Improving the immunization coverage of children less than 7 years old in a family practice residency
Insights
Direct mail and telephone reminders effectively increased childhood immunizations in a family practice clinic. However, overall immunization coverage remains low, necessitating further interventions for infants and children.
Area of Science:
- Pediatrics
- Public Health
- Preventive Medicine
Background:
- Assessing the impact of targeted communication strategies on childhood immunization rates.
- Evaluating interventions within a family practice residency clinic setting.
- Addressing challenges in maintaining up-to-date immunization coverage for young children.
Purpose of the Study:
- To determine the effectiveness of mail and telephone reminders in improving immunization coverage for children under 7.
- To compare immunization compliance rates between an intervention group and a control group.
Main Methods:
- A prospective cohort study involving 464 children overdue for immunizations.
- Random assignment to an intervention group (mail and telephone reminders) or a control group (no contact).
- Comparison of immunization status 6 months post-intervention.
Main Results:
- The intervention group received more immunizations (124 vs. 84) and had more children brought up to date (34 vs. 17) compared to the control group.
- Statistically significant improvements in immunization compliance were observed in the intervention group (P < 0.047 for immunizations, P < 0.011 for children up to date).
- Despite intervention success, overall practice immunization coverage remained low (10.6% up to date initially).
Conclusions:
- Mail and telephone reminders are effective tools for increasing childhood immunization compliance.
- Significant barriers, including patient mobility and socioeconomic factors, hinder overall immunization coverage.
- Urgent need for additional strategies to improve immunization rates in vulnerable pediatric populations.
Background:
This prospective cohort study was designed to evaluate the effectiveness of mail and telephone contact with parents as a means to improve the immunization coverage of children less than 7 years old in a family practice residency clinic.
Methods:
Immunization records for 519 children enrolled in an outpatient clinic were reviewed and updated. Children whose immunizations were current (55) were excluded, which left 464 children whose immunizations were more than 1 month behind for their age groups. A random sample of one-half of these children (231) were mailed a postcard listing the immunizations that they required to be up to date. The mailing was followed up with telephone contact, when necessary, to prompt compliance. The other one-half of the children were not contacted and served as the control group. Immunizations provided to the two groups were compared 6 months after the initial mailing.
Results:
Before the initiation of the study, only 10.6 percent of the infants and children in the practice had their immunizations completed or were up to date. There were 124 immunizations given to 49 children in the intervention group compared with 84 immunizations to 33 children in the control (P < 0.047). Thirty-four children were brought up to date in the control group compared with 17 in the intervention cohort (P < 0.011).
Conclusions:
Direct mail reminders and telephone contact with parents of children who were behind in their immunizations were effective methods to encourage compliance. The increased number of immunizations received by the children in the intervention group was overshadowed by the poor coverage of the entire practice, a highly mobile and predominantly indigent group. Additional interventions are urgently needed to improve immunization levels in infants and children.
