When a person diagnosed with ED and under specialist monitoring has an unfavorable evolution of the disorder, with loss of functionality and inability to maintain stability in community resources, admission to subacute hospitalization units that respond to a high-intensity, interdisciplinary therapeutic intervention, but without high life risk, may be suggested, in which case admission to acute units would be indicated.

That is, acute hospitalization care units treat cases with a high vital or behavioral risk, while subacute hospitalization units treat cases that require in-depth investigation into the causes of the disorder and have a moderate/high risk of complications.
