Unusual Incidents

An unusual incident, also called a UI, is an event or occurrence involving a person that is not consistent with routine operations, policies, and procedures, or the person's care or service plan, but is not a major unusual incident.

For full definitions of each UI type, read OAC 5123-17-02

Types of Unusual Incidents

Dental Injury

Such as a chipped or loose tooth.


For example, a person stumbles on the last step of a staircase and falls to the floor, but the person is not injured.


Injury that's not a Significant Injury MUI. For example, a person’s hair is pulled.

Medication Error

Medication Error without a likely risk to the person's health and welfare. For example, a person is accidentally given a medication that was not prescribed for them and there was little to no risk to the person.

Overnight Relocation

Overnight relocation due to fire, natural disaster, or a mechanical failure. For example, there is a lightning strike on a home, power will be off for a week for repair, and the residents temporarily move to another house.

Peer-to-Peer Act

Peer-to-Peer Act that is not an MUI. For example, two roommates get into an argument and one picks up an object and throws it at the other, hitting their arm and causing a small scratch.

Program Implementation

Program implementation is the failure to carry out a person-centered plan, when the failure causes minimal or no risk.

For example, a person is left without supervision for 20 minutes, but their plan states that they can not be without supervision for more than 15 minutes. There was no injury and minimal risk to the person’s safety.

Rights Code Violation

Rights Code Violation without a likely risk to the person's health and welfare. For example, a person is told they cannot have a second glass of milk at dinner.

Unapproved Behavioral Support 

Unapproved Behavioral support without a likely risk to the person's health and welfare. For example,  a direct service provider redirects a person who is picking at a sore on their face by briefly placing their hands on top of the person’s hands. The person does not resist.
