PS1-52: Charting the Course: Adjudicating Fractures in Network Enrollees Using the Electronic Medical Record

Background/Aims In an era of increasing openness in health plans, use of electronic medical records (EMR) for detailed chart abstraction for all enrollees poses challenges. At Group Health Cooperative (GH), EMR data are most complete for enrollees in the Group Practice Division (GPD). However, all GH enrollees (from both the GPD and the Contracted Network Division (CND) have EMRs. CND providers do not have access to patients’ GH EMR. Information for CND enrollees is only entered when the patient or provider interacts with the GPD, such as a patient receiving GPD specialty care while receiving CND primary care. In the interest of achieving a larger sample size for an ongoing GH-based case-control study (FOCUS), we evaluated the feasibility of including CND enrollees by determining the proportion with sufficient EMR information for fracture adjudication.
