Taste Alterations Study

BACKGROUND/RATIONALE: Chemotherapy-induced taste alteration (TA) is a common problem for cancer patients with reported prevalence ranging from 35% to 69%. TA systems are associated with decreased dietary intake, malnutrition, and decreased quality of life with no known treatment. Researchers have demonstrated that breast cancer patients were able to control TA with the use of patient self-monitoring and self-management strategies, but these strategies are relatively untested. Research is needed to confirm the effectiveness of this nurse-led intervention when delivered by clinicians with a heterogeneous patient population. PURPOSE To increase our understanding of the patient experience with TA during chemotherapy and test if adding steps to assess and lessen taste alterations works better than usual care. The infusion clinics will be randomly assigned and trained to provide usual care or usual care with added strategies. Patients receive care method based on clinic assignment (control/treatment). The study does not involve the use of experimental drugs, devices, or procedure. METHOD: This prospective cluster randomized controlled trial (RCT) is designed to enroll consenting adult cancer patients (n=50/clinic x 8 clinics; N=400) who initiate chemotherapy to evaluate the effect of a nurse-led intervention to engage patients in assessing and self-managing taste alterations (TA) during the first (4) chemotherapy cycles with six months. INTERVENTION: The nurse-led intervention involves using a single item TA assessment question and an intervention tracking process to evaluate change in outcomes for both groups. The intervention involves using a more extensive valid/reliable assessment tool (Chemotherapy-induced Taste Alterations Scale (CiTAS) teaching the patient to use the findings and the evidence-based Patient Education sheet to select assessment-driven interventions to manage TA symptoms. OUTCOMES: TA severity (single item and scale); Interventions Used; Patient-reported Effect; Dietary Intake, and BMI. This study will advance the science by designing and testing the effectiveness of a nurse-led intervention to support infusion clinic patients in TA self-monitoring and management for a heterogenous patient populations beyond breast cancer.
