Evaluation of vaccination coverage in heart failure patients in a tertiary center

Despite current recommendation, vaccination coverage (VC) for patients with heart failure (HF) remains far too limited.

To evaluate the VC of HF patients followed in our hospital center and investigate the barriers to vaccination and the ways to address them.

This was a cross-sectional monocentric descriptive study conducted between December 2019 and January 2021 at the University Hospital of Montpellier, France. Patients with HF history hospitalized in cardiology unit (CU) and patients in a HF telemonitoring program (TP) were included. An interview was conducted by a pharmacist to find out the patient's vaccination status against influenza and pneumococcus. For non-vaccinated patients, opinion and willingness to be vaccinated were also obtained.

Data from 335 patients were collected (185 in CU, 150 in TP). The mean age was 69.3 years and the proportion of males was 72%. About 65% were vaccinated against influenza in the last year (60% in CU, 72% in TP, p = 0.022) and 22% were up to date with pneumococcal vaccination (11% in CU, 35% in TP, p < 0.001). Among patients not vaccinated, 17% refused vaccination. Among unvaccinated patients who consider vaccination, 69% wanted to be vaccinated by their general practitioner (GP).

The VC of HF patients remains insufficient. Patients in TP are more vaccinated than patients in CU, which could involve better management. The low rate of vaccinated patients is mainly explained by a lack of awareness. The medical team, including the clinical pharmacist by his dedicated time during medication reconciliation may play a major role in the management of hospitalized patients as well as GP's as local actors.
