Prioritize Medical Equipment Replacement Using Analytical Hierarchy Process

Clinical Engineering Department in hospitals need to take decision for Health Care Technology assessment which includes purchase, maintenance, use, and replacement. In this paper we proposed a analytical hierarchy processes -group decision making (AHP-GDM) model to prioritize the medical equipment for replacement. The model structure includes 11 quantitative and qualitative factors descending as main and sub criteria which can affect of the replacement decision. Each device should be assessed with respect to every covering criterion .and the devices ranking with respect to the criteria independent of other devices . the final score for each devices was calculated as replacement priority index(RPI) . the model was applied for 30 devices in ICU where devices with higher RPI take a higher priority for replacement according for available budget in hospital and Devices with lower RPI take a lower priority for replacement. This model can be integrated as an automated system for medical devices replacement in health care facilities.
