The biennial Dartmouth Atlas of Health Care is out and the findings are as eye-popping this year as they have been in the past.  Among chronically ill patients in the last two years of life: 

• New Jersey patients spent almost three times as many days in the hospital as patients in Utah.
• Patients in Manhattan had 3½ times as many hospital days as patients in Bend, Oregon.
