MUI Reporting

A Major Unusual Incident (MUI) means the alleged, suspected, or actual occurrence of an incident when there is reason to believe that 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. 

If you are concerned that a MUI has occurred, contact the SSA or the County Board Office at 740.477.3353 Monday – Friday, 8 am to 4:30 pm. If you are reporting outside normal business hours, call  740.497.2887. If you are sending in a report after speaking to the MUI director or SSA, send it to the SSA by the next business day at 3:00 p.m.


The Ohio Department of Developmental Disabilities has a Health and Safety Toolkit on its website.  The Toolkit includes information specifically grouped for families, providers, and county boards of developmental disabilities, and features helpful forms and fact sheets.

Examples of items within the Toolkit include:

> Quick access to Health and Safety Alerts

> MUI Reporting Information

> MUI Rules Handbook

> MUI Rules “At A Glance”

> Related Rules

The Department plans to update and augment the Toolkit with new materials as they become available.
