Saint Alphonsus Health System

Trauma & Emergency

Saint Alphonsus Regional Medical Center in Boise is nationally verified by the American College Surgeons as a Level II Trauma Center. Saint Alphonsus Medical Centers in Ontario and Baker City are Level IV Trauma Centers. This achievement recognizes our dedication to providing the highest quality, most optimal care for all injured patients.

Our trauma network reaches from southern Idaho, eastern Oregon and northern Nevada and has brought a level of medical responsiveness that is unmatched throughout the region. Not only do we provide the hospital resources necessary for care, but we focus on the needs of all injured patients from pre-hospital and on-scene care provided by first responders all the way through a patient’s rehabilitation and successful return back to their community.

Our trauma network is supported by our Emergency Departments in Boise, Eagle, Nampa, Ontario and Baker City.  Staffed by board-certified emergency physicians and certified emergency nurses, our Emergency Departments are all integrated and offer the highest standards of care for chest pain, stroke, orthopedic and general emergency services. 

Making a Critical Difference for Seniors

In response to the needs of an aging population Saint Alphonsus Health System is the first in Idaho and Oregon to open Senior ER’s™ within all our current emergency departments

Saint Alphonsus Senior ER’sTM address the special medical needs, preferences and physical comforts of older adults.  Beyond the typical ER visit, where staff focus on treating the medical issue at hand, the Senior ER goes deeper, assessing and addressing root causes for each visit.

To create the Saint Alphonsus Senior ER, we implemented fundamental changes in our culture, physical environment and operations. Each Senior ER is run by a specially trained care team focused on providing a better, gentler, more patient-centered experience that produces better patient outcomes.

  • Emergency Nurses have completed indepth courses on Geriatric Emergency Nursing Education 
  • Emergency physicians have specialized knowledge in the care of seniors
  • Pharmacists may review medications that could pose a problem or may have contributed to the patient’s ER visit
  • Licensed social workers or case managers may be available to discuss care options and screenings with both the patient and the caregiver
  • Facility modifications have been made to address the safety, comfort and communication for seniors, and may include:
    • quieter setting for care
    • pressure reducing mattresses
    • hearing and vision aids
    • large print
    • appropriate flooring and lighting
