Background. The objective of this study is to evaluate whether a single pal
liative cancer care workshop, which included information about drug prescri
bing, had an effect oil the opioid-prescription patterns of general practit
ioners in daily practice. Method. The opioid-prescription figures of 68 gen
eral practitioners who had participated in the workshop were aggregated fro
m the computer system of the Regional Sick Fund. The prescription figures o
f a year before and a year after the workshop were compared and a control g
roup of non-participants was included. Results. This study showed a limited
efficacy of a palliative cancer care workshop oil the morphine-prescriptio
n figures of the general practitioners in daily practice. This limited effe
ct did not accord with the results of a pre- and post-workshop questionnair
e evaluating the attitudes of the same practitioners. Conclusion. A single
workshop can not effectuate substantial changes in prescription behaviors.
Possibilities for more reinforcements are discussed.
