title: [Analysis of medical cost of atlantoaxial disorders in patients receiving innovated treatment technologies].
abstract: OBJECTIVE
  To explore the effects of innovated technologies and products on improving outcomes and decreasing medical costs by analyzing a total and subtotal medical costs of patients with atlantoaxial disorders.
  
  
  METHODS
  The medical costs of 1 489 patients with atlantoaxial disorders from Peking University Third Hospital from 2005 to 2014, who received innovated technologies and products treatment were retrospectively analyzed and compared.Descriptive analysis and ANOVA were used for statistical analysis, and SPSS 19.0 was used to analyze data.
  
  
  RESULTS
  From 2005 to 2014, under the situation of a general increase in medical cost by 327%, the total medical costs were stable for patients who used innovated technologies and products for treatment, fluctuating from 20 851 in 2005 to 20 878 in 2014; however, the cases of operation increased year by year, from 88 in 2005 to 163 in 2014; the average length of stay decreased from 21 in 2005 to 10 in 2014; the total cases of transfusion were 22 from 2005 to 2014; the safety, stability and feasibility of the innovated technologies and products were illustrated through the decrease of average length of stay, the reduction of bleeding and the significance of outcomes.
  
  
  CONCLUSIONS
  It is illustrated that the innovated technologies and products not only decrease patients' suffering and medical costs but also are safe, stable and feasible.
