Objective-To develop a practitioner led definition of a prescribing error f
or use in quantitative studies of their incidence.
Design-Two stage Delphi technique.
Subjects-A panel of 34 UK judges, which included physicians, surgeons, phar
macists, nurses and risk managers.
Main outcome measures - The extent to which judges agreed with a general de
finition of a prescribing error, and the extent to which they agreed that e
ach of 42 scenarios represented a prescribing error.
Results-Responses were obtained from 30 (88%) of 34 judges in the first Del
phi round, and from 26 (87%) of 30 in the second round. The general definit
ion of a prescribing error was accepted. The panel reached consensus that 2
4 of the 42 scenarios should be included as prescribing errors and that fiv
e should be excluded. In general, transcription errors, failure to communic
ate essential information, and the use of drugs or doses inappropriate for
the individual patient were considered prescribing errors; deviations from
policies or guidelines were not.
Conclusions-Health care professionals are in broad agreement about the type
s of events that should be included and excluded as prescribing errors. A g
eneral definition of a prescribing error has been developed, together with
more detailed guidance regarding the types of events that should be include
d. This definition allows the comparison of prescribing error rates among d
ifferent prescribing systems and different hospitals, and is suitable for u
se in both research and clinical governance initiatives.
