We aim to predict the future demand of TKR up to 2015 and provide information for resources allocation and policy making for the National Health Insurance.
1,248,642 cases were retrieved randomly from the National Health Insurance database from 2000 to 2008, constituting 5% of the total cases. 5,311 patients with ICD_OP_CODE 81.54 were analyzed.
Female patients were 2.93 times more than males. TKR cases increased 171% from 2000 to 2008 for people above 50 years old. The largest group was from 60 to 79 years old, occupying 81.6% of TKR cases. The fastest growing group was from 70 to 74 years old with increase of 2,140 cases.
According to demographic projection, population percentage of people above 65 years old will quickly grow form 10.6% in 2009 to 41.6% in 2060. We predict that TKR cases will grow form 17,540 in 2008 to 31,594 in 2015. TKR will be a critical issue and a weighty financial load for Taiwan's national health insurance.
