SNAP-2 (EpiCCS): Home

SNAP-2 Vector

The 2nd Sprint National Anaesthesia Project: Epidemiology of Critical Care provision after Surgery (SNAP-2: EpiCCS) is managed by the NIAA Health Services Research Centre in conjunction with the UCL/UCLH Surgical Outcomes Research Centre (SOuRCe).

SNAP-2: EpiCCS will describe the epidemiology of perioperative risk and outcome, and critical care referral and admission after inpatient surgery in the UK. It also aims to examine whether planned postoperative critical care admission is effective as an intervention to reduce postoperative morbidity.
