个性化饮食护理干预对老年慢性心力衰竭患者预后情况及MNA、 MNA-SF评分的影响

Effect of individualized diet nursing intervention on prognosis, MNA and MNA-SF scores of elderly patients with chronic heart failure

目的探究并分析个性化饮食护理干预对老年慢性心力衰竭患者预后情况及MNA(微型营养评分)、MNA-SF(改良版微型营养评分)评分的影响.方法选取该院自2016年2月~2017年2月收治的老年慢性心力衰竭患者100例,按照随机数字表法分为观察组和对照组,每组50例.对照组患者给予常规护理干预,观察组患者在对照组患者基础上给予个性化饮食护理干预,观察并记录两组患者干预前后血清白蛋白及血清前白蛋白、干预前后MNA-SF及MNA评分、住院指标及疗效.结果干预前两组患者血清白蛋白比较,差异无统计学意义(P>0.05),干预后两组患者血清白蛋白明显高于干预前(P<0.05),但观察组血清白蛋白明显高于对照组(P<0.05);干预前两组患者血清前白蛋白比较无明显差异(P>0.05),干预后两组患者血清前白蛋白明显高于干预前(P<0.05),但观察组血清前白蛋白明显高于对照组(P<0.05);干预前两组患者MNA-SF比较无明显差异(P>0.05),干预后两组患者MNA-SF明显高于干预前(P<0.05),但观察组MNA-SF明显高于对照组(P<0.05),具有统计学意义.干预前两组患者MNA比较无明显差异(P>0.05),干预后两组患者MNA明显高于干预前(P<0.05),但观察组MNA明显高于对照组(P<0.05);观察组患者住院时间、再入院率、病死率等均明显低于对照组(均P<0.05),而再入院时间明显高于对照组(P<0.05);经秩和检验,两组患者疗效比较,差异有统计学意义(U=9.438,P=0.000),观察组患者总有效率明显高于对照组,差异有统计学意义(χ2=5.761,P=0.007).结论个性化饮食护理干预能有效改善老年慢性心力衰竭患者营养状态、并改善预后情况、MNA及MNA-SF评分.

Objective To explore and analyze the effects of individualized dietary nursing intervention on prognosis and MNA (Mini Nutritional Score) and MNA-SF (Modified Mini Nutritional Score) score in elderly patients with chronic heart failure. Methods A total of 100 elderly patients with chronic heart failure admitted to our hospital from February 2016 to February 2017 were selected and divided into observation group and control group according to random number table, 50 cases in each group. Patients in the control group were given routine nursing intervention, patients in the observation group were given personalized diet nursing intervention on the basis of patients in the control group.Serum albumin and prealbumin, MNA-SF and MNA scores, hospitalization indexes and efficacy were observed and recorded in the two groups before and after intervention. Results There was no significant difference in serum albumin between the two groups before intervention (P>0.05). Serum albumin of the two groups was significantly higher after intervention than before intervention (P<0.05). However, serum albumin in the observation group was significantly higher than that in the control group (P<0.05). There was no significant difference in serum prealbumin between the two groups before intervention (P>0.05). Serum prealbumin was significantly higher in the two groups after intervention than before intervention (P<0.05). However, serum prealbumin in the observation group was significantly higher than that in the control group (P<0.05). There was no significant difference in MNA-SF between the two groups before intervention (P>0.05). MNA-SF was significantly higher in the two groups after intervention than before intervention (P<0.05). However, MNA-SF in the observation group was significantly higher than that in the control group (P<0.05), with statistical significance. There was no significant difference in MNA between the two groups before intervention (P>0.05). MNA of the two groups was significantly higher after intervention than before intervention (P<0.05). However, MNA in the observation group was significantly higher than that in the control group (P<0.05). The length of stay, readmission rate and mortality in observation group were significantly lower than those in control group (P<0.05), while the readmission time was significantly higher than the control group (P<0.05). After rank-sum test, the difference between the two groups was statistically significant (U=9.438, P=0.000). The total effective rate of the observation group was significantly higher than that of the control group, and the difference was statistically significant (χ2=5.761, P=0.007). Conclusion Individualized dietary nursing intervention can effectively improve nutritional status, prognosis, MNA and MNA-SF scores of elderly patients with chronic heart failure.
