A New Method of Assessing the Impact of Evidence-Based Medicine on Claim Outcomes.

Results: The newly developed methodology adequately assessed the relationship between claim outcomes (duration and medical incurred) and adherence to EBM guidelines, controlling for medical complexity, distinct number of International Classification of Diseases (ICD)-9 codes, and other confounding factors.
