Application of modified early warning score and calibrated modified early warning score in surgical in-patients

Objective:To compare the application of modified early warning score(MEWS)and calibrated MEWS in surgical inpatient care.Methods:The MEWS and calibrated MEWS of 171operation patients at the time of hospitalization in surgical ward were analyzed retrospectively.Results:The incidence of automatic discharge or death or transferred to ICU increased significantly in patients of higher MEWS and calibrated MEWS.The difference had statistical significance compared with lower grade(P0.01).Transferred to ICU as predictor,the MEWS assessment boundary value was 4,the sensitivity was 54.5%,specific degree was 90.6%,the area under the ROC curve was(0.878±0.030)(95%,0.848~0.848,P= 0.000);while Calibrated MEWS assessment boundary value was 5,sensitivity was 59.1%,specific degree was 89.3%,the area under the ROC curve was(0.907±0.023)(95%,0.884~0.884,P=0.000).Conclusion:Comparing with MEWS, Calibrated MEWS can reflect the degree of postoperative surgical patients in a critical condition,improve the monitoring level of the trigger point and easy to get by nurses.It is worth popularizing and applying in the surgical ward.
