A computer system for haematology: experience in the use of the Trent-Phoenix system employing two central processing units and seven analysers--three remote.

We describe a modified Phoenix data processing system which has been introduced over a three year period into the Leicestershire Haematology and Blood Transfusion Services. The system is unique, employing two central processing units, which serve six Coulter S Plus IVD Counters and a Coulter S880, three of the analysers being located in satellite haematology laboratories. Details are provided of the system design and experience with the data processing activities within haematology. The blood transfusion laboratories utilize the same computer and this will be the subject of a later report.

Transferability of a computer system for medical history taking and decision support in dyspepsia. A comparison of indicants for peptic ulcer disease.

The transferability of a British data base for differential diagnosis of dyspepsia using data obtained by computer interrogation was tested in 467 Swedish patients. The diagnostic value for peptic ulcer disease of symptoms such as frequent night pain relieved by food or antacids, smoking, family history of ulcer, food relief pain, male sex, and episodic pain was shown to be reproducible. However, for a number of symptoms their value for the diagnosis of peptic ulcer disease could not be reproduced in Swedish patients. The combined value of indicants was tested using a computer based algorithm for calculating diagnostic probabilities. The performance of this algorithm was poor when British data were applied to Swedish patients but reclassification of the Swedish patients on their own data base showed promising results. Crean and colleagues in Glasgow have developed a computer system for automated interrogation of patients with dyspepsia. The system utilises a large number of questions to obtain information regarding a maximum of 160 diagnostic indicants. The symptoms elicited from a patient can be compared with those of a large number of previously examined patients and the probabilities of ten different diagnoses can be calculated. The calculation of diagnostic probabilities is based on scores reflecting the diagnostic value of different symptoms in different diseases. After careful translation of questions the system has been transferred for use in Sweden. The present report is based on data from patients seen during the first two years with the system at a Swedish hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

A computer system for a blood transfusion laboratory.

A modified Phoenix data processing system has been introduced into the haematology laboratories in the Leicestershire District Health Authority. In the three blood transfusion laboratories the computer system has been fully operational for a year and has been found to aid the management of data within the department as well as improving the quality of the service.

[Effect of papaverine hydrochloride on brain circulation. Studies using a scintillation camera computer system].

The effect of papaverihnydrochlorid (Panergon-R) on the cerebral circulation time was studied in 20 sclerotic patients by means of radionuclide circulography as established by a scintillation camera-computer system. After a 28-days period of treatment a mean effective change of circulation time of minus 10.6 +/- 4.8 percent was to be observed. This change was statistically significant.

Implementing RECONSIDER, a diagnostic prompting computer system, at the Georgetown University Medical Center.

RECONSIDER, a computer program for diagnostic prompting developed at the University of California, San Francisco, has been implemented at the Georgetown University Medical Center as part of the Integrated Academic Information Management System Model Development grant project supported by the National Library of Medicine. The system is available for student use in the Biomedical Information Resources Center of the Dahlgren Memorial Library. Instruction on use of the computer system is provided by the library and instruction on medical use of the knowledge base is directed by the faculty. The implementation, capabilities, enhancements such as the addition of Current Medical Information and Terminology (5th ed.), and evaluation of the system are reported.

The use of gas chromatographic-mass spectrometric-computer systems in pharmacokinetic studies.

Pharmacokinetic studies involving plasma, urine, breast milk, saliva and liver homogenates have been carried out by selective ion detection with a gas chromatographic-mass spectrometric-computer system operated in the chemical ionization mode. Stable isotope labeled drugs were used as internal standards for quantification. The half-lives, the concentration at zero time, the slope (regression coefficient), the maximum velocity of the reaction and the apparent Michaelis constant of the reaction were determined by regression analysis, and also by graphic means.

Cost-benefit of laboratory computer systems.

The benefits and costs of a computer laboratory information system have been evaluated in three military hospitals, using a pre- and postimplementation comparison of time spent by laboratory and medical staff on information-handling activities, turnaround time for laboratory results, and staff perceptions of performance. The evaluation indicates that the laboratory information system is very cost-effective. A major benefit is the reduction in nursing staff time required to obtain laboratory test status and results.

The impact of computer systems in a medical environment.

The acceptance and proliferation of computer technology in health care has not been as rapid as many expected. Research in this area suggests that several factors are related to computer acceptance including social network processes, attitudes toward computers, and personality characteristics. Potential implications for the field of magnetic resonance imaging are discussed.

Using bar-code technology to capture clinical intervention data in a hospital with a stand-alone pharmacy computer system.

The use of bar-code technology to capture data on pharmacists' clinical interventions is described. At a hospital in Northern Ireland, patient-specific information could not be accessed through the pharmacy computer system. A system comprising six hand-held bar-code readers and software for downloading data was purchased. The pharmacy staff selected a range of fields for recording a wide array of data on clinical interventions, including the outcomes. Patient details that could not easily be bar-coded had to be recorded manually. The process was evaluated over three four-week cycles, with the data fields being revised after each cycle and the interventions being judged for their clinical appropriateness and their conformance to inhouse standards. After the third cycle, the need for manual recording of information was eliminated. A total of 857 interventions were made during the three cycles. Performance met or exceeded the standard for 7 (50%) of 14 indicators for the first cycle, 8 (53%) of 15 for the second cycle, and 13 (81%) of 16 for the final cycle. For all three cycles, the majority of the interventions were important and resulted in an improvement in the standard of care. A bar-code-driven data collection system successfully replaced a manual system for documenting pharmacists' clinical interventions.
