[Quality of immunization data in children aged 0 to 11 months in Côte d’Ivoire]
Insights
Immunization data accuracy was good at the district level but poor at the health center level in Côte d’Ivoire. Supportive supervision is recommended to improve data reporting and the immunization tracking system.
Area of Science:
- Public Health
- Health Systems Research
- Data Quality Management
Context:
- A 2012 immunization Data Quality Self-Assessment was conducted in Côte d’Ivoire to inform program managers.
- The study assessed immunization data accuracy and tracking system quality.
Purpose:
- To evaluate the accuracy of immunization data using the verification factor (VF).
- To assess the quality of the immunization tracking system.
- To identify areas for improvement in immunization data management.
Summary:
- A cross-sectional study in 88 facilities across 30 districts found data accuracy satisfactory at the district level (VF=95%) but not at the health center level (VF=81%).
- The overall quality index for the immunization tracking system was unsatisfactory at both district (64%) and health center (50%) levels.
- Weaknesses were identified in "supervision and monitoring" and "analysis and use of data" components.
Impact:
- Findings highlight critical deficiencies in immunization data reporting and tracking systems.
- Results underscore the need for enhanced supportive supervision to improve data quality and system performance.
- Recommendations aim to strengthen immunization program management through better data utilization.
Introduction:
In order to guide the decisions of programme managers, an immunization Data Quality Self-Assessment was performed in Côte d’Ivoire in 2012. This study was designed to assess the accuracy of immunization data and the quality of the immunization tracking system with this tool.
Methods:
A descriptive cross-sectional study was conducted in 88 randomly selected immunization facilities from 30 health districts. These structures were included in the study based on the number of children aged 0-11 months who received three doses of vaccine against Diphtheria, Tetanus, Pertussis, Hepatitis B Viral and Haemophilus Influenzae b on the one hand and measles vaccine coverage on the other. This assessment focused on two criteria in particular: accuracy of immunization data measured by the verification factor (VF) and the quality of the immunization tracking system.
Results:
The accuracy of immunization data was satisfactory at the district level (VF=95%), but not for the health centre level (VF=81%), as 73% of health districts and health centres obtained a satisfactory factor (≥95%).The number of children aged 0-11 months vaccinated differed from one level of the health system to another and from one document to another.The mean quality index was not satisfactory for both the district and health centre levels (64% vs 50%). Only one health district and one health centre obtained a quality index greater than 80%. Furthermore, 93% of health districts and 50% of health centres obtained quality indices ranging from 50% and 80%, respectively.The weakest components at both levels were “supervision and monitoring” and “analysis and use of data”.
Conclusion:
The deficiencies in data reporting and the quality of the immunization monitoring system need to be improved by supportive supervision.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
