Aortic & peripheral vascular disease
Association Between Creation of an Endovascular Aortic Aneurysm Surveillance Program and 1-Year Follow-Up and Mortality in the State of Michigan, United States
Authors' conclusion
Incomplete imaging surveillance following EVAR remains high and predisposes patients to worse outcomes. Utilization of a surveillance program with an associated financial incentive, is a viable strategy that can have a significant impact on increasing EVAR surveillance and decreasing 1-year mortality after EVAR.
Study context
- Population
- Patients who underwent EVAR between 2017 and 2023 in the state of Michigan, United Statespatients who underwent EVAR between 2017 and 2023, mean age 72.6 years, 81% male
- Participants
- 5,583 patients
- Exposure
- Presence or absence of EVAR surveillance imaging; change in surveillance following implementation of the EVAR surveillance program
- Outcome
- Completion of EVAR surveillance and the longitudinal change in the percent of EVARs that obtained surveillance imaging following implementation of the EVAR surveillance program
- Follow-up
- 1 year
Methodological details36 hospitals, Covariate-adjusted Bayesian logistic models
