    Guidelines: Physicians' preference, improved knowledge, implementation, and improved patient outcomes

    Several concerns/comments came up while I was reading this interesting study. The association between outcomes of interest (preference and knowledge) and different interventions (two formats of guideline presentation) might not be as strong or might be even weaker for the following reasons. 1. Preference: Noticeably, there were some differences in preferred knowledge source between the two groups at baseline- 5% more participants in the standard format group preferred that from colleagues. This might reflect somewhat varied levels of acceptance for practice guidelines or other evidence sources of high quality and more reliable in the two groups. This would partially explain the difference in proportions of participants who preferred the formats they respectively saw in the interventions. 2. Knowledge: The authors did not test the level of medical knowledge or practice experience in the two groups at baseline. It is possible that participants in the multilayered format group had a better knowledge fund or more experienced in the issues addressed in the guideline before the interventions. Thus, they scored slightly better in the MCQs (not statistically significant in the study) than the standard format group. Additionally, the MCQs might not cover all the contents or information delivered through the interventions. Therefore, the small difference in MCQs performance may not accurately reflect the difference of knowledge levels in the two groups after the interventions.
