS Total performance scores decreased across all hospital types (p < .001). Physician-owned surgical hospitals had the highest TPS (59.9), followed by Kaiser (49.2), ACO (36.7), General (34.8), and Vizient (30.7) (p < .001). Hospital types differed significantly in size, geography, mean case-mix index, Medicare patient discharges, percent Medicare days to inpatient days, Disproportionate Share Hospital payments, and uncompensated care per claim. Scores improved in 84% of POSH and 14.6% of Kaiser hospitals using score reallocations. CONCLUSION In comparison with General hospitals, the TPS was higher for POSH and Kaiser and lower for Vizient in part due to weighting reallocation and individual domain scores. IMPLICATIONS Centers for Medicare and Medicaid Services scoring system changes have not addressed the methodological biases favoring certain hospital types.

Abstract
BACKGROUND Unplanned reoperations and unplanned readmissions can increase morbidity and mortality. Few studies however, have explored the association of reoperation and readmission among general surgery patients. Our aim was to examine this relationship in selected abdominal operations. METHODS Data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use Data Files from 2014 to 2018 were utilized. Six groups of operations, defined by ACS NSQIP procedure codes for ventral hernia repair, colectomy, appendectomy, proctectomy, small bowel resection, and gastrectomy, were assessed. Patients discharged ≤ 14 days after operation were included in the study. This time period was selected to reduce ACS NSQIP 30 day post-surgery follow-up bias. Unplanned reoperations were defined as those occurring during the index hospitalization. The primary outcome was unplanned readmission that occurred ≤ 14 days from the date of discharge. Logistic regression models were used to examine variables associated with unplanned readmission for each procedure group. RESULTS A total of 787,118 patients were included: ventral hernia repair 35.2%, colectomy 30.6%, appendectomy 26.5%, proctectomy 3.7%, small bowel resection 3.2%, and gastrectomy 0.8%. Unplanned reoperation was independently associated with unplanned readmission for ventral hernia repair (OR 2.84, 95% CI 2.28-3.54, P < 0.001), colectomy (OR 1.58, CI 1.42- 1.76, P < 0.001), appendectomy (OR 2.91, CI 2.21-3.84, P < 0.001), and proctectomy (OR 1.41, CI 1.10-1.81, P = 0.006). Other clinically relevant covariates associated with readmission were partially dependent functional status before colectomy (OR 1.34, CI 1.23-1.46, P < 0.001), ventral hernia repair (OR 1.79, CI 1.54-2.09, P < 0.001), and small bowel resection (OR 1.44, CI 1.18-1.77, P < 0.001; and ASA 4/5 classification for colectomy (OR 2.71, CI 2.36-3.11, P < 0.001), proctectomy (OR 2.10, CI 1.48-2.97, P < 0.001), ventral hernia repair (OR 8.19, CI 6.78-9.88, P < 0.001), appendectomy (OR 2.80, CI 2.35-3.34, P < 0.001), and small bowel resection (OR 3.42, CI 2.20-5.32, P < 0.001). ASA 2, ASA 3 classification, age, and sex were also associated with unplanned readmission for most procedures. CONCLUSIONS Unplanned reoperations are associated with an increase in unplanned readmission after selected abdominal operations included in this study. This factor should be considered in discharge and follow-up planning to help reduce unplanned readmissions.

Abstract
BACKGROUND The impact of obesity on postoperative outcomes after pancreatoduodenectomy remains insufficiently studied. METHODS All pancreatoduodenectomy patients were abstracted from the 2014 to 2018 American College of Surgeons National Surgical Quality Improvement Program data sets and were stratified into the following 3 body mass index categories: non-obese (body mass index 18.5-29.9), class 1/2 obesity (body mass index 30-39.9), and class 3 severe obesity (body mass index ≥ 40). Analyses tested associations between patient factors and four 30-day postoperative outcomes: mortality, composite morbidity, delayed gastric emptying, and postoperative pancreatic fistula. Multivariable logistic regression models tested independent associations between patient factors and these 4 outcome measures. RESULTS A total of 16,823 patients were included in the study: 12,234 (72.7%) non-obese, 4,030 (24%) obese, and 559 (3.3%) with severe obesity. Bivariable analyses demonstrated significant associations between obesity, severe obesity, and greater proportions of numerous preoperative comorbidities as well as a greater likelihood of postoperative complications, including postoperative pancreatic fistula, delayed gastric emptying, composite morbidity, and mortality (all P ≤ .001). After adjusting for significant covariates, obesity was independently associated with postoperative pancreatic fistula (odds ratio 1.49, 95% confidence interval: 1.33-1.67, P < .001), delayed gastric emptying (odds ratio 1.16, 95% confidence interval: 1.05-1.28, P = .004), composite morbidity (odds ratio 1.28, 95% confidence interval: 1.18-1.38, P < .001), and mortality (odds ratio 1.79, 95% confidence interval: 1.36-2.36, P < .001). CONCLUSION Obesity and severe obesity are significantly associated with worse short-term outcomes after pancreatoduodenectomy. Preoperative considerations, such as weight management strategies during individualized treatment planning, could improve outcomes in this population.

Abstract
BACKGROUND Relationships between surgical errors and adverse events have not been fully explored and were examined in this study. MATERIALS AND METHODS This retrospective cohort study reviewed records of deceased surgical patients over 12 months. Bivariate associations between predictors and errors were examined. RESULTS 84 deaths occurred following 5,209 operations. Errors in care (63%) compared to those without had significantly more adverse events, (98% vs 80% respectively, p = 0.004). Significant association occurred between error and emergency status, p = 0.016); length of stay >10 days, p = 0.011; adverse events, p = 0.005). Regression results indicated number of adverse events (OR = 1.27, 95% CI (1.08-1.49), p = 0.003) and length of stay (OR = 1.05, 95% CI (1.01-1.09), p = 0.008) were associated with surgical errors. CONCLUSIONS Examining postoperative adverse events in error cases identified opportunities for improvement. Reducing medical errors requires measuring medical errors.

Abstract
BACKGROUND Preoperative assessment of geriatric-specific determinants of health may enhance perioperative risk stratification among elderly patients. This study examines effects of geriatric-specific variables on postoperative outcomes in patients undergoing elective major abdominal operations. METHODS Patients included in the ACS NSQIP pilot Geriatric Surgery Research File program who underwent elective pancreatic, liver, and colorectal operations between 2014 and 2016 were examined. Multivariable analyses were performed to evaluate associations between patient-specific geriatric variables and risk of death, morbidity, readmission, and discharge destination. RESULTS A total of 4165 patients were included. Patients ≥85 years were more likely to die, experience postoperative morbidity, and be discharged to a facility (all p ≤ 0.039) than younger patients. Preoperatively, patients ≥85 years were more likely to use a mobility aid, have a prior fall, have consent signed by a surrogate, and to live alone at home prior to operation (all p < 0.001). After adjustment for ACS NSQIP-estimated probabilities of morbidity or mortality, no geriatric-specific preoperative risk factors were significantly associated with increased risk of death or complications in any age group (all p > 0.055). Patients 75-84 and ≥85 years were more likely to be discharged to facility (OR 2.33 and 4.75, respectively, both p < 0.001) compared to patients 65-74 years. All geriatric-specific variables: use of mobility aid, living alone, consent signed by a surrogate, and fall history, were significantly associated with discharge to a facility (all p ≤ 0.001). CONCLUSIONS After adjusting for comorbid conditions, geriatric-specific variables are not associated with postoperative mortality and morbidity among elderly patients; however, geriatric-specific variables are significantly associated with discharge to a facility.

Abstract
BACKGROUND Elderly patients (65 years of age and older) undergo an increasing number of operations performed annually in the US and they present with unique healthcare needs. Preventing postoperative readmission remains an important challenge to improving surgical care. This study examined whether geriatric-specific variables were independently associated with postoperative readmissions of elderly patients. METHODS The American College of Surgeons (ACS) Geriatric Surgery Research File (GSRF) was joined with the ACS NSQIP Participant Use Data Files for 2014 to 2016. This data set included 13 GSRF variables and 26 ACS NSQIP variables. Associations between clinically relevant variables and readmission were tested with multivariable logistic regression. RESULTS The data represented 6,039 general surgery patients age 65 years and older. Fifty-eight percent of patients had colorectal operations, 19% pancreatic or hepatobiliary, 15% hernia, 4% thyroid or esophageal, and 3% had appendix operations. Twenty-four percent of patients experienced an NSQIP-defined 30-day postoperative complication and 3% died within 30 days after operation. Eleven percent of patients had unplanned 30-day readmission. Standard NSQIP variables, including 30-day composite morbidity (odds ratio [OR] 5.11; 95% CI, 4.24 to 6.16; p < 0.001), reoperation (OR 2.8; 95% CI, 2.07 to 3.79; p < 0.001), and steroid use (1.42; 95% CI, 1.03 to 1.96; p = 0.03) were associated with readmission. In addition, GSRF variables, including incompetent on admission (OR 1.63; 95% CI, 1.11 to 2.38; p = 0.01), fall risk at discharge (OR 1.42; 95% CI, 1.11 to 1.82; p = 0.005), use of mobility aid (OR 1.26; 95% CI, 1.02 to 1.56; p = 0.03), and discharged home with skilled care (OR, 1.22; 95% CI, 1.0 to 1.49; p = 0.04) were associated with readmission. CONCLUSIONS Four GSRF and 3 current standard ACS NSQIP variables were important in the evaluation of postoperative readmission of elderly patients. Geriatric-specific variables contributed to the explanation of the relationship between clinical variables and readmissions in elderly surgical patients.

Abstract
BACKGROUND Independent associations between chronic liver disease, MELD, and postoperative outcomes among patients selected for liver resection have not been completely established. We hypothesized independent associations between MELD, cirrhosis, and postoperative mortality. METHODS Patient-level data from the targeted hepatectomy module and ACS NSQIP PUF during 2014-2015 were merged. Multivariable regression models with interaction effect between MELD and liver texture (normal, congested/fatty, cirrhotic) tested the independent effects of covariates on mortality and morbidity. RESULTS 3,530 patients were included, of whom 668 patients (19%) had cirrhosis. ACS NSQIP defined mortality (3.9%vs1.1%) and morbidity (23.5%vs15.8%) were higher in patients with cirrhosis (both p < 0.001). In multivariable models, cirrhosis (OR = 2.24; 95%CI:1.16-4.34, p = 0.016) and MELD (OR = 1.10; 95%CI:1.03-1.18, p = 0.007) were independently associated with mortality. MELD (OR = 1.04; 95%CI:1.002-1.08, p = 0.038) was associated with postoperative morbidity. CONCLUSIONS Higher MELD and presence of cirrhosis have an independent negative effect on mortality after liver resection. MELD could be used to estimate postoperative risk in patients with and without cirrhosis.

Abstract
BACKGROUND Perioperative efficiency has been studied, although little is known about patient and personnel factors associated with a timely operating room start. We hypothesize that patient, personnel factors, and induction-order decisions are associated with anesthesia induction time. METHODS An institutional database was used to identify the anesthesia induction time of adults undergoing first-start, elective operations from January 2014 to May 2017 at an academic quaternary care center. Data included patient demographics; surgeon and anesthesiologist, as well as their seniority (years since initial board certification); certified registered nurse anesthetist versus anesthesia resident staffing; and use of neuraxial anesthesia. Times were measured as minutes from scheduled start to induction. Univariate and multivariate analyses were performed to identify factors associated with induction time. RESULTS We identified 15,823 cases. Predictors of later induction included add-on cases (1,224 cases were add-ons, 7.73%), American Society of Anesthesiologists classification ≥ 3, neuraxial anesthesia, and certified registered nurse anesthetist staffing. Surgeon seniority-but not gender-affected induction time. In 11,093 cases (70.1%), the anesthesiologist was scheduled for multiple first starts with a choice of which patient to induce first. Surgeon gender was predictive of induction order, with cases of male surgeons induced first more frequently than female surgeons' (47.0% vs 44.1%, P = .02). Cases staffed by anesthesiology residents were more likely to be induced first compared with those staffed by certified registered nurse anesthetists (52.1% vs 41.5%, P < .01). CONCLUSION Patient and personnel factors affect the order of case induction, but induction time is most dependent on patient factors. Hospitals should focus on improving preparedness and limiting bias to create a more equitable and efficient perioperative process.

Abstract
BACKGROUND Socioeconomic status affects surgical outcomes, however these factors are not included in clinical quality improvement data and risk models. We performed a prospective registry analysis to determine if the Distressed Communities Index (DCI), a composite socioeconomic ranking by zip code, could predict risk-adjusted surgical outcomes and resource utilisation. METHODS All patients undergoing surgery (n=44,451) in a regional quality improvement database (American College of Surgeons-National Surgical Quality Improvement Program ACS-NSQIP) were paired with DCI, ranging from 0-100 (low to high distress) and accounting for unemployment, education level, poverty rate, median income, business growth and housing vacancies. The top quartile of distress was compared to the remainder of the cohort and a mixed effects modeling evaluated ACS-NSQIP risk-adjusted association between DCI and the primary outcomes of surgical complications and resource utilisation. RESULTS A total of 9369 (21.1%) patients came from severely distressed communities (DCI >75), who had higher rates of most medical comorbidities as well as transfer status (8.4% vs 4.8%, p<0.0001) resulting in higher ACS-NSQIP predicted risk of any complication (8.0% vs 7.1%, p<0.0001). Patients from severely distressed communities had increased 30-day mortality (1.8% vs 1.4%, p=0.01), postoperative complications (9.8% vs 8.5%, p<0.0001), hospital readmission (7.7 vs 6.8, p<0.0001) and resource utilisation. DCI was independently associated with postoperative complications (OR 1.07, 95% CI 1.04 to 1.10, p<0.0001) as well as resource utilisation after adjusting for ACS-NSQIP predicted risk CONCLUSION: Increasing Distressed Communities Index is associated with increased postoperative complications and resource utilisation even after ACS-NSQIP risk adjustment. These findings demonstrate a disparity in surgical outcomes based on community level socioeconomic factors, highlighting the continued need for public health innovation and policy initiatives.

Abstract
BACKGROUND The Accreditation Council for Graduate Medical Education Milestone Project for general surgery provided a more robust method for developing and tracking residents' competence. This framework enhanced systematic and progressive development of residents' competencies in surgical quality improvement. STUDY DESIGN A 22-month interactive, educational program based on resident-specific surgical outcomes data culminated in a quality improvement project for postgraduate year 4 surgery residents. Self- assessment, quality knowledge test, and resident-specific American College of Surgeons National Surgical Quality Improvement Program Quality In-Training Initiative morbidity were compared before and after the intervention. RESULTS Quality in-training initiative morbidity decreased from 25% (82/325) to 18% (93/517), p = 0.015 despite residents performing more complex cases. All participants achieved level 4 competency (4/4) within the general surgery milestones improvement of care, practice-based learning and improvement competency. Institutional American College of Surgeons National Surgical Quality Improvement Program general surgery morbidity improved from the ninth to the sixth decile. Quality assessment and improvement self-assessment postintervention scores (M = 23.80, SD = 4.97) were not significantly higher than preintervention scores (M = 19.20, SD = 5.26), p = 0.061. Quality Improvement Knowledge Application Tool postintervention test scores (M = 17.4, SD = 4.88), were not significantly higher than pretest scores (M = 13.2, SD = 1.92), p = 0.12. CONCLUSION Sharing validated resident-specific clinical data with participants was associated with improved surgical outcomes. Participating fourth year surgical residents achieved the highest score, a level 4, in the practice based learning and improvement competency of the improvement of care practice domain and observed significantly reduced surgical morbidity for cases in which they participated.

Abstract
BACKGROUND Pancreatic fistula remains a morbid complication after pancreatectomy. Since the proposed mechanism of pancreatic fistula is different between pancreaticoduodenectomy and distal pancreatectomy, we hypothesized that pancreatic gland texture and duct size are not associated with pancreatic fistula after distal pancreatectomy. METHODS All patients ≥18 years in the 2014-15 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) targeted pancreatectomy dataset were linked with the ACS NSQIP Public Use File (PUF). Pancreatic duct size (<3 mm, 3-6 mm, >6 mm) and pancreatic gland texture (hard, intermediate, soft) were categorized. Separate multivariable analyses were performed to evaluate associations between pancreatic duct size and gland texture after pancreaticoduodenectomy and distal pancreatectomy. RESULTS A total of 9366 patients underwent pancreaticoduodenectomy or distal pancreatectomy during the study period. Proportion of pancreatic fistula was similar after distal pancreatectomy (606 of 3132, 19.4%) and pancreaticoduodenectomy (1163 of 6335, 18.4%, p = 0.245). Both pancreatic gland texture and duct size were significantly associated with pancreatic fistula after pancreaticoduodenectomy (p<0.001). However, there was no association between pancreatic fistula and gland texture or duct size (all p≥0.169) after distal pancreatectomy. Operative approach (minimally invasive versus open) was not associated with pancreatic fistula after distal pancreatectomy (p = 0.626). Patients with pancreatic fistula after distal pancreatectomy had increased rate of postoperative complications including longer length of stay, higher rates of readmission and reoperation compared to patients who did not have a pancreatic fistula (all p<0.001). CONCLUSIONS Unlike among patients who had pancreaticoduodenectomy, pancreatic gland texture and duct size are not associated with development of pancreatic fistula following distal pancreatectomy. Other clinical factors should be considered in this patient population.

Abstract
BACKGROUND In North America, the prevalence of gastroesophageal reflux disorder ranges from 18.1% to 27.8%. We measured the risk posed by preoperative esophageal disease for patients undergoing abdominal operations. METHOD American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP; 2005-2015) data were merged with institutional clinical data repository records to identify esophageal disease in surgical patients undergoing intra-abdominal procedures. Patients with esophageal disease were classified as gastroesophageal reflux disorder (GERD) or other, which included patients with esophageal stricture, spasm, ulcer, or diverticuli, achalasia, esophagitis, reflux esophagitis, Barrett's esophagus, and multiple esophageal diagnoses, excluding GERD. ACS NSQIP-targeted procedure groups included were colectomy, proctectomy, ventral hernia repair, bariatric surgery, hepatectomy, appendectomy, abdominal aortic aneurysm repair, open aortoiliac repair, hysterectomy, myomectomy, and oophorectomy. Multivariable logistic regression was used to model postoperative complication rates, adjusting for ACS NSQIP risk of morbidity, demographic factors, ACS NSQIP-targeted procedure groups, and open versus laparoscopic surgery. RESULTS Of 9172 intra-abdominal cases, 21.3% had preoperative esophageal disease (19.6% GERD and 1.7% other). After adjustment, patients with GERD were at higher risk for experiencing a number of complications, including all-cause 30-d complication (odds ratio [OR] = 1.21, 95% confidence interval [CI] 1.05-1.41, P = 0.044), renal complication (OR = 1.43, 95% CI 1.09-1.87, P = 0.036), wound complication (OR = 1.40, 95% CI 1.10-1.79, P = 0.028), and readmission within 30 d (OR = 1.66, 95% CI 1.35-2.04, P < 0.001). CONCLUSIONS Preoperative GERD is associated with increased postoperative complication rate. Surgeons should consider assessing GERD in patients undergoing abdominal operations.

Abstract
BACKGROUND Acute kidney injury is a prevalent complication after abdominal surgery. With increasing adoption of enhanced recovery protocols, concern exists for concomitant increase in acute kidney injury. OBJECTIVE This study evaluated effects of enhanced recovery on acute kidney injury through identification of risk factors. DESIGN This was a retrospective cohort study comparing acute kidney injury rates before and after implementation of enhanced recovery protocol. SETTINGS The study was conducted at a large academic medical center. PATIENTS All of the patients undergoing elective colorectal surgery between 2010 and 2016, excluding patients with stage 5 chronic kidney disease, were included. MAIN OUTCOME MEASURES Patients before and after enhanced recovery implementation were compared, with rate of acute kidney injury as the primary outcome. Acute kidney injury was defined as a rise in serum creatinine ≥1.5 times baseline within 30 days of surgery. Multivariable logistic regression identified risk factors for acute kidney injury. RESULTS A total of 900 cases were identified, including 461 before and 439 after enhanced recovery; 114 cases were complicated by acute kidney injury, including 11.93% of patients before and 13.44% after implementation of enhanced recovery (p = 0.50). Five patients required hemodialysis, with 2 cases after protocol implementation. Multivariable logistic regression identified hypertension, functional status, ureteral stents, nonsteroidal anti-inflammatory drugs, operative time >200 minutes, and increased intravenous fluid administration on postoperative day 1 as predictors of acute kidney injury. Laparoscopic surgery decreased the risk of acute kidney injury. The enhanced recovery protocol was not independently associated with acute kidney injury. LIMITATIONS The study was limited by its retrospective and nonrandomized before-and-after design. CONCLUSIONS No difference in rates of acute kidney injury was detected before and after implementation of a colorectal enhanced recovery protocol. Independent predictors of acute kidney injury were identified and could be used to alter the protocol in high-risk patients. Future study is needed to determine whether protocol modifications will further decrease rates of acute kidney injury in this population. See Video Abstract at http://links.lww.com/DCR/A568.

Abstract
Medicare's Value-Based Purchasing Program (VBPP) compensates hospitals based on value of care provided. VBPP's total performance score (TPS) components data were evaluated by hospital groups: physician-owned surgical hospitals (POSH), Kaiser Hospitals, University HealthSystem Consortium Hospitals, Pioneer Accountable Care Organization Hospitals, US News and World Report Honor Roll Hospitals, and other hospitals. Multilevel random coefficient models estimated mean and significance of TPS differences from fiscal year (FY) 2015 and FY 2016, by hospital type. Overall mean TPS for 2985 hospitals decreased from 41.65 to 40.25. POSH and Kaiser Hospitals had significantly higher TPS in FY 2015 and FY 2016. POSH Patient Experience Domain scores exceeded all other Patient Experience Domain scores. The Efficiency Domain scores of Kaiser greatly exceeded the scores of all groups. Results suggest that POSH and Kaiser Hospitals provide significantly greater value of care with consistency from year to year when compared with other groups studied.

Abstract
BACKGROUND Safety of pancreaticoduodenectomy has improved significantly in the past 3 decades. Current inpatient and 30-d mortality rates are low. However, incidence and causes of 90-d and 1-y mortality are poorly defined and largely unexplored. METHODS All patients who had pancreaticoduodenectomy between 2007 and 2016 were included in this single institution, retrospective cohort study. Distributions of pancreaticoduodenectomy-specific morbidity and cause-specific mortality were compared between early (within 90 d) and late (91-365 d) postoperative recovery periods. RESULTS A total of 551 pancreaticoduodenectomies were performed during the study period. Of these, 6 (1.1%), 20 (3.6%), and 91 (16.5%) patients died within 30, 90, and 365 d after pancreaticoduodenectomy, respectively. Causes of early and late mortality varied significantly (all P ≤ 0.032). The most common cause of death within 90 d was due to multisystem organ failure from sepsis or aspiration in 9 (45%) patients, followed by post-pancreatectomy hemorrhage in 5 (25%) patients, and cardiopulmonary arrest from myocardial infarction or pulmonary embolus in 3 (15%) patients. In contrast, recurrent cancer was the most common cause of death in 46 (65%) patients during the late postoperative period between 91 and 365 d. Mortality from failure to thrive and debility was similar between early and late postoperative periods (15% versus 19.7%, P = 0.76). CONCLUSIONS Most quality improvement initiatives in patients selected for pancreaticoduodenectomy have focused on reduction of technical complications and improvement of early postoperative mortality. Further reduction in postoperative mortality after pancreaticoduodenectomy can be achieved by improving patient selection, mitigating postoperative malnutrition, and optimizing preoperative cancer staging and management strategies.

Abstract
Estimating surgeon-level value in health care remains relatively unexplored. American College of Surgeons National Surgical Quality Improvement Program Participant Use Files (2005-2013) were linked with total costs at a single institution. Random intercepts in 3-level random effects logistic regression models predicted 30-day postoperative mortality or morbidity for each surgeon each year. Value was defined as quality (morbidity or mortality) divided by costs for surgeons performing general surgery and vascular procedures. Forty-four surgeons performed 11 965 surgeries. Risk-adjusted costs trended down over time. For all surgeries, mortality value increased by 3.27 per year (95% confidence interval = 2.54-4.01; P < .001) on a 100-point scale, while morbidity value did not change. Of 21 surgeons with data for 5 years or longer, mortality value increased for all surgeons except one. Continuous increase in complication rates from 2008 contributed to decreased morbidity value. Value may assist surgeons in exploring performance opportunities better than morbidity or mortality alone.

Abstract
Adequate lymphadenectomy is associated with improved survival in patients who undergo oncologic resection of colorectal cancer and has been identified as a quality metric. Neoadjuvant chemotherapy has been found to be associated with collection of <12 lymph nodes in patients with rectal cancer. The purpose of this study was to evaluate patient and operative risk factors for inadequate lymph node retrieval during oncologic colectomy. The 2014 American College of Surgeons National Surgical Quality Improvement Program Participant Use File data set for oncologic colectomy (n = 9077) was analyzed. Patient- and operation-related factors were assessed by univariate and multivariate regression analyses to determine factors associated with the number of lymph nodes collected. Adequate lymphadenectomy was defined by collection of >12 lymph nodes. Of 9077 patients with a diagnosis of colon cancer who underwent colectomy, a minimum of 12 lymph nodes was harvested in 7897 (87%). Significant factors independently associated with inadequate lymphadenectomy included preoperative chemotherapy, emergent surgery, and T1 tumors (all P < 0.05). A large majority of patients who undergo colectomy for colon cancer have at least 12 lymph nodes collected. Preoperative chemotherapy is a major risk factor for inadequate lymph node retrieval. Recognition of factors associated with inadequate lymphadenectomy may improve colectomy lymph node yield and survival in patients with colon cancer.

Abstract
Adequate lymphadenectomy is associated with improved survival in patients who undergo oncologic resection of colorectal cancer and has been identified as a quality metric. Neoadjuvant chemotherapy has been found to be associated with collection of <12 lymph nodes in patients with rectal cancer. The purpose of this study was to evaluate patient and operative risk factors for inadequate lymph node retrieval during oncologic colectomy. The 2014 American College of Surgeons National Surgical Quality Improvement Program Participant Use File data set for oncologic colectomy (n = 9077) was analyzed. Patient- and operation-related factors were assessed by univariate and multivariate regression analyses to determine factors associated with the number of lymph nodes collected. Adequate lymphadenectomy was defined by collection of >12 lymph nodes. Of 9077 patients with a diagnosis of colon cancer who underwent colectomy, a minimum of 12 lymph nodes was harvested in 7897 (87%). Significant factors independently associated with inadequate lymphadenectomy included preoperative chemotherapy, emergent surgery, and T1 tumors (all P < 0.05). A large majority of patients who undergo colectomy for colon cancer have at least 12 lymph nodes collected. Preoperative chemotherapy is a major risk factor for inadequate lymph node retrieval. Recognition of factors associated with inadequate lymphadenectomy may improve colectomy lymph node yield and survival in patients with colon cancer.

Abstract
BACKGROUND Surgical site infection is a frequent cause of morbidity after colorectal resection and is a quality measure for hospitals and surgeons. In an effort to reduce the risk of postoperative infections, many wounds are left open at the time of surgery for secondary or delayed primary wound closure. OBJECTIVE The purpose of this study was to evaluate the impact of delayed wound closure on the rate of surgical infections and resource use. DESIGN This retrospective propensity-matched study compared colorectal surgery patients with wounds left open with a cohort of patients with primary skin closure. SETTINGS The American College of Surgeons National Quality Improvement Program Participant Use file for 2014 was queried. PATIENTS A total of 50,212 patients who underwent elective or emergent colectomy, proctectomy, and stoma creation were included. MAIN OUTCOME MEASURES Rates of postoperative infections and discharge to medical facilities were measured. RESULTS Surgical wounds were left open in 2.9% of colorectal cases (n = 1466). Patients with skin left open were broadly higher risk, as evidenced by a significantly higher median estimated probability of 30-day mortality (3.40% vs 0.45%; p < 0.0001). After propensity matching (n = 1382 per group), there were no significant differences between baseline characteristics. Within the matched cohort, there were no differences in the rates of 30-day mortality, deep or organ space infection, or sepsis (all p > 0.05). Resource use was higher for patients with incisions left open, including longer length of stay (11 vs 10 d; p = 0.006) and higher rates of discharge to a facility (34% vs 27%; p < 0.001). LIMITATIONS This study was limited by its retrospective design and a large data set with a bias toward academic institutions. CONCLUSIONS In a well-matched colorectal cohort, secondary or delayed wound closure eliminates superficial surgical infections, but there was no decrease in deep or organ space infections. In addition, attention should be given to the possibility for increased resource use associated with open surgical incisions. See Video Abstract at http://links.lww.com/DCR/A560.

Abstract
BACKGROUND Despite technical advances, bile leak remains a significant complication after hepatectomy. The current study uses a targeted multi-institutional dataset to characterize perioperative factors that are associated with bile leakage after hepatectomy to better understand the impact of bile leak on morbidity and mortality. METHODS Adult patients in the 2014-2015 ACS NSQIP targeted hepatectomy dataset were linked to the ACS NSQIP PUF dataset. Bivariable and multivariable regression analyses were used to assess the associations between clinical factors and post-hepatectomy bile leak. RESULTS Of 6859 patients, 530 (7.7%) had a postoperative bile leak. Proportion of bile leaks was significantly greater in patients after major compared to minor hepatectomy (12.6 vs. 5.1%, p < 0.001). The proportion of patients with bile leak was significantly greater in patients after major hepatectomy who had concomitant enterohepatic reconstruction (31.8 vs. 10.1%, p < 0.001). Postoperative mortality was significantly greater in patients with bile leaks (6.0 vs. 1.7%, p < 0.001). After adjusting for significant covariates, bile leak was independently associated with increased risk of postoperative morbidity (OR = 4.55; 95% CI 3.72-5.56; p < 0.001). After adjusting for significant effects of postoperative complications, liver failure, and reoperation (all p<0.001), bile leak was not independently associated with increased risk of postoperative mortality (p = 0.262). CONCLUSION Major hepatectomy and enterohepatic biliary reconstruction are associated with significantly greater rates of bile leak after liver resection. Bile leak is independently associated with significant postoperative morbidity. Mitigation of bile leak is critical in reducing morbidity and mortality after liver resection.

Abstract
BACKGROUND Following weight-loss surgery, patients who failed to achieve or sustain weight loss have nevertheless reported high satisfaction with their long-term bariatric experience. Understanding this phenomenon better will likely improve patients' experiences. OBJECTIVE The purpose of this study was to explore patients' long-term experiences following bariatric surgery. SETTING A 604-bed academic health system in the USA. METHODS Participants rated satisfaction and shared spontaneous comments regarding their gastric bypass experience. A phenomenological mode of inquiry explored participants' experiences. Transcribed phrases were categorized and themes identified. RESULTS In a 2004 surgical cohort, with 55% (155/281) participation, 99% of participants rated bariatric experience satisfaction (mean score 8.4) and 74% (115/155) shared comments regarding experiences. Responses were categorized as positive (63% 72/115), neutral (25% 29/115), or negative (12% 14/115). Satisfaction, Appreciation, and Gratefulness emerged as themes from positive comments, with 8% (6/72) explicitly acknowledging amount of weight loss achieved. Twenty-five percent (18/72) spontaneously mentioned undergoing surgery again or recommending the procedure to others. Neutral comments contained the themes of Reflection, Acknowledgment, and Wistfulness. Themes of Dissatisfaction, Disappointment, and Regret emerged from negative comments. Forty-three percent (6/14) of negative comments remarked on regaining weight or not reaching goal weight. Twenty-one percent (3/14) of negative comments explicitly stated regret at having undergone surgery. CONCLUSIONS Participants readily shared comments regarding their gastric bypass experience. Exploring themes provided insight into patients' satisfaction with bariatric surgery even when weight-loss goals were not met and conversely substantial dissatisfaction even when weight loss occurred. This study underscores the importance of understanding the patients' long-term experience following bariatric surgery.

Abstract
BACKGROUND This study aims to test associations between perioperative blood transfusion and postoperative morbidity and mortality after major abdominal operations. METHODS The 2014 ACS NSQIP dataset was queried for all patients who underwent one of the ten major abdominal operations. Separate multivariable regression models, were developed to evaluate the independent effects of perioperative blood transfusion on morbidity and mortality. RESULTS Of 48,854 patients in the study cohort, 4887 (10%) received a blood transfusion. Rates of transfusion ranged from 4% for laparoscopic gastrointestinal resection to 58% for open AAA. After adjusting for significant effects of NSQIP-estimated probabilities, transfusion was independently associated with morbidity and mortality after open AAA repair (OR = 1.99/14.4 respectively, p ≤ 0.010), esophagectomy (OR = 2.80/3.0, p < 0.001), pancreatectomy (OR = 1.88/3.01, p < 0.001), hepatectomy (OR = 2.82/5.78, p < 0.001), colectomy (OR = 2.15/3.17, p < 0.001), small bowel resection (OR = 2.81/3.83, p ≤ 0.004), and laparoscopic gastrointestinal operations (OR = 2.73/4.05, p < 0.001). CONCLUSIONS Perioperative blood transfusion is independently associated with an increased risk of morbidity and mortality after most major abdominal operations.

Abstract
Importance Given the current climate of outcomes-driven quality reporting, it is critical to appropriately risk stratify patients using standardized metrics. Objective To elucidate the risk associated with urgent surgery on complications and mortality after general surgical procedures. Design, Setting, and Participants This retrospective review used the American College of Surgeons National Surgery Quality Improvement Program database to capture all general surgery cases performed at 435 hospitals nationwide between January 1, 2013, and December 31, 2013. Data analysis was performed from November 11, 2015, to February 16, 2017. Exposures Any operations coded as both nonelective and nonemergency were designated into a novel category titled urgent. Main Outcomes and Measures The primary outcome was 30-day mortality; secondary outcomes included 30-day rates of complications, reoperation, and readmission in urgent cases compared with both elective and emergency cases. Results Of 173 643 patients undergoing general surgery (101 632 females and 72 011 males), 130 235 (75.0%) were categorized as elective, 22 592 (13.0%) as emergency, and 20 816 (12.0%) as nonelective and nonemergency. When controlling for standard American College of Surgeons National Surgery Quality Improvement Program preoperative risk factors, with elective surgery as the reference value, the 3 groups had significantly distinct odds ratios (ORs) of experiencing any complication (urgent surgery: OR, 1.38; 95% CI, 1.30-1.45; P < .001; and emergency surgery: OR, 1.65; 95% CI, 1.55-1.76; P < .001) and of mortality (urgent surgery: OR, 2.32; 95% CI, 2.00-2.68; P < .001; and emergency surgery: OR, 2.91; 95% CI, 2.48-3.41; P < .001). Surgical procedures performed urgently had a 12.3% rate of morbidity (n = 2560) and a 2.3% rate of mortality (n = 471). Conclusions and Relevance This study highlights the need for improved risk stratification on the basis of urgency because operations performed urgently have distinct rates of morbidity and mortality compared with procedures performed either electively or emergently. Because we tie quality outcomes to reimbursement, such a category should improve predictive models and more accurately reflect the quality and value of care provided by surgeons who do not have traditional elective practices.

Abstract
The University of Virginia (UVA) has recently become an Accountable Care Organization (ACO), intensifying efforts to provide better care for individuals. UVA's ACO population resides across the entire Commonwealth, with a large percentage of patients living in rural areas. To provide better health for this population, the central tenet of the ACO mission, we identified geographic risk factors influencing hospital readmission. We analyzed the relationship between the distance of patients’ residence to the nearest hospital and 30-day readmission in general surgery patients. A retrospective chart review using January 1, 2011 through October 31, 2013 American College of Surgeons National Surgical Quality Improvement Program data for general surgery procedures was conducted. ArcGIS mapped street addresses provided graphical representation of distance between surgical population and the nearest hospital. We analyzed the impact on readmission, of time traveled, insurance status, and median household income. Each increase of 10 minutes in travel time from the patient's residence to the nearest hospital, not just UVA, was associated with a 9 per cent increase in the probability of readmission after adjusting for patient characteristics, preoperative comorbidities, laboratory values, and postoperative complications before or after discharge (odds ratio = 1.09; 95% confidence interval = 1.01–1.17; P = 0.019). Unlike urban hospitals, those serving rural populations may be at particular risk of postsurgical readmissions. Patients living furthest from a hospital facility are most at risk for readmission after a general surgery procedure. This vulnerable population may benefit most from comprehensive discharge planning.

Abstract
BACKGROUND Morbidity after gastrectomy remains high. The potentially modifiable risk factors have not been well described. This study considers a series of potentially modifiable patient-specific and perioperative characteristics that could be considered to reduce morbidity and mortality after gastrectomy. METHODS This retrospective cohort study includes adults in the ACS NSQIP PUF dataset who underwent gastrectomy between 2011 and 2013. Sequential multivariable models were used to estimate effects of clinical covariates on study outcomes including morbidity, mortality, readmission, and reoperation. RESULTS Three thousand six hundred and seventy-eight patients underwent gastrectomy. A majority of patients had distal gastrectomy (N = 2,799, 76.1 %) and had resection for malignancy (N = 2,316, 63.0 %). Seven hundred and ninety-eight patients (21.7 %) experienced a major complication. Reoperation was required in 290 patients (7.9 %). Thirty-day mortality was 5.2 %. Age (OR = 1.01, 95 % CI = 1.01-1.02, p = 0.001), preoperative malnutrition (OR = 1.65, 95 % CI = 1.35-2.02, p < 0.001), total gastrectomy (OR = 1.63, 95 % CI = 1.31-2.03, p < 0.001), benign indication for resection (OR = 1.60, 95 % CI = 1.29-1.97, p < 0.001), blood transfusion (OR = 2.57, 95 % CI = 2.10-3.13, p < 0.001), and intraoperative placement of a feeding tubes (OR = 1.28, 95 % CI = 1.00-1.62, p = 0.047) were independently associated with increased risk of morbidity. Association between tobacco use and morbidity was statistically marginal (OR = 1.23, 95 % CI = 0.99-1.53, p = 0.064). All-cause postoperative morbidity had significant associations with reoperation, readmission, and mortality (all p < 0.001). CONCLUSIONS Mitigation of perioperative risk factors including smoking and malnutrition as well as identified operative considerations may improve outcomes after gastrectomy. Postoperative morbidity has the strongest association with other measures of poor outcome: reoperation, readmission, and mortality.

Abstract
BACKGROUND The Hospital Value-Based Purchasing Program measures value of care provided by participating Medicare hospitals and creates financial incentives for quality improvement and fosters increased transparency. Limited information is available comparing hospital performance across health care business models. STUDY DESIGN The 2015 Hospital Value-Based Purchasing Program results were used to examine hospital performance by business model. General linear modeling assessed differences in mean total performance score, hospital case mix index, and differences after adjustment for differences in hospital case mix index. RESULTS Of 3,089 hospitals with total performance scores, categories of representative health care business models included 104 physician-owned surgical hospitals, 111 University HealthSystem Consortium, 14 US News & World Report Honor Roll hospitals, 33 Kaiser Permanente, and 124 Pioneer accountable care organization affiliated hospitals. Estimated mean total performance scores for physician-owned surgical hospitals (64.4; 95% CI, 61.83-66.38) and Kaiser Permanente (60.79; 95% CI, 56.56-65.03) were significantly higher compared with all remaining hospitals, and University HealthSystem Consortium members (36.8; 95% CI, 34.51-39.17) performed below the mean (p < 0.0001). Significant differences in mean hospital case mix index included physician-owned surgical hospitals (mean 2.32; p < 0.0001), US News & World Report honorees (mean 2.24; p = 0.0140), and University HealthSystem Consortium members (mean 1.99; p < 0.0001), and Kaiser Permanente hospitals had lower case mix value (mean 1.54; p < 0.0001). Re-estimation of total performance scores did not change the original results after adjustment for differences in hospital case mix index. CONCLUSIONS The Hospital Value-Based Purchasing Program revealed superior hospital performance associated with business model. Closer inspection of high-value hospitals can guide value improvement and policy-making decisions for all Medicare Value-Based Purchasing Program Hospitals.

Abstract
BACKGROUND Effective collaboration among healthcare providers is an essential component of high-quality patient care. Interprofessional education is foundational to ensuring that students are prepared to engage in optimal collaboration once they enter clinical practice particularly in the care of complex geriatric patients undergoing surgery. STUDY DESIGN To enhance interprofessional education between nursing students and medical students in a clinical environment, we modeled the desired behavior and skills needed for interprofessional preoperative geriatric assessment for students, then provided an opportunity for students to practice skills in nurse/physician pairs on standardized patients. This experience culminated with students performing skills independently in a clinic setting. RESULTS Nine nursing students and six medical students completed the pilot project. At baseline and after the final clinic visit we administered a ten question geriatric assessment test. Post-test scores (M=90.33, SD=11.09) were significantly higher than pre-test scores (M=72.33, SD=12.66, t(14)=-4.50, p<0.001. Nursing student post-test scores improved a mean of 22.0 points and medical students a mean of 11.7 points over pre-test scores. Analysis of observational notes provided evidence of interprofessional education skills in the themes of shared problem solving, conflict resolution, recognition of patient needs, shared decision making, knowledge and development of one's professional role, communication, transfer of interprofessional learning, and identification of learning needs. CONCLUSIONS Having nursing and medical students "learn about, from and with each other" while conducting a preoperative geriatric assessment offered a unique collaborative educational experience for students that better prepares them to integrate into interdisciplinary clinic teams.

Abstract
BACKGROUND Congestive heart failure (CHF) predicts surgical morbidity and mortality. However, few studies evaluate CHF's impact on noncardiac operations. Because of CHFs serious threat to health and survival, surgeons must understand risks CHF poses to patients undergoing a diverse array of operations. STUDY DESIGN We used 2009 to 2013 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Participant Use Files to estimate the risk of serious morbidity, reoperation, readmission, mortality, and other postoperative complications associated with preoperative diagnosis of CHF. Multivariable logistic regression analysis provided odds ratios (OR) and 95% confidence intervals (CI) for outcomes in 34 ACS NSQIP procedure groups, controlling for age, sex, race, emergency surgery status, American Society of Anesthesiologists Classification, body mass index, and selected laboratory values. RESULTS Unadjusted ORs indicate adverse effects of CHF on surgical outcomes for most procedures considered. When adjusted for age and other confounders, CHF persists with adverse effects on most outcomes, including serious morbidity (OR 1.52, 95% CI, 1.44 to 1.61; p < 0.001); reoperation (OR 1.29, 95% CI, 1.17 to 1.42; p < 0.001); readmission (OR 1.39, 95% CI, 1.29 to 1.50; p < 0.001); and 30-day mortality (OR 1.96, 95% CI 1.80 to 2.13; p < 0.001). The impact of CHF on morbidity and mortality substantially affected those undergoing carotid endarterectomy and lower extremity endovascular repair. Cardiac arrest, mortality, unplanned intubation, and ventilator > 48 hours were complications most affected by CHF. CONCLUSIONS Congestive heart failure strongly predicts serious morbidity, unplanned reoperation, readmission, and surgical mortality for noncardiac operations. Surgeons must pay particular attention to recognizing CHF and optimizing perioperative management when considering surgery.

Abstract
BACKGROUND The long-term durability of Roux-en-Y gastric bypass (RYGB) remains ill-defined in the American population secondary to poor follow-up after bariatric surgery. OBJECTIVES This study evaluated the population lost to follow-up to better define the long-term durability of RYGB for weight loss and co-morbidity amelioration. METHODS All patients (n = 1087) undergoing RYGB at a single institution between 1985 and 2004 were evaluated. Univariate differences in preoperative co-morbidities, postoperative complications, annual weight loss, and 10-year co-morbidities were analyzed to compare outcomes between patients with routine follow-up and those without. Using electronic medical record review for all encounters at our academic medical center and telephone survey, we obtained data for patients lost to follow-up. RESULTS Among 1087 RYGB patients, 151 (14%) had consistent 10-year follow-up in our prospectively collected database, with yearly clinic visits beyond 2 years postoperatively. Electronic medical record review and telephone survey data were collected on an additional 500 (46%) patients, resulting in 60% of patients having 10-year follow-up after RYGB. There was no statistical difference in any preoperative or postoperative variables between the 2 groups. We found no difference in co-morbidity prevalence preoperatively or at 10 years between groups. Examination of percent excess body mass index lost at yearly intervals revealed no difference between the groups at each interval up to 10 years (P = .36). CONCLUSION We found no difference in 10-year outcomes, including weight loss and co-morbidity reduction, between patients with routine clinic visits and those lost to follow-up. These 10-year data address the gap in knowledge resulting from poor long-term follow-up after bariatric surgery.

Abstract
This study evaluates the risk of complications associated with elective laparoscopic adrenalectomy (LA) as reported in a national dataset. We hypothesize that the risk for major complication is associated with identifiable perioperative variables. This information may aid in understanding who safely could be discharged early after surgery, including same-day discharge. Elective LA from 2009 to 2010 American College of Surgeons National Surgical Quality Improvement Program Participant Use File were reviewed. A priori selection of likely risk factors for complications was assessed for their association with morbidity. Sequential bivariable logistic regression was used to measure the statistical significance of each risk factor's observed association with the occurrence of major morbidity after surgery. The potential for multiple comparisons bias was accounted for by using a high threshold ( P < 0.01) for identifying statistically significant associations. One thousand ninety-nine patients were identified. The 30-day mortality rate was 0.18 per cent, and 4.8 per cent of patients experienced a major morbidity within 30 days of surgery. Return to the operating room occurred in 1.46 per cent of cases. Statistically significant associations occurred for 15 patient characteristics at P < 0.05. Diabetes, nonindependent functional status before surgery, American Society of Anesthesiologists classification >2, and operative time were statistically significant at P < 0.01. Complications are rare events among elective LA patients. However, several readily identifiable patient characteristics are associated with the occurrence of complications among these patients. These patient characteristics should be taken into account when considering future trials of early discharge after LA, including same-day discharge.
