【摘要】 目的调查不同骨关节病老年住院患者的营养状态,分析其与住院时间和医疗费用的相关性。方法应用微型营养评定精法(MNA-SF),前瞻性调查2012年4月至2012年5月因患各种骨关节疾病入院的老年患者的营养不良和营养不良危险发生率,并分析其与临床结局的相关性。结果纳入各类骨关节疾病老年患者316例,平均年龄(74.98±5.67)岁,体质指数23.38±2.89;除3例少见骨关节疾病外,上臂围(25.79±3.04)cm、小腿围(31.99±3.29)cm、利手握力(17.57±14.50)kg。313例完成MNA-SF,12.5%存在营养不良,35.5%有营养不良危险;不同骨关节病老年患者营养不良和营养不良危险发生率不一致,其中类风湿性关节炎患者握力最低(6.78±7.31)kg和营养不良率最高(27.3%)。306例纳入营养状态与临床结局分析,与营养正常者比较,营养不良者的住院时间更长[(14.03±2.44)d vs(9.68±5.37)d],住院费用较高[(2.96±0.78)万元vs(2.21±1.74)万元],差异均有统计学意义(P<0.05)。结论老年骨关节疾病住院患者营养不良和营养不良危险发生率较高,并可导致住院时间延长和医疗费用增多。更多还原

【Abstract】 Objective To describe the nutritional status in elderly patients with benign orthopaedic disease and assess the impact of nutritional status on clinical outcomes. Methods Elderly patients with benign orthopaedic disease were enrolled in a prospective study during April 2012 to May 2012. Short-form mini nutritional assessment( MNA-SF) was used to assess the nutritional status. Associations between nutritional status and clinical outcomes were sought. Results Among 316 patients,the average age was( 74. 98 ± 5. 67) years old,body mass index was 23. 38 ± 2. 89. In addition to 3 cases of bone and joint disease,the upper arm circumference was( 25. 79 ± 3. 04) cm,mean calf circumference was( 31. 99 ±3. 29) cm,and mean grip strength was( 17. 57 ± 14. 50) kg,313 patients completed the MNA-SF,12. 5%were malnourished,35. 5% were at risk of malnutrition. Patients with different kinds of osteoarthrosis changed in nutritional status,patients with rheumatoid arthritis had a lower grip strength( 6. 78 ± 7. 31) kg and a higher rate of malnutrition( 27. 3%). Compared with normal nutrition,significantly longer hospital stays(( 14. 03 ± 2. 44) d vs( 9. 68 ± 5. 37) d) and higher hospitalization costs(( 2. 96 ± 0. 78) million yuan vs( 2. 21 ± 1. 74) million yuan) among those patients who were malnourished were found,the differences were statistically significant( P < 0. 05). Conclusion Elderly patients with benign orthopaedic disease have a high prevalence of malnutrition and nutritional risk assessed by MNA-SF. Poor nutritional status is associated with worse clinical outcomes.更多还原
