or medical condition, especially when prescribed or chosen rather than resulting from severe prostration or imminent death. Even though most patients in hospitals spend most of their time in the hospital beds, bed rest more often refers to an extended period of recumbence at home. Some clinicians now regard bed rest as being at best neutral to outcome, and in some cases potentially harmful to patients.
