CMS Data · Payments & prescribing

Do paid doctors prescribe differently?

The money drug and device makers give to individual doctors is public, and so is what every doctor prescribes. But the two records sit far apart, so the obvious question almost never gets asked. Putting them together used to be slow, expensive work. Now you just ask, and within seconds you can see whether the doctors a company pays also prescribe its products more than their peers do, carefully, as a pattern, not proof about any one doctor.

The problem

The money and the prescriptions were never together.

The payments companies report giving doctors, the dinners, the consulting fees, the speaking honoraria, are published in one place. What each doctor actually prescribed is published in another. To ask whether the two connect, someone first had to match the doctors across both records, line the product up to the prescription, and compare like with like, since a heart doctor and a psychiatrist are nothing alike. That work is exactly why this kind of look rarely gets done.

Put the payments and the prescriptions side by side and the pattern is visible without overclaiming. You can group doctors by whether they took money tied to a drug and compare how much of that drug each group prescribed. The result is a correlation, a pattern, not a verdict on any single doctor, but at scale that pattern is exactly what the public information was meant to surface. The answer that used to take weeks now takes seconds.

What it answers

Questions you can finally ask.

Each is a question you simply ask and get an answer to, not a three-week analysis project.

Do paid doctors prescribe a drug more?

Compare how much of a drug doctors prescribe when they were paid by its maker versus when they weren't, within the same specialty.

Which drugs show the steepest gap?

Rank drugs by the difference in prescribing between paid and unpaid doctors, surfacing where the pattern is strongest.

Does more money mean more prescribing?

Group doctors by how much they were paid for a product and see whether prescribing rises with the money or stays flat.

Which specialties show it most?

Break the comparison out by specialty to see where payments and prescribing track closely and where they barely move together.

Is it meals and fees, or research money?

Separate everyday payments from research funding to see whether the pattern attaches to one kind of money more than the other.

Which doctors stand out on both?

Find the doctors who are high on payments and high on the matching drug at once, the standouts worth a closer, careful look.

What goes into it

What the answer pulls together.

What doctors are paid by industry

The everyday payments makers report giving doctors, meals, consulting, speaking, travel, each tied to a product and a dollar amount.

Research funding, kept separate

Money tied to research, tracked on its own so you can tell research dollars apart from promotional ones.

What those doctors prescribe

What each doctor actually prescribed, drug by drug, the prescribing side of the comparison.

A pattern isn't proof, and the public record can't read any one doctor's mind. But at scale it can tell you exactly where the money and the prescriptions move together, and that's worth knowing.

Common questions

What people ask about this.

Doesn't this say doctors are being bought?

No, and the answer is written to avoid that claim. A link between payments and prescribing has plenty of innocent explanations, a doctor may be paid precisely because they already specialize in that drug's area. The honest result is a pattern across many doctors, by specialty and drug, an invitation to look closer, not a judgment about any one person.

How do you match a payment to the right drug?

Each payment is tied to a product, and the prescribing record names the drug, so the two can be matched up. Comparing only doctors in the same specialty keeps it fair, since prescribing habits differ wildly across fields. That matching is the hard part, which is why this rarely gets done well.

How current is the answer?

It stays current on its own. When new information is published, it's already in there, so you're asking against today's picture, not a year-old extract.
