Comparison of outcomes after appendectomy in First Nations and non-First Nations patients in Northern Alberta.

BACKGROUND: Internationally, Indigenous Peoples experience worse surgical outcomes than non-Indigenous patients, but equity of surgical care is less well studied in Canada. This study compares outcomes after appendectomy in First Nations and non-First Nations patients. METHODS: In this population-based study, we reviewed administrative data of patients who underwent appendectomy between Apr. 1, 2004, and Mar. 31, 2017, in Northern Alberta. Demographic variables and characteristics of surgical care for First Nations and non-First Nations patients were collected. We identified adverse outcomes by the presence of predefined administrative codes. We identified variables related to a complex postoperative course (at least 1 of wound dehiscence, surgical site infection, abscess, bowel obstruction, pneumonia, deep vein thrombosis, sepsis, emergency department visit, readmission or death within 30 d after appendectomy) through a logistic regression model, and those related to longer length of stay using a Cox proportional hazards model. RESULTS: A total of 28 453 patients met the selection criteria, of whom 1737 (6.1%) had First Nations status. Compared to non-First Nations patients, First Nations patients were younger, lived farther away from the hospital of their appendectomy, were in lower socioeconomic quintiles, and had higher rates of obesity and diabetes (all p < 0.001). After adjustment for age, sex, distance to hospital, socioeconomic deprivation and comorbidities, First Nations status remained independently associated with higher rates of adverse outcomes (odds ratio 1.548, 95% confidence interval [CI] 1.384-1.733) and longer lengths of stay (hazard ratio 0.877, 95% CI 0.832-0.924). CONCLUSION: Although rurality, comorbidities and socioeconomic status contributed to worse outcomes after appendectomy for First Nations patients, First Nations status remained independently associated with worse surgical outcomes. Surgical care, an integral component of health care delivery, must be improved for First Nations patients in order to achieve equitable health care.

Intersectionality of Gender and Visible Minority Status Among General Surgery Residents in Canada.

Importance: Within medical specialties, surgical disciplines disproportionately and routinely demonstrate the greatest underrepresentation of women and individuals from racial/ethnic minority groups. Understanding the role that diversity plays in surgical resident training may identify strategies that foster resident resiliency, optimize surgical training, and improve patient outcomes. Objective: To examine the implication of gender and visible minority (VM [ie, nonaboriginal people who are not White individuals]) status for resiliency and training experiences of general surgery residents in Canada. Design, Setting, and Participants: In this survey study, a 129-item questionnaire was emailed from May 2018 to July 2018 to all residents enrolled in all Canadian general surgery training programs during the 2017-2018 training year. Survey responses were extracted and categorized into 5 major themes. The survey was designed by the Resident Committee and reviewed by the Governing Board of the Canadian Association of General Surgeons. French and English versions of the survey were created, distributed, and administered using Google Forms. Main Outcomes and Measures: Survey questions were formulated to characterize resident diversity and training experience. Self-perceptions of diversity, mentorship, and training experience were evaluated using a 5-point Likert scale (1 for strongly disagree, 2 for disagree, 3 for neither agree or disagree, 4 for agree, and 5 for strongly agree) and open-ended responses. The frequency of perceived unprofessional workplace encounters was evaluated using a 5-point scale (1 for daily, 2 for weekly, 3 for monthly, 4 for annually, and 5 for never). Results: Of the 510 general surgery residents invited, a total of 210 residents (40.5%) completed the survey. Most respondents were younger than 30 years (119 [56.7%]), were women (112 [53.3%]), reported English as their first language (133 [63.3%]), did not identify as a VM (147 [70.0%]), had no dependents (184 [87.6%]), and were Canadian medical graduates (178 [84.8%]). Women residents who identified as VM compared with male residents who did not identify as a VM were less likely to agree or strongly agree that they had a collegial relationship with staff, (21 [63.6%] vs 61 [89.7%]; P = .01), to feel like they fit in with their training programs (21 [63.6%] vs 56 [82.3%]; P = .003), and to feel valued at work (15 [45.4%] vs 47 [69.1%]; P = .03). Both female residents and female residents who identified as VM described significant concerns about receiving fewer training opportunities because of their gender vs their male peers (54 [48.2%] vs 3 [3.0%]; P < .001). Ninety-one of 112 female residents (81.2%) reported feeling that their medical expertise was dismissed because of their gender at least once annually, with 37 women (33.0%) experiencing dismissal of their expertise at least once every week (P < .001). In contrast, 98% of male residents reported never experiencing dismissal of their medical expertise because of their gender. Similarly, residents with VM status vs those without VM status reported at least monthly dismissal of their expertise because of their race/ethnicity (9 of 63 [14.3%] vs 1 of 147 [0.7%]; P < .001). Conclusions and Relevance: In this study, female sex and VM status appeared to be associated with adverse implications for the training experience of general surgery residents. These findings suggest that new strategies focused on the intersectionality of gender and race/ethnicity are needed to improve the training experience of at-risk residents.

Effect of major abdominal surgery on the host immune response to infection.

PURPOSE OF REVIEW: The present review summarizes key studies on the effects of major abdominal surgery on the host response to infection published during the last 18 months. RECENT FINDINGS: Surgical trauma causes stereotyped systemic proinflammatory and compensatory anti-inflammatory reactions. It is leukocyte reprogramming rather than general immune suppression. The list of recent findings is long. Preoperative infectious challenge was found to increase survival. Obesity is associated with increased production of interleukin-17A in peritonitis. Abdominal surgery alters expression of toll-like receptors (TLRs). The acute phase reaction down-regulates the transcription factor carbohydrate response element binding protein. Myosin light chain kinase activation is a final pathway of acute tight junction regulation of gut barrier and zonula occludens 1 protein is an essential effector. The brain is involved in regulating the immune and gut system. Elimination of lipopolysaccharide is challenging. Th1/Th2 ratio is lowered in patients with postoperative complications. Cholinergic anti-inflammatory pathways can inhibit tissue damage. The new substance PXL01 prevents adhesions. Postoperative infection causes incisional hernias. Hypothermia reduced human leukocyte antigen DR surface expression and delayed tumor necrosis factor clearance. Systems biology identified interferon regulatory factor 3 as the negative regulator of TLR signaling. Protective immunity could contribute defeating surgical infections. SUMMARY: Systemic inflammation is the usual response to trauma. All organs seem to be involved and linked up in cybernetic systems aiming at reconstitution of homeostasis. Although knowledge is still fragmentary, it is already difficult to integrate known facts and new technologies are required for information processing. Defining criteria to develop therapeutic strategies requires much more insight into molecular mechanisms and cybernetics of organ systems.
