We foster patient and family participation:

  • Patients and families play an active role in developing a customized treatment plan. Family members are strongly encouraged to participate in the patient’s rehabilitation process.
  • Engagement in therapies and meetings held during hospitalization is essential.
  • Dedication to developing skills necessary to transition safely home is vital.

We encourage independence:

  • We encourage our patients to become as independent as possible, but we are always available to assist when needed. It is important that our clients learn to be self-sufficient when able.
  • Often it is difficult for family members and friends to watch loved ones struggle with various tasks. We ask that family and friends avoid helping the patient with tasks where help may not be necessary.
  • The entire rehabilitation team will be available to instruct family members on the type of help that is most beneficial for the patient's recovery.


The Center for Medicare and Medicaid Services (CMS) requires all Inpatient Rehab Facilities (IRF) to adhere to a specific set of admission requirements. The patient must require and be sufficiently stable to participate in and benefit from at least three hours of therapy/day from at least two different therapies, one of which must be PT or OT. The patient must require supervision by a rehabilitation physician leading an interdisciplinary process that allows the

patient to make measurable improvement in functional status providing for the likelihood of a community discharge. The Acute Rehabilitation Unit at Mission Hospital accepts referrals from physicians, social workers, rehabilitation nurses, case managers, discharge planners, insurance companies, public and private agencies, patients, and their families. Candidates for admission will receive an assessment to determine their appropriateness for the program. Reimbursement is accepted from private insurance and Medicare. A plan for a viable transition back to a community setting is an imperative part of our program. More specific ARU program parameters information and frequently asked questions.
