RESUMEN

BACKGROUND: With the primary objective of addressing the disparity in global surgical care access, the College of Surgeons of East, Central, and Southern Africa (COSECSA) trains surgeons. While sufficient operative experience is crucial for surgical training, the extent of utilization of minimally invasive techniques during COSECSA training remains understudied. METHODS: We conducted an extensive review of COSECSA general surgery trainees' operative case logs from January 1, 2015, to December 31, 2020, focusing on the utilization of minimally invasive surgical procedures. Our primary objective was to determine the prevalence of laparoscopic procedures and compare this to open procedures. We analyzed the distribution of laparoscopic cases across common indications such as cholecystectomy, appendicitis, and hernia operations. Additionally, we examined the impact of trainee autonomy, country development index, and hospital type on laparoscopy utilization. RESULTS: Among 68,659 total cases, only 616 (0.9%) were laparoscopic procedures. Notably, 34 cases were conducted during trainee external rotations in countries like the United Kingdom, Germany, and India. Gallbladder and appendix pathologies were most frequent among the 582 recorded laparoscopic cases performed in Africa. Laparoscopic cholecystectomy accounted for 29% (276 of 975 cases), laparoscopic appendectomy for 3% (76 of 2548 cases), and laparoscopic hernia repairs for 0.5% (26 of 5620 cases). Trainees self-reported lower autonomy for laparoscopic (22.5%) than open cases (61.5%). Laparoscopy usage was more prevalent in upper-middle-income (2.7%) and lower-middle-income countries (0.8%) compared with lower-income countries (0.5%) (p < 0.001). Private (1.6%) and faith-based hospitals (1.5%) showed greater laparoscopy utilization than public hospitals (0.5%) (p < 0.001). CONCLUSIONS: The study highlights the relatively low utilization of minimally invasive techniques in surgical training within the ECSA region. Laparoscopic cases remain a minority, with variations observed based on specific diagnoses. The findings suggest a need to enhance exposure to minimally invasive procedures to ensure well-rounded training and proficiency in these techniques.

RESUMEN

There is a lack of information on effective burn prevention strategies. The objective of this study was to examine a safe fireplace program, as a method of burn prevention, in a resource-limited setting. We conducted a qualitative, phenomenological study at a community health and development program for a rural population in Kenya. Semi-structured, in-depth interviews were conducted with a purposive sample of community health workers involved with the safe fireplace program. Data were reviewed iteratively and coded independently by two researchers using NVivo 12. The study included five participants. Reflections from participants fell into three main domains: (1) effective methods of education, (2) strategies to incorporate stakeholders, and (3) implementation challenges. The results of this study emphasize the importance of community engagement in implementing a successful burn injury prevention program in a resource-limited setting. The participants involved in this study reported that rather than focusing on resources outside the community, effective methods of education and strategies for incorporating stakeholders depended on involving peers and community leaders. The challenges to the program were similarly specific to community concerns about resources and maintenance. These findings provide information to guide future community health programs in creating successful models for burn prevention strategies in resource-limited areas.

RESUMEN

INTRODUCTION: Little is known about the impact of gender on emergency surgery within Kenya. Therefore, we aimed to investigate the association of gender on outcomes of postoperative complications, health care costs, and mortality. METHODS: We evaluated an established cohort of patients undergoing emergency gastrointestinal surgery in rural Kenya between January 1st, 2016 and June 30th, 2019. Utilizing logistic regression, we examined the association between self-reported patient gender and the outcomes of postoperative complications and mortality. A generalized linear model was created for total hospital costs, inflation-adjusted in international dollars purchasing power parity, to examine the impact of gender. Confounding factors were controlled by Africa Surgical Outcomes Study Surgical Risk Score. RESULTS: Among 484 patients reviewed, 149 (30.8%) were women. 165 (34.1%) patients developed complications, with women experiencing more than men (40.9% versus 31.0%; P = 0.03) and longer hospital stays (median 6 days (4-9) versus 5 (4-7); P = 0.02). After controlling for Africa Surgical Outcomes Study Surgical Risk Score, odds of developing complications for women were 1.67 (95% confidence interval: 1.09-2.55; P = 0.019) times higher than men, and the odds of death were 2.38 (95% confidence interval: 1.12-5.09; P = 0.025) times greater for women than men, despite similar failure-to-rescue rates and intensive care unit utilization. Total hospital costs were increased for women by 531 international dollars purchasing power parity (117-946; P = 0.012) when compared to men, attributed to longer lengths of stay. CONCLUSIONS: These findings demonstrate that a discrepancy exists between men and women undergoing emergency gastrointestinal surgery in our setting. Further exploration of the underlying causes of this inequity is necessary for quality improvement for women in rural Kenya.

RESUMEN

BACKGROUND: The SIMPL operative feedback tool is used in many U.S. surgical residency programs. However, the challenges of implementation and benefits of the web-based platform in low- and middle-income countries are unknown. The aim of this study was to evaluate implementation of SIMPL in a general surgery residency training program in Kenya. METHODS: SIMPL was pilot tested at Tenwek Hospital from January through December 2021. Participant perspectives of SIMPL were elicited through a survey and semi-structured interviews. Descriptive statistics were used to analyze survey data. Inductive qualitative content analysis of interview responses was performed by two independent researchers. RESULTS: Fourteen residents and six faculty (100% response rate) were included in the study and completed over 600 operative assessments. All respondents reported numerical evaluations and dictated feedback were useful. Respondents felt that SIMPL was easy to use, improved quality and frequency of feedback, helped refine surgical skills, and increased resident autonomy. Barriers to use included participants forgetting to complete evaluations, junior residents not submitting evaluations when minimally involved in cases, and technological challenges. Suggestions for improvement included expansion of SIMPL to surgical subspecialties and allowing senior residents to provide feedback to juniors. All respondents wanted to continue using SIMPL, and 90% recommended use at other programs. CONCLUSION: Residents and faculty at Tenwek Hospital believed SIMPL were a positive addition to their training program. There were a few barriers to use and suggestions for improvement specific to the training environment in Kenya, but this study demonstrates it is feasible to use SIMPL in settings outside the U.S. with the appropriate resources.

RESUMEN

BACKGROUND: Operative experience is a necessary part of surgical training. The College of Surgeons of East, Central, and Southern Africa (COSECSA), which oversees general surgery training programs in the region, has implemented guidelines for the minimum necessary case volumes upon completion of two (Membership) and five (Fellowship) years of surgical training. We aimed to review trainee experience to determine whether guidelines are being met and examine the variation of cases between countries. METHODS: Operative procedures were categorized from a cohort of COSECSA general surgery trainees and compared to the guideline minimum case volumes for Membership and Fellowship levels. The primary and secondary outcomes were total observed case volumes and cases within defined categories. Variations by country and development indices were explored. RESULTS: One hundred ninety-four trainees performed 69,283 unique procedures related to general surgery training. The review included 70 accredited hospitals and sixteen countries within Africa. Eighty percent of MCS trainees met the guideline minimum of 200 overall cases; however, numerous trainees did not meet the guideline minimum for each procedure. All FCS trainees met the volume target for total cases and orthopedics; however, many did not meet the guideline minimums for other categories, especially breast, head and neck, urology, and vascular surgery. The operative experience of trainees varied significantly by location and national income level. CONCLUSIONS: Surgical trainees in East, Central, and Southern Africa have diverse operative training experience. Most trainees fulfill the overall case volume requirements; however, further exploration of how to meet the demands of specific categories and procedures is necessary.

RESUMEN

BACKGROUND: Operative meaningful trainee autonomy is an essential component of surgical training. Reduced trainee autonomy is frequently attributed to patient safety concerns, but this has not been examined within Kenya. We aimed to assess whether meaningful trainee autonomy was associated with a change in patient outcomes. METHODS: We investigated whether meaningful trainee autonomy was associated with a change in severe postoperative complications and all-cause in-hospital mortality in a previously described cohort undergoing emergency gastrointestinal operations. Each operation was reviewed to determine the presence of meaningful autonomy, defined as "supervision only" from faculty. Comparisons were made between faculty-led cases and cases with meaningful trainee autonomy. Multilevel logistic regression models were created for the outcomes of mortality and complications with the exposure of meaningful trainee autonomy, accounting for fixed effects of the Africa Surgical Outcomes Study Risk Score and random effects of discharge diagnoses. RESULTS: After excluding laparoscopy (N = 28) and missing data (N = 3), 451 operations were studied, and 343 (76.1%) had meaningful trainee autonomy. Faculty were more involved in operations with older age, cancer, prior complications, and higher risk scores. On unadjusted analysis, meaningful trainee autonomy was associated with mortality odds of 0.32 (95% confidence interval: 0.17-0.58) compared with faculty-led operations. Similarly, the odds of developing complications were 0.52 (95% confidence interval: 0.32-0.84) with meaningful trainee autonomy compared with faculty-led operations. When adjusting for Africa Surgical Outcomes Study Score and clustering discharge diagnoses, the odds of mortality (odds ratio 0.58; 95% confidence interval: 0.27-1.2) and complication (odds ratio 0.83; 95% confidence interval: 0.47-1.5) were not significant. CONCLUSION: Our findings support that increasing trainee autonomy does not change patient outcomes in selected emergency gastrointestinal operations. Further, trainees and faculty appropriately discern patients at higher risk of complications and mortality, and the selective granting of trainee autonomy does not affect patient safety.

RESUMEN

PURPOSE: Radiology global health opportunities are expanding as more hospitals in low- and middle-income countries utilize CT. This creates opportunities for global health program building, education, service, and research. This study determines the diagnostic yield and variety of abdominopelvic CT diagnoses for abdominal pain in a US academic medical center (UW) compared to a rural Kenyan teaching hospital (Tenwek). METHODS: A retrospective, cross-sectional sequential sample of 750 adults from both hospitals who underwent abdominopelvic CT for abdominal pain from February 2019 through July 2020 was obtained. Exclusion criteria were trauma, cancer staging, and recent hospitalization or surgery. Patient age, sex, comparison studies, use of contrast, known cancer diagnosis, and CT diagnoses were compared. Negative exam rate, acute abdomen diagnosis, and new cancer diagnosis were recorded. Statistical analysis was performed using R. RESULTS: 750 UW patients met inclusion criteria (mean age 53.3 ± 20 years; 442 women) and 750 Tenwek patients met inclusion criteria (mean age 52.5 ± 18 years; 394 women). 72% of UW patients had comparison imaging compared to 6% of Tenwek patients. 11% (83/750) of UW patients had a known cancer diagnosis compared to 1% (10/750) of Tenwek patients. 39% of UW patients had a negative exam compared to 23% of Tenwek patients (p < 0.001). 58% of UW patients had an acute abdomen diagnosis compared to 38% of Tenwek patients (p < 0.001). 10 of the 15 top acute abdomen diagnoses were shared, but in different order of frequency. Diagnoses unique to UW were diverticulitis, constipation, stercoral colitis, and epiploic appendagitis. Diagnoses unique to Tenwek were tuberculosis and hydatidosis. 3% of UW patients received a new cancer diagnosis (7/19 metastatic), compared to 40% of Tenwek patients (153/303 metastatic) (p < 0.001). CONCLUSION: For adults undergoing CT for abdominal pain, there are differences in the prevalence of abdominal pain diagnoses, new cancer diagnosis, and negative exam rate between the rural Kenyan teaching hospital and the US academic medical center.

RESUMEN

OBJECTIVE: We aimed to evaluate the implementation of a dedicated Surgical critical care service (SCCS) on failure to rescue (FTR) rates in rural Kenya. SUMMARY BACKGROUND DATA: FTR adversely impacts perioperative outcomes. In the resource-limited contexts of low- and middle-income countries, emergency gastrointestinal surgery carries high morbidity and mortality rates. Quality improvement initiatives that decrease FTR rates are essential for improving perioperative care. METHODS: All patients who underwent emergency gastrointestinal surgery between January 2016 and June 2019 at Tenwek Hospital in rural Kenya were reviewed. Critical care capabilities were constant throughout the study period. A supervised surgical resident was dedicated to the daily care of critically ill surgical patients beginning in January 2018. The impact of the SCCS initiation on the outcome of FTR was evaluated, controlling for patient complexity via the African Surgical Outcomes Study Surgical Risk Score. RESULTS: A total of 484 patients were identified, consisting of 278 without and 206 with an active SCCS. A total of 165 (34.1%) patients experienced postoperative complications, including 49 mortalities (10.1%) yielding an FTR rate of 29.7%. The FTR rate decreased after SCCS implementation from 36.8% (95% CI: 26.7%-47.8%) to 21.8% (95% CI: 13.2%-32.6%) ( P = 0.035) despite an increase in the average patient African Surgical Outcomes Study score from 14.5 (95% CI, 14.1-14.9) to 15.2 (95% CI, 14.7-15.7) ( P =0.03). CONCLUSIONS: The implementation of an SCCS in rural Kenya resulted in decreased rates of FTR despite an increase in patient complexity and severity of critical illness.

RESUMEN

BACKGROUND: The financial burden of surgery is substantial worldwide. Postoperative complications increase costs in high-resource settings, but this is not well studied in other settings. Our objective was to review the financial impact of postoperative complications. METHOD: Patients undergoing emergency gastrointestinal operations at a center in Kenya were reviewed between January 2017 and June 2019. In a cost analysis, we ascertained the outcome of total hospital costs, adjusted for inflation, and converted to international dollars using purchasing power parities. Costs were analyzed for their association with a postoperative complication, defined using standardized criteria. We calculated the Africa Surgical Outcomes Study surgical risk scores and clustered for discharge diagnosis in a mixed-effects generalized linear model accounting for confounding factors related to costs and complications. RESULTS: A total of 361 individuals had cost data available. The cohort had 251 men (69.5%) and 110 women (30.5%) with a median age of 41 years (interquartile range: 29-57 years). A total of 122 (33.8%) patients experienced a postoperative complication with an overall all-cause mortality rate of 10.5%. The median total cost of hospitalization was 1,949 (interquartile range: 1,516-2,788) international dollar purchasing power parities. When controlling for patient factors and diagnoses, patients who did not develop complications had costs of 2,119 (95% confidence interval 1,898-2,340) compared to costs of 3,747 (95% confidence interval 3,327-4,167) for patients who developed a postoperative complication, leading to a 77% increase of 1,628 international dollar purchasing power parities for patients with complications. CONCLUSION: Our findings demonstrated a substantial financial burden generated by postoperative complications in patients undergoing emergency gastrointestinal operations. Reducing complications could allow cost savings, an important consideration in variable-resource settings.

RESUMEN

OBJECTIVE: We review the development, implementation, and initial outcomes of a semistructured interview process to assess the nontechnical skills of surgical residency applicants. DESIGN: In 2018, we restructured our residency selection interview process. Through semistructured faculty interviews, we sought to evaluate candidates along seven nontechnical skills (grit, ownership, rigor, teamwork, presence, impact, and organizational alignment). We plotted each candidate's scores on a radar plot for graphical representation and calculated the plot area of each candidate. We retrospectively evaluated 3 years of data, comparing the nontechnical skill scores of matriculants into the training program to those of nonmatriculants. SETTING: Tenwek Hospital is a 361-bed tertiary teaching and referral hospital in rural western Kenya with a 5-year general surgery residency program. PARTICIPANTS: Thirty-one applicants were interviewed over 3 years. Thirteen matriculated into the program. RESULTS: Scores for grit, (4.8 vs 3.9; p = 0.0004), impact (4.2 vs 3.5; p = 0.014), ownership (4.2 vs 3.6; p = 0.01), and organizational alignment (4.3 vs 3.8; p = 0.008) were significantly higher in matriculants. CONCLUSIONS: This semistructured interview process provides a robust and beneficial mechanism for assessing applicants' nontechnical skills, which may allow for the matriculation of more well-rounded candidates into surgical residency and, ultimately, surgical practice.

RESUMEN

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) and its asymptomatic precursor lesion, esophageal squamous dysplasia (ESD), are common in East Africa. It is unknown whether family history of esophageal cancer is a risk factor for both ESD and ESCC in Africa, and whether family members of affected persons should be screened. METHODS: We recruited 296 asymptomatic adult first-degree relatives of ESCC patients residing in southwestern Kenya. Participants completed questionnaires and underwent endoscopy with Lugol's iodine staining and biopsy to determine the prevalence of ESD. Prevalence comparisons were made with a prior population-based cohort from the same catchment area who also underwent Lugol's chromoendoscopy. RESULTS: Mean age was 40.7 years, compared to 62.7 years in the prior population study. The overall prevalence of ESD/ESCC among first-degree relatives was 14.7%, comparable to the background population prevalence of 14.4%, and this comparability remained even after adjusting for the different age distributions of the studies. Post-primary education was the only measured variable that was associated with a decreased risk of ESD/ESCC (adjusted OR=0.31, 95% CI: 0.11, 0.83). There was heterogeneity in the ESD prevalence across families, even after adjustments for varying age and other measured factors. CONCLUSIONS: The prevalence of esophageal squamous dysplasia among first-degree relatives of persons with ESCC was similar to that of the background population of southwestern Kenya; however, there was heterogeneity in ESD prevalence between families, suggesting other genetic or environmental factors may influence family prevalence. Further study of families with a high prevalence of ESD or ESCC is justified.

RESUMEN

Objective: We aimed to determine the impact of a standardized curriculum on learning outcomes for surgical trainees in East, Central, and Southern Africa (ECSA). Background: As surgical education expands throughout ECSA, there is a recognized need for a standardized curriculum. We previously described the design of a novel, large-scale, flipped-classroom, surgical curriculum for trainees in ECSA. Methods: In January 2020, the first year of curricular content for trainees of the College of Surgeons of ECSA was released, containing 11 monthly thematic topics, each with 2 to 5 weekly modular subtopics. We aimed to evaluate 3 outcomes utilizing data sources incorporated into the curriculum structure. Learner engagement was assessed by the number of trainees completing curriculum topics. User experience was evaluated using quantitative and qualitative feedback responses to embedded surveys for each content week. Curriculum impact on trainee examination performance was assessed by comparing certification examination scores stratified by the number of curricular topics each trainee completed. Results: Two hundred seventy-one trainees (96%) in 17 countries accessed at least 1 weekly module. Trainees completed a median of 9 topics (interquartile range: 6-10). The feedback survey response rate was 92% (5742/6233). Quantitative and qualitative responses were positive in overall module value (93.7% + 2.6%), amount of learning experienced (97.9% + 1.4%), confidence in achieving learning objectives (97.1% + 2.4%), and ease of use of the module (77.6% + 5.98%). Topic-related certification examination performance improved significantly with increased completion of thematic topics. Conclusions: A standardized surgical curriculum in ECSA demonstrated excellent trainee usage, positive feedback, and improved examination scores.

RESUMEN

Objective: We describe a structured approach to developing a standardized curriculum for surgical trainees in East, Central, and Southern Africa (ECSA). Summary Background Data: Surgical education is essential to closing the surgical access gap in ECSA. Given its importance for surgical education, the development of a standardized curriculum was deemed necessary. Methods: We utilized Kern's 6-step approach to curriculum development to design an online, modular, flipped-classroom surgical curriculum. Steps included global and targeted needs assessments, determination of goals and objectives, the establishment of educational strategies, implementation, and evaluation. Results: Global needs assessment identified the development of a standardized curriculum as an essential next step in the growth of surgical education programs in ECSA. Targeted needs assessment of stakeholders found medical knowledge challenges, regulatory requirements, language variance, content gaps, expense and availability of resources, faculty numbers, and content delivery method to be factors to inform curriculum design. Goals emerged to increase uniformity and consistency in training, create contextually relevant material, incorporate best educational practices, reduce faculty burden, and ease content delivery and updates. Educational strategies centered on developing an online, flipped-classroom, modular curriculum emphasizing textual simplicity, multimedia components, and incorporation of active learning strategies. The implementation process involved establishing thematic topics and subtopics, the content of which was authored by regional surgeon educators and edited by content experts. Evaluation was performed by recording participation, soliciting user feedback, and evaluating scores on a certification examination. Conclusions: We present the systematic design of a large-scale, context-relevant, data-driven surgical curriculum for the ECSA region.

RESUMEN

BACKGROUND: Cecal volvulus, which is a torsion involving the cecum, terminal ileum, and ascending colon around its own mesentery, results in a closed-loop obstruction. It is a rare reported cause of adult intestinal obstruction. This study aimed to review the clinical presentation, management, and outcomes at a rural, resource-limited referral center. METHODS: We performed a retrospective review of all patients with a diagnosis of cecal volvulus between January 1st, 2009 and December 31st, 2019 at Tenwek Hospital in Bomet, Kenya. The outcome of survival was compared by the time to presentation. Mortality was also compared with prior reports of intestinal obstruction at our institution. RESULTS: Thirteen patients were identified with a mean age of 52 years and a mean symptom duration of 5 days. All patients presented with abdominal pain and distension. Seven patients (54%) presented with perforation, gangrene, or gross peritoneal contamination. Identified risk factors were Ladds bands with malrotation, adhesions, and a sigmoid tumor. Procedures included primary resection and anastomosis (7), damage control (3) with anastomosis on second-look in 2 of these, simple surgical detorsion (1), and surgical detorsion and cecopexy (2). There were four mortalities (31%), of which all had delayed presentation with perforation and fecal contamination. Delays to presentation were associated with mortality (p = 0.03). Cecal volvulus resulted in increased perioperative mortality compared to all intestinal obstructions presenting to the institution (p < 0.0001). CONCLUSIONS: Cecal volvulus carries a high risk of mortality. A high index of suspicion and early consideration in the differential diagnosis of intestinal obstruction should be considered to reduce the mortality associated with the delay in preoperative diagnosis.

RESUMEN

BACKGROUND: Exposure to polycyclic aromatic hydrocarbons (PAHs) is a risk factor for esophageal squamous cell carcinoma (ESCC) in high-incidence areas of China, Iran and Brazil, but PAH assessments have not been conducted in East Africa, another ESCC hot spot. OBJECTIVE: To evaluate demographic or lifestyle factors associated with the PAH biomarker concentrations in the study population, and whether PAH metabolite concentrations showed any associations with esophageal precancerous lesions. METHODS: We recruited a community-based sample of 289 asymptomatic adults from a rural area of Kenya and performed Lugol's chromoendoscopy to detect esophageal squamous dysplasia (ESD); participants completed a questionnaire and provided a spot urine specimen. We analyzed urine for seven hydroxylated metabolites of naphthalene, fluorene, phenanthrene, and pyrene at the U.S. National Center for Environmental Health, and compared creatinine-corrected PAH metabolite concentrations with questionnaire data and the presence of ESD. RESULTS: PAH metabolite concentrations among never tobacco users in these rural Kenya residents were 2.4-28.1 times higher than those reported from never tobacco users in Iran, Brazil and the USA. Female sex, cooking indoors, having no post-primary education, and age <50, but not tobacco use, were positively and significantly associated with PAH metabolite concentrations. Almost all participants used wood as cooking fuel. Nine participants had advanced ESD. Adjusted logistic regression showed a significant association between 2-hydroxynaphthalene (OR = 4.19, 95%CI: 1.01-17.47) and advanced ESD. All other PAH metabolites had positive but non-significant associations with advanced ESD. CONCLUSIONS: Urinary PAH metabolite concentrations among never tobacco users are markedly higher in this group from Kenya than in other populations and are associated with indoor cooking with wood on open, unvented stoves. These metabolite concentrations were also associated with the presence of advanced esophageal dysplasia. Our findings underline the importance of assessing alternative cooking conditions to reduce PAH exposure in this population.

RESUMEN

BACKGROUND: High-income countries have increased the use of simulation-based training and assessment for surgical education. Learners in low- and middle-income countries may have different educational needs and levels of autonomy but they and their patients could equally benefit from the procedural training simulation provides. We sought to characterize the current state of surgical skills simulation in East, Central, and Southern Africa and determine residents' perception and future interest in such activities. METHODS: A survey was created via collaboration and revision between trainees and educators with experiences spanning high-income countries and low- and middle-income countries. The survey was administered on paper to 76 trainees (PGY2-3) who were completing the College of Surgeons of East, Central, and Southern Africa (COSECSA) Membership of the College of Surgeons examination in Kampala, Uganda in December 2019. Data from paper responses were summarized using descriptive statistics and frequencies. RESULTS: We received responses from 43 trainees (57%) from 11 countries in sub-Saharan Africa who participated in the examination. Fifty-eight percent of respondents reported having dedicated space for surgical skills simulation training, and most (91%) had participated in some form of simulation activity at some point in their training. However, just 16% used simulation as a regular part of training. The majority of trainees (90%) felt that surgical skills learned in simulation were transferrable to the operating room and agreed it should be a required part of training. Seventy-one percent of trainees felt that simulation could objectively measure technical skills, and 73% percent of respondents agreed that simulation should be integrated into formal assessment. However, residents split on whether proficiency in simulation should be achieved prior to operative experience (54%) and if nontechnical skills could be measured (51%). The most common cited barriers to the integration of surgical simulation into residents' education were lack of suitable tools and models (85%), funding (73%), and maintenance of facilities (49%). CONCLUSIONS: Residents from East, Central, and Southern Africa strongly agree that simulation is a valuable educational tool and ought to be required during their surgical residency. Barriers to achieving this goal include availability of affordable tools, adequate funding and confidence in the value of the educational experience. Trainees affirm further efforts are necessary to make simulation more widely available in these contexts.

RESUMEN

BACKGROUND: The education of surgical trainees is ideally designed to produce surgeons with both confidence and competence. This involves the development of autonomy in the operating room. Factors associated with autonomy and entrustment have been studied in high-resource settings. In a resource-limited context, where autonomy is solely at the discretion of faculty, and there are fewer external constraints to restrict it, we hypothesized that assessment of a trainee's performance would be dependent upon reported confidence levels of both faculty and trainees in those trainees' abilities. MATERIALS AND METHODS: At a teaching hospital in rural Kenya, operative experience surveys were administered to eleven general surgery trainees (PGY1-5) and six faculty paired dyads immediately following operative procedures in May 2016 to elicit self-reported assessments of confidence, hesitation, and ability as measured by the Zwisch Scale. We examined factors related to learning and used dyadic structural equation models to understand factors related to the assessment of ability. RESULTS: There were 107 paired surveys among 136 trainees and 130 faculty evaluations. Faculty scrubbed into 76 (72%) cases. In comparison to trainees, faculty were more likely to give a higher average score for confidence (4.08 versus 3.90; P value: 0.005), a lower score for hesitation (2.67 versus 2.84; P value: 0.001), and a lower score for the ability to perform the operation independently (2.73 versus 3.02; P value: 0.01). Faculty and trainee perceptions of hesitation influenced their ability scores. Trainee hesitation (OR 12.1; 1.2-127.6, P = 0.04) predicted whether trainees reported experiencing learning. CONCLUSIONS: Between trainees and faculty at a teaching program in rural Kenya, assessment scores of confidence, hesitation, and ability differ in value but remain fairly correlated. Hesitation is predictive of ability assessment, as well as self-reported learning opportunities. Focus upon identifying when trainees hesitate to proceed with a case may yield important educational opportunities.

RESUMEN

BACKGROUND: Gastrointestinal endoscopy (GIE) is not routinely accessible in many parts of rural Africa. As surgical training expands and technology progresses, the capacity to deliver endoscopic care to patients improves. We aimed to describe the current burden of gastrointestinal (GI) disease undergoing GIE by examining the experience of surgical training related to GIE. METHODS: A retrospective review was conducted on GIE procedures performed by trainees with complete case logs during 5-year general surgery training at Pan-African Academy of Christian Surgeons (PAACS) sites. Cases were classified according to diagnosis and/or indication, anatomic location, intervention, adverse events, and outcomes. Comparisons were performed by institutional location and case volumes. Analysis was performed for trainee self-reported autonomy by post-graduate year and case volume experience. RESULTS: Twenty trainees performed a total of 2181 endoscopic procedures. More upper endoscopies (N = 1,853) were performed than lower endoscopies (N = 325). Of all procedures, 546 (26.7%) involved a cancer or mass, 267 (12.2%) involved a report of blood loss, and 452 (20.7%) reported pain as a component of the diagnosis. Interventions beyond biopsy were reported in 555 (25%) procedures. Esophageal indications predominated the upper endoscopies, particularly esophageal cancer. Trainees in high-volume centers and in East Africa performed more interventional endoscopy and procedures focused on esophageal cancer. Procedure logs documented adverse events in 39 cases (1.8% of all procedures), including 16 patients (0.8%) who died within 30 days of the procedure. Self-reported autonomy improved with both increased endoscopy experience and post-graduate year. CONCLUSIONS: GIE is an appropriate component of general surgery residency training in Africa, and adequate training can be provided, particularly in upper GI endoscopy, and includes a wide variety of endoscopic therapeutic interventions.

RESUMEN

Burn injury represents a substantial burden of disease in resource-limited settings. Kenya has no formal trauma system and referral practices for burn injuries are not well understood. The purpose of this study was to determine the factors associated with burn injury referrals in rural Kenya. A retrospective chart review was conducted for patients with burn injury from January 1, 2014 to December 31, 2017 at a 300-bed faith-based, teaching hospital in southwest Kenya. Bivariate analysis compared referred and non-referred patients. Multivariable logistic regression was used to assess the association between burn severity and odds of referral adjusting for age, sex, insurance, time from injury to arrival, and estimated travel time from home to hospital. The study included 171 patients with burn injury; 11 patients were excluded due to missing referral data. Of the 160 patients, 31.9% (n = 51) were referred. Referral patients had higher average total body surface area burn (23.1 ± 2.4% vs 11.1 ± 1.2%, P < .001), were more likely to have full-thickness burns (41.3% vs 25.5%, P = .05), and less likely to present to the referral hospital within 24 hours after injury (47.8% vs 73.0%, P = .005). Referral patients had longer travel time to hospital (90+ min: 52.9% vs 22.0%, P < .001). Odds of referral increased 1.62 times (95% confidence interval: 1.19-2.22) for every 10% increase in total body surface area burn. Without a coordinated trauma system, referrals represent a substantial portion of burn injury patients at a hospital in rural Kenya. Referred patients present with more severe burns and experience delays to presentation.

RESUMEN

BACKGROUND: Perioperative pain management is an essential component to improving patient outcomes. Measurement and description of pain are challenging and vary in different contexts. The objective of this study was to assess the utility of self-reporting via visual analogue scales using the Jerrycan visual analogue scale in the assessment of post-operative pain and to validate the use of this novel scale compared to standard pain scales. MATERIALS AND METHODS: Two hundred and forty-one inpatients who underwent surgical procedures were prospectively assessed for post-operative pain over a 12-month period from February 2016 to January 2017. Participants included patients who underwent general surgery, orthopedic and obstetrics/gynecology procedures. On post-operative day one, four scales were assessed: Verbal scale, Hands scale, Faces scale and Jerrycan scale, each ranging from 0-5. Scores for each scale were recorded, and agreements between scales were calculated using kappa values and Spearman's rank coefficients. RESULTS: The mean age was 34.8 years and more female subjects were evaluated (68%). The majority received spinal anesthesia (61%). The mean pain score was 2.5 for all scales. The Jerrycan (0.50) and Faces scales (0.43) had moderate agreements with the Verbal scale. Participants preferred the Jerrycan Pain Scale. CONCLUSION: The Jerrycan pain scale had comparable scores and reasonable agreement with 3 other pain scales among a cohort of post-operative patients. Patient preference and ease of use of the Jerrycan scale may impact assessment and management of pain in a rural African setting. This scale may be adapted for use in similar resource settings for post-operative pain management.
