Objective To establish the efficacy evaluation index system for chronic obstructive pulmonary disease （COPD） in stabilization period based on expert questionnaire. Methods The expert questionnaire was designed and 50 experts were investigated. The questionnaires were collected to establish a database. The Delphi method was used. The concentration degree of expert opinions was evaluated with mean and full mark rate. The outcome indicators were empowered with percentage weighting method. Results Fifty questionnaires were sent out and 50 questionnaires were returned. The expert active factor was 100%. The efficacy evaluation index system for COPD in stabilization period included clinically relevant indicators

quality of life

laboratory parameters

pattern related indicators

economic indicators and comprehensive evaluation. The relatively concentrated evaluation index of expert advice （mean≥4.5 points） was acute exacerbations

forced expiratory volume in one second

wheezing

BODE index

readmission rates

forced expiratory volume in one second and forced vital capacity ratio

partial pressure of carbon dioxide

St. George’s Respiratory Questionnaire （SGRQ）

acute exacerbation interval and acute increased severity. The relatively concentrated evaluation index of expert advice （weight≥0.017） was patterns related indicators

economic indicators

BODE index

SAFE index

smallest changes in the value of clinical significance

SGRQ

pulmonary function and dyspnea questionnaire

Quality of Life Scale for Lung Disease and Pulmonary Status Scale. Conclusion The efficacy evaluation index system for COPD in stabilization period based on expert questionnaire includes indicators of medical attention

indicators of patient attention

laboratory parameters and TCM pattern related indicators.
