Demographic, clinical, and financial factors relating to the completion rate of screening mammography.
A retrospective analysis of the UCLA Family Health Center Research Data Base was performed to determine the relationship between completion rates of screening mammography and various patient demographic, clinical, and financial factors. Data from a 16-month period, from July 1984 through October 1985, were analyzed. Eight hundred twenty-seven women over 50 years of age were seen in the UCLA Family Health Center at least once during the study period. One hundred thirty-six (16.4%) of these women had screening mammography performed. Health insurance coverage was an important determinant of mammography completion. Patients covered by a health maintenance organization were 2.5 (P less than .05) times more likely to receive screening mammography. Uninsured patients were only 0.5 times as likely to have this procedure performed. The completion rate for screening mammography increased significantly with increasing number of visits during the study period (P less than .001). The age groups analyzed were significantly associated with completion rate. Marital status had a significant relationship to completion rate, but this was due to a lower completion rate in the group of patients whose marital status could not be determined. The employment status could not be evaluated due to the high rate of missing data. Race, smoking status, alcohol consumption, and the sex and training level of the primary provider were not found to be significantly associated with screening mammogram completion rates.
