The Indiana network for patient care: an integrated clinical information system informed by over thirty years of experience.

Presented in this article is the Indiana Network for Patient Care, an integrated citywide medical record system that promotes health quality by enabling efficient access to clinical information. It begins with a description of the system's infrastructure, which includes an explanation of how the system accomplishes data integration. This is followed by a series of descriptions and rationales behind the many clinical applications that interface these data. In doing so, some of the factors that we feel contribute to the success of the system are illustrated.

Interfacing aspects between the picture archiving communications systems, radiology information systems, and hospital information systems.

Information relevant to radiological applications is commonly managed by several autonomous medical information systems including hospital information systems (HIS), radiological information systems (RIS), and picture archiving and communications systems (PACS). In this report, we explain the need to coordinate these systems and to provide some framework in which they can exchange information. In the first half of this report, we describe the integration of a PACS system into a hospital operation. Next, we present the interfacing methods between the HIS and the RIS, and between the RIS and the PACS. Two methods are further detailed for the communication between the RIS and the PACS (1) the triggered database to database transfer, and (2) the query protocol. The implementation of the first method successfully allows RIS reports, procedure and patient demographic information to be displayed at the request of the user along with the associated images at a PACS workstation. The query protocol allows a PACS to dynamically query RIS information. It will be eventually integrated into the design of a scientific multimedia distributed medical database system built on top of the HIS, the RIS, and the PACS.

Architectural design and tools to support the transparent access to hospital information systems, radiology information systems, and picture archiving and communication systems.

The fragmentation of the electronic patient record among hospital information systems (HIS), radiology information systems (RIS), and picture archiving and communication systems (PACS) makes the viewing of the complete medical patient record inconvenient. The purpose of this report is to describe the system architecture, development tools, and implementation issues related to providing transparent access to HIS, RIS, and PACS information. A client-mediator-server architecture was implemented to facilitate the gathering and visualization of electronic medical records from these independent heterogeneous information systems. The architecture features intelligent data access agents, run-time determination of data access strategies, and an active patient cache. The development and management of the agents were facilitated by data integration CASE (computer-assisted software engineering) tools. HIS, RIS, and PACS data access and translation agents were successfully developed. All pathology, radiology, medical, laboratory, admissions, and radiology reports for a patient are available for review from a single integrated workstation interface. A data caching system provides fast access to active patient data. New network architectures are evolving that support the integration of heterogeneous software subsystems. Commercial tools are available to assist in the integration procedure.

Harmonizing health information systems with information systems in other social and economic sectors.

Efforts to strengthen health information systems in low- and middle-income countries should include forging links with systems in other social and economic sectors. Governments are seeking comprehensive socioeconomic data on the basis of which to implement strategies for poverty reduction and to monitor achievement of the Millennium Development Goals. The health sector is looking to take action on the social factors that determine health outcomes. But there are duplications and inconsistencies between sectors in the collection, reporting, storage and analysis of socioeconomic data. National offices of statistics give higher priority to collection and analysis of economic than to social statistics. The Report of the Commission for Africa has estimated that an additional US$ 60 million a year is needed to improve systems to collect and analyse statistics in Africa. Some donors recognize that such systems have been weakened by numerous international demands for indicators, and have pledged support for national initiatives to strengthen statistical systems, as well as sectoral information systems such as those in health and education. Many governments are working to coordinate information systems to monitor and evaluate poverty reduction strategies. There is therefore an opportunity for the health sector to collaborate with other sectors to lever international resources to rationalize definition and measurement of indicators common to several sectors; streamline the content, frequency and timing of household surveys; and harmonize national and subnational databases that store socioeconomic data. Without long-term commitment to improve training and build career structures for statisticians and information technicians working in the health and other sectors, improvements in information and statistical systems cannot be sustained.

Putting a new SPIN (Sentara Physician Information System) on information systems. When was the last time you invested in your system's future?

Once you have a vision and strategy for the future, an information system will probably be your biggest and most important investment. Information systems that can track clinical data are critical to providing employers with the data they're demanding and doctors with the data they need. See how and why Sentara Health System developed the Sentara Physician Information System (SPIN).

A literature review on communication between picture archiving and communication systems and radiology information systems and/or hospital information systems.

The purpose of this literature review is to present the concepts surrounding the issue of communication between imaging systems and information systems in radiology and the literature about them. Picture archiving and communication systems (PACS) were developed to combine viewing of modality images, archiving, and distribution of images. When PACS is integrated/interfaced with radiology information systems (RIS) or hospital information systems (HIS), it can merge patient demographics, medical records, and images. To address several issues surrounding communication between PACS and HIS/RIS and to make interface development easier and faster, various organizations have developed standards for the formatting and transfer of clinical data. Additional work continues to better handle these issues. Communication protocol Health Level 7 (HL7) is a standard application protocol used for electronic text data exchange in health care by most HIS/RIS. The imaging communication protocol for PACS is the Digital Imaging and Communications in Medicine (DICOM) standard specification protocol that describes the means of formatting and exchanging images and associated information.

A three-level graph-based model for the management of hospital information systems.

Information processing in hospitals, especially in university hospitals, is currently faced with two major issues: low-cost hardware and progress in networking technology leads to a further decentralization of computing capacity, due to the increasing need for information processing in hospitals and due to economic restrictions, it is necessary to use commercial software products. This leads to heterogeneous hospital information systems using a variety of software and hardware products, and to a stronger demand for integrating these products and, in general, for a dedicated methodology for the management of hospital information systems to support patient care and medical research. We present a three-level graph-based model (3LGM) to support the systematic management of hospital information systems. 3LGM can serve as a basis for assessing the quality of information processing in hospitals. 3LGM distinguishes between a procedural level for describing the information procedures (and their information interchange) of a hospital information system and thus its functionality, a logical too level, focusing on application systems and communication links, and a physical tool level with physical subsystems (e.g., computer systems) and data transmission. The examples that are presented have been taken from the Heidelberg University Hospital Information System.

IHE: integrating the healthcare enterprise, towards complete integration of healthcare information systems.

Information systems of a modern hospital govern extremely important functions as patient management, control of work flows, administration etc. However a great variety of recommended standards are used while in most cases no effective coordination and intercommunication is possible. Some years ago to simplify and resolve this problem IHE was created; it is a technical framework which identifies a number of components of the healthcare enterprise (the "actors") whose interactions are defined in terms of "transactions", that should be implemented according to HL7 and DICOM standards. Attempting an in-depth understanding of IHE structure and its principles of function, those transactions that can occur among the various actors, which of these are supported and which require specific actors, are analyzed. IHE is continuously evolving, therefore open to the factual contribution of all health professionals who can point out the main instances that emerge daily from their activity in the field. While its origin was specific for the field of radiology, the true soul and driving force of the project lay on the type of approach used: to get together medical specialists and information technology professionals in order to identify and solve the difficulties which hindered an effective and functional integration of healthcare information systems.

[National public health information system].

Information production and its communication being a key public health activity, developing modern information systems is a precondition for its fulfilling these assignments. A national public health information system (NPHIS) is a set of human resources combined with computing and communication technologies. It enables data linkage and data coverage as well as undertaking information production and dissemination in an effective, standardized and safe way. The Croatian Institute of Public Health LAN/WAN modules are under development. Health Safety System, Health Workers Registry, and Digital Library are among the Institute's developmental priorities. Communication between NPHIS participants would unfold over the Internet by using every relevant data protection method. Web technology-based applications would be run on special servers. Between individual applications, use would be made of the transaction module of communication through an exchange of the HL7 standard-based xml messages. In the conditions of transition, the health system must make an optimal use of the resources, which is not feasible without applying modern information and communication technologies.

Managing the hospital's portfolio of information systems.

Information systems are becoming of such strategic importance that planning for them must not be left to weak selection processes that executives are tempted to avoid diplomatically because of the difficulty and the internal friction that determined management might cause. Presented here is a methodology for planning the evolution of information systems.

[Founding and development of the Croatian Health Information System].

Information systems, either computer or paper based, are the key to business effectiveness and efficiency of healthcare organizations. The rationale of starting a large healthcare informatics project by the Ministry of Health and Welfare may be argued by two needs: (1) the need of medical data transformation into the information required for public health policy decision-making; and (2) measures in the field of health and pharmacoeconomics, i.e. systematic surveillance of healthcare costs that define the prospects for savings without lowering the level of service (estimated at 20%-30% of potential savings), along with the need of transparency and adoption of European Union directives and standards. Implementation of the proposed system results in two groups of fundamental functions: (1) the creation of a central public health information system which facilitates real-time tracking of primary healthcare cost generators, which in turn are used for creating health economics policy, and (2) to automatize the process of generating a consolidated national health budget including the Croatian Institute of Health Insurance and hospitals as well as consolidated financial reports for all those involved in the healthcare system. The model of the National Health Information System of the Republic of Croatia is described.

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.

From nursing information systems to patient information systems.

Clinical information systems, developed for specific disciplines, reinforce the fragmentation of patient care and fail to support integrated, patient centered approaches. Fundamental restructuring of systems development is required to prepare the health care system and the practice of nursing for the future.

From hospital information systems to health information systems. Problems, challenges, perspectives.

OBJECTIVES: Hospital information systems are evolving towards health information systems. This article aims at identifying both proven benefits and critical issues, and at discussing problems and possible solutions. METHODS: Reports on HIS successes and failures were analyzed, and core challenges were identified. These challenges are discussed against state of the art solutions. RESULTS: In spite of demonstrated benefits, there are more severe problems than reports on successes suggest. Among today's core problems are integration, human-computer interaction, socio-technical issues, and support of processes. CONCLUSIONS: Significant efforts of all parties involved in the health care process are needed to improve, implement, and evaluate the concepts described.

Time and flow study results before and after installation of a hospital information system and radiology information system and before clinical use of a picture archiving and communication system.

The effectiveness of a hospital information system (HIS) and a radiological information system (RIS) was evaluated to optimize preparation for the planned full clinical operation of a picture archiving and communication system (PACS), which is now linked experimentally to the HIS and the RIS. One thousand IC (integrated circuit) cards were used for time studies and flow studies in the hospital. Measurements were performed on image examination order entry, image examination, reporting, and image delivery times. Even though after the HIS and the RIS operation only a small amount of time savings were realized in each time fraction component, such as in the patient movement time, examination time, and film delivery time, the total turn-around time was shortened markedly, by more than 23 hours on average. It was verified that the HIS and the RIS was beneficial in the outpatient clinics of the orthopedic department. Our method of measurement employing IC cards before and after HIS and RIS operations can be applied in other hospitals.

Measuring and improving quality using information systems.

Information systems (IS) are increasingly important for measuring and improving quality. In this paper, we describe our integrated delivery system's plan for and experiences with measuring and improving quality using IS. Our approach is that for quality measurement to be practical, it must be integrated with the routine provision of care, and whenever possible should be done using IS. Thus, at one hospital, we now perform almost all quality measurement using IS. However, IS are not only useful for measuring care, but represent powerful tools for improving care using decision support. Specific areas in which IS has already been particularly effective include reducing the unnecessary use of laboratory testing, reporting important abnormalities to key providers rapidly, adverse drug event detection and prevention, initiatives to reduce the costs of drugs, and making critical pathways available to providers. The next wave of effort will be to promote widespread use of computerized guidelines, which is likely to prove more challenging. However, the advent of managed care in the U.S. has produced strong incentives to provide high quality care at low cost, and our perspective is that only with better IS than exist today will this be possible on a widespread basis. Such systems make feasible implementation of care improvement and cost reduction initiatives on a scale which could not previously be considered.
