Abstract

Background and Objective

Formative research studies can inform stated-preference instrument development to quantify the importance of various attributes of healthcare treatments. The objective of this study was to elicit from patients with chronic obstructive pulmonary disease the prioritization of an established set of patient-informed value elements.

Methods

Using an iterative mixed-methods study design, we engaged individuals living with chronic obstructive pulmonary disease in Phase 1 value element elicitation and Phase 2 language refinement. Study participants were recruited from March to July 2019. Four guided activities, administered in an online instrument, elicited individual preferences for 40 disease-agnostic value elements that were aligned with treatment, outcomes, or care process. Responses from the guided activities were summarized and then presented to a patient advocate and additional patient participants for further refinement of the value elements and the phrasing.

Results

Twenty-three participants, 18 male and five female, mean age of 66 years (standard deviation = 7) were enrolled in Phase 1. Participant responses informed the selection of eight elements as the key candidates for the Phase 2 language refinement: Side Effects, New Therapeutic Option, Available Treatment, Appropriateness of Care, Predictable Healthcare Needs, Physical Activities: Endurance and Symptom Control, and Explanation of Treatment. With feedback from a patient advocate and additional patient participants, elements were refined, rephrased, or modified and this list was narrowed to six value elements (Side Effects, New Therapeutic Option, Willingness to Pay, Physical Activities, Explanation of Treatment, and Access to Care) to serve as attributes in a conceptual framework for a future quantitative stated-preference instrument.

Conclusions

This patient-engaged formative work identified patients with chronic obstructive pulmonary disease key attributes of value-based decision making that underpin benefit-risk trade-offs between physical endurance, treatment side effects, care access, and cost. This study illustrates an iterative process for eliciting and refining a comprehensive list of value elements, resulting in a subgroup of elements important to a specific patient population.
