Part B–A modified KP50 questionnaire
Table 4 describes the results of a knowledge questionnaire on various subjects related to pain physiology, pain management, and side effects of drug therapy (see Appendix C). This part was based on selected questions from the KP50 questionnaire. A perfect score is 75. Prior to educational intervention, the average score for all physicians is 45.7/75 with a median of 46/75.
After the intervention, a significant improvement was observed as the mean score increased to 52.70/75 with a median of 55/75 (p.value = 0.012).
