RESUMO
There is evidence that demonstrates that teaching preclinical and clinical material can have numerous benefits for both students and teachers, with the majority of literature focusing on peer medical student teaching. There is a dearth of literature exploring the benefit of medical students teaching undergraduate, pre-health professional students and using clinical cases in this setting. We explore our implementation of a team-based learning curriculum built around clinical cases to teach advanced physiology and introduce pathology, pharmacology, and interprofessional collaboration for pre-health students. This course was entirely taught by medical students. Course evaluations and future implications are discussed.

INTRODUCTION: Improving surgical care in a resource-limited setting requires the optimization of operative capacity, especially at the district hospital level. METHODS: We conducted an analysis of the acute care surgery registry at Salima District Hospital in Malawi from June 2018 to November 2019. We examined patient characteristics, interventions, and outcomes. Modified Poisson regression modeling was used to identify risk factors for transfer to a tertiary center and mortality of patients transferred to the tertiary center. RESULTS: Eight hundred eighty-eight patients were analyzed. The most common diagnosis was skin and soft tissue infection (SSTI) at 35.9%. 27.5% of patients were transferred to Salima District Hospital, primarily from health centers, with a third for a diagnosis of SSTI. Debridement of SSTI comprised 59% of performed procedures (n = 241). Of the patients that required exploratory laparotomy, only 11 laparotomies were performed, with 59 patients transferred to a tertiary hospital. The need for laparotomy conferred an adjusted risk ratio (RR) of 10.1 (95% confidence interval [CI] 7.1, 14.3) for transfer to the central hospital. At the central hospital, for patients who needed urgent abdominal exploration, surgery had a 0.16 RR of mortality (95% CI 0.05, 0.50) while time to evaluation greater than 48 h at the central hospital had a 2.81 RR of death (95% CI 1.19, 6.66). CONCLUSIONS: Despite available capacity, laparotomy was rarely performed at this district hospital, and delays in care led to a higher mortality. Optimization of the district and health center surgical ecosystems is imperative to improve surgical access in Malawi and improve patient outcomes.

INTRODUCTION: The burden of surgical diseases is high in sub-Saharan Africa. Despite limitations to surgical care access, health-related quality of life (HRQoL) data following surgical intervention are scarce. METHODS: We performed a 3-month prospective observational study of adult patients undergoing an abdominal operation. We administered the Patient-Reported Outcome Measurement Information System (PROMIS)-25 and Index of Independence in Activities of Daily Living questionnaire preoperatively (to postoperative day [POD] #1), POD#7, and POD#30. PROMIS-25 HRQoL domains were measured and converted to standardized T-scores (median 50, minimal important clinical difference 3). RESULTS: Of the 117 laparotomy patients who were enrolled, 89 (76.1%) were male with a median age of 39 years (IQR 27-54). Operations were primarily for intestinal volvulus (n = 30, 28.3%) and intestinal perforation (n = 29, 27.4%). We completed a total of 80 (68.4%), 95 (81.2%), and 77 (65.8%) surveys preoperatively, at POD#7, and POD#30, respectively. Preoperatively patients showed high median levels of anxiety (56), depression (60), fatigue (63), and pain interference (62), which all improved postoperatively. Mobility was poor preoperatively (31) and showed improvement during recovery but remained poor [POD#7: 32, POD#30: 39]. Pain intensity was high (10/10) preoperatively and improved to 3/10 by POD#30. Patients with complications compared to those without had clinically significant worse HRQoL in all domains measured by POD#30. DISCUSSION: Abdominal surgery patients in a resource-limited setting present with poor HRQoL, which improves postoperatively. Mobility remained poor throughout follow-up despite improved pain scores. Our findings highlight the need for improved HRQoL and pain control among surgical patients.

BACKGROUND: In sub-Saharan Africa, trauma is a leading cause of mortality in people less than 45 years. Injury mechanism and cause of death are difficult to characterize in the absence of pre-hospital care and a trauma surveillance database. Pre-hospital deaths (PHD) and in-hospital deaths (IHD) of trauma patient were compared to elucidate comprehensive injury characteristics associated with mortality. METHODS: A retrospective, descriptive analysis of adults (≥ 13 years) presenting to Kamuzu Central Hospital in Lilongwe, Malawi, from February 2008 to May 2018 was performed. Utilizing an emergency department-based trauma surveillance database, univariate and bivariate analysis was performed to compare patient and injury characteristics of pre-hospital and in-hospital deaths. A Poisson multivariate regression was performed, predicting the relative risk of PHD. RESULTS: Between February 2008 and May 2018, 131,020 adult trauma patients presented to KCH, with 2007 fatalities. Of those patients, 1130 (56.3%) and 877 (43.7%) were PHD and IHD, respectively. The majority were men, with a mean age of 33.4 years (SD 12.1) for PHD and 37.4 years (SD 15.5) for IHD, (p < 0.001). Head injuries (n = 545, 49.2% vs. n = 435, 49.7%) due to assaults (n = 255, 24.7% vs. n = 178, 21.8%) and motor vehicle collisions (MVC) (n = 188, 18.2% vs. n = 173, 21.2%) were the leading cause of both groups (PHD vs. IHD). Transportation to the hospital was primarily police (n = 663, 60.1%) for PHD and ambulance (n = 401, 46.4%) for IHD. Patients who were transported to KCH by the police (RR 1.97, 95% 1.52-2.55, p < 0.001) when compared to transport via minibus had an increased relative risk of PHD. Patients with a head or spine (RR 1.32, 95% CI 1.34-1.53, p < 0.001), chest (RR 1.34, 95% CI 1.11-1.62, p = 0.002) or abdomen and pelvis (RR 1.30, 95% CI 1.14-1.53, p = 0.004) when compared to extremity injury had an increased relative risk of PHD. CONCLUSIONS: Head injury from assaults and MVC is the leading cause of PHD and IHD in Malawi. The majority of patients are transported via police if PHD. Of IHD patients, the majority are transported by ambulance, most often from outside hospitals. Both are consistent with the absence of a pre-hospital system in Malawi. Improving pre-hospital care, with a particular focus on head injury and strategies for vehicular injury prevention within a trauma system, will reduce adult trauma mortality in Malawi.

BACKGROUND: Intestinal volvulus is a common cause of mechanical intestinal obstruction (MIO) in Africa. Sigmoid volvulus has been well characterized in both high-income and low-income countries, but there is also a predilection for small bowel volvulus in sub-Saharan Africa. METHODS: An analysis was performed of the Kamuzu Central Hospital Acute Care Surgery Registry from 2013 to 2019 on patients presenting with intestinal volvulus. Bivariate analysis was performed for covariates based on the intestinal volvulus type. Multivariate Poisson regression models estimated the relative risk of volvulus and mortality. RESULTS: A total of 4352 patients were captured in the registry. Overall, 1037 patients (23.8%) were diagnosed with MIO. Intestinal volvulus accounted for 499 (48.1%) of patients with MIO. Sigmoid volvulus, midgut volvulus, ileosigmoid knotting, and cecal volvulus accounted for 57.7% (n = 288), 19.8% (n = 99), 20.8% (n = 104), and 1.6% (n = 8), respectively. Mean age was 46.8 years (SD 17.2) with a male preponderance (n = 429, 86.0%) and 14.8% (n = 74) mortality. Overall, the most common operations performed were large bowel (n = 326, 74.4%) and small bowel (n = 76, 16.7%) resections with 18.0% (n = 90) ostomy formation. Upon regression modeling, the relative risk for volvulus was 2.7 times higher in men than women after controlling for season and age. There was no statistically significant difference in the relative risk of mortality based on the type of volvulus. CONCLUSION: Volvulus is a significant cause of primary bowel obstruction in sub-Saharan Africa. Type of intestinal volvulus is not associated increased risk of mortality. Reasons for increases in the incidence of small bowel volvulus are still largely undetermined.

Patients experience delays in emergency surgical care. Our 3-month mixed-methods observational prospective study examined the duration of in-hospital delays (IHDs) to emergency surgery at a tertiary hospital in Malawi and perceived reasons for such delay, assessing the correlation between surgery and anesthesia. Delays over two hours occurred in the majority, and almost 20% waited over twelve hours. However, we found no correlation between surgeons and anaesthetists in the perceived reasons for In-hospital delays to emergency surgical care.

BACKGROUND: More than 90% of trauma mortality occurs in low- and middle-income countries, especially in sub-Saharan Africa. Head injury is the primary driver of trauma mortality in the prehospital and in-hospital setting. METHODS: An observational study was performed on patients presenting with traumatic brain injury (TBI) from October 2016 through May 2017 at Kamuzu Central Hospital, Malawi. Bivariate analysis and logistic regression were performed to determine the odds of favorable functional outcomes and mortality after controlling for significant covariates. RESULTS: Of the 356 patients with TBI, 72 (20.2%) were children <18 years of age. Males comprised 202 (87.1%) and 46 (63.9%) of the adult and pediatric cohorts, respectively. Motor vehicle crash was the leading etiology in adults and children. There was no significant difference between adult and pediatric Glasgow Coma Scale score on admission, 10.8 ± 3.9 versus 10.9 ± 3.5, respectively (P = 0.8). More adult (n = 76, 32.3%) than pediatric (n = 13, 18.1%) patients died. On multivariable analysis, pediatric patients were more likely to have a favorable outcome defined by a Glasgow Outcome Scale of good recovery or moderate disability (odds ratio 3.70, 95% confidence interval 1.22-11.17, P = 0.02) and were less likely to die after TBI (odds ratio 0.29, 95% confidence interval 0.09-0.93, P = 0.04). CONCLUSIONS: We show a survival advantage and better functional outcomes in children following TBI. This may be attributable to increased resiliency to TBI in children or the prioritization of children in a resource-poor environment. Investments in neurosurgical care following TBI are needed to improve outcomes.
