Abstract:

Objective

To develop an evaluation index system of assessing data management for investigator-initiated trial (IIT), so as to provide an objective and operable basis for scientific evaluation.

Methods

Using the Delphi method, 23 experts were invited to conduct 2 rounds of correspondence to rate the importance of each proposed indicator in the evaluation system. The index system was assessed based on expert's response rate, authority coefficient and opinion coordination degree, with final modifications incorporating experts feedback.

Results

In the 2 rounds of consultation, the positive coefficient of experts were both 100%, the credibility ratio were 0.899 and 0.890 respectively, and the Kendall's W coefficient were 0.247 and 0.375, respectively. The finalized evaluation system comprises 3 first-level indicators, 14 secondlevel indicators and 52 third-level indicators.

Conclusion

The evaluation index system based on Delphi method in this study demonstrates good reliability and practicality for assessing IIT data management.

Key words: Delphi method, investigator-initiated trial, data management, evaluation index
