Description
What is Treatment of Disease, Disorder and Injury and Why Add TDDI CQC Registration?
Treatment of Disease, Disorder and Injury (TDDI) is one of the regulated activities under the Care Quality Commission (CQC). If your service involves providing medical care or interventions—such as wound care, administering medication, or managing chronic conditions—you’ll likely need to be registered for TDDI. Including this regulated activity as part of your TDDI CQC registration allows you to deliver a broader and more advanced range of healthcare services.
What Does Treatment of Disease, Disorder and Injury Cover?
TDDI includes the diagnosis, care, or treatment of physical or mental health conditions by a qualified health professional. This could involve:
-
Administering prescribed medication
-
Managing long-term conditions (e.g., diabetes, asthma)
-
Providing nursing care or clinical assessments
-
Treating minor injuries or infections
To carry out TDDI, you must have the right clinical governance, skilled staff (such as nurses), and policies in place to ensure safe, effective care.
