Cardiology patients are unaware of the benefits of seasonal influenza immunization

Abstract

Seasonal influenza immunization reduces the risk of cardiovascular events. Patients with established cardiovascular disease (CVD) derive a greater benefit than those without, yet up to 50 % do not take up the immunization. Patient perceptions and beliefs are known to inform immunization behaviors, yet the immunization related beliefs of patients with CVD have not been described. ObjectiveTo describe beliefs, perceptions and behaviors regarding influenza immunization in patients with CVD. MethodsWe undertook a cross-sectional, voluntary and anonymous survey of 181 cardiology inpatients and outpatients attending three large hospitals in Victoria. ResultsMedian age was 64, 35.0 % were female and 24.2 % spoke a language other than English at home. Over one-third-(34.5 %) of respondents did not receive the seasonal influenza immunization in the prior year. Only half (54.2 %) of patients agreed that their heart condition placed them at higher risk of complications and serious illness if they contracted influenza. Nearly a quarter of patients (24.0 %) were concerned about side effects while 1 in 10 patients raised cost as a barrier despite being free-of-charge in Australia. If asked to receive the seasonal influenza immunization, 86 % patients would agree if their cardiologist recommended it. ConclusionDespite guideline recommendations, most cardiology patients are uninformed of the cardiovascular benefits of seasonal influenza immunization with many unaware they are at higher risk of influenza-related illness. The vast majority of patients would accept the immunization if recommended by their cardiologist highlighting their important role in improving uptake.
