Abstract: OBJECTIVE To explore the effectiveness of evidence-based nursing in recovery of abdominal aortic aneurysm patients at risk of infection following stent implantation. METHODS A total of 57 patients with abdominal aortic aneurysm who received stent implantation and tended to have postoperative infections in department of vascular surgery of The First Medical Center of Chine PLA General Hospital from Oct. 2022 to Oct. 2025 were recruited as the research subjects. The enrolled patients were divided into the conventional nursing group with 30 cases and the evidence-based nursing group with 27 cases according to the postoperative nursing mode. The baseline data were compared between the two groups of patients. Weighted logistic analysis was performed to analyze the effectiveness of the evidence-based nursing in recovery of postoperative tendency to infection. RESULTS The rat of excellent sputum excretion of the evidence-based nursing group was 96.30%, higher than that of the conventional nursing group (P＜0.05); the off-bed time for walking of the evidence-based nursing group was (19.06±2.25)hours, earlier than that of the conventional nursing group (P＜0.05); the antimicrobial therapy duration and the length of hospital stay of the evidence-based nursing group were respectively (2.25±0.05) days and (7.69±1.25) days, shorter than those of the conventional nursing group (both P＜0.05). After the related confounding factors were adjusted, the evidence-based nursing was a protective factor for the antimicrobial therapy duration (OR=0.774, 95%CI: 0.511 to 0.894, P=0.003). CONCLUSION The evidence-based nursing can effectively facilitate the recovery of the patients at risk of infections.
