Implementation of a peer review program using the validated DIET-COMMS tool to assess dietitians' communication skills in the workplace

Aims: Communication is the main method used by dietitians to conduct their practice. Yet, few evidence-based tools are available to assess dietitians' communication skills to guide skill development. Further, workplace peer review programs for assessment of communication skills are not standard practice. DIET-COMMS is a validated tool to assess dietitians' communication skills in patient consultations. The aims of this study were to implement a workplace peer review program using the DIET-COMMS tool, assess dietitians' communication skills, evaluate inter-rater reliability and dietitian satisfaction. Methods: Single site study within Australian hospital dietetics department. Training for DIET-COMMS usage was undertaken with assessors (senior dietitians) and dietitians being assessed using an online training package and face-to-face group sessions. The peer review process consisted of two rounds, occurring four to six months apart. The first round was undertaken with two assessors to evaluate inter-rater reliability. An online survey was conducted to evaluate dietitian satisfaction. Results: Seventeen dietitians completed the program. In the first round, 13 of 17 dietitians scored 76% to 100% on the DIET-COMMS tool (median = 85%, interquartile range [IQR] = 77-93). All dietitians scored 76-100% (median = 98%, IQR = 94-100) in the second round, with significantly higher scores compared to the first (98% vs 85%; P-value <.001). The intra-class correlation coefficient was 0.86 (95% confidence interval = 0.64-0.95), indicating good-excellent inter-rater reliability. All dietitians reported the tool measured the nutrition care process adequately and was applicable to practice. Conclusions: The peer review program using DIET-COMMS was successfully implemented within a workplace environment. Widespread implementation of peer review programs using DIET-COMMS is recommended as a standard practice for the profession.
