Q4. How should nutritional status be assessed?

Summary

The Evidence Based Practice Guidelines for Nutritional Management of Malnutrition in Adult Patients Across the Continuum of Care state that validated tools for your patient population should be used for assessment [1]. The scored Patient-Generated Subjective Global Assessment (PG-SGA) [2] and Subjective Global Assessment (SGA) [3] have been validated for use in the cancer population and are recommended in the Evidence Based Practice Guidelines for Nutritional Management of Patients Receiving Radiation Therapy [4] and the Evidence Based Practice Guidelines for the Nutritional Management of Cancer Cachexia [5].

Three studies examined the use of PG-SGA in the head and neck cancer population. Isenring et al. [6] (level II, positive quality) found a statistically smaller deterioration in nutritional status (determined using the PG-SGA) of head and neck or gastrointestinal cancer patients receiving nutritional intervention compared with usual care. Kiss et al. [7] (level III-3, neutral quality) utilised the PG-SGA as the key component of the nutrition care pathway used to direct care in a dietitian-led clinic for head and neck cancer patients receiving (chemo)radiotherapy, with the positive outcomes of this intervention outlined further in question 5. Britton et al. [8] (level II, positive quality) used the PG-SGA to determine the presence of malnutrition and predictors thereof in head and neck cancer patients undergoing radiotherapy.

A level III-2 neutral quality study reported that serum leptin levels could be used to determine level of cachexia in patients with oral SCC, as leptin levels correlated with body fat mass, and were found to be lower in patients with oral SCC [9].

One level III-3, neutral quality study [10] validates hand grip strength as an indicator of nutritional status, however, these single parameter measurements do not provide an adequate overall assessment of nutritional status [11].

Recommendation Grade
Use a validated nutrition assessment tool (e.g. scored Patient Generated–Subjective Global Assessment or Subjective Global Assessment) to assess nutritional status.
