Computer-generated recall letters for underimmunized children : how cost-effective ?
To evaluate the effectiveness and cost effectiveness of computer-generated recall letters to parents of children overdue for immunizations.
This randomized controlled trial included children of two facilities in a regional health maintenance organization.
Parents of 20-month-olds who had not yet received a measlesmumps-rubella (MMR) immunization were identified via a computerized immunization tracking system.
One half were mailed personalized letters that included the recommended immunization schedule and a request to call for an appointment ; the other half served as a control group.
Receipt of the MMR between 20 and 24 months of age was evaluated with the computerized tracking system.
A telephone survey was conducted with parents whose children had not received the MMR by 24 months.
Decision analysis was used to project the theoretical outcomes and costs of a recall letter policy for other populations.
Among 20-month-old children 10% had not received the MMR ; 289 families were included in the analysis.
Of families who were mailed letters, 54% (82 of 153) received the MMR by 24 months of age, compared with 35% (47 of 136) of those in the control group (P=0.001).
The telephone survey was completed with 110 parents of children who still did not appear on the health plan computer as having received the MMR by 24 months. (...)
