I'm not sure how looking at large scale trends and scenarios experienced by thousands/millions is anything but holistic, especially when talking about individual patients with individual specialists dealing with individual . > Holism (from Greek ὅλος holos "all, whole, entire") is the idea that various systems (e.g. physical, biological, social) should be viewed as wholes, not merely as a collection of parts. Of course it would be best if there was a universal language which everyone was proficient in, every patient had unlimited healthcare resources, had a strong understanding of medicine and every doctor was an excellent communicator, was under no personal/professional pressure to deliver specific outcomes, always took all the time a patient needed to understand every aspect of their case and care in the present and into the future and personally consulted with every possible specialist that may be involved with the potential outcomes. Putting aside the strawman, there are significant compromises with the highly personalised approach you suggest (some of which I tried to outline, but have not been responded to), just as there are with national level approaches (which are self evident). I feel that there are applications for both.
