Michigan Hospitals Revolutionize Aortic Care with Follow-Up Imaging
A groundbreaking collaboration is transforming aortic aneurysm treatment in Michigan, with a dramatic increase in follow-up scans that significantly reduce patient risk. This initiative, involving a statewide hospital alliance, has led to a remarkable improvement in patient care and outcomes.
The study reveals that the number of patients receiving follow-up imaging after aortic aneurysm repair has skyrocketed. In 2017, only 28% of patients underwent imaging within a year of endovascular aneurysm repair (EVAR). But by 2023, this figure soared to an impressive 80%.
And here's the most striking part: patients who had these follow-up scans were 60% less likely to die within a year of surgery, even when considering other health conditions. This is a massive leap forward in patient care, as the study highlights a critical gap in post-operative care that could save countless lives.
Dr. Frank M. Davis, the lead author and vascular surgeon, emphasizes the importance of this finding, stating that nearly 57% of patients were previously missing these crucial follow-up scans. The collaboration has enabled healthcare providers to identify early issues that could lead to device failure or life-threatening complications, such as aortic rupture.
The Society for Vascular Surgeons recommends annual CT scans or ultrasounds for life after EVAR. The initiative, facilitated by the Blue Cross Blue Shield of Michigan Cardiovascular Consortium (BMC2), offered financial incentives to encourage hospitals to implement this surveillance imaging.
Over 30 hospitals joined the effort, and the results were remarkable. The BMC2 registry, based at Michigan Medicine, collects data from hospitals across the state to enhance quality projects and patient outcomes. Before the study, EVAR surveillance imaging rates varied widely, with smaller hospitals at 3.7% and larger facilities at 62.5%.
But the initiative's success wasn't limited to large hospitals. By 2023, 95% of participating hospitals achieved EVAR surveillance rates above 60%. Dr. Nicholas Osborne, senior author and research professor, attributes this success to identifying sustainable processes at each hospital, making it easier for healthcare teams to maintain the program.
Abdominal aortic aneurysm affects approximately 200,000 Americans annually. Studies show that 14% of EVAR patients require a second procedure within 4-5 years, and less than 2% experience late aortic rupture. Interestingly, patients with surveillance imaging during the study had more repeat interventions but significantly lower mortality rates.
But here's where it gets controversial: past studies have conflicting results regarding the association between follow-up imaging and reduced mortality after EVAR. This study's authors plan to delve deeper, using BMC2 data to investigate mortality risks after 5 and 10 years of surveillance.
Dr. Davis highlights the impact of BMC2, stating that implementing quality programs across Michigan has led to substantial improvements in care, especially for aortic surgery patients. The study's findings are published in Circulation: Population Health and Outcomes, and the authors are eager to share their insights with the medical community.
