Beyond cost benefit: an assessment approach for the '90s.

A new evaluation approach is needed to evaluate clinical and management applications of H.I.S.-- where the major benefits may not be related to labor savings. New evaluation approaches also need to reflect a "bottom line" business orientation. We will describe an evaluation approach which is based on TQM concepts and meets both these criteria and incorporates benefits realization into the evaluation process.

Maximizing the benefits of health care information systems.

Information systems can improve cost control, increase the timeliness and accuracy of patient care and administration information, increase service capacity, reduce personnel costs and inventory levels, and improve the quality of patient care. However, experience shows that most of these benefits will not occur automatically following system implementation. Operational problems may exist that diminish information timeliness, accessibility, and accuracy; policies and procedures may not have been sufficiently tailored to reflect the realities and intents of the systems; and personnel tasks may not have been adequately restructured. In order to realize the full potential of information systems, health care organizations must plan for and implement strategies that are designed to maximize such benefits. This paper describes a method for developing benefits maximization strategies. The processes used to define strategies and their outcomes are presented.

Use of computerized information systems in U.S. health maintenance organizations and hospitals.

A comparison was made between the use of data processing in hospitals and Health Maintenance Organizations (HMOs). Findings indicate that the HMO and hospital data processing markets are currently quite distinct. As expected, the functions automated reflect the uses of the different care delivery systems. The hardware and software vendors to these markets are also different. A high percentage (50%) of HMOs are using software they developed in-house. In this respect, current HMO data processing is similar to the hospitals of a decade ago. The hospital market (for hardware and total systems) is highly concentrated. A few firms have a combined market share of over 50% and there are a large number of firms with very small shares. In the HMO market, there is a high concentration ratio for hardware but not for software or systems. HMOs and hospitals are almost uniformly satisfied with their hardware. Satisfaction with most applications is between 80 and 90% but there is a need, at least within HMOs, for improvements in support of the software supplied.

Planning for purchase and implementation of an automated hospital information system: a nursing perspective.

Planning for purchase, implementation, and use of an automated hospital information system is critical to its success. The planning process involves assessing needs, evaluating alternatives, selecting a system, and implementation support. Although an evaluation of costs and benefits of alternative systems is useful in planning for and selecting a system, the assessment can be very complex, and the assumptions used in the analysis are critical. Most benefits of automated systems are the result of improved timeliness, accuracy, and access to information, and these are difficult to value in dollars.
