This study investigated the current readiness for hospital discharge (RHD) among patients with lower extremity peripheral arterial disease (PAD) following endovascular revascularization within an enhanced recovery after surgery (ERAS) model and analyzed its associated factors. This cross-sectional study was conducted at a large tertiary hospital in China. A total of 200 lower extremity PAD patients was conducted between December 2024 and August 2025. Data were collected using a general information questionnaire, the RHD Scale, and the Quality of Discharge Teaching Scale. The total score for RHD was 92.31 ± 16.10, and the total score for discharge teaching quality was 166.16 ± 18.72. The RHD score was positively correlated with the discharge teaching quality score (r = 0.400, p < 0.001). Marital status, education level, residence, number of comorbidities, length of stay, Fontaine's stage, and discharge teaching quality were identified as factors significantly correlated with RHD. The findings indicate that overall RHD in lower extremity PAD patients undergoing endovascular revascularization treatment is moderate, suggesting that the quality of discharge guidance requires further enhancement. Medical professionals should assess the quality of discharge teaching and RHD levels in order to take targeted intervention measures. Establishing a transitional care team and implementing long-term care management is crucial for reducing the rate of unplanned readmission.
