Mortality prediction using TRISS methodology in the Spanish ICU Trauma Registry (RETRAUCI).

OBJECTIVES: To validate Trauma and Injury Severity Score (TRISS) methodology as an auditing tool in the Spanish ICU Trauma Registry (RETRAUCI). DESIGN: A prospective, multicenter registry evaluation was carried out. SETTING: Thirteen Spanish Intensive Care Units (ICUs). PATIENTS: Individuals with traumatic disease and available data admitted to the participating ICUs. INTERVENTIONS: Predicted mortality using TRISS methodology was compared with that observed in the pilot phase of the RETRAUCI from November 2012 to January 2015. Discrimination was evaluated using receiver operating characteristic (ROC) curves and the corresponding areas under the curves (AUCs) (95% CI), with calibration using the Hosmer-Lemeshow (HL) goodness-of-fit test. A value of p<0.05 was considered significant. MAIN VARIABLES OF INTEREST: Predicted and observed mortality. RESULTS: A total of 1405 patients were analyzed. The observed mortality rate was 18% (253 patients), while the predicted mortality rate was 16.9%. The area under the ROC curve was 0.889 (95% CI: 0.867-0.911). Patients with blunt trauma (n=1305) had an area under the ROC curve of 0.887 (95% CI: 0.864-0.910), and those with penetrating trauma (n=100) presented an area under the curve of 0.919 (95% CI: 0.859-0.979). In the global sample, the HL test yielded a value of 25.38 (p=0.001): 27.35 (p<0.0001) in blunt trauma and 5.91 (p=0.658) in penetrating trauma. TRISS methodology underestimated mortality in patients with low predicted mortality and overestimated mortality in patients with high predicted mortality. CONCLUSIONS: TRISS methodology in the evaluation of severe trauma in Spanish ICUs showed good discrimination, with inadequate calibration - particularly in blunt trauma.

Epidemiology of severe trauma in Spain. Registry of trauma in the ICU (RETRAUCI). Pilot phase. / Epidemiología del trauma grave en España. REgistro de TRAuma en UCI (RETRAUCI). Fase piloto.

OBJECTIVE: To describe the characteristics and management of severe trauma disease in Spanish Intensive Care Units (ICUs). Registry of trauma in the ICU (RETRAUCI). Pilot phase. DESIGN: A prospective, multicenter registry. SETTING: Thirteen Spanish ICUs. PATIENTS: Patients with trauma disease admitted to the ICU. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Epidemiology, out-of-hospital attention, registry of injuries, resources utilization, complications and outcome were evaluated. RESULTS: Patients, n=2242. Mean age 47.1±19.02 years. Males 79%. Blunt trauma 93.9%. Injury Severity Score 22.2±12.1, Revised Trauma Score 6.7±1.6. Non-intentional in 84.4% of the cases. The most common causes of trauma were traffic accidents followed by pedestrian and high-energy falls. Up to 12.4% were taking antiplatelet medication or anticoagulants. Almost 28% had a suspected or confirmed toxic influence in trauma. Up to 31.5% required an out-of-hospital artificial airway. The time from trauma to ICU admission was 4.7±5.3hours. At ICU admission, 68.5% were hemodynamically stable. Brain and chest injuries predominated. A large number of complications were documented. Mechanical ventilation was used in 69.5% of the patients (mean 8.2±9.9 days), of which 24.9% finally required a tracheostomy. The median duration of stay in the ICU and in hospital was 5 (range 3-13) and 9 (5-19) days, respectively. The ICU mortality rate was 12.3%, while the in-hospital mortality rate was 16.0%. CONCLUSIONS: The pilot phase of the RETRAUCI offers a first impression of the epidemiology and management of trauma disease in Spanish ICUs.

Management of temperature control in post-cardiac arrest care: an expert report. / Manejo con control de temperatura en los cuidados posparada cardiaca: documento de expertos.

Targeted temperature management (TTM) through induced hypothermia (between 32-36 oC) is currently regarded as a first-line treatment during the management of post-cardiac arrest patients admitted to the Intensive Care Unit (ICU). The aim of TTM is to afford neuroprotection and reduce secondary neurological damage caused by anoxia. Despite the large body of evidence on its benefits, the TTM is still little used in Spain. There are controversial issues referred to its implementation, such as the optimal target body temperature, timing, duration and the rewarming process. The present study reviews the best available scientific evidence and the current recommendations contained in the international guidelines. In addition, the study focuses on the practical implementation of TTM in post-cardiac arrest patients in general and cardiological ICUs, with a discussion of the implementation strategies, protocols, management of complications and assessment of the neurological prognosis.

Combined Thorax-Abdomen Extraction in Controlled Cardiac Death (Maastricht Type III) Donors.

Donation after circulatory death (DCD) or controlled cardiac death (Maastricht type III donors) is that in which the irreversible cessation of circulatory and respiratory function occurs after the withdrawal of life-sustaining therapies. The shortage of available donor lungs has prompted the development of programs of controlled DCD for lung transplantation. The combined thorax-abdomen extraction in these cases is carried out only in a few centers in Spain, being even more exceptional considering the combined use of super rapid lung extraction with abdominal normothermic regional perfusion. The success achieved with the first cases of combined thorax-abdomen extraction in Maastricht type III donors in Navarra shows that it is a feasible and safe procedure.

[Combined thorax-abdomen extraction in a Maastricht type III donor]. / Extracción combinada tórax-abdomen en un donante en asistolia tipo III de Maastricht.

Donation after circulatory death (Maastricht type III donation) or controlled cardiac death refers to the retrieval of organs for transplantation purposes following death confirmed using circulatory criteria after the withdrawal of life support. The persistent shortfall in organ availability has prompted the development of donation programs following circulatory death for lung transplantation. The combined thorax-abdomen extraction in these cases is carried out in only twelve centres in Spain, while the combined use of abdominal normothermic regional perfusion (NRP) is even more exceptional. The first case of pulmonary and abdominal extraction in a Maastricht type III donor in Navarre with this type of preservation techniques is a milestone and the success achieved shows that it is a feasible and safe procedure.

[Clinical course of induced hypothermia after cardiac arrest]. / Trayectoria clínica de hipotermia terapéutica posparada cardiaca.

INTRODUCTION: Cardiac Arrest is a major health problem because of its high mortality and neurological effects due to hypoxia. Based on the Scientific Societies recommendations and Scientific Evidence, our hospital began to apply Mild Hypothermia in 2006. OBJECTIVE OF THIS CLINICAL COURSE: To standardize the application of the non-invasive Induction and Maintenance Hypothermia System (Arctic-Sun), to avoid the variability of the clinical practice, and to ensure patient quality of care and safety. METHODOLOGY: A review was made of the literature and protocols of the Health Care Centers where hypothermia is used. The clinical records of the patients in whom this technique was used were analyzed. Meetings were held with the professionals in order to reach a consensus. STAFF: Doctors, Nurses and Nursing assistants. TECHNIQUE: The activities in each phase were described: preparation and patient monitoring, cooling device, programming, induction and maintenance of hypothermia and controlled rewarming until normothermia is reached.
