An exploration of counterfeit medicine surveillance strategies guided by geospatial analysis: lessons learned from counterfeit Avastin detection in the US drug supply chain.
Bottom Line: These data were used to generate the overarching study outcome, which was a recommendation for a strategy for drug safety surveillance congruent with existing literature on counterfeit medication.Importantly, the information generated by these analyses could be utilised to identify at-risk populations associated with demographic characteristics.Stakeholders should explore these results as another tool to improve on counterfeit medicine surveillance.

Mentions: Geospatial analyses indicated that the more correlated demographic variables were typically in higher categories in zip codes that had received counterfeit notices (figure 1). The most correlated demographic variables followed Poisson distributions, so three categories were designated for these variables: below 85th centile, 85th to 98.5th centile, and above 98.5th centile. This analysis also revealed a notable number of zip codes that had not received counterfeit notices, despite having relatively higher categories of identified demographic correlates. When conducting mapping of addresses for North American counterfeit distributors along with counterfeit notice recipients, visualisation revealed that some distributors appeared to be located among clusters of counterfeit notices (Southern California and New York), while other distributors did not appear to be located among clusters of counterfeit notices and were even located outside of the USA (ie, Canada; figure 2).
