Chronic wounds, including Diabetic Foot Ulcers (DFUs), Venous Leg Ulcers (VLUs) and Pressure Ulcers (PUs), present significant challenges for the patients, clinicians and healthcare systems. There remains a strong need for novel and effective technologies to accelerate the healing of these wounds. The objective of this prospective, single-arm pilot study was to evaluate the clinical performance of a novel nanofiber wound matrix for the treatment of chronic lower extremity wounds refractory to standard-of-care treatment at a single centre. A total of 15 patients with 15 chronic wounds (5 DFUs, 8 VLUs and 2 PUs) were included in this study. These wounds were non-healing to previous standard-of-care treatments for an average of 4 weeks. They were all treated with the novel nanofiber wound matrix with weekly clinical evaluation and re-application for a total duration of four (4) weeks, per the study protocol. The average wound area reduction (WAR) was 83.6% upon 4 weeks of treatment with the application of the subject wound matrix, as an adjunctive measure to the standard of care. Additionally, seven (7) of the 15 wounds (46.7%) completely healed starting from Week 3, and the average complete healing time was 13.9 days. These results demonstrated accelerated healing effects of the subject wound matrix, when compared to the standard of care reported in literature, where the average WAR was at 62.9% at Week 12, six (6) of the 18 wounds (33.3%) were completely healed within 12 weeks, and the average complete healing time was 49.0 days. These results demonstrated that the subject wound matrix is a safe and effective novel technology in treating chronic wounds, providing significant clinical and economic benefits for patients with various chronic wounds.
To synthesise evidence on nurses' roles in long-term care settings and map their interactions.
Systematic review with network analysis.
Thematic synthesis was used to identify nurses' roles, and network analysis mapped their interactions across domains.
Six databases—Cumulative Index to Nursing and Allied Health Literature, PubMed, Embase, Cochrane Library, Research Information Sharing Service and Database of Periodical Information Academic—were searched for peer-reviewed articles from 2014 to 2024. The Mixed Methods Appraisal Tool assessed study quality.
Fifteen studies were included. Nurses' roles spanned six domains: collaboration, education, leadership, resident-centred care, quality improvement and resource management. Network analysis revealed collaboration and leadership as the most central, each with a degree centrality of five, acting as bridges across domains. Three thematic clusters emerged: collaboration and resource management focused on operational teamwork; leadership and quality improvement centred on systemic care enhancements; and education and resident-centered care emphasised training and resident-focused care. A technological competence gap was identified, alongside barriers like staffing shortages and role ambiguity.
Nurses' interconnected roles are critical for resident-centered care; however, they require systemic support to address barriers and technological gaps.
Enhanced interprofessional training, leadership development and digital skill integration can improve care quality and nurse well-being in long-term care settings.
This study addressed the complexity of nurses' roles in long-term care and their structural interactions, finding collaboration and leadership as pivotal with three role clusters and a technological gap, impacting long-term care nurses, educators and policymakers to inform workforce strategies.
This study adhered to the PRISMA 2020 guidelines and was preregistered in PROSPERO (CRD42024588422).
This study did not include patient or public involvement in its design, conduct or reporting.
