Abstract:Objective To explore the application effect of precision nursing based on evidence-based concept in elderly patients with sarcopenia. Methods From October 2018 to June 2020, a total of 177 elderly patients with sarcopenia who were admitted to the Affiliated Hospital of Nanjing University Medicine School were selected as the research subjects. According to random number table method, they were divided into control group (89 cases) and observation group (88 cases). The control group was given routine sarcopenia nursing intervention, and the observation group was given precision nursing intervention based on evidence-based concept on the basis of the control group, and the intervention time was 12 weeks. The skeletal muscle index (SMI), muscle function grade and short physical performance battery (SPPB), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and intervention satisfaction rate of the two groups were compared before and after intervention. Results After intervention, there was no statistical significance in SMI, muscle function grade and SPPB score of control group compared with before intervention (P > 0.05). SMI, muscle function grade and SPPB score of the observation group were higher than before intervention, and the observation group was higher than the control group, the differences were statistically significant (P < 0.05). SAS and SDS scores in both groups were lower than those before intervention, and observation group were lower than those of control group, the differences were statistically significant (P < 0.05). The total satisfaction rate of intervention in the observation group was higher than that in the control group, with statistical significance (P < 0.05). Conclusion Precision nursing based on the evidence-based concept can significantly improve the psychological status and muscle function attenuation of elderly patients with sarcopenia, and improve the satisfaction rate of intervention, which is worthy of promotion and application.
