Almost all hospitals already collect the necessary data. This data is collected on site but isn't shared among hospitals, regions or provinces.
The challenge is to collaborate and find a computerized way to share data between hospitals. This will require willingness, discussion and resolution of patient data security issues. Patient data is, in principle, personal data, and patients must first be allowed to share and discuss it.
So the problem isn't so much that the data isn't collected, but rather that it remains local and isn't discussed between regions.
