title: Rectal Carcinoma Model: A Novel Simulation in Pathology Training.
abstract: BACKGROUND
  Until now, the apprenticeship training model is used to train pathology residents. Pathology residents are trained using patient specimens that are received during the course of normal daily pathology service. However, this training method could result in inconsistency in knowledge and experience among trainees because of variation in specimens that are received for analysis. The use of simulated specimens in pathology residency training could help ensure that all pathology residents receive consistent knowledge and experience. The aim of this study was to develop prototype rectal carcinoma model to be used as a simulation tool and to evaluate its effectiveness in pathology training.
  
  
  METHODS
  Five units of a prototype rectal carcinoma model were produced in latex rubber. The model was used as a simulation tool for training in 12 pathology residents and 7 pathologist assistants. Pretesting and posttesting of each participant was conducted by multiple choice question test. A questionnaire was also given to study participants to elicit their views regarding the fidelity of the model and the model's efficacy and usefulness relative to the gross examination technique.
  
  
  RESULTS
  Among the 19 participants, the mean pretest score was 79.24% and the mean posttest score was 88.54% (P = 0.045). The fidelity of the model was rated as moderate to marked by all participants. Most participants (94.74%) rated the models efficacy and usefulness relative to the gross examination technique as being moderate to marked.
  
  
  CONCLUSIONS
  The rectal carcinoma model introduced in this study was found to be an effective simulation tool for pathology training. The model had good fidelity on appearance and good efficacy as well as usefulness relative to the gross examination technique.
