SUBJECTIVE GLOBAL ASSESSMENT IS NOT A RELIABLE INDEX IN ASSESSING THE NUTRITIONAL STATUS OF PATIENTS ON HAEMODIALYSIS

Subjective global assessment (SAG) is accepted as a reliable method in assessing the nutritional status of a patient on haemodialysis. A total of 34 patients participated in the study (18 male, 16 female, mean age (yrs) = 58,7 ± 15,3, mean duration on haemodialysis treatment (yrs) = 3,98 ± 3,54). Compared to those of fourteen patients with mild malnutrition (SGA-B), the antrophometric measurements of well-nourished patients (SGA-A, n:20) were found better. The serum levels of intact parathyroid hormone and phosphorus of patients in SGA-A group were significantly higher, compared to those of SGA-B group. But, there were not any statistically significant differences between the levels of several biochemical parameters (serum albumin, cholesterol, transferin, ferritine), when compared two groups. SGA data did not correlate well with biochemical parameters. We concluded that SGA results were not concordant with biochemical nutrition parameters and SGA was not capable in assessing the nutritional status of patient on haemodialysis treatment.
