Maintenance of medical equipment generally falls into two categories: preventive maintenance and corrective maintenance. Preventive maintenance consists of scheduled actions designed to extend device life and reduce the likelihood of failure through activities such as calibration, part replacement, lubrication, and cleaning. Corrective maintenance refers to the work required to restore a device to proper working order after a fault or malfunction has been identified.
In practice, hospital equipment maintenance strategies often drift toward two extremes. At one end, devices are serviced only after performance has already deteriorated or the device has stopped functioning altogether. At the other, components are replaced too broadly as a precaution, even when there is no clear technical reason to do so. Neither approach typically delivers the best long-term outcome. The most effective way to control lifecycle costs is through an analytical maintenance model in which decisions are guided by fault diagnostics, usage history, risk assessment, and lifecycle management.
Overly broad maintenance can increase costs without adding value
Excessive repair work rarely appears as a single major error. More often, it results from a series of small decisions that gradually drive up total cost. A common example is the preventive replacement of components that are still functioning properly, without clear evidence that replacement will improve performance or reduce meaningful risk. Another is a standardized repair approach in which multiple parts are routinely replaced regardless of their actual condition.
That approach may seem safe, but in practice it can increase maintenance spend and raise lifecycle costs without providing a corresponding benefit. As AAMI has noted in discussion around optimizing preventive maintenance programs, maintenance activities should be assessed critically based on whether they genuinely improve safety, reliability, and usability rather than being carried out simply because they have always been part of the routine.
A purely reactive approach often becomes more expensive
The other extreme is reactive maintenance, where action is taken only after a fault has already disrupted use or taken the device out of service. In the short term, this can look economical because no work is done in advance and no parts are replaced unnecessarily. In reality, the risk is simply deferred, and it often grows over time.
WHO describes maintenance as a way to extend equipment life and reduce failure rates. Inadequate maintenance, increases downtime, weakens performance, and consumes both money and resources. A reactive strategy may lower maintenance spend in the moment, but it can raise total lifecycle cost through longer downtime, more extensive failures, and maintenance needs that are harder to anticipate and manage.
A balanced maintenance model delivers the greatest savings
The best outcome rarely comes from extremes. Excessive caution increases costs when functioning parts are replaced without clear justification. Excessive delay, on the other hand, increases risk when issues are addressed only after they have already progressed.
A balanced maintenance model brings together three things: accurate diagnostics, experience- and data-based decision-making, and targeted actions. In this way, maintenance is not done too much or too little, but exactly to the extent required for safe, cost-effective, and long-term use of the device.
Our maintenance strategy is based on the full lifecycle cost and usability of the device
An individual repair may appear inexpensive, but that alone does not show whether the solution was right from the perspective of the whole. More important questions are how often the device is out of use, how many repair cycles it goes through, how predictable the maintenance need is, and how long the device remains safe to use. The goal of the maintenance strategy is not to minimize the price of an individual repair, but to optimize the total lifecycle cost and usability of the device.
Identifying the right maintenance timing is not based on guesswork, but on systematic monitoring. The assessment draws on factors such as the device’s usage history, recurring fault types, the results of leak testing and inspection methods, and the level of use. Based on this information, it is possible to determine when maintenance is economically justified, when the device can still be kept safely in use, and when a preventive action will reduce overall risk. At the same time, decision-making becomes more structured and less random.
Health Traders’ service process: diagnostics first
Health Traders’ approach is based on making maintenance decisions with diagnostics first. The repair process begins with a detailed technical assessment in which the device is analyzed individually. After that, the actual fault location and the extent of the damage are evaluated before any service recommendation is made. Based on the technical assessment, the right actions can be identified at the right time, making cost-effective maintenance possible.
The next step is to create a targeted repair plan. We repair the actual damage, but we do not replace functioning components without a clear technical reason. When needed, we also recommend preventive actions, but these are not based on assumption-driven caution. Our recommendations are based on experience with similar damage development, typical wear patterns, and risk analysis of how the device is used.
Our maintenance strategy helps identify damage development at an early stage, make timely service recommendations, avoid unnecessary part replacements, and find a balanced solution between risk and cost. This is based on the decades of experience our technicians have in repair processes and the understanding they have built over time of how different faults typically develop in practice. The goal is not to maximize the billing of an individual service event, but to keep total costs under control over the long term.
Summary: lifecycle thinking creates cost savings
Lifecycle thinking helps identify where the real costs of hospital equipment come from. The price of a single repair tells only part of the story, because what also matters is downtime, recurring maintenance needs, the remaining service life of the device, and the predictability of the maintenance budget.
The greatest savings are achieved when maintenance is neither excessive nor insufficient. Excessive caution raises costs when functioning parts are replaced without a clear reason. Excessive delay increases risk when problems are addressed only after they have expanded. The best outcome is achieved through accurate diagnostics, experience-based decision-making, targeted repairs, and long-term lifecycle thinking. A maintenance model like this helps control total costs, extend device life, and support safe and predictable use.
