Key result
Subjective global assessment shows high interobserver agreement for evaluating nutritional status in hospitalized patients.
Why the study?
The study aimed to clarify the nature of Subjective Global Assessment (SGA) and determine which clinical variables influence clinicians' SGA ratings.
Population
202 hospitalized patients before gastrointestinal surgery

SGA offers a practical bedside tool for preoperative nutritional assessment; leaves open its reproducibility, outcome prediction, and role in guiding care.

Subjective Global Assessment is a reproducible clinical technique for assessing nutritional status that can be easily taught to clinicians.
Charles J. Foulks (2001) conducted an observational in Hospitalized patients before gastrointestinal surgery (n=202). Subjective global assessment (SGA) was evaluated on Interobserver agreement of SGA ratings (kappa 0.78, 95% CI 0.624-0.944, p=<.001). Subjective global assessment demonstrated a high degree of interobserver agreement (kappa = 0.78; 95% CI 0.624-0.944; p < 0.001) among clinicians evaluating hospitalized patients.
