In a matter of hours, you can create an eCRF that is just as easy to use and as simple as a paper one. This will help you avoid the most common problems in data collection for Pre-authorisation and post-authorisation studies. When creating an eCRF, make sure you have an EDC that is flexible. This will allow you to adapt to any type of study. The EDC includes a number of monitoring and management tools that will help you save a lot of time and effort in managing and monitoring the study. You should use a valid system that gives trust to the sponsor and allows for the collection of high quality data. Do not wait until the analysis phase to find errors in the data. Otherwise, you will have to chase down investigators to correct them. Avoid making the process of creating an eCRF long and complicated.
