Multicenter Study of the Validity and Reliability of Subjective Global Assessment in the Hemodialysis Population

Avaliação de métodos para identificar desnutrição energético-protéica de pacientes em hemodiálise

“…20 In our study, SGA applied to HD patients showed a predictive power for the occurrence of hospitalizations. 6 The major limitations of SGA comprise low sensitivity to assess small changes and interindividual variation when SGA is performed by a team. It is worth mentioning that the SGA model applied in the present study has been recently validated for that population, and, as it includes the possibility of classifying the nutritional status into levels, it attenuates the low sensitivity for small changes in the nutritional status.…”

“…16 Regarding SGA, a model adapted and validated to HD patients was used. 6 In that model, the nutritional status was graded with a score ranging from 1 to 7, and values closer to 7 indicated well-nourished patients. According to that score, patients were classified as follows: score 7 and 6, well-nourished; 5 to 3, mild to moderately malnourished; 2 and 1 severely malnourished.…”

“…According to that score, patients were classified as follows: score 7 and 6, well-nourished; 5 to 3, mild to moderately malnourished; 2 and 1 severely malnourished. 6 In this study, patients with SGA ≤ 5 were considered as having PEW. 6 Data from the laboratory tests were collected from the medical records and comprised the following: albumin (g/dL); creatinine (mg/dL); cholesterol (mg/ dL); and pre-and postdialysis urea (mg/dL).…”

“…6 In this study, patients with SGA ≤ 5 were considered as having PEW. 6 Data from the laboratory tests were collected from the medical records and comprised the following: albumin (g/dL); creatinine (mg/dL); cholesterol (mg/ dL); and pre-and postdialysis urea (mg/dL). The samples for the laboratory tests were always collected before the HD sessions, except for urea, whose samples were collected before and after the HD sessions.…”

“…5 Subjective global assessment (SGA) has been recently emphasized as a simple, inexpensive and validated method for assessing the nutritional status of that population. 6 In addition to SGA, the following are routinely assessed: nutrient intake, mainly by use of the three-day food recording or by use of 24-hour food recall; muscle and fat mass reserve by use of anthropometry or bioelectrical impedance; and biochemical Assessment of methods to identify protein-energy wasting in patients on hemodialysis markers by use of plasma albumin. [7][8][9] Renowned researchers in the area believe that it is necessary to jointly apply several parameters to properly assess the nutritional status of that population, to overcome the limitations of each of such methods when used in isolation.…”
