Risk-adjusting Effect of DRGs on Birth Trauma Rate

Abstract：Objective To evaluate the adjusting effects of WI-DRGs on the birth trauma of newborns,and explore the effect of WI-DRGs on quality evaluation.Methods Birth traumas data from 3 hospitals from 2011 to 2016 were analyzed by univariate analysis and logistic regression to evaluate the effects of WI-DRGs and other factors.Results The overall birth trauma rate of newborn is 0.852‰.The univarate analysis shows that birth weight,puerpera's complication and comforbidity,and WI-DRGs have the statistical significant effects on the birth trauma of newborn.The expected counts of birth trauma of newborn are calculated by logistic regression,and the ratio of real counts to expected counts are 1.082,1.050 and 0.839 for 3 hospitals,respectively.Conclusion WI-DRGs is an effective quality evaluating tool.WI-DRGs,integrated with the NLP and QDM technology,can be used to build a comprehensive quality evaluation system for women and children specialty based on its application on birth trauma.Consequently,informationization comprehensive quality evaluation plafform will be developed and established.
