P110?External ventricular drain-related infections: a single centre study

摘要

To quantify the External Ventricular Drain-related infection (ERI) rate in a one year period at Cork University Hospital, and to identify any risk factors for infection.A retrospective audit of all External Ventricular Drains (EVDs) inserted in a one year period.All patients who had an EVD inserted between February 2017 and February 2018.Patients were identified from operating theatre logbooks. All relevant data was obtained from a retrospective review of medical and operative records. ERI was defined as evidence of positive CSF culture.41 EVDs were inserted in a total of 30 patients during the study period. The average age was 52.9 years. 46.6% of patients were female. The average length of EVD insertion was 8.85 days. The most common reason for EVD insertion was subarachnoid haemorrhage (31.7%) followed by supratentorial tumour (24.4%). 78% of EVDs were antibiotic-impregnated. Average EVD sampling rate was 0.7. ERI rate was 1/41 (2.4%). The infection occurred in a patient who had an EVD inserted for haemorrhage secondary to an AVM which had remained The ERI rate in our patient cohort was 2.4%. We recommend using a strict EVD sampling protocol to minimise manipulation of EVDs and where possible to limit the length of time an EVD remains.
