Clinical evaluation of UrgoStart Plus dressings in real-life conditions: results of a prospective multicentre study on 961 patients

Abstract

Aims: This study aimed to evaluate the performances of lipid colloid technology with nano-oligosaccharide factor (TLC-NOSF) dressings with polyabsorbent fibres in an unselected population of patients under real-life conditions. Methods: A large, prospective, multicentre, observational study with three polyabsorbent TLC-NOSF dressings (UrgoStart Plus Pad, UrgoStart Plus and UrgoStart Plus Border, Laboratoires Urgo, France) was conducted in Germany between January 2019 and June 2020. Main outcomes included wound healing rate, clinical assessment of wound healing progression, local tolerance and acceptance of dressings, and changes in health-related quality of life (HRQoL) of the patients, assessed with the validated Wound-QoL questionnaire. Results: A total of 961 patients with wounds of various aetiologies (leg ulcers (LU), diabetic foot ulcers (DFU), pressure ulcers (PU) and other types of wounds) were treated with the evaluated dressings in 105 centres for a mean duration of 62 days (standard deviation 37 days). By the last visit, a wound closure or an improvement in wound healing was reported in 92.0% of the treated wounds. The highest wound closure rates were achieved when the dressings were used as first-line treatment: 71.3% in DFUs, 52.9% in LUs, 53.6% in PUs and 61.8% in the other wounds. Improvement of the wound healing process was also associated with an 87.5% relative reduction of sloughy tissue, a decrease of the level of exudate in 68.9% of the wounds, and an improvement in the periwound skin condition in 66.4% of the patients at the final visit. The dressings were ‘very well’ or ‘well’ tolerated and ‘very well’ or ‘well’ accepted by the large majority of patients. The HRQoL questionnaires were completed both at initial and final visits by 337 patients, representative of the total cohort. Despite the relatively short duration of the wounds, the HRQoL of the patients was already impaired at baseline, with 81.6% of the patients being severely affected in at least one aspect of their HRQoL. By the final visit, significant improvements in each dimension of the patients' HRQoL were reported (p<0.001), along with a reduction of the proportion of patients in need of intervention and in the number of actions needed per patient in relation to their HRQoL. Conclusions: These results are consistent with previous clinical evidence on TLC-NOSF dressings. They confirm the good healing properties and safety profile of these dressings, and that a significant improvement in patient HRQoL is achieved in non-selected patients treated in real-life practice. These data support the use of such dressings as a first-line intervention and until wound healing in the management of chronic wounds, in association with appropriate standard of care.
