Audit of histopathological activities in the laboratories of 7 general hospitals. 1. Types of resources and quantitative aspects of the workload

: Following a major reorganization of the National Health Service, competition for resources will depend to a great extent on the quality of the service offered, and audit will be of increasing importance. The present investigation deals with the quantitative aspects of the histopathology workload. A retrospective analysis of the biopsy handling of 1,000 consecutive cases was conducted in each histopathology lab of seven general hospitals. The data collected included information on specimen type, diagnosis, block/section/stain details for each specimen, as well as information about human resources, total workload and technical equipment. Among the seven labs, the histopathology workload ranged between 6,600 and 15,600 cases/year. The workload per person/year ranged between 1,400 and 2,600 (mean 1,900) for pathologists, between 800 and 3,000 (mean 1,500) for technicians, and between 2,200 and 8,300 (mean 4,400) for secretarial staff. The prevalence of biopsy fragments (endoscopic, endometrial curettage , etc.), "small" surgery (skin, appendix, gallbladder, etc.) and surgery was, respectively, between 42 and 50%, 34 and 47%, 9 and 21%. In all labs but one, 80% of cases were within 1-3 blocks; the seven labs had a mean of blocks/case ranging from 1.8 to 4.0 (total mean = 2.8). Differences in performing special stains were astonishing: one lab performed special stains in about 40%, and another in only 0.6% of cases (mean of the seven labs = 15%). Finally, the labs performed immunohistochemical stains within a range of 2.7-8% of cases (mean of the seven labs = 4.6%). The data we have collected provided baseline information on the laboratory running, and this is likely to be an integral part of laboratory administration in the near future.
