Most drug side effects not due to error, study says
The vast majority of adverse drug events are side effects from a drug that was prescribed as intended, rather than being the result of a drug administration error, according to recent research.
In 2004, 1.2 million hospitalized patients experienced an adverse drug event, 90% of which were due to a side effect from a medication that was properly administered, according to the latest figures from the Agency for Healthcare Research and Quality in Rockville, MD.1 AHRQ also found that just 8.6% of adverse drug events among hospitalized patients were because they were given the wrong drug or the wrong dose in the hospital or because they accidentally took an overdose or the wrong drug before entering the hospital.
