Background & aims: The high prevalence of malnourished cancer patients highlights the importance of sensitive and specific tools for nutritional risk and status assessment screening, namely the Patient-Generated Subjective Global Assessment (PG-SGAĀ®). This study aimed to assess whether the short-form version of the PG-SGAĀ® (PG-SGAĀ© SF) would be appropriate to identify the nutritional risk of patients when compared with the final global score of PG-SGAĀ© (long-form version).
Methods: This transversal and observational study comprised a convenience sample of cancer patients undergoing chemotherapy at the Champalimaud Clinical Centre between December 2016 and February 2018. Clinical data and anthropometric parameters were collected in order to apply PG-SGAĀ® and PG-SGAĀ© SF. The data was statistically analysed through SPSS version 22 (SPSS Inc, Chicago, IL, USA).
Results: In this study 355 patients were enrolled and PG-SGAĀ© SF results showed that 69.3% (n = 246) of the population presented at least one risk factor for malnourishment (Ī£ (box A) ā„1). Additionally, PG-SGAĀ® revealed that 50% of patients (n = 177) have a risk of developing malnourishment or are already malnourished (B and C classification). The concordance of results showed to be high (coefficient k = 0.62; p < 0.001), meaning that PG-SGA SFĀ© has a good sensibility (95%) and specificity (67%) for the identification of nutritional risk and assessment of nutritional status when compared with the complete version of PG-SGAĀ©.
Conclusions: According to our results, PG-SGAĀ© SF is a useful and sufficient tool, representing an easier and faster way to identify at-risk or malnourished patients.
