10. 2 4 First the registration of individual equipment is carried out through survey and based on this a list of equipment is made From this inventory an inspection schedule is made and implemented accordingly When some faults are found during an inspection preventive repair is carried out During inspection and preventive repair equipment utilisation safety performance and spare parts consumption are monitored At the same time it is important that one protects oneself from infection by following the infection prevention rules of the hospital At the end of the fiscal year it is necessary to carry out an estimation of necessary consumables calculation of EURs summation of operational costs revising the list as well as planning for the coming year An updated report is submitted to the hospital authority When the inspection part of the maintenance cycle management begins it is important to do away with all the breakdown and malfunction cases During the process of survey and registration all inoperative medical equipment must be found Clearly indicate reasons as to why the equipment is inoperative and attempt to find solutions as shown in Table 2 2 In NMCHC for example 170 pieces of medical equipment were in use as of 1998 However a lot of equipment had faced various problems because maintenance had not been carried out since 1993 Random failure occupied only a few cases among these failure cases while others had been caused by m

12. ME section On the other hand the problem is that the hospital establishes the ME section with staff whose level of ability is in the repair of home appliances As a result the working condition of medical equipment is determined by either functioning or not functioning in the range of the repair technique they are familiar with The concept of maintaining safety and reliability through regular inspection is overlooked Even if a repair technician completed the repair of an anaesthesia apparatus for example he is not able to evaluate its reliability and safety NMCHC established a maintenance group comprising two anaesthetic nurses and an anaesthetic doctor to address the above mentioned problem They continued making efforts to monitor the safety and reliability of medical equipment and surgical facilities in the operating theatre As a result of these daily inspections problems were solved by working together with the ME section and Facility Maintenance Section 2 The person in charge of the medical equipment service of the ME section Part Two Basic Maintenance and Management of Medical Equipment 45 who was inclined to the exclusive use of electronic equipment was replaced by a former anaesthetic nurse who was interested in medical equipment technology and has a clinical background This resulted in the service of both maintenance and management technology improving and the hospital has recognised the services of the ME sect

Part Two Basic Maintenance and Management of Medical Equipment Part Two Basic Maintenance and Management of Medical Equipment 35 36 Part Two Basic Maintenance and Management of Medical Equipment Part Two Basic Maintenance and Management of Medical Equipment Introduction Medical equipment management is generally focused on how engineers and technicians deal with repair work and its development However many failure cases called breakdowns are caused by inadequate maintenance as described in Part 1 This indicates that the capability to manage medical equipment remains rather weak as follows Equipment utilisation and the deterioration of consumable components including accessories are not being monitored through regular inspection e The deteriorated consumable components are not being replaced on a regular or appropriate basis e Material management that estimates necessary kinds and quantities of consumable components and catries out procurement inventory control and supply for these is not being done properly From the above discussion it should be evident that the focus should not only apply to repair systems and abilities but also to personnel involved in management systems of equipment and materials and those in technical and general administration Maintenance and management skills are therefore given a priority in training the engineer and technician In addition it is necessary to disseminate and enligh

17. contracts that the equipment manufacturer or agency offers are required In some cases AMCs or spot contracts are needed even for general medical equipment to ensure performance safety and reliability AMCs have the following examples of contracts e Complete maintenance including repair in accordance with manufacturer s technical standard includes small amount of consumables free of charge but the customer must bear the cost of expensive consumables e Performing functional inspection and maintaining performance and safety by regular visits includes small amount of consumables free of charge but the customer must bear the cost of expensive consumables on call repair service is charged e Maintenance execution of content based on mutual agreement with customer by regular visits customer bears the cost of all consumables on call repair service is charged Selection of conditions to achieve maximum effectiveness by the least cost is however very difficult In addition cases where maintenance and inspection are properly carried out by agency are rarely fulfilled in accordance with contract terms The hospital authorities often assume and hope for the following the contracted out equipment does not break down and accomplishes its lifespan without any defects since AMC or contracted out service is in place It is unfortunately rare that this expectation is realised It is for this reason that the hospital should at least monitor the

31. iven below 2 1 1 Acquisition Planning It is essential to develop an acquisition plan in order to promote rational equipment acquisition and sustainable utilisation of equipment In most countries standardised procurement procedures for general materials and equipment are already developed however establishment of a reasonable system for procurement of medical equipment is rarely done For instance the section head or the hospital director and supplier often go ahead with selection and procurement of medical equipment in the absence of a contribution of the ME section The fact is that the importance of the ME section its 4 Note 2 3 evaluation and trust are not recognised The acquisition planning process should be consultative and participatory and should involve all stakeholders and the MEMC of the health facility In addition the acquisition plan must consider the finances and human resources involved to sustain proper utilisation and maintenance of the medical equipment In the planning process necessary medical equipment and hospital laboratory equipment for clinical application are carefully discussed regarding needs purpose specification performance safety price benefit to patient etc The plan is supported by feasibility studies capacity assessment appraisal of physical environmental requirements life cycle cost and cost benefit analysis The decision making process should be informed by various assessments as
