Patient reminder letters to promote annual mammograms: a randomized controlled trial.

BACKGROUND: This study assessed the effects of a reminder letter from a physician (relative to a mammography facility letter or no letter) on appointment compliance among women 50-74 years of age due for an annual screening mammogram. METHODS: A total of 1,562 women were randomly as signed to the groups. Each Group 1 subject received a reminder letter from her physician, each Group 2 subject received a reminder letter from her mammography facility, and Group 3 served as a control group. RESULTS: The return rates for Groups 1, 2, and 3 were 47.7, 46.6, and 28.3%, respectively; the overall difference was significant using a chi(2) analysis (P < 0.001). Bonferroni pairwise comparisons indicated no difference between Groups 1 and 2 but significant differences (P < 0.001) between Group 3 and the other two groups. Logistic regression indicated that relative to Group 3, the adjusted odds of returning for Groups 1 and 2 were 2.37 and 2.24, respectively. CONCLUSIONS: Mammography providers and their patients likely will benefit from in-reach reminder systems. Physicians who do not use reminder systems should refer their patients to facilities that use these systems.

Rates and correlates of discomfort associated with mammography.

PURPOSE: To explore the rates and correlates of discomfort at mammography in asymptomatic women aged 50-74 years from six San Diego, Calif, mammography facilities. MATERIALS AND METHODS: Subjects (N = 1,800) completed a 43-item telephone interview approximately 3 weeks after screening mammography. Bivariate associations between variables were analyzed with chi(2) analysis. Logistic regression was used to assess the independent predictors of discomfort at mammography while controlling for all other factors. RESULTS: Nine hundred thirty-three (52%) women reported moderate to extreme discomfort at mammography. Discomfort was not related to the intention to undergo future mammography (P =.95). Factors that were significantly associated with discomfort in multivariate analyses were facility (P <.001), satisfaction with care (P <.04), and perception of the technologist's "roughness" (P <.001). CONCLUSION: Discomfort, although not related to the intention to undergo future mammography, had a relatively high incidence.
