Texas hospitals using health information technologies had fewer complications, lower mortality rates and lower costs, a UT Southwestern Medical Center researcher has found.
The study, available Jan. 26 in The Archives of Internal Medicine , measured automation in urban hospitals using a Clinical Information Technology Assessment Tool. The tool, administered to physicians who provide inpatient care, assesses the degree to which clinical information processes in the hospital are computerized.
"Hospitals that achieved a highly usable, well-structured technology system that physicians wanted to use had extraordinary outcomes," said Dr. Ruben Amarasingham, assistant professor of internal medicine at UT Southwestern and the study's lead author. "If implementation is done well, health information technologies can be hugely beneficial for patients. To our knowledge this is the largest study of its kind examining hospital information system capabilities from the perspective of the physician."
Texas was selected as the study site because of its large and diverse patient population and its wide range of hospitals.
Three factors were measured for a hospital to receive a high score: The information process must be available as fully computerized; the physicians must know how to activate the computerized process; and they must choose the computerized process over other alternatives, such as paper-based documentation.
Dr. Amarasingham and his colleagues examined the association between the hospitals' automation and inpatient mortality, complications, costs and length of stay among patients with myocardial infarction, congestive heart failure, coronary artery bypass grafting or pneumonia.
