At the site of wound repair, TEWL measures functional wound closure as marked by re-establishment of barrier function at the wound site. This review article addresses recent developments in clinical TEWL measurement in the context of human skin health and wound care. To that end, emphasis is placed on the review of registered clinical studies reported in ClinicalTrials.gov for which TEWL results have been posted or published. <b>Recent Advances:</b> The U.S. Food and Drug Administration (FDA) defines complete wound closure as the achievement of 100% re-epithelialization of the wound surface, with no detectable exudate, drainage, or need for wound dressing, as verified during two sequential clinical assessments conducted at least 14 days apart. Clinically, wounds may meet this current FDA-recommended clinical criteria for wound closure, yet not achieve functional wound closure which requires the re-establishment of barrier function at the site of repair. Such wounds are likely to recur. High TEWL posthealing predicts wound recurrence. Thus, TEWL measurement at the site of repair posthealing is emerging as a significant measurement of wound healing endpoint. <b>Critical Issues:</b> Appropriate clinical measurement of TEWL requires a basic understanding of the related technologies and their appropriate use. Such understanding will help achieve the necessary rigor and reproducibility in clinical measurement. <b>Future Directions:</b> Recent reports on the critical significance of TEWL in wound care open new horizons wherein TEWL is likely to have broader applications involving altered skin barrier functions, such as during aging and other factors that determine skin health. Evidence to support revisiting the FDA definition of wound closure to include restoration of barrier function at the site of closure is strong. Widespread adoption of TEWL in wound care practices to determine functional wound closure is anticipated.</p>","PeriodicalId":7413,"journal":{"name":"Advances in wound care","volume":" ","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is unknown whether higher rates of successful wound healing are associated with better long-term outcomes. We sought to determine the association of risk-adjusted healing rates in wound care clinics with postdischarge outcomes. <b>Approach:</b> This observational study compared outcomes of Medicare patients with chronic wounds who received care at clinics with the highest risk-adjusted wound healing rates (<i>n</i> = 91) to those with the lowest rates (<i>n</i> = 88) in a network of 510 specialized U.S. wound care clinics.

This finding can inform analyses to understand differences in practice patterns that lead to better outcomes. <b>Conclusion:</b> Treatment of chronic wounds in wound care clinics with higher risk-adjusted healing rates is associated with a lower risk of wound-related adverse events during follow-up, particularly in the first year.
