Objective: Openclinica Input Completion (OIC) was developed to increase the efficiency to enter drugs in eCRF in OpenClinica^®. The aim of the study was to evaluate the impact on efficiency and data quality as well as usability.

Methods: 20 participants were asked to input 15 drugs with the new tool and by hand.

Results: The mean input time got decreased from 16:12m to 3:59m. 31 of 300 (10%) of manual entered medication data sets had one or more errors versus 10 of 300 (3,3%) data sets entered with OIC.

Conclusion: OIC was able to increase efficiency and data quality. We conclude that new additions to the graphical user interface in electronical Case-Report-Form (eCRF) systems should be validated before usage in research projects.
