Preventive Maintenance of Medical Equipment: A Guide for Fiji Healthcare Facilities

Medical equipment plays an essential role in patient monitoring, diagnosis, treatment, laboratory testing, emergency care, and healthcare delivery.

Hospitals, health centres, clinics, laboratories, dental practices, pharmacies, and community healthcare facilities across Fiji depend on equipment that must operate safely and reliably.

However, medical devices can deteriorate because of repeated use, ageing components, unsuitable storage, accidental damage, electrical problems, transportation, dust, moisture, and environmental conditions.

Fiji’s warm and humid climate, geographical distribution across multiple islands, transportation challenges, and exposure to severe weather can make effective equipment management especially important.

Preventive maintenance is planned servicing performed at predetermined intervals to keep medical equipment in suitable operating condition.

Instead of waiting for equipment to fail, healthcare facilities inspect and service devices before major problems develop.

Preventive maintenance activities may include:

• Visual inspection
• Cleaning
• Functional testing
• Electrical safety checks
• Battery testing
• Lubrication where appropriate
• Replacement of worn components
• Inspection of cables and connectors
• Alarm testing
• Performance verification
• Software or firmware checks
• Calibration where required
• Documentation of completed work

The exact maintenance procedure depends on the equipment type, manufacturer instructions, clinical application, risk level, usage, condition, and service history.

The World Health Organization describes maintenance as an important part of medical-equipment management and provides guidance covering inspection, preventive maintenance, corrective maintenance, inventories, work orders, testing equipment, and technical personnel. WHO Medical Equipment Maintenance Programme Overview

Medical equipment may continue operating even when internal components are beginning to deteriorate.

A device may appear normal while developing problems such as:

• Weak batteries
• Damaged cables
• Loose electrical connections
• Blocked filters
• Worn seals
• Sensor drift
• Reduced alarm volume
• Unstable power supply
• Damaged accessories
• Inaccurate displays
• Mechanical wear
• Software errors

Preventive maintenance provides an opportunity to identify these problems before they result in complete equipment failure.

Regular maintenance can help healthcare facilities:

• Improve equipment reliability
• Reduce unexpected breakdowns
• Support patient and staff safety
• Maintain dependable performance
• Extend useful equipment life
• Reduce emergency repair costs
• Plan equipment downtime
• Maintain organised service records
• Support quality-management procedures
• Identify equipment requiring replacement

Preventive maintenance is particularly important when a facility has limited access to backup equipment or specialist repair services.

Preventive and corrective maintenance serve different purposes.

Preventive maintenance is planned work completed before equipment fails.

Examples include cleaning filters, checking batteries, inspecting cables, testing alarms, and replacing components according to a maintenance schedule.

Corrective maintenance is performed after a fault, breakdown, or performance problem has been identified.

Examples include repairing a damaged power supply, replacing a failed display, correcting an alarm fault, or restoring a device that will not start.

Healthcare facilities need both approaches. However, relying mainly on corrective maintenance can result in:

• Unexpected equipment downtime
• Delayed patient services
• Higher repair costs
• Difficulty obtaining urgent spare parts
• Greater dependence on replacement equipment
• Possible use of unreliable devices
• Reduced equipment life

A preventive approach helps facilities identify manageable problems before they become major failures.

Preventive maintenance and calibration are related but are not the same process.

Preventive maintenance helps maintain the physical and functional condition of equipment through planned inspection, cleaning, servicing, testing, and component replacement.

Calibration compares an instrument’s measurements with an appropriate reference standard to determine whether it is operating within the required accuracy or tolerance.

For example, preventive maintenance of a medical weighing scale may include cleaning, checking the display, inspecting the platform, examining the power supply, and confirming that the controls operate.

Calibration determines whether the scale provides accurate weight measurements.

Completing preventive maintenance does not automatically prove measurement accuracy. Similarly, calibration does not replace the need to inspect, clean, and service the equipment.

Both activities should be coordinated within the facility’s medical-equipment management program.

Most reusable medical equipment can benefit from planned inspection and maintenance.

Examples include:

• Patient monitors
• ECG machines
• Defibrillators
• Infusion and syringe pumps
• Ventilators
• Anaesthesia machines
• Suction equipment
• Pulse oximeters
• Blood pressure monitors
• Medical weighing scales
• Infant incubators
• Radiology and imaging equipment
• Ultrasound machines
• Laboratory analysers
• Centrifuges
• Microscopes
• Autoclaves and sterilisers
• Vaccine refrigerators
• Temperature data loggers
• Dental equipment
• Audiometers
• Examination lights
• Hospital beds
• Oxygen concentrators
• Medical gas equipment
• Electrical safety testing instruments

The maintenance requirements for each device should be based on its intended purpose, manufacturer instructions, risk classification, frequency of use, and operating environment.

There is no single maintenance interval suitable for every medical device.

Some equipment may require monthly or quarterly checks. Other devices may be serviced every six or twelve months.

The appropriate interval depends on:

• Manufacturer recommendations
• Equipment type
• Clinical risk
• Frequency of use
• Age and condition
• Operating environment
• Previous maintenance results
• Failure history
• Availability of backup equipment
• Applicable quality requirements
• Facility procedures

A general maintenance schedule may include:

• Daily checks by equipment users
• Weekly or monthly cleaning and inspection
• Quarterly checks for frequently used or critical equipment
• Six-monthly technical maintenance
• Annual comprehensive preventive maintenance
• Additional servicing following repair, damage, relocation, or unusual performance

These are general examples only. Healthcare facilities should not apply the same interval to every device without considering the equipment’s specific requirements.

Healthcare facilities in Fiji may face equipment-management challenges that differ according to their location and available resources.

Humidity and Moisture

High humidity can contribute to corrosion, condensation, damaged electronic components, and deterioration of cables or connectors.

Equipment should be stored in clean, dry, and well-ventilated areas according to manufacturer requirements.

Transportation Between Locations

Equipment transported between islands, communities, or healthcare facilities may experience vibration, impact, heat, moisture, and handling risks.

Devices should be inspected after transportation before being returned to clinical service.

Power Quality

Voltage fluctuations, outages, unsuitable extension leads, and inadequate power protection can affect electronic medical equipment.

Facilities should use suitable electrical protection and arrange inspection when power-related damage is suspected.

Severe Weather

Cyclones, flooding, heavy rainfall, and other severe weather events may expose equipment to water, humidity, physical impact, contamination, or extended power loss.

Affected equipment should not automatically be returned to service. It may require professional inspection, electrical safety testing, cleaning, repair, calibration, or replacement.

Access to Spare Parts and Technical Support

Some parts or specialist services may need to be sourced from outside the immediate area.

Maintaining essential spare parts and planning services in advance can help reduce extended downtime.

• Use appropriate personal protective equipment
• Decontaminate equipment before servicing
• Notify technicians about possible contamination
• Document decontamination where required

Harsh chemicals or incorrect cleaning methods can damage plastics, displays, seals, adhesives, sensors, and electronic components.

Clinical cleaning and technical maintenance teams should use compatible procedures.

14. Creating a Medical Equipment Inventory

A complete equipment inventory is the foundation of an effective maintenance program.

The inventory should record:

• Equipment name
• Manufacturer
• Model
• Serial number
• Asset number
• Department and location
• Date purchased
• Date installed
• Supplier details
• Warranty status
• Maintenance frequency
• Last service date
• Next service due date
• Calibration requirements
• Risk level
• Current condition
• Repair history
• Responsible person
• Replacement priority

Every device should have a unique identification number.

The inventory should be updated whenever equipment is purchased, transferred, repaired, retired, donated, lost, or disposed of.

15. Assigning Equipment Risk Levels

Risk classification can help facilities determine which equipment requires the highest maintenance priority.

Factors may include:

• Clinical purpose
• Consequences of failure
• Whether the device supports life
• Frequency of use
• Maintenance complexity
• Failure history
• Availability of replacement equipment
• Required accuracy
• Environmental exposure

A simple classification may include:

• High Risk: Equipment where failure could seriously affect patient treatment or safety
• Medium Risk: Equipment where failure could interrupt diagnosis, monitoring, or routine clinical services
• Low Risk: Equipment with limited clinical consequences if temporarily unavailable

Risk classification should be documented and reviewed when equipment use or circumstances change.

16. Developing a Preventive Maintenance Schedule

Healthcare facilities can create a structured schedule through the following process:

Step 1: List All Equipment

Use the equipment inventory to identify every device requiring maintenance.

Step 2: Review Manufacturer Requirements

Check operation manuals, service manuals, technical notices, and warranty conditions.

Step 3: Assign Risk and Priority

Prioritise life-support, emergency, high-use, and high-risk equipment.

Step 4: Define Maintenance Tasks

Identify the inspection, cleaning, testing, calibration, and replacement tasks required for each device.

Step 5: Establish Service Intervals

Set maintenance intervals based on manufacturer instructions, risk, usage, condition, environment, and service history.

Step 6: Assign Responsibility

Identify who will perform daily checks, technical maintenance, calibration, repairs, record management, and schedule monitoring.

Step 7: Plan Equipment Downtime

Arrange backup equipment or schedule maintenance during lower-use periods.

Step 8: Track Due Dates

Use a spreadsheet, calendar, database, equipment-management system, or reminder process.

Step 9: Review Results

Analyse failures, missed maintenance, repeated repairs, out-of-tolerance results, and spare-parts use.

Step 10: Improve the Schedule

Shorten, extend, or modify intervals when supported by equipment performance, risk assessments, manufacturer guidance, and facility requirements.

17. What Should a Maintenance Record Include?

Every maintenance activity should be documented.

A service record may include:

• Equipment identification
• Department and location
• Maintenance date
• Reason for service
• Condition before maintenance
• Inspection findings
• Tests completed
• Results obtained
• Parts replaced
• Repairs completed
• Adjustments made
• Calibration information
• Technician’s name
• Equipment status
• Next maintenance due date
• Recommendations
• Approval for return to service

Records help facilities understand equipment performance and demonstrate that maintenance activities were completed.

They can also support audits, investigations, budgeting, warranty claims, replacement decisions, and future service planning.

18. Managing Equipment That Fails Maintenance

Equipment that fails inspection, safety testing, functional testing, or calibration should not automatically be returned to clinical use.

The facility should:

1. Remove the equipment from service
2. Attach a clear “Do Not Use” label
3. Record the fault
4. Notify the responsible department
5. Arrange technical assessment
6. Repair or replace the equipment
7. Repeat applicable safety and performance tests
8. Document the final decision
9. Authorise return to service only after requirements are met

If repair is not practical or safe, the device may need to be retired.

Facilities should also investigate whether the failure may have affected previous measurements, treatment, or patient care.

19. Spare Parts and Consumables Management

A preventive maintenance program can be delayed when necessary parts are unavailable.

Facilities should identify important items such as:

• Batteries
• Fuses
• Filters
• Power cords
• Sensors
• Probes
• Patient cables
• Tubing
• Seals
• Lamps
• Connectors
• Printer paper
• Approved lubricants
• Cleaning materials

Stock levels should reflect equipment importance, failure history, supplier lead time, storage requirements, and expiry dates.

Parts should be stored correctly and checked before use.

Using unsuitable or unauthorised components may affect equipment safety and performance.

20. Training Healthcare Workers and Equipment Users

Correct use can reduce avoidable equipment damage.

Healthcare workers should receive training covering:

• Equipment start-up and shutdown
• Pre-use inspection
• Alarm interpretation
• Battery charging
• Cleaning and disinfection
• Safe transportation
• Suitable storage
• Fault reporting
• Actions following damage
• Maintenance and calibration labels
• Equipment limitations
• Emergency procedures

Users should not attempt technical repairs unless they are trained and authorised.

Clear reporting can help maintenance personnel respond before a minor issue becomes a major failure.

21. Planning Maintenance Across Fiji’s Islands and Remote Areas

Healthcare facilities outside major centres may need additional planning because technical support, replacement equipment, and spare parts may not be immediately available.

A practical approach may include:

• Grouping maintenance visits by location
• Maintaining accurate equipment lists
• Identifying high-risk equipment in advance
• Carrying commonly required spare parts
• Providing backup equipment during servicing
• Training local staff in approved daily checks
• Using remote technical support where suitable
• Packaging equipment securely for transportation
• Protecting devices from moisture and impact
• Planning services before cyclone seasons or difficult travel periods

Facilities should avoid delaying maintenance simply because equipment continues to switch on.

Functional operation alone does not confirm that a device is safe, accurate, or reliable.

22. When Should Equipment Receive Unscheduled Maintenance?

Equipment should be assessed before its next scheduled service when:

• It has been dropped
• It has been exposed to water or excessive humidity
• It displays an error message
• It produces unusual or inconsistent readings
• An alarm does not operate correctly
• The battery discharges unusually quickly
• A cable, plug, or connector is damaged
• It makes unusual noises
• It overheats
• A user reports a performance problem
• It has been moved or transported
• It has undergone repair
• The manufacturer issues a safety notice
• Its maintenance history is unknown

Questionable equipment should be clearly identified and removed from clinical use until it has been assessed.
