The size and scope of this study for 1983 has been only briefly described by the few summary results that we have been able to put within this single article. Thousands of pages of data exist describing and detailing the complete statistical base of information that now exists on hospital data processing over the past 3 years. One need no longer guess or approximate what the industry is doing. Quantitative data are now available that we hope will lead to good decisions, good products, and good services. The 1982 and 1983 data base is now complete, along with the statistical analysis of information. The 1984 survey is now being distributed, and results should be complete in early 1985. For companies that are involved in this industry, the survey produces 11 volumes of information that are called Market Reports. For hospitals primarily concerned about the acquisition of equipment, there exist 8 volumes covering the major systems areas. For further information on these documents or any of the data elements contained within the survey, please address your questions to the Medical Systems Division at the University of Florida, Gainesville, Florida.
Proposing that pathology reorganize, the author introduces a role model for clinical pathology that contains skills and capabilities not currently offered in the clinical practice of medicine. This proposed rebuilding of a clinical discipline, to avoid continued degradation of the pathologist's role in the practice of medicine, will require teaching institutions to instill a new concept of clinical pathology, and the author pinpoints the tool that will be required to make this urgently needed transition to a new type of practice.

A study of healthy subjects was conducted at the University of Florida wherein 52 routine clinical laboratory procedures were measured durng normal operation of the clinical laboratories. The goal of the study ws to quantify nonsignificant personal variation for a number of laboratory procedures referred to as a "Clinical Delta Range," which results from taking several samples per day, several days during the week. Results of the statistical test of hypotheses are given together with summary statistics for the 52 different laboratory procedures. A discussion of the model and testing methods are provided. Further, examples are given to illustrate the methodology and certain limitations associated with the concept of a Clinical Delta Range.
Changes are proposed regarding the presentation of laboratory information. More definitive statements are required for reference limits, sampling variance (the Clinical Delta Range), and multivariate group analysis of large test batteries. To make this transition possible, laboratory reports should be classed so that the practicing physician has some measure of confidence in the product and its compatability with other sources. The proposal extends to the range of financial reimbursement and suggests that class standing be issued by an accrediting agency and support a structured level of payment.

This paper presents points brought out in a panel discussion held at the 12th Hawaiian International Conference on System Sciences, January 1979. The session was attended by approximately two dozen interested parties from various segments of the academic, government, and health care communities. The broad categories covered include the specific problems of government regulations and their impact on specific clinical information systems installed at The University of Texas Health Science Center at Dallas, opportunities in a regulated environment, problems in a regulated environment, vendor-related issues in the marketing and manufacture of computer-based information systems, rational approaches to government control, and specific issues related to medical computer science.
The large volumes of laboratory data currently available in clinical practice can lead to erroneous conclusions. Our current statistical interpretation of these data is univariate (one variable at a time) and often not age- and sex-corrected. Using an optimal technique of multivariate analysis, a SMAC profile of 19 tests performed on normal subjects resulted in over a 500% improvement in defining the reference range. Using physiologic subsets of the SMAC profile for patients, improvements in interpretation of between 100% and 300% are possible. Results indicate a serious clinical problem that will require modification of laboratory reports using modern technology as an adjunct for diagnostic medicine.
A regional or hospital-based "reference" value study is well within the range of every clinical laboratory. A program is described that samples one to two "health" subjects each working day under tightly controlled conditions. Sixty-seven variables are tested simultaneously to provide univariate age and sex ranges, and variance/covariance matrices from which associated correlation coefficients are obtained. This ongoing "reference" value program offers essential information for both univariate and multivariate interpretations along with validation and quality control for certain methods within the clinical laboratory.

A Laboratory Information System (LIS) is a convenient organization of programs and hardware designed to meet the health care delivery needs of a department of pathology. A full service LIS is now a commercially viable product and after 2 years of experience, certain desirable design features are evident for a second generation system. Such variables as hardware configuration, physical plant, libraries, diagnostic algorithms, system usage and surveillance, and manpower and human engineering are now significant operational features and essential for LIS acceptance by a department of pathology as well as the practicing medical staff.
A PSRO audit of laboratory performance can be achieved without additional manpower if tied into the communication and laboratory system of the hospital. Techniques are described which provide immediate physician feedback for education. Cumulative statistics are recorded for internal laboratory review and for validation of technical performance. Through proper system designs, significant improvements can be achieved which do decrease health care costs and optimize professional interaction.
