OBJECTIVES: In Taiwan, endovascular aneurysm repair for treating abdominal aortic aneurysms (AAA) was introduced in 2004 and became reimbursable in February 2010. We evaluated the real-world practice and safety of endovascular aneurysm repair in Taiwan.
METHODS: Patients who underwent repair operations for AAA (open or endovascular) from 2000 to 2016 were enrolled (n = 11485). Outcome statistics (during the index hospitalization: length of stay, rate of ischaemic bowel disease and 30-day mortality; after discharge: 30-day readmission rate, 2-year mortality, 2-year reintervention rate and 2-year paraplegia rate) were calculated for each half-year cohort. Propensity score-based stabilized weights were used to balance covariates among each half-year cohort. Interrupted time-series analysis was then performed.
RESULTS: The elective and emergency ratio of AAA repair was 50:50 from 2000 to 2004 and became 60:40 from 2010 to 2016. The half-year rate of endovascular aneurysm repair was 0% in 2000 to 2004/06, 83.16% in 2010 and 98.1% in 2016. Interrupted time series analysis revealed that after endovascular aneurysm repair became reimbursable, both elective and emergency groups had a reduction in length of stay (-4.2 days, P < 0.0001; -1.5 days, P = 0.0928) and 30-day mortality (-5.22%, P = 0.0702; -7.76%, P = 0.0086) but a significant increase in the reintervention rate (5.05%, P = 0.0031; 4.36%, P = 0.0097).
CONCLUSIONS: Endovascular aneurysm repair was predominantly used in treating AAAs after it was reimbursed in Taiwan. Endovascular aneurysm repair is efficacious regarding short-term outcomes but increased the 2-year reintervention rate in both groups.
