Tailored Intervention Protocol for Oral Chemotherapy Adherence

While cancer patients express a preference for oral medications, compliance to these
medications varies. Patients who successfully adhere to chemotherapy regimens have a greater
chance of non-recurrence and long-term quality of life. Thus, helping patients tolerate oral
chemotherapy regimens is critical to their survival. The aims of this study are to 1) test
the effectiveness of a tailored protocol to promote adherence to oral chemotherapeutic
agents in adults receiving treatment for cancer, 2) examine adherence to oral
chemotherapeutic agents over time, and 3) examine the effects of age, gender, caregiver
availability, personal involvement in health care, and depression on adherence rates to oral
chemotherapeutic agents.

The tailored adherence protocol is based on the self-regulatory model of adherence. The
intervention identifies patient knowledge, behavioral skills, and affective support and
tailors adherence strategies or overcomes barriers in each of these three categories. A
randomized clinical trial will examine the adherence rates in a 150 adults started on a new
oral chemotherapeutic agent. A control group will receive standard chemotherapy education.
Participants in the experimental group will receive the standard education, an assessment
and the tailored intervention developed by an advanced practice nurse. The intervention will
be administered via telephone calls over six months. Patient adherence rates will be
measured in both groups at 2, 4 and 6 months using self report, symptom profiles, and
pharmacy fill rates. To determine the effectiveness of the adherence protocol, we will use
Generalized Estimating Equations (with SAS), which provide a unified approach to
longitudinal modeling techniques for normally and non-normally distributed outcome
variables.
