[영문]The Vaccines for Children (VFC) program supplies health-care providers withfederally purchased vaccines at no cost for administration to eligible children.Evaluation of vaccine accountability activities ensures appropriate and timelyvaccinations are delivered. Program grantees in 50 states, Washington,five large U.S. metropolitan cities, and five U.S. territories and possessionscompleted a Web-based survey between December 2002 and January 2003focused on current vaccine accountability operational systems.Most grantees required providers to complete profiles describing thevaccination needs and demographics of their practices. More than halfrequested providers use benchmarking data, doses-administered reports,and/or claims or encounter data to determine their VFC program-eligiblepopulation size; however, .65% did not have written procedures forinvestigating and reconciling discrepancies between estimated vaccine needsand actual vaccine-use data. Most grantees had written standard policiesrequiring providers to report vaccine loss and wastage routinely and to explainwhy they occurred. Ninety percent of grantees did not have procedures tocheck providers for fraud and abuse sanctions, and 52% did not have writtenprocedures to address complaints of vaccine fraud and abuse.These results suggested specific areas in which the Centers for DiseaseControl and Prevention should work with grantees to improve vaccineaccountability practices. As a result, enhancements to the VFC program arebeing implemented to address these areas and their impact evaluated fortheir effectiveness in ensuring the continued success of the VFC program inprotecting the nation’s most vulnerable children and adolescents.
