Assessing Health Professional Students' Cultural Competence Using a Global Perspective.

BACKGROUND: The United States has become a diverse society, and healthcare professionals must view culture from a global perspective. The purpose of this study was to determine cultural competence levels of entering and exiting health science students within and across differing professional programs using the Global Worldview Cultural Competence Survey (GWCCS). PARTICIPANTS: 196 students participated in the study: 146 were entering students and 59 were exiting students. From the 146 entering students, 138 surveys were usable in the data analysis, and 58 of the 59 exiting were usable. PROCEDURE: Two separate cohorts of health professional students completed the GWCCS. Cohort 1 completed the GWCCS during the first 2 weeks of their academic program, and Cohort 2 completed the GWCCS in their final-year post-clinical experience. RESULTS: A significant difference in GWCCS total score was observed between entering and exiting students in health sciences, with the exiting students being more culturally competent. CONCLUSION: Although this study did not utilize a longitudinal study design, the findings demonstrate that the exiting cohort of health science students was more culturally competent than the entering cohort of health science students as determined by the GWCCS. However, neither cohort of students reached the level of proficiency.

Interface dressings influence the delivery of topical negative-pressure therapy.

BACKGROUND: Topical negative-pressure therapy is a widely used wound management system that generates a negative pressure at the wound surface through a foam pad, which aids in wound stimulation through mechanical forces on the wound bed. System guidelines state that the foam dressing should be placed in direct apposition with the wound surface; however, an interface dressing is often inserted at this point to promote comfort at dressing changes. METHODS: Topical negative-pressure dressings were applied to 40 healthy volunteers. Pressures at the skin surface under the dressing were recorded and compared with those measured by a topical negative-pressure machine using the Therapeutic Regulated Accurate Care pad system. These were repeated, inserting different types of interface dressings: petroleum jelly (Vaseline)-impregnated gauze, nonadherent silicone dressing, and mylar polyester film dressing. RESULTS: Pressures recorded at the skin interface with no interface dressing were close to those set on the topical negative-pressure machine (mean pressure change, -5.11 +/- 0.55 mmHg). Interposition of dressings at the skin/foam interface affected pressure transmission through the foam, and some caused significant decreases in pressures recorded at the skin surface (e.g., Vaseline-impregnated gauze: mean pressure change, -11.76 mmHg; maximum pressure change, -41 mmHg). CONCLUSION: The loss in negative pressure means that pressures designated by the machine cannot be relied on as a measure of wound pressure when certain dressings are used at the interface. This could be important in determining the outcome of some wounds under topical negative-pressure therapy treatment.
