Evaluating Interventions to Increase Influenza Vaccination Rates among Pediatric Inpatients.

Abstract

Introduction:Hospitalization provides an ideal opportunity for influenza vaccination, and strategies can enhance existing tools within the electronic medical record (EMR). The objectives of the study were to introduce and evaluate the effectiveness of provider and family-directed interventions to increase influenza vaccination ordering among inpatients.Methods:We conducted a quality improvement initiative for children aged older than 6 months on medical inpatient teams at a large pediatric tertiary care hospital from September 2014 to March 2015, comprising 2 intervention groups (provider reminders and family education) and 1 control group for comparison, using EMR prompts alone. The provider reminder interventions comprised weekly e-mails indicating inpatient immunization status; vaccination reports; and visual reminders. The family education group intervention consisted of handouts regarding the benefits and safety of influenza vaccination. We measured vaccine ordering rates for each group among eligible children and overall vaccination rates. Data were analyzed using Statistical Process Control Charts and Chi-square tests.Results:Among 2,552 patients aged older than 6 months hospitalized during the study period, 1,657 were unimmunized. During the intervention period, the provider group ordered 213/409 (52%) influenza vaccines, the family education group ordered 138/460 (30%) and the control group ordered 71/279 (25%) (P < 0.0001). The provider group had higher influenza immunization status than the control group (61% versus 53%; P = 0.0017). Exposure to the intervention did not impact the length of stay/discharge time.Conclusions:Provider reminders including e-mails, visual reminders, and vaccination reports are effective ways of increasing inpatient influenza vaccination rates and are more effective than family education, or EMR prompts alone.
