nutritional therapy for stroke patients

Conditions: Stroke; Malnutrition; Weight Loss; Dysphagia

Summary: prospective, short-term studies in patients admitted for acute stroke have shown an increased risk of infections, bedsores, impaired functional outcome, slower rate of recovery, poorer rehabilitation potential and higher mortality in patients with a poor nutritional status. in hospitals without routine nutritional assessment and individual nutrition management plans, the risk of patients developing malnutrition may be increased. in this study, patients admitted for acute stroke are randomised into either receiving nutritional therapy derived from estimated individual nutritional intake and nutritional needs, or nutritional therapy based on routine care without routine assessment of nutritional status, intake, or needs. the primary outcome measure is the percentage of patients with weight loss ≥ 5 % at three month follow-up.

prospective, short-term studies in patients admitted for acute stroke have shown an increased risk of infections, bedsores, impaired functional outcome, slower rate of recovery, poorer rehabilitation potential and higher mortality in patients with a poor nutritional status. sixteen percent of stroke patients are already malnourished on admission to hospital. the incidence of dysphagia in patients with acute stroke ranges from 30 to 45%. dysphagia increases the risk of developing poor nutritional status, and new cases of malnutrition develop during the hospital stay, even during the first week. in hospitals without routine nutritional assessment and individual nutrition management plans, the risk of patients developing malnutrition may be increased. in this study patients admitted for acute stroke are randomised into either receiving nutritional therapy derived from estimated individual nutritional intake and nutritional needs, or nutritional therapy based on routine care; without routine assessment of nutritional status, intake or needs. nutritional therapy: enriched meals, sip-feedings or enteral feedings. parameters of nutritional status: weight, bmi, tsf thickness, mid upper arm circumference, body composition, s-albumin and s-transferrin. estimation of nutritional intake: daily registration of food and drink intake. estimating functional status: hand grip strength, barthels adl index and scandinavian stroke scale. estimating quality of life: eq-5d. before the inclusion started we decided to use the percentage of patients with weight loss ≥ 5 % at 3 months follow-up as the primary outcome measure because this is correlated better to clinical outcomes as e.g. mortality and comorbidity. secondary outcome measures were then defined as handgrip strength, quality of life, nutritional status, nutrient intake and length of hospital stay.
