Perioperative medication error rates higher than expected
A study conducted at Massachusetts General Hospital in Boston found that almost half of 277 randomly selected operations involved a medication error or adverse drug event.

Medicines that are given to patients during surgery may not be subject to the same checks as medicines used in other settings and the stressful environment means errors may be more likely. However, data on perioperative medication errors are sparse and largely self-reported.
A team from Massachusetts General Hospital in Boston observed medication errors and adverse drug events during 277 randomly selected operations over an eight-month period. Overall, 124 (44.8%) operations involved a medication error or adverse drug event. And, among 3,671 medication administrations, 193 (5.3%) were affected by at least one of these outcomes.
These rates are markedly higher than those reported in retrospective surveys. But the researchers note that, as their hospital has already implemented measures to reduce medication errors, it is likely that the observed rates are comparable to — or even lower than — those at other institutions.
