For me, I have never conducted or seen clinical trial research collect data electronically in eCRF and using EDC software like my friends mentioned. It’s quite interesting to learn how benefit of having such technology to help manage the data. From my experience in clinics and my thesis, I simply collected data via paper-based questionnaires and then used the SPSS program for analysis. The data is only stored on my laptop and cloud drive, while hard copies of questionnaires were kept for two years and then destroyed. However, the questionnaires only had IDs assigned and didn’t contain identifiable personal data. Through the lectures in this course, I’ve gained a broader understanding of data management systems, which will be very useful for me as I planed to train to use the REDcap software in my workplace and aim to participate in more complex projects in the nearly future.
