How can I structure a question on the FDA OpenApp that will return all Class 1 and 2 medical device recalls for radiation therapy devices over a certain period (e.g. the month of June 2014)?
The short answer is as follows (here is a clickable link though) which searches for recalls initiated during June 2012, that were classified as Class I or Class II, and had the word "radiation" somewhere in the recall documentation.
There are a number of caveats to keep in mind though:
- This query relies on "radiation" being included in one or more of the fields listed at https://open.fda.gov/device/enforcement/reference/ such as
product_descriptionbut there is absolutely no guarantee radiation drugs will mention that keyword.
- This query also relies on
recall_initiation_datebe present which appears to only be there for 59% of all the device enforcement reports available in the API (4639 of the 7855). Note that field
report_dateseems to have 100% coverage. Maybe the
recall_initiation_datefield is only available after a certain date? More digging needs to be done to make that call.
