John, I respectfully disagree.
The article you provided, including the example patient, seems to relate to patients with difficult clinical problems, personality disorders, noncompliance. We likely all struggle with these patients but continue to see them.
The posts above describe:
-- "new patient yelling at my staff that we don't need his social security number and that he was here to interview me",
-- a patient asked to pay who stated "so what you and your billing partner need to paint the walls or need to go buy some food or something that you are coming after me for money now"
-- patients who refuse to provide their SSN
-- "a patient who became angry because we asked him to pay his 90 day+ bill (under $20) before he was seen"
-- "patients whose parents refuse vaccinations"
-- "several patients who were shockingly rude to the front office but always polite to me"
-- "a patient who hasn't paid his wife's portion of co-insurance for a walking boot"
-- and I made reference to litigious patients
Have these now become personality disorders?
In the interest of accuracy, I should have used the term "deadbeats". And in the case of parents that refuse to immunize
"potential defendants in a personal injury tort". IMHO many, if not most persons described in the posts above just don't have respect for their fellow man, even someone trying to help them.
