Construction and Reliability and Validity Analysis of a Scale for Evaluating Sarcopenia in Hospital-ized Surgical Patients
[Objective]To construct a risk assessment scale for sarcopenia in surgical inpatients and conduct re-liability and validity tests,in order to provide a scientific and effective tool for assessing sarcopenia risk in surgical inpatients.[Methods]On the basis of literature review,a pool of items for the scale was constructed,and the con-tent system of the scale was determined through the Delphi method.The Analytic Hierarchy Process was used to determine the weights of scale items and assign values,forming a test scale.A test scale was used to assess the risk of sarcopenia in 239 patients admitted to the Hepatobiliary Department of Hunan Provincial People's Hospital,and the reliability and validity of the scale were tested.[Results]A total of 11 experts were consulted through 2 rounds of correspondence,and their positive coefficients were all 100％.The authority coefficients of the experts were 0.88 and 0.89,respectively.The Kendall harmony coefficients were 0.138 and 0.153(P＜0.001).A surgical inpatient sarcopenia risk assessment scale was constructed,including 5 primary indicators and 19 secondary indica-tors.The Cronbach's α coefficient of the scale was 0.829,and the content validity(I-CVI)of each item was 0.8-1.0,with a total content validity(S-CVI)of 0.99.Exploratory factor analysis extracted a total of 6 common fac-tors,with a cumulative variance contribution rate of 63.784％.The area under the curve(AUC)of the ROC scale was 0.74(95％CI:0.666-0.813,P＜0.001),the diagnostic threshold was 24 points,the sensitivity was 80％,and the specificity was 61.8％.[Conclusion]The constructed surgical inpatient sarcopenia risk assessment scale has certain scientific validity,practicality,and good reliability and validity,and can be used as a preliminary screening tool for clinical medical staff to evaluate the risk of sarcopenia in surgical inpatients.
