This report summarizes the third phase of the Telecommunications Information Network (TIN), which provides a telecommunications link between four remote southwest Ohio hospitals and the University of Cincinnati Medical Center, thereby reducing the isolation of healthcare providers at the remote hospitals. A description of the system explains the service, in which (1) requests for information from the site hospitals are telephoned to the Medical Center's Health Sciences Library or Drug and Poison Information Center; (2) staff professionals from these areas research each question using available resources; and (3) responses are transmitted orally, via telephone, and/or visually, via slow-scan television. The start-up, trial-operations, demonstration phases, and the projected operational phase are then described; project benefits are assessed; and the barriers to implementation and utilization are analyzed. Plans for institutionalization and barriers to full implementation are also discussed. The final section focuses on costing and financial information. References are listed, and appendices include a summary of the evolution of the TIN slow-scan system, several issues of a project newsletter, a script for a telecommunications slide-tape presentation, TIN miniposters, and a list of project-related presentations and publications.
