About UCLA Health

UCLA Health is among the most comprehensive and advanced health care systems in the world. Our mission is to provide state-of-the-art patient care, generate research discoveries leading to new treatments and diagnoses, and train future generations of health care professionals. Together, the UCLA Hospital System and the David Geffen School of Medicine at UCLA strive every day to be a leader in setting the standards of excellence.

For 36 consecutive years, UCLA Health hospitals have earned a place on the U.S. News & World Report national honor roll, a distinction reserved for only 20 hospitals or health systems providing the highest-quality care across multiple medical specialties. In 2025, U.S. News ranked UCLA Health #1 in both California and in Los Angeles*.

UCLA Health consistently performs well in a variety of other assessments of quality and safety conducted by independent publications, accreditation bodies, advocacy groups and disease-specific organizations using a wide range of methodologies.

As an academic health system, UCLA Health offers access to technology and treatments that may not be available elsewhere. Our physicians are world leaders in the diagnosis and treatment of complex illnesses.

UCLA Health doctors and scientists are pioneering work in an astounding range of disciplines – from organ transplantation and cardiac surgery to neurosurgery and cancer treatment – and are bringing the latest discoveries to virtually every field of medicine.

Innovation and Research

Faculty continues to power progress in a wide range of disciplines. Our physicians, scientists and health care professionals are helping to transform medical care.

New Cancer Drugs Developed

UCLA research has paved the way toward new treatments that have changed cancer care and improved patient prognoses.

UCLA Health Jonsson Comprehensive Cancer Center members have led clinical trials or made other major contributions to the development of 27 new cancer treatments and protocols approved by the FDA, most of them since 2014.

• Herceptin (trastuzumab) — for a particularly aggressive subtype of breast cancer.
• Xtandi (enzalutamide) and Erleada (apalutamide) — for late- and early-stage prostate cancer.
• Ibrance (palbociclib) — for a different type of breast cancer and used in combination with hormonal
  therapy.
• Gleevec (imatinib) — for two different forms of leukemia.
• Keytruda (pembrolizumab) — for both melanoma and lung cancer.
• Yescarta (axicabtagene ciloleucel) — genetically engineers a patient’s white blood cells (CAR-T cell therapy) to treat a type of lymphoma that has returned or stopped responding to other therapies.

Center of Excellence in Solid Organ Transplants

Scientific innovation by faculty has advanced organ transplantation, saved lives and helped make UCLA Health a national leader in the field.

• Developed a tissue-matching test that made organ transplantation possible.
• Pioneered a protocol to infuse kidney transplant recipients with blood stem cells from their donor years after transplantation, thereby minimizing the need for anti-rejection medication.
• Led the pivotal studies resulting in methods to keep hearts and lungs alive outside the human body before transplantation. These FDA-approved platforms are now in wide use.
• Pioneered the surgical technique and performed the world’s first bladder transplant.

Additional Research Breakthroughs and Milestones

• Aneurysm: Invented device that stops deadly bleeding resulting from a brain aneurysm.
• Gene therapy: Developed treatment that effectively cures bubble baby disease.
• AIDS: Reported and described the first cases.
• Nobel Prize: Earned 1998 Nobel Prize in Physiology or Medicine for research demonstrating signaling properties of nitric oxide, making possible treatments for impotence and heart disease.
• California Institute for Immunology and Immunotherapy: Poised to be the leader in translating research into life-changing clinical care.
