title: Effectiveness of a call/recall system in improving compliance with cervical cancer screening: a randomized controlled trial.
abstract: OBJECTIVE
  To determine the effectiveness of a simple call/recall system in improving compliance with cervical cancer screening among women not screened in the previous 3 years.
  
  
  METHODS
  Prospective randomized controlled study.
  
  
  METHODS
  Two family medicine clinics (1 urban, 1 rural) affiliated with Memorial University of Newfoundland, St. John's.
  
  
  METHODS
  A sample of women aged 18-69 years who were listed as patients of the clinics but who had not had a Papanicolaou test (Pap test) within the 3 years before the start of the study. Of 9071 women listed as patients 1360 (15.0%) had not undergone screening in the previous 3 years. A random sample of 650 were selected, 209 of whom were excluded because they had had a hysterectomy, had had a recent Pap test, had moved or had records containing clerical errors. This left 441 women for the study.
  
  
  METHODS
  The 221 women in the intervention group were sent a letter asking them to seek a Pap test and a reminder letter 4 weeks later. The 220 in the control group were sent no letters.
  
  
  METHODS
  Number of women who had a Pap test within 2 months and 6 months after the first letter was sent.
  
  
  RESULTS
  Within 2 months, more women in the intervention group than in the control group had been screened (2.8% [5/178] and 1.9% (4/208] respectively). There was also a difference between the overall proportions at 6 months (10.7% [19/178] and 6.3% [13/208] respectively). None of the differences was statistically significant.
  
  
  CONCLUSIONS
  A letter of invitation is not sufficient to encourage women who have never or have infrequently undergone a Pap test to come in for cervical cancer screening. The effectiveness of added recruitment methods such as opportunistic screening by physicians, follow-up by telephone and the offer of a specific appointment should be evaluated.
