Since 1995, the Korean Society for Cytopathology has overseen the Continuous Quality Improvement program for cytopathology laboratories. The Committee of Quality Improvement has carried out an annual survey of cytology data for each laboratory and set standards for proficiency tests.
Evaluations were conducted four times per year from 2008 to 2018 and comprised statistics regarding cytology diagnoses of previous years, proficiency tests using cytology slides provided by the committee, assessment of adequacy of gynecology (GYN) cytology slides, and submission of cytology slides for proficiency tests.
A total of 206 institutes participated in 2017, and the results were as follows. The number of cytology tests increased from year to year. The ratio of liquid-based cytology in GYN gradually decreased, as most of the GYN cytology had been performed at commercial laboratories. The distribution of GYN diagnoses demonstrated nearly 3.0% as atypical squamous cells. The rate for squamous cell carcinoma was less than 0.02%. The atypical squamous cell/squamous intraepithelial lesion ratio was about 3:1 and showed an upward trend. The major discordant rate of cytology-histology in GYN cytology was less than 1%. The proficiency test maintained a major discordant rate less than 2%. The rate of inappropriate specimens for GYN cytology slides gradually decreased.
The Continuous Quality Improvement program should be included in quality assurance programs. Moreover, these data can contribute to development of national cancer examination guidelines and facilitate cancer prevention and treatment.
自1995年以来，韩国细胞病理学学会一直在监督细胞病理学实验室的持续质量改进计划。质量改进委员会每年对每个实验室的细胞学数据进行调查，并制定能力验证标准。
2008年至2018年每年进行四次评估，包括前几年细胞学诊断的统计数据、使用委员会提供的细胞学玻片进行的能力验证、妇科（GYN）细胞学玻片充分性评估以及提交用于能力验证的细胞学玻片。
2017年共有206家机构参与，结果如下。细胞学检查数量逐年增加。由于大多数妇科细胞学检查在商业实验室进行，妇科液基细胞学检查的比例逐渐下降。妇科诊断分布显示非典型鳞状细胞占近3.0%。鳞状细胞癌的比例低于0.02%。非典型鳞状细胞/鳞状上皮内病变比例约为3:1，并呈上升趋势。妇科细胞学中细胞学与组织学的主要不一致率低于1%。能力验证的主要不一致率保持在2%以下。妇科细胞学玻片不适当标本的比例逐渐下降。
持续质量改进计划应纳入质量保证计划。此外，这些数据有助于制定国家癌症检查指南，并促进癌症预防和治疗。
