Abstract
Patients with breast cancer spend significant time1, effort, and financial resources2 to combat the disease for years after their diagnosis. The large volume of healthcare tasks can cause patients to become overburdened, leading to reduced adherence with care plans and worse outcomes3. On the other hand, certain patient characteristics such as physical resilience, financial well-being, and supportive family environments increase patients' capacity to manage care4. Assessing treatment burden and capacity when prescribing care has been applied to populations such as diabetes patients5. We are investigating this paradigm in treatment of patients with breast cancer. The goal of this preliminary study is to identify significant factors that contribute to treatment burden, capacity to manage care, and outcomes of overburden for patients with breast cancer.
Examples of treatment burden, capacity to manage care, and outcomes of overburden in patients with breast cancerTreatment burdenCapacity to manage careOutcomes of overburdenTraveling long distances for careAccess to reliable transportationReduced spending on food, utilities, or other necessitiesPaying for child care during chemotherapyFlexibility in informal caregivers' schedulesMissed appointment with medical oncologistRemembering to take medications with mealsMedical understanding or knowledgeWorse than expected side effectsReporting adverse eventsProficiency with mobile deviceTrip to emergency room
Through literature review, interviews with survivors, and expert panels of navigators and providers, we will develop a survey instrument given to patients at the time of diagnosis. The survey will assess patient capacity and help providers give treatment options based on attributes of the patient. Additionally, we will attempt to correlate survey results with treatment burden measures derived from electronic health record data at a population level1. With treatment personalized for patient capacity, patients should be better able to adhere to care plans leading to improved quality of life during treatment and beyond.
