(Reuters Health) - Helping people who were recently released from a hospital understand how to care for themselves and informing their primary care doctors about their stay may reduce their risk of being admitted back into the hospital, says a new study. Researchers found that implementing a statewide transitional care program for North Carolinians on Medicaid - the state and federal insurance for the poor - was linked to a 20 percent reduction in patients' risk of going back to the hospital during the next year.
