Effets du Suivi des Enfants « Hors Zone » Vaccinés sur la Qualité des Données, District Sanitaire de San Pedro, Côte D'ivoire, 2019

In order to improve the quality of vaccination data from the health centers, we carried out the follow-up of “out-of-area” children, vaccinated in the district of San Pedro. The objective of this work was to measure the effects of taking into account the “out-of-area” vaccinated children on the quality of the data and the immunization performance of the health centers. This monitoring, which was carried out between March and August 2019, consisted of four steps: the vaccination of “out-of-area” children by the health center, the monthly update in the register of the status of vaccinated “out-of-area” children, the accounting of these children, and the re-evaluation of the health center's vaccine performance. A total of 37 of the 40 district centers had 980 “out-of-area” vaccinated children, representing 5.7% of the immunization target. The quarter of these children resided outside the district. The vaccination of “out-of-area” children included all EPI vaccines, but especially BCG, DTP-HepB-Hib and Pneumococcus_13. The number of “outside the extra-district area” vaccinated children had not changed the district's immunization coverage. On the other hand, in the health centers concerned, the accuracy of the data had been improved in 65% of the centers for DTP-HepB-Hib_1, in 70% of the centers for RR and in 65% of the centers for the overall immunization dropout rate. The approach used had made it possible to improve the quality of immunization data from health centers at no additional cost.
