Assessment of immunization status in hospitalized children followed by counseling of parents and primary care physicians improves vaccination coverage: an interventional study.

This prospective, intervention-control study in hospitalized, underimmunized children assessed the effect of vaccination reminders to parents during hospitalization and provides postdischarge rates of catch-up immunizations. One month after hospital discharge, significantly more children in the intervention group (27%) than the controls (8%) had received catch-up immunizations (P < .001).
