Abstract

Rapid prescreening (RPS) is a powerful tool to measure and improve performance in the cytology laboratory. Long-term use of RPS has been shown to result in improved sensitivity and precision in routine screening. The effect of long-term RPS on RPS itself is not known. We compared the sensitivity of 100% RPS of Surepath™ liquid-based cytology over a 4-year period in a laboratory of 11 cytotechnologists (CTs). In comparison with the first 2 years, RPS for the laboratory showed a significant increase in sensitivity for all abnormalities (72.2% vs. 67.3%, P < 0.001) and ASCUS + LSIL (68.5% vs. 62.1%, P < 0.001). For individual CTs s, the lowest sensitivity for all abnormalities increased from 59.0 to 63.2%, whereas, for HSIL, it increased from 71.4% to 75.0%. We conclude that long-term use of RPS leads to significant increase in the sensitivity of RPS.
