Prevalence of nutritional risk and malnutrition and observation of nutritional intervention in hospitalized patients with stroke in a teaching hospital in Beijing

Objective To investigate the prevalence of nutritional risk(NRS2002) and malnutrition in hospitalized stroke patient and their nutritional intervention. Methods The stroke patients admitted to three departments of vascular neurology ward including cerebral hemorrhage, cerebral infarction and subarachnoid hemorrhage in Beijing Tiantan Hospital from January 2018 to January 2019 were recruited using cluster sampling. Nutritional risk screening 2002 (NRS 2002) was used to screen the nutritional risk of inpatients Malnutrition was assessed by criteria: (1)body mass index (BMI) <18.5 kg/m2 with poorer general condition from January 2018 to January 2019; (2)Global leadership initiative on malnutrition(GLIM)criteria were used except whole body muscle mass measurement from October 2018 to January 2019. The nutritional intervention for patients were closely observed during hospitalization. Results A total of 1 532 patients were registered and 1 036 patients were included in the final analysis considering the inclusion and exclusion criteria.The prevalence of nutritional risk was 33.0%(342/1 036). The prevalence of malnutrition based on BMI and GLIM criteria was 0.9% (9/1 036) and 2.5% (10/393) respectively. Among the 342 patients with nutritional risk, 112 patients received nutritional support therapy by tube feeding, but only 29 patients received nutritional support that met guideline standards.81 patients received not standard nutritional support, and 2 patients received highly unregulated nutritional support. No patients received sugar and electrolyte infusion, oral nutritional supplements (ONS), oral nutritional agents and compound nutrition intervention. The other 230 patients took hospital diet. Conclusion The prevalence of nutritional risk in hospitalized patients with cerebral hemorrhage, cerebral infarction or subarachnoid hemorrhage was high, and the prevalence of malnutrition was extremely low. There was a low proportion of nutritional support.High quality of large sample cohort studies will be conducted to show whether reasonable application of nutritional support therapy in patients with nutritional risk can improve patient outcome.
