About Us

All about DMAR System

The DMAR was invented in 2005 by Drs. Oliver and Quinn in Toronto, Canada to overcome the limitations of traditional electronic medical records when their data is analyzed to measure performance. We have iteratively developed patented methods for measuring health care performance including:


Health care performance is often measured from existing electronic systems even if data quality is poor because it is all that is available. Other people think collecting high quality data at scale is not possible. We disagree. We believe if busy health care professionals are asked to spend their valuable time collecting data, it is our responsibility to ensure the data is accurate and it provides valuable information. Achieving these goals takes time and effort. However, we do make every effort to leverage existing electronic sources and we only collect data that has impact. We don’t collect data that is just “nice to have”.


Often data within electronic health records is incomplete or contradictory. In DMAR systems, we compare data from multiple sources until the patient’s true medical history is clear and complete. This process often identifies weaknesses or gaps in documentation which are corrected as we implement the system. The DMAR dataset can be thought of as a gold standard, abstracted version of the medical record which can be used for multiple benefits.


In order to compare apples to apples across institutions, we ensure all programs apply the same definitions and coding framework. We have developed detailed and accurate coding systems for for this purpose. It's akin to accounting where financial information is organized and standardized to produce a financial report. Programs using DMAR receive important insights because we truly deliver “apples to apples” comparisons.


DMAR data (excluding patient identifiers) is reviewed by our DMAR experts to ensure consistency in coding and that there is no missing information. Queries are communicated in real time to users who must correct them before data is approved. These methods are similar to clinical trials. Once data is approved it is segregated so it can be used for timely analysis.

Analysis & reporting

DMAR systems facilitate timely and accurate analysis because the data is cleaned up front when it is collected. The “return on investment” in data quality is now realized to improve patient care, increase revenue and reduce costs.
