Abstract：Objective To establish estimation method on budget management of medical device spare parts and to evaluate the
cost of medical device spare parts in the tertiary general hospital. Methods While this evaluation was performed, the relationship
between paid cost for spare parts according to technological development level of device groups and total inventory value was
used. Spare part cost analysis was carried out by using the weighted average method. Results From 2015 to 2018, the cost ratios
were acquired for high, middle, low and simple technology group as 17.31%-33.48%, 32.80%-43.36%, 24.29%-30.97% and
9.43%-11.89%, respectively. The ratio between the spare part and total inventory costs was calculated as 2.62%, 3.52%, 3.14% and
4.69%, respectively. Expected rates based on normalized weighted method were obtained as follows, 4.35%, 4.88%, 5.32% and
4.27%. Conclusion The expenditure analysis and budget planning for medical device spare parts could be predicted more accurately
by taking into consideration the expected rate calculated by the weighted average method. In addition, the importance of Clinical
Engineering Service Units in management of medical devices has been determined.
