Objective: To monitor the effectiveness of the cervical screening programme and identify suboptimal management in order to improve patient care.
Design: Retrospective study.
Setting: A university hospital serving a population of 1 million people.
Population: All women diagnosed with a cervical cancer between 2003 and 2006.
Methods: Analysis of data from invasive cervical cancer reviews.
Main outcome measure: Categorisation of cervical cancer cases according to the Invasive Cervical Cancer Audit classification.
Results: Eighty-seven women were diagnosed with cervical cancer during the 3-year study period. The 'lapsed attender' group accounted for the greatest number of cases (30%), followed by screen detected (26%), interval cancers (13%), never attended (12%), lost to follow-up (10%) and never invited (9%). Women who had never attended for cytology presented with higher stage disease, stage-II or above, compared with the screen-detected cases: 60% were stage II or above, compared with 13.0%, Chi-square P = 0.018. The most frequently identified screening programme problem was patient compliance, which was determined to be the principle contributing factor in 39 cases (45%) and a secondary factor in a further ten cases.
Conclusions: The categorisation of cervical cancer cases has the potential of yielding invaluable information for improving programme effectiveness. Patient compliance is the greatest challenge to the screening programme, and the need for regular screening and adherence to follow-up regimens needs to be reinforced in order to maximise the efficacy of the national screening programme.
