Insights
Patient reminders increase influenza vaccination rates in children. However, less than a quarter of parents reported receiving reminders, highlighting a need to improve this outreach for better child vaccination coverage.
Area of Science:
- Public Health
- Epidemiology
- Vaccinology
Background:
- Patient reminders are a recommended strategy to enhance vaccination rates.
- Understanding the reach and impact of these reminders is crucial for public health initiatives.
- This study investigates patient reminder receipt and its association with influenza vaccination in children.
Purpose of the Study:
- To determine the percentage of children (6 months-17 years) whose parents received influenza vaccination reminders.
- To assess influenza vaccination coverage in relation to patient reminder receipt.
- To identify demographic and survey-related factors associated with receiving patient reminders.
Main Methods:
- Analysis of National Immunization Survey-Flu (NIS-Flu) data from the 2013-14 influenza season.
- Utilized Wald chi-square and pairwise t-tests to examine associations between reminders and demographics.
- Employed multivariable logistic regression to identify independent predictors of reminder receipt.
Main Results:
- Approximately 22% of children's parents reported receiving an influenza vaccination reminder.
- Children who received a reminder had significantly higher vaccination coverage (73.7%) compared to those who did not (55.5%).
- Reminder receipt was more common for younger children (6-23 months), Black children, and when surveys were completed in English.
Conclusions:
- Patient reminders are linked to increased influenza vaccination likelihood in children.
- Nationwide, less than 25% of parents report receiving reminders, indicating a gap in current outreach.
- Enhancing patient reminder systems for parents could significantly improve childhood influenza vaccination coverage.
Background:
Patient reminders are recommended to increase vaccination rates. The objectives of this study were to estimate the percentage of children 6 months-17 years for whom a patient reminder for influenza vaccination was received by a child's parent or guardian, estimate influenza vaccination coverage by receipt of a patient reminder, and identify factors associated with receipt of a patient reminder.
Methods:
National Immunization Survey-Flu (NIS-Flu) data for the 2013-14 influenza season were analyzed. Tests of association between patient reminders and demographic characteristics were conducted using Wald chi-square tests and pairwise comparison t-tests. Multivariable logistic regression was used to determine variables independently associated with receiving a patient reminder.
Results:
Approximately 22% of children had a parent or guardian report receiving a patient reminder for influenza vaccination for their child, ranging from 12.9% in Idaho to 41.2% in Mississippi. Children with a patient reminder were more likely to be vaccinated compared with children without a patient reminder (73.7% versus 55.5%). In the multivariable model, reminder receipt was higher for children 6-23 months compared with children 13-17 years, black children compared with white children, and children whose parent completed the survey in English compared with children whose parent completed the survey in a language other than English or Spanish.
Conclusions:
Although patient reminders are associated with a higher likelihood of influenza vaccination, nationally, less than one-fourth of children had a parent report receiving one. Despite being based on parental report, with its limitations, this study suggests that increasing the number of parents who receive patient reminders for their children may improve vaccination coverage among children.
