History of Equity, Diversity, and Inclusion in Trauma Surgery: for Our Patients, for Our Profession, and for Ourselves.

Purpose of Review: Disparities exist in outcome after injury, particularly related to race, ethnicity, socioeconomics, geography, and age. The mechanisms for this outcome disparity continue to be investigated. As trauma care providers, we are challenged to be mindful of and mitigate the impact of these disparities so that all patients realize the same opportunities for recovery. As surgeons, we also have varied professional experiences and opportunities for achievement and advancement depending upon our gender, ethnicity, race, religion, and sexual orientation. Even within a profession associated with relative affluence, socioeconomic status conveys different professional opportunities for surgeons. Recent Findings: Fortunately, the profession of trauma surgery has undergone significant progress in raising awareness of patient and professional inequity among trauma patients and surgeons and has implemented systematic changes to diminish these inequities. Herein we will discuss the history of equity and inclusion in trauma surgery as it has affected our patients, our profession, and our individual selves. Summary: Our goal is to provide a historical context, a status report, and a list of key initiatives or objectives on which all of us must focus. In doing so, the best possible clinical outcomes can be achieved for patients and the best professional and personal "outcomes" can be achieved for practicing and future trauma surgeons.

High Resource Utilization in Emergent Versus Elective General Surgery.

BACKGROUND: In an era of pay for performance metrics, we sought to increase understanding of factors driving high resource utilization (HRU) in emergent (EGS) versus same-day elective (SDGS) general surgery patients. METHODS: General surgery procedures from the 2016 ACS-NSQIP public use file were grouped according to the first four digits of the primary procedure CPT code. Groups having at least 100 of both elective and emergent cases were included (22 groups; 83,872 cases). HRU patients were defined as those in-hospital >7D, returned to the OR, readmitted, and/or had morbidity likely requiring an intensive care unit (ICU)stay. Independent NSQIP predictors of HRU were identified through forward regression; P for entry < 0.05, for exit > 0.10. RESULTS: Of all patients, 33% were HRU. The three highest HRU procedures (total colectomy, enterolysis, and ileostomy) comprised a higher proportion of EGS than SDGS cases (10.3 versus 2.6%, P < 0.001). The duration of operation was 40 Min lower in EGS after adjustment. Thirty-nine of the remaining 40 HRU predictors were higher in EGS including preoperative SIRS/Sepsis (50 versus 2%), ASA classification IV-V (31 versus 5%), albumin <3.5 g/dL (40 versus 12%), transfers (26 versus 2%, P's < 0.001), septuagenarians (35 versus 25%) and disseminated cancer (6.3 versus 4.8%, P's < 0.001); while sex did not differ. After adjustment, EGS patients remained more likely to be HRU (odds ratio 2.5, 95% CI 2.4 - 2.6, P < 0.001). CONCLUSIONS: EGS patients utilize significantly more resources than SDGS patients above what can be adjusted for in the clinically robust ACS-NSQIP dataset. Distinctive payment and value-based performance models are necessary for EGS.

Perceptions of Equity and Inclusion in Acute Care Surgery: From the #EAST4ALL Survey.

OBJECTIVES AND BACKGROUND: The aim of this study was to characterize equity and inclusion in acute care surgery (ACS) with a survey to examine the demographics of ACS surgeons, the exclusionary or biased behaviors they witnessed and experienced, and where those behaviors happen. A major initiative of the Equity, Quality, and Inclusion in Trauma Surgery Practice Ad Hoc Task Force of the Eastern Association for the Surgery of Trauma was to characterize equity and inclusion in ACS. To do so, a survey was created with the above objectives. METHODS: A cross-sectional, mixed-methods anonymous online survey was sent to all EAST members. Closed-ended questions are reported as percentages with a cutoff of α = 0.05 for significance. Quantitative results were analyzed focusing on mistreatment and bias. RESULTS: Most respondents identified as white, non-Hispanic and male. In the past 12 months, 57.5% of females witnessed or experienced sexual harassment, whereas 48.6% of surgeons of color witnessed or experienced racial/ethnic discrimination. Sexual harassment, racial/ethnic prejudice, or discrimination based on sexual orientation/sex identity was more frequent in the workplace than at academic conferences or in ACS. Females were more likely than males to report unfair treatment due to age, appearance or sex in the workplace and ACS (P ≤ 0.002). Surgeons of color were more likely than white, non-Hispanics to report unfair treatment in the workplace and ACS due to race/ethnicity (P < 0.001). CONCLUSIONS: This is the first survey of ACS surgeons on equity and inclusion. Perceptions of bias are prevalent. Minorities reported more inequity than their white male counterparts. Behavior in the workplace was worse than at academic conferences or ACS. Ensuring equity and inclusion may help ACS attract and retain the best and brightest without fear of unfair treatment.

Electrolyte Analysis and Replacement: Challenging a Paradigm in Surgical Patients.

Postoperative patients are susceptible to alterations in electrolyte homeostasis. Although electrolytes are replaced in critically ill patients, stable asymptomatic non-intensive care unit (ICU) patients often receive treatment of abnormal electrolytes. We hypothesize there is no proven benefit in asymptomatic patients. In 2016, using the electronic medical records and pharmacy database at a university academic medical center, we conducted a retrospective cost analysis of the frequency and cost of electrolyte analysis (basic metabolic panel [BMP], ionized calcium [Ca], magnesium [Mg], and phosphorus [P]) and replacement (potassium chloride [KCl], Mg, oral/iv Ca, oral/iv P) in perioperative patients. Patients without an oral diet order, with creatinine more than 1.4, age less than 16 years, admitted to the ICU, or with length of stay of more than 1 week were excluded. Nursing costs were calculated as a fraction of hourly wages per laboratory order or electrolyte replacement. One hundred thirteen patients met our criteria over 11 months. Mean length of stay was 4 days; mean age was 54 years; and creatinine was 0.67 ± 0.3. Electrolyte analysis laboratory orders (n = 1,045) totaled $6,978, and BMP was most frequently ordered accounting for 36% of laboratory costs. In total, 683 doses of electrolytes cost the pharmacy $1,780. Magnesium was most frequently replaced, followed by KCl, P, and Ca. Nursing cost associated with electrolyte analysis/replacement was $7,782. There is little evidence to support electrolyte analysis and replacement in stable asymptomatic noncritically ill patients, but their prevalence and cost ($146/case) in this study were substantial. Basic metabolic panels, pharmacy charges for potassium, and nursing staff costs accounted for the most significant portion of the total cost. Considering these data, further research should determine whether these practices are warranted.

Validation of the American Association for the Surgery of Trauma grading system for acute mesenteric ischemia-More than anatomic severity is needed to determine risk of mortality.

BACKGROUND: Acute mesenteric ischemia (AMI) is a highly morbid disease with a diverse etiology. The American Association for the Surgery of Trauma (AAST) proposed disease-specific grading scales intended to quantify severity based upon clinical, imaging, operative, and pathology findings. This grading scale has not been yet been validated for AMI. The goal of this study was to evaluate the correlation between the grading scale and complication severity. METHODS: Patients for this single center retrospective chart review were identified using diagnosis codes for AMI (ICD10-K55.0, ICD9-557.0). Inpatients >17 years old from the years 2008 to 2015 were included. The AAST grades (1-5) were assigned after review of clinical, imaging (computed tomography), operative and pathology findings. Two raters applied the scales independently after dialog with consensus on a learning set of cases. Mortality and Clavien-Dindo complication severity were recorded. RESULTS: A total of 221 patients were analyzed. Overall grade was only weakly correlated with Clavien-Dindo complication severity (rho = 0.27) and mortality (rho = 0.21). Computed tomography, pathology, and clinical grades did not correlate with mortality or outcome severity. There was poor interrater agreement between overall grade. A mortality prediction model of operative grade, use of vasopressors, preoperative serum creatinine and lactate levels showed excellent discrimination (c-index = 0.93). CONCLUSION: In contrast to early application of other AAST disease severity scales, the AMI grading scale as published is not well correlated with outcome severity. The AAST operative grade, in conjunction with vasopressor use, creatinine, and lactate were strong predictors of mortality. LEVEL OF EVIDENCE: Prognostic study, III.

Benchmarking the value of care: Variability in hospital costs for common operations and its association with procedure volume.

BACKGROUND: Efforts to improve health care value (quality/cost) have become a priority in the United States. Although many seek to increase quality by reducing variability in adverse outcomes, less is known about variability in costs. In conjunction with the American Association for the Surgery of Trauma Healthcare Economics Committee, the objective of this study was to examine the extent of variability in total hospital costs for two common procedures: laparoscopic appendectomy (LA) and laparoscopic cholecystectomy (LC). METHODS: Nationally weighted data for adults 18 years and older was obtained for patients undergoing each operation in the 2014 and 2016 National Inpatient Sample. Data were aggregated at the hospital-level to attain hospital-specific median index hospital costs in 2019 US dollars and corresponding annual procedure volumes. Cost variation was assessed using caterpillar plots and risk-standardized observed/expected cost ratios. Correlation analysis, variance decomposition, and regression analysis explored costs' association with volume. RESULTS: In 2016, 1,563 hospitals representing 86,170 LA and 2,276 hospitals representing 230,120 LC met the inclusion criteria. In 2014, the numbers were similar (1,602 and 2,259 hospitals). Compared with a mean of US $10,202, LA median costs ranged from US $2,850 to US $33,381. Laparoscopic cholecystectomy median costs ranged from US $4,406 to US $40,585 with a mean of US $12,567. Differences in cost strongly associated with procedure volume. Volume accounted for 9.9% (LA) and 12.4% (LC) of variation between hospitals, after controlling for the influence of other hospital (8.2% and 5.0%) and patient (6.3% and 3.7%) characteristics and in-hospital complications (0.8% and 0.4%). Counterfactual modeling suggests that were all hospitals to have performed at or below their expected median cost, one would see a national cost savings of greater than US $301.9 million per year (95% confidence interval, US $280.6-325.5 million). CONCLUSION: Marked variability of median hospital costs for common operations exists. Differences remained consistent across changing coding structures and database years and were strongly associated with volume. Taken together, the findings suggest room for improvement in emergency general surgery and a need to address large discrepancies in an often-overlooked aspect of value. LEVEL OF EVIDENCE: Epidemiological, level III.

Cost Burden and Mortality in Rural Emergency General Surgery Transfer Patients.

BACKGROUND: Recent articles have suggested regionalization of some emergency general surgery (EGS) problems to tertiary referral centers. We sought to characterize the clinical and cost burden of such transfers to our tertiary referral center. MATERIALS AND METHODS: Data were collected retrospectively for nine EGS diagnoses for patients admitted to the EGS service during calendar years 2015 and 2016. Patients were grouped as inpatient transfers (IPTs), Emergency Department transfers (EDTs), or local admissions (LAs). Demographic data, length of stay at originating site, insurance status, Charlson Comorbidity Index, and all relevant financial data were obtained. RESULTS: Six hundred sixty-three patients were reviewed: 93 IPTs, 343 EDTs, and 227 LAs. IPTs required longer lengths of stay (7.0 d compared to 4.0 d for EDTs and 3.0 d for LAs), higher median direct costs, and higher case mix index, which produced a higher median revenue but averaged a median net loss (-$264 compared to +$2436 for EDTs and +$3125 for LAs). The IPTs had higher median comorbidities (Charlson Comorbidity Index 3.5 versus 2.9 for EDTs and 2.0 for LAs), age (62 y versus 58 for EDTs and 52 for LAs), and mortality rate (7.5% versus 2.3% for EDTs and 0.4% for LAs). CONCLUSIONS: Patients who present to a tertiary care EGS service as an IPT from another hospital have more comorbidities, higher mortality rate, and result in a financial loss. These data suggest the need for adequate risk adjustment in quality assessment of tertiary referral center outcomes and the need for increased financial reimbursement for the care of these patients.

Appendicitis Grade, Operative Duration, and Hospital Cost.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) established a grading system for appendicitis to allow prediction of risk and outcomes, to assist in quality improvement and resource management, and to provide a framework for research. Grading is determined in clinical, imaging, operative, and pathologic categories, but has not been completely validated. Our aim was to validate appendicitis grade with respect to duration of symptoms, operative duration, and hospital costs. STUDY DESIGN: We performed a retrospective medical record review, working backward until at least 40 of each grade of appendicitis were reviewed. Patients 8 years old and younger and those treated nonoperatively were excluded. Appendicitis severity was determined using the AAST grading scale (I to V), with V being the most severe. Statistical comparisons were made between increased grade and duration of symptoms, operative duration, hospital costs, and revenue. Data were analyzed using ANOVA or chi-square tests as appropriate. RESULTS: A total of 1,099 appendectomies performed between August 2013 and December 2016 were analyzed. Most were low grade. Median age was 18 years old, and 44.4% were female. Patients with increasing AAST grade had a longer symptom duration (p < 0.001), longer operative duration (p < 0.001), increased direct costs (p < 0.001) in every category measured (operating room, pharmacy, imaging, lab), and contribution margin (p < 0.001). CONCLUSION: The AAST appendicitis grade is a valid predictor of disease severity as defined by operative duration, hospital cost, and revenue. Duration of symptoms predicts severity. Appendicitis grade can be used in clinical care, residency training, and resource allocation.

An acute care surgery service generates a positive contribution margin in an appropriately staffed hospital.

BACKGROUND: Acute care surgery (ACS) includes trauma, surgical critical care, and emergent general surgery. There is a national shortage of institutions that can provide for patients needing access to emergency surgical care. Inability to fund ACS surgeons can be a barrier. We hypothesize that an ACS service, in an appropriately staffed hospital, generates a positive contribution margin (CM). STUDY DESIGN: Fiscal data for 2009 were retrospectively reviewed at the University of Kentucky, a Level I trauma center with an ACS service. Contribution margin (ie, net revenue minus direct costs) and mean length of stay were calculated for all patients admitted to the ACS service. Inpatient data were stratified by trauma vs general surgery, emergent vs elective, and by payor mix. RESULTS: Annual CM associated with the 5 ACS faculty was $21,799,000. Trauma generated higher CM than general surgery. General surgery had a greater CM, more if emergent than if elective ($9,500 vs $5,500; p < 0.01). Self-payment was lower with emergent general surgery vs trauma (20% vs 25%; p = 0.02). CONCLUSIONS: Acute care surgery generates a positive CM. Emergent general surgery generates a greater CM than elective general surgery because of increased case mix index. These data suggest that hospital subsidization of acute care surgeons is financially feasible and might address the surgical workforce shortage and the critical problem of access to emergency surgical services.

As-needed antihypertensive therapy in surgical patients, why and how: challenging a paradigm.

Hypertension is common in hospitalized patients and there are many causes. Some patients have no prior history of hypertension, few symptoms, and no apparent morbidity related to acute rises in blood pressure. Though there is no established guideline for therapy in these cases, patients often receive therapy directed at the abnormal vital sign. It is hypothesized that this practice is common and the associated costs are significant. Using the inpatient pharmacy database at the University of Kentucky Chandler Medical Center, a verified Level I trauma center and quaternary referral center, patients on the emergency general surgery or orthopedic surgery services receiving intravenous hydralazine, metoprolol, or labetalol were identified. Subjects were analyzed for indications, parameters, associated history of hypertension, and direct costs. Over the 4-month study period, 114 subjects received 522 drug doses. More than half (55%) of subjects had a prior history of hypertension but only 75 per cent were started on their home medication. Of those without hypertension before admission, 18 per cent required therapy at discharge. Labetalol was the most frequently used agent and total pharmacy costs for this cohort of patients was over $1200. Pro re nata (PRN), short-acting antihypertensive therapy has little evidence base in asymptomatic patients, but its prevalence is high on surgical services. The cost is significant, especially when extrapolated to the larger hospital population at this single institution. Further research is warranted to determine the prevalence of this practice in other centers or national regions, as well as its cost and benefit.
