Clean data one click away: using back-end library rules to clean on SDTM datasets

Data in clinical trials comes from various sources and consequently takes different formats: (e)CRF systems, external vendor data, questionnaires, etc. The variability of this data makes it hard to define, validate and implement standard rules for data cleaning and reconciliation.

Using SDTM datasets during a study for data cleaning, allows the creation of a library of standard electronic rules that can be configured without the need for programming by a clinical data manager.

In this presentation we will demonstrate how this library of rules is used and maintained by sharing practical examples of a case study. We will start with the workflow how to select standard rules from the library and configure them for a specific clinical study. In the next step, the addition of study specific rules is reviewed. The case study ends with the process for the inclusion of a new study specific rule to the overall standard library. The benefits and drawbacks of this system conclude the presentation.
