Medical Device Technology and Lifecycle Management
What this domain tests
This domain tests your ability to manage equipment from capital request through disposal using a risk-based, documented program. It draws on ANSI/AAMI EQ56 for medical equipment management programs and on NFPA 99 and CMS conditions for maintenance strategies, including alternative equipment maintenance (AEM).
Core rules
- Lifecycle phases: needs assessment and capital planning → specifications and procurement → acceptance testing → inventory and CMMS entry → maintenance and calibration → recall/alert management → decommissioning and disposal.
- Acceptance testing verifies performance, electrical safety, and configuration against the manufacturer's specifications before clinical use; it is not optional paperwork.
- Risk-based maintenance: set PM intervals from manufacturer recommendations, device risk, failure history, and clinical criticality. AEM intervals must be justified, documented, and approved, and cannot be applied to certain high-risk devices where manufacturer instructions must be followed.
- Recall management: receive, screen, triage, execute, and close alerts; record the action taken and the date for every affected asset.
- Decommissioning: remove from inventory, sanitize data and storage media, manage batteries and e-waste, and account for radiation sources.
Worked example
A hospital wants to extend infusion pump PM from 6 to 12 months. Reasoning: first stratify the fleet by risk and failure history; pull CMMS work orders and vendor service data; confirm the manufacturer does not prohibit the interval; define performance checks that will still be performed; obtain medical director and safety committee approval; run a pilot with defined failure thresholds and a rollback plan. The extension is defensible only with this documented evidence, not because “the pumps seem fine.”
Traps that cost marks
- Skipping acceptance testing because the vendor says the device is “pre-tested.”
- Extending PM intervals without a written AEM justification and approval.
- Treating inventory as a one-time list rather than a living record tied to work orders and recalls.
- Disposing of devices with patient data still on them.
