Promotional tactics by pharmaceutical companies can influence some doctors and may harm their prescribing according to an international team of researchers led by The University of Queensland.
These are the findings of a systematic review by Dr Geoffrey Spurling from The University of Queensland's School of Medicine, and colleagues from eight other institutions, to be published in this week's PLoS Medicine.
"We found no benefit for doctors from pharmaceutical promotion," Dr Spurling said.
"So doctors need to recognise these tactics and should instead use information sources that are independent of pharmaceutical companies."
The researchers reviewed all the available literature that has looked at information from pharmaceutical companies and how this influences doctors.
They found that in almost all cases studied, information from pharmaceutical companies could be associated with higher prescribing frequency, higher costs, and lower prescribing quality.
