The ICU Diary app, also available on the web, allows clinical staff and relatives to easily create a secure and legible diary for an ICU patient.

Documenting a patient’s time in ICU helps them and their relatives to 'make sense' of what has happened.The majority of patients have little or no memory of their time in ICU. The diary can help them to piece together events to better understand what happened and how unwell they have been. Keeping a diary helps patients to sort troubling memories from reality. This improves mental health and aids physical recovery and may also reduce the incidence of post-traumatic stress disorder (PTSD).

The diary can be printed and presented to the patient at an appropriate time in their recovery. The printed version includes photos, a glossary of terms and contact information.
