title: A randomised controlled trial of strategies to prompt attendance for a Pap smear.
abstract: OBJECTIVE
  To assess the comparative efficacy, by randomised controlled trial, of three interventions designed to encourage "at risk" women to have a Pap smear: an educational pamphlet; letters inviting attendance at a women's health clinic; and letters from physicians.
  
  
  METHODS
  Subjects at risk for cervical cancer who had not been adequately screened were identified by a random community survey and randomly allocated to one of the intervention groups or a control group. Six months after intervention implementation, a follow up survey assessed subsequent screening attendance. Self report was validated by comparison with a national screening data base.
  
  
  RESULTS
  A significantly greater proportion of women (36.9%) within the group receiving a physician letter reported screening at follow up than in any other group (P = 0.012). The variables most strongly predicting screening attendance were: age, perceived frequency of screening required, use of oral contraceptives, and allocation to receive the physician letter intervention.
  
  
  CONCLUSIONS
  The relative efficacy of the GP letter in prompting screening attendance shows that this strategy is worthy of further investigation. There remains a need to examine the barriers to screening for older women, and to develop tailored strategies for this population.
