Impact of evidence-based nursing interventions on postoperative recovery and complications after endovascular aneurysm intervention: A retrospective cohort study.

Endovascular aneurysm intervention is increasingly used for aortic and peripheral aneurysmal disease, yet postoperative recovery may be delayed by access-site events, cardiopulmonary instability, symptom burden, and renal vulnerability related to iodinated contrast exposure. This single-center retrospective cohort study evaluated the association between an evidence-based nursing bundle and postoperative outcomes in adults undergoing endovascular aneurysm intervention between January 2024 and December 2025. Patients treated in 2024 received routine perioperative nursing (control, n = 68), whereas those treated in 2025 received a standardized evidence-based nursing program (intervention, n = 69). Baseline demographic, clinical, procedural, and preoperative laboratory characteristics were comparable between groups. The intervention group demonstrated shorter postoperative length of stay (6.04 ± 1.62 vs 7.52 ± 1.91 days; P <.001) and lower intensive care unit admission (11.6% vs 26.5%; P = .026), with reduced ICU duration among admitted patients (median 1.08 vs 2.59 days; P = .013). Recovery milestones occurred earlier in the intervention group, including first ambulation, oral intake, flatus, and defecation (all P ≤ .023). Symptom control improved, with lower Numeric Rating Scale pain scores at 6, 24, and 48 hours (all P <.001) and reduced postoperative nausea and vomiting (14.5% vs 32.4%; P = .013). Any postoperative complication occurred less frequently with evidence-based nursing (17.4% vs 35.3%; P = .017). Postoperative serum creatinine change was smaller (P = .021), while contrast-associated acute kidney injury was numerically lower (P = .097). Evidence-based nursing was associated with accelerated recovery, improved symptom control, and reduced overall complications after endovascular aneurysm intervention.
