NAI, short for ‘non-accidental injury’, refers to any physical harm inflicted upon an individual intentionally, rather than as a result of an accident or natural cause. This term is commonly used in the medical and legal fields to describe injuries that are suspected to be caused by abuse or violence. NAI can include a wide range of injuries, from bruises and cuts to broken bones and internal trauma. It is a serious and concerning issue that requires proper investigation and intervention to protect the well-being of those affected.
