Using information technology to reduce rates of medication errors in hospitals


David W Bates, chief.

Data continue to show that medication errors are frequent and that adverse drug events, or injuries due to drugs, occur more often than necessary. In fact, the frequency and consequences of iatrogenic injuries seems to dwarf the frequency of other types of injuries that have received more public attention, such as aeroplane and automobile crashes.
