Repeat Dual-Energy X-Ray Absorptiometry (DXA) Resulting From Reminder Letters For Women With a Baseline Abnormal DXA

The objective was to assess the effects of reminder letters on women returning for repeat bone density. We queried our clinical data repository to identify all women undergoing dual-energy X-ray absorptiometry (DXA) during the entire 2003 calendar year. Women with abnormal DXAs were entered into a database for reminder letters. The electronic medical record was then reviewed for the presence of the reminder letter and whether any repeat DXA scan was done. Approximately half of the women returned for repeat DXA of this group, approximately one-third were improved, one-third deteriorated, and the remaining were unchanged. We suggest a clinical benchmark of a minimum of 50% of women with abnormal bone density returning for repeat DXA on the same machine at a DXA imaging center should be a quality improvement goal. Further research into exploring why patients do not return for serial DXA and the impact of reminder letters on improving treatment outcomes should be conducted.
