Diabetes mellitus is a chronic disease with an increasing prevalence and a high risk of complications such as diabetic ulcers, which can lead to amputation. Effective wound care is essential to accelerate the healing process. Modern hydrocolloid dressing has become a widely used method because it creates a moist wound environment that supports healing. Methods: This study employed a literature review method using the PRISMA approach. Articles were searched through the Google Scholar database using keywords related to modern hydrocolloid dressing and diabetic wound healing. From an initial 137 articles, a selection process was conducted, resulting in 10 articles that met the inclusion criteria (published between 2021–2026, full-text availability, and relevance to the research variables) for analysis. Results: The review results indicate that modern hydrocolloid dressing is consistently more effective than conventional methods in accelerating diabetic ulcer wound healing. This effectiveness is demonstrated by a reduction in wound scores, increased granulation and epithelialization, decreased necrotic tissue, and reduced risk of infection and pain. The principle of moist wound healing plays a significant role in enhancing tissue regeneration. Conclusion: Modern hydrocolloid dressing is proven to be effective in accelerating wound healing in patients with diabetes mellitus compared to conventional care. Therefore, this method is recommended as an intervention in nursing practice to improve wound care quality and patient clinical outcomes.
