Background: Unplanned radiation treatment breaks are shown to be related to increased risk of local recurrence, lower survival rates and reduced tumor control rates. Weight loss, along with other side effects, can be a major factor in radiation treatment breaks. This quality improvement project aimed to review weight changes and treatment breaks via retrospective chart review to better understand how to improve the combined nutritional and radiation oncology care of head and neck cancer (HNC) patients.
Methods: Utilizing the Lean Six Sigma Project Management approach to ensure critical components were assessed, this quality improvement project reviewed HNC cases via retrospective chart review that started and/or completed definitive radiation treatment from January 1, 2014 - December 31, 2018. Weights were assessed during the timeframe of treatment and limited to weights obtained within the same unit. Treatment breaks were confirmed via Electronic Medical Records (EMR) systems and defined as one or more missed or cancelled treatments, excluding those missed for nonclinical reasons. Charts were reviewed for documented dysphagia, mucositis, and skin reactions. Information on nutrition visits were assessed.
Results: The incidence of patients who experienced treatment breaks was 47.8%. Patients averaged 5.5 missed treatments. More than half of the patients who experienced treatment breaks had Stage IV disease and 62.5% experienced clinically significant weight loss within their treatment time frame. Approximately 15% of patients were seen within a designated oncology nutrition clinic. Side effects, such as mucositis, dysphagia, and skin reactions, were documented to have contributed to weight changes and treatment breaks.
Conclusion: This project highlighted the multifactorial nature associated with radiotherapy treatment of HNC patients. Based on prior experience with integration of nutrition and radiation oncology services and understanding expected treatment side effects, we recommend that nutrition services are integrated as part of the initial radiation consultation process to proactively approach the known weight loss and nutritionally relevant side effects. It is imperative to integrate medical informatics infrastructure to modernize the process of documenting treatment side effects and outcomes. Continued in-depth review of this data will facilitate us in creating a comprehensive multidisciplinary treatment approach for HNC patients undergoing radiation therapy.
