Resistant microorganisms are public health problems because they affect the treatment of infectious diseases and the survival of patients. Neurosurgical procedures with placement of intracranial pressure monitoring and external ventricular drainage devices are related to increased morbidity and mortality. In Brazil, there are several multicenter studies demonstrating the prevalence and types of resistant microorganisms, however, there is a lack of data related to central nervous system infections associated with invasive devices, which can have a direct impact on prevention and treatment policies.

Neurosurgical procedures with placement of devices are related to increased morbidity and mortality. A study shows that the incidence of device-related central nervous system infection can reach 27%. A meta-analysis published in 2015, which included 35 studies, showed an incidence of 11.4 per 1000 catheters-day.

This is a prospective cohort study, including adult patients, in the ICUs of hospitals participating in the IMPACTO MR Platform, who have a catheter device for monitoring intracranial pressure or external ventricular shunt, with infection densities and microbiological profile being evaluated; risk factors; clinical management; costs involved and short- and long-term clinical outcomes

Inclusion Criteria:

• All patients over 18 years of age admitted to the ICU in the selected hospitals during the study period, using intracranial pressure monitoring catheters and/or external ventricular shunt.

Exclusion Criteria:

• Diagnosis of brain death.

Adults admitted to Intensive Care Units.
