The effects of prescribing guidelines for analgesia were assessed by a
uditing prescriptions for opioids before and after the introduction of
hospital prescribing guidelines. Opioid prescriptions were collected
by the pharmacy department over a 2-week period in November 1994 and r
epeated in November 1995. Following the initial audit, analgesic presc
ribing guidelines were introduced. A statistically significant increas
e was achieved in the number of prescriptions that were correct for bo
th dose and frequency according to both the British National Formulary
recommendations (40-61%; p < 0.001) and our Acute Pain Sendee guideli
nes (16-26%; p < 0.05). There was a statistically significant decrease
in the number of prescriptions that were inadequate for both dose and
frequency according to both the British National Formulary recommenda
tions (18-3%; p < 0.001) and our Acute Pain Service guidelines (36-17%
; p = 0.001). The ase of accessible prescribing guidelines promotes de
monstrable improvements in opioid prescribing.
