Primary care physicians report high trust in and usefulness of the Stockholm drug and therapeutic committee's list of recommended essential medicines (the 'Wise List').

We found that the essential medicines formulary was widely used and trusted by the prescribers. The high uptake of the treatment recommendations could be due to the Stockholm Drug and Therapeutics Committee's transparent process for developing recommendations involving respected experts and clinicians using strict criteria for handling potential conflicts of interest, feedback to prescribers, continuous medical education and minor financial incentives.
