Evaluation of introduction of the Haemophilus influenzae vaccine in Côte d'Ivoire / Évaluation de l'introduction du vaccin anti-haemophilus influenzae en Côte d'Ivoire.

Introduction: Côte d'Ivoire introduced the Haemophilus influenzae type b vaccine into the EPI in March 2009. Following this introduction, an evaluation was conducted in 2012 in order to evaluate the vaccine introduction process. Methods: Data collection methods consisted of document review, structured interviews and direct observation. This study collected information from six health region officials, 12 health districts and 36 healthcare institutions. Seventy-two mothers or child carers were also interviewed. Collected data were processed and analysed by Excel, Epi Info and SPSS. Results: A vaccine introduction plan was developed, but was not communicated at the operational level. The planned training for district health care providers was conducted eighteen months after introduction of the vaccine. None of the vaccinating centres had communication support about the new vaccine. Temperature recording was regularly performed in 92% of district deposits and 68% of vaccinating centres. Deteriorated vaccines were observed in 6% of vaccinating centres. Only 3.5% of parents had been informed about introduction of the vaccine. Increased immunization coverage for the third dose of pentavalent vaccine was observed in one half of health districts. Conclusion: Evaluation of the introduction of Haemophilus influenzae type b vaccine highlightsthe strengths and weaknesses of the health system and provides lessons for the introduction of other vaccines into the expanded programme on immunization.

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.
