title: [Subject analysis of direct medical cost on pneumoconiosis patients with electronic records in an iron & steel enterprise].
abstract: OBJECTIVE
  To study the distribution of the direct medical cost for the pneumoconiosis and to provide the clue for the trauma insurance.
  
  
  METHODS
  936 cases including 109,530 records were divided into several groups by the stages of pneumoconiosis and categories of the cost. The groups (stage I, stage II, stage I with tuberculosis and stage II with tuberculosis) were analyzed by descriptive statistics and non-parameter test.
  
  
  RESULTS
  The medical cost of out-patient clinic was between 476.7 and 2307.9 yuan per patient per year. The hospitalization medical cost of stage I and II ranged from 3207.1 yuan to 7787.3 yuan per patient per year. There was no difference between stage I and II in statistically significant (P>0.05).
  
  
  CONCLUSIONS
  The lower and upper inter-quartile range of the total medical cost per patient per year is from 3207.1 yuan to 7787.3 yuan. In the categories of the hospitalization cost, drugs and bed fees attain a higher proportion.
