Guest guest Posted February 10, 2010 Report Share Posted February 10, 2010 THE CLINICAL IMPACT OF ADVERSE EVENT REPORTING http://www.fda.gov/downloads/Safety/MedWatch/UCM168505.pdf Underreporting Another major concern with any spontaneous reporting system is underreporting of adverse events16,30-32. It has been estimated that rarely more than 10% of serious ADRs, and 2-4% of non-serious reactions, are reported to the British spontaneous reporting program30. A similar estimate is that the FDA receives by direct report less than 1% of suspected serious ADRs32. This means that cases spontaneously reported to any surveillance program, which comprise the numerator, generally represent only a small portion of the number that have actually occurred. The effect of underreporting can be somewhat lessened if submitted reports, irrespective of number, are of high quality Sheri Nakken, R.N., MA, Hahnemannian Homeopath Vaccination Information & Choice Network, Washington State, USA Vaccines - http://vaccinationdangers.wordpress.com/ Homeopathy http://homeopathycures.wordpress.com Vaccine Dangers, Childhood Disease Classes & Homeopathy Online/email courses - next classes start February 24 & 25 Quote Link to comment Share on other sites More sharing options...
