<unk>  involves the administration of medication through a needle or catheter. Typically,<unk> " means that a drug is administered intravenously or subcutaneously. The term may pertain where drugs are provided through other non-oral routes of administration, such as intramuscular injection and epidural administration (into the membranes surrounding the spinal cord). Until the 1980s, patients receiving<unk>  often had to remain in an inpatient setting for the duration of their therapy. New technologies and heightened emphasis on cost containment in health care, as well as developments in the clinical administration of the therapy, led to strategies to administer<unk>  in alternate settings (at clinics and at home) in an effort to reduce hospital readmissions.
