XIII. Hospital Information Systems: F. Strategic Planning for Hospital Information Systems: A Method of Conducting Controlled Testing of Hospital Information System Components

摘要

One of the greatest areas of difficulty in the acquisition and installation of Hospital Information Systems is the system testing and validation. These systems are complex, consisting of a large number of program modules. These program modules tend to have a high degree of dependency upon one another and the system's data files.The real-time nature of Hospital Information Systems, and the types of applications supported by these systems, introduces new problems in testing and validation of the system's programs. New techniques are required to replace those used in testing batch oriented systems.Through the use of a controlled testing methodology, a Hospital Information System can be tested and validated with a limited risk factor of failure after the system is installed. The quality of testing is directly reflected in the reliability of the installed system and its acceptance in the hospital environment by the affected department's staff.
