The Use of Decision Analysis Tools for the Selection of Clinical Laboratory Tests: Developing Diagnostic and Forecasting Models Using Laboratory Evidence

Abstract

The number and complexity of available laboratory tests continues to increase at a rapid pace. Staying current with accepted standards for laboratory testing for diagnosis, monitoring and prognosis is extremely challenging, particularly for nonspecialists who see a diverse patient population. Decision support tools to aid physicians in appropriate test selection and interpretation are widely available and will become increasingly important. The most effective and practical decision support tools are developed or selected locally at the institutional level and embedded in the regular workflow of the physician. Many of these tools can be incorporated into the electronic medical record system where they can be easily accessed by any physician while caring for their patients. Careful attention to the “Ten Commandments for effective clinical decision support,” described by Bates et al., will enhance the chances for success in the design and implementation of new decision support tools.
