Abstract:
0bjective:To explore the responsiveness and minimal clinical significance difference(MCID)of the Chinese version of the Chelsea critical care physical assessment tool(CPAx),the Perme Score intensive care unit mobil-ity score(Perme Score),and the intensive care unit(ICU)mobility scale(IMS)for patients in ICU during the early-stage rehabilitation,providing more comprehensive evidence support for clinical application of these scales.Method:It is a prospective observational study.The convenience sampling method was used to select 114 pa-tients in a ICU of a Tertiary Hospital in Shanghai from March 2021 to December 2021.Patients were as-sessed by Chinese version of CPAx,Perme Score,and IMS before the first rehabilitation treatment and within 24 hours before discharge from ICU.Likert five-scale was used to evaluate the overall changes in health sta-tus of the patients after the last rehabilitation.Responsiveness includes both internal responsiveness and exter-nal responsiveness.Internal responsiveness was determined by pair t-test,effect size(ES)and standardized re-sponse mean(SRM);external responsiveness was assessed by using Spearman correlation coefficient.MCID was calculated by integrating the estimates from the distribution-based methods and the anchor-based methods.Result:Internal responsiveness outcomes indicated that there was significant difference between the score of CPAx,Perme Score and IMS before and after rehabilitation(P<0.05),with ES of 1.03,1.09 and 1.14,and SRM of 1.75,1.52 and 1.73,respectively.The results showed that the scale had good internal responsiveness and could sensitively reflect the changes of patients'condition.External responsiveness outcoms showed that Spearman correlation coefficients of CPAx,Perme Score and IMS with global rating of change(GRC)were 0.67,0.50 and 0.30,respectively(P<0.01),indicating that apart from IMS,the other scales had good external reactivity,and could reflect the changes of patients'self-perception during the rehabilitation process.The MC-ID of CPAx scale with ES as the intermediate index is 5.66,SEM is 5.48,self-therapeutic effects is 8.73.The MCID of Perme Score with ES is 2.43,SEM is 3.64,self-therapeutic effects is 5.00.The MCID of IMS scale with ES is 1.28,SEM is 2.01,self-therapeutic effects is 2.43.Conclusion:Except for the lack of external responsiveness of IMS,the other Chinese version scales had good internal and external responsiveness in early-stage rehabilitation of ICU patients.Combined with the litera-ture review and the actual situation of using the scale in the study,the mean values of distribution method and criterion method were taken to preliminarily determine that the MCID of Chinese version of CPAx,Perme Score and IMS in ICU early rehabilitation were 6.62,3.69 and 1.90,respectively.
