INTRODUCTION:
Critical Burn patients care requires a highly specialized and complex healthcare service (1).
Even though some efforts in Spain has been done to report incidence and outcome of this patients (2,3) these data in our environment is unknown.

OBJECTIVE
To describe clinical characteristics and outcome of critical burn injury in adults admitted to the burn intensive care unit (BICU) at Vall d’ Hebron University Hospital at Barcelona, Spain between February 2013 until January 2017.

METHODS
Retrospective monocentric analysis of adult patients admitted to BICU during the study period.
Date, gender, age, cause of admission, burn extension, ICU length of stay (LOS), Mechanical ventilation (MVLOS) and mortality were recorded. Data is presented as absolute numbers and percentage or median and interquartile range as required.

RESULTS
One-hundred forty-eight patients were admitted, 120 (81%) were male. Median age was 47.5 years (IQR25-75: 33-60.7). Principal cause of admission was burned by flame in 72 patients (48.6%), followed by deflagration in 56 (37.8%), electrocution 8 (5.4%), hot liquids 7 (4.7%), chemical cause 3 (2%). Median total burn body surface (TBBS) was 22% (IQR25-75: 15.2-35.7). 44 patients (29.7%) had smoke inhalation  injury. ICULOS median was 19 days (IQR25-75: 8-33.5) and MVLOS median 13 days (IQR25-75: 3-27). Patients were divided according
to distribution in three groups: less than 15%TBBS, between 15.1% TBBS and 35.7%TBBS, and over 35.7%TBBS. 26 patients (17.6%) were dead globally. Relation between TBBS and mortality was higher in the over35.7%TBBS group: 17patients (65,4% p=<0,001 RR 9.63 IC95%: 3.76-24.74)).

DISCUSSION/ CONCLUSION
Patients admitted to this BICU during the study period were predominantly middle age men burned by flame with a TBBS between 15.2 and 35.7%TBBS. High mortality rate is observed globally specially in those with a TBBS over 35.7% of TBBS.
