Health care disparities (differential access, care, and outcomes owing to factors such as race/ethnicity) are widely established. Compared with other groups, African American individuals have an increased mortality risk across multiple surgical procedures. Gender, sexual orientation, age, and geographic disparities are also well documented. Further research is needed to mitigate these inequities. To do so, the American College of Surgeons and the National Institutes of Health-National Institute of Minority Health and Disparities convened a research summit to develop a national surgical disparities research agenda and funding priorities. Sixty leading researchers and clinicians gathered in May 2015 for a 2-day summit. First, literature on surgical disparities was presented within 5 themes: (1) clinician, (2) patient, (3) systemic/access, (4) clinical quality, and (5) postoperative care and rehabilitation-related factors. These themes were identified via an exhaustive preconference literature review and guided the summit and its interactive consensus-building exercises. After individual thematic presentations, attendees contributed research priorities for each theme. Suggestions were collated, refined, and prioritized during the latter half of the summit. Breakout sessions yielded 3 to 5 top research priorities by theme. Overall priorities, regardless of theme, included improving patient-clinician communication, fostering engagement and community outreach by using technology, improving care at facilities with a higher proportion of minority patients, evaluating the longer-term effect of acute intervention and rehabilitation support, and improving patient centeredness by identifying expectations for recovery. The National Institutes of Health and American College of Surgeons Summit on Surgical Disparities Research succeeded in identifying a comprehensive research agenda. Future research and funding priorities should prioritize patients’ care perspectives, workforce diversification and training, and systematic evaluation of health technologies to reduce surgical disparities.

BACKGROUND: We have previously shown that overall cost of hospitalization for emergency general surgery (EGS) diseases is more than $28 billion annually and rising. The purposes of this study were to estimate the costs associated with specific EGS diseases and to identify factors associated with high-cost hospitalizations. METHODS: The American Association for the Surgery of Trauma definition was used to identify hospitalizations of adult EGS patients in the 2010 National Inpatient Sample data. Cost of each hospitalization was obtained using cost-to-charge ratio in National Inpatient Sample. Regression analysis was used to estimate the cost for each EGS disease adjusted for patient and hospital characteristics. Hospitalizations with cost exceeding 75th percentile for each EGS disease were compared with lower-cost hospitalizations to identify factors associated with high cost. RESULTS: Thirty-one EGS diseases resulted in 2,602,074 hospitalizations nationwide in 2010 at an average adjusted cost of $10,110 (95% confidence interval, $10,086-$10,134) per hospitalization. Of these, only nine diseases constituted 80% of the total volume and 74% of the total cost. Empyema chest, colorectal cancer, and small intestine cancer were the most expensive EGS diseases with adjusted mean cost per hospitalization exceeding $20,000, while breast infection, abdominal pain, and soft tissue infection were the least expensive, with mean adjusted costs of less than $7,000 per hospitalization. The most important factors associated with high-cost hospitalizations were the number and type of procedures performed (76.2% of variance), but a region in Western United States (11.3%), Medicare and Medicaid payors (2.6%), and hospital ownership by public or not-for-profit entities (5.6%) were also associated with high-cost hospitalizations. CONCLUSION: A small number of diseases constitute a vast majority of EGS hospitalizations and their cost. Attempts at reducing the cost of EGS hospitalization will require controlling the cost of procedures.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a new grading system for uniform description of anatomic severity of emergency general surgery (EGS) diseases, ranging from Grade I (mild) to Grade V (severe). The purpose of this study was to determine the relationship of AAST grades for acute colonic diverticulitis with patient outcomes. A secondary purpose was to propose an EGS quality improvement program using risk-adjusted center outcomes, similar to National Surgical Quality Improvement Program and Trauma Quality Improvement Program methodologies. METHODS: This was a retrospective study of 1,105 patients (one death) from 13 centers. At each center, two reviewers (blinded to each other’s assignments) assigned AAST grades. Interrater reliability was measured using kappa coefficient. Relationship between AAST grade and clinical events (complications, intensive care unit use, surgical intervention, and 30-day readmission) as well as length of stay was measured using regression analyses to control for age, comorbidities, and physiologic status at the time of admission. Final model was also used to calculate observed-to-expected (O-E) ratios for adverse outcomes (death, complications, readmissions) for each center. RESULTS: Median age was 54 years, 52% were males, 43% were minorities, and 22% required a surgical intervention. Almost two thirds had Grade I or II disease. There was a high level of agreement for grades between reviewers (kappa = 0.81). Adverse events increased from 13% for Grade I, to 18% for Grade II, 28% for Grade III, 44% for Grade IV, and 50% for Grade V. Regression analysis showed that higher disease grades were independently associated with all clinical events and length of stay, after adjusting for age, comorbidities, and physiology. O-E ratios showed statistically insignificant variations in risk of death, complications, or readmissions. CONCLUSION: AAST grades for acute colonic diverticulitis are independently associated with clinical outcomes and resource use. EGS quality improvement program methodology that incorporates AAST grade, age, comorbidities, and physiologic status may be used for measuring quality of EGS care. High-quality EGS registries are essential for developing meaningful quality metrics. LEVEL OF EVIDENCE: Prognostic study, level V.
