Abstract
11125 Background: ASCO guidelines recommend screening all patients for hepatitis B virus (HBV) before initiation of cancer therapy. Comprehensive screening for HBV includes measuring HBV surface antigen (HBsAg), HBV core antibody (anti-HBc), and antibody to HBV surface antigen (anti-HBs). ASCO also recommends hepatitis C virus (HCV) screening in patients with cancer. Cancer patients receiving cancer therapy represent a vulnerable population and reactivation of undetected hepatitis virus can lead to devastating consequences such as liver failure and death. At MD Anderson Cancer Center, rates of hepatitis screening for all cancer patients has been historically low. For example, rates are around 29% for HBV screening in patients receiving cancer therapy in 2019-2021. The aim of this quality improvement study is to increase rates of HBV and HCV screening in early breast cancer patients in the Breast Medical Oncology clinic at MD Anderson before undergoing cancer therapy to at least 50%. Methods: Quality improvement measures were implemented by 1) creation of an order panel in the electronic medical record (EMR) which contains all tests needed for comprehensive HBV and HCV screening (HBsAg, anti-HBc, HBsAb, and anti-HCV), and 2) an educational session to providers in the Breast Medical Oncology clinics. Data was collected for patients seen at MD Anderson initiating cancer therapy (start of cycle 1) between April 1, 2023 until September 30th, 2023. Inclusion criteria were early breast cancer patients (Stage I-III) and receiving chemotherapy at MD Anderson. Exclusion criteria were Stage IV disease, or those receiving chemotherapy at an outside institution. Results: A total of 340 patients were screened, and 219 were determined to meet inclusion criteria for data extraction. In total, 105 patients (48%) received comprehensive HBV screening, with 137 (63%) receiving at least one HBV test. A total of 122 (56%) patients were screened for HCV. Combining data for both HBV and HCV, 88 (40%) received both comprehensive HBV and HCV screening (HBsAg, anti-HBc, anti-HBs, anti-HCV). A majority of patients (91% for HBV and 93% for HCV) were screened prior to cycle 1 of cancer therapy. The EMR order panel was utilized in 51 (23%) of patients. Anti-HBc was positive in 8 of those tested, and HBsAg was positive in 1 patient. No patients tested positive for HCV. Conclusions: Screening rates for HBV and HCV individually were near or exceeded our goal, however rates of combined HBV and HCV screening were lower. Going forward, additional education to providers as well as increased awareness of the available order panel will be needed to ensure we are comprehensively screening for both HBV and HCV in our patients.
