With a Sudden Drop in Donors, Organ Shortage Worsens
Hospital officials says that number of vital organs being donated in New York area has fallen so precipitously in recent weeks that transplant programs across region have virtually ground to a halt; shortage of livers, hearts, kidneys and other organs has been a growing national problem in recent years, in part because of falling homicide rates and improved auto safety at same time that demand for organs has risen; but officials say that since beginning of year, supply in New York has taken a severe--and unexplained--downward turn; since start of year, there have been just 9 organs donated in New York region; last year at this time, there were 22 donors; photo (M)
