It depends upon what you want to get out of it, because not all clinical research experiences are the same.
The best ones will be where you have actual patient contact experience, and are doing something with and/or for the patients, other than enrolling them. For example, taking BPs or other vitals is a good thing.
The worst is where you're just doing logistical stuff. Calling them up and enrolling them or reminding them of their app'ts is dealing with research subjects, not patients.
That's the clinical part. Now for the research, if you're learning about the scientific method and testing a hypothesis, that's all good. You just crunching numbers isn't all that good.
