Abstract
En 中文
Background: Chronic wounds pose a persistent therapeutic challenge. Type I collagen and hyaluronic acid (HA) support tissue repair, but real-world evidence for describing their combined use in padformulations is limited. This study provides a real-world description of clinical outcomes observed within a tailored management, including Type I Collagen–Hyaluronic Acid pads (HCHA), on healing trajectories across diverse chronic wound etiologies. Methods: This retrospective observational analysis included 64 patients treated between 2017 and 2024 for chronic wounds, including burns (n = 32) and trophic ulcers of various etiologies (n = 32). Clinical data, including wound characteristics, daily healing rate (DHR), and procedural pain assessed using repeated VAS measurements, were extracted from medical records. Results: The daily healing rate (DHR) ranged from 3.22% in neglected burn wounds to 2.03% in non-burn chronic wounds. Percent area reduction (PAR) analysis at 7, 14, and 30 days showed greater wound area reduction in burn wounds (20%, 36%, and 62%) compared with non-burn wounds (13%, 25%, and 45%). Procedural pain decreased in both cohorts, with burn injuries presenting higher baseline VAS scores but following a similar downward trajectory over time (p < 0.001), converging to comparably low levels by day 30. Overall, the findings describe the outcomes observed within an individualized, multimodal wound care approach, which incorporates HCHA pads tailored to wound-specific characteristics. Conclusions: In this retrospective observational study, patients treated with HCHA pads as part of individualized multimodal wound care exhibited progressive granulation, favorable wound-healing trajectories, and lower procedural pain levels. Further controlled studies are warranted to validate these results and refine the patient selection criteria.
