Running title: Sources of drug information among physicians


Introduction: Irrational drug usage is a serious issue around the world. According to the World Health Organization (WHO), more than half of pharmaceuticals are prescribed, administered, or sold incorrectly, and a high percentage of patients do not take their medications properly. Anecdotal evidence from community pharmacies within the study site showed an alarming rate of prescription errors. Pharmacists can influence prescribing physicians' behaviour by providing appropriate drug information. This study aims to examine the most common sources of drug information among physicians in Kaduna Metropolis, Nigeria and its influence on physician prescription decisions. Methodology: A cross-sectional survey was conducted among physicians across two tiers of facilities, secondary and tertiary hospitals. A self-administered questionnaire was distributed to physicians working at both public and private hospitals and 93 were retrieved. Data were analysed using frequencies and percentages, while inferences were made using chi-square at p-value ≤0.005 and cross-tabulation. Results: About 53% of respondents were within the age of 20 and 30 years and had more than 5 years of experience. Physicians' preference for drug information sources were consult monographs 68%, refer to medical peers 69% and ask pharmacists 41%. In secondary and tertiary hospitals respectively 49% and 53% of respondents selected official monographs as their source of drug information, while 43% and 57% consider pharmacists for advice. Dosing regimens and safety concerns were the two primary factors driving the demand for drug information, whereas pharmaceutical forms received less attention. Internet was the most preferred choice when drug safety is a concern. conclusion: pharmacists were merely considered as drug information providers by respondents, as they preferred to seek drug information from physician colleagues, monographs, and internet.
