just a note not everyone lives in the same state let alone same country so check your local electrical codes.
Your probably going to want to be in code as your insurance company will definitely hang you out to dry if you have a fire and they find non-compliant outlets in your house.
Then there is the why bother if your house is only 4 yours old. I don't imagine the current outlets have lost their grip already. main difference to the hospital outlets if higher grip force on the plug, more robust, built to higher standards. Not much difference in the conductors etc. We don't generally plug and unplug our audio equipment multiple times a day so I don't see the need for them. your value may differ though.
