Therapeutic use of albumin.

Increasing use of normal human serum albumin may be contributing to the rising cost of medical care. To investigate whether albumin is extensively overused or abused, a study of the quality of albumin use was conducted in a Veterans Administration Hospital. Specific criteria for appropriate use were developed using guidelines defined at a national symposium. A review of use during a three-month period showed that surgery patients received 91% of the albumin administered during that period; of the total amount administered, 41% was used inappropriately; the decision to administer albumin to patients undergoing surgery appeared to be correct only 29% of the time; and an estimated $40,000 was spent on inappropriately used albumin at this hospital in 1977.

Costs and Cost Analysis

Quantification of visual fields for statistical analysis.

The importance of visual fields in the study of ocular vascular disorders prompted the development of a method to convert visual fields plotted on a Goldmann perimeter into a digital form so that the data could be analyzed and stored by a computer. An instrument called a scotometer was designed to measure the visual fields and the various scotomata, and a data coding form was developed to facilitate the entry of the data into the computer. After extensive testing, this method is now being used in several clinical trials. Statistics have been computed that support the reliability of the coding process.
