BackgroundDesigning and delivering evidence-based medical practice for students requires careful consideration from medical science educators. Social Web (Web 2.0) applications are a part of today’s educational technology milieu; however, empirical research is lacking to support the impact of interactive Web 2.0 mobile applications on medical educational outcomes.ObjectivesThe aim of our study was to determine whether instructional videos provided by iPod regarding female and male urinary catheter insertion would increase students’ confidence levels and enhance skill competencies.MethodsWe conducted a prospective study with medical trainee intern (TI) participants: 10 control participants (no technological intervention) and 11 intervention participants (video iPods). Before taking part in a skills course, they completed a questionnaire regarding previous exposure to male and female urinary catheterization and their level of confidence in performing the skills. Directly following the questionnaire, medical faculty provided a 40-minute skills demonstration in the Advanced Clinical Skills Centre (ACSC) laboratory at the University of Auckland, New Zealand. All participants practiced the skills following the demonstrations and were immediately evaluated by the same faculty using an assessment rubric. Following the clinical skill evaluation, participants completed a postcourse questionnaire regarding skill confidence levels. At the end of the skills course, the intervention group were provided video iPods and viewed a male and a female urinary catheterization video during the next 3 consecutive months. The control group did not receive educational technology interventions during the 3-month period. At the end of 3 months, participants completed a follow-up questionnaire and a clinical assessment of urinary catheterization skills at the ACSC lab.ResultsThe results indicate a decline in skill competency over time among the control group for both male and female catheterizations, whereas the competency level was stable among the experimental group for both procedures. Interaction results for competency scores indicate a significant level by group and time (P = .03) and procedure and group (P = .02). The experimental group’s confidence level for performing the female catheterization procedure differed significantly over time (P < .001). Furthermore, confidence scores in performing female catheterizations increased for both groups over time. However, the confidence levels for both groups in performing the male catheterization decreased over time.ConclusionsVideo iPods offer a novel pedagogical approach to enhance medical students’ medical skill competencies and self-confidence levels. The outcomes illustrate a need for further investigation in order to generalize to the medical school population.

INTRODUCTION Intercostal chest drain (ICD) insertion is a commonly performed procedure in trauma and may be associated with significant morbidity. METHODS This was a retrospective review of ICD complications in a major trauma service in South Africa over a four-year period from January 2010 to December 2013. RESULTS A total of 1,050 ICDs were inserted in 1,006 patients, of which 91% were male. The median patient age was 24 years (interquartile range [IQR]: 20-29 years). There were 962 patients with unilateral ICDs and 44 with bilateral ICDs. Seventy-five per cent (758/1,006) sustained penetrating trauma and the remaining 25% (248/1006) sustained blunt trauma. Indications for ICD insertion were: haemopneumothorax (n=338), haemothorax (n=314), simple pneumothorax (n=265), tension pneumothorax (n=79) and open pneumothorax (n=54).Overall, 203 ICDs (19%) were associated with complications: 18% (36/203) were kinked, 18% (36/203) were inserted subcutaneously, 13% (27/203) were too shallow and in 7% (14/203) there was inadequate fixation resulting in dislodgement. Four patients (2%) sustained visceral injuries and two sustained vascular injuries. Forty-one per cent (83/203) were inserted outside the 'triangle of safety' but without visceral or vascular injuries. One patient had the ICD inserted on the wrong side. Junior doctors inserted 798 ICDs (76%) while senior doctors inserted 252 (24%). Junior doctors had a significantly higher complication rate (24%) compared with senior doctors (5%) (p<0.001). There was no mortality as a direct result of ICD insertion. CONCLUSIONS ICD insertion is associated with a high rate of complications. These complications are significantly higher when junior doctors perform the procedure. A multifaceted quality improvement programme is needed to improve the situation.
