Background and Goal: 
While survival from out of hospital cardiac arrest (OOHCA) has been improving and is near 50% in our institution [1], neurological outcomes of the survivors are less known. 
This study aims to:
- determine the level of dependency and neurological deficit of the survivors of OOHCA on discharge from Cardiothoracic Intensive Care (CTICU)
- determine the neurological outcome of the survivors at the point of hospital discharge

Materials and Methods: 
The retrospective cohort investigation was conducted at St. George's University of London Hospital, which is designated heart attack centre. It comprised of patients admitted to CTICU between March 2014 and February 2016, after suffering an OOHCA. The demographic data and the information on level and change of dependency was collected from the CTICU “ward-watcher” database. The dependency scale is: 
A and B -able to live without/with minor assistance respectively;
C and D - requiring major/total assistance. 
Cerebral Performance Categories (CPC):
1-2 Good/Moderate
3-4 Severe Disabilty/Coma
5 died

Results and Discussion: 
Of survivors 34/94 (36.2%) showed no change in dependency. 75/94 (79.8%) had dependency rating of A or B. On discharge from the hospital, 41/94 (43.6%) patients scored CPC 1, 17/94 (18.1%) CPC 2, 7/94 (7.4%) CPC 3 and 1/94 (1.1%) CPC 4. 28/94 (29.8%) had insufficient data to score. Analysis shows that 83% of patients who survive are discharged with a CPC 1-2. Patients were discharged to one of seven medical or surgical wards. 78/94 patients (83.0%) were discharged home.

Conclusions: 
Patients who survive an OOHCA are discharged from CTICU with low level of dependency and low neurological deficit.
Over 60% of patients who survived demonstrated CPC 1-2 suggesting good potential to return to an independent and professional life.
To determine whether this potential is realised a follow up at 6 and 12 months is planned.
