I have used EasyTrial as primary database for my clinical observation study for two years. I have collected both qualitative and quantitative data from several hundred patients. EasyTrial is also connected to a thermal printer, so we can print labels for vacutainer blood collector tubes directly from EasyTrial.
I consider it an advantage that EasyTrial meets the formal requirements for data protection and data storage. Being online based is a huge advantage, and I can't imagine using a paper-based or excel-based database. It is reassuring to know that data can't suddenly be lost since there's a backup, and it is difficult to accidentally delete larger amounts of information in the database unless you actively try. There's also no risk that data "blend together" as risked in an excel-sheet.
I think the system gives a good overview over project patients. It is easy to monitor the progress in data collection since I can always see how many percentages of the eCRF's are filled in for each participant. It has also been a great advantage for me that I can assign more or less limited access to other project staff and that all activity is logged. In addition, I find the system user friendly and easy to access, even from the beginning. My impression is that you can build the eCRF's to fit most types of studies.
In any case, I'm really pleased to have chosen EasyTrial for my study.
