General Information

Memorial Hermann's Katy ER stands ready to meet the needs of critically ill or injured patients throughout Katy and West Houston – adults and children. When emergencies arise, Memorial Hermann Katy’s Emergency Room offers services 24/7. Our Chest Pain Center is fully accredited to provide fast, effective treatment for heart attack patients, and separate minor care and acute trauma areas ensure that efficient care is available when you need it.

Memorial Hermann Katy ER - A Level IV Trauma Center

A Level IV trauma center provides initial evaluation, stabilization and transfer to a higher level of care. Our Level IV facilities also offer essential diagnostic capabilities and provide surgery and critical care services related to trauma care. When the patient arrives at the Emergency Room, a nurse trained in trauma care is immediately available to provide critical care with physicians available for consultation as well. If the situation demands, transfer agreements and protocols allow patients to be transferred quickly to a higher level of care within Memorial Hermann’s network of trauma centers.

Having an integrated and comprehensive network of trauma centers allows Memorial Hermann staff throughout the city to work in unison, no matter the location or needs of a patient. At any Memorial Hermann Emergency Room, a patient benefits from the knowledge of a large network of physicians and nurses trained in emergency medicine as well as the years of experience Memorial Hermann has accumulated as Houston’s emergency care leader.

If the need arises, patients are seamlessly transferred to the appropriate facility by ambulance or by Memorial Hermann’s own Life Flight®.
