Relationship between haemoglobin and the other clinical and laboratory parameters in rheumatoid arthritis.

A retrospective study is reported of 160 patients with definite or classical rheumatoid arthritis, in which changes in haemoglobin concentration were analysed against changes in various routine clinical and laboratory indices of disease activity over a period of time. Although statistically significant correlations were found between haemoglobin concentrations and the articular index of joint tenderness, serum albumin concentration, and erythrocyte sedimentation rate at one point in time, significant relationships in changes in haemoglobin concentration were only found with changes in the latter two laboratory indices. The significant correlations were weak and less important than the cumulative effect of unknown variables in determining haemoglobin level. The study shows that the routine clinical and laboratory parameters of disease activity in rheumatoid arthritis are of no value in predicting the haemoglobin concentration.

Pesticide and mercury residues in commercially grown catfish.

In 1970, 54 commercial catfish farms in Arkansas and Mississippi were sampled for pesticide and mercury residues. Pesticide residues above FDA action levels were detected in 15 percent of the fish samples. Data on residues in sediment, fish feed, and source water suggest that fish were not being contaminated from these sources. Average fish residue per county was, however, strongly correlated with the percent of total acres planted in cotton and soybeans. Results strongly suggest that cotton production was the primary source of contamination. Actual routes of movement have not been clearly defined but aerial transport seems most probable.

Family physicians' perceptions of psychosocial disorders: survey report and educational implications.

One-hundred seventy-seven family physicians were surveyed regarding their perceptions of the types of psychosocial problems encountered in their practices, the amount of time they felt they devoted to each problem, and their interests regarding continuing psychiatric education. Patients with "multiple somatic complaints" and "symptoms of emotional distress" were reported as being encountered most frequently. Marital and family problems, alcoholism and sexual dysfunction were also ranked highly. The physicians indicated the highest interest in managing these disorders in addition to treatment of the suicidal patient. The implications of these results for psychiatric educators and liaison psychiatrists are discussed. The authors recommend using DSM-III diagnostic criteria applicable to these syndromes in formulating educational programs for primary care physicians.

Organizational innovation and the laboratory information system.

There is an urgent need for more innovation in health care and in clinical laboratories. Innovation can be divided into five separate categories: core products, components of the core products, production processes, uses of products, and the organization of production. Organizational innovation is an important as technological advances in increasing the quality and efficiency of clinical laboratories. The use of a laboratory information system (LIS) can stimulate organizational innovation such as the assignment of computer-oriented tasks to personnel within individual clinical laboratories. The authors refer to such LIS support personnel as "hidden personnel" and suggest that such a shift of responsibility empowers laboratory professionals and makes them stakeholders in automated information processing.

The deployment of information technology in clinical laboratories and its impact on professional roles.

New information technology is deployed in hospital clinical laboratories to increase both the quality and efficiency of laboratory operations. Although total laboratory expenses may rise as a result of technology deployment, the average cost per test may decline. S-curves can be used to illustrate the effects of new information technology--such as a laboratory information system (LIS)--on the useful output and use of resources in laboratories. Major changes are now occurring as a result of the deployment of information technology, most notably in the area of automated information management. The role of laboratory professionals must be modified in response to this new information environment. The generation of information within clinical laboratories should be considered as the beginning--not the end--of the responsibility of laboratory professionals.
