The risk she was worried about was that the last few patients needed more time and potentially urgent care. They are going to have to find another service or not be seen at all. Urgent care or out of hours which might delay treatment. And that could cause harm. This is known risk she was trying to avoid. By effectively hiding behind a computer and not doing what she is professionally obliged to do.
yes she is a mother with a child. But the patient she ducked out of seeing could have been a mother with a sick child.
again if every HCP closes their doors early the demand goes elsewhere. Probably A&E putting those services under pressure and the staff there under strain. Which adds risk to whole system.
Even if the mother with the sick child walked through the clinic door on her last second of work she was professionally obliged to see them. Which is why she should not have voluntarily taken the shift.
I’m sure the calls she recorded as f2f were for low risk benign consultations. Nonetheless she was risking patient harm.
