Study Summary

In this study, we will test the feasibility of N-of-1 trials for deprescribing beta-blockers in patients with Heart Failure with Preserved Ejection Fraction. To achieve this objective we will conduct 16 4-period N-of-1 trials (on vs. off) and subsequently interview participants to better understand feasibility and pragmatism. The N-of-1 trials will be iteratively refined in real-time based on this feedback.

Primary Outcome

Qualitative interviews were conducted to assess the feasibility and acceptability of deprescribing N-of-1 trials and participant experiences. Directed content analysis methods were used to develop relevant categories and themes from interview transcript data. Transcripts were coded and analyzed by two team members, consulting additional members to establish consensus where needed. Inter-rater reliability between coders was established.
