The whole point of the article is that many doctors have had to step into roles or acuity levels that were not every day material for them and not what they signed up for. A trauma surgeon expecting gunshot wounds could well find it much more challenging to be working as an ICU physician, where you can't detach yourself as easily, and where you can't use your most-practiced skills, and where you can't know by the end of the procedure whether the patient's odds are good. They specifically didn't sign up for that. It's easy to say "don't get personally invested" but even if you're not getting attached to particular patients, it's demoralizing to go from an environment where you see a range of outcomes (including some bad ones) to one where you're constantly surrounded by patients near death with little chance for improvement and where your skills don't necessarily seem to matter. That's not about being invested.
