Nutrition support in hospitalised adults at nutritional risk
There is low‐quality evidence for the effects of nutrition support on mortality and serious adverse events. There is very low‐quality evidence for an increase in weight with nutrition support at the end of treatment in hospitalised adults determined to be at nutritional risk. The effects of nutrition support on all remaining outcomes are unclear.
There is no consensus whether poor nutritional status causes poorer clinical outcomes or whether it is merely associated with poor outcomes. The intention with all forms of nutrition support is to increase uptake of essential nutrients and improve clinical outcome. This review aims to assess the benefits and harms of nutrition support versus no intervention, treatment as usual, or placebo in hospitalized adults at nutritional risk.
