A review of the first 14 years of the New York State Proficiency Testing Program in cytology shows the value of external quality-control evaluation based upon an established standard of performance as a prerequisite for licensure by a regulatory agency. Performance by participating laboratories has improved over the 14-year period. Hospital and independent(More)
OBJECTIVE To describe a method of calculating sample size if rescreening of cytologic material becomes necessary for legal or other reasons. The number of specimens to be reexamined must be large enough to provide adequate confidence in the results and small enough to minimize the cost of investigation. CONCLUSION Except under very unusual conditions, the(More)

Although ageing is a biological process, it does not occur in a social vacuum, so it can also be understood as a social experience and in sociological terms. Social theories of(More)
The New York State Proficiency Testing Program in Cytology is a three-part program consisting of an annual inspection, biennial proficiency tests, and ongoing education programs. Clinical laboratory consultants inspect laboratories' internal quality control and compliance with regulatory standards. In the proficiency test, cytotechnologists screen test(More)
A study was conducted to ascertain the relationships among different competence assessment methods for cytotechnologists. Of primary concern was the extent to which examinations using multiple choice questions, color plate photomicrographs and filmstrip formats measure abilities in common with or predict performance levels on a practical,(More)
Proficiency tests in cytology classify a certain proportion of cytologists inaccurately. Some competent cytologists fail during the testing procedure ("false-negative proficiency test" or "type I error") while some individuals who should fail do pass the test ("false-positive proficiency test" or "type II error"). In other words, success or failure during(More)
