"Adverse events from drugs and vaccines are common, but underreported. Although 25% of
ambulatory patients experience an adverse drug event, less than 0.3% of all adverse drug events
and 1-13% of serious events are reported to the Food and Drug Administration (FDA).
Likewise, fewer than 1% of vaccine adverse events are reported. Low reporting rates preclude or
slow the identification of “problem” drugs and vaccines that endanger public health. New
surveillance methods for drug and vaccine adverse effects are needed. Barriers to reporting
include a lack of clinician awareness, uncertainty about when and what to report, as well as the
burdens of reporting: reporting is not part of clinicians’ usual workflow, takes time, and is
duplicative. Proactive, spontaneous, automated adverse event reporting imbedded within EHRs (Electronic Health Records)
and other information systems has the potential to speed the identification of problems with new
drugs and more careful quantification of the risks of older drugs.
Unfortunately, there was never an opportunity to perform system performance assessments
because the necessary CDC contacts were no longer available and the CDC consultants
responsible for receiving data were no longer responsive to our multiple requests to proceed with
testing and evaluation."
thanks. It's on page 6 of the PDF you linked to.
