A short history of the Foley catheter: from handmade instrument to infection-prevention device.

Although it is one of the most frequently utilized devices in the hospitalized patient, the Foley catheter has often been taken for granted. This lack of attention is unfortunate, as the Foley catheter remains one of the primary sources of hospital-acquired infections, which increase morbidity, mortality, and the financial burden on the healthcare system. Although education on the appropriate techniques, proper use, and early removal of Foley catheters is important, such measures unfortunately result in transient benefits. Current technologic advancements have moved the coating technology to a state where bacterial adhesion and migration can be limited and the frequency of catheter-associated urinary tract infections can be reduced. Future technological advances in the Foley catheter will help provide better care and comfort for the catheterized patient.
