RESUMO
INTRODUCTION: Acute kidney injury (AKI) is a serious postoperative complication associated with increased morbidity and mortality. Identifying patients at risk for AKI is important for risk stratification and management. This study aimed to develop an AKI risk prediction model for colectomy and determine if the operative approach (laparoscopic versus open) alters the influence of predictive factors through an interaction term analysis. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was analyzed from 2005 to 2019. Patients undergoing laparoscopic and open colectomy were identified and propensity score matched. Multivariable logistic regression identified significant preoperative demographic, comorbidity, and laboratory value predictors of AKI. The predictive ability of a baseline model consisting of these variables was compared to a proposed model incorporating interaction terms between operative approach and predictor variables using the likelihood ratio test, c-statistic, and Brier score. Shapley Additive Explanations values assessed relative importance of significant predictors. RESULTS: 252,372 patients were included in the analysis. Significant AKI predictors were hypertension, age, sex, race, body mass index, smoking, diabetes, preoperative sepsis, Congestive heart failure, preoperative creatinine, preoperative albumin, and operative approach (P < 0.001). The proposed model with interaction terms had improved predictive ability per the likelihood ratio test (P < 0.05) but had no statistically significant interaction terms. C-statistic and Brier scores did not improve. Shapley Additive Explanations analysis showed hypertension had the highest importance. The importance of age and diabetes showed some variation between operative approaches. CONCLUSIONS: While the inclusion of interaction terms collectively improved AKI prediction, no individual operative approach interaction terms were significant. Including operative approach interactions may enhance predictive ability of AKI risk models for colectomy.

INTRODUCTION: Patients are increasingly utilizing social media to help them make medical decisions. Previous studies have examined Facebook for the quality of bariatric-related content; however, no research has examined Twitter, a globally favored platform, in this context. The goal of this study is to investigate the quality of bariatric-related content on Twitter that patients use to inform their decisions regarding bariatric surgery. METHODS: Six comprehensive terms were searched on six Twitter accounts for 4 wk. Each keyword generated corresponding tweets that were classified as being either informational or noninformational. The top ten informational posts for each search term were categorized based on content type, tweet posters, and type of evidence used. A DISCERN score was calculated for each tweet to determine its quality of consumer health information. RESULTS: A total of 7531 tweets about bariatric surgery were collected over the course of approximately 1 mo. We found that 58.9% of tweets pertained to surgical interventions, 16.2% were nutrition-related, 11.3% were progress posts, 7.8% were inspirational posts, and 5.9% pertained to lifestyle. Of the tweets pertaining to surgical interventions, 26% were posted by physicians, and 13.7% of those physicians used scientific evidence. The relationship between the average total DISCERN scores and each variable was statistically significant. CONCLUSIONS: Even though physicians posted the highest quality consumer information, that information still correlated with an average DISCERN score of "very poor". Twitter may provide a good way to foster community and get anecdotal information but is not a place to gather high-quality scientific consumer health information.

INTRODUCTION: Bowel obstruction is one of the most common surgical emergencies. The management of SBO is variable and influenced by numerous confounding factors. Recent studies have identified mental health as a health disparity that affects surgical outcomes. We aim to assess whether mental illness is a health disparity and its association with postoperative complications and secondary outcomes for bowel obstruction in Emergency General Surgery (EGS). METHODS: This was a retrospective study utilizing the National Inpatient Sample. Individuals aged 18-64 who underwent emergency adehesiolysis or bowel resection from 2015 to 2017 were identified. Postoperative complications, in-hospital mortality, length of stay, and total cost for surgical patients with and without mental illness were recorded. Univariate and multivariate analyses were used to evaluate the association between mental health and bowel obstruction. RESULTS: 20,574 patients who underwent surgery for bowel obstruction were identified. 3756 of these patients had mental illness and 16,998 patients did not. Patients with mental illness did not have significantly worse outcomes compared to patients without mental illness. Among 3576 patients with mental illness, sex, race, patient location, insurance, location/teaching status of hospital, hospital control and procedure type were significant predictors of prolonged length of stay, higher cost, and increased postoperative complications. CONCLUSIONS: Mental health does not appear to be a health disparity in outcomes for bowel obstruction procedures. However, the intersection of mental health with race and insurance status predicts worse outcomes. This essential area should be further explored to determine how marginalized populations are affected in emergency surgical care.

INTRODUCTION: Emergency general surgery (EGS) patients often present with anemia, in which preoperative transfusions are performed to mitigate anemia-associated risks. However, transfusions have also been noted to cause worse postoperative outcomes. This study examined how transfusion-associated outcomes vary at different levels of anemia. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2019 was used to identify patients who had undergone any of 12 major EGS procedures using Current Procedural Terminology codes. Patients were divided into two cohorts based on receipt of preoperative transfusion. Cohorts were subdivided into anemia severity levels and propensity score-matched within each using patient demographic and comorbidity variables. We analyzed 30-day postoperative outcomes, including morbidity, mortality, and return to odds ratio (OR), using univariate Chi-squared tests, Wilcoxon signed-rank tests, and multivariate logistic regression analyses. RESULTS: 595,407 EGS cases were identified. Receiving preoperative transfusion were 44.45% (n = 3058) of severely anemic, 10.94% (n = 9076) of moderately anemic, 1.34% (n = 1370) of mildly anemic, and 0.174% (n = 704) of no anemia patients. Transfusion resulted in an increased overall morbidity in the severe (OR 1.54), moderate (OR 1.50), mild (OR 1.71), and no anemia (OR 1.85) groups. Mortality increased in the moderate (OR 1.27), mild (OR 1.61), and no anemia (OR 1.76) subgroups. In severe anemia, transfusion status and mortality were not significantly associated. CONCLUSIONS: Transfusion is associated with higher morbidity and mortality rates in those with higher hematocrit levels, even after controlling for pre-existing comorbidities. A restrictive transfusion strategy should be considered to avoid risks for those with a hematocrit level more than 24%.

INTRODUCTION: A laparoscopic approach to bariatric surgeries confers a favorable side-effect profile as compared to an open approach. However, literature regarding the independent association of race with access to and postoperative outcomes in laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (GS) is scarce. MATERIALS AND METHODS: All RYGB and GS cases recorded in American College of Surgeons National Quality Improvement Program data from 2012 to 2020 were subjected to propensity score matching to assess the independent association between Black self-identified race on access to a laparoscopic approach and postoperative complications. Finally, a series of logistic regressions enabled evaluation of the mediating effect of operative approach on racial disparities in postoperative complications. RESULTS: 55,846 cases of RYGB and 94,209 cases of GS were identified. Following propensity score matching, logistic regression identified Black race as an independent predictor of open approach to RYGB (P < 0.001) and GS (P = 0.019). Black patients had increased incidence of any, minor and severe postoperative complications and unplanned readmissions in both RYGB (P < 0.001, P < 0.001, P = 0.0412, and P < 0.001, respectively) and GS (P < 0.001, P < 0.001, P = 0.0037, and P < 0.001, respectively). Open approach to RYGB was identified as a partial mediator of the independent association between Black race and any complication, minor complications, and unplanned readmission. CONCLUSIONS: This methodology identified racial disparities in complications following RYGB and GS. Interestingly, reduced access to a laparoscopic approach mediated racial disparities in complications following RYGB but not GS. Further research might elucidate upstream determinants of health that catalyze these disparities.

BACKGROUND: Surgical resection is a mainstay of treatment for colorectal cancer (CRC). Minimally invasive surgery (MIS) has been shown to have improved outcomes compared to open procedures for colorectal malignancy. While use of MIS has been increasing, there remains large variability in its implementation at the hospital and patient level. OBJECTIVE: The purpose of this study was to identify disparities in sex, race, location, patient income status, insurance status, hospital region, bed size and teaching status for the use of MIS in the treatment of CRC. METHODS: This was a retrospective cohort study using the Nationwide Inpatient Sample Database. Between 2008 and 2017, there were 412,292 hospitalizations of adult patients undergoing elective colectomy for CRC. The primary outcome was use of MIS during hospitalization. RESULTS: Overall, the frequency of open colectomies was higher than MIS (56.56% vs. 43.44%). Black patients were associated with decreased odds of MIS use during hospitalization compared to White patients (OR 0.921, p = 0.0011). As the county population where patients resided decreased, odds of MIS also significantly decreased as compared to central counties of metropolitan areas. As income decreased below the reference of $71,000, odds of MIS also significantly decreased. Medicaid and uninsured patients had decreased odds of MIS use during hospitalization compared to private insurance (OR 0.751, p < 0.0001 and OR 0.629, p < 0.0001 respectively). Rural and urban non-teaching hospitals were associated with decreased odds of MIS as compared to urban teaching hospitals (OR 0.523, p < 0.0001 and OR 0.837, p < 0.0001 respectively). Hospitals with a small bed size were also associated with decreased MIS during hospitalizations (OR 0.888, p < 0.0001). CONCLUSIONS: Marked hospital level and socioeconomic disparities exist for utilization of MIS for colorectal cancer. Strategies targeted at reducing these gaps have the potential to improve surgical outcomes and cancer survival.

BACKGROUND: Esophageal cancer and gastric cancer are two important causes of upper GI malignancies. Literature has shown that minimally invasive esophagectomies (MIE) and gastrectomies (MIG), have shorter length of stay and fewer complications. However, limited literature exists about the association between race and access to MIE and MIG. This study aims to identify the racial disparities in the different approaches to esophagectomy and gastrectomy. We further evaluate the relationship between the race and postoperative complications. METHODS: This IRB-approved retrospective study utilized data from the American College of Surgeons National Quality Improvement Program. All recorded cases of MIE, MIG, open gastrectomy, and esophagectomy between 2012 and 2019 were isolated. Propensity score matching and univariate analysis was performed to assess the independent effect of black self-identified race on access and outcomes. p < 0.05 was required to achieve statistical significance. RESULTS: 7891 cases of esophagectomy and 5,132 cases of gastrectomy cases were identified. Using Propensity and logistic regression, we identified that black self-reported race is an independent predictor of open approach to gastrectomy (OR 1.6871943, 95% CI 1.431464-1.989829, p < 0.001). Black self-reported race was not predictive of operative approach among esophagectomy patients (OR 0.7942576, 95% CI 0.5698645-1.124228, p = 0.183). In contrast, black self-reported is an independent predictor of postoperative complications among esophagectomy patients only. Esophagectomy patients of black self-reported race were more likely to experience any complication (OR 1.4373437, 95% CI 1.1129239-1.8557096, p = 0.00537), severe complications (OR 1.3818966, 95% CI 1.0653087-1.7888454, p = 0.0144), and death (OR 2.00779762, 95% CI 1.08034921-3.56117535, p = 0.0211) within 30 days of their surgeries. CONCLUSION: Our analysis revealed a significant racial disparity in access to MIG and a higher incidence of post-operative complications amongst esophagectomy patients. Minimally invasive techniques are underutilized in racial minorities. The findings herein warrant further investigation to eliminate barriers and disparities.

STUDY OBJECTIVE: To identify racial and socioeconomic disparities in the surgical management of ectopic pregnancy. DESIGN: Retrospective study. The National Inpatient Sample was sampled from 2015 to 2017 for inpatient hospitalizations for ectopic pregnancy. Cohorts were identified by surgical treatment type-open procedure vs laparoscopic procedure. Race/ethnicity, primary payer status, and median household income were primary variables of interest. Univariate and multivariable analyses were conducted. SETTING: Nationwide inpatient analysis. PATIENTS: Women presenting for ectopic pregnancy treatment. INTERVENTIONS: Type of surgery. MEASUREMENTS AND MAIN RESULTS: Outcome measures were laparotomy vs laparoscopy for treatment. A total of 18 725 cases were identified, 8325 open and 10 400 laparoscopic. Hispanic women were more likely to receive open procedures as treatment for ectopic pregnancy than White women (odds ratio 1.226, p <.001). Women with private insurance were more likely to receive open procedures than women who used self-pay for treatment (odds ratio 0.809, p <.001). Women of lower median income status, <$60 000, were more likely to receive open procedures than women of the fourth quartile income group. Black women predominantly made up the first quartile income group. When controlling for covariates, Black women were not more likely to receive 1 method of surgical procedure over another. CONCLUSION: Income appears to be related to surgical management of ectopic pregnancy with women of lower median incomes receiving laparotomies over laparoscopic procedures. Equal access to healthcare remains a prudent need in communities of color. Further studies are needed to elucidate surgical decision-making in the management of ectopic pregnancy.

BACKGROUND: Inguinal hernia repair is one of the most commonly performed surgical procedures. We developed and validated an artificial neural network (ANN) model for the prediction of surgical outcomes and the analysis of risk factors for inguinal hernia repair. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program was used to find patients who underwent inguinal hernia repair. Using logistic regression and ANN models, we evaluated morbidity, readmission, and mortality using the area under the receiver operating characteristic curves, true-positive rate, true-negative rate, false-positive rate, and false-negative rates. RESULTS: There was no significant difference in the power of the ANN and logistic regression for predicting mortality, readmission, and all morbidities after inguinal hernia repair. Risk factors for morbidity, readmission, and mortality outcomes identified using ANN were consistent with logistic regression analysis. CONCLUSIONS: ANNs perform comparably to logistic regression models in the prediction of outcomes after inguinal hernia repair. ANNs may be a useful tool in risk factor analysis of hernia surgery and clinical applications.

BACKGROUND: Emergency general surgery (EGS) has high rates of morbidity, mortality, and readmission. Therefore, it might be expected that an EGS service fields many consultations for postoperative patients. However, with the known overutilization of emergency department visits for nonurgent conditions, we hypothesized most postoperative consults received by an EGS service would be nonurgent and could be appropriately managed as an outpatient. METHODS: We reviewed all EGS consults at a single urban safety net hospital over a 12-month period, screening for patients who had undergone surgery in the previous 12 mo. This included consultations from the emergency room and inpatient setting. Demographics, admission status, procedures performed, and other details were abstracted from the chart and Vizient reports. Consultation questions were categorized and then reviewed by an expert panel to determine if conditions could have been managed as an outpatient. RESULTS: The EGS service received a total of 1112 consults, with 99 (9%) for a postoperative condition. Overall, 85% of postoperative consults were admitted after consultation, 19% underwent surgery and 21% underwent a procedure with gastroenterology or interventional radiology. Expert review classified slightly over one-third (36%) of consults as nonurgent. CONCLUSIONS: Most postoperative consults seen at our urban safety net hospital represent true morbidity that required admission, intervention, or surgery. Despite this high acuity, one-third of postoperative consults could have been managed as an outpatient. Efforts to improve discharge instructions and set patient expectations could limit unnecessary postoperative emergency department visits.

BACKGROUND: Deep vein thromboses (DVTs) are a significant sequela of surgery and are associated with significant of morbidity and mortality in the United States. Operative emergency general surgery (EGS) cases have been demonstrated to have a greater burden of DVT than other types of surgery. MATERIALS AND METHODS: DVT in EGS cases were identified from the National Inpatient Sample-Healthcare Cost and Utilization Project database from 2001 to 2015 Q3 based on ICD-9 code specification. National incidence of DVT in EGS was calculated using the National Inpatient Sample-Healthcare Cost and Utilization Project sampling methodology, and propensity score matching was used to assess costs associated with DVT. RESULTS: Among 15,148,352 sample-weighted hospitalizations, 0.623% (94,392) experienced DVT. Incidence of DVT was greatest in GI ulcer surgery (1.705%) and lowest in appendectomy (0.095%). Patients with a perioperative DVT incurred $22,301 more in hospital-related costs than their counterparts who did not have a DVT. Although rates of DVT remained stable over the period analyzed, DVT-associated costs increased at a 2.09% annual rate in excess of inflation during the period analyzed. This increase in costs was most significant for laparotomy, which increased at a rate of 8.09% annually. CONCLUSIONS: DVT continues to be a significant burden on resources in EGS in spite of efforts with DVT prophylaxis. Considering the increase in costs and little change in incidence, further research on cost-effective management of DVT in EGS is warranted.

BACKGROUND: Current studies suggest that laparoscopic colorectal surgery is an advantageous alternative to open surgery due to improved post-operative outcomes in high-risk patient groups. Limited data is currently available on the benefits of minimally invasive colectomy for diverticulitis in patients with significant pre-operative respiratory comorbidities. STUDY DESIGN: The NSQIP 2005-2017 datasets were used to identify patients that underwent partial colectomies due to diverticulitis. Partial colectomy cases were identified using CPT codes and then filtered to include only ICD 9 and 10 codes for diverticulitis. Pre-operative respiratory comorbidities included dyspnea, chronic obstructive pulmonary disease (COPD), and smoking status. Propensity matching was performed based on patient demographic and pre-operative risk factor data to create comparable groups for each respiratory comorbidity subset. Outcomes of interest were 30-day post-operative mortality and morbidity, incidence of return to operating room (ROR), and hospital length of stay (LoS). Laparoscopy and open surgery groups were compared using Chi square tests for categorical variables and t tests for continuous variables. A p value less than 0.05 was considered statistically significant. RESULTS: Among 70,420 cases with diverticulitis, 15,237 cases were identified as smokers, 3934 had dyspnea, and 3219 had COPD. Patients that had open procedures had significantly greater odds of mortality (OR 2.624 for smokers; OR 2.698 for dyspnea; OR 2.663 for COPD), morbidity (OR 2.590 for smokers; OR 2.344 for dyspnea; OR 2.883 for COPD), wound complication (OR 1.989 for smokers; OR 1.461 for dyspnea; OR 1.956 for COPD), and ROR (OR 1.184 for smokers; OR 1.634 for dyspnea; OR 1.975 for COPD). Laparoscopic procedures resulted in significantly lower average LoS (5.34 vs. 9.46 days for smokers; 6.84 vs. 11.06 days for dyspnea; 7.41 vs. 12.62 days for COPD; all p < .0001). CONCLUSION: Laparoscopic colectomy for diverticulitis diagnosis for a matched cohort of patients with pre-operative respiratory comorbidities such as smoking status, dyspnea, and COPD resulted in significantly improved post-operative outcomes, lower odds of mortality and morbidity, and shorter LoS.

BACKGROUND: Solid organ transplant has been identified as an independent risk factor in ventral hernia repair. Previous studies have generally focused on case studies or small samples. We sought to investigate the impact of liver or kidney transplant on ventral hernia repair outcomes using a nationally representative sample. METHODS: The National Inpatient Sample was used to identify ventral hernia repairs from years 2005 to 2014. We then divided them into two groups, patients with prior solid organ transplant and those without, and used logistic regression to analyze the effect of this variable on outcomes. We then investigated the relationship between various comorbidities and 30-d outcomes of surgery in both groups after adjusting for comorbidities. The primary outcome we looked at was mortality, with secondary outcomes such as length of stay and various surgical complications. RESULTS: We compared two groups consisting of patients with prior transplant (n = 3317) and patients without (n = 372,775) and found that patients with prior liver or kidney transplant did not have higher mortality rates and also did not have longer lengths of stay. In addition, in terms of preoperative variables, patients with transplant were more likely to have the following comorbidities: cardiac arrhythmia, chronic blood loss anemia, chronic pulmonary disease, congestive heart failure, depression, metastatic cancer, obesity, psychoses, solid tumor without metastasis, and weight loss. Diabetes was associated with higher mortality in transplant patients. CONCLUSIONS: Patients without prior liver or kidney transplant did not have higher mortality rates or lengths of stay.

BACKGROUND: Most closed clavicle fractures are treated nonoperatively. Research during the past decade has reported differences in the treatment of clavicle fractures based on insurance status in the US and may highlight unmet needs in a vulnerable population, particularly because new data show that surgery may lead to improved outcomes in select populations. Large-scale, national data are needed to better inform this debate. QUESTIONS/PURPOSES: (1) Does the likelihood of operative fixation of closed clavicle fractures vary among patients with different types of insurance? (2) What demographic and socioeconomic factors are associated with the likelihood of clavicle fracture surgery? (3) Has the proportion of operative fixation of clavicle fractures changed over time? METHODS: A retrospective analysis of the Nationwide Inpatient Sample 2001-2013 database was performed. This database is the largest publicly available all-payer inpatient database in the US that provides pertinent socioeconomic data on a nationwide scale. Data were queried for patients with closed clavicle fractures using International Classification of Diseases, Ninth Revision (ICD-9) diagnostic codes, and surgery was determined using ICD-9 procedural codes. A total of 252,109 patients were included in the final analysis after 158,619 patients were excluded because of missing demographic or insurance data, ambiguous fracture location, or age younger than 19 years. Of the 252,109 included patients, 21,638 (9%) underwent surgical fixation of clavicle fractures. A chi-square analysis was performed to determine variables to be included in a multivariable analysis. A binary logistic regression analysis was used to examine demographic and other important variables, with a significance level of p < 0.01. Poisson's regression and a t-test were used to analyze trends over time. Results were recorded as odds ratios (OR) and incidence rate ratios. RESULTS: After controlling for demographic and potentially relevant variables, such as the median income and fracture location, we found that patients with Medicare, Medicaid, and no insurance had a lower likelihood of undergoing operative fixation of clavicle fractures than did those with private insurance. Patients without insurance were the least likely to undergo surgery (OR, 0.63; 95% CI, 0.60-0.66; p < 0.001), followed by those with Medicare (OR, 0.73; 95% CI, 0.70-0.78; p < 0.001) and those with Medicaid (OR, 0.74; 95% CI, 0.69-0.78; p < 0.001). Women, black, and Hispanic patients were also less likely to undergo surgery than men and white patients (OR, 0.95; p = 0.003; OR = 0.67; p < 0.001; and OR = 0.82; p < 0.001, respectively) There was an increase in the overall proportion of patients undergoing surgery, from 5% in 2001 to 11% in 2013 (incidence rate ratio, 2.99; p < 0.001). CONCLUSIONS: We believe that the greater use of surgery among adult patients with clavicle fractures who have private insurance than among those with nonprivate or no insurance-as well as among men and white patients compared with women and patients of color-may be a manifestation of important health care disparities in the inpatient population. This may be owing to variable access to care or a difference in the likelihood that a surgeon will offer surgery based on a patient's insurance status. Because operative fixation of closed clavicle fractures increases in the adult population, future research should elucidate conscious and subconscious motivations of patients and surgeons to better inform the discussion of health care disparities in orthopaedics. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Small bowel obstruction (SBO) continues to be a common indication for acute care surgery. While open procedures are still widely used for treatment, laparoscopic procedures may have important advantages in certain patient populations. We aim to analyze differences in outcomes between the two for treatment of bowel obstruction. METHODS: The American College of Surgeons National Surgical Quality Improvement Program was used to find patients that underwent emergent or non-elective surgery for SBO. Propensity matching was used to create comparable groups. Logistic regression was used to assess differences in the primary outcome of interest, return to operating room, and morbidity and mortality outcomes. Logistic regression was also used to assess the contribution of various preoperative demographic and comorbidity characteristics to 30-day mortality. RESULTS: A total of 24,028 patients underwent surgery for SBO from 2005 to 2011. Of those, 3391 were laparoscopic. Propensity matching resulted in 6782 matched patients. Laparoscopic cases had significantly decreased odds of experiencing any morbidity and wound complications compared to open cases in bowel-resection and adhesiolysis-only cases. There was no significant difference found for odds of returning to operating room. Laparoscopic cases resulted in significantly shorter hospital stays than open cases (7.18 vs.10.84 days, p < 0.0001). Increasing age, American Society of Anesthesiologists class greater than three, and the presence of respiratory comorbidities resulted in increased odds of mortality. Underweight body mass index (BMI) (< 18.5) increased odds of mortality while greater than normal BMI (> 25) decreased odds of mortality. CONCLUSIONS: Analysis of emergent SBO cases between 2005 and 2015 demonstrates that laparoscopy is not utilized as often as open approaches in surgical treatment. Laparoscopic surgery resulted in reduced postoperative morbidity and significantly shorter hospital stays compared to open intervention and was not associated with significant differences in odds of reoperation compared to open surgery.

BACKGROUND: Socioeconomic factors such as race, insurance, and income quartiles have been identified as independent risk factors in emergency general surgery (EGS), but this impact has not been studied over time. We sought to identify trends in disparities in EGS-related operative mortality over a 20-y period. METHODS: The National Inpatient Sample was used to identify patient encounters coded for EGS in 1993, 2003, and 2013. Logistic regression models were used to examine the adjusted relationship between race, primary payer status, and median income quartiles and in-hospital mortality after adjusting for patients' age, gender, Elixhauser comorbidity score, and hospital region, size, and location-cum-teaching status. RESULTS: We identified 391,040 patient encounters. In 1993, Black race was associated with higher odds of in-hospital mortality (odds ratio [95% confidence interval]: 1.35 [1.20-1.53]) than White race, although this difference dissipated in subsequent years. Medicare, Medicaid, and underinsured patients had a higher odds of mortality than those with private insurance for the entire 20-y period; only the disparity in the underinsured decreased over time (1993, 1.63 [1.35-1.98]; 2013, 1.41 [1.20-1.67]). In 2003 (1.23 [1.10-1.38]) and 2013 (1.23 [1.11-1.37]), patients from the lowest income quartile were more likely to die after EGS than patients from the highest income quartile. CONCLUSIONS: Socioeconomic disparities in EGS-related operative morality followed inconsistent trends. Over time, while gaps in in-hospital mortality among Blacks and Whites have narrowed, disparities among patients belonging to lowest income quartile have worsened. Medicare and Medicaid beneficiaries continued to experience higher odds of in-hospital mortality relative to those with private insurance.

BACKGROUND: In a parallel demographic phenomenon, the elderly and obese populations will become a larger part of our population and surgical practices. The elderly obese surgical risk profile is not clearly defined, although studies have confirmed their independent negative effect on surgical outcomes. Benign foregut surgery is a relatively common complex procedure performed on this demographic and warrants deeper investigation into outcomes. We investigate the synergistic effect of age and body mass index (BMI) on the outcomes of benign foregut surgery. METHODS: Data from National Surgical Quality Improvement Program were collected for all patients undergoing foregut surgery from 2005 to 2012. Subjects were over 18 years of age and 16 BMI. Primary and secondary outcomes were 30-day mortality and overall 30-day morbidity, respectfully. Binary logistic regression models were used to assess independent and interactive effects of age and BMI. RESULTS: A total of 19,547 patients had an average age and BMI of 57 and 29.7, respectively. Sample 30-day mortality was 0.32 %. Every 10-year age increase led to a 46 % increased odds of mortality. BMI showed a bimodal distribution with underweight and morbidly obese patients having increased mortality. The effect of BMI only became apparent with increasing age. CONCLUSIONS: Both age and BMI are independent predictors of mortality; only older patients experienced the bimodal BMI effect. Therefore, increasing age and BMI have a synergistic effect on outcomes after foregut operations.

BACKGROUND: The American Board of Surgery will require graduating surgical residents to achieve proficiency in endoscopy. Surgical simulation can help residents to prepare for this proficiency test, accelerate skill acquisition, shorten the learning, and improve patient safety. Currently, endoscopic simulators are extremely cost-prohibitive. We therefore designed an inexpensive physical endoscopic simulator to (1) facilitate Fundamentals of Endoscopic Surgery skills training and (2) teach basic colonoscopy skills, for <$200.00. METHODS: We constructed the Rutgers Open Source Colonoscopy Simulator (ROSCO) from easily acquired commercial materials. For construct validation, we compared novices to experts in a two-arm non-randomized study. Each participant performed the five tasks and a full cecal intubation on the simulator. Face and content validity surveys were taken by the experts, after the construct validity study to determine the simulator's ability to achieve the intended task with "realism." Data were collected on (1) cost and construction, (2) time to completion of individual tasks, (3) percentage of task completion, and (4) survey statistics. RESULTS: Our simulator requires no advanced expertise, costs $62.77 US, and weighs 8.5 pounds. The ROSCO simulator was clearly able to distinguish expert from novice. Expert task times for completing all five tasks, performing the loop reduction, and reaching the splenic and hepatic flexures on the simulator were significantly better than novice times (p < 0.05). All participants were able to complete all five tasks on the simulator 100 % of the time. Three out of five experts "Agreed" or "Strongly Agreed" with five out of the six statements regarding the simulator's teaching ability. Four out of five experts rated each of the five specific aspects of the simulator as "Realistic" or "Very Realistic." CONCLUSIONS: We have designed a low-cost colonoscopy simulator with easily available materials and which requires very little advanced construction expertise and have demonstrated construct, face, and content validity. We believe this will have broad impact for endoscopic simulation, surgical education, and health education cost.

BACKGROUND: The ACS-NSQIP Surgical Risk Calculator (SRC) is used to predict surgical outcomes, but its accuracy in gastrectomy has been questioned.1,2 We investigated if adding hypoalbuminemia enhances its predictive ability in gastrectomy. METHODS: We identified gastrectomy patients from the ACS-NSQIP database from 2005 to 2019. We constructed pairs of logistic regression models: one with the existing 21 preoperative risk factors from the SRC and another with the addition of hypoalbuminemia. We evaluated improvement using Likelihood Ratio Test (LRT), Brier scores, and c-statistics. RESULTS: Of 18,070 gastrectomy patients, 34.5 â% had hypoalbuminemia. Hypoalbuminemia patients had 2.34 higher odds of mortality and 1.79 higher odds of morbidity. Adding hypoalbuminemia to the RC model statistically improved predictions for mortality, cumulative morbidity, pulmonary, renal, and wound complications (LRT p â< â0.001). It did not improve predictions for cardiac complications (LRT p â= â0.11) CONCLUSION: Hypoalbuminemia should be considered as an additional variable to the ACS-NSQIP SRC for gastrectomy.

Background: Ventriculoperitoneal shunt (VPS) can be placed solely by a neurosurgeon often via an open-laparotomy approach, or laparoscopically as a collaborative effort between a neurosurgeon and a general surgeon. Prior studies have shown conflicting results when examining outcomes regarding infection, revision rate, hospital charges, length of stay, and mortality between the open mini-laparotomy and the laparoscopic approaches. Objective: The current study uses the National Inpatient Sample (NIS) to compare outcomes of open mini-laparotomy vs. laparoscopic collaborative approach in VPS placement. Methods: We performed a retrospective database study of the NIS from October 2015-December 2017 utilizing International Classification of Diseases, 10th Revision coding to identify all cases of VPS placement. All analyses accounted for the sampling design of the NIS. Results: A total of 6580 cases (4969 with open mini-laparotomy approach and 1611 with laparoscopic collaborative approach) met inclusion criteria. Hospital charges, infection rates, and revision rates were similar between approaches. There were no significant differences in length of stay, mortality, or complication rates between the two approaches. Conclusion: The collaborative, laparoscopic approach to VPS placement has similar outcomes and is non-inferior to the traditional open mini-laparotomy approach.
