Simulation-based learning plays an important role in contemporary medical education, although there are problems providing tutors. Peer-assisted learning has begun being formally adopted in medical education. Although it is considered useful for simulation-based learning, its effectiveness remains unclear. This study was designed to compare the effect of simulation-based learning with that of traditional lectures conducted by postgraduate-year (PGY)-II residents on PGY-I residents.<br/>
METHODS:<br/>
This study was conducted at Okayama University Hospital over three years, for one week each year, before residents entered clinical practice. The study enrolled 76 PGY-I residents, who were randomized into two groups: simulation and lecture groups. PGY-II residents volunteered to conduct simulations and lectures. Knowledge evaluation was performed using pre- and post-tests, and self-evaluation of competence and behaviour-change and program evaluations were conducted using questionnaires.<br/>
RESULTS:<br/>
In both groups, knowledge test scores were found to improve significantly, and the score difference between pre- and post-tests in both the groups was not significant. Self-evaluation of competence and behaviour-change was found to be higher in the simulation group than the lecture group. The trainees in the simulation group valued the program and the PGY-II residents as teaching staff more than those in the lecture group.<br/>
CONCLUSIONS:<br/>
The combination of simulation-based learning and peer-assisted learning led by PGY-II residents is potentially more effective in improving the postgraduate education of PGY-I residents than the combination of lecture and peer-assisted learning.No potential conflict of interest relevant to this article was reported.岡山医学会Acta Medica Okayama0030-155812822016腸骨広範囲切除術後に発生した腹壁瘢痕ヘルニアに対しメッシュ修復術を行った一例117120ENKazunoriTsukudaMinimally Invasive Therapy Center, Okayama University HospitalHiroakiAsanoMinimally Invasive Therapy Center, Okayama University HospitalYasuhiroMandaiCenter of the Development and Health Care Education, Okayama UniversityToshiyoshiFujiwaraDepartment of Gastrointestinal Sugery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences The patient was a 46-year old Japanese female who had undergone wide excision of the iliac bone and hip transposition at our institute's orthopedics department 2 years earlier. She presented with a growing incisional hernia and was transferred to our gastroenterological surgery department for surgical treatment. We planned a mesh repair for the incisional hernia, which protruded over the right iliac bone. The dimensions of the abdominal defect were 15×9 cm, and we used prolene mesh to repair the defect. The mesh was fixed at the inner part of the iliac bone, folded back at the iliac horn and fixed to the abdominal oblique muscles. The postoperative course was smooth, and recurrence was not seen at 3.5 years after the operation. An incisional hernia as seen in this patient's case is very rare, but we found that the underlay technique and prolene mesh were very useful for the three-dimensional hernia repair.No potential conflict of interest relevant to this article was reported.岡山医学会Acta Medica Okayama0030-155812812016インストラクショナル・デザインを もとにした医療教育の実践4750ENYasuhiroMandaiNo potential conflict of interest relevant to this article was reported.
