Subjective Global Assessment Of Nutritional Status Research Articles

Risk for undernutrition and development of pressure injury in hospitalised patients in Brazil: Multicentre prospective cohort study.

Although pressure injury (PI) is preventable, the number of patients developing this type of injury is still high. In this prospective cohort study, we aimed to assess whether high risk for undernutrition was a risk factor for PI in 1937 patients aged ≥18 at six hospitals in Sao Paulo, Brazil. Patients' risk for undernutrition was assessed using three unique screening tools. Risk for PI was assessed using the Braden Scale. Data were analysed using Poisson regression with robust variance (95% CI, P ≤ .05). While 57.1% of patients were at risk for undernutrition in the Nutritional Risk Screening (NRS 2002), only 36.8% and 2.6% were at risk in the Braden Scale Nutrition Subscale (BSNS) and Subjective Global Assessment of Nutritional Status (SGANS), respectively. The cumulative incidence rate was 5.9%. Of those who developed PI, 91.2%, 56.2%, and 18.4% were at risk for undernutrition in the NRS 2002, BSNS, and SGANS scales, respectively. We found a significantly higher risk for PI in patients who were at risk for undernutrition compared with those who were not at risk, supporting previous evidence about the role of undernutrition as a key risk factor for PI in hospitalised patients.

Application of subjective global assessment as a screening tool for malnutrition in surgical patients in Vietnam

In most hospitals in Vietnam, clinical assessment of nutritional status has yet to become part of the routine clinical history taking and physical examination. It is the aim of this study to apply subjective global assessment (SGA) of nutritional status in surgical patients in the Mekong Delta, Vietnam, to determine the incidence of malnutrition according to SGA and to know whether there was an association between SGA class and infectious complications. A prospective, cross-sectional study design was used. SGA of nutritional status was applied. Patients were rated as well nourished (A), moderately malnourished (B) or severely malnourished (C). Infectious complications (wound infection, intra-abdominal abscesses, anastomotic leakage) were recorded. Of the 438 patients assessed, 194 (44.3%) were classified as A, 126 patients (28.8%) were classified as B and 118 patients (26.9%) were classified as C. Of the 274 patients who underwent major abdominal surgery assessed, 61 patients (22.3%) were classified as A, 97 patients (35.4%) were classified as B and 116 patients (42.3%) were classified as C. Weight loss and percent weight loss, muscle wasting, loss of subcutaneous fat, functional capacity and significant gastrointestinal symptoms correlate significantly with the severity of SGA class (P<0.001). The rate of postoperative infectious complications was higher in patients classified as SGA class C (33.6%) than as class A (6%) and B (11%). A high rate of malnutrition was found, applying SGA of nutritional state in surgical patients in Vietnam. Malnutrition was associated with an increase in infectious complications. Special attention should be paid to weight loss, muscle wasting, loss of subcutaneous fat, functional capacity and gastrointestinal symptoms.

The Swedish version of the patient-generated subjectiveglobal assessment of nutritional status: gastrointestinal vs urological cancers

Purpose: To translate and evaluate the Patient - Generated Subjective Global Assessment (PG-SGA) a method for the assessment of nutritional status. Method: Eighty-seven patients with gastrointestinal and urological tumours completed four sections and the remaining sections were independently completed by a doctor and a dietician. Patients were classified as SGA A (well nourished), SGA B (moderately/suspected of being malnourished) or SGA C (severely malnourished). Results: Interobserver agreement was complete in 90% of the cases. More patients with gastrointestinalcancers than with urological cancers were classified as SGA B and C. Mean levels of S-albumin and P-prealbumin differed between the SGA-classes. Multivariate logistic regression analyses showed independent contributions to the overall classification by weight loss in the last 6 months, level of food intake, problems with eating, physical activity and muscle wastage. Survival was significantly higher in SGA A than in SGA B+C, P< 0.001. Conclusion: The PG-SGA is useful for the assessment of nutritional status. Patients had no problems in answering the questions. The PG-SGA also carried prognostic information.
