U-center is an "open" clinic and does not have a closed ward. When there is confusion or psychosis, U-center may not be able to provide adequate protection and safety. With severe crisis sensitivity, it is often better to stabilize first in another setting. For some conditions, U-center is less suitable because a longer treatment time will be required, for example, chronic psychotic syndrome (schizophrenia) or bipolar disorder. Some people are less able to function in groups, for example, because of certain personality disorders or aggression issues. Some addictions, such as GHB, lend themselves less to U-center's treatment setting.
