Response to White and Cutting critique In their letter, published in the March issue of JWC, White and Cutting raised concerns about clinical visualisation of wound biofilm in the absence of a definitive assay or validation of visual observations with microscopic confirmation. While I acknowledge that science plays a critical role in extending our knowledge of the role of biofilm in wound healing, clinicians cannot ignore patients' needs, or the patterns we observe as experts in our practice, while we await such scientific developments.
