Underrepresented Minorities are Underrepresented Among General Surgery Applicants Selected to Interview

OBJECTIVE

Diversity is an ill-defined entity in general surgery training. The Accreditation Council for Graduate Medical Education recently proposed new common program requirements including verbiage requiring diversity in residency. "Recruiting" for diversity can be challenging within the constraints of geographic preference, type of program, and applicant qualifications. In addition, the Match process adds further uncertainty. We sought to study the self-identified racial/ethnic distribution of general surgery applicants to better ascertain the characteristics of underrepresented minorities (URM) within the general surgery applicant pool.

DESIGN

Program-specific data from the Electronic Residency Application Service was collated for the 2018 medical student application cycle. Data were abstracted for all participating programs' applicants and those selected to interview. Applicants who did not enter a self-identified race/ethnicity were excluded from analysis. URM were defined as those identifying as Black/African American, Hispanic/Latino/of Spanish origin, American Indian/Alaskan Native, or Native Hawaiian/Pacific Islander-Samoan. Appropriate statistical analyses were accomplished.

SETTING

Ten general surgery residency programs-5 independent programs and 5 university programs.

PARTICIPANTS

Residency applicants to the participating general surgery residency programs.

RESULTS

Ten surgery residency programs received 10,312 applications from 3192 unique applicants. Seven hundred and seventy-eight applications did not include a self-identified race/ethnicity and were excluded from analysis. The racial/ethnic makeup of applicants in this study cohort was similar to that from 2017 to 2018 Electronic Residency Application Service data of 4262 total applicants to categorical general surgery. Programs received a median of 1085 (range: 485-1264) applications each and altogether selected 617 unique applicants for interviews. Overall, 2148 applicants graduated from US medical schools, and of those, 595 (28%) were offered interviews. The mean age of applicants was 28.8 ± 3.8 years and 1316 (41%) were female. Hispanic/Latino/of Spanish origin, Black, and American Indian/Alaskan Native/Hawaiian/Pacific Islander-Samoan applicants constituted 12%, 8%, and 1% of total applicants, but only 8%, 6%, and 1% of those selected for interview. Overall, 29% of applicants had United States Medical Licensing Examination (USMLE) Step 1 scores ≤220; 37 (6%) of those selected for interviews had a USMLE Step 1 score of ≤220. A higher proportion of URM applicants had USMLE scores ≤220 compared to White and Asian applicants. Non-white self-identification was a significant independent predictor of a lower likelihood of interview selection. Female gender, USMLE Step 1 score >220, and graduating from a US medical school were associated with an increased likelihood of being selected to interview.

CONCLUSIONS

URM applicants represented a disproportionately smaller percentage of applicants selected for interview. USMLE Step 1 scores were lower among the URM applicants. Training programs that use discreet USMLE cutoffs are likely excluding URM at a higher rate than their non-URM applicants. Attempts to recruit racially/ethnically diverse trainees should include program-level analysis to determine disparities and a focused strategy to interview applicants who might be overlooked by conventional screening tools.

Diversity, Equity and Inclusion in Medicine: Why It Matters and How do We Achieve It?

Diversifying the medical work force is critical to reducing health care disparity and improving patient outcomes. This manuscript offers a comprehensive review of best practices to improve both the recruitment and the retention of underrepresented minorities in training programs and beyond.

Endoscopy and upper gastrointestinal contrast studies are complementary in evaluation of weight regain after bariatric surgery

BACKGROUND

To assess the utility of upper endoscopy (EGD) and upper gastrointestinal (UGI) contrast studies in the evaluation of weight regain after previous bariatric surgery.

METHODS

We retrospectively reviewed the findings of EGD and UGI studies for patients referred to our center for weight regain after bariatric surgery. All patients received a dietary assessment concomitant with the anatomic evaluations.

RESULTS

From January 2003 and March 2006, 30 patients qualified for the study (25 women and 5 men, average age 49 years). Of the 30 patients, 16 had undergone gastroplasty and 14 open Roux-en-Y gastric bypass. Of the 30 patients, 27 (90%) had > or =1 abnormality detected on UGI study or EGD. Of these abnormalities, 10 were gastrogastric fistulas, 8 of which were detected with both UGI study and EGD; 11 dilated pouches were diagnosed by EGD but only 2 were also diagnosed on the UGI study. An enlarged stoma size was diagnosed in 7 patients (6 by EGD and 1 on the UGI study). Also, the UGI study diagnosed 1 Roux limb and 7 esophageal abnormalities not seen on EGD, and EGD diagnosed 4 esophageal and 3 gastric abnormalities not seen on the UGI study. On the basis of these findings and the dietary evaluation, 23 patients (77%) were offered a revisional procedure.

CONCLUSION

EGD and UGI contrast studies are complementary in the evaluation of patients with weight regain after bariatric surgery. The combination of the 2 studies detected all the gastrogastric fistulas present. EGD provided more useful pouch and stomal information, and the UGI study detected esophageal or Roux limb abnormalities that frequently require additional evaluation.

Underrepresented Minorities in General Surgery Residency: Analysis of Interviewed Applicants, Residents, and Core Teaching Faculty

BACKGROUND

The Accreditation Council for Graduate Medical Education (ACGME) requires diversity in residency. The self-identified race/ethnicities of general surgery applicants, residents, and core teaching faculty were assessed to evaluate underrepresented minority (URM) representation in surgery residency programs and to determine the impact of URM faculty and residents on URM applicants' selection for interview or match.

STUDY DESIGN

Data from the 2018 application cycle were collated for 10 general surgery programs. Applicants without a self-identified race/ethnicity were excluded. URMs were defined as those identifying as black/African American, Hispanic/Latino/of Spanish origin, and American Indian/Alaskan Native/Native Hawaiian/Pacific Islander-Samoan. Statistical analyses included chi-square tests and a multivariate model.

RESULTS

Ten surgery residency programs received 9,143 applications from 3,067 unique applicants. Applications from white, Asian, Hispanic/Latino, black/African American, and American Indian applicants constituted 66%, 19%, 8%, 7% and 1%, respectively, of those applications selected to interview and 66%, 13%, 11%, 8%, and 2%, respectively, of applications resulting in a match. Among programs' 272 core faculty and 318 current residents, 10% and 21%, respectively, were identified as URMs. As faculty diversity increased, there was no difference in selection to interview for URM (odds ratio [OR] 0.83; 95% CI 0.54 to 1.28, per 10% increase in faculty diversity) or non-URM applicants (OR 0.68; 95% CI 0.57 to 0.81). Similarly, greater URM representation among current residents did not affect the likelihood of being selected for an interview for URM (OR 1.20; 95%CI 0.90 to 1.61) vs non-URM applicants (OR 1.28; 95% CI 1.13 to 1.45). Current resident and faculty URM representation was correlated (r = 0.8; p = 0.005).

CONCLUSIONS

Programs with a greater proportion of URM core faculty or residents did not select a greater proportion of URM applicants for interview. However, core faculty and resident racial diversity were correlated. Recruitment of racially/ethnically diverse trainees and faculty will require ongoing analysis to develop effective recruitment strategies.

Deficient expression of DNA repair enzymes in early progression to sporadic colon cancer

Background

Cancers often arise within an area of cells (e.g. an epithelial patch) that is predisposed to the development of cancer, i.e. a "field of cancerization" or "field defect." Sporadic colon cancer is characterized by an elevated mutation rate and genomic instability. If a field defect were deficient in DNA repair, DNA damages would tend to escape repair and give rise to carcinogenic mutations.

Purpose

To determine whether reduced expression of DNA repair proteins Pms2, Ercc1 and Xpf (pairing partner of Ercc1) are early steps in progression to colon cancer.

Results

Tissue biopsies were taken during colonoscopies of 77 patients at 4 different risk levels for colon cancer, including 19 patients who had never had colonic neoplasia (who served as controls). In addition, 158 tissue samples were taken from tissues near or within colon cancers removed by resection and 16 tissue samples were taken near tubulovillous adenomas (TVAs) removed by resection. 568 triplicate tissue sections (a total of 1,704 tissue sections) from these tissue samples were evaluated by immunohistochemistry for 4 DNA repair proteins. Substantially reduced protein expression of Pms2, Ercc1 and Xpf occurred in field defects of up to 10 cm longitudinally distant from colon cancers or TVAs and within colon cancers. Expression of another DNA repair protein, Ku86, was infrequently reduced in these areas. When Pms2, Ercc1 or Xpf were reduced in protein expression, then either one or both of the other two proteins most often had reduced protein expression as well. The mean inner colon circumferences, from 32 resections, of the ascending, transverse and descending/sigmoid areas were measured as 6.6 cm, 5.8 cm and 6.3 cm, respectively. When combined with other measurements in the literature, this indicates the approximate mean number of colonic crypts in humans is 10 million.

Conclusions

The substantial deficiencies in protein expression of DNA repair proteins Pms2, Ercc1 and Xpf in about 1 million crypts near cancers and TVAs suggests that the tumors arose in field defects that were deficient in DNA repair and that deficiencies in Pms2, Ercc1 and Xpf are early steps, often occurring together, in progression to colon cancer.

Epigenetic field defects in progression to cancer

A field defect is a field of pre-malignant tissue in which a new cancer is likely to arise. Field defects often appear to be histologically normal under the microscope. Recent research indicates that cells within a field defect characteristically have an increased frequency of epigenetic alterations and these may be fundamentally important as underlying factors in progression to cancer. However, understanding of epigenetic field defects is at an early stage, and the work of Katsurano et al published this year, is a key contribution to this field. One question examined by Katsurano et al was how early could the formation of an epigenetic field defect be detected in a mouse colitis model of tumorigenesis. They highlighted a number of measurable epigenetic alterations, detected very early in normal appearing tissue undergoing histologically invisible tumorigenesis. They also documented the increasing presence of the epigenetic alterations at successive times during progression to cancer. In this commentary, we offer a perspective on the changes they observed within a broader sequence of epigenetic events that occur in progression to cancer. In particular, we highlight the likely central role of epigenetic deficiencies in DNA repair gene expression that arise during progression to cancer.

Modulation of ROS levels in fibroblasts by altering mitochondria regulates the process of wound healing

Mitochondria are the major source of reactive oxygen species (ROS) in fibroblasts which are thought to be crucial regulators of wound healing with a potential to affect the expression of nuclear genes involved in this process. ROS generated by mitochondria are involved in all stages of tissue repair process but the regulation of ROS-generating system in fibroblasts still remains poorly understood. The purpose of this study was to better understand molecular mechanisms of how the regulation of ROS levels generated by mitochondria may influence the process of wound repair. Cybrid model system of mtDNA variations was used to study the functional consequences of altered ROS levels on wound healing responses in a uniform nuclear background of cultured ρ(0) fibroblasts. Mitochondrial ROS in cybrids were modulated by antioxidants that quench ROS to examine their ability to close the wound. Real-time PCR arrays were used to investigate whether ROS generated by specific mtDNA variants have the ability to alter expression of some key nuclear-encoded genes central to the wound healing response and oxidative stress. Our data suggest levels of mitochondrial ROS affect expression of some nuclear encoded genes central to wound healing response and oxidative stress and modulation of mitochondrial ROS by antioxidants positively affects in vitro process of wound closure. Thus, regulation of mitochondrial ROS-generating system in fibroblasts can be used as effective natural redox-based strategy to help treat non-healing wounds.

Disparities in incidence of early- and late-onset colorectal cancer between Hispanics and Whites: A 10-year SEER database study

BACKGROUND

Racial disparities in incidence of colorectal cancer (CRC) exist. In Hispanics, CRC was the second most commonly diagnosed cancer in 2012.

METHODS

We abstracted the national estimates for Hispanics/Whites with CRC using the SEER database between 2000 and 2010. Trends in incidence, mortality, gender and stage of disease were analyzed for early-onset (age<50; EO - young) and late-onset (age>50; LO - old) cases.

RESULTS

The overall incidence of CRC increased by 48% in Hispanics. 38% increase in incidence of LO CRC and 80% increase in incidence of EO CRC was seen in this ethnic group. Hispanics and Whites showed higher percentage of distant tumors for both age groups. There was no deviation in overall trend between males and females.

CONCLUSIONS

Although there is an overall decrease in incidence of CRC in Whites increase was seen in Hispanics. While incidence of EO CRC is increasing in both races, LO CRC incidence is increasing in Hispanics not in Whites. This data suggest that disparities in incidence of EO and LO CRC exist between Hispanics and Whites.

Diversity in the Last Decade of the Association of Program Directors in Surgery: A Descriptive Analysis of Leadership and Future Directions

OBJECTIVE

The Association of Program Directors in Surgery Diversity and Inclusion Taskforce (APDS-DIT) was created in 2017 after the Executive Committee recognized low diversity in its membership. The DIT was charged to address gaps in diversity and inclusion at various phases of training and development from medical student to surgical leader. The aim of this study was to examine APDS demographics and determine the status of inclusion of women, racial and ethnic minorities, and nonuniversity surgeons.

DESIGN

Eleven years (2008-2018) of APDS annual-meeting programs, web directory, 2018-membership lists, and 2017-AAMC data were analyzed. Leadership positions were examined by officer (program chair/vice chair, executive committee, and board of directors. Internet searches identified gender, race, and institutional affiliation. Representative members to other organizations, resident liaisons, and historian members were excluded. APDS "Member," "Associate," and "Resident" lists and AAMC data were divided by gender.

RESULTS

Fifty-one individuals fulfilled 223 leadership positions over 11 years; 13 (25%) were women and 5 (10%) were non-Caucasian. Since 2013, the percentage of nonuniversity surgeons in APDS leadership has declined while, over the last 2 years, the percentage of women and ethnic/racial minority has increased. In 2018, the percentage of women in leadership (38%) was higher than the percentage of women in membership (combined total of program directors and associate program directors [26%]) and nonuniversity-affiliated surgeons comprised 35% of the APDS membership but only 14% of leadership roles.

CONCLUSIONS

Over the last 11 years, representation of women, non-Caucasians, and nonuniversity surgeons has been at or less than 1/3 of their counterparts. As an organization that is tasked with creating future generations of the surgical workforce, it is imperative to recognize an under-representation of those members with diverse backgrounds that would add to the creative growth of the organization. The creation of the APDS-DIT emphasizes the organization's commitment to diversity and inclusion and an effort to create a pipeline of diverse leaders in the APDS and surgical training in general.

Delphi Consensus on Intraoperative Technical/Surgical Aspects to Prevent Surgical Site Infection after Colorectal Surgery

BACKGROUND

Previous studies have focused on the development and evaluation of care bundles to reduce the risk of surgical site infection (SSI) throughout the perioperative period. A focused examination of the technical/surgical aspects of SSI reduction during CRS has not been conducted. This study aimed to develop an expert consensus on intraoperative technical/surgical aspects of SSI prevention by the surgical team during colorectal surgery (CRS).

STUDY DESIGN

In a modified Delphi process, a panel of 15 colorectal surgeons developed a consensus on intraoperative technical/surgical aspects of SSI prevention undertaken by surgical personnel during CRS using information from a targeted literature review and expert opinion. Consensus was developed with up to three rounds per topic, with a prespecified threshold of ≥70% agreement.

RESULTS

In 3 Delphi rounds, the 15 panelists achieved consensus on 16 evidence-based statements. The consensus panel supported the use of wound protectors/retractors, sterile incision closure tray, preclosure glove change, and antimicrobial sutures in reducing SSI along with wound irrigation with aqueous iodine and closed-incision negative pressure wound therapy in high-risk, contaminated wounds.

CONCLUSIONS

Using a modified Delphi method, consensus has been achieved on a tailored set of recommendations on technical/surgical aspects that should be considered by surgical personnel during CRS to reduce the risk of SSI, particularly in areas where the evidence base is controversial or lacking. This document forms the basis for ongoing evidence for the topics discussed in this article or new topics based on newly emerging technologies in CRS.

Sporadic early-onset colon cancer expresses unique molecular features

BACKGROUND

The overall incidence of colon cancer (CC) has steadily declined in the last decades but has increased in patients under age 50 y. The etiology of early-onset (EO) CC is not understood. The aim of this study was to elucidate gene expression patterns in EOCC and show its uniqueness compared to late-onset (LO) disease.

METHODS

Two cohorts of patients with sporadic CC were identified. Tumors and matching noninvolved tissues from six EOCC patients (<50) and six late-onset colon cancers (LOCC) patients (>65) were obtained from pathology archives. De-paraffinized tissues were macrodissected from FFPE sections, RNA isolated, and used for expression profiling of 770 cancer-related genes representing 13 canonical pathways.

RESULTS

Among 770 genes assayed, changes in expression levels of 93 genes were statistically significant between EOCC and matching noninvolved tissues. There were also significant differences in expression levels of 118 genes between LOCC and matching noninvolved tissues. Detailed comparative gene expression analysis between EOCC and LOCC normalized to their matching noninvolved tissues revealed that changes in expression of 88 genes were unique to EOCC using the cutoff criteria of expression levels difference >2 fold and P value <0.01. From these differentially expressed genes specific to EOCC, 28 genes were upregulated and 60 genes downregulated. At the pathway level, RAS, MAPK, WNT, and DNARepair pathways were similarly deregulated in both age groups, whereas PI3K-AKT signaling was more specific to EOCC and cell cycle pathway to LOCC.

CONCLUSIONS

These results suggest that sporadic EOCC is characterized by distinct molecular events compared to LOCC.

Racial and gender disparities in the incidence of anal cancer: analysis of the Nationwide Inpatient Sample (NIS)

Background

Racial and gender disparities have been shown in other gastrointestinal cancers. However, there is a paucity of data on racial and gender disparities in anal cancer (AC). The aim of this study was to assess racial and gender disparities among patients with AC.

Methods

We analyzed data from the National Inpatient Sample (NIS) 2011 database of patients diagnosed with AC with age ≥18. Demographic data including age, race and gender were assessed. Patients were stratified based on race and gender. Log binomial regression was used to generate risk ratios.

Results

A total of 6,013,105 patients were assessed and 1,956 (0.03%) patients had AC. Female patients were more at risk of developing AC [relative risk (RR): 1.14, P=0.02]. Whites and Blacks had the highest incidence followed by Asians/Pacific Islanders. Black males had increased risk of AC (RR: 1.43, P<0.01). Amongst Hispanics; both males (RR: 0.69, P=0.05) and females (RR: 0.46, P<0.0001) had decreased risk of developing AC. Finally, we saw that Asian females had a much lower risk of developing AC (RR: 0.33, P<0.01).

Conclusions

Racial disparities and gender differences exist in the incidence of AC. Potential causes for this disparity are disparate access to healthcare, lack of education, and lack of awareness. Greater understanding of the racial disparity in AC can help identify at risk population and eventually lead to improved preventative measures to ultimately reduce the incidence of AC.

Postoperative pneumoperitoneum after colorectal surgery: Expectant vs surgical management

Postoperative pneumoperitoneum poses a clinical dilemma. Depending on the cause, its management includes a spectrum from simple observation and supportive care to surgical exploration. The aim of this paper is to present four clinical cases and propose an algorithm for the management of postoperative pneumoperitoneum based on available literature. The causes, diagnosis and possible complications arising from pneumoperitoneum will also be discussed. Three of the four cases presented were successfully managed conservatively and one had an exploratory laparotomy with negative findings. In such scenarios, it is important to consider the nonsurgical causes of pneumoperitoneum, which include pseudopneumoperitoneum, thoracic, abdominal, gynecological and idiopathic. These causes do not always require emergent exploratory laparotomy. The surgical team needs to consider the history, physical exam and diagnostic workup of the patient. If a patient presents with peritoneal signs, then exploratory laparotomy is a must. Since 10% of the cases of pneumoperitoneum are caused by nonsurgical entities, managed expectantly, a negative exploratory laparotomy and its associated risks are avoided.

Tryptophan autofluorescence imaging of neoplasms of the human colon

Detection of flat neoplasia is a major challenge in colorectal cancer screening, as missed lesions can lead to the development of an unexpected 'incident' cancer prior to the subsequent endoscopy. The use of a tryptophan-related autofluorescence has been reported to be increased in murine intestinal dysplasia. The emission spectra of cells isolated from human adenocarcinoma and normal mucosa of the colon were studied and showed markedly greater emission intensity from cancerous cells compared to cells obtained from the surrounding normal mucosa. A proto-type multispectral imaging system optimized for ultraviolet macroscopic imaging of tissue was used to obtain autofluorescence images of surgical specimens of colonic neoplasms and normal mucosa after resection. Fluorescence images did not display the expected greater emission from the tumor as compared to the normal mucosa, most probably due to increased optical absorption and scattering in the tumors. Increased fluorescence intensity in neoplasms was observed however, once fluorescence images were corrected using reflectance images. Tryptophan fluorescence alone may be useful in differentiating normal and cancerous cells, while in tissues its autofluorescence image divided by green reflectance may be useful in displaying neoplasms.

Adherence to a standardized infection reduction bundle decreases surgical site infections after colon surgery: a retrospective cohort study on 526 patients

BACKGROUND

Colon surgical site infections (SSI) are detrimental to patient safety and wellbeing. To achieve clinical excellence, our hospital set to improve patient safety for those undergoing colon surgery. Our goal was to implement a perioperative SSI prevention bundle for all colon surgeries to reduce colon surgery SSI rates.

METHODS

This retrospective cohort study evaluated the impact of implementing a perioperative SSI prevention bundle in patients undergoing colon surgery at Banner University Medical Center - Tucson. We compared SSI rates between the Pre- (1/1/2016 to 12/31/2016) and post-bundle (1/1/2017 to 12/31/2017) cohorts using a chi-square test.

RESULTS

In total, we included 526 consecutive patients undergoing colon surgery in our study cohort; 277 pre-bundle and 249 post-bundle implementation. The unadjusted SSI rates were 8.7 % and 1.2 %, pre- and post-bundle, respectively. Our CMS reportable standard infection rate decreased by 85.4 % from 3.08 to 0.45 after implementing our SSI prevention bundle.

CONCLUSIONS

Implementing a standardized colon SSI prevention bundle reduces the overall 30-day colon SSI rates and national standardized infection rates. We recommend implementing colon SSI reduction bundles to optimize patient safety and minimize colon surgical site infections.

Fungal inflammatory masses masquerading as colorectal cancer: a case report

Background

Non malignant invasive tumors of the colon and rectum are very rare. Gastrointestinal Basidiobolomycosis can present as a mass lesion mimicking colorectal cancer.

Case presentation

A 56 year old Caucasian male was evaluated for abdominal and pelvic pain for 4 weeks complicated by acute urinary retention. Radiological evaluation showed him to have recto-sigmoid and cecal mass. Endoscopic examination and biopsies did not reveal a definite diagnosis. Computerized tomography guided biopsy of the mass showed fungal elements consistent with gastrointestinal basidiobolomycosis. He was treated with Itraconazole for 12 months with very good clinical and radiological response.

Conclusion

Basidiobolomycosis of the gastrointestinal tract should be considered during evaluation of colorectal masses with atypical presentation. It is a rare entity seen more in endemic regions of the world for basidiobolomycosis including southwestern United States.

Contributing factors and short-term surgical outcomes of patients with early-onset rectal cancer

INTRODUCTION

The aim of this study was to evaluate patient factors that contribute to increased incidence of early onset rectal cancer and analyze the short-term surgical outcomes of patients undergoing surgery.

METHODS

A 2-year review (2015-2016) of the ACS-NSQIP included patients with rectal cancer who underwent surgical management. Patients were stratified into early-onset RC (<50-years) and late-onset RC (≥50-years).

RESULTS

We included a total of 7538 patients in the analysis. Overall, 14% of the patients had early-onset RC. Patients with early-onset RC were more likely to be Black and Hispanic. Additionally, they were more likely to present with higher TNM stages. Patients with early-onset RC had lower 30-day complications and lower 30-day mortality. There was no difference between the two groups regarding hospital length of stay or 30-day readmission. On regression analysis, there was no difference between the two groups regarding patient outcomes.

CONCLUSIONS

Racial disparities do exist in the incidence of RC. Young patients tend to have more aggressive disease, however, surgical outcomes between the two groups are comparable.

Racial disparities in the incidence of colon cancer in patients with inflammatory bowel disease

Background

Studies have explored the relationship between inflammatory bowel disease (IBD) [ulcerative colitis (UC) and Crohn's disease (CD)] and colon cancer (CC). Additionally, racial disparities in the incidence of CC is well known. However, the impact of racial disparity in IBD patients who develop CC remains unclear. The aim of this study is to address the knowledge gap in this particular group of patients.

Methods

A retrospective analysis was done using the National Inpatient Sample (NIS) database from 2011. We included patients with IBD over age ≥18 years with a diagnosis of CC. Patients were stratified by race, gender, age, presence of IBD and CC. Statistical analysis was performed to compare the groups.

Results

A total of 57,542 patients were included (CD: 36,357, UC: 21,001). Of all patients with and without IBD, advanced age, Black and Asian race conferred an increased risk of developing CC, whereas female gender, Hispanic and Native American race conferred a protective effect. In patients with IBD, advanced age conferred an increased risk for developing CC while female gender conferred a protective effect. In this subset of patients, black race conferred a protective effect.

Conclusions

Racial disparity exists in the overall incidence of CC and among patients with IBD who develop CC. Interestingly, black race conferred a protective effect for patients with IBD, contrary to what is seen in the general population. These findings could be attributed to the environmental factors and genetic makeup between racial groups. Further studies are warranted to better understand these disparities.

Disparities in Mangement of Patients with Benign Colorectal Disease: Impact of Urbanization and Specialized Care

Disparities in the management of patients with various medical conditions are well established. Colorectal diseases continue to remain one of the most common causes for surgical intervention. The aim of this study was to assess disparities (rural versus urban) in the surgical management of patients with noncancerous benign colorectal diseases. We hypothesized that there is no difference among rural versus urban centers (UC) in the surgical management for noncancerous benign colorectal diseases. The national estimates of surgical procedures for benign colorectal diseases from the National Inpatient Sample database 2011 representing 20 per cent of all in-patient admissions were abstracted. Patients undergoing procedures (abscess drainage, hemmoroidectomy, fistulectomy, and bowel resections) were included. Patients with colon cancer and those who underwent emergency surgery were excluded. The population was divided into two groups: urban and rural, based on the location of treatment. Outcome measures were in-hospital complications, mortality, and hospital costs. Subanalysis of UC was preformed: centers with colorectal surgeons and centers without colorectal surgeons. Regression analysis was performed. A total of 20,617 patients who underwent surgical intervention for benign colorectal diseases across 496 (urban: 342, rural: 154) centers, were included. Of the UC, 38.3 per cent centers had colorectal surgeons. Patients managed in UC had lower complication rate (7.6% vs 10.2%, P < 0.001), shorter hospital length of stay (4.7 ± 3.1 vs 5.9 ± 3.6 days, P < 0.001), and higher hospital costs ($56,820 ± $27,691 vs $49,341 ± $2,598, P < 0.001) compared with rural centers. On subanalysis, patients managed in UC with colorectal surgeons had 11 per cent lower incidence of in-hospital complications [odds ratio: 0.89 (95% confidence interval: 0.76–0.94)] and a shorter hospital length of stay [Beta: -0.72 (95% confidence interval: —0.81 to —0.65)] when compared with patients managed in UC without colorectal specialization. Disparities exit in outcomes of the patients with noncancerous benign colorectal diseases managed surgically in urban versus rural centers. Specialized care with colorectal surgeons at UC helps reduce adverse patient outcomes. Steps to provide effective and safe surgical care in a cost-effective manner across rural as well as UC are warranted. Level of evidence: Level III, retrospective cohort analysis.

Disparities in colon and rectal cancer queried individually between Hispanics and Whites

Background

Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer related deaths in the United States. Racial disparities between Hispanics and Whites exist for incidence of late-onset (LO) CRC. However, not much is known about potential disparities between colon cancer (CC) and rectal cancer (RC) incidence queried individually.

Methods

Using the SEER database data from 2000 to 2010, we obtained the national estimates of CC and RC for Hispanics and Whites. We analyzed trends in incidence, mortality, gender and stage of disease for early-onset (EO) (<50 years old) and LO (>50 years old) CC and RC.

Results

In Hispanics, the overall incidence of CC and RC increased by 47% and 52%, respectively; while in Whites, the overall incidence of CC and RC decreased by 13% and 2% respectively. Incidence of EO CC increased in both Hispanics and Whites by 83% and 17%, respectively, and incidence of EO RC also increased for both groups with a 76% increase in Hispanics and a 34% increase in Whites. For LO CC, the incidence increased by 37% in Hispanics while it decreased by 17% in Whites and for LO RC, the trend in incidence increased in Hispanics by 41%, but decreased in Whites by 11%.

Conclusions

This study established that the incidence of CC and RC are different and there is racial disparity in incidence between Whites and Hispanics. This study, hopefully, will help in crafting public policy that might help in addressing this disparity.

A Protocol-Driven Reduction in Surgical Site Infections After Colon Surgery

BACKGROUND

Surgical site infection (SSI) is an established quality indicator and predictor for adverse patient outcomes. Multiple strategies have been established to reduce SSI; however, optimum protocol remains unclear. The aim of the study was to assess the impact of established protocol on SSI after colon surgery.

METHODS

We established a colon SSI bundle in 2017, which includes a chlorhexidine prescrub followed by chloraPrep, betadine wound wash, antibiotic infused irrigation, use of closure tray, and incision coverage with silver impregnated dressing. Retrospective analysis of a 2-y (2016-2017) prospectively collected before and after analysis of all patients undergoing elective colon surgery was performed. Patients were divided into two groups: preprotocol (PP: year 2016) and postprotocol (PoP: year 2017). Patients in the two groups were matched using propensity score matching for age, gender, comorbidities, Anesthesiology Severity Score, indication of procedure, and procedure type. Outcome measures were SSI, hospital length of stay, and readmission rate.

RESULTS

A total of 328 patients were analyzed, and after propensity matching, 94 patients (PP:47 and PoP:47) were included. The mean age was 63.7 ± 16.4 y, 43.6% male, and 44.6% of procedures were performed laparoscopically. There was no difference in demographics, comorbidities, and procedure details between two groups. PoP patients had significantly lower superficial (odds ratio: 0.91 [0.74-0.98]; P = 0.045) and deep SSI (odds ratio:0.97 [0.65-0.99]; P = 0.048) than PP patients. PoP patient had shorter length of stay (P = 0.049) and trend toward lower readmission rate (P = 0.098) compared with PP patients and an 85% reduction in the Centers for Medicare and Medicaid Services standardized infection rate.

CONCLUSIONS

Protocol-driven patient care improves patient outcomes. SSI bundle reduced SSI in patient undergoing colon surgery. Establishing national SSI bundles will help standardize care and help optimize patient outcomes.

Effective Mentoring Across Differences-Best Practices and Effective Models to Address the Needs of Underrepresented Trainees in Surgical Residency Programs
