Comprehensive Geriatric Assessment and Nutrition-Related Assessment: A Cross-Sectional Survey for Health Professionals

(1) Background: It is important to assess physical and nutritional status using the Comprehensive Geriatric Assessment (CGA). However, the correlation between the CGA usage and nutritional-related assessments remain unclear. This study aims to clarify the correlation between the CGA usage and other nutritional-related assessments. (2) Methods: We conducted a questionnaire survey on clinical use of CGA, assessment of sarcopenia/sarcopenic dysphagia/cachexia, and defining nutritional goals/the Nutrition Care Process/the International Classification of Functioning, Disability, and Health (ICF)/the Kuchi–Kara Taberu Index. (3) Results: The number of respondents was 652 (response rate, 12.0%), including 77 who used the CGA in the general practice. The univariate analyses revealed that participants using the CGA tended to assess sarcopenia (P = 0.029), sarcopenic dysphagia (P = 0.001), and define nutritional goals (P < 0.001). Multivariate logistic regression analyses for the CGA usage revealed that using ICF (P < 0.001), assessing sarcopenia (P = 0.001), sarcopenic dysphagia (P = 0.022), and cachexia (P = 0.039), and defining nutritional goals (P = 0.001) were statistically significant after adjusting for confounders. (4) Conclusions: There are correlations between the use of CGA and evaluation of sarcopenia, sarcopenic dysphagia, and cachexia and nutritional goals.
