Knowledge, attitudes and practices of health care workers in a cardiology department on influenza vaccination

Abstract

Background: Evidence has accrued that influenza vaccination may be effective in preventing myocardial infarction (MI). However, vaccination rates in both adults and health care workers (HCW) are low, and hospitalisation is often a missed opportunity for vaccination. We hypothesised that knowledge, attitude and practices of health care workers regarding vaccination impacts vaccine uptake in hospitals. The cardiac ward admits high-risk patients, many of whom are indicated for influenza vaccine, especially those caring for patients with acute MI.

Aim: To understand the knowledge, attitudes, and practices of HCW in cardiology ward within a tertiary institution, on influenza vaccination.

Methods: We used focus group discussions with HCW caring for AMI patients in an acute cardiology ward, to explore the knowledge, attitudes, and practices of HCW regarding influenza vaccination for patients under their care. Discussions were recorded, transcribed, and thematically analysed using NVivo software. In addition, participants completed a survey on their knowledge and attitudes towards the uptake of influenza vaccination.

Results: A lack of awareness regarding the associations between influenza, vaccination and cardiovascular health was identified amongst HCW. Participants did not routinely discuss the benefits of influenza vaccination or recommend influenza vaccinations to patients under their care; this may be due to a combination of a lack of awareness, not seeing it as part of their job and workload issues. We also highlighted difficulties in access to vaccination, and concerns of adverse reactions to the vaccine.

Conclusion: There is limited awareness among HCW of the role of influenza on cardiovascular health and the benefits of influenza vaccine in the prevention of cardiovascular events. Improved vaccination of at-risk patients in hospital may need active engagement of HCW. Improving the health literacy of HCW regarding the benefits of vaccination as a preventative strategy may result in better health care outcomes for cardiac patients.
