+
+<!--toc:end-->
+
+## Intro
+
+- History: ![history](./assets/5-smart-health-history.webp)
+- Patient centric
+- Precision medicine
+- Atrial digital twins
+
+## Reasons
+
+- Current problems:
+    - Global Health Disparities
+    - Unequal shortage of healthcare workers
+    - Increasing rate of burnout in healthcare
+    - Mental health
+    - Sustainable Development Goal 3
+- What smart healthcare can help
+    - Remote doctor consult
+    - Reduce un-necessary hospital visits
+    - Democratize healthcare access
+- Remote emergency
+    - 5G powered emergency channel give doctor real time view
+    - Real time access of vital signs like ECG, ultrasound image, and blood
+      pressure
+    - Access to medical history
+    - Doctors guide paramedics in ambulance
+- Drug discovery
+    - Cost saving and agility methods
+    - All fancy words including (ML, DL, ANN)
+- Offset a shortage of specialists
+    - AI can help in aiding diagnosis
+- Before smart hospitals
+    - Data presented is overwhelming
+        - hindering the ability of using it effectively
+    - People trip and die in hospitals
+    - Too much administration work
+    - Shortage of qualified staff
+    - Spending wasted in managing assets
+    - Nurses waste time in searching for medical equipment
+- Benefits of smart hospitals
+    - Save money on asset searching
+    - Reminder
+    - Home-based health monitoring reduces re-admission
+    - Eliminate emergency
+    - Warning of deterioration
+
+## Implementation
+
+- EMR: Electronic medical records
+    - Diagnosis, Image Data, Unstructured text data, Medications, Procedures,
+      Lab tests
+    - Data is challenging to use: high dimensionality, sparse, noisy, irregular,
+      biased
+- IoMT: lots of data, lots of money going in
+- Healthcare technology: Better quality of life, with less money required
