227 Background: Since 2011, 50% of HNCA patients receiving concurrent chemoradiation with Cisplatin (CIS/XRT) have not been able to complete their therapy per protocol (dose over time interval) leading to suboptimal therapy. Based on historical data, the non-completion rate for patients HNCA receiving radiation/ high dose Cisplatin was 15%. We aim to improve this in our patients. Methods: A chart review of patients on CIS/XRT conducted and, using a Pareto Chart, the data indicated Acute Kidney Iinjury as the major cause for failure of completion. Using methodology from ASCO’s Quality Training Program, a process map for patients on treatment was created and an Ishikawa diagram (cause and effect) assisted in pinpointing breaks in processes. A telephone survey of surviving patients further clarified inadequacies. Using the Plan, Do, Study, Act (PDSA) improvement cycle, inadequacies were identified. Results: Chart review showed that significant side effects from treatment began around the 2nd cycle of Cisplatin in spite of adequate IV hydration following chemotherapy. Inadequate documentation of dietary and speech pathology consultations, patient weight and serum creatinine levels during treatment were noted. Patients reported minimal PEG tube education and infrequent use of PEG tube for hydration. Analysis of post treatment weight and creatinine level revealed a significant change in creatinine clearance. Checking daily weights, speech pathology and dietary consult prior to initiation of therapy, added hydration instructions to EPIC PEG tube instruction sheet, and nurse practitioner education and follow-up in symptom management clinic were part of the PDSA cycle interventions. If 2lb. weight loss, patients were brought in for repeat lab and IV hydration. Conclusions: Patients with advanced head and neck cancer are frail and subject to acute toxicity from chemotherapy. Change in Creatinine Clearance is a sensitive measure of renal damage/likely predictor of non-completion. Post-intervention patients had fewer unplanned admissions leading to lower costs. PDSA helped identify inadequacies in our education and monitoring processes. More post intervention data are needed to determine if true improvement in patient outcomes exist.
