His unit is part of a government initiative called the "Cancer Collaborative," which applies business management principles to cancer care. To see if the 2-week initiative was working, Roberts and his colleagues analysed information on nearly 3,600 GP referrals to King's College Breast Clinic between April 1999 and December 2000. They found that 665 - only 18.5% - were marked as urgent and the remainder non-urgent. Remember, urgent means that a patient must be seen within two weeks.
