Technical Perspective for Video Based Assessment of Surgeries in Low-Resource Settings.

OBJECTIVE: Scalable digital learning environments are essential to sustain surgical training programs worldwide. Detailed images of surgeries enriched with educational annotations are vital to train the eyes of the learners. Here, we report a low-cost method, deployed in a low-resource setting in West Africa, which may contribute to the growth of use in open-sourced digital surgical resources world-wide. DESIGN: This paper is based on the authors participatory and observational experiences creating surgical video content by way of recording surgical procedures and reflecting on field notes and video content. All surgeries were recorded between January and December 2018. SETTING: Masanga Hospital, a rural district hospital in Sierra Leone, West Africa. PARTICIPANTS: Thirty-five patients undergoing inguinal hernia repair, elective caesarian section, salpingectomy, bowel resection, hydrocele repair, or below-knee amputation consented for recording their surgical procedure and using the anonymized material for educational purposes. RESULTS: This manual for non-professional cinematographers provides chronological steps for shooting a surgical procedure in a low-resource setting. Recording a surgical procedure to explain surgical techniques, and perform quality assessment through error analysis and coaching requires more than just point-and-shoot. While taking into account local customs and possibilities, practical tips were provided to prepare for the set-up, and recording of a surgical procedure in a low-resourced setting. CONCLUSION: Commercially available digital video technology allows for filming high-quality surgical procedures for educational purposes at rural district hospitals in a low-resource setting.

Inguinal hernia surgery learning curves by associate clinicians.

BACKGROUND: Open inguinal hernia repair is the most commonly performed procedure in general surgery in sub-Saharan Africa, but data on its learning curve are lacking. This study evaluated the learning curve characteristics to improve surgical training and enable scaling up hernia surgery in low- and middle-income countries. METHODS: Logbook data of associate clinicians enrolled in a surgical training program in Sierra Leone were collected and their first 55 hernia surgeries following the Bassini technique (herniorrhaphies) were analyzed in cohorts of five cases. Studied variables were gradient of decline of operating time, variation in operating time, and length of stay (LOS). Eleven subsequent cohorts of each five herniorrhaphies were investigated. RESULTS: Seventy-five trainees enrolled in the training program between 2011 and 2020 were eligible for inclusion. Thirty-one (41.3%) performed the minimum of 55 herniorrhaphies, and had also complete personal logbook data. Mean operating times dropped from 79.6 (95% CI 75.3-84.0) to 48.6 (95% CI 44.3-52.9) minutes between the first and last cohort, while standard deviation in operating time nearly halved to 15.4 (95% CI 11.7-20.0) minutes, and LOS was shortened by 3 days (8.5 days, 95%CI 6.1-10.8 vs. 5.4 days, 95% 3.1-7.6). Operating times flattened after 31-35 cases which corresponded with 1.5 years of training. CONCLUSIONS: The learning curve of inguinal hernia surgery for associate clinicians flattens after 31-35 procedures. Training programs can be tailored based on this finding. The recorded learning curve may serve as a baseline for future training techniques.

Chronic wounds in Sierra Leone: pathogen spectrum and antimicrobial susceptibility.

PURPOSE: Chronic wounds are frequently caused by, or super-infected with, a broad spectrum of bacteria. To guide treatment, healthcare providers need to know the bacterial spectrum and antimicrobial resistance rates to be anticipated. As these data are largely missing for Sierra Leone, we performed a microbiological study on chronic wound infections. METHODS: Wound swabs were analysed for bacteria using culture-based methods. Antimicrobial susceptibility testing was done with Vitek2® automated system and EUCAST clinical breakpoints. Selected resistance phenotypes were confirmed by molecular methods (e.g. mecA/C) and genotyping. RESULTS: Of 163 included patients, 156 (95.7%) had a positive wound culture. Pseudomonas aeruginosa (n = 75), Klebsiella pneumoniae (n = 42), Proteus mirabilis (n = 31), Staphylococcus aureus-related complex (n = 31) were predominant. Among Gram-negative rods, resistance rates were high for piperacillin/tazobactam (3-67%), cefotaxime (19-71%), and ciprofloxacin (13-60%). Among isolates of the S. aureus-related complex, 55% were methicillin resistant (CC8, PVL-negative). CONCLUSION: The high antimicrobial resistance rates in bacteria from chronic wounds strongly speaks against the use of empirical systemic antibiotic therapy if patients do not show signs of systemic infections, and supports the strategy of local wound care.
