Of 162.338 patients who between 1969 and 1978 received treatment at the Clinic of Stomatology, University of Halle-an-der-Saale, 9.069 (or 5.6 percent) were treated on an outpatient basis after having been diagnosed as having actinomycosis, osteomyelitis, lymphadenitis, difficult dentition, and nonspecific pyogenic soft-part infections (abscesses or infiltrates). A retrospective analysis by electronic data processing of case histories provided valuable information about morbidity, disposition, cause, localization, and the tendency for dental surgeons to refer certain cases to specialty clinics. There are pathognomonic differences in indexical systems for the different clinical pictures. Cases of osteomyelitis and soft-part infection with suspected actinomycosis were found to increase in correlation with the proportion of antimicrobially pretreated patients. About 60 percent of all patients receiving treatment at this Clinic were not referred thereto by dentists. Of the documents presented by patients referred to the Clinic of Stomatology by other dental surgeons, some 42.5 percent were filled out incompletely.
By the programme for detection of patients suffering from hypertension as appendage to the electronic data processing project "early detection of carcinoma of cervix uteri" in 54,020 examinations 10,469 women with hypertension were discovered and sent to competent specialists for continued observation and treatment. The portion of unknown hypertensions was 58.3%. In the examined female population of Karl-Marx-Stadt aged 20 to 65 years the prevalence of hypertension was 19.4% and corresponded to the results of national and international studies. - 16,714 women in the mainly fertile age were on hormonal contraceptives. The blood pressure of these women and of a comparable group without hormonal treatment was examined, the results were discussed. The histories did not allow to make conclusions for a certain disposition caused by the diagnosed hypertension. Moreover, our dates could not answer, if and which ranges the blood pressure (systolic and/or diastolic) increased in particular case.
In the course of the past 20 years, an astonishingly rapid development of modern programmable computers has taken place. Electronic data processing (EDP) has therefore become very cheap. EDP may be used in all types of research; however, this paper deals specifically with applications in preventive cariology and periodontology. The use of punch cards and magnetic tape for storing of dental data is discussed. The principle of error testing of dental caries data is exemplified. A simple program which performs DMF counts is presented and explained. Some principles for longitudinal caries studies are elucidated. The use of large computing centres for processing extramural clinical studies is discussed. Some examples of progress due to utilization of EDP systems are given. The advantages of small computers on one hand and of large computers on the other hand are illustrated using the problem of DMF statistics. Some other applications of EDP are mentioned.
As a retrospective study the clinical data of 613 leukaemic children were collected. 269 of them were born in Austria, fell sick between 1967 and 1976 and were not older than 5 years at the onset of disease. BCG-vaccination, which is performed in Austria within the first three days after birth, was checked by means of hospital reports, birth protocols and central BCG record. All data were stored and evaluated by electronic data processing. Besides a significant decrease of mortality, which we could demonstrate in earlier studies, the following correlations between BCG-vaccination of newborn and leukaemia were found: Reduction of morbidity, decrease of case fatality, increase of 5 years survival rate, increase of mean survival time, delayed onset of disease, decrease of frequency of myeloic and chronic leukaemia. With the exception of the slight reduction of morbidity all correlations are significant.
The frequency with which various bacteria are isolated from samples of hospitalized patients and the occurrence of sensitivity to antimicrobial agents in these bacteria are described. Data were collected and summarized by an electronic data processing system. Sensitivity data were obtained with the disc diffusion test carried out by the Bauer/Kirby method. E. coli and S. aureus were the most frequently isolated organisms. Pseudomonas sp. (in 90% Pseud. aeruginosa) took second place behind E. coli among gramnegative rod bacteria. As a rule more than 50% of grampositive and gramnegative bacteria were sensitive to betalactam antibiotics and broad spectrum agents. Aminocyclitols were the most potent drugs. Strains resistant to netilmicin or amikacin were only exceptionally observed. A comparison of the occurrence of sensitive bacteria from 1975 to 1980 revealed that with rare exceptions no decrease of sensitivity to standard drug occurred in E. coli, the Klebsiella-Enterobacter-Serratia group, Pseudo. aeruginosa and S. aureus.
The development of a request for proposal (RFP) to computer hardware and software vendors is described. The RFP functions as a planning document, facilitating communication with a selection of vendors, contract negotiations, and development of acceptance criteria. Development of the pharmacy specifications for the RFP involves evaluating and collecting statistics on the existing manual system, planning future services to be provided by the pharmacy and the hospital, evaluating any computer systems already within the hospital, and assessing the impact of pharmacy's interaction with other departments. This information is translated into descriptions of exactly what is to be provided by computerization. The resulting RFP should include a description of the current manual or electronic data processing system. The priority of each function requested, requests for vendor-specific data, contract information, and instructions for the vendor to use in submitting a proposal. Because the RFP's purpose is to communicate unique system needs, the less specific it is written, the greater the opportunity for misinterpretation.
The use of a tabletop computer for controlled substances distribution is described. The self-contained system uses programs stored on discs to maintain records for floor stock, individual patient orders, and ambulatory patient prescriptions. Three reports are generated daily: (1) a listing of all floor supplies issued on the current date, (2) a listing of all individual patient supply transactions for the current date, and (3) an alphabetical listing of the inventory for controlled substances, including an alert system to identify any item that has fallen below a preselected minimum stock level. The tabletop computer allowed the pharmacy to take advantage of the accuracy and speed of electronic data processing at its own pace, independent of the hospital's main computer system. Because the tabletop computer and the main system both use a common programming language, any programs developed on the tabletop computer can be converted to the main system.
The paper was aimed at an analysis of the health status of 239 workers, basing on routine periodic examinations. One of the versions of preventive examinations set up at the Department of Epidemiology and Statistics, Institute of Occupational Medicine, Lódź, was used for the study. The study involved standardized anamneses meant to detect heart ischaemia and chronic unspecific respiratory tract diseases. In addition, it included sets of questions enabling the detection of diabetes mellitus, disturbances of gallbladder and kidneys, and ulcers. The subjective study included the range of standards sets of arbitrarily selected most important syndromes, which simplifies and shortens documents completion. All this is adjusted to electronic data processing. The authoress quotes her findings, discusses methods and duration, considering also organizational difficulties arising from the studies and possibilities to solve them. Moreover, she attempts at verification of a hypothesis assuming a greater usefulness of using the "tool" for periodic examinations, compared to the routine documentation mandatory in occupational health service.
