A taxonomy: hospital information systems evaluation methodologies.

During the past decade, computers and information systems and their resultant products have pervaded hospitals. Not only have the number of and investments in computers and their associated systems increased, but the types of hospital systems and affected functions have also multiplied. Unfortunately, methodologies to measure impacts of these systems have not evolved at the same pace. There have been few developments of new techniques. Existing techniques have not been adapted for use in hospitals. As a result, evaluations are not performed or are based upon generalizations, often with users minimally involved, if at all. Most techniques emphasize the cost-benefit approach, but this should not be the only tool used. This paper presents a taxonomy of methodologies for the evaluation of hospital information systems. The analyses of methodologies and systems are accomplished from user's perspectives. Effectiveness of system products is emphasized. Users are provided with an additional tool to plan, organize, control, and direct the information resources and achieve the hospital's goals and objectives.
