Perspectives of registered dietitians and factors associated with their personal accomplishment in the management of cancer cachexia

Purpose Registered dietitians (RDs) have the potential in cancer cachexia management. We investigated RDs’ knowledge on cancer cachexia and assessed the effects of factors on RDs’ perception of playing an important role in cancer cachexia management. Methods This is a secondary analysis of a survey examining the perspectives of health care professionals on cancer cachexia management. We sent the questionnaire to 451 RDs. RDs were divided into two groups: RDs with and without the perception. Comparisons were made using the Mann–Whitney U test or chi-square test. To examine the effects of factors on the perception, estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the logistic regression model were calculated. Results A total of 237 RDs were analyzed. Significant differences were observed in the number of cancer patients/month, the primary area of practice, the number of clinical guidelines used, the number of items used, the number of symptoms used, and training for cancer cachexia management ( p values all < 0.05). After adjustments, the factors of cancer care experience ≥ 20 years (OR 8.32, 95% CI 1.22–56.70; p = 0.030), the number of patients/month ≥ 50 (OR 27.35, 95% CI 3.99–187.24; p = 0.001), using the clinical guidelines (OR 2.69, 95% CI 1.29–5.61; p = 0.008), the number of items ≥ 5 (OR 3.52, 95% CI 1.47–8.40; p = 0.005), and receiving training (OR 3.91, 95% CI 1.77–8.67; p = 0.001) significantly associated with the perception. Conclusion Specific knowledge and training as well as abundant experience were associated with the perception.
