Résumé
Breast core needle biopsy (CNB) can obviate the need for breast surgery in patients with an unknown breast lesion; however, variation in compliance with this guideline may represent a disparity in health care and a surrogate measure of unnecessary surgery. We evaluated variation in breast CNB rates prior to initial breast cancer surgery. We performed a retrospective analysis using Medicare claims from 2015 to 2017 to evaluate the proportion of patients who received a CNB within 6 months prior to initial breast cancer surgery. Outlier practice pattern was defined as a preoperative CNB rate ≤ 70%. Logistic regression was used to evaluate surgeon characteristics associated with outlier practice pattern. We identified 108,935 female patients who underwent initial breast cancer surgery performed by 3229 surgeons from July 2015 to June 2017. The mean CNB rate was 86.7%. A total of 7.7% of surgeons had a CNB performed prior to initial breast surgery ≤ 70% of the time, and 2.0% had a CNB performed ≤ 50% of the time. Outlier breast surgeons were associated with practicing in a micropolitan area (odds ratio [OR] 1.88, 95% confidence interval [CI] 1.29-2.73), in the South (OR 1.84, 95% CI 1.20-2.84) or West region (OR 1.78, 95% CI 1.11-2.86), > 20 years in practice (OR 1.52, 95% CI 1.09-2.11), and low breast cancer surgery volume (< 30 cases in the study period; OR 4.03, 95% CI 2.75-5.90). Marked variation exists in whether a breast core biopsy is performed prior to initial breast surgery, which may represent unnecessary surgery on individual patients. Providing surgeon-specific feedback on guideline compliance may reduce unwarranted variation.

BACKGROUND
BACKGROUND
Breast core needle biopsy (CNB) can obviate the need for breast surgery in patients with an unknown breast lesion; however, variation in compliance with this guideline may represent a disparity in health care and a surrogate measure of unnecessary surgery. We evaluated variation in breast CNB rates prior to initial breast cancer surgery.
METHODS
METHODS
We performed a retrospective analysis using Medicare claims from 2015 to 2017 to evaluate the proportion of patients who received a CNB within 6 months prior to initial breast cancer surgery. Outlier practice pattern was defined as a preoperative CNB rate ≤ 70%. Logistic regression was used to evaluate surgeon characteristics associated with outlier practice pattern.
RESULTS
RESULTS
We identified 108,935 female patients who underwent initial breast cancer surgery performed by 3229 surgeons from July 2015 to June 2017. The mean CNB rate was 86.7%. A total of 7.7% of surgeons had a CNB performed prior to initial breast surgery ≤ 70% of the time, and 2.0% had a CNB performed ≤ 50% of the time. Outlier breast surgeons were associated with practicing in a micropolitan area (odds ratio [OR] 1.88, 95% confidence interval [CI] 1.29-2.73), in the South (OR 1.84, 95% CI 1.20-2.84) or West region (OR 1.78, 95% CI 1.11-2.86), > 20 years in practice (OR 1.52, 95% CI 1.09-2.11), and low breast cancer surgery volume (< 30 cases in the study period; OR 4.03, 95% CI 2.75-5.90).
CONCLUSIONS
CONCLUSIONS
Marked variation exists in whether a breast core biopsy is performed prior to initial breast surgery, which may represent unnecessary surgery on individual patients. Providing surgeon-specific feedback on guideline compliance may reduce unwarranted variation.
