The National Cervical Screening Programme was introduced to increase population coverage while reducing the overscreening of women at low risk.
To describe the frequency with which cervical smears are unnecessarily repeated within the prescribed screening interval.
All cervical smears taken in a primary care setting in Manchester from women aged 20-64, during 1988-92, were identified. A smear was considered unscheduled if it was taken within 30 months of a preceding smear and if there was no clinical indication or laboratory recommendation for an early repeat smear.
A total of 100 134 smears were identified from 85 594 women attending 130 general practices and 40 NHS community clinics; 12 633 women subsequently had 14 702 unscheduled smears; 50% of the unscheduled smears were taken by 18% of the general practices and 8% of the NHS community clinics.
If they are replicated elsewhere, these findings suggest a substantial disinvestment opportunity.
国家宫颈筛查计划旨在提高人群覆盖率，同时减少对低风险女性的过度筛查。
描述在规定的筛查间隔内不必要重复进行宫颈涂片检查的频率。
确定了1988 - 1992年期间在曼彻斯特初级保健机构对20 - 64岁女性进行的所有宫颈涂片检查。如果涂片是在前一次涂片后的30个月内进行的，并且没有临床指征或实验室建议进行早期重复涂片，则该涂片被视为非计划内的。
从130家全科诊所和40家国民保健服务社区诊所的85594名女性中总共识别出100134次涂片；随后，12633名女性进行了14702次非计划内涂片；50%的非计划内涂片是由18%的全科诊所和8%的国民保健服务社区诊所进行的。
如果这些结果在其他地方得到重现，这些发现表明存在大量的撤资机会。
