Behandelnde
Behandelnde is a German term meaning "the person who treats" and is used as a noun to designate the clinician or healthcare professional responsible for a patient’s medical treatment. It originates from the verb behandeln (to treat) with the agent suffix -nde and is commonly capitalized in formal writing. In practice, the Behandelnde may be a physician, psychotherapist, dentist, nurse with therapeutic duties, or any licensed health care provider who delivers treatment and makes therapeutic decisions.
The term is largely role-based rather than a fixed professional title; it identifies the person in charge
In English contexts, Behandelnde is commonly translated as "the treating physician/clinician" or "the treating health professional."
