There are certain specialties/parts of the country where suits are more routine in clinic. Surgical oncology at our university hospital wears suits de rigeur. Residents (ie me) can wear suit or standard biz attire (shirt/tie/slacks/leather shoes) and the long white coat.
That said I 100% of the time prefer to wear scrubs. Sometimes in surgery clinic you are changing wound vacs/pulling drains/etc and I don't especially want to be wearing nice clothes when I do that. Probably the reason the attendings wear suits and not the residents...
Sorry you had a bad experience. That noise is unfortunately life in the hospital. Alarms from bed alarms, tele monitor, IV pumps, etc are a constant background noise. Unfortunately those alarms serve a purpose, but there is a reason that "alarm fatigue" is a term.
Depending on why you were in the hospital, asking about chest pain might be perfectly reasonable. We have to ask. I ask people that question all the time even when I am 99% certain I know what their problem is and don't expect them to have chest pain at all.
you would be surprised how many people have chest pain with an associated acute coronary syndrome (aka heart attack or something on the same spectrum) and don't think twice about it.
When it happens outside the hospital, it's a tragi-comedy, when it happens inside the hospital, it's lawsuit material. We make no assumptions about common sense with patients. It's not common.
edit: to illustrate, when meeting patient for first time, I always ask "what medical problems do you have." Then I ask "Do you see a doctor for any reason on a regular basis? take medications every day?" then " No diabetes? high blood pressure? ever have a heart attack? stroke?"
Basically every day I will get the answer "No" to the first question and then with the rest of the questions, something like "Oh well I take a pill for my blood pressure, and also a water pill, now that you mention it I did have 2 stents placed in 2013 and oh yeah a doctor once told me I have heart failure I guess"
