Effects of a Patient Question Prompt List on Question Asking and Self-Efficacy During Outpatient Palliative Care Appointments

Context: Question prompt lists (QPLs) promote participation during medical appointments, including in the context of serious illness care. However, no studies have used parameters of a theoretical framework to examine the effects of QPL use in outpatient palliative care. Objectives: The current pilot randomized controlled trial evaluated use of a 25-question QPL during initial outpatient palliative care appointments. We applied tenets of Self-Efficacy Theory to investigate how use of a QPL affected appointment participation and perceived self-efficacy. Methods: Participants were patients and care partners attending the patient's first palliative care appointment. Participants either received a QPL before the appointment (n = 29 appointments) or usual care (n = 30 appointments). Audio recordings of appointments were coded for total questions asked. Participants reported perceived self-efficacy in question asking pre- and postappointment. Analysis of variance was used to compare appointment participation between study conditions, and a linear mixed effects model was used to compare changes in ratings of perceived self-efficacy. Results: Participants who received the QPL did not ask significantly more questions compared to participants in usual-care appointments. There was a main effect of time on self-efficacy in question asking, such that self-efficacy increased from pre- to postappointment, but there was no effect of the intervention. Conclusion: Despite their promise in previous studies, results of the current study suggest that QPLs may lack potency to shift patient and care partner question asking in palliative care appointments, and that other mechanisms outlined in Self-Efficacy Theory may characterize the relation between question asking and self-efficacy.
