Accurate and timely vaccination data are important to the Expanded Program on Immunization (EPI) to assess individual vaccination status and to monitor performance and vaccine coverage (VC). Since 2013, Burkina Faso introduced several new vaccines into the routine childhood immunization schedule. However, sustained efforts for a timely update and alignment of immunization home-based (HBRs) and health facility-based records (FBRs) with the evolving schedule were not implemented.
In 2016-17, we conducted a 6-week cross-sectional survey in 30 health facilities (HFs) across 10 health districts (HDs), targeting children aged < 24 months and their caregivers. Data collected included sociodemographics, availability of vaccination recording fields in HBRs, and vaccination dates. We evaluated the characteristics, completion patterns, and concordance of HBRs and FBRs to determine their reliability as data sources in estimating VC. A standard HBR was defined as one that had recording fields for all recommended 17 vaccine doses of the schedule, and discordance between HBR and FBR as having different vaccination dates recorded, or vaccination information missing in one of the records. We computed proportions and concordance statistics, and used logistic regression to explore predictors of discordance.
We recruited 619 children, including 74% (n = 458) aged 0-11 months. Half (50.6%) of HBRs were non-standard. About two-thirds (64.6%) of children were concerned with discordant information. Compared to HBRs, FBRs were generally associated with low negative predictive values (median: 0.41; IQR: 0.16-0.70). Multivariate logistic regression model showed that standard HBR was protectively associated with discordant information (OR = 0.46, 95% CI: 0.26-0.81, p = 0.010).
We documented a lack of standardization of HBRs and frequent information discordance with FBRs. There is a pressing need to update and standardize vaccination recording tools and ensure their continuous availability in HFs to improve data quality in Burkina Faso.
准确、及时的疫苗接种数据对于扩大免疫规划（EPI）至关重要，可用于评估个体的疫苗接种状况，并监测绩效和疫苗覆盖率（VC）。自 2013 年以来，布基纳法索在常规儿童免疫计划中引入了几种新疫苗。然而，并没有持续努力及时更新和调整免疫家庭记录（HBR）和卫生机构记录（FBR），使其与不断变化的时间表保持一致。
2016-17 年，我们在 10 个卫生区的 30 个卫生机构中进行了为期 6 周的横断面调查，调查对象为年龄<24 个月的儿童及其照顾者。收集的数据包括社会人口学特征、HBR 中疫苗接种记录字段的可用性以及疫苗接种日期。我们评估了 HBR 和 FBR 的特征、完成模式和一致性，以确定它们作为估计 VC 的数据源的可靠性。标准 HBR 定义为具有计划推荐的 17 剂疫苗所有记录字段的记录，HBR 和 FBR 之间的差异定义为记录的疫苗接种日期不同，或者一份记录中缺少疫苗接种信息。我们计算了比例和一致性统计数据，并使用逻辑回归模型探索了差异的预测因素。
我们招募了 619 名儿童，其中 74%（n=458）年龄为 0-11 个月。一半（50.6%）的 HBR 是非标准的。大约三分之二（64.6%）的儿童存在不一致信息。与 HBR 相比，FBR 的阴性预测值通常较低（中位数：0.41；IQR：0.16-0.70）。多变量逻辑回归模型显示，标准 HBR 与不一致信息呈保护相关（OR=0.46，95%CI：0.26-0.81，p=0.010）。
我们记录了 HBR 缺乏标准化和与 FBR 频繁信息不一致的情况。迫切需要更新和标准化疫苗接种记录工具，并确保在卫生机构中持续提供这些工具，以提高布基纳法索的数据质量。
