let's suppose a hospital may have considered a patient to be a substance abuser. If the patient disagrees with this, but is not made aware the hospital has determined this and signs consent for the hospital to share and receive their medical records, can this be detrimental to said patient allowing employers to access medical records even if patient disagrees with the diagnosis? This was not based on drug testing, can the patient take an independent drug test to refute the claim shortly after consent? Can consent be withdrawn, and if so, would it make a difference or is the damage done? I believe HIPPA has little power to protect confidentiality again once consent has been given, even if withdrawn afterward, correct? Would this affect patient getting accepted into college as well?
