Promoting Compliance with Fortisip Compact Protein

Energy and protein are required for muscle protein synthesis, which could help address the characteristic loss of muscle reserves in frailty.10 However many older adults may struggle to meet their daily protein requirements with food alone.11

High protein oral nutritional supplements may be useful for frail elderly patients at high risk of malnutrition, as they significantly improve energy and protein intakes (without impacting dietary intake), body weight, body composition and function, whilst reducing risk of clinical complications.12

Frail patients at risk of malnutrition are likely to have poor appetite and therefore may struggle to finish large volumes of ONS. In addition, they may have poor dexterity and muscle weakness, which may cause difficulty in preparing powdered ONS, making them less clinically effective and therefore less cost effective. For these patients, low volume, ready to drink ONS may be more suitable. High energy, low volume, ready to drink ONS (125ml) are associated with significantly better compliance (91%) compared to ‘standard’ ONS (typically 200ml or more, 78%).13,14 A wide variety of flavours is also associated with improved compliance.15
