Use of navigators to identify breast cancer patients for genetic counseling and testing: A quality improvement project

ABSTRACT

The value of genetic counseling and testing to cancer prevention, early detection, and treatment options to ensure optimal outcomes is widely acknowledged by providers, payers and patients. However, many individuals who should receive genetic counseling are never offered this service. All patients with early onset (<=age 45), triple negative (<=60) and metastatic HER2 negative breast cancer should be offered genetic counseling and testing (GC/GT) per National Comprehensive Cancer Network guidelines. A quality improvement project to actively identify and offer genetic counseling to all women with early onset, triple negative and metastatic breast cancer was implemented. Baseline information on the number of early onset (<=45), triple negative and metastatic HER2 negative breast cancers diagnosed January 2018-June 2019 was collected and cross-referenced with the Cancer Genetics Risk Assessment patient database and the electronic health record (EHR) to see how many had GC/GT in our department or the breast surgeons' office. We developed questions for an electronic screening tool used by the navigation team when meeting with patients for the first time, screening for personal or family history criteria that would flag patients at increased risk for hereditary cancer. If any questions were flagged, the patient was asked by the navigator if they would be interested in a genetic counseling appointment to consider genetic Stesting. Training was provided to the navigation team so that they could answer basic questions, biweekly meetings were set up to discuss patients, and a flier and informational videos were made available to patients who wanted more information about GC/GT. If a patient was agreeable to genetic counseling, an automated email was triggered to the genetics team, who contacted the patient for an appointment. A standing order was obtained from willing breast surgeons and oncologists within our network to streamline the referral process. In the 18-month baseline period, there were 126 patients diagnosed with early onset, 36 with triple negative <=60 and 30 with metastatic HER2 negative breast cancer. Of these, 57.1% of early onset, 66.7% triple negative and 3.3% of those with metastatic breast cancer had documentation of GC/GT. A paper screening tool was implemented in July 2019 with implementation of an electronic version in November 2019. In the 18-month intervention period, there were 100 patients diagnosed with early onset, 39 with triple negative and 22 patients with metastatic breast cancer. Of these, 86% of early onset, 87.2% of triple negative and 31.8% of metastatic breast cancer patients had documented GC/GT.A limitation of this project is that some patients leave the system to be treated elsewhere after diagnosis and some may have been tested in their private practitioner's office that does not connect with our EHR. Additionally, some may have been offered GC/GT but declined or were unwilling/unable to complete an appointment. Finally, the pandemic likely had an impact on this project, since fewer women were undergoing mammography screening due to COVID-19 restrictions, resulting in fewer diagnoses of breast cancer. By leveraging the navigation team's interaction with breast cancer patients, we were able to improve identification and referral of more patients with early onset, triple negative <=60 and metastatic HER2 negative breast cancer for GC/GT. One barrier to genetic counseling that has been previously identified is a lack of physician referral. Active engagement with a breast navigator can circumvent this barrier. De-identified aggregate data from this quality improvement project was shared with the Association for Community Cancer Centers as part of a larger project, supported by a grant from Pfizer.
