Data that makes a difference in quality improvements in primary health care: approaches through a pan-Canadian voluntary electronic medical record source.

Primary Health Care (PHC) is the most common health care experienced by Canadians and is an important source of chronic disease prevention and management; however, PHC providers say they have little information about their patient populations, especially groups of patients with multiple conditions. The Canadian Institute for Health Information in collaboration with 50 PHC providers examined the ability to extract and use a subset of PHC EMR data from four disparate environments in an agreed and privacy sensitive manner. Findings describing the feasibility of clinician engagement, EMR data extraction, EMR content standards and data utility gaps, information system requirements, and systemic enablers and barriers are described in this paper. Ability to collect and use discrete and standardized clinical and administrative information is fundamental to improving practice efficiency, optimal use of information, and patient quality of care. Improving quality of EMR data captured at the point of service will considerably enable our ability to measure and understand PHC across Canada; promote dialogue to identify priority information needs; and support health system information uses for clinical program and health system management, research, and population surveillance.
