Monitoring the relative frequency of the interpretations of atypical squamous cells (ASC) and squamous intraepithelial lesions (SIL) has been proposed as a quality control measure. To assess its value, an ASC/SIL ratio was calculated every 6 months for 3.5 years, and confidential feedback was provided to 10 cytopathologists (CPs). By using simple regression analysis, we analyzed the initial and final ASC/SIL ratios for individual CPs and for the entire group. The ratio was below the upper benchmark of 3:1 for all but 1 CP during every 6-month period. The ratio for all CPs combined showed a downward trend (from 2.05 to 1.73). The ratio for 6 CPs decreased, and for two of them the decrease was statistically significant. One CP showed a statistically significant increase in the ASC/SIL ratio. The decrease for some CPs likely reflects the salutary effect of confidential feedback and counseling.
监测非典型鳞状细胞（ASC）和鳞状上皮内病变（SIL）的解读相对频率已被提议作为一种质量控制措施。为评估其价值，在3.5年的时间里每6个月计算一次ASC/SIL比率，并向10位细胞病理学家（CP）提供保密反馈。通过简单回归分析，我们分析了个体CP和整个组的初始和最终ASC/SIL比率。在每6个月的时间段内，除1位CP外，所有CP的比率均低于3:1的上限基准。所有CP的综合比率呈下降趋势（从2.05降至1.73）。6位CP的比率下降，其中两位的下降具有统计学意义。1位CP的ASC/SIL比率有统计学意义的增加。一些CP的下降可能反映了保密反馈和咨询的有益效果。
