In looking at OpenFDA, I'd like to know the range of values for results.seriousnessother, results.seriousnesshospitalization, results.serious, and results.primarysource.qualification, as well as what they mean.

If you take a look at our API documentation (http://open.fda.gov/drug/event/reference/), you'll see a complete reference for every field we return and the range of possible values. We follow the E2b specification for adverse drug reporting (http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Surveillance/AdverseDrugEffects/UCM350390.pdf).

For the specific examples you provided, here's what our documentation reads:


This value is 1 if the adverse event resulted in a hospitalization, and absent otherwise.


1 = The adverse event resulted in death, a life threatening condition, hospitalization, disability, congenital anomali, or other serious condition.

2 = The adverse event did not result in any of the above.


An encoded value for the category of individual submitting the report.

1 = Physician

2 = Pharmacist

3 = Other Health Professional

4 = Lawyer

5 = Consumer or non-health professional


If you use our search tool you can find a graph (last one of 5) that tabulates the results.primarysource.qualification into a bar graph for your search query. http://openfda.socialhealthinsights.com/


You might want to check out http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Surveillance/AdverseDrugEffects/UCM350390.pdf for more information on the data in these reports.
