Choosing an Automated Endoscope Reprocessor for Your Unit

What an AER does and what it does not

An automated endoscope reprocessor irrigates the scope's channels and outer surface with detergent and disinfectant, rinses with water, usually flushes with alcohol and air, and records the cycle. It improves consistency by removing variations in exposure time, concentration and rinsing between operators.

It does not replace manual cleaning. Bedside pre-cleaning, manual brushing and leak testing must happen before the scope enters the machine, as described in our reprocessing steps. Skipping them can leave soil that the machine cannot remove.

Standards and what ISO 15883-4 means

ISO 15883-4 is the part of the washer-disinfector standard that deals with machines for thermolabile endoscopes using chemical disinfection. Ask the supplier for evidence that the model is tested against the standard and for the validation documentation that your hospital will need, including installation, operational and performance qualification.

Local requirements also apply. Confirm current expectations with your accreditation body and the health authority, such as DHA, DOH or MOHAP, and read our overview of reprocessing guidelines and standards.

Technical points to compare

Capacity is the first issue: the number of endoscopes per cycle and the cycle time determine throughput. Check whether the AER has channel connectors for every scope model in your fleet, including bronchoscopes, duodenoscopes, colonoscopes and ENT scopes, and whether an additional connector kit is needed.

Next compare the disinfectant system, water quality requirements, filtration, drying function, cycle documentation and the user interface. Note the footprint, drainage, power supply and ventilation needs of the room.

• Throughput: scopes per cycle and cycle length
• Connector set for your scope models
• Disinfectant type and consumable cost
• Water filtration and quality requirements
• Drying and storage compatibility
• Traceability and printed or digital records

Cost: price, running cost and service

Searching for automated endoscope reprocessor price alone is misleading, because the purchase price is only one component. Running costs include disinfectant, detergent, filters, water treatment, test strips and connectors, plus preventive maintenance and validation visits. Ask suppliers to provide a five-year cost estimate with the same assumptions about cycles per day.

Compare manufacturers on service response, availability of trained engineers in the UAE, spare parts, and training for staff, not just on machine specification. Evaluate also whether you need one or two machines to keep a unit running when one is under service.

Validation, maintenance and staff training

After installation the machine should be qualified and its performance verified before clinical use, and then re-verified at intervals defined by your infection-control policy and the manufacturer. Typical checks include water quality, disinfectant concentration monitoring, filter replacement and microbiological sampling of rinse water and scopes as your policy requires.

Plan maintenance with the supplier, including who changes filters, who calibrates sensors and how quickly a service engineer can reach you. Train every user on loading, connector selection, alarms and recovery from an aborted cycle, and record the training. Many reprocessing incidents arise from wrong connectors or interrupted cycles rather than from machine failure; our guide to endoscope reprocessing certification describes training paths for staff.

Planning the room and next steps

A reprocessing room needs a clear workflow from dirty to clean, with sinks for manual cleaning, space for the AER, and drying and storage cabinets. Consider ventilation for chemical vapours and how scopes move between areas. See flexible endoscope storage for the end of the cycle and the endoscopy suite equipment checklist for the wider plan.
