Medical Equipment Maintenance: How to Develop Maintenance Plans, Frequencies, and Records

When Does a Medical Equipment Maintenance System Need Review?

- Equipment is inspected only after a fault occurs.

- Many devices are overdue for maintenance without any alert mechanism.

- The same fault recurs after repairs.

- User departments do not know whom to contact when equipment malfunctions.

- Records simply state “maintenance completed” without specifying the work performed.

- The technical department's equipment inventory does not match the equipment actually in use.

- Warranty contracts have expired without a follow-up maintenance plan.

- Equipment remains out of service for extended periods while waiting for spare parts.

- Departments contact suppliers independently without updating the central management unit.

- Repair costs are not tracked by individual device.

In these situations, simply increasing maintenance frequency may not resolve the underlying problems. Healthcare facilities need to review the entire process, from the equipment inventory and priority classification to work assignment and recordkeeping.

Distinguishing Preventive Maintenance, Repair, and Equipment Inspection

A medical equipment maintenance program typically includes more than one type of activity. WHO describes maintenance strategies as including inspection, preventive maintenance, and corrective maintenance. Performance inspection helps confirm that equipment is functioning properly; safety inspection focuses on safety for patients and operators; while preventive maintenance is intended to extend service life and reduce the risk of failure.

Activity	Primary Purpose	When It Is Performed
Pre-use inspection	Identify readily observable abnormalities	Before each use or according to departmental procedures
Functional inspection	Assess the basic functions of the equipment	According to schedule or after technical intervention
Safety inspection	Identify issues that may affect users or patients	According to technical requirements and risk level
Preventive maintenance	Clean, adjust, inspect, and replace components according to plan	Before equipment failure occurs
Corrective maintenance	Correct faults that have already occurred	When equipment is not operating properly
Inspection	Assess safety and technical performance within the applicable scope	According to requirements applicable to the equipment
Calibration	Determine and control the accuracy of measurement functions	According to technical or quality system requirements

Building a Maintenance Plan from the Actual Equipment Inventory

A maintenance plan should not begin by opening a calendar and selecting dates. The starting point should be the actual inventory of equipment managed by the facility.

Step 1: Standardize the Equipment Inventory

Each device should include at least the following information:

- Equipment ID.

- Equipment name.

- Manufacturer.

- Model.

- Serial number.

- Commissioning date.

- Department or location of use.

- Responsible person or unit.

- Operational status.

- Warranty period.

- Supplier or maintenance service provider.

- Current maintenance frequency.

- Most recent maintenance date.

- Expected next maintenance date.

Step 2: Collect Technical Documentation

Before establishing maintenance scope and frequency, facilities should collect:

- Instructions for use.

- Manufacturer maintenance instructions.

- Service manuals, if provided.

- Lists of regularly replaced parts.

- Environmental operating requirements.

- Power, gas, water, or connectivity requirements.

- Software update recommendations.

- Safety alert information.

- Warranty terms.

- Supplier scope of work.

Step 3: Classify Equipment by Priority

Not all equipment needs to be managed with the same level of priority. Facilities may develop an internal rating system based on factors such as:

- Impact if the equipment becomes unavailable.

- Role in diagnosis, treatment, or monitoring.

- Level of patient contact.

- Potential risk if the equipment functions incorrectly.

- Frequency of use.

- Environmental conditions.

- Availability of alternative equipment.

- Spare part lead times.

- Incident history.

- Repair costs.

- Manufacturer requirements and relevant regulations.

For example, equipment used in intensive care, surgery, or continuous monitoring will generally require a different level of priority from equipment that is rarely used and has multiple substitutes available. However, the specific priority level should be assessed according to the actual role of the equipment within each facility.

Step 4: Define the Work to Be Performed

- Visual inspection.

- Cleaning of technical components.

- Inspection of power cables, connectors, and accessories.

- Inspection of batteries or backup power sources.

- Inspection of fans, filters, and cooling systems.

- Inspection of moving mechanisms.

- Alarm testing.

- Measurement function testing.

- Data connectivity checks.

- Configuration backup.

- Software updates according to instructions.

- Replacement of wear parts.

- Electrical safety testing where appropriate.

- Trial operation and confirmation of equipment status after maintenance.

Step 5: Determine Who Will Perform the Work

Depending on complexity, maintenance activities may be carried out by:

- Departmental users.

- Hospital technical staff.

- Biomedical engineers.

- Suppliers.

- Warranty service providers.

- Technical service companies.

- Appropriate inspection or calibration service providers.

- Professional competency.

- Tools and measurement equipment.

- Access to technical documentation.

- Service software or passwords.

- Warranty scope.

- Manufacturer requirements.

- Relevant legal responsibilities.

- Ability to provide reports and test results.

Personnel who have not received appropriate training should not dismantle or adjust components that may affect equipment safety or functionality.

Step 6: Schedule Maintenance and Estimate Resources

The maintenance plan should specify:

- Equipment list.

- Scope of work.

- Frequency.

- Planned month or date.

- Person responsible.

- Required equipment downtime.

- User department.

- Spare parts and supplies to prepare.

- Estimated cost.

- Alternative equipment arrangements during downtime.

- Completion status.

Maintenance schedules should be coordinated with user departments to minimize disruption to clinical activities. For equipment with high utilization, hospitals may need to perform maintenance outside normal hours, arrange backup equipment, or divide the work into multiple stages.

How Should Medical Equipment Maintenance Frequency Be Determined?

Manufacturer Instructions

Manufacturer guidance is typically the first reference point when establishing a maintenance plan. Manufacturers may specify:

- Time-based maintenance intervals.

- Maintenance intervals based on operating hours.

- Maintenance intervals based on number of uses.

- Components requiring scheduled replacement.

- Conditions that need to be inspected.

- Scope of work for users and technicians.

If a facility changes the maintenance frequency from the manufacturer's recommendation, an appropriate assessment, approval process, and supporting rationale should be documented.

Actual Utilization

- Operating hours.

- Number of uses.

- Number of cycles.

- Number of start-ups.

- Sample volume.

- Number of transfers or movements.

- Accessory utilization.

For equipment with operating counters, the maintenance plan should consider both time intervals and actual utilization.

Failure History

- Number of failures per year.

- Average interval between failures.

- Whether faults recur.

- Components that frequently require replacement.

- Whether causes are related to operation or environmental conditions.

- Downtime.

- Repair costs.

- Equipment condition after each maintenance activity.

If the same fault recurs within a short period, simply increasing maintenance frequency may not be enough. Hospitals should assess repair quality, operating conditions, user competency, and whether equipment replacement should be considered.

Environmental Conditions

- Temperature.

- Humidity.

- Dust.

- Vibration.

- Power supply.

- Grounding.

- Ventilation.

- Water quality.

- Medical gases.

- Chemicals.

- Cleaning and disinfection frequency.

Equipment maintenance may remain ineffective if the underlying cause of faults is related to infrastructure and that issue is not addressed.

Importance to Clinical Operations

Priority Level	Reference Characteristics	Management Approach
High	Critical equipment, high utilization, limited alternatives	Close monitoring, early alerts, spare part preparation, and backup arrangements
Medium	Affects workflows but alternative equipment can be arranged	Scheduled maintenance and monitoring of fault history
Low	Limited use, easy to replace, relatively low operational impact	Inspection according to instructions and actual condition

This matrix does not replace manufacturer requirements or legal regulations. It is intended only to support allocation of personnel and budgets.

How Should an Annual Maintenance Plan Be Structured?

Instead of maintaining only a list of dates, hospitals can organize maintenance planning into three levels.

Annual Master Plan

The annual plan helps management review:

- Total number of devices requiring maintenance.

- Distribution of work by month.

- Outsourced service requirements.

- Estimated budget.

- Contracts approaching expiration.

- Periods with high workloads.

- Priority equipment groups.

Detailed Monthly Plan

The monthly plan should provide more specific information:

- Equipment ID.

- User department.

- Planned date.

- Technician.

- Supplier.

- Expected downtime.

- Spare parts to prepare.

- Schedule confirmation status.

- Completion results.

Work Order for Each Device

1. Equipment identification information.

2. Type of work.

3. Reason for performing the work.

4. Technical checklist.

5. Tools and measurement equipment used.

6. Parts replaced.

7. Results before and after maintenance.

8. Outstanding issues.

9. Recommendations.

10. Person performing the work and person confirming completion.

11. Next maintenance date.

What Should Medical Equipment Maintenance Records Include?

Record Category	Information to Track
Plan	Equipment list, schedule, resources, and budget
Work order	Equipment, work scope, responsible person, and deadline
Technical checklist	Inspection steps and results
Maintenance report	Work performed, parts replaced, and post-maintenance condition
Abnormality report	Faults identified, potential impact, and recommended action
Spare part documentation	Part number, source, and replacement date
Test results	Parameters before and after maintenance where required
Equipment history	All maintenance, repairs, and status changes
Costs	Labor, services, spare parts, and equipment downtime
Handover confirmation	Trial operation results and return to the user department

- “Machine checked.”

- “Equipment cleaned.”

- “Machine operating well.”

- “Resolved.”

08/VBHN-BYT dated March 6, 2026, on medical device management.

Which Indicators Can Be Used to Monitor Maintenance Effectiveness?

- Percentage of maintenance tasks completed on time.

- Number of devices with overdue maintenance.

- Percentage of equipment available for operation.

- Number of failures by equipment category.

- Rate of recurring faults.

- Response time to repair requests.

- Average repair time.

- Total equipment downtime.

- Maintenance and repair costs.

- Cost per operating hour.

- Number of devices awaiting spare parts.

- Percentage of outsourced work.

- Number of abnormalities identified during preventive maintenance.

- Percentage of records containing complete results and confirmation.

The same threshold should not be applied to every equipment group. Indicators should be analyzed according to criticality, equipment age, frequency of use, and operating conditions.

When Should Maintenance Management Software Be Used?

Spreadsheets may be suitable for facilities with a small number of devices and relatively simple processes. However, when hospitals operate across multiple departments or locations and manage different service contracts, using separate files can lead to:

- Duplicate equipment IDs.

- Uncertainty over which version is current.

- Missed maintenance schedules.

- Inability to retain change histories.

- Difficulty linking fault reports to individual devices.

- Difficulty consolidating costs.

- Difficulty managing user permissions.

- Difficulty tracking work status in real time.

- Centralized equipment inventory.

- QR codes or barcodes.

- Due-date alerts.

- Electronic fault reports.

- Work orders.

- Spare part management.

- Maintenance and repair history.

- Contract management.

- Cost tracking.

- User access control.

- Audit logs.

- Performance reporting.

- Data export capabilities.

- Backup mechanisms.

- Integration capabilities with other systems where necessary.

Software cannot replace technical procedures or professional competency. If the initial equipment inventory is inaccurate and users do not update completed work, the system will still produce unreliable data.

Common Mistakes That Make Maintenance Plans Less Effective

Scheduling by Habit Rather Than by Equipment Needs

Using one fixed frequency for all equipment makes planning easier but does not accurately reflect differences in risk and utilization.

Focusing Only on Equipment Still Under Warranty

Equipment still requires maintenance after the warranty expires. Facilities need to determine who will provide maintenance, where spare parts will come from, and what budget will be required.

Failing to Coordinate with User Departments

If a maintenance schedule is developed without consultation with the user department, work may be repeatedly postponed because the equipment is still being used for patient care.

Failing to Prepare Spare Parts Before Equipment Is Taken Out of Service

If a device is dismantled for maintenance and spare parts are not available, downtime may be unnecessarily prolonged.

Failing to Evaluate Recurring Faults

Repeated faults may indicate problems related to spare parts, operating conditions, user practices, repair quality, or equipment age.

Failing to Record Equipment Downtime

If hospitals track repair expenses but not downtime, they may overlook the operational impact of disruptions to clinical activities.

Failing to Perform Post-Maintenance Checks

Equipment should be tested and confirmed as suitable before being returned to use. Completing a checklist does not automatically mean the equipment is ready for operation.

Frequently Asked Questions About Medical Equipment Maintenance

How Often Should Medical Equipment Be Maintained?

Frequency depends on manufacturer instructions, risk level, operating hours, environmental conditions, failure history, and applicable requirements. A single schedule should not be applied to every device.

Can Equipment Be Repaired Only When It Fails?

This approach may be appropriate for some low-impact equipment that is easy to replace. For critical equipment, relying solely on corrective repair may increase the risk of operational disruption. Facilities should assess the approach by equipment category.

Can User Departments Maintain Equipment Themselves?

User departments may perform checks, cleaning, and routine care specified in the instructions. More specialized technical work should be performed by personnel with appropriate competency and responsibility.

Can Maintenance and Calibration Be Performed at the Same Time?

They may be scheduled during the same service visit if the service provider is qualified to perform both activities and each is documented separately. However, a maintenance report should not be used as a substitute for calibration results.

Does Equipment That Is Operating Normally Still Need Maintenance?

It may still require maintenance. Preventive maintenance is intended to detect and address issues before obvious failure occurs. Scope and frequency should be based on technical guidance and facility assessment.

How Long Should Maintenance Records Be Retained?
