Concierge Medicine (CM) is a concept where patients pay an annual fee, similar to a retainer fee that attorneys receive, that allows the payee constant access to their personal physician.  The fee can range from $1000 to $15000 per year, but averages $1500-1800 per patient.  For this fee the patient receives 24/7 access to their personal physician, priority scheduling, and maybe discounts on routine and preventative screenings.  It sounds like a good deal for the patient, but what are the advantages and disadvantages for the doctor?
