van den Berg, G. et al. 2015. The effects of the administration of oral nutritional supplementation with medication rounds on the achievement of nutritional goals: a randomized controlled trial

A randomised controlled trial which had the aim of investigating whether providing a lower volume of ONS at a higher frequency during medication rounds would improve the intake of supplements.  The results showed that a higher frequency of a lower volume of ONS during medication rounds increased the compliance of patients needing ONS.
