CLINT, which stands for Clinical Informatics NeTwork, is one of the clinical informatics initiatives in development at McMaster University's Health Information Research Unit. CLINT is a microcomputer-based system of over 60 workstations providing 24 hour availability of a set of clinical information resources to clinicians throughout our teaching hospital. CLINT encompasses three domains: (1) a user adaptable clinician-computer interface, (2) unique evidence-based health care content, and (3) automated data collection and viewing tools. An objective of the CLINT project is to determine CLINT's impact on the practice of health care. Early analysis of our data has revealed that over the past year, there has been widespread use of CLINT by clinicians from all clinical domains. Our next task is to evaluate CLINT's usefulness.
