A Major Unusual Incident (MUI) is defined as an alleged, suspected, or actual occurrence of an incident when there is reason to believe the health or welfare of an individual may be adversely affected or an individual may be placed at a likely risk of harm, if such individual is receiving services through the developmental disabilities service delivery system or will be receiving such services as a result of the incident. There are three categories of major unusual incidents that correspond to three administrative investigation procedures delineated in appendix A, appendix B, and appendix C of O.A.C. 5123-17-02. There are nineteen types of incidents defined in the rule that are considered major unusual incidents. Please view the MUI and UI fact sheet for more information.

In the event you suspect a person with a developmental disability is being abused or neglected, please call 9-1-1 immediately, and then call the MUI hotline (740) 605-7746.

Additional information such as the Health & Welfare Tool-Kit and Health and Welfare Alerts can be found on our website under the resources tab and also on the Ohio Department of Developmental Disabilities website.
