Preventive maintenance (PM) is planned inspection, testing, and servicing intended to keep medical equipment ready and identify problems before they interrupt care. A strong program connects each task to the correct device, instructions, risk, and service record.
Begin with the inventory
The inventory is the control point for a PM program. Record a unique asset identifier, manufacturer, model, serial number, location, owner, service status, and applicable maintenance plan. If these fields are inaccurate, even a carefully written procedure can be applied to the wrong device or missed entirely.
Set the correct procedure and interval
Manufacturer instructions are the starting point. A hospital may use an Alternate Equipment Management program only where applicable CMS conditions are met; some categories and circumstances have restrictions. A technician should not shorten or extend an interval simply because another hospital does so. The documented policy, qualified assessment, device history, and applicable rules govern the decision.
Record more than a completion checkbox
A useful PM record identifies who performed the work, the procedure version, date, test instruments, results, exceptions, corrective actions, and final disposition. If a unit fails, clearly separate it from ready-to-use stock and follow local escalation rules. Avoid recording protected patient information in routine asset notes.
Measure program performance
Track overdue high-risk equipment, repeat failures, unavailable parts, devices that cannot be located, and repairs following PM. Completion percentage alone can hide a poor inventory or a high repeat-failure rate. Review trends with clinical owners and change the process where the evidence warrants it.
Practical decision aid
- Before opening a work order, confirm the asset ID, location, configuration, and currently approved procedure. A correct test on the wrong configuration does not close the maintenance obligation.
- Record an as-found exception before repair or adjustment. Without that record, a later reviewer may be unable to distinguish an existing fault from a successful final test.
- Review overdue work by risk and clinical availability, not only by the number of open tickets. A low-risk backlog and an unavailable high-risk device should not be treated as equivalent.
