There may be occasions when you see an alert on a patient home screen but you don't know why it is there.
If you click on 'More' to the right of the alert and select 'Why is this alert on this patient?'
You can get to the same options by right clicking on the alert symbols under the patient demographics box.
You should then see a list of ticks something like this. Click on the small white triangles to expand each layer.
As soon as you find a red cross move on to another row and eventually you will find the reason. As you can see in this example the patient is Diabetic and that is why the 'Consider influenza Vaccination alert is on the home screen for this patient.
It is basically the same process for all alerts.
