This is happening with health insurance companies in Singapore. It sets a worrying precedent where patient/doctor confidentiality becomes obsolete. I'm not against my health data being collected anonymously for research purposes but I sure don't want the researcher to be my health insurance company.
HIPAA would like to have a word with you.
> "It'd be cool if you kept that data encrypted at rest and kept track of every time it's accessed. Oh, you guys have a physical form everyone fills out when they access files? Perfect." - HIPAA in practice
Wholesalers don't have patient data. They sell to pharmacies. Still VERY valuable data, but HIPPA shouldn't be an issue.
