Regional Cervical Screening Quality Assurance Reference Centres maintain and improve the quality of their local cervical screening programmes by monitoring standards based on a range of outcome measures. The classification of invasive cervical cancer screening histories can aid the interpretation of cervical cancer incidence trends in cervical screening services.
Cervical cancer incidence rates were calculated for cytology laboratory catchment areas, which reflected where local general practitioners sent cervical samples. After reviewing changes in invasive cervical cancer incidence rates in the West Midlands during the period 1988-2004 to identify unusual trends, a detailed retrospective screening history analysis was carried out for one local screening service.
An upward trend in invasive cervical cancer incidence in one laboratory catchment area was caused by an increase in cases occurring in women who had not been routinely screened. Quality assurance data provided supporting evidence for non-attendance at screening during this time.
Assigning a screening status to invasive cervical cancers provides valuable information through which to understand the reasons for changes in cancer incidence with time in local screening services. These data can be used to identify areas of potential concern, thereby facilitating quality assurance activities.
区域宫颈癌筛查质量保证参考中心通过基于一系列结果指标监测标准来维持和提高其当地宫颈癌筛查项目的质量。浸润性宫颈癌筛查史的分类有助于解读宫颈癌筛查服务中宫颈癌发病率的趋势。
计算了细胞学实验室服务区域的宫颈癌发病率，这些区域反映了当地全科医生送检宫颈样本的地点。在回顾1988 - 2004年西米德兰兹郡浸润性宫颈癌发病率的变化以确定异常趋势后，对一项当地筛查服务进行了详细的回顾性筛查史分析。
一个实验室服务区域浸润性宫颈癌发病率的上升趋势是由未进行常规筛查的女性中病例数增加所致。质量保证数据为这段时间内未参加筛查提供了支持证据。
为浸润性宫颈癌确定筛查状态可提供有价值的信息，借此了解当地筛查服务中癌症发病率随时间变化的原因。这些数据可用于识别潜在关注领域，从而促进质量保证活动。
