Paper Abstract

Our experience with Quality Control Programs in many x-ray departments shows that the reject rate can frequently be reduced about 45% through proper controls. A Reject Analysis establishes the current reject rate and its associated film cost. Based on the reject analysis, appropriate corrective programs are undertaken. Typical corrective programs are processor monitoring and maintenance, screen/cassette program, inventory control and technique consultation. Six months to one year after the Reject Analysis, a follow-up Reject Analysis measures the effect of the Quality Control Program. Data compiled from many x-ray departments indicate an average reject rate of 13%. The chest exam usually accounts for the most repeats. Incorrect density and poor positioning are the major reasons for repeated exams. The Quality Control Program usually reduces the reject rate to about 7%, a 45% reduction. If the annual film cost is $150,000, the savings from this reduction can be as much as $9,000 in film alone. Other costs such as chemicals and equipment are also reduced.
