- Open in new tab Download slide 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. [ABSTRACT FROM AUTHOR]
