Background: The treatment of ALL involves complex chemotherapy regimens that are difficult to deliver to underserved populations. Lyndon B. Johnson General Hospital (LBJGH) provides care to uninsured and underinsured patients in Harris County, the third largest county in the United States. Our goal is to achieve 80% adherence to National Comprehensive Cancer Network guidelines in the care of newly diagnosed ALL patients at LBJGH. Methods: The charts of 14 patients with newly diagnosed ALL were reviewed. Demographics, initial work-up (e.g., bone marrow biopsy and aspirate), type of treatment, adherence to scheduled treatment, use of supportive medications, outpatient follow-up, stem cell transplant referral and quality of provider documentation were collected. Areas of potential improvement were then identified using provider focus groups and Ishikowa Diagram. The project was approved by the MD Anderson Quality Improvement Assessment Board. Results: 12/14 patients were evaluable, having received their full course of care at LBJGH. The median age was 35, 9/12 (75%) were female and 9/12 (75%) were Hispanic. 6/11 (55%) cases expressed CD20 (CD20+) and 3/11 (27%) were Philadelphia chromosome positive (Ph+). All 12 patients received induction and consolidation therapy with the HyperCVAD regimen (cyclophosphamide/vincristine/doxorubicin/dexamethasone alternating with high-dose methotrexate/cytarabine). Bone marrow biopsy at time of diagnosis, use of a tyrosine kinase inhibitor for Ph+ ALL, and use of supportive medications occurred >80% of the time. Administration of outpatient chemotherapy, use of rituximab for CD20+ ALL, outpatient lab follow-up, intrathecal chemotherapy and appropriate referral for allogeneic transplant occurred 50-80% of the time. Provider documentation was appropriate <50% of the time. Conclusions: Based on these findings, we established a standard algorithm of care for ALL patients at LBJGH, enhanced provider education through the design and distribution of teaching tools, created a checklist to facilitate handoffs between providers and established expectations for documentation. In the future, we would also like to add a patient navigator to further improve coordination of care.
