Share vials and round doses to stop throwing away expensive drug

Weight-based doses rarely match vial sizes, so the leftover is discarded and still billed; closed-system vial sharing and rounding doses to the nearest vial within 10% eliminate most of that waste.

Medicare pays for discarded drug under the JW modifier and, since 2023, requires refunds from manufacturers for waste above 10% under the Infrastructure Investment and Jobs Act. Pharmacies can avoid the waste in the first place: closed-system transfer devices extend the in-use stability of single-dose vials so one vial serves several patients, and dose banding (rounding to the nearest vial size within a defined tolerance) is standard in the NHS. Both are cheap and can be implemented by a hospital pharmacy in months.

Hypothesis

Dose rounding and vial sharing will reduce discarded drug for the ten highest-spend Part B oncology drugs by more than 70% in participating centres.

Rationale

The NHS national dose-banding tables and multiple US single-centre studies report six- and seven-figure annual savings per institution.

What would test it

Pharmacy-level before-and-after audits of JW-modifier billing and drug spend, with a registry of any stability or safety issues.

Bottlenecks it attacks

Prices and value · New cancer drugs routinely cost over $150,000 a year, often for months of benefit. Systems cannot afford them and patients go bankrupt.
Wrong doses · Most drug doses were chosen as the highest a person can tolerate, which is often more than they need.
