Post-ICU is a digital health solution designed to optimize post-Intensive Care Unit (ICU) care through a secure digital diary. Targeted at hospitals, healthcare professionals, and patients, the platform facilitates communication between ICU staff, patients, and families during and after critical illness. By enabling collaborative journaling and photo sharing, it aims to alleviate Post-Intensive Care Syndrome (PICS) and PTSD, improve patient recovery, and reduce ICU readmissions. The solution reduces administrative burdens for staff while enhancing patient satisfaction and family engagement in the care journey.
