The study examined insurance claims of 5.6 million
enrollees from 2001 to 2002 and found that medical errors do not necessarily
occur within the hospital only.
"Many hospitals are struggling to survive
financially," study co-author William Encinosa said in a statement.
"The point of our paper is that the cost savings from reducing medical
errors are much larger than previously thought."
The report said that
adding more nursing staff may be one of the ways to reduce medical errors. The
details appear in the journal Health Services Research.
