About
Improving Adherence to Oral Cancer Agents and Self Care of Symptoms Using an IVR The goals of this study are to improve adherence to oral chemotherapeutic medications and self-management of symptoms among cancer patients. More than 40 oral agents currently are on the market with projections that in three years 30% of the cancer treatment agents will be delivered in oral form. As a result, patients must assume responsibility for taking medications and self-management of associated side effects.
This longitudinal randomized trial tests and compares 'two strategies' for improving patient adherence to their oral cancer medication prescriptions to standard care. Both strategies incorporate symptom management support using an interactive voice response system (IVR) for symptom assessment and a printed evidence-based Medication Management and Symptom Management Toolkit (Toolkit) with helpful strategies and information for symptom management.
We will collaborate with NCI Comprehensive Cancer Centers to recruit patients into this study. Recruiters will identify patients as they are prescribed oral cancer medications, present the study to the patient, and ask them to consent to be part of the study.
Study Aims Following are the Aims of the study.
- Cancer patients assigned to the intervention will have greater adherence to their prescribed regimen: a) at week 4 (immediate effect), and b) at weeks 8 and 12 (sustained effect).
- When compared with patients receiving weekly assessments only, patients receiving weekly assessments plus daily adherence reminders and printed symptom management strategies for 4 weeks will report: lower symptom severity during weeks 2-4 that will be sustained at weeks 5-8, and at 12 weeks.
Two exploratory aims are assessed:
- To test how patient characteristics (age, sex, depression), dose variation, symptom severity, and concurrent infusion therapy moderate the impact of the novel intervention on adherence at 4, 8, and 12 weeks.
- To test the impact of the novel intervention on dose alterations, emergency department visits and hospital admissions over the 12 weeks in order to support the translation of this system into oncology practices.
Full description
Design and Methods A unique feature of this study is that assessments, reminders, and symptom management strategies will be delivered by an Interactive Voice Response system (IVR). This system has been tested in a previous trial and in a pilot study of medication adherence; it received high satisfaction ratings from patients.
All patients will complete intake (baseline), 4 week, 8 week, and 12 week interviews for symptom severity, depression, beliefs about oral agents, self-efficacy, and pill count. Following the intake interview a computerized procedure will randomize patients to one of two groups: experimental and control. Patients in both arms will receive 12 weekly assessments of adherence to their oral cancer medications and symptom severity delivered by the IVR.
In addition, patients in the experimental group will receive daily reminder calls for 4 weeks delivered by the IVR. At the end of week 4 patients will be offered the option to reduce calls to every other day, or continue with daily reminders for weeks 5-8. Reminder calls will be tailored to the cycle of each medication. Daily reminder calls include a question to determine if medication changes have occurred. If this occurs, reminder calls are stopped and/or adjusted to the revised prescription. Patients in the experimental group will be mailed a Toolkit. Patients who report symptoms above designated thresholds during a weekly assessment call will be referred to the Toolkit to assist with self-management.
The control group will not receive IVR reminder calls during the first 8 weeks. Control group patients, who report difficulty taking their cancer medications as prescribed, will be randomized following the 8 week interview to either receive 4 weeks of daily IVR reminder calls during weeks 9-12, or to continue in the control group. Patients randomized to receive daily IVR reminder calls will receive a Toolkit following randomization (and if during their weekly assessment calls they report symptoms above designated thresholds they will be referred to the Toolkit to assist with self-management). Patients randomized to continue in the control group will receive a Toolkit upon completion of the 12 week interview.
Medical records will be audited for oral cancer medication changes during the study period as well as adverse toxic events noted, and scripts written.
Implications & Impact This research will identify and explore the factors (symptom severity, medication complexity, patient characteristics) affecting adherence to oral cancer medications and how symptom management might improve levels of adherence. This will allow patients to engage in their care and potentially transform the safety and quality of cancer care for patients on oral cancer medications.
