Abstract

A system is described for the maintenance of cumulative haematology records for selected patients using a laboratory minicomputer with limited storage capacity. Records are indexed by the patient's name and location since, as in the majority of hospital laboratories, there is no unique numbering scheme which covers all patients. The computer system imitates the procedures of manual filing, listing uncertain record matches for human decision. Applications include the production of a regularly updated printing of of cumulative files, the preparation of graphs from cumulative blood count records, and the provision of a summary and follow-up service for general practitioners.
