This article examines British Columbia (BC)'s Physician Information Technology Office's efforts to measure and improve the use of electronic medical records (EMRs) by select practices in BC with an assessment of their progress using a maturity model, and targeted support. The follow-up assessments showed substantial increases in the physicians' scores resulting from action plans that comprised a series of tailored support activities. Specifically, there was an increase from 21% to 83% of physicians who could demonstrate that they used their EMRs as the principal method of record-keeping.
