| Object : To assess the nutritional status with MNA-SF and NRS2002 and to investigate its relationship to clinical prognosis in elderly inpatients and to investigate the nutrition supports they received.Methods: A total of 272 inpatients aged over 65 years in Health Care Center, Beijing Friendship Hospital were enrolled in this investigation from August 2014 to August2015.The nutritional status of all the participants were assessed with the Mini Nutritional Assessment Short-Form(MNA-SF) and Nutritional Risk Screening2002(NRS2002)within 72 h after admission.Those inpatients were divided into three groups according to age(65-74,75-84, ≥ 85), then compared their BMI,grip strength,walking speed,serum albumin and incidence of anomalotrophy(NRS2002scores≥3,MNA-SF scores≤11)of these three groups;The clinical outcomes of the participants(including hospital acquired infection, length of stay,and death) were observed prospectively.The relationship between nutritional status and clinical prognosis of these inpatients was analyzed and the nutrition supports they received were investigated. The relationship between nutritional status and chronic diseases of these inpatients was analyzed.Results: A total of 272 patients were enrolled.They were at the age(82.07±7.02)years.There were 163 cases(59.93%)at Normalized(MNA-N),78 cases(28.68%) at Malnutrition Risk(MNA-MR),and 31 cases(11.40%) at Malnutrition(MNA-M).According to the NRS2002 standard,There were 115 cases(42.28%) at Nutritional Risk(NRS-NR),157 cases(57.72%) at Normalized(NRS-N).With age increasing,the commonly used nutritional indicators BMI,gripstrength,walking speed,serum albumin shrinked gradually,statistically significant with complete group differences.The NRS2002 nutritional(≥3 scores)risk rate rose with age increasing, with statistically significant difference(P < 0.05). the MNA-SF incidence of anomalotrophy(≤11 scores)rose with age increasing, with statistically significant difference(P<0.01).The incidence rate of hospital acquired infection in MNA-M group were higher than that in MNA-N group(P < 0.01),The lengths of stay in MNA-M group and MNA-MR group was both longer than that in MNA-N group(P<0.01), Nine of 272 participants died during hospitalization, and five among them were in MNA-M group,The rate of mortality in MNA-M group was significantly higher than that in MNA-N group(P<0.01);The incidence rate of hospital acquired infection in NRS-NR group were higher than that in NRS-N group(P< 0.05),The lengths of stay in NRS-NR group was longer than that in NRS-N group(P<0.01).Nutritionl support was provided to 20 patients of all the participants,to 12 patients(38.7%) at MNA-M group.The average enteral nutrition: parenteral nutrition ratio was 5.67: 1.The top nine chronic diseases of all the participants were hypertension disease,coronary heart disease,hypertension,type 2 diabetes, cerebrovascular disease,osteoporosis, constipation, gastroesophageal reflux disease, dementia.Compared with no malnutrition group, the morbidity rate of dementia rose significantly in MNA-M group, with statistically significant difference(P<0.01),. the morbidity rate of other chronic disease had no statistical difference between the two groups.Conclusions: In elderly inpatients,the commonly used nutritional indicators BMI,muscle strength,serum albumin decreased with age increasing.Using the eveluation NRS2002 and the MNA-SF, the incidence of anomalotrophy rose with age increasing. Malnutrition status or having nutrition risk increases the incidence ofhospital acquired infections, length of stay, and mortality risk. The application of nutritional support currently is more reasonable than before,however,its standard degree needs to be improved. Dementia patients more easily suffered with malnutrition, and clinical doctors should pay attention to the nutritional status of dementia patients. |
