Reliability Of Longshi Scale With Remote Assessment Of Video Calls

Objective: The purpose of this study was to use Longshi assessment scale of activities of daily life(LSADL)to remotely assess the activities of daily living of stroke patients through video.The consistency between the remote assessment results and the on-site assessment results was compared,as well as the retest reliability of the remote assessment results,so as to determine the reliability of the remote assessment method of LSADL,and investigate the patient satisfaction,and explore its application value.Methods: A total of 150 stroke patients who were admitted to the Second People’s Hospital of Shenzhen and the Nanao People’s Hospital of Dapeng New District of Shenzhen from September to November 2021 and met the criteria of sodium intake were selected as the study objects.Demographic information and disease status of patients were collected at the time of enrollment.After enrollment,remote and on-site evaluations were carried out in random order,and the time spent in the two evaluation methods and the satisfaction with remote evaluation were recorded.A second remote video rating was performed in 51 patients to determine the retest reliability of the remote rating.weighted Kappa(w K)coefficient and Bland-Altman consistency analysis were used to determine the consistency of LSADL remote video rating and site rating results.w K was used to determine the retest reliability of LSADL remote video rating,and T-test was used to compare the time spent by the two evaluation methods.Results: A total of 150 eligible stroke patients were included in this study,but 21 were excluded due to various reasons such as loss of followup,and a total of 129 patients were finally included for statistical analysis,including 88 males,41 females,55 hemorrhagic stroke patients,and 74 ischemic stroke patients,with an average age of 64.5±15.6 years.Consistency analysis results showed that LSADL remote video evaluation results were highly consistent with field evaluation results(w K=0.86,95%CI: 0.80-0.92),and LSADL remote video evaluation results also had good retest reliability(w K=0.92,95%CI: 0.85-0.99).The time consuming of onsite evaluation was 80.45±65.42 s,and that of remote video evaluation was91.42±56.55 s.The T-test results showed that there was no statistically significant difference between the two evaluation methods(P=0.151).The satisfaction survey results showed that 85% of the subjects were satisfied or very satisfied with the remote evaluation.Conclusion: The remote assessment of Longshi Scale with smartphone video calls display with the evaluation of high consistency and retest reliability,has high credibility.At the same time,LSADL remote video assessment has no significant difference in time spent compared with the on-site assessment,and has good patient satisfaction,while the remote method has the advantage of distance.Therefore,this method can be used for remote assessment of stroke patients’ ability of daily living activities.
