Objective  To construct a nursing quality evaluation indicator system for the prevention of acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods  Based on the model of the "Structure-Pro-cess-Result",this  study  combined the  methods  of  literature  analysis, semi-structured  intemiews,Delphi  method  and analytic  hierarchy process to  determine the  weight of  each  index and constructed the  COPD nursing quality evalnation indicator system.  Results   The positive coefficients of the two  rounds of expert inquiries respectively were 92.31%  and  95.83%.  The  authoritative  coefficients  of  experts  were  0.769  and  0.895,and the  coordination  coeffidents respectively were 0.121  and 0.204. This nursing quality evaluation indicator system consisted of 3 first-level indicators, l2  second-level  indicators,and 53  third-level indicators. The  weight coefficients of  each  level indicators were established.  Conclusion  This indicator system reflects the characteristics of  COPD  and has  a clear hierarchy,accurate evaluation indicators,and reasonable weight distribution. It  builds   a foundation for further empirical research.
