Abstract:
Objective To improve the phacoemulsification (PHACO) technical level and management level for hospitals and to support the health decisions of health administration departments , we establish an index system of PHACO quality control of Guangdong province. Methods We determined the critical value , screened indicators and calculated the weight value with a method of literature analysis , Dephi method , percentile method, correlation coefficient and so on. At last, we tested the content validity through literature research and expert opinions and tested construct validity of the indicator system using factor analysis. Results An index system of PHACO assessment of 5 first grade indicators , 11 second grade indicators and 20 third grade indicators was established. Reliability analysis showed that three rounds of positive coefficient were 80.00%, 90.00% and 92.59%. Experts' authority coefficient was ranged from 0.710 to 0.921. Coefficient of concordance were 0.400 , 0.395 and 0.278 (P < 0.01). The standardized Cronbach α was 0.837 and the construct validity was good. The corresponding rate between simulation results and expert assessment was 94.55%. Conclusions It is reasonable and practical to use Delphi method to construct the index system of PHACO assessment. Reliability and validity of the index system and empirical application indicate the feasibility of its practical application.
