Observer variation and quality control of cytodiagnosis.
The aim of quality control of a laboratory investigation is to ensure that similar results are obtained on the same material at different centres. To investigate its practicability in cytodiagnosis, the same cytological material was examined independently at six centres. Each centre supplied material from 20 cases, providing a total of 120 cases, ie, 100 cases excluding the donor centre's own m...
متن کاملRespiratory cytodiagnosis: study in observer variation and its relation to quality of material.
Sensitivity and accuracy of cytodiagnosis were assessed in a multicentre study. Six centres each provided sputum cytological material from 20 cases. Each centre screened and reported on the 100 slides provided by the other five centres. The reports were assessed against consensus reference diagnoses, reached by discussion with transparencies, histological sections, and closed-circuit television...

Use of screening phase data to evaluate observer variation of sputum cytodiagnosis as an outcome measure in a chemoprevention trial.
Sputum samples obtained during the screening phase of a chemoprevention trial in heavy smokers were evaluated independently by trained cytotechnologists and classified for degree of cellular atypia according to the method of Saccommano et al. (G. Saccommano et al., Cancer (Phila.), 33: 256-270, 1974). The level of agreement within and between Observers A and B was calculated as the percentage o...
