Methods for Evaluating Costs of Automated Hospital Information Systems*

摘要

With sponsorship from the National Center for Health Services Research, Arthur D. Little, Inc. conducted a study to review methodologies for assessing the cost impacts of automated hospital information systems (AHIS). Research done in this area in the past has been assembled and reviewed. Approaches in these studies to the identification, prediction or measurement, and analytical treatment of specific cost impacts are compared and their adequacy and validity assessed. In this paper, two particularly troublesome methodological issues are discussed: predicting labor savings and valuing impacts of automated billing.
