Drug-resistant pathogens are a growing threat to people, particularly in health-care settings. Each year approximately 2 million patients in the United States (US) are infected by nosocomial microorganisms; of these, approximately 9000 die as a result of their infection. More than 70% of the bacteria that cause hospital-acquired infections are resistant to at least one of the drugs most commonly used to treat them and this tendency is increasing. One major source of nosocomial infections are medical devices commonly used in hospitals and health care. Recent reports of strains resistant to vancomycin, which is deemed to be the drug of “last resort” when treatments with other antibiotics have failed, emphasise the need for antimicrobial-equipped medical devices. The demands on those new devices are complex ( ). The product should display broad antimicrobial activity against various microorganisms without affecting patients’ health. In addition, the antimicrobial additive should not interfere with physiochemical and mechanical properties of the treated material and must be applicable to existing formulations and manufacturing processes. Furthermore and most importantly, the integration of new antimicrobial properties in products must ultimately be economical. Today, a variety of antimicrobial active additives is available on the market. gives an overview of the major antimicrobial compounds used as additives for materials for medical devices. Although antimicrobial products claim higher security, reduced rates of infections and better performance, the antimicrobial efficiency of the product is not apparently visible to the user.
