Tertiary referral hospital

A tertiary referral hospital (also called a tertiary hospital, tertiary referral center, or tertiary care center, or tertiary center) is a hospital that provides tertiary care, which is health care from specialists in a large hospital after referral from primary care and secondary care. Beyond that general definition, there is no precise narrower or more formal definition, but tertiary centers usually include the following:

a major hospital that usually has a full complement of services including pediatrics, obstetrics, general medicine, gynecology, various branches of surgery and psychiatry or
a specialty hospital dedicated to specific sub-specialty care (pediatric centers, Oncology centers, psychiatric hospitals). Patients will often be referred from smaller hospitals to a tertiary hospital for major operations, consultations with sub-specialists and when sophisticated intensive care facilities are required.
Some examples of tertiary referral center care are:

Head and neck oncology
Perinatology (high-risk pregnancies)
Neonatology (high-risk newborn care)
PET scans
Organ transplantation
Trauma surgery
High-dose chemotherapy for cancer cases
Growth and puberty disorders
Neurology and neurosurgery
In the UK, cases of poisoning.
