摘要:
A slide circulation scheme measuring cervical screening performance of individual cytologists in 15 laboratories in Yorkshire Regional Health Authority is described. The advantages and disadvantages are compared with the current National Proficiency Testing (NPT) scheme. The results indicate that a slide circulation scheme can be successfully used in cervical cytology external quality assessment (EQA). Levels of participation are better than those currently achieved by regional variations of the NPT scheme, and the use of laboratory consensus in the selection of scoring slides appears to be no less valid than the use of a pre‐selected slide pool assembled by an expert panel. The volume of data accumulated in one round is considerably greater than that achieved by proficiency testing and the educational value is regarded as high. However, the scheme is very time consuming for participants and consequently expensive for laboratories. The lack of external supervision increases the risk of unfair practices within individual laboratories. Because of these problems, Yorkshire has now switched to an NPT schem
