Dr. Deborah Harrigan remembers the day two pharmaceutical company representatives told her she wasn't prescribing enough of a drug they sold.
The Rochester family physician, who was working at the city's Avis Goodwin Community Health Center at the time, said she was surprised they knew so much about her prescribing history.
The information comes from data mining companies, which collect, analyze and sell details about the type of prescriptions Harrigan and other physicians write. The practice isn't without controversy — Harrigan, for example, said she believes doctors at least should be told if their data is being collected and sold. That isn't now required.
