Aims: Critical colonization in pressure ulcers delays healing and has been studied. However, local wound management includes no clear strategy for preventing the development of biofilms. Therefore, this multicenter, prospective, observational study was conducted to examine the effect of local management on the biofilm area of pressure ulcers with critical colonization. Methods: Participants were 34 patients with a pressure ulcer deeper than the dermis and in a state of critical colonization. The primary outcome was the change over a week in the proportion of the biofilm area in relation to that of the pressure ulcer area. We investigated the relationship between primary outcome and local wound management. The wound-blotting method was used for determining the biofilm area. To calculate the change in the biofilm area, baseline proportion was subtracted from proportion 1 week later. Results: Six types of topical treatment were used in three facilities. The proportion of the biofilm area at 1 week follow-up was significantly smaller with iodine ointment than that without iodine ointment (p =.02). The standardized partial regression coefficient of iodine ointment adjusted by the type of medical facility was −0.26 (p =.003). Conclusion: This study revealed that the use of iodine ointment reduced the proportion of the biofilm area in the pressure ulcer surface. To manage pressure ulcers in a state of critical colonization, these results suggest that local management include the use of iodine ointment.
