Abstract

Background

Many factors influence whether breast cancer patients undergo reconstruction after mastectomy. We sought to determine the patterns of care and variables associated with the use of breast reconstruction in Southern California.

Materials and Methods

Postmastectomy reconstruction rates were determined from the California Office of Statewide Health Planning and Development (OSHPD) inpatient database from 2003 to 2007. International Classification of Disease-9 codes were used to identify patients undergoing reconstruction after mastectomy. Changes in reconstruction rates were examined by calendar year, age, race, type of insurance, and type of hospital using a chi-square test. Univariate and multivariate odds ratios (OR) with 95% confidence intervals (95% CI) were estimated for relative odds of immediate reconstruction versus mastectomy only.

Results

In multivariate analysis, calendar year, age, race, type of insurance, and type of hospital were statistically significantly associated with use of reconstruction. The proportion of patients undergoing reconstruction rose from 24.8% in 2003 to 29.2% in 2007. Patients with private insurance were 10 times more likely to undergo reconstruction than patients with Medi-Cal insurance (OR 9.95, 95% CI 8.46–11.70). African American patients were less likely (OR 0.58, 95% CI 0.46–0.73) and Asian patients one-third as likely (OR 0.37, 95% CI 0.29–0.47) to undergo reconstruction as Caucasians patients Most reconstructive procedures were performed at teaching hospitals and designated cancer centers.

Conclusions

Although the rate of postmastectomy reconstruction is increasing, only a minority of patients undergo reconstruction. Age, race, type of insurance, and type of hospital appear to be significant factors limiting the use of reconstruction.
