LABKA. A real-time computer system for the clinical laboratory.
This paper provides an introduction to the real-time clinical laboratory information system (LABKA), which is implemented on a Hewlett-Packard 1000 system. The system is optimized for fast data handling combined with easy control of on-line results, data flow, and linking of related information. The design of LABKA is based on the principle of having a short reporting time together with simplified working procedures. The system can be adjusted to small as well as very large laboratories. Data control is achieved by status information being returned to the operator in real-time, thus avoiding having to use matching lists. This information is presented immediately in response to the procedure which has caused the error. This method of early error detection simplifies working procedures, inhibits accumulation of errors, and increases the flexibility and speed of data reporting. As a result, the number of requested stat analyses has been reduced by 50 percent. Working lists are not generally used. Instead, requisition information is transferred on-line to the instruments on request. A fourth-generation program system for entry, calculation, and test of manually entered data, called RUCAT (1), has been developed. This system enables the user to define forms on vdu-terminals, specify calculations, and test all manually entered data. The LABKA system can also produce cumulative reporting as standard reporting, in real time, fast and in a very high print quality. The real-time demands have strongly influenced the design and layout of the lab files and system design.
