Abstract
|
|
|
Purpose: The purpose of this study was to explore whether or not there is a relationship between doctor's awareness of clinical nutrition service and needs for a clinical dietitian.
Methods: A cross-sectional survey design was used. The research was carried out by using questionnaires that had been specifically designed for the study. The research was conducted from September to October, 2013 for 311 doctors at 43 hospitals (with over 400 beds). Frequency analysis, factor analysis, reliability analysis, confirmatory factor analysis, and bootstrapping analysis were conducted using SPSS 21.0.
Results: 'Implementation of clinical nutritional service' (p < 0.001) and 'usefulness on clinical nutrition service' (p < 0.001) were found to be correlated with 'importance of clinical nutrition service' as an independent variable. The correlation between 'importance of clinical nutrition service' as a mediating variable and 'needs for clinical dietitian' as a dependent variable was also confirmed (p < 0.001). The results of the bootstrapping test showed that the mediating effect of 'importance of clinical nutrition service' was significant. The indirect effect value between 'implementation of clinical nutrition service' and 'needs for clinical dietitian' was 0.040, indirect effect value between 'usefulness on clinical nutrition service' and 'needs for clinical dietitian' was 0.095.
Conclusion: The frequency of providing clinical nutritional services, the quality of clinical nutritional services, and the degree of implementation of clinical nutritional services were found to be important for positive perception of clinical nutrition services by doctors. Therefore, proper provision of clinical nutrition services and effective therapeutic effects will be continuously highlighted, which will increase the awareness of the physician and ultimately increase the demand for clinical nutrition service.
