Topics in Clinical Nutrition: April/June 2020 - Volume 35 - Issue 2 - p 93-103 doi: 10.1097/TIN.0000000000000191 Buy Metrics Abstract In this repeated-measures pre/postintervention study, we evaluated the effect of high-fidelity patient simulation-based learning (HPSL) on dietetics students' self-efficacy in applying the nutrition care process. Furthermore, we assessed their perceptions, attitudes, satisfaction, and self-confidence toward HPSL. Forty-one Saudi dietetics undergraduates participated in an HPSL exercise involving a newly diagnosed diabetic ketoacidosis case. We found that the students' self-efficacy score in applying the nutrition care process significantly increased (P = .01) following the intervention, from 3.0 (interquartile range [IQR] = 2.4-3.2) to 3.2 (IQR = 2.8-3.5), and participants reported overall positive attitudes toward HPSL, including enhanced perceived benefits to communication skills. © 2019 Wolters Kluwer Health, Inc.
