The Study Of Diagnosis Related Groups System In Three Hospital Of Ningxia

Objective The aims of my thesis are as follows: applied in the dischargedpatients’ medical records information of the largest number of30kinds of diseasesin Ningxia representative three tertiary hospital (the first people’s hospital ofYinchuan, Ningxia medical university general hospital, the autonomous regionpeople’s hospital) in2010-2011, validating the result of the group research, to explorediagnosis related group effect, and to shift the cost of medical services tohospitalization.Methods This article adopted methods of single factor analysis, statisticaldescription, rank and inspection and multiple linear regression method;combinationof document information, the mix group axis through combing hypothesis (that is,the classification of the dependent variable) and grouping variable (that is, theinterpretation of the classification variables); the single factor analysis and multiplefactor analysis method to determine the main factors influencing the cost and thegrouping variable; CHAID Clementine12.0decision tree classification; ROC curve;the variation coefficient; Kruskal Wallis rank and inspection etc. Nonparametricmethods validation group results.Results The main reasons influencing the hospitalization expenses are: operation,complication, gender, age section, on admission.30kinds of diseases,40000caseswere divided into202diagnosis related groups. Combination of different diseases ofvariation coefficient is96.5%less than1, indicate that the homogeneity within group is better; Nonparametric rank and inspection according to the combination betweenthe P value is less than0.05, the difference was statistically significant between casemix. Case mix before groups of expenses and the classification of the cost of thedifference was statistically significant, and according to the different disease situationgives off a combination of standard cost is less than the standard cost of the originaldisease. Through the analysis of the costs of medical insurance in the insurance cost ishigher than out-of-pocket medical costs.Advice1. In the case group, strengthen the standardization of disease diagnosis classification2. Applied disease to health care costs, to a certain extent, provide a certain basis formedical insurance3. According to the ICD-10standard disease diagnosis and coding, strengthen theconstruction of hospital informatization4. Combined with the medical insurance, formulate the corresponding incentivemechanism...
