The Nursing and Midwifery Board of Ireland (NMBI) is the statutory regulatory authority for nurses and midwives in Ireland. It is governed by the provisions of the Nurses and Midwives Act 2011 (the 2011 Act).

The commonest reason for a health-related complaint is drug abuse, which may lead to a nurse or midwife being on duty in an unfit state, theft of drugs or prescription pads, or forgery of prescriptions. Alcohol abuse and serious mental health problems are the next most common health problems. Physical health problems are rarely the cause of a complaint.

There are currently over 90,000 nurses and midwives on the Register (over 60,000 are Active and over 30,000 are Inactive). NMBI receives less than 100 complaints each year, meaning that a very small number on the Register are the subject of a complaint.
