Electronic patient record systems and the general practitioner: an evaluation study.

We studied how well electronic patient record (EPR) systems meet the needs of general practitioners (GPs) and other health-care professionals for specific information. GPs in eight health centres in the South-Ostrobothnia region of Finland were invited to participate. They used three types of EPR system. They were asked to access EPRs to obtain 20 types of information for patients receiving anticoagulant treatment. In total 2,389 patient cases were studied. All of the information requested was available for 73% of the cases (range 55-93%). There was a significant difference between the type of EPR system and the percentage of patients for whom information was available through the EPR. However, further analysis showed that differences in performance between EPR systems probably reflected differences in the way EPRs were used by different organizations. Great care should be taken in attempts to rank EPR systems based on their performance.
