The models of critiquing should focus on various aspects of nursing practice but more applicable for a specific case like wound care (Pearson et al., 2005). In order to improve wound healing it is necessary to improve the wound environment, as bacteria delay healing by competing with host cells (Fong & Wood, 2006). According to the ISI Journal Citation reports ranking in 2012, the Wound Repair and Regeneration Journal was ranked11/59 in dermatology, 28/199 (surgery,) 109/185, (cell biology) and 50/ 121 (Medicine Research & Experimental) (Hebda, 2014) Miler et al (2010) focus on the differences between cadexomer iodine and nanocrystalline silver on the healing of leg ulcers. Leg ulcers have a more devastating impact than most wounds, with bacterial colonization likely to lead to infection.
