Supplementary Material for: Physician perceptions of medication prescribing in heart failure: a scoping review.

Introduction: The swift uptake of new medications into clinical practice has many benefits, however slow uptake has been seen previously with other guideline-directed medical therapies (GDMT) in heart failure (HF). Sodium glucose co-transporter 2 inhibitors are a novel therapy in HF proven to be efficacious and will have beneficial clinical outcomes if prescribed. Understanding physician perspectives on prescribing GDMT in HF can help target strategies to bridge the gap between guidelines and practice.

Methods: The study followed the PRISMA guide for scoping reviews and the JBI Manual for scoping reviews. A search was conducted using EMBASE, Medline and PubMed databases in April 2024. Studies included were those using qualitative methods to assess physician perspectives towards prescribing any HF medication. Common themes were identified through thematic synthesis following the methods from Cochrane Training and using software MAXQDA Analysis Pro.

Results: 708 studies were found in the search, with 23 full studies included. The most pertinent barriers identified were concern for medication adverse effects, unclear role responsibilities between physicians of different specialties, patient comorbidities and unwillingness to alter therapies of stable patients. The most identified enablers included awareness of efficacy, influence from colleagues and the use of multi-media approaches for information dissemination. Perceptions were also found to change over time and vary among prescriber groups.

Conclusions: Physicians perceive common barriers and enablers of prescribing GDMT in HF, despite differences in prescriber groups and time periods. The identified barriers and enablers may be targeted to improve implementation of GDMT into clinical practice.
