Creation, Implementation, and Assessment of a General Thoracic Surgery Simulation Course in Rwanda

Systematic Review of Procedural Skill Simulation in Health Care in Low- and Middle-Income Countries

SUMMARY STATEMENT

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.From 5371 screened articles, 262 were included in this review. All included studies were in English. Most studies were observational cohort studies (72.9%) and focused on obstetrics and neonatal medicine (32.4%). Most measured outcome was the process of task performance (56.5%). Several studies mentioned cost (38.9%) or sustainability (29.8%). However, few articles included actual monetary cost information (11.1%); only 1 article assessed cost-effectiveness. Based on our review, future research of procedural skill simulation in LMICS should focus on more rigorous research, cost assessments, and on less studied areas.

Creation and validation of a novel low-cost dry lab for early resident training and assessment of robotic prostatectomy technical proficiency

Purpose

To evaluate the preliminary validity and acceptability of a low-cost low-fidelity robotic surgery dry lab for training and assessing residents' technical proficiency with key robotic radical prostatectomy steps.

Materials and methods

Three standardized inanimate tasks were created to simulate the radical prostatectomy steps of posterior dissection, neurovascular bundle release, and urethrovesical anastomosis. Urology trainees and faculty at a single institution completed and evaluated each dry lab task. Construct validity was evaluated by comparing task completion times and Global Evaluative Assessment of Robotic Skills scores across four participant cohorts: medical students (n = 5), junior residents (n = 5), senior residents (n = 5), and attending surgeons (n = 7). Content validity, face validity, and acceptability were evaluated through a posttask survey using a 5-point Likert scale.

Results

There was a significant difference in the individual and composite task completion times and Global Evaluative Assessment of Robotic Skills scores across all participant cohorts (all p < 0.01). The model was rated favorably in terms of its content validity and acceptability for use in residency training. However, model realism, compared with human tissue, was poorly rated. The dry lab production cost was less than US $25.

Conclusions

This low-cost procedure-specific dry lab demonstrated evidence of content validity, construct validity, and acceptability for simulating key robotic prostatectomy technical steps and can be used to augment robot-assisted laparoscopic prostatectomy surgical training.

Current Status of Simulation in Thoracic Surgical Training

BACKGROUND

Simulation is playing an increasingly important role in surgical training but is not yet a mandatory part of most surgical curricula. A simulator must undergo rigorous validation to verify it as a reliable tool. The aim of this study was to review the literature to identify simulators that are currently available to augment thoracic surgical training and to analyze any evidence supporting or validating them.

METHODS

A literature search of the MEDLINE (1946 to November 2022) and Embase (1947 to November 2022) databases was performed to identify simulators for basic skills and procedures in thoracic surgery. A selection of keywords were used to perform the literature search. After identification of appropriate articles, data were extracted and analyzed.

RESULTS

Thirty-three simulators were found in 31 articles. Simulators for basic skills (n = 13) and thoracic lobectomy (n = 13) were most commonly described, followed by miscellaneous (n = 7). Most models were of a hybrid modality (n = 18). Evidence of validity was established in 48.5% (n = 16) of simulators. In total, 15.2% (n = 5) of simulators had 3 or more elements of validity demonstrated, and only 3.0% (n = 1) accomplished full validation.

CONCLUSIONS

Numerous simulators of varying modality and fidelity exist for a variety of thoracic surgical skills and procedures, although validation evidence is frequently inadequate. Simulation models may be able to provide training in basic surgical and procedural skills; however, further assessment of validity needs to be undertaken before consideration of their integration into training programs.

Simulation in thoracic surgery-A mini review of a vital educational tool to maximize peri-operative care and minimize complications

Thoracic surgery is an increasingly expanding field, and the addition of national screening programs has resulted in increasing operative numbers and complexity. Thoracic surgery overall has an approximately 2% mortality and 20% morbidity with common specific complications including persistent air leak, pneumothorax, and fistulas. The nature of the surgery results in complications being unique to thoracic surgery and often very junior members of the surgical team feel underprepared to deal with these complications after very little exposure during their medical school and general surgical rotations. Throughout medicine, simulation is being increasingly used as a method to teach the management of complicated, rare, or significant risk occurrences and has shown significant benefits in learner confidence and outcomes. In this mini review we explain the learning theory and benefits of simulation learning. We also discuss the current state of simulation in thoracic surgery and its potential future in aiding complication management and patient safety.

Teaching Thoracic Surgery in a Low-Resource Setting:: Creation of a Simulation Curriculum in Rwanda

Surgical education and global health partnerships have evolved over the years. There is growing recognition of the importance of in-country training of surgeons and surgeon specialists in low-resource settings to support the local health care system. There are numerous ways in which high-income partners can support local training programs. The Human Resources for Health program was initiated in 2012 to advance in-country training of health care professionals in Rwanda. As there was a limited in-country operative experience for teaching general thoracic surgery, simulation models were developed, influenced by a prior course developed for American cardiothoracic trainees. Local Rwandan faculty were engaged. Adaptations from the American version included constructing models from inexpensive materials to make the simulation more feasible in the Rwanda setting.

General Thoracic Surgery in Rwanda: An Assessment of Surgical Volume and of Workforce and Material Resource Deficits

BACKGROUND

Benchmarking operative volume and resources is necessary to understand current efforts addressing thoracic surgical need. Our objective was to examine the impact on thoracic surgery volume and patient access in Rwanda following a comprehensive capacity building program, the Human Resources for Health (HRH) Program, and thoracic simulation training.

METHODS

A retrospective cohort study was conducted of operating room registries between 2011 and 2016 at three Rwandan referral centers: University Teaching Hospital of Kigali, University Teaching Hospital of Butare, and King Faisal Hospital. A facility-based needs assessment of essential surgical and thoracic resources was performed concurrently using modified World Health Organization forms. Baseline patient characteristics at each site were compared using a Pearson Chi-squared test or Kruskal-Wallis test. Comparisons of operative volume were performed using paired parametric statistical methods.

RESULTS

Of 14,130 observed general surgery procedures, 248 (1.76%) major thoracic cases were identified. The most common indications were infection (45.9%), anatomic abnormalities (34.4%), masses (13.7%), and trauma (6%). The proportion of thoracic cases did not increase during the HRH program (2.07 vs 1.78%, respectively, p = 0.22) or following thoracic simulation training (1.95 2013 vs 1.44% 2015; p = 0.15). Both university hospitals suffer from inadequate thoracic surgery supplies and essential anesthetic equipment. The private hospital performed the highest percentage of major thoracic procedures consistent with greater workforce and thoracic-specific material resources (0.89% CHUK, 0.67% CHUB, and 5.42% KFH; p < 0.01).

CONCLUSIONS AND RELEVANCE

Lack of specialist providers and material resources limits thoracic surgical volume in Rwanda despite current interventions. A targeted approach addressing barriers described is necessary for sustainable progress in thoracic surgical care.
