Background: Ultraviolet lighting is an alternative to laminar airflow in the operating room that may be as effective for lowering the number of environmental bacteria and possibly lowering infection rates by killing the bacteria rather than simply reducing the number at the operative site. The purpose of the present study was to compare the infection rates following joint replacement procedures performed by one orthopaedic surgeon with and without the use of ultraviolet lighting.
Methods: From July 1986 to July 2005, one surgeon performed 5,980 total joint
replacements at one facility. In September 1991, ultraviolet lighting was
installed in the operating rooms. All procedures that were performed before
the installation of the ultraviolet lighting utilized horizontal laminar
airflow, whereas all procedures that were performed after that date utilized
ultraviolet lighting without laminar airflow. Factors associated with the rate
of infection were analyzed.
