If capturing some patient identifiable information is unavoidable, it is possible to draw over the screenshot. When viewing the captured image in Snipping tool, holding the left mouse button down makes it possible to 'draw' over any patient identifiable information. There are tool options at the bottom to change the colour or thickness of the line. See example below where Mickey Mouse's name has been covered by red lines. To minimise the amount of patient name showing, position the mouse over the alert icon (eg: red circle / yellow triangle) as the tooltip aligns itself directly above the mouse position.
