Effects of PechaKucha presentation about prevention of pressure injury on knowledge of elderly care department students: a randomized controlled study

Abstract

Background: PechaKucha (PK) is a presentation technique that uses visual and narrative presentations consisting of 20 slides, each shown for 20 seconds. Purpose: The aim of this study was to evaluate the effects of the PK presentation on elderly care department students’ knowledge about pressure injury prevention. Methods: This study used a single-blinded randomized control trial. Elderly care department students were randomized to the PK presentation technique (intervention group) and traditional PowerPoint presentations only (control group). The sample of the study consisted of 54 (intervention group = 28, control group = 26) elderly care department students. Data was collected using the Sociodemographic Form and the Pressure Ulcer Prevention Knowledge Assessment Instrument (PUPKAI). PUPKAI was administered before the presentations (pre-test), after the presentations (post-test 1), and 4 weeks after the presentations (post-test 2). Results: Following the presentations, the intervention group's PUPKAI mean score (47.23 ± 11.62) was significantly higher than the control group's mean score (36.64 ± 12.41) (P < .05). Four weeks after completing the education, the intervention group's mean PUPKAI score (43.11 ± 13.72) was significantly higher than the control group's mean score (36.46 ± 12.76) (P < .05). Conclusion: The knowledge level of the elderly care department students was found to be below the satisfactory level. It was determined that the PK presentation increased the knowledge level of the students regarding pressure injury prevention.
