Principles for more predictable clinical operations
- The program should include functional inspection, safety inspection, preventive maintenance and documented corrective work.
- Manufacturer recommendations, applicable regulation and facility experience determine frequency—not a generic timetable.
- Data, software, networking and workstations are also clinical dependencies.
- Every intervention should leave a trace: work performed, responsible person, result, parts and next due date.
1. Build an inventory that supports decisions
Record every asset with a stable identifier, location, manufacturer, model, serial number, acquisition date, warranty, supplier, criticality and internal owner. Add manuals, contracts, service history, consumables and parts. A photograph and label help prevent confusion between similar devices.
The inventory should include connected digital infrastructure: acquisition computer, server, storage, operating system, software version, license, network, printer, backup device and receiving system. If a dependency can stop the workflow, it belongs in the operational inventory even when it is not a medical device.
- Criticality to care and availability of an alternative.
- Electrical, environmental and connectivity requirements.
- Daily-use owner and technical owner.
- Documents, license keys and support contacts.
- Status: active, reserve, out of service or awaiting retirement.
2. Prioritize according to risk, use and recommendations
Not every asset needs the same frequency. Consider risk to patients and operators, intensity of use, environment, failure history, backup availability and manufacturer or authority requirements. Critical equipment and assets with no substitute deserve stricter controls.
Separate performance inspection, safety inspection, preventive maintenance and corrective maintenance. Cleaning or updating a workstation does not replace a technical device check; a one-time repair does not replace a preventive program. Each task needs a scope, required competency and acceptance criterion.
- Schedule based on verifiable recommendations.
- Task list specific to the device family or model.
- Controlled tools, standards and test equipment.
- Criteria for stopping use and labeling the asset.
- Escalation path to authorized service when required.
Work affecting safety, calibration or clinical performance must be performed by competent personnel and follow manufacturer instructions and applicable regulation.
3. Include software, data, networking and cybersecurity
A workstation can power on and still fail within the workflow: low storage, a damaged database, expired license, incorrect time, incompatible security software, unstable networking or an unvalidated update. Document the approved configuration and control changes before applying them in production.
Define backups for data and configuration, test restoration and separate daily-use accounts from administrative accounts. Enable multifactor authentication where available, limit remote access and record who may connect. Coordinate security updates with clinical compatibility and manufacturer support; do not improvise on regulated equipment.
- Available capacity, storage health and error logs.
- License state, supported version and dependencies.
- Backup of studies, configuration and databases.
- Network segmentation and controlled remote access.
- Rollback plan for changes and updates.
4. Turn every intervention into a work order
The order should identify the asset, reason, date, initial condition, tasks, measurements, parts, result and responsible person. When work remains incomplete, document why and what happens next. Update the history and clearly mark equipment status after completion.
This discipline reveals repeated failures, slow providers, problematic parts and equipment whose maintenance cost is no longer justified. It also removes dependence on one person’s memory. Useful indicators include preventive completion, downtime, repeat incidents and outstanding work.
- Do not close an order merely because the equipment powers on again.
- Attach relevant evidence and test results.
- Record parts and configuration changes.
- Schedule follow-up before returning the asset to routine use.
5. Design continuity for the workflow, not only the device
Ask what happens if the asset is unavailable today. Define who is informed, how appointments are rescheduled, which safe alternative exists, what data must be preserved and which provider is called. Include power, network, workstation, server and cloud outages—not only mechanical failures.
Run short exercises with clinical and administrative staff. A test can verify that the correct order is found, contacts work, a backup restores or the temporary procedure is understandable. Practice reveals hidden dependencies and turns maintenance into operational continuity.
- Reserve equipment or an alternate-care arrangement.
- Power protection and safe shutdown.
- Controlled data access during contingency.
- Patient communication without exposing sensitive information.
- Criteria for returning to normal service.
Frequently asked questions
Questions that should be settled before acting
Does preventive maintenance guarantee equipment will not fail?
No. It reduces avoidable failures, detects deterioration and improves predictability, but it cannot remove every risk. That is why it is combined with inspection, inventory, parts, corrective support and continuity.
Who should define the maintenance frequency?
It should be based on manufacturer recommendations, applicable regulation, risk, use, environment and history. Technical tasks must be assigned to personnel with the required competence and authorization.
Do computers and networking belong in the program?
Yes when they participate in the clinical workflow or affect data availability, integrity or access. Their support must be coordinated with the constraints of the medical device and software.
