The global trigger tool (GTT) is a case note review tool that enables you to understand the main causes of harm in your hospital.

Regular use of the global trigger tool gives your organisation a rate of harm. This then allows you to establish whether as an organisation you are improving, getting safer and becoming more reliable.

These are the previous versions of the GTTs:
