critical realism as the natural ontological attitude of physicians?

A thought I had when reading this description of medical decision making in The New Ruthless Economy loc 1842. Medical diagnosis is a form of causal reasoning, alive to its own provisionality and fallibility, seeking to identify real mechanisms which explain events that have manifested empirically:

Physicians constantly have to make decisions based on incomplete or ambiguous evidence, decisions they must be ready to reverse in the light of the patient’s changing condition, and these decisions cannot be confined within the rigid straightjacket of process.
