Barriers to follow‐up of abnormal screening mammograms among low‐income minority women

OBJECTIVE: To describe factors related to compliance diagnostic follow-up among minority women of low socioeconomic status with abnormal screening mammograms. METHODS: A retrospective cross-sectional survey using a structured telephone interview. Three cancer screening clinics at an urban inner-city public hospital. All women with abnormal screening mammograms between September 1990 and January 1992 were eligible; women were interviewed in August 1992. Abnormal mammograms were those requiring specific, non-routine clinical follow-up; non-compliance was defined as delayed follow-up (four to six months after the date of the mammogram), or no follow-up at the time of interview (more than 6 months after abnormal). RESULTS: Sixty-two of 442 screened women had abnormal results; the overall rate of non-compliance with follow-up was 50%. Among the 42 (68%) women who agreed to be interviewed, non-compliers were less likely to state that they had been told to receive follow-up than compliers (65% versus 100%; p = 0.008). Non-compliant women were less likely to have suspicious mammography interpretations (p = 0.05), and more likely to report barriers to follow-up, such as cost of lost wages and medical care, system barriers, or fears, than compliant women (61.9% versus 9%, p = 0.01). There were no differences between the two groups for age, education, insurance, source of care, family history, knowledge or attitudes. CONCLUSIONS: These preliminary results suggest that follow-up of low income, minority women with abnormal screening mammograms could be enhanced by improved communication of results. Future studies should extend these findings with larger samples and in other settings and populations.
