Abstract P1-09-11: Can patient navigation help overcome barriers to breast cancer treatment in patients with health care disparities?

Abstract

Abstract Background: Patient navigation has been demonstrated to aid in adherence to breast cancer screening initiatives. Fewer studies have documented benefit for patients undergoing treatment, and especially among those with barriers to care. Cancer health disparities affecting low-income and minority patients are well documented. Causes of poor outcomes include treatment delays coupled with social and financial barriers. This report examines the impact of patient navigation on adherence to prescribed cancer treatment, including in patients receiving treatment in adjuvant and metastatic breast cancer settings. Methods: This Patient Navigation project (supported by an Avon Foundation grant) was initiated at our public safety net hospital to test whether there was sufficient benefit to warrant a larger randomized trial. Health care coverage included 58% Medicaid, 7% uninsured or undocumented. This study was conducted over a 4 month period with new medical oncology practice patients. Those deemed to be at high risk for non-adherence received navigated care. Navigator duties included care coordination, appointment reminders, patient education materials, translation services, and transportation arrangement. Data collected prospectively included patient characteristics, cancer type, time from referral to first RT, and compliance with visits; this was compared with usual care controls during the 4 month period. Results: Patient Navigation Program patient characteristics: N = 52 patients (42% breast cancer, 12% prostate cancer, 10% lung cancer and 36% with other cancers). Mean age = 55; 48% Black, 38% Hispanic, 8% Asian, 6% White. The table below gives the results of percentage of adherence to visits (and time to first RT) for all patients in the study receiving navigated care, for just the patients with breast cancer receiving navigated care, and for the usual care control (no navigated care).

No impact on time to first RT was shown. These results document that a Patient Navigation Program can help overcome barriers to good cancer care.
