Predictive Value of Serum Alb,Mb,MEWS and Waterlow Scores for Pressure Injury in Intensive Care Unit Patients
Objective:To explore the predictive value of serum albumin(Alb),myoglobin(Mb),modified early warning score(MEWS)and Waterlow score for pressure injury(PI)in intensive care unit(ICU)patients.Methods:120 patients who were hospitalized in the ICU of the People's Hospital of Xinjiang Uygur Autonomous Region from June 2021 to December 2022 were selected,patients were divided into PI group(43 cases)and non-PI group(77 cases)according to whether PI occurred.The influencing factors of PI in ICU patients were analyzed by multivariate Logistic regression analysis,the predictive value of serum Alb,Mb,MEWS and Waterlow scores for PI in ICU patients was analyzed by receiver operating characteristic(ROC)curve.Results:The age in PI group was higher than that in non-PI group,the proportion of mechanical ventilation,body temperature,Mb,MEWS and Waterlow scores were higher than those in non-PI group,the length of hospital stay was longer than that in non-PI group,and Alb was lower than that in non-PI group(P＜0.05).Prolonged hospitalization time and elevated Mb,increased MEWS,and increased Waterlow score were independent risk factors for PI in ICU patients,and elevated Alb was an independent protective factor(P＜0.05).The area under the curve of serum Alb,Mb,MEWS and Waterlow score in predicting PI in ICU patients was greater than that predicted by each index(P＜0.05).Conclusion:The decrease of serum Alb level and the increase of Mb,MEWS and Waterlow scores are independently correlate with PI in ICU patients,the combination of serum Alb,Mb,MEWS and Waterlow scores has good predictive value for PI in ICU patients.
