Kaiser announced in EurekAlert! that hospitalized patients who received the flu vaccine had no increased risk of outpatient visits or hospital readmission within seven days of discharge, according to a Kaiser Permanente study published today in Mayo Clinic Proceedings. The study also showed that vaccinating hospital patients did not increase the risk of fever or rates of laboratory evaluations for infection. It also showed that the vast majority of patients who were not vaccinated during their hospital stay remained unvaccinated for the full flu season.
- 71 percent of patients vaccinated during their hospital stay were vaccinated on the day of discharge.
- 74 percent of those who miss the opportunity to vaccinate before or during hospitalization remained unvaccinated throughout the season.
- No increased risk of hospital readmissions, outpatient visits, fever, or clinical evaluations for infection among patients who received the flu vaccine during their hospital stay.
