Purpose of this study is a retrospective study to compare the cost-effectiveness of anterior cervical discectomy and fusion(ACDF) and cervical disc replacement(CDR). ACDF and CDR are the way of surgery for patients who have a degenerative cervical disc disease and need surgery for treatment. ACDF is traditional way of surgery on the other hand CDR is more expensive and new way for degenerative cervical disc disease.
Subjects of this study are the patient who 30 to 59 years old and get ACDF and CDR surgery with a degenerative cervical disc disease from January 01, 2008 to December 31, 2009 in hospital located in Seoul, Korea, which has 2000 over bed in order to compute transitional probability of Marcov decision model and cost which used on cost-effectiveness analysis.
Methods We carried out cost-effectiveness analysis using QALY(Quality adjusted life year) as a result an indicator of patients undergoing surgery, using Marcov decision model as a model for analysis. Medical expenses required for the analysis of cost-effectiveness, only medical expenses are included and non-medical expenses are excepted. Data analysis was used Treeage Pro2015Tm.
Results The patients who get ACDF paid 2,501,807 won and got 3.72QALY during 5 years. The patients who get CDR paid 3,685,949 won and got 4.18QALY during 5 years. Comparing with ACDF, incremental cost-effectiveness ratio(ICER) of CDR was found to be 2,549,511 won/QALY. This is the results of less than about 30 million won/QALY is a common willingness to pay criteria of Korea. This result can be regarded as both of ACDF and CDR are cost-effective alternative for patient with degenerative disc disease. Also CDR is more cost-effective alternative comparing ACDF if patient wants get more utility by additional cost.
