I'm dipping my toes into the openFDA dataset and want to do some searches related to congenital anomalies. I know this data is searchable because the folks at Social Health Insights have built a wonderful tool utilizing this as a search parameter.

I've done some reading about the fields in the FAERS structure and the following queries work:

  1. ?search=_exists_:seriousnessdeath&limit=5
  2. ?search=_exists_:seriousnesslifethreatening&limit=5
  3. ?search=_exists_:seriousnesshospitalization&limit=5
  4. ?search=_exists_:seriousnessdisabling&limit=5
  5. ?search=_exists_:seriousnessother&limit=5

But the same query doesn't work for seriousnesscongenitalanomaly


Any ideas what I'm doing wrong?

Thanks for the complement on our ResearchAE.com project. Glad you found it useful and as an example of what people can do with the openFDA data.

To answer your question, I believe the query you mean to be doing is this:

  • Perfect. Thanks, Mark. Keep up the good work at ResearchAE.

  • Ryan - No problem! BTW - I noticed from your profile that you're in Indy too. Consider tweeting out to @geek_nurse who is in Indy too and built most of researchae.com. Have fun! Jul 26, 2014 at 15:02
