They work closely together. Your primary care physician can give your hospitalist information about your past health, and the two can discuss any significant findings or events. When you are admitted and discharged, your hospitalist sends detailed reports of findings and treatment plans to your primary care physician. Though your hospitalist oversees your care while you are at St. Luke's, your primary care physician is welcome to check on you at any time during your stay. When you are discharged, you return to the care of your primary care physician.
