Given that ventilator-associated pneumonia (VAP) causes substantial morbidity, mortality and costs, prevention of this infectious process is a major challenge. ⋯ Several preventive measures have been shown to reduce the rate of VAP but many less have demonstrated an impact on patient outcomes (noninvasive positive pressure ventilation, sedation and weaning protocols, selective digestive and oral decontamination and endotracheal tube with drainage of subglottic secretions). Patients at risk must be approached with a bundle of preventive measures. Beyond the theoretical frame, a great deal of attention must be given to the factors that might improve adherence to those preventive measures. Future clinical trials testing new strategies in preventing VAP should have patient outcomes (i.e. a reduction in the length under mechanical ventilation, in the duration of stay in healthcare settings or in antibiotic consumption) as primary end-points rather than VAP rates.

Catheter-associated urinary tract infection (CAUTI) is the commonest nosocomial infection worldwide. Here we review the recent advances in the prevention of CAUTI. ⋯ Numerous strategies have been developed to reduce the incidence of CAUTI but few have proven effective. Reducing the inappropriate use of catheters and development of novel technologies targeted against these increasingly multidrug-resistant pathogens may be useful in the prevention of CAUTI in our vulnerable patients.
