Often, the only information about medicines that practitioners receive is provided by the pharmaceutical industry and may be biased. Provision of independent (unbiased) information is therefore essential. Drug information centres (DICs) and drug bulletins are two useful ways to disseminate such information. Both may be run by government or a university teaching hospital or a nongovernmental organization, under the supervision of a trained health professional, Whoever runs the DIC or bulletin must (1) be independent of outside influences and disclose any financial or other conflict of interest, and (2) use evidence-based medicine and transparent deduction for all recommendations made. The WHO Model Formulary provides independent information on all medicines in the WHO Model List of Essential Medicines.
