Clinical Trial Summary
Severe trauma is one of the leading causes of morbidity, mortality, and disability worldwide.
Currently, it is the primary cause of death among individuals under 45 years of age. This
disease, considered a "silent pandemic," exhibits heterogeneous physiopathology and unequal
geographic distribution in terms of the type of injuries. The prognosis of subjects who have
suffered severe trauma is uncertain, especially in patients with traumatic brain injury.
The epidemiology of severe trauma has undergone changes in recent years due to the global
aging of society, resulting in different populations with older ages and more associated
comorbidities. These factors are frequently linked to the use of chronic treatments such as
antiplatelet agents or anticoagulants, which could worsen traumatic hemorrhage-the leading
preventable cause of death following severe trauma. Despite efforts for primary prevention,
such as road safety campaigns and occupational risk prevention, the annual incidence of
severe trauma cases worldwide remains high. Enhancing the management of trauma patients would
significantly influence the final clinical outcomes.
Given the aforementioned, it is of vital importance to understand the local epidemiology of
severe trauma for the development of clinical research. This constitutes an effective tool to
investigate changes in clinical practices, improve prevention strategies, and determine the
global burden of the disease.
The hypothesis of the IcuTrauma Project is to create a territorial Registry of adults with
severe trauma admitted to the ICU to understand the local epidemiology in Tarragona (Spain).
This initiative would facilitate new lines of clinical research aimed at improving outcomes
and the quality of care for trauma patients.
Description:
- Study design: observational, retrospective, one centre (Hospital Universitari Joan
XXIII) in Tarragona, Catalonia, Spain.
- Study period: Seven-years period: Since 01 January 2015 - 31 December 2022 (The registry
will be open and active recruiting after this time point).
- Sample size calculation: Not applicable. The sample size will be equal to the total
number of patients consecutively admitted to the Intensive Care Unit (ICU) due to severe
trauma during the study period.
- Data extraction:
Data will be extracted by twofold:
1. Hand-driven: extracted data from the medical reports by reviewing the clinical history
system performed by the study investigators, who are part of the staff of the ICU
involved in the care of trauma patients. This information was collected into a
large-scale database and, once introduced, the data was checked and verified by two
investigators (and principal investigator).
These manually extracted data included pre-hospital variables (such as the time of the
injury, the mechanism of injury, first vital signs, pre-hospital procedures),
in-hospital information (demographic's, primary survey of trauma in emergency
department-ED, use of Extended Focused Assesment with Sonography in Trauma, complete
laboratory results in ED), description of detailed anatomic injuries (Traumatic Brain
Injury-TBI, thoracic trauma, abdominal trauma, Pelvic trauma, orthopedic injuries),
severity scores (Acute Physiology And Chronic Health Evaluation-APACHE II, Sequential
Organ Failure Assessment-SOFA score, Injury Severity Score-ISS, Abbreviated Injury
Score-AIS, etc), resources during ICU admission (surgeries, transfusions, organ support,
etc), complications (organ failures and nosocomial infections such as
ventilator-associated pneumonia, catheter-related infection, etc), and clinical outcomes
(ICU mortality, cause of death, in-hospital mortality, one-year survival, mechanical
ventilation days, ICU and hospital length of stay, disability at ICU discharge and
destination at discharge.
2. Automatic data: automated data collected with the Electronic Health System (Centricity
Critical Care) provide solid and valid extraction of information. Automatic variables
were checked and validated by the expert and specialized members of the ICU in data
quality assessment and the management of data to ensure that recorded information was
reliable. The accuracy, completeness and representativeness of automatic data was double
checked when entered into the large-scale database for data quality by the principal
investigator and a biotechnologist, who were responsible for the quality assurance plan
that addressed data validation, monitoring and auditing (identifying inconsistencies,
outliers or incorrect ranges for variables entered into the registry). The automated
variables collected (not recorded manually) included demographic data, comorbidities and
previous risk factors, dates (hospital and ICU admission, hospital and ICU discharge),
laboratory tests during the first week of ICU admission, resources consumption during
ICU stay, complications during ICU admission and outcomes.
- Statistical plan: descriptive and analytical statistics using binary logistic
regression (for association), survival analysis with Kaplan Meier analysis and Cox
regression (for clinical outcomes), nonlinear association test such as CHAID
decision analysis and restricted cubic splines, and matching learning analysis (for
cluster or subgroups identification). These analyzes will be carried out using SPSS
v24 and R software. Missing data values of automated variables will be handled
using multiple imputation. Hand-driven data had negligible missing values.
- Variable definitions (all definitions met the ATLS-Advanced Trauma Life Support
criteria):
- Previous anticoagulants or antiplatelet agents: chronic use of aspirin,
clopidogrel, other antiplatelet agents, acenocumarol, warfarin, new
anticoagulants.
- Pre-hospital airway protection: includes supraglottic device, orotracheal
intubation or surgical airway protection.
- Penetrating trauma: knifes, firearm, impalement or others.
- Flail chest: more than 3 ribs with fracture in two points.
- Lung contusion: pulmonary infiltrate or condensation on initial X-rays after
trauma.
- Hemothorax type: simple (any pleural fluid detected after trauma), massive
(>1.5 Liters acute or > 200cc/h in 2-4 hours).
- Type of pneumothorax: simple (presence of aire in pleural space), hypertensive
(with hypotension and/or respiratory failure).
- Myocardial dysfunction (ventricular dysfunction detected in echocardiography
or worsening of previous cardiac dysfunction).
- Abdominal injuries grade (hepatic, spleen and renal trauma): anatomical scale
injury using the AAST-The American Association for the Surgery of Trauma.
- Pelvic fracture classification: Young-Burgees pelvic ring injury
classification.
- Neurogenic shock: bradycardia with hypoperfusion.
- Urgent surgery: first 24 hours after trauma.
- Hemorragia shock: hypoperfusion (with or without hypotension) defined by
tachicardia, coldness, peripheral vasoconstriction, need for vasopressors,
altered mental status, oliguria, hyperlactatemia or base excess deficit < - 6
due to the loss of blood after injury.
- Damage control surgery: Non-definitive surgery consisting in packing for
hemorrhage control, open abdomen, intestinal contamination control.
- Massive hemorrhage: >10 CH in the first 24 hours, life-threatening hemorrhage,
or > four blood products in the first 2 hours after admission.
- Intracranial hypertension (ICH): episode of Intracranial pressures > 20-22
mmHg maintained for more than five minutes.
- First level of ICH measures: general measures, sedation, neuromuscular
blockade, ventricular drainage, osmotherapy.
- Second level of ICH measures: decompressive craniectomy or brabiturics
administration.
- Osmotherapy: administration of hypertonic saline or mannitol during admission.

weight.

detected in CT scan managed through conservative management (no need for
surgery at least 6-8 hours).
- MNO failure: urgent laparotomy after deciding NOM.

- Abdominal compartment syndrome: results from the progression of steady-state
pressure within the abdominal cavity to a repeated pathological elevation of
pressure above 20mmHg with associated organ dysfunction.
- Early MODS (Multiorgan dysfunction syndrome): dysfunction of two or more
organs in the first 72 hours after trauma.
- Renal failure: according to AKIN guidelines.
- Trauma-induced Coagulopathy (TIC): prolongation of the prothrombin and
activated partial thromboplastin times over 1.5 times the control values, or
fibrinogen < 150 mg/dL or thrombocytopenia < 100.000/ml in the first 72 hours
after trauma.
