A DATABASE DESIGNED FOR UTILIZATION MANAGEMENT IN DIAGNOSTIC IMAGING

: The methods and tools of health services research have been applied to a diverse number of health care areas. Surprisingly, they have been adopted only recently in diagnostic imaging, by a small number of professionals, in response to the severe fiscal constraints and widespread structural changes in the health industry, as well as to a growing concern that the value of social and individual investment in high-cost imaging services could not be validated objectively. As a result of the need for accountability for the use of scarce resources, regulators and payers of health services increasingly demand that a reasoned and objective evaluative process be adopted. To undertake a statistically driven evaluative approach that stands up to objective assessment of methodological rigour, an organized data-collection system is needed. Without this fundamental cornerstone, evaluators are left with little more than anecdotal evidence and professional and personal opinion to guide decision-making. It then becomes difficult to learn from both the successes and failures that are routinely experienced during times of rapid and fundamental change. This article describes the efforts made to integrate health services research in radiology into the routine daily activities and supporting systems of a large academic health system, the Hamilton Health Sciences Corporation and McMaster University Department of Radiology, in an attempt to move in the direction of evidence-based decision-making. The authors hope this will allow others to learn and improve on this work. Radiologists may then move the vast data systems and infrastructure associated with all imaging services to an evidence-based model for managing and guiding the vast resources entrusted to our collective stewardship.
