Naïve as I was, I found myself astonished at the level of detail that drug companies were able to acquire about doctors’ prescribing habits. I asked my reps about it; they told me that they received printouts tracking local doctors’ prescriptions every week. The process is called “prescription data-mining,” in which specialized pharmacy-information companies (like IMS Health and Verispan) buy prescription data from local pharmacies, repackage it, then sell it to pharmaceutical companies. This information is then passed on to the drug reps, who use it to tailor their drug-detailing strategies. This may include deciding which physicians to aim for, as my Wyeth reps did, but it can help sales in other ways. For example, Shahram Ahari, a former drug rep for Eli Lilly (the maker of Prozac) who is now a researcher at the University of California at San Francisco’s School of Pharmacy, said in an article in The Washington Post that as a drug rep he would use this data to find out which doctors were prescribing Prozac’s competitors, like Effexor. Then he would play up specific features of Prozac that contrasted favorably with the other drug, like the ease with which patients can get off Prozac, as compared with the hard time they can have withdrawing from Effexor.
