Evaluation of the value of internet intelligent guidance for out-of-hospital functional exercise in patients with arteriovenous fistula based on DID model

目的探讨基于双重差分法(DID)模型评估互联网智能指导用于动静脉瘘患者院外功能锻炼的价值。方法前瞻性选取2020年1月至2021年3月该院收治的动静脉内瘘患者62例,按照随机数字表法分为智能组和常规组,各31例;常规组予以常规指导院外功能锻炼,智能组予以互联网智能指导院外功能锻炼。观察两组动静脉内瘘功能、自我管理能力及生活质量水平,并采用DID模型对比两组干预前后不同时间点(干预前和干预1、3、6个月)引流静脉血流量及自我管理能力。结果干预1、3、6个月后,两组引流静脉血流量及直径均增大,自我管理能力评分、生活质量评分均升高,且智能组均明显高于常规组(P<0.05);DID回归模型显示,引流静脉血流量和自我管理能力在干预效应和时间效应上均差异有统计学意义(P<0.05)。结论互联网智能指导用于动静脉瘘患者院外功能锻炼中,可改善患者动静脉瘘功能,强化自我管理能力,提高生存质量。

Objective To evaluate the value of internet intelligent guidance for out-of-hospital functional exercise in patients with arteriovenous fistula based on the difference-in-difference(DID)model.Methods A total of 62 patients with arteriovenous fistula admitted to this hospital from January 2020 to March 2021 were prospectively selected and divided into the intelligent group and the conventional group according to the random number table method,with 31 cases in each group.The conventional group was provided routine guidance for out-of-hospital functional exercise,and the intelligent group was provided internet intelligent guidance for out-of-hospital functional exercise.The arteriovenous fistula function,self-management ability and quality of life of the two groups were observed,and the DID model was used to compare venous blood flow and self-management ability of the two groups at different time points before and after intervention(before intervention,1,3 and 6 months after intervention).Results After 1,3 and 6 months of intervention,drainage venous blood flow and diameter,self-management ability score and quality of life score increased in both groups,and the above indicators in the intelligent group were significantly higher than those in the conventional group(P<0.05).The DID regression model showed that drainage venous blood flow and self-management ability had statistical significance in intervention effect and time effect(P<0.05).Conclusion The use of internet intelligent guidance in out-of-hospital functional exercise for patients with arteriovenous fistula can improve the function of arteriovenous fistula,strengthen their self-management ability,and improve the quality of life.
