Identifying natural health product and dietary supplement information within adverse event reporting systems

Data on safety and efficacy issues associated with natural health products and dietary supplements (NHP&S) remains largely cloistered within domain specific databases or embedded within general biomedical data sources. A major challenge in leveraging analytic approaches on such data is due to the inefficient ability to retrieve relevant data, which includes a general lack of interoperability among related sources. This study developed a thesaurus of NHP&S ingredient terms that can be used by existing biomedical natural language processing (NLP) tools for extracting information of interest. This process was evaluated relative to intervention name strings sampled from the United States Food and Drug Administration Adverse Event Reporting System (FAERS). A use case was used to demonstrate the potential to utilize FAERS for monitoring NHP&S adverse events. The results from this study provide insights on approaches for identifying additional knowledge from extant repositories of knowledge, and potentially as information that can be included into larger curation efforts.
