Use of patient reminder letters to promote cancer screening services in women: A population-based study in Wisconsin.

Background: Patient reminder letters are an effective method of promoting cancer screening services in women; however, information on their actual use in a population setting is lacking.
Methods: Data were obtained from a population-based, random digit dial telephone survey of 896 adult women living in Wisconsin. Respondents were asked if they had received a reminder letter for Pap or mammography screening within the past year.
Results: Among women aged >/=18 years, 12.9% (95% confidence interval [95% CI] = 10.1-15. 6) received a Pap test reminder within the past year, while 13.0% (95% CI = 9.3-16.7) of women aged >/=40 years received a mammography reminder. Women without health care coverage were unlikely to receive either type of reminder. Current compliance with screening recommendations was greater among those women who received a reminder letter for Pap tests (94.3 versus 78.1%, P < 0.0001) and for mammography (81.7 versus 59.4%, P < 0.001). In contrast to the infrequent use of cancer screening reminders, 54.2% (95% CI = 50. 1-58.3) and 72.7% (95% CI = 67.6-77.8) of women reported receiving a reminder letter from their dentist or veterinarian, respectively.
Conclusions: Reminder letters for cancer screening services were rarely utilized in this study population. Receipt of a reminder letter was associated with greater compliance with current screening recommendations.
