Trial Outcomes & Findings for Improving Diabetes Care:Effectiveness of Physician Profiling and Care Coordination by a Diabetes Resource Nurse (NCT NCT00258674)

NCT ID: NCT00258674

Last Updated: 2017-06-14

Results Overview

Each patient was assigned a "change score" of -1, 0, or 1. A positive value indicated a patient non-adherent to the guideline recommendation for HbA1c \<9 percent at baseline had achieved such a level at follow up. Patient-level change scores were then summed and averaged over each study arm.
