Preventing Medication Errors
Implement safe medication practices.
To Err is Human identied medication errors, “as a sub-
stantial source of preventable error in hospitals.”

The re-
port recommended stronger oversight by the Food and Drug
Administration (FDA) to address safety issues connected
with drug packaging and labeling, similar named drugs, and
post marketing surveillance by doctors and pharmacists.
17
In
2006 the IOM returned to the issue, publishing “Prevent-
ing Medication Errors,” a report that reiterated many of the
recommendations of the 1999 report and concluded that at
least 1.5 million preventable medication errors cause harm
in the United States each year. The 2006 report estimated
that medication errors in hospitals alone cost $3.5 billion a
year.

Drug Confusion Errors
Many medication errors are caused by the confusion of med-
icines with similar names,
such as primidone (a seizure
medication) and prednisone
(an anti-inammatory medi-
cation). For example, the sim-
ilarities of these names led to
the death of an adolescent in
California in a case reported in
2004, despite the fact that the
potential for primidone-pred-
nisone confusion had been
identied three years earlier.
19,20
The confusion continues.
A 2008 report listed Predni-
sone as commonly confused
with 12 other drugs
21
Packaging and design can
also contribute to drug confusion errors. In a high prole
case in 2007 the twin babies of actor Dennis Quaid and his
wife were given 1,000 times the prescribed dose of the blood
thinner heparin. According to Quaid’s testimony before Con-
gress, the couple sued the drug manufacturer, charging that
the manufacturer was negligent in packaging different doses

The
court dismissed the case on jurisdictional grounds and it is
now on appeal. This problem was not new. A year before, a
similar mix-up ocurred when six infants in a newborn inten-
sive care unit at an Indianapolis hospital were given excessive
doses of heparin, leading to the death of three of them, and
two infants at the same Indianapolis hospital had received a
similar overdose in 2001.
23
After the Indianapolis deaths, the
manufacturer issued a letter warning hospitals of the poten-
tial for confusion, but the packaging was not changed for at
least 12 months and the same packaging was still being used
in the hospital treating the Quaid children.
24
After the Quaids
threatened to sue the hospital where their twins were treated,
the hospital agreed to pay the family $750,000 and invested
$100 million in new technology to prevent similar harm in
the future.
25
Regulators ned the hospital for failure to fol-
low its own safety policies.
26
Most victims of medication error do not have the same abil-
ity to drive media attention and prompt action. There were
25,530 look-alike and/or sound-alike drug confusion errors
reported to two drug error reporting systems in the four years
2003-2006; drug labeling and packaging contributed to 7.8%
of look-alike and/or sound-alike errors.
27
With a problem of
this magnitude, we need a systematic solution to address all
of the confusion errors, not just the few that get media at-
tention.
The FDA has tested new drugs for potential name confusion
since 1999 and monitors the market for instances of confu-
sion, but few existing names are changed.
28
In an unusual ac-
tion in 2005 the FDA called for the Alzheimer’s drug Rem-
inyl to be renamed after confusion with the diabetes drug
Amaryl was implicated in two patient deaths. Reminyl was
renamed Razadyne.
29
The current statistics on look-alike/sound-alike error demon-
strates that the FDA’s effort is inadequate. The FDA is con-
ducting a pilot program to expand pre-market drug testing to
include name confusion evaluation by third parties, but the
