简要总结
The RELISH study will investigate a new oral nutritional supplement (fortified porridge) for older adults in hospital who are undernourished (i.e., have malnutrition). Malnutrition is a lack of nutritional intake that can lead to poor recovery from illness, increasing hospital length of stay, and elevating healthcare costs. 22% of hospitalised older adults are estimated to have malnutrition. Oral nutritional supplementation (ONS) is key in the management of malnutrition. ONS are energy and nutrient dense products designed to increase dietary intake when diet alone is insufficient to meet daily nutritional requirements. However, for the ONS to be effective they need to be palatable (i.e., taste good), so that patients consume them (i.e., have good compliance) to reap the benefits of extra calories and protein. Normally, hospital patients are offered liquid based ONS (sip feeds). However, previous research has pinpointed that 56% of older adults on geriatric wards did not like sip feeds. Hence, exploration of compliance to different ONS formats is an important research direction to maximise malnourished older adult's nutritional intake. Therefore, the current study aimed to investigate the compliance and palatability of novel fortified porridge compared to traditional sip-feeds in malnourished older adults in hospital.
详细描述
22% of hospitalised older adults are estimated to be in a state of malnutrition. Malnutrition, also known as undernutrition, is a lack of nutritional intake leading to decreased fat free mass and diminished physiological functioning. Malnutrition impairs patient recovery, increasing hospital length of stay and escalating healthcare costs. Therefore, the identification and management of malnutrition is a vital patient-centred outcome to enhance older adult's health and quality of life and to enable cost-effective treatment and care.
A key method to support individualised nutritional care of hospital in-patients is the use of oral nutritional supplementation (ONS). ONS are energy and nutrient dense products designed to increase dietary intake when diet alone is insufficient to meet daily nutritional requirements. Overall, research suggests favourable impacts of ONS on nutritional status and healthcare costs, while the impact on functional outcomes and mortality are more controversial. A burgeoning evidence base attests to the importance of considering acceptability and compliance of ONS on adequate intake and thus effectiveness of ONS in practice.
Patient compliance to ONS considers the relationship between the amount of ONS prescribed and the amount of ONS ingested and is important to maximise clinical and cost-effectiveness. Palatability refers to the hedonic (i.e., pleasantness) evaluation of sensory factors, such as taste and smell, leading to alterations in food or fluid consumption. Supplemental preference may be affected by a multitude of factors such as taste, colour, smell, after taste and texture. Typically, hospital patients are offered liquid based ONS (sip feeds). However, previous research has pinpointed that 56% of older adults on geriatric wards did not like sip feeds. Hence, exploration of compliance to different ONS formats is an important research direction to maximise malnourished older adult's nutritional intake.
Malnourished hospitalised older adults should be offered an improved range and provision of ONS to suit patient preferences and maximise intake. For instance, an attractive alternative strategy is the use of energy and protein-dense meals (via fortification) or snacks (supplementation), including fortified bread, protein-enriched main meals and between meal snacks, such as biscuits, yoghurt and ice cream. Yet this is an understudied area, with limited data investigating compliance to alternative ONS products compared to ready-made drinks in hospital, such as powdered ONS and snacks, or their clinical effectiveness. Therefore, the current study aimed to investigate the compliance and palatability of novel fortified porridge compared to traditional sip-feeds in malnourished hospitalised older adults.

结局指标
主要结局
Percentage of the Mean Oral Nutritional Supplement Consumed Per Day (%)
时间窗: Measured daily during the 4 day testing period
Compliance to oral nutritional supplementation. Leftovers will be weighed (g) using weighing scales (Seca Model 875 digital weighing scale).
Energy (kcal) Consumed
时间窗: Measured daily during the 4 day testing period
The average amount of daily energy consumed for each nutritional supplement (kcal)
Protein Intake (g)
时间窗: Measured daily during the 4 day testing period
The average daily amount of protein consumed from nutritional supplements (g)
Palatability of Oral Nutritional Supplement
时间窗: Measured at baseline
Palatability ratings, including appearance, smell, taste, sweetness, texture, thickness, aftertaste, mouth feel, and overall likability were assessed with a 7-point hedonic Likert scale (7 = definitely like, 6 = moderately like, 5 = mildly like, 4 = neither like nor dislike, 3 = mildly dislike, 2 = moderately dislike, 1 = definitely dislike).
次要结局
- Total Caloric Intake (kcal)(Completed daily during the 4 day testing period and 2 days before testing (baseline).)
