Initial Care Team

When a patient is brought to Jamaica Hospital Medical Center, the severity of injury is assessed immediately by the Trauma Team. The trauma surgeons and nurses are the primary team responsible for the surgical evaluation, care and plan of medical treatment. The way they work behind the scenes is a process designed to better help patients by making sure critical care is delivered safely and timely so that all the patient needs are met.

To meet the individual needs of that injured patient, while coordinating efforts with the family if available at that time, these trauma surgeons and nurses work as a collaborative team. Other medical specialists also may participate in care of the injured patient, as necessary. These providers may be from different surgical or non-surgical specialties. This includes the decision when to use diagnostic evaluative tools like Ultrasound scans, CT or X-ray, etc. and in what order to provide different pieces of the care plan, called the sequencing of care.
