Patient monitors rarely wear out. They age by their software: the manufacturer stops issuing updates, the operating system underneath stops receiving security patches, and the interface to the records system falls a version behind. By the time a hospital replaces them, the questions that decide whether the next fleet will age any better have usually been skipped.
1. When does software support end?
Ask the manufacturer for the end-of-support date for the model and the central station, in writing, and for its policy on security patches between releases. If the answer is shorter than your financing term, plan the refresh now.
2. What does the records interface cost, and who maintains it?
The interface that sends vital signs to the record is often priced separately and maintained by a third party. Find out whose problem it is when the record is upgraded.
3. Where does alarm data go?
Alarm middleware and secondary notification are where most of the clinical value of a new platform sits. Decide whether they are in scope before you compare quotes.
4. Is the central station hardware or software?
Some central stations now run on hospital servers. That shifts cost and responsibility to your IT team, which may be the right answer, but should be a decision.
5. What happens to the old fleet?
Monitors that are a generation old still have a market. Agree the trade-in value before installation, not after, and make sure the data on them is erased to a standard your privacy officer accepts.
Technology Refresh is our answer to the first question. The other four apply however you pay.
