The AMB-BC is the ambulatory care nursing credential from the American Nurses Credentialing Center — the certification for nurses working with patients who are not admitted.
Eligibility
- A current, active registered nurse licence.
- Two years of full-time practice as a registered nurse.
- A minimum of 2,000 clinical practice hours in ambulatory care nursing within the last three years.
- 30 hours of continuing education in ambulatory care nursing within the same period.
Term: five years. The examination is 150 questions, 125 of them scored, over three hours, and can be taken year-round within a 120-day window.
Why it matters more than the setting's profile suggests
Ambulatory care is where nursing is growing. About 19 percent of registered nurses now work in ambulatory healthcare services, and the share of nurses whose main job is in a hospital has been falling.
It is also the least measured part of the profession. There is no ratio regulation anywhere, almost no staffing research equivalent to the inpatient literature, and clinics are staffed to appointment slots — which counts the visits and ignores results management, refill authorization, prior authorization, care coordination, and patient messaging.
In a setting with no external standards, a certification is one of the few available statements that ambulatory nursing is a distinct practice with its own knowledge base rather than hospital nursing done somewhere quieter. See ambulatory care nursing.
Telephone triage is the high-risk part
The specialty's highest-liability activity is deciding, from speech alone, whether a caller needs an ambulance, an appointment today, an appointment next week, or advice — with no examination and often no chart.
The professional association for the specialty maintains a separate scope and standards document for telehealth nursing, now in a seventh edition, defining the practice as the delivery, management, and coordination of nursing care through telecommunications technology. Nurses doing substantial telephone or virtual triage should read it alongside preparing for the examination.
One practical point that catches people out: where the nurse and the caller are in different states, the nurse generally needs licensure recognized in the caller's state. See nurse licensure compact.
Who should take it
Nurses in clinics, physician offices, hospital outpatient departments, specialty practices, infusion centres, student and employee health, and telephone or virtual services.
It is a common credential for nurses who have left shift work for clinic hours and want their new setting to read as a specialty rather than a step down. See leaving the bedside.
