[Real time processing of data from a clinical biochemistry laboratory by means of a computer system].

Our experience on the use, for several years, of an off line data processing system, has permitted the development of a more advanced system. The basis of the new system is implantation in the laboratory of a minicomputer, linked secondarily to a large computer. The introduction of viewing apparatus favours the development of conversational procedures essential for this application. The organisation of work stands, which varies with the type of blood investigation carried out, whether automatic, semi-automatic or manual, and depends on the use of specialised terminal, e.g. key-board, screen or printing machine, was particularly studied. Simpler procedures were also fully studied, for a routine laboratory must continue to function if the computer breaks down.

DERMIS: a computer system for assisting primary-care physicians with dermatological diagnosis.

DERMIS is a computerized skin disease diagnostic prompting system which has been derived from the prospective study of 5203 cases. It has been designed for use by non-dermatologists such as general practitioners. The program produces a list of reasonable diagnoses based on probabilities calculated using Bayes' theorem. Out of 221 precise diagnoses made by the dermatologist in the clinic, 42 groupings were created to encompass the most common or important diseases encountered in general practice. Four 'remainder' or 'send to specialist' groups were included for the 13% of uncommon conditions. The program, when tested by 'one out' analysis on the original cases, placed the correct diagnosis first on 76% of occasions, and within the first three on 95% of occasions. In 76 of 125 cases randomly selected from the data base, a request for diagnostic assistance had been made by the referring general practitioner. It has been estimated that in 54 of these 76 cases the DERMIS system could have provided differential advice with the correct diagnosis appearing at the top of the list. The system has been written in MUMPS and runs on an IBM-compatible desk-top computer. The software allows real time data entry. Arrangements are in hand for performing clinical trials of the system in general practice. If current performance is maintained, and the response to the system's output is favourable, then DERMIS might well enhance performance in medical decision making for the benefit of patients, medical services and budget holders.

The use of a micro-computer system in a lung function testing laboratory.

This report describes the use of a relatively inexpensive micro-computer, floppy disk drive and printer, now costing about 2000 pounds, in a routine lung function testing laboratory in a district general hospital. The computer calculates and types the results of lung function tests and calculates normal values and percentages. In addition it automatically generates a typed commentary on the results, files the current results on the disk and searches and tabulates previous results. The computer can produce lists of patients with particular characteristics and can also be used for other purposes.

NCTR computer systems designed for toxicologic experimentation. V. Post-experiment information system.

The Post-Experiment Information System (PEIS) is an automated data collection and reporting system composed of three specialized subsystems: Pathology, Chemistry and Microbiology. These subsystems function either independently or collectively to construct and maintain a comprehensive data base of all experimental values derived from, or associated with, an animal carcass. All data are retrievable by the unique Carcass Identification (CID) number assigned at death, which is the correlative of the Unique Identification Number (UIN) assigned to the animal at birth and used throughout its lifespan. Elements processed under the PEIS include gross and microscopic pathological observations, organ weights, hematologic data, chemical data, and microbiological analyses. The ability of the system to integrate the post-experiment data with the information collected on an animal from birth (BIS) and during the experiment (EIS) provides a complete animal history to the Principal Investigator or other requestor.
