Compliance to Oral Nutritional Supplements (ONS) in Undernourished Frail Older Adults Living at Home.

Compliance to Oral Nutritional Supplements (ONS) in Undernourished Frail Older Adults Living at Home.

In this study, patients are supposed to take Fortimel® Protein, an Oral Nutritional Supplement (ONS) recommended in case of malnutrition once daily during the study period. Three visits will be planned for each patient enrolled in the study (baseline visit, visits of follow-up at 4 weeks and 12 weeks). Phone calls will be regularly organized during one month or three months according to the duration of supplementation. The primary purpose of the OFraDDom study is to assess the compliance with ONS (respect by the patient of the physician's prescription) at the end of the first month. Data regarding the beneficial effects of ONS, or compliance with ONS in frail elderly population, are very limited. The study could complete knowledge about oral nutritional supplementation in the undernourished frail elderly people and help to demonstrate that oral nutritional supplements have benefits on nutritional status and physical performances in frail elderly people.

For elderly with Protein Energy Malnutrition (PEM) or at nutritional risk, evidences support that Oral Nutritional Supplements (ONS) and dietary counselling can increase dietary intake and improve quality of life. However, data regarding the beneficial effects of ONS, or compliance with ONS in frail elderly population, are very limited. In their RCT, testing the effect of protein supplementation, Tieland and colleagues (7) showed an improvement of SPPB in frail older adults randomized to receive 15 g of supplemental protein daily for 24 weeks compared with the placebo group (p=0.02). Another recent RCT on the effect of a daily supplementation with protein and micronutrients for 12 weeks in 87 frail older adults (usual gait speed <0.6 m/s; MNA < 24) showed that Physical Functioning increased by 5.9% (1 point) in the intervention group, although no change was observed in the control group. SPPB remained stable in the intervention group, although it decreased by 12.5% (1 point) in controls (8). In this study, patients are supposed to take Fortimel® Protein, an ONS recommended in case of malnutrition once daily during the study period. Patients fulfilling eligibility criteria will be asked whether they are interested to participate in the study and receive Fortimel® protein. After informed consent, three visits will be planned for each patient enrolled in the study (baseline visit, visits of follow-up at 4 weeks and 12 weeks). Phone calls will be regularly organized during one month or three month according to the duration of supplementation to collect the compliance with ONS and coach patients. First prescription of the study product will be done for one month. Prescription will be repeated for 2 additional months only after the patient's nutritional status and its global health status, as well as tolerability and compliance to the ONS, were re-assessed during the first follow-up visit at one month. Data regarding the beneficial effects of ONS, or compliance with ONS in frail elderly population, are very limited. To complete knowledge about oral nutritional supplementation in the undernourished frail elderly people, study purpose is to assess Fortimel® Protein compliance to know if this supplementation is well accepted and what are factors which limit compliance. More, it could help to demonstrate that oral nutritional supplements have benefits on nutritional status and physical performances in frail elderly people.
