Low- and middle-income countries (LMICs) have adopted procedural skill simulation, with researchers increasingly investigating simulation efforts in resource-strained settings. We aim to summarize the current state of procedural skill simulation research in LMICs focusing on methodology, clinical area, types of outcomes and cost, cost-effectiveness, and overall sustainability. We performed a comprehensive literature review of original articles that assessed procedural skill simulation from database inception until April 2022.

Background: Small bowel obstruction management has evolved to incorporate the Gastrografin challenge. We expanded its use to the emergency department observation unit, potentially avoiding hospital admission for highly select small bowel obstruction patients. We hypothesized that the emergency department observation unit small bowel obstruction protocol would reduce admissions, costs, and the total time spent in the hospital without compromising outcomes.

Although the use of video-assisted thoracoscopic surgery (VATS) for resection of lung metastases has increased, surgeons still advocate for open resection as it permits palpation of lesions that may be missed on imaging. This study aimed to compare the utilization of open thoracotomy versus VATS over time and determine if the use of VATS changes perioperative outcomes. Using the Kids' Inpatient Database (2006, 2009, 2012, 2016), we identified children (age ≤20) with a diagnosis of secondary lung cancer with either lobectomy or sublobar resection coded during the same admission.

Article Synopsis
  • The study explored how Behavioral Health Disorders (BHDs) impact outcomes for injured children aged 5-15, finding that a notable percentage of these kids had BHDs.
  • Among the 69,305 injured children analyzed, those with BHDs were more likely to have severe injuries and suffer from intentional and penetrating trauma, including a higher incidence of gunshot wounds.
  • Despite these factors, children with BHDs showed a lower risk of in-hospital mortality compared to those without, indicating a complex relationship between BHDs and trauma outcomes that requires further investigation, especially regarding prevention strategies.

  • The study evaluated pediatric gastrointestinal ulcer disease in children under 21 years old from 1990 to 2019, focusing on the characteristics of immunosuppressed patients compared to immunocompetent ones.
  • Out of 129 cases reviewed, 19 patients were immunosuppressed, and they had a higher rate of requiring surgical intervention (47.3%) compared to immunocompetent patients (16.4%).
  • The research concluded that immunosuppressed children face more surgical complications and longer hospital stays, highlighting the need for better ulcer prevention strategies and prompt evaluation of abdominal pain in these patients.*

Article Synopsis
  • The study examined the use of CT scans for pediatric trauma patients at a trauma center in South Africa, noting that over half of the children admitted received CT imaging.
  • Results indicated that many CT scans returned normal findings, with a significant portion not leading to further surgical intervention, especially in cases of head and abdominal scans.
  • The authors suggest that the high rate of CT usage and normal outcomes indicate possible over-reliance on this imaging technique in a middle-income country setting.

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.
