Mb. Barton et al., Increased patient concern after false-positive mammograms - Clinician documentation and subsequent ambulatory visits, J GEN INT M, 16(3), 2001, pp. 150-156
OBJECTIVE: To measure how often a breast-related concern was documented in
medical records after screening mammography according to the mammogram resu
lt (normal, or true-negative vs false-positive) and to measure changes in h
ealth care utilization in the year after the mammogram.
DESIGN:Cohort study.
SETTING: Large health maintenance organization in New England.
PATIENTS: Group of 496 women with false-positive screening mammograms and a
comparison group of 496 women with normal screening mammograms, matched fo
r location and year of mammogram.
MEASUREMENTS AND MAIN RESULTS: 1) Documentation in clinicians' notes of pat
ient concern about the breast and 2) ambulatory health care utilization, bo
th breast-related and non-breast-related, in the year after the mammogram.
Fifty (10%) of 496 women with false-positive mammograms had documentation o
f breast-related concern during the 12 months after the mammogram, compared
to 1 (0.2%) woman with a normal mammogram (P =.001). Documented concern in
creased with the intensity of recommended followup (P =.009). Subsequent am
bulatory visits, not related to the screening mammogram, increased in the y
ear after the mammogram among women with false-positive mammograms, both in
terms of breast-related visits (incidence ratio, 3.07; 95% confidence inte
rval [CI], 1.69 to 5.93) and non-breast-related visits (incidence ratio, 1.
14; 95% CI, 1.03 to 1.25).
CONCLUSIONS: Clinicians document concern about breast cancer in 10% of wome
n who have false-positive mammograms. and subsequent use of health care ser
vices are increased among women with false-positive mammogram results.
