The issue here is knowing your place and knowing your role, because at the end of the day, it comes down to responsibility, accountability, and liability. What you consider to be excessive and unnecessary may be important to others; and what you consider to be important may be nothing to someone else. It all depends on your perspective. The problem in medical training is that there's an element that the doctor doesn't know what he/she doesn't know. That's why we create so many processes and protocols and systems, and tier out your responsibilities that increase as you progress. I think you'll understand this as you progress. Some days, there's enough pieces of evidence that allows you to laser in on the patient's problems like textbook, but after a while, you'll realize that textbook doesn't always happen. There may be enough variations that confuse the clinical picture and although you can probably make a good call, you may choose to hedge in this particular patient case because there is sufficient uncertainty and unpredictability. Someone will call you out on your OCD and unnecessary work, be it a peer, a specialist, the patient, their family, or an insurance company.
But this is the life we choose to lead, and you have to recognize that even though we are doctors, we are also human and what makes medicine such a rewarding field is that no one at no time knows everything down to 100% certainty. Science and medicine advance and we are always learning new things. So, just because someone sees the world in a different way doesn't make them a slave driver. It may be a difference in the facts, but it may also be a difference of opinions. Keep an open mind, and maybe you'll learn something.
Just remember at the end of the day a decision has to be made. You may not be the ultimate decision maker right now, but at some point you will. And at that point, you may find it as liberating to take action unencumbered on one hand but equally burdensome on the other to bear the weight of such awesome responsibility.
