Poor Interrater Reliability of Retrospectively Applied Subjective Global Assessment for Malnutrition in the Critically Ill

摘要

The Subjective Global Assessment (SGA) has been recommended to assess nutritional status, yet its performance in the intensive care unit (ICU) has not been vigorously validated. We sought to determine whether retrospectively applied SGA using the electronic health record (EHR) offered satisfactory interrater reliability. Validity and reliability of the retrospectively applied SGA were assessed in 398 ICU patients between 2008 and 2015. Interrater reliability between registered dietitian/nutritionist- and physician-determined SGA score was poor (weighted kappa = 0.35; 95% CI, 0.27-0.43). The SGA exhibited poor interrater reliability in ICU patients, and the utility was limited by the availability of data in the EHR.
