Three numbers decide how a hospital should organise equipment service: the annual cost of the service contracts, the cost of a day of downtime for the device class, and the value of the parts a technician would have to hold to cut the repair time. Everything else in service management — dashboards, sensors, outsourcing — […]

The list is cancelled at 07:40 because the tower will not power on. The biomedical engineer confirms the fault in ten minutes, the parts are not in the building, and the question that decides the next three days is not technical at all: who is contracted to attend, and on what response time. Hospitals rarely

Two ventilators of the same model, installed the same month, in the same hospital. One is serviced on the calendar and fails on a Sunday; the other is serviced on the calendar and is pulled from service three weeks early because its turbine current draw has been drifting since February. The devices are identical. What

An inspection certificate proves something narrower than most buyers assume. It evidence that a device met defined criteria at a particular moment, checked by a particular method — not that the unit is sound today, and not that the paperwork describes the unit in front of you. The certificate is the start of verification, and

Two hospitals run the same imaging fleet and report the same maintenance budget. One replaces transducers on a two-year cycle because that is what the spreadsheet says; the other replaces them when the calibration trend says the element is drifting. Same spend on paper, very different uptime — because one schedule is a calendar and

An infusion pump that drifts four percent low does not announce itself. It delivers, the nurse charts the dose, and the error surfaces days later as a clinical picture that does not match the prescription. Preventive maintenance exists for that failure mode rather than for the dramatic one, because the devices that stop working are

There are seven steps in a medical device procurement process, and only one of them is about price. The other six exist because a device has to be justified clinically, funded, verified as marketable, sourced, contracted, received and then kept working — and a process that skips any of them moves the cost to a

The counter-intuitive part of a hospital device procurement checklist is that the last item matters more than the first. Needs assessment gets the attention because it is where clinicians argue about specifications, but the checklist only succeeds or fails at commissioning, when somebody has to decide whether the thing that arrived may lawfully be used.
