Several patients at an Oklahoma hospital contracted hepatitis C after a nurse reused hypodermic needles. James C. Hill, a nurse-anesthetist at Norman Regional Hospital outside of Oklahoma City, admitted to reusing needles on hundreds of patients from December 2001 through August 19 of this year. Six patients have contracted hepatitis and over 300 more are undergoing tests for HIV, hepatitis C and B. Investigators have yet to determine why Hill, who has since been removed from his position, reused the needles. A lawsuit was filed Wednesday by a patient who received injections at the hospital.
