These commitments are enforceable. Just not by anyone they are made to.

In September the Governor of North Carolina wrote to the parties in a hospital combination to say he could not support it “without a commitment to keep health care costs down for people in Wake County”, and asked for “an enforceable cap on annual price increases”. The parties accepted one. Within four days he said: “I do not oppose the combination.”

So we went looking for who can make a commitment like that stick. In seven such packages, across six jurisdictions and four decades, not one gives a patient, an employer, a payer or an employee any right to enforce it.

That is a finding about the instruments we could read on the public record, not a claim that nobody is ever held to account.

We read the instruments rather than the commentary about them: terms of certification, attorney-general conditional consents, transfer-agreement amendments, consent judgments and the reports of appointed monitors. Every claim we cite was checked against the document it came from, and where a document could not be read we say so rather than fill the gap.

Every guardrail we examined is enforceable at the discretion of one public official. Not the patients whose prices are capped, not the employers who pay those prices, not the insurers, not the staff. If that official decides not to act, nothing happens. Faced with comparable categories of shortfall, one jurisdiction recorded an internal accounting entry and moved on, and two others went to court.

What the instruments get right

The only systematic evaluation of these regimes finds that properly designed conditions “can effectively constrain prices in the absence of competition among providers”. That deserves saying first, because the public argument rarely allows for it. The drafting is improving too: nine distinct answers to documented failures already exist in filed documents and can be adopted by copying rather than invented. No package we read contains more than three of them.

Two things surprised us

Our view, for what it is worth

The question usually asked of these packages, whether guardrails work, cannot presently be answered for most of them. Two of the four kinds of commitment we looked at, charity care and governance, have no outcome evidence at all. A narrower question can be answered, and answered early: is this particular package capable of working? One that controls the wrong quantity, covers less than the system it governs, or names nobody who can compel it cannot be effective whatever data arrives later, because the mechanism through which it would work is absent. That is legible in the document, before the transaction closes.

Those are questions, not advice. The answers belong to the board, the authority or the coalition that has to live with them, and we take no view on any particular transaction.

We looked at what the public record holds. If you have read an instrument that does give a patient or an employer a way to enforce one of these commitments, we would like to see it.
