In the US nobody waits three months for a simple gall bladder ablation. What's crazy is you think that's normal. She has 'timely' scans because they are made months in advance.
And the scans are not scheduled months in advance. We complained that we were only informed of the date and time of the next scan a few days before it... The explanation was that they have a must not be done before and a must be done after dates but the actual scheduling is done just in time so urgent case are prioritized before routine care.
