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.

Once again this study would not have been possible without the generous effort of many collaborators. The individual collaborators who contributed data to this specific part of SNAP-2 will be appropriately recognised in PubMed, but this may take a little time to upload, so please be patient with us!

SNAP-2 Archiving

We are currently doing data-linking with NHS Digital to obtain the ONS-linked mortality for all the patients who were included in the study. We kindly ask sites to delay the archival until the 1 year anniversary of the data collection: March 27th 2018


SNAP-2 Data Collection Portal CLOSING 31 July 2017

We will be closing out the SNAP-2 study database on Monday 31 July 2017.

We therefore ask all sites to please complete all their follow-ups and upload all their data before this date.

If you have any problems with this please contact us on snap2@rcoa.ac.uk or Tweet us @SNAP2EPICCS.


SNAP-2 running in Australia and New Zealand!

We are delighted to announce that SNAP-2 will be running in Australia from Wednesday 21 - Tuesday 27 June and in New Zealand from Tuesday 5 - Monday 7 September.

In order to have separate sites for the UK, Australia and New Zealand we need to make a slight change to the address of the SNAP2 web tool.

The new address for the UK site will be https:snap2.snapresearch.org.uk/uk.

If you enter the original address of https://snap2.snapresearch.org.uk you will simply be provided with a list of the three SNAP-2 web tools. Clicking on the link for the UK site will take you to the new address.

Any problems or queries please let us know, and good luck to all our colleagues down under!
