National External Ventricular Drainage Audit

National External Ventricular Drainage Audit

Trainee Leads: Aimun Jamjoom and Aminul Ahmed

Main outcome: EVD infection rate
Length of audit: 3 months


We aim to establish the demographics, current practice patterns, and infection rates of External Ventricular Drain (EVD) insertion across the UK and Ireland.


We propose a prospective, multi-centre audit of EVD management in the United Kingdom (UK) and Ireland. The audit will be run under the auspices of the British Neurosurgical Trainee Research Collaborative (BNTRC), Society of British Neurological Surgeons (SBNS), the British Neurotrauma Group (BNG), the UK Shunt Registry, the Reduction of Shunt- and EVD-related infections collaborative group (RoSERI collaborative group) and the UK Neurosurgical Research Network.



All neurosurgical units in the UK and Ireland will be invited to enroll and data will be collected over a 3-month period. The audit aims to include patients of all ages who have an EVD inserted in participating units. Our proposed outcome measures include: (1) EVD-related infection (ERI) rates; (2) duration of EVD placement; (3) need for a ventriculoperitoneal (VP) shunt; (4) length of stay in neurosurgical unit; (5) GCS on discharge; (6) number of EVD replacements and (7) patient mortality. Follow-up for ERI and patient mortality will be 30 days from EVD insertion while follow-up for need for VP shunt will be 90 days from insertion. The ERI audit standard has been set from the literature at below 15%.



This audit will determine contemporary EVD practice and will establish national benchmarks. Alongside this, it aims to identify standards that may be associated with improved outcomes. This will guide future research under the British Neurosurgical Trainee Research Collaborative and the UK Neurosurgical Research Network.
