The CRRN is the rehabilitation nursing credential, awarded by the Rehabilitation Nursing Certification Board.
Eligibility
A current, unrestricted registered nurse licence in the United States, its territories, or Canada, plus one of the following within the five years before applying:
- Two years of practice in rehabilitation nursing as a registered nurse; or
- One year of practice in rehabilitation nursing plus one year of advanced study in nursing beyond the baccalaureate degree.
Applications also require the contact details of two professional colleagues who can verify the rehabilitation nursing experience — one a supervisor or another certified rehabilitation nurse, the second another healthcare colleague.
That verification requirement is unusual in nursing certification. It exists because rehabilitation practice is not always identifiable from a job title: a nurse on a skilled nursing unit may be doing substantial rehabilitation nursing, and a nurse whose title says rehabilitation may not be.
What the examination covers
The specialty's distinctive content rather than general medical-surgical nursing:
- Bowel and bladder programmes, particularly after spinal cord injury.
- Skin protection in patients with impaired sensation and mobility.
- Spasticity, contracture, and pain management that keeps a patient able to participate in therapy.
- Cognitive and behavioural management after brain injury.
- Autonomic dysreflexia recognition and treatment.
- Family training and discharge preparation.
The organizing principle is the one that defines the specialty: doing things for the patient is the error, and the nursing job is to carry therapy gains into the other twenty-one hours of the day. See rehabilitation nursing.
Where it is used
Inpatient rehabilitation facilities and units, where admission is tightly governed by federal coverage criteria — multiple therapy disciplines, close physician supervision, and the ability to participate in an intensive programme, generally 15 hours of therapy a week.
Skilled nursing and sub-acute rehabilitation, for patients who cannot tolerate that intensity. See long-term and post-acute care nursing.
Long-term acute care hospitals, and home-based rehabilitation. See home health nursing.
What it is worth
Rehabilitation is a specialty that retains people well, largely because nurses see the whole arc — admitting a patient who cannot sit up and discharging them walking. Certification is the standard evidence of established practice in it, and inpatient rehabilitation facilities under coverage scrutiny value a certified workforce as part of demonstrating that their nursing is genuinely rehabilitative rather than custodial.
Nurses moving in from neuroscience or orthopaedics find much of the clinical content familiar and the philosophy unfamiliar, which is the part the credential actually tests. See neuroscience nursing and orthopaedic nursing.
