Compliance with recommended follow-up after percutaneous breast core biopsy.

Abstract

The purpose of this study was to use information from an established patient tracking system to evaluate patient outcome and assess patient compliance with recommended follow-up after percutaneous breast core biopsy. All breast core biopsies performed from January 1994 through February 14, 1996, that used stereotaxic or sonographic guidance were reviewed. Clinical, imaging, and pathologic findings were correlated with patient outcomes established by recommended surgical and nonsurgical follow-up. Of 160 core biopsies in 153 women, 30 biopsies were performed on the basis of clinical complaints. One hundred thirty lesions were detected by mammography or sonography or both. Of the 70 lesions recommended for surgical excision, 52 (74%) had documented surgical outcomes. Mammographic surveillance was recommended for 90 lesions, of which 10 (11%) had resolved at the time of this study, 49 (54%) were on track toward 3-year lesion stability, 21 (23%) were being followed up elsewhere, four (4%) were lost to physicians, and six (7%) were lost to follow-up for other reasons. Known compliance with follow-up recommendations among these 153 patients who underwent breast core biopsy was higher for patients receiving surgical recommendation (74%) than for patients receiving imaging surveillance recommendation (54%). Problems tracking patients were caused both by loss of patients to follow-up and by incomplete reporting from referring physicians.
