That's quite possible, but it depends on the particular clinical trial, and also on the level of care you -- or the person you're caring for -- is currently receiving. Typically, participation in a clinical trial requires very close monitoring, including lots of tests and personal attention from researchers who may be top specialists in their field.
On the other hand, researchers in a trial are naturally focused closely on the effects of the drug or method they're testing. They may not be as focused on monitoring patients' overall health and well-being, coordinating other treatments, and offering help in dealing with side effects and lifestyle issues.
