Some tools for the diffusion of biomedical information using research networks.

Research and academic computer networks provide e-mail and other services to all members of participating institutions. Their usage by biomedical researchers and clinicians is still limited because of several reasons, including limited awareness of the available network resources. An increased use of these networks within the biomedical community would allow fast, effective communications and convenient remote access to information sources. As an example and pilot study, we prepared two network tools to make some information services maintained by our institution also accessible through e-mail. Both tools were implemented using PMDF e-mail software on a DEC MicroVAX connected to the Italian academic and research network (GARR), which is linked to the U.S. Internet. A network server takes care of automatic distribution of documents (files) reporting results of an oncology research/education project. An information server provides for semiautomated support of a consulting service on use of drugs. The feasibility of implementing these tools, based on existing software, further illustrates the potential usefulness of research computer networks for the dissemination of biomedical information.

Expediting prior approval and containing third-party costs for dental care.

Dental insurance carriers frequently require referral of radiographs for determination of prior approval. Radiographs are also often used for obtaining expert opinions before finalizing diagnoses and establishing treatment plans. Traditionally, such referrals have been carried out using the original or duplicate films transmitted through the postal system. Studies concerning alternative communication media for data transmission are presented, namely, the use of switched-digital telephone lines and of electronic mail networks.

Conducting regional health surveys using a computer-assisted telephone interviewing method.

After the creation of thirteen health regions within Queensland in 1991, the need arose for an information base at the regional level to assist regions with their role in planning, monitoring and evaluating health services. A series of regional health surveys was conducted in 1993 to provide this information, using a computer-assisted telephone interviewing method. Over 10 400 interviews were conducted throughout the state. This is the first time a computer-assisted method has been used on a large scale to collect health-related information in Australia. Interviews used list-directed or random-digit dialing, depending on the rate of unlisted numbers in a region. Response rates were not significantly different for the two methods, although the number of contactable numbers attempted and the noncontact rates were significantly higher for random-digit regions. The last-birthday method was used to select the adult for interview in each household. The method resulted in a bias toward female respondents.

Electronic communication between providers of primary and secondary care.

OBJECTIVE: To study the effects of the introduction of electronic data interchange between primary and secondary care providers on speed of communication, efficiency of data handling, and satisfaction of general practitioners with communication. DESIGN: Comparison of traditional paper based communication for laboratory reports and admission-discharge reports between hospital and general practitioners and electronic data interchange. SETTING: Twenty-seven general practitioners whose offices were equipped with a practice information system and two general hospitals. OUTCOME MEASURES: Paper based communication was evaluated by questionnaire responses from and interviews with care providers; electronic communication was evaluated by measuring time intervals between generation and delivery of messages and by assessing doctors' satisfaction with electronic data interchange by questionnaire. RESULTS: Via paper mail admission-discharge reports took a median of 2-4 days, and laboratory reports 2 days, to reach general practitioners. With electronic data interchange almost all admission-discharge reports were available to general practitioners within one hour of generation. When samples were analysed on the day of collection (as was the case for 174/542 samples in one hospital and 443/854 in the other) the laboratory reports were also available to the general practitioner the same day via electronic data interchange. Fifteen general practitioners (of the 24 who returned the questionnaire) reported that the use of electronic admission-discharge reports provided more accurate and complete information about the care delivered to their patients. Ten general practitioners reported that electronic laboratory reports lessened the work of processing the data. CONCLUSION: Electronic communication between primary and secondary care providers is a feasible option for improving communication.

CDC WONDER: a cooperative processing architecture for public health.

CDC WONDER is an information management architecture designed for public health. It provides access to information and communications without the user's needing to know the location of data or communication pathways and mechanisms. CDC WONDER users have access to extractions from some 40 databases; electronic mail (e-mail); and surveillance data processing. System components include the Remote Client, the Communications Server, the Queue Managers, and Data Servers and Process Servers. The Remote Client software resides in the user's machine; other components are at the Centers for Disease Control and Prevention (CDC). The Remote Client, the Communications Server, and the Applications Server provide access to the information and functions in the Data Servers and Process Servers. The system architecture is based on cooperative processing, and components are coupled via pure message passing, using several protocols. This architecture allows flexibility in the choice of hardware and software. One system limitation is that final results from some subsystems are obtained slowly. Although designed for public health, CDC WONDER could be useful for other disciplines that need flexible, integrated information exchange.

Managing the electronic NIH-guide for grants and contracts.

This article describes the implementation of a suite of computer programs to manage and provide access to a database containing the electronic documents that constitute the NIH-Guide that is distributed by the NIH on a weekly basis. The software consists of a management program that reads, processes, and stores the incoming documents and performs erratum updates on existing documents; an alerting program that sends selected information to users who have registered their information needs; a viewer that can be used on the local computer to read these documents; and a World-Wide-Web (WWW) server that can distribute the guide to computers that run WWW client software. The design of the documentation annotations, the management software, and the WWW server are expected to constitute valuable models for similar projects in the future.

Use of the equity implementation model to review clinical system implementation efforts: a case report.

This paper presents the equity implementation model (EIM) in the context of a case that describes the implementation of a medical scheduling system. The model is based on equity theory, a well-established theory in the social sciences that has been tested in hundreds of experimental and field studies. The predictions of equity theory have been supported in organizational, societal, family, and other social settings. Thus, the EIM helps provide a theory-based understanding for collecting and reviewing users' reactions to, and acceptance or rejection of, a new technology or system. The case study (implementation of a patient scheduling and appointment setting system in a large health maintenance organization) illustrates how the EIM can be used to examine users' reactions to the implementation of a new system.
