Use of a clinician reminder system for screening mammography in a public health clinic.

Physician reminder systems have been used to increase the appropriate use of clinical preventive services. These systems, though, have been typically tested in resident clinics. We conducted this study, using a time-series design, to determine if a manual clinician reminder system could increase the use of screening mammography in an urban public health clinic. In the one-year baseline period, 47% of women who were due for a mammogram received the procedure; the corresponding percentage in the one-year intervention period was 72% (P < .0000001). The improvement reflected a large increase in appropriate ordering behavior by primary care providers rather than an increase in patient adherence. This study demonstrates that a noncomputerized reminder system can greatly improve the delivery of screening mammography in a public health clinic setting.
