Evaluation of a computer-assisted instruction (CAI) module for a patient controlled analgesia Pump

This project consisted of evaluating a computer-assisted instruction (CAI) module for a patient controlled Analgesia (PCA) pump. Evaluations of the CAI included a pre and post written knowledge test to measure the subject's knowledge about the PCA pump before and after completing the CAI. User satisfaction of the CAI was measured using the Questionnaire for User Interaction Satisfaction (QUIS). Eight subject improved their post-test score over their pre-test score. Analysis using the Wilcoxon-Signed Ranks Test produced a maximum signed rank sum of 36, which indicates effectiveness with significance at the 0.005 level. The overall QUIS score was 6.53 out of a possible score of 9. A score of 6.53 indicates a moderate level of satisfaction. Observation while completing the CAI indicated satisfaction with the CAI. While there was satisfaction with the CAI, the nurses noted some problems with the ability to correct errors and with system speed. Overall, the nurses felt the CAI would be beneficial if the problems noted could be fixed.
