Abstract:

Introduction: The skin performs important structural and physiological functions, and skin assessment represents an important step in the diagnosis and prognosis of pathology. Although many non-invasive techniques for assessing skin status exist, a novel assessment tool, involving ‘blotting’ the skin or a wound’s surface chemistry, has seen increasing experimental use. Burn injuries represent extreme forms of skin injury, and pathological scars have undesirable consequences. This review explores the utility of blotting in the diagnosis and prediction of skin pathophysiology, and how this translates as a tool for burns.

Methods: Following the submission of the protocol to the OSF.io database, the systematic review was conducted adhering to the PRISMA 2020 guidelines.

Results/Discussions: Through a comprehensive search of the last 15 years, 40 papers were identified and illustrated preliminary insights into:
(A) Blotting as a non-invasive tool: variations in the technique; reliability and accuracy of the results; and biomarkers that blotting is sensitive to.
(B) Blotting and its translational relevance: assessment of skin physiology; the various skin diseases blotting has been utilised for; and the relationship between blotting biomarkers with diagnosis/prognosis of skin diseases.

Conclusion: Our review summarises the literature to date on blotting. It demonstrates that non-invasive blotting of the skin surface chemistry is a technique with the potential to translate into clinical practice. It raises opportunities to expand utilisation to burns and other skin diseases; be used as an adjunct to clinical assessment; and has a role as an objective diagnostic and/or prognostic bedside tool.
