Consumable Lock-In: When the Device Is Cheap and the Consumables Are Not

Equipment acquisition and equipment cost are different numbers, and consumable-dependent devices are where the gap between them is widest. A platform can be offered at a price that compares well against alternatives while the items it consumes each time it is used determine what the programme actually costs. The exposure is not visible in a

Competency Records and Training Evidence for Equipment Servicing

A department that cannot show who was competent to perform a task cannot demonstrate that the task was performed competently, and the two are routinely assumed to be the same thing. Competence is a specific property: a technician trained on one platform is not thereby competent on another, and a person who has attended a

Cleaning Verification and Residual Testing for Reusable Instruments

Cleaning is the step that sterilization cannot compensate for, and it is the step that is hardest to see. A sterilizer that achieves its cycle conditions on a load that still carries soil will produce a load that is sterile and still contaminated, and nothing in the sterilization record reveals the difference. Cleaning verification exists

Temperature, Humidity and Shock Limits in Medical Equipment Transport

A unit that leaves a facility within specification and arrives with a cracked detector panel, a fogged optical path or a gel that has separated rarely fails because somebody ignored the equipment. It fails because the environmental limits that applied during transport were never written down, so nobody could tell whether the crate stayed inside

MRI Sourcing: Magnet, Cryogen and Site Requirements

MRI is the imaging modality where the site determines the purchase more than in any other. The magnet’s field imposes constraints on the room, the surrounding spaces and the building’s contents, and the cryogenic system imposes requirements on services, access and ongoing supply. A used MRI system can be a sound acquisition and an unbuildable
