Development of the oncology opportunity cost assessment tool.

Abstract

e13502 Background: While awareness of direct patient-level costs of cancer care are growing, less is known about the patient-level opportunity cost of care. Opportunity costs of care may include time spent seeking care, lost wages, lost leisure time, and other indirect costs associated with seeking care. Despite acknowledgment of the importance of considering patient opportunity costs in care treatment decisions, assessment of opportunity costs experienced by individual patients or caregivers is not routinely performed by healthcare providers in general, or oncology providers in particular. The purpose of this work was to develop an instrument, the Oncology Opportunity Cost Assessment Tool (OOCAT), to evaluate patient opportunity cost of seeking oncology care. Methods: Survey development was an iterative process with multiple rounds of stakeholder engagement. First the research team developed a list of potential opportunity cost themes informed by their own experiences. Next, we met with an established patient advisory group within the cancer center to expand this list of themes. We then conducted focus groups with patients and caregivers to explore in further depth their logistical and financial considerations related to seeking care. Findings were used to further expand the list of opportunity cost themes, with this list reviewed in real time with the focus group participants to ensure perspectives were appropriately captured. We then generated a set of survey items to represent each of the themes listed. We generated two items to represent each unique theme. The first item of the instrument sought to quantify the opportunity cost of the theme (e.g. time spent parking); the second component ascertained the patient-perceived importance of the theme using a 7-point Likert scale. Upon drafting of the initial OOCAT, we performed cognitive interviews with a random sampling of patients in order to ensure content validity and clarity of instrument items. Results: We completed 4 virtual focus groups with a total of 23 participants (17 patients and 6 caregivers) followed by cognitive interviews with 13 patients. The resulting OOCAT consists of 17 items that examine time requirements, financial implications, and logistical and quality of life challenges for both patients and caregivers associated seeking oncology care. Conclusions: The OOCAT is a 17-item instrument designed to quantify patient-level opportunity costs of seeking oncology care. Further studies work is needed to validate the OOCAT survey and assess the impact of incorporating quantified assessment of opportunity cost into decision regarding when and where to seek oncology care.
