Drug Reactions — a Major Cause of Death

Adverse drug reactions may cause the deaths of over 100,000 US hospital patients each year, making them a leading cause of death nationwide, according to a report in the Journal of the American Medical Association.
"The incidence of serious and fatal adverse drug reactions (ADRs) in US hospitals was found to be extremely high, " say researchers at the University of Toronto in Ontario, Canada.
They carried on an analysis of 39 ADR-related studies at US hospitals over the past 30 years and defined an ADR as "any harmful, unintended, and undesired effect of a drug which occurs at doses used in humans for prevention, diagnosis, or therapy. "
An average 6.7% of all hospitalized patients experience an ADR every year, according to the researchers. They estimate that "in 1994, overall 2,216,000 hospitalized patients had serious ADRs, and 106,000 had fatal ADRs. " This means that ADRs may rank
