The study reveals that 10 percent of chemotherapeutic medications for outpatients
were prescribed or administered incorrectly. Though most were of little clinical
significance, in some patients the errors may have put the patients at risk
either for relapse or for overdose-related complications.
In the United States medical errors cause up to 98,000 hospital deaths per
year - more deaths than by motor vehicle accidents and breast cancer combined.
Medication errors are attributable to almost 7,000 inpatient deaths.
Medication errors in the outpatient setting are thought to be some of the
most common medical errors, but they are not well-studied, particularly in
children.. However, most mistakes among outpatients are caught before drugs
are given to patients, and because most drugs have wide safety ranges, most
errors are benign.
Children with cancer, however, receive extremely toxic drugs with narrow safe
dose ranges and must be prescribed according to specific, sometimes complex,
protocols.
Led by James A. Taylor, M.D. of the University of Washington and Children's Hospital
and Regional Medical Center in Seattle, researchers studied the rate and types
of medications errors that occur in children receiving outpatient chemotherapy
regimen for ALL. The authors reviewed the administration of drugs and the medications
prescribed and dispensed to 69 enrolled patients.
This study identified a 10 percent error rate in outpatient chemotherapy regimens
for children with ALL. "It is possible that the efficacy of treatment regimens
is reduced or toxicity increased because not all children are receiving the chemotherapeutic
agents as indicated," said Dr. Taylor. Moreover, the authors recommended, "in
designing new [chemotherapy] protocols, a balance needs to be struck between
the precision of dosing regimens and simplification so that medication errors
are minimized."
