Modeling economic aspects of hospital information systems to give decision support for strategic information management.

Information systems require strategic planning in order to adapt their functionality and quality to the needs of health care organizations. Next to effectivity, cost efficiency in supplying and operating information systems is a particular objective. Hospital information systems with their technical infrastructure, their application systems and the hereby supported business functions can be described with the help of the meta model 3LGM2 and the 3LGM2 tool. The meta model and the 3LGM2 tool are extended by a generic approach to show supply and operation cost for all components of the information system and for the cost calculation between these components. This leads to the fact that all executives in hospitals are enabled to get the cost transparent which were caused by the support of the functions by the information system. The effects of planned extensions and modification of the information system can be analyzed in term of cost. In a prototypical modelling, the information system of a hospital of regular standards has been evaluated in nearly all its components and cost. An evaluation could show that information managers and executives are now delivered relevant cost information for planning, operating and control of information systems.

Integrating images into a central medical information system.

Of the information items that must be easily available to the different actors involved in the care process, radiological images are not the least important. While until recently it was not feasible to include these into the medical information system, this situation has changed. Still, emphasis in PACS (Picture Archiving and Communication Systems) is primarily on the technological aspects. In this paper, in contrast, we stress the importance of integration of images into the overall workflow and into the overall medical record. We do so using illustrations from the PACS project of the University Hospitals Leuven. We briefly indicate that tight integration at the user interface level is needed, and that this requires more than standardized communication between subsystems.

Towards relevant medical information systems.

The successful development of computer information systems in medicine is fraught with problems. Structured methods of analysis and design are becoming increasingly popular and are seen as the means of overcoming many of the technical problems associated with these systems. Information systems, however, are notoriously complex and require socially oriented as well as technically oriented solutions. A fundamental problem, in which these two distinct perspectives are intertwined, is the effective communication of requirements between users and designers of medical information systems. In this paper, data modelling is proposed as a means of integrating these approaches by assisting in socio-technical design. One specific diagrammatic variant of this established technique is introduced by means of a case study in ambulatory care. The case study is also used to illustrate a unique participative approach intended to facilitate discussion of the user's requirements. This more active approach to modelling is discussed in relation to the softer perspective of problem setting rather than the traditional one of problem solving.

[Automated microbiological information system].

The microbiological information system ISM gives the possibility to collect data of patients and findings on punch strips, to transmit the findings to the senders and to store and evaluate the data according to medical points of view and for the purpose of performance statistics. The essential elements of the system are demonstrated and the basic principles of the data processing apparatus type R300 are described. Here the author particularly enters the calculator-internal testing processes for elimination of codation and punching errors. Finally the further development of the information system provided is briefly sketched. The advantages of the use of electronic data processing result from 1. the simplificstion and unification of the information relations, 2. the reduction of writing work, 3. the centralised transmission of findings, 4. the increased security of data and 5. the possibility of mathematico-statistical evaluations of the stored data material. According to its basic conception the information system ISM may be used universally and it is possible to enlarge it.

Meeting the challenges of information systems planning.

Strategic information systems planning (SISP) is the process of deciding the objectives of computing for an organization and then identifying the applications that the organization should computerize. SISP has become increasingly important as information systems have begun to play a more critical role in implementing business strategies. However, SISP is beset with problems that hinder organizations from determining their computing objectives and applications. This article identifies the impediments to SISP and offers some constructive actions for business planners to take to increase their chances of success. It also suggests that planners may face greater difficulties implementing their information systems plans than in initially creating them.

Evaluating a comprehensive outpatient clinical information system: a case study and model for system evaluation.

Decisions about information system implementation are often justified through a cost-benefit analysis. The ability to improve efficiency and outcomes while decreasing costs through information systems--by allowing for multiple and instant simultaneous access to information, through data monitoring and altering, through automation of protocols, and by collecting information for population-based health care as opposed to individual illness-care--are all potential benefits of a comprehensive clinical information system. Measuring the quantitative impact of these system improvements, however, is difficult. Doing a complete cost-benefit analysis of a comprehensive clinical information system is unrealistic due to the many assumptions necessary and the multiple confounding factors that are involved. In our Clinical Information Systems deployment in Kaiser Permanente, Northwest Region, we have elected not to do a detailed cost-benefit analysis. Instead, we have done an evaluation, based on success criteria, of a pilot implementation of a vendor-supplied system. This evaluation is based on clinician acceptance, system usage, technical factors, and quantitative effects on physician productivity. We also considered qualitative factors such as relationship with and responsiveness of the system vendor. We are moving ahead to regionalize this clinical information system based on such an evaluation of our pilot project. This paper outlines the approach that we have taken in evaluating our implementation of this system. It may provide some guidance for organizations on how to make a decision about whether or not to regionalize a clinical information system based on the evaluation of a pilot-site implementation.

Implementing an executive information system.

Too often information systems have not provided the information executives need, in the necessary time frame and at the level of usability that they require. Executive information systems, which are designed to quickly cull through critical information and present it in a highly usable format, are appropriately positioned to fill this growing need.

Implementation of a computerized patient advice system using the HELP clinical information system.

A COMputerized Patient Advice System (COMPAS) was designed to test the feasibility of using the HELP clinical information system to direct the respiratory therapy of intensive care (ICU) patients acutely ill with adult respiratory distress syndrome. A modified black-board control architecture allowed the application of knowledge in either a forward or a backward chaining mode. Expert clinicians recommended decision logic and actions for five different modes of ventilatory support. The clinical staff used COMPAS to manage the ICU ventilatory support of five patients for a total of 624 hr. During that time there were 407 decision-making opportunities. COMPAS automatically generated therapy suggestions 379 (93.1%) times and the clinical staff accepted COMPAS's recommendation in 320 (84.4%) of these cases. These results suggest that the ventilatory support of severely ill ICU patients can be managed by a clinical information system using a blackboard control architecture.

Buying information systems.

When purchasing information systems, the buyer or manager must be able to account for many types of details. Major considerations include a total awareness of costs relating to conversion, site preparation, equipment, software, maintenance, and supplies. The buyer's needs, as well as the system's capabilities, must be carefully weighed. In addition, a hidden element, the true cost of making the purchasing decision, is a vital consideration in the process of choosing the best available information system.

Improving the cost, quality, and access to healthcare in community hospitals through the use of reorganized integrated delivery systems and implementation of sophisticated clinical information systems: an organizational experience.

It is well recognized that health care is undergoing fundamental and necessary change. These changes rival, if not exceed, changes that have occurred in other industries. The factors underlying the changes are varied, but fundamentally, the economics of health care have altered. A new economic model is evolving that is disciplined by the marketplace and/or regulatory determination of "price" on a per capita basis. Success in this new model will require integrated delivery systems (IDS) serving local communities linked to purchasers through affiliations that span broader geographic areas. The demands of this model are placing unparalleled requirements for change on health care providers including the need to develop new forms of delivery systems and implement sophisticated new information systems that allow collection and detailed analysis of important clinical and financial data in an effort to achieve better value in health care. A case study of the Health and Hospital Services, Inc. (HHS) integrated delivery system and information system strategy will be discussed.

Development of a GIS-based spill management information system.

Spill Management Information System (SMIS) is a geographic information system (GIS)-based decision support system designed to effectively manage the risks associated with accidental or intentional releases of a hazardous material into an inland waterway. SMIS provides critical planning and impact information to emergency responders in anticipation of, or following such an incident. SMIS couples GIS and database management systems (DBMS) with the 2-D surface water model CE-QUAL-W2 Version 3.1 and the air contaminant model Computer-Aided Management of Emergency Operations (CAMEO) while retaining full GIS risk analysis and interpretive capabilities. Live 'real-time' data links are established within the spill management software to utilize current meteorological information and flowrates within the waterway. Capabilities include rapid modification of modeling conditions to allow for immediate scenario analysis and evaluation of 'what-if' scenarios. The functionality of the model is illustrated through a case study of the Cheatham Reach of the Cumberland River near Nashville, TN.
