Going to give a brief summary of the general job responsibilities of a CRA. CRAs is health-care professional who performs many activities related to medical research. Some of those activities can be keeping the GCP’s for monitoring the clinical trials taking place, reviews case report forms (CRFs), communicates with clinical research coordinators, basically a manager as it were. With those tasks listed above and what asimbana has stated it is mandatory for a CRA to have clinical background experience prior to being a CRA. In contrast, if say you’re a statistician having clinical experience is not a must in my opinion. You can and should be able to hire a bioinformatic with a 4 year degree to be able to do the work. Also, the people of the company I am sure have someone who has experience with data collection and how to interpret the data before them therefore, they can help the new employee with such a task.
