Although the benefits of healing in a moist environment have been published worldwide, the use of woven gauze as a wound contact material still prevails in many countries. This article traces the history of gauze and problems associated with usage against the introduction of one of the first modern materials, the hydrocolloid. Why this revolution in dressing material did not herald an immediate change of practice away from gauze is examined. Since the 1970s, the range, availability and sophistication of these and other moisture-retentive dressings have increased dramatically, and yet it seems that some practitioners remain unconvinced. The processes that underpin personal and organisational change that may contribute to this reluctance are also considered.
