Abstract

Introduction. Standard procedural skills training methods include tutorial, workshop, and feedback. Written manuals might add value to those standard methods; nevertheless, depends on how well they are composed. This research is aimed to evaluate the efficiency of well-written manuals of hand knotting skills in order to improve students’ procedural skills learning and competency. Methods. This research was conducted through preliminary study to identify the assessor reliability and main study to evaluate the students’ scores for reef and surgeon’s knots using an objective structured assessment of technical skills (OSATS). Subjects’ preparedness and perception of the quality of the manuals were evaluated through survey. Students were randomly divided into two groups. The treatment group received written manuals a day before the workshop. Both groups experienced same five steps procedural skills teaching methods. The results were analyzed by SPSS 17.0 through Pearson Chi-square test and independent t-test. Results. Preliminary study showed that the assessors had no difference in evaluating students’ skills. Main study included 31 subjects in treatment group and 34 subjects in control group. The OSATS scores were statistically significant different between the groups. Students in treatment group had higher mean scores (43.42±7.98) than those in control group (27.21±5.64); p Conclusion. Well-written manuals of hand knotting skills given prior to skills training improve student’s skills acquisition in addition to the standard teaching methods.

Abstract

Introduction. Postmortem changes in pigskin made it difficult to be manipulated as a model for advanced technique in surgery training. The use of bromelain enzyme on these pigskins could be an alternative way to obtain the ideal surgery training model. Method. Thirty-five pigskin-blocks (10×15cm) was divided evenly into seven groups consisted of six groups of different bromelain enzyme treatment (4g/20min, 4g/40min, 8g/20min, 8g/40min, 12g/20min, 12g/40min) and one group of control. Then five chief-plastic-surgery-residents blindly assessed and scored each pigskin and compared its likeliness to the back of human skin. The scores were then analyzed with an interrater reliability test using SPSS 16.0. Results. All five assessors unanimously chose the 8g/40min group as the most likeliness to the back of human skin. The highest score was obtained for piercing the needle into the pigskin (8.4 ± 0.54). Conclusion: The appliance of 8 grams bromelain enzyme in 10×15cm pigskin blocks for 40 minutes was proven to be an ideal surgery training model comparing the back of human skin, especially for tangential excision.
