Perceptions of injectable therapies with cardiovascular benefit: an ACNAP survey of healthcare professionals to explore facilitators and barriers

Aims Injectable medicines are increasingly used to manage risk factors for cardiovascular (CV) events, such as dyslipidaemia and diabetes. These include proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists. Little is known about perceptions of injectable therapies among CV healthcare professionals (HCPs). This study explores their views to identify relevant facilitators and barriers to the use of injectables with CV benefit. Methods and results A 22-question survey was distributed internationally via online channels. In total, 192 anonymous responses were received (43.7% physicians, 32.6% nurses, 16.8% pharmacists, 6.8% others). Among respondents with experience of these medicines, 69.1% had used an injectable PCSK9 inhibitor and 67.0% had used an injectable GLP-1 receptor agonist. Commonly raised issues were resource problems (36.5%), lack of knowledge among colleagues (32.3%), paperwork (32.3%), and lack of patient knowledge (28.1%). Key barriers respondents felt made patients decline these treatments were fear of injection (56.6%), lack of awareness or education (26.4%), and administration issues (15.1%); potential reasons for discontinuation included side effects (46.4%), perceived lack of benefit (28.6%), and local reactions (21.4%). The main topics around injectables requiring further support included managing non-adherent patients (16.2%), troubleshooting with patients (16.2%), and educating colleagues about injectables (12.2%). Preferred educational methods to support HCPs were face-to-face training (43.5%) and online learning (26.1%); favoured formats were based on role playing and case studies. Conclusion Healthcare professionals highlighted various potential barriers to initiation, continuation, and adherence with injectable therapies in CV medicine. Although some require healthcare system changes, many could be addressed through simple measures based primarily on enhanced training and support for patients and HCPs.
