Major Unusual Incident

A major unusual incident (O.A.C.5123:2-17-02) is defined as any alleged, suspected, or actual occurrence of an incident that adversely affects the health and safety of an individual. There are nineteen types of incidents defined in the rule that are considered major unusual incidents (MUIs). All of the incidents require that immediate action is taken to protect individuals from further harm, that an investigation is conducted to determine the cause of the incident and contributing factors, and that a prevention plan is developed to reduce the likelihood of future occurrences.

MUIs are reported to the local County Board of DD, which then reports the information to the DODD. County Boards of DD are responsible for immediate action, investigations, and prevention planning for each incident.

The DODD Major Unusual Incident and Registry Unit reviews all initial MUIs to ensure immediate actions are in place and appropriate notifications have been made. In addition to this review, the DODD provides technical assistance to providers and counties and routinely conducts assessments of each County Board of DD and Developmental Center’s system for ensuring health and safety. The DODD also conducts separate investigations as outlined in the rule, and manages the Abuser Registry.
