The number of surgical implants increases rapidly along with the progression of medical services provided and the Bureau of National Health Insurance (BNHI). Hence, the hospital might be fined by BNHI due to mischarges. To control cost effectively, we set up an efficient way to avoid mischarges by simplifying the charge form, thus shortening the time for registering consumed implants. Our team designed five special forms, including「Form for consumed orthopaedic implants」 and instructions for charging in addition to posting new messages from BNHI. We organized an inspection team to examine the charge records and established regulations for encouragement and discipline. The mistakes related to charging decreased from 47.58% to 3.75% after administrating the new program for 3 months. The number of incorrect charges were reduced from 750 thousand to 60 thousand NTD by the utilization of 「Form for consumed orthopaedic implants」in 3 months. The time required for registration decreased from 8 minutes to 3 minutes. The program enabled nursing personnel to familiarize with the correct way of charging, the regulations of BNHI, and the cost-effectiveness of correct charging. More profit was achieved through the improvement on the charging system.
