The Manitoba Infant Feeding Database (MIFD) is being piloted as a surveillance system leveraging infant vaccination visits as a point of contact to collect infant feeding data during the first year of life. The objective of this study was to assess data quality and acceptability of the MIFD as a sustainable population-based surveillance system.
Internal completeness and internal validity were measured to assess data quality. Internal completeness was defined as the number of completed data fields out of the total number of data fields. Internal validity was defined as the proportion of translation errors from one level of the system, the paper questionnaire, to the next, the electronic database. A survey assessed staff's acceptance of data collection and submission processes.
A total of 947 records were reviewed. Data were 98.5% complete. Discrepancies were noted in 13.5% of data. The survey response rate was 78.4%. Nearly all respondents reported that the MIFD data collection tool was easy to use (96.6% agreed or strongly agreed). Whereas some challenges were identified, the majority were willing to continue with the MIFD data collection tool and process (93.1%).
Results from this evaluation suggest that the MIFD data collection process worked well; however, data validation will require human resources. The MIFD approach provides a sustainable mechanism for collecting data on infant feeding for surveillance and research purposes.
曼尼托巴婴儿喂养数据库(MIFD)正在试点作为一个监测系统,利用婴儿疫苗接种访问作为接触点,在生命的第一年收集婴儿喂养数据。本研究的目的是评估 MIFD 作为可持续的基于人群的监测系统的数据质量和可接受性。
内部完整性和内部有效性用于评估数据质量。内部完整性定义为已完成的数据字段数与总数据字段数的比例。内部有效性定义为从系统的一个级别(纸质问卷)到下一个级别(电子数据库)的翻译错误比例。一项调查评估了工作人员对数据收集和提交过程的接受程度。
共审查了 947 份记录。数据完整度为 98.5%。有 13.5%的数据存在差异。调查的回复率为 78.4%。几乎所有受访者都表示 MIFD 数据收集工具易于使用(96.6%的人表示同意或强烈同意)。虽然发现了一些挑战,但大多数人愿意继续使用 MIFD 数据收集工具和流程(93.1%)。
这项评估的结果表明,MIFD 的数据收集过程运行良好;但是,数据验证将需要人力资源。MIFD 方法为监测和研究目的收集婴儿喂养数据提供了可持续的机制。
