Influence of a changed care environment on bacterial colonization of burn wounds.

This study investigated the influence of a conditioned care environment per se on bacterial colonization of burn wounds. Two cohorts of burn patients were treated in the successive years 1992 and 1993, the first group in a (permanent) purpose-designed unit and the second in wards of traditional 'open' design, during renovation of the unit. Patients who were admitted to the permanent and temporary units numbered 224 and 231 respectively, the groups being similar in features that generally influence the course and outcome of burn injuries. The principles and practice of treatment by the burn care team remained the same in both years. No significant difference in wound colonization rates was found between the two groups. We conclude that while the other known advantages of managing burn patients in purpose-designed units remain valid, a conditioned care environment per se does not influence bacterial colonization rates of burn wounds.
