title: Vaginal vault cytology tests: analysis of a decade of data from a UK tertiary centre.
abstract: OBJECTIVE
  To examine temporal trends in the use of vault cytology tests in primary and secondary care and the demographics of those women tested.
  
  
  METHODS
  Retrospective analysis of routinely collected data concerning women who had a vault cytology test processed during a 10-year period (1 April 1995 to 31 March 2005) at Birmingham Women's NHS Foundation Trust.
  
  
  RESULTS
  A total of 8457 vault cytology tests from 3164 women (range 1-17 tests, median = 2) were processed, representing approximately 2% of the cervical cytology workload of the Department of Cytopathology at Birmingham Women's Hospital. There was a significant reduction in annual numbers processed (Pearson correlation -0.958, P < 0.001). Significant abnormalities (mild dyskaryosis or worse) were detected in 4.5%, with malignancy being detected in <0.1%. The unsatisfactory cytology test rate was 10.7% overall. There was a reduction in the numbers of vault cytology tests coming from the community, hospital outpatient clinics and operating theatres over time (χ(2) for linear trend = 139.53, 9 d.f., P < 0.0001). Tests originating from community settings had the lowest disease detection rates: no malignancies and only two severe abnormalities were detected from almost 4000 primary care samples; abnormal results represented 2.8% (n = 113), of which the majority (n = 73) were borderline results. All cancers (n = 8) were detected in samples taken in gynaecology and colposcopy clinics.
  
  
  CONCLUSIONS
  Vault cytology test usage appears to be reducing, particularly from outpatient clinics and primary care. Community detection rates are very low. Further research is required to establish the true costs and benefits of vaginal vault cytology.
