Complicated breast cancer-related lymphedema: evaluating health care resource utilization and associated costs of management.

BACKGROUND

Lymphedema can become a disabling condition necessitating inpatient care. This study aimed to estimate complicated lymphedema incidence after breast cancer surgery and calculate associated hospital resource utilization.

METHODS

We identified adult women undergoing lumpectomy and/or mastectomy with axillary lymph node surgery between 2006 and 2012 using 5-state inpatient databases. Patients were grouped according to the development of complicated lymphedema. The primary outcomes were all-cause hospitalizations and health care charges within 2 years of surgery. Multivariate regression models were used to compare outcomes.

RESULTS

Of 56,075 women included, 2.3% had at least 1 hospital admission for complicated lymphedema within 2 years of surgery. Despite confounder adjustment, women with complicated lymphedema experienced 5 fold more all-cause (incidence rate ratio = 5.02, 95% confidence interval: 4.76 to 5.29) admissions compared with women without lymphedema. This resulted in substantially higher health care charges ($58,088 vs $31,819 per patient, P < .001). Although axillary dissection and certain comorbidities were associated with complicated lymphedema, breast reconstruction appeared unrelated.

CONCLUSIONS

Complicated lymphedema develops in a quantifiable number of patients. The health care burden of lymphedema underscored here mandates further investigation into targeted, anticipatory management strategies for breast cancer-related lymphedema.
