The therapeutic outcome of cancer treatment for patients taking oral chemotherapy agents depends heavily on adherence to the oral agent regimen. Yet recent research indicated that patients miss one-third of oral chemotherapy agent doses. With more than 50 oral anti-cancer agents on the market, it is projected that within 3 years, 25% of cancer treatment will be delivered in pill form. In this new treatment paradigm, care is moved from the clinics to home settings. This means that patients are seen less frequently by oncologists and greater responsibility is placed on the patients. Complicating this further, 75% of those with cancer also have comorbid conditions that require them to perform other self-care management (SCM) responsibilities. In addition, many have low self-efficacy, which may interfere with their ability to adhere to the oral agent. The therapeutic outcome for patients taking oral agents depends heavily on engaging patients to adhere to the regimen. Thus, a critical need exists to test novel interventions that promote adherence in patients taking oral chemotherapy agents.
