An electronic medical record reminder is independently associated with improved opportunistic influenza vaccination rates for older inpatients

Background:Influenza vaccination will have added importance this winter given the possibility of further waves of the COVID-19 pandemic. This study examines the impact of an electronic medical record (EMR) reminder on influenza vaccine uptake among eligible hospital inpatients.Methods:We included a convenience sample of 750 adults (median age 77 years) who are eligible for influenza vaccination (> 65 years and/or length of stay >30 days). A live electronic dashboard identified patients eligible for vaccination, prompting reminders sent to the clinical teams via the EMR.Results:The EMR reminder was associated with almost a 50% higher likelihood of vaccination after adjusting for other covariates (odds ratio 1.48 (95% confidence interval 1.00-2.20); p = 0.048).Discussion:Reminders sent to the clinical team via the EMR appear to be an effective means of increasing vaccine uptake and should be considered as part of this year's drive to vaccinate eligible patients in hospital.
