title: Physician-reported determinants of screening mammography in older women: the impact of physician and practice characteristics.
abstract: OBJECTIVE
  Despite having markedly higher breast cancer risk, compliance of older women with screening mammography has been poor. This study was undertaken to determine which physician and patient practice characteristics were associated with high self-reported mammography referral rates for older women.
  
  
  METHODS
  Primary care physicians (n = 129) from three socioeconomically diverse communities in Los Angeles were surveyed. Agreement with annual screening and self-reported referral rates were assessed for two groups of women, those 65 to 74 years of age and those 75 years and older. Screening outcomes were compared with physician and patient practice characteristics using bivariate and multivariate techniques.
  
  
  RESULTS
  Although 73% of physicians agreed with annual screening of women aged 65 to 74 years, only 24% of physicians reported actually screening most women seen in this age group. Similarly, 57% of physicians agreed that women age 75 years and older should be screened annually, but only 21% reported recommending mammograms for most women seen in this age group. In multivariate analysis, white physicians (adjusted OR = 9.1), younger physicians (adjusted OR = 3.85), and those who used the American Cancer Society's low cost mammography projects (adjusted OR = 5.01) were more likely to report screening the majority of women seen.
  
  
  CONCLUSIONS
  This study suggests that although physicians' intentions to screen older women may be relatively high, a gap exists between intentions and what is reported to be accomplished in practice. Race/ethnicity and physician specialty were the two strongest predictors of high self-reported referral rates, suggesting that targeted interventions may be useful.
