CONTEXT Medical screening tasks are often difficult, visual searches with low target prevalence (low rates of disease). Under laboratory conditions, when targets are rare, nonexpert searchers show decreases in false-positive results and increases in false-negative results compared with results when targets are common. This prevalence effect is not due to(More)
This report of the Editorial Advisory Board of Cytopathology gives the results of a survey of medical practitioners in cytopathology, which aimed to find out their views on the current situation in undergraduate and postgraduate training in their institutions and countries. The results show that training in cytopathology and histopathology are largely(More)
OBJECTIVE To evaluate virtual microscopy in terms of diagnostic performance and acceptability among practising cytologists. METHODS Twenty-four experienced cytologists were recruited to examine 20 SurePath® cervical cytology slides by virtual microscopy. Diagnostic accuracy was compared with glass slide microscopy using an unbiased crossover experimental(More)
BACKGROUND Acquisition of visual interpretation skills in cytopathology may involve 2 strategies. Analytic strategies require trainees to base their interpretive decisions on carefully considered and often exhaustive cytomorphologic feature lists, a process that can be time-consuming and inefficient. In contrast, nonanalytic pattern recognition strategies(More)
OBJECTIVE The discrimination of hyperchromatic crowded cell groups (HCCGs) in cervical cytology is a difficult and error-prone interpretive task. While the classic features of dyskaryosis are of undoubted value, the contribution of size, shape and colour intensity of HCCGs is less certain. This study employed morphometric analysis to determine whether HCCG(More)
BACKGROUND Cytologists must learn how to discriminate cells that might be visually very similar but have different neoplastic potential. The mechanism by which trainees learn this task is poorly researched and is the focus of the current investigation. Cognitive science offers a theoretical platform from which to design meaningful experiments that could(More)
OBJECTIVE Visual distraction in cytopathology has not been investigated previously as a source of diagnostic error, presumably because the viewing field of a conventional light microscope is considered to be large enough to minimise interference from peripheral visual stimuli. Virtual microscopy, which involves the examination of digitised images of(More)
