Yes, I would agree with this. I used to work in medical complaints and some people are terrible at making clear exactly what their issue is, and also taking on board what a doctor says/not asking for clarification.
People swore blind they/their family member had repeatedly raised exactly what their symptoms were with the doctor, and then when listening to the call records (particularly during covid when there were far fewer in person appts) no mention whatsoever, or at best a one-off during a litany of other symptoms, and never mentioned again.
Either that or they say things like 'I've had a stomach ache for a few days, it comes and goes,' and then when asked for more detail say 'I'm not sure.' Rather than specifying exact place, how long symptoms have been going on for, whether it's getting worse or staying the same, if it coincides with anything else (e.g. after eating/drinking), what 'type' of pain it is, etc.
Equally common were people insistent the doctor had 'never told them,' xyz, when the medical records refer in black and white to repeatedly being told that exact thing.
Of course there are some arrogant/lazy doctors as well, and the example with Jessica is extreme and something should have been picked up - although if they aren't being investigated (not entirely sure how you'd even know that, as investigations should be private) then that's because the family hasn't made a complaint, which is of course entirely their prerogative and not for us to judge.
