© Copyright 2004 - 2009 Irish Medical Journal. Electronic health records (EHR) support clinical management, administration, quality assurance, research, and service planning. The aim of this study was to evaluate a clinical data management programme to improve consistency, completeness and accuracy of EHR information in a large primary care centre with 10 General Practitioners (GPs). A Clinical Data Manager was appointed to implement a Data Management Strategy which involved coding consultations using ICPC-2 coding, tailored support and ongoing individualised feedback to clinicians. Over an eighteen month period there were improvements in engagement with and level of coding. Prior to implementation (August 2011) 4 of the 10 GPs engaged in regular coding and 69% of their consultation notes were coded. After 12 months, all 10 GPs and 6 nurses were ICPC-2 coding their consultations and monthly coding levels had increased to 98%. This structured Data Management Strategy provides a feasible sustainable way to improve information management in primary care.
