An Evaluation of the Role of Simulation Training for Teaching Surgical Skills in Sub-Saharan Africa.

BACKGROUND: An estimated 5 billion people worldwide lack access to any surgical care, whilst surgical conditions account for 11-30% of the global burden of disease. Maximizing the effectiveness of surgical training is imperative to improve access to safe and essential surgical care on a global scale. Innovative methods of surgical training have been used in sub-Saharan Africa to attempt to improve the efficiency of training healthcare workers in surgery. Simulation training may have an important role in up-scaling and improving the efficiency of surgical training and has been widely used in SSA. Though not intended to be a systematic review, the role of simulation for teaching surgical skills in Sub-Saharan Africa was reviewed to assess the evidence for use and outcomes. METHODS: A systematic search strategy was used to retrieve relevant studies from electronic databases PubMed, Ovid, Medline for pertinent articles published until August 2016. Studies that reported the use of simulation-based training for surgery in Africa were included. RESULTS: In all, 19 articles were included. A variety of innovative surgical training methods using simulation techniques were identified. Few studies reported any outcome data. Compared to the volume of surgical training initiatives that are known to take place in SSA, there is very limited good quality published evidence for the use of simulation training in this context. CONCLUSIONS: Simulation training presents an excellent modality to enhance and improve both volume and access to high quality surgical skills training, alongside other learning domains. There is a desperate need to meticulously evaluate the appropriateness and effectiveness of simulation training in SSA, where simulation training could have a large potential beneficial impact. Training programs should attempt to assess and report learner outcomes.

Hospital-acquired listeriosis linked to a persistently contaminated milkshake machine.

One case of hospital-acquired listeriosis was linked to milkshakes produced in a commercial-grade shake freezer machine. This machine was found to be contaminated with a strain of Listeria monocytogenes epidemiologically and molecularly linked to a contaminated pasteurized, dairy-based ice cream product at the same hospital a year earlier, despite repeated cleaning and sanitizing. Healthcare facilities should be aware of the potential for prolonged Listeria contamination of food service equipment. In addition, healthcare providers should consider counselling persons who have an increased risk for Listeria infections regarding foods that have caused Listeria infections. The prevalence of persistent Listeria contamination of commercial-grade milkshake machines in healthcare facilities and the risk associated with serving dairy-based ice cream products to hospitalized patients at increased risk for invasive L. monocytogenes infections should be further evaluated.

Snapshot of surgical activity in rural Ethiopia: is enough being done?

BACKGROUND: Surgical conditions are responsible for a significant burden of the disease prevalence in sub-Saharan Africa. However, there is a paucity of data surrounding the amount and availability of surgical care. Few surveys exist that document current rates of surgical activity in the low-income setting, and most figures rely on the country estimates. We aim to document accurately the rates of surgery at the district level. METHODS: We performed a retrospective survey of surgical activity in 10 hospitals in the Southern Nation and Nationalities Peoples' Region of Ethiopia using a standardized data collection form. We also performed structured interviews with hospital directors. RESULTS: Surgical output varied across the hospitals from 56 to 421 operations per year per 100,000 catchment population. The most commonly performed operation was cesarean section (29% of major procedures). Emergency surgery accounted for 55% of operations, with the most frequent emergency operation being cesarean section. The overall cesarean section rate was alarmingly low at 0.6%. There are only 76 health workers that are providing a surgical service to this sample population of 12.9 million people. CONCLUSIONS: The rates of surgery found here were very low, consistent with the huge shortage of health workers providing a surgical service. The low cesarean section rate indicates that there is a large unmet surgical disease burden at the population level, and more comprehensive surveys are required to investigate this further. The most important steps to tackle the problem of deficiencies in global surgery are to increase access to surgical care and the surgical workforce capacity.

The effect of acidosis on the ECG of the rat heart.

We have investigated the effect of acidosis on the ECG in isolated rat heart to determine whether acidosis has marked effects on the ECG, and have used pharmacological agents to investigate possible mechanisms whereby acidosis alters the ECG. Acidosis produced a marked decrease in heart rate and an increase in P-R interval with little apparent effect on the duration of the QRS complex. The effects of acidosis did not appear to be due to acidosis-induced changes in transmitter release from severed autonomic nerve terminals within the heart. Experimental Physiology (2001) 86.1, 27-31.
