  "abstract": "Background: To evaluate the association of a structured out-of-hospital continuity of care intervention with diabetic ulcer healing and patient-reported outcomes in individuals with severe diabetic foot ulcers (DFUs), and to identify prognostic factors influencing healing.\n\nMethods: This retrospective comparative study included 91 inpatients with severe DFUs (Wagner grades 4–5). The intervention group (n = 45) received a structured out-of-hospital care protocol comprising domiciliary visits, remote monitoring, and access to specialized care as needed. The control group (n = 46) was provided with standard post-discharge follow-up. Outcomes included ulcer healing status, time to complete wound closure, and health-related quality of life (HRQoL). Factors related to wound healing were assessed using Fine-Gray competing risks regression, with major amputation and death treated as competing events.\n\nResults: Over a mean follow-up of 10.74 ± 9.05 months, the intervention group showed a higher ulcer healing rate compared to the control group (82.22% vs. 63.04%; difference 19.20%, 95% CI: 0.80% − 37.50%, p = 0.060). In the Fine-Gray competing risks analysis, the intervention group was associated with a significantly higher probability of healing (subdistribution hazard ratio = 1.74, 95% CI: 1.08–2.83, p = 0.024). Regarding HRQoL, a transient between-group difference in EQ-5D-5L was observed at 6 months (p = 0.029), but the group-by-time interaction was not significant (p = 0.220), indicating no sustained improvement.\n\nConclusion: In this exploratory retrospective study, structured out-of-hospital continuity of care was associated with a statistically non-significant increase in crude healing rates. After accounting for competing risks, a significant association was observed in the primary analysis. However, this effect was attenuated and no longer significant in additional baseline severity factors (ABI and ulcer location). A transient improvement in quality of life at 6 months was not sustained. Ulcer severity and peripheral artery disease were identified as independent prognostic factors. Larger prospective studies are needed to confirm these exploratory findings.\n\nSupplementary Information: The online version contains supplementary material available at https://doi.org/10.1186/s12902-026-02431-7.",
