title: Use of screening mammography by general internists.
abstract: While physician endorsement has been shown to be highly important in motivating women to obtain screening mammograms, there is evidence that doctors do not refer women for the procedure as often as they should. The objective of this study was to help understand why physicians do not routinely utilize screening mammography. Randomly selected Washington State general internists were surveyed by mail, concerning mammography, during 1989. An expanded theory of reasoned action was used as a broad conceptual framework for considering factors potentially associated with use. The survey response rate was 66%, yielding a study sample of 85. Only 38% of the respondents reported they always ordered mammograms for women aged 50 years and over during preventive office visits. Nearly half (43%) had no reminder system for the test. Correlates of use included beliefs concerning the screening behavior of other doctors, the location of mammography facilities in relation to physician offices, and age. Physician-related barriers, such as doubts about effectiveness, were found to affect use more than patient-related barriers, such as cost. The recommendations of professional organizations were shown to have been important in influencing physician use of screening mammography. This study indicates a proportion of general internists are not routinely ordering mammograms for their age-eligible female patients. The findings identify barriers to use of mammography that need to be overcome if national efforts to promote use of the procedure by primary care physicians are to succeed. Implications for intervention are reviewed.
