[Analysis of an incident notification system and register in a critical care unit]. / Análisis del registro de un sistema de notificación de incidentes en una unidad de cuidados críticos.

OBJECTIVE: To analyse the incident communicated through a notification system and register in a critical care unit. METHODOLOGY: A cross-sectional descriptive study was conducted by performing an analysis of the records of incidents communicated anonymously and voluntarily from January 2007 to December 2013 in a critical care unit of adult patients with severe trauma. STUDY VARIABLES: incident type and class, professional reports, and suggestions for improvement measures. A descriptive analysis was performed on the variables. RESULTS: Out of a total of 275 incidents reported, 58.5% of them were adverse events. Incident distributed by classes: medication, 33.7%; vascular access-drainage-catheter-sensor, 19.6%; devices-equipment, 13.3%, procedures, 11.5%; airway tract and mechanical ventilation, 10%; nursing care, 4.1%; inter-professional communication, 3%; diagnostic test, 3%; patient identification, 1.1%, and transfusion 0.7%. In the medication group, administrative errors accounted for a total of 62%; in vascular access-drainage-catheter-sensor group, central venous lines, a total of 27%; in devices and equipment group, respirators, a total of 46.9%; in airway self-extubations, a total of 32.1%. As regards to medication errors, 62% were incidents without damage. Incident notification by profession: doctors, 43%, residents, 5.6%, nurses, 51%, and technical assistants, 0.4%. CONCLUSIONS: Adverse events are the most communicated incidents. The events related to medication administration are the most frequent, although most of them were without damage. Nurses and doctors communicate the incidents with the same frequency. In order to highlight the low incident notification despite it being an anonymous and volunteer system, therefore, it is suggested to study measurements to increase the level of communication.

Are the paradigms in trauma disease changing?

Despite an annual trauma mortality of 5 million people worldwide, resulting in countless physical disabilities and enormous expenses, there are no standardized guidelines on trauma organization and management. Over the last few decades there have been very notorious improvements in severe trauma care, though organizational and economical aspects such as research funding still need to be better engineered. Indeed, trauma lags behind other serious diseases in terms of research and organization. The rapid developments in trauma care have produced original models available for research projects, initial resuscitation protocols and radiological procedures such as CT for the initial management of trauma patients, among other advances. This progress underscores the need for a multidisciplinary approach to the initial management and follow-up of this complicated patient population, where intensivists play a major role in both the patient admission and subsequent care at the trauma unit.

[Audit of the bedside monitor alarms in a critical care unit]. / Auditoría de las alarmas del monitor de cabecera en una unidad de cuidados críticos.

AIMS: Quantifying and evaluating the response to the bedside monitor alarms (BMA) by nurses in intensive care unit (ICU). METODOLOGY: Prospective observational study (October 2011-January 2012). Randomized blind audit on alarm management. Alarm programming and alarm limits were related to experience in ICU. We evaluated the response to BMA with the variables: alarm type (relevant/not relevant/alert) and response type. Descriptive analysis of variables for multivariate ANOVA and Chi-square test with SPSS 17.0. RESULTS: 434 audits were analyzed. The programming was: Blood pressure (BP) 88.25%, heart rate (HR) 98.62% O(2) saturation (SO) 96.79%, respiratory rate (FR) 65.75%. The alarms originated were BP 49.73%, 10.75% HR, 39.25% SO, 3.27% FS. The nurse responded to 93.3% of them and 50% were treated before 10 sec. 56.16% of the alarms were not relevant, 25.12% relevant and 18.72% alerting. 41.8% were due to handling. CONCLUSION: The alarms are programmed/attended by the nurse and there is uniformity in programming/selection limits. 25% of BMA carried therapeutic attitude.

[Pain assessment of tracheal suctioning on brain injury patients by pain behavioral indicator scale (ESCID)]. / Valoración del dolor en la aspiración de secreciones traqueales en pacientes con traumatismo craneal mediante la Escala de conductas indicadoras de dolor (ESCID).

OBJECTIVE: To assess pain response on patients with moderate to severe head injury before a common nursing procedure: tracheal suctioning. MATERIAL AND METHOD: An observational longitudinal pilot study with consecutive sampling performed from September to December of 2012. Pain was assessed by a pain behavioral indicator scale 5 minutes before, meanwhile and 15 minutes after tracheal suctioning the days 1, 3 and 6 of their intensive care unit (ICU) stay, as well as a non-painful procedure: rubbing with gauze the forearm of the patient. Pseudo-analgesia and hemodynamic variables were also recorded. Descriptive analysis of the variables, inferential statistics with t-student and Anova with SPSS 17.0; statistical tests were considered significant if the critical level observed was less than 5% (P<.05). RESULTS: Pain was assessed on 27 patients. 82% suffered from severe head trauma and 18% moderate. The average pain value during nursing procedure day 1 was 3, 18±2.6, day 3: 2, 59±2 and day 6: 3, 94±2.3. There was a significant increase in mean pain while performing suctioning during the three days of assessment (P<.05); however no significant differences between the average pain value on the three days of the assessment (P>.05) were shown. Data for the painless procedure were significantly different on day 6 (P<.05) CONCLUSION: During tracheal suctioning in patients with head injury in the first 6 days in the ICU, objective mild-moderate pain according to ESCID scale has been detected.

[Analysis of constipation in severe trauma patients]. / Análisis del estreñimiento en pacientes con traumatismo grave.

OBJECTIVES: To evaluate the incidence and risk factors of constipation in patients with severe trauma (ST). MATERIALS AND METHOD: A retrospective observational study (January-December 2011) of medical records in ST-patients with a minimum stay of 5 days was performed. Descriptive analysis of variables, inferential analysis: Student's T test and Chi-square of SPSS 17.0. Significance level P<.05. RESULTS: A total of 80 patients fulfilled the inclusion criteria, but only 69 could be analyzed. Of these, 84.06% showed constipation (according to its definition by the Work Group for Metabolism and Nutrition SEMICYUC). The most frequent day of first stool was day 7 and 9 after tolerance of enteral nutrition. Statistical significance (S.S.) of constipation was found with stay, days of sedation/relaxation/opiates, and mechanical ventilation. There was no S.S. between early enteral nutrition (EEN) and constipation (P>.05). CONCLUSIONS: There is a very high incidence of constipation in ST patients. ICU stay, days of analgesic sedation, relaxation, and mechanical ventilation are risk factors that influence the occurrence of this problem. Laxatives should be prescribed prophylactically.

[Pain behaviour indicator scale (ESCID) application in severe non-communicative trauma patients receiving mechanical ventilation]. / Aplicación de la Escala de conductas indicadoras de dolor (ESCID) en el paciente con trauma grave no comunicativo y ventilación mecánica.

OBJECTIVE: To assess pain in non-communicative patients with severe trauma undergoing mechanical ventilation prior to, during and after tracheal suctioning, mobilization and wound care. MATERIAL AND METHOD: A prospective and observational study from October to December 2011 was performed. Study variables were ESCID scale and monitoring of vital signs (blood pressure, heart rate, and respiratory rate). Data were gathering 5 minutes before, during and 15 minutes after the 3 procedures. The nursing evolutive report recorded pain assessment, administration and effectiveness of the analgesia. Descriptive analysis of variables included Student's T test/ANOVA for multivariate analysis with SPSS 17.0. RESULTS: A hundred eighty four observations: 46.8% tracheal suctioning, 38.5% mobilization and 14.7% wound care were performed in 29 patients. ESCID score was 0.4±1 before, 3.4±2.7 during and 0.4±1 after for wound care; 0.4±1.1 before, 3.6±2.2 during and 1.1±0.5 for tracheal suctioning; 0.5±1.1 before, 3±2.8 during and 0.2±0.8 after for mobilization. These increased significantly during the performance of the 3 procedures before-during/during-after: P=.000. All the hemodynamic variables were significantly modified during mobilization and tracheal suctioning: before-during/during-after: P=.000, with the exception of the cures that only affected respiratory rate. 27% of the procedures received analgesia: 9% received it before, 15% during and 3.2% after, with more analgesia being required for the wound care (33.3%). The data collected in the nursing report on the evaluation of pain/effectiveness of the analgesia showed 20.66%. CONCLUSION: An increase on the ESCID score was observed while performing the procedures.

Contralateral extraaxial hematomas after urgent neurosurgery of a mass lesion in patients with traumatic brain injury.

PURPOSE: The development of a contralateral extraaxial hematoma has repeatedly been described in small series and descriptive studies. However, the evidence available to date is limited. OBJECTIVES: To evaluate the incidence and risk factors leading to the development of a contralateral extraaxial hematoma and to describe the characteristics of cases. METHODS: A retrospective cohort study with prospective data collection was undertaken. All patients admitted to an intensive care unit (ICU) from 2006 to 2010 were studied. The inclusion criteria were as follows: severe trauma [Injury Severity Score (ISS ≥ 16)], neurosurgery (NeuroSx) in the first 24 h. The following were excluded: subacute/chronic subdural hematomas, first bilateral NeuroSx. Cases were those who required immediate contralateral NeuroSx after the first NeuroSx due to the occurrence of a new extraaxial injury or significant growth of a previous one. Controls were those patients those who did not require second NeuroSx or who required reoperation due to ipsilateral lesions. The variables considered were: demographics, neurological assessment, traumatic injuries and severity, image and surgical findings, clinical course, and outcome. Statistics analysis comprised descriptive, inferential, and multivariate analysis by logistic regression. RESULTS: A total of 120 patients were included, among which there were 11 cases (incidence 9.2 %). The cases showed a significantly higher frequency of coma or severe traumatic brain injury (TBI) at admission, contralateral injury and contralateral skull fracture in the preoperative computed tomography (CT) scan, as well as decompressive craniectomy. There were no significant differences in the severity scores, clinical course, or outcomes. The presence of contralateral fracture was identified as an independent risk factor [relative risk (RR) 47.9, 95 % confidence interval (CI) 5.2-443]. CONCLUSIONS: Contralateral extraaxial hematoma is a rare entity, although it has a high mortality rate. Therefore, it requires a high index of suspicion, especially in patients with severe TBI, with minimal contralateral injury and mainly with contralateral skull fracture on the initial CT scan.

[Development of communication tool for patient safety ("Briefing"). Experience in a trauma and emergency intensive care unit]. / Desarrollo de una herramienta de comunicación para la seguridad del paciente (Briefing). Experiencia en una unidad de cuidados intensivos de trauma y emergencias.

OBJECTIVE: To validate a safety tool used in high-risk sectors (safety briefing) in intensive care medicine. DESIGN: A prospective, observational and analytical study was carried out. SETTING: Trauma and emergency intensive care unit in a tertiary hospital. PATIENTS: Patients with severe trauma (Injury Severity Score ISS≥16). INTERVENTION: Documentation of incidents related to patient safety (PS). VARIABLES: Patients characteristics, state of the Unit, patient safety incidents, aspects of the tool (SP) and safety culture impact. RESULTS: We included 441 patients (75.15% males, mean age 39.9±17.5 years), with blunt trauma in 89% and a 10.5% mortality rate. The tool was applied in 586 out of 798 possible shifts (73.4%), and documented 942 events (2.20 incidents per patient). The incidents were more frequently associated with medication (20.7%), devices (placement 4.03%, and maintenance 17.8%) and airway and mechanical ventilation (MV) (17.09%). A correlation was established between the occurrence of incidents and the characteristics of the patient (higher Injury Severity Score, presence of MV, and continuous renal replacement therapies) and the status of the Unit (more than 6 patients per shift out of 8 possible, and holiday period). The tool significantly influenced different aspects of the safety culture of the unit (communication frequency, number of events, punitive loss and active work in PS). CONCLUSIONS: Safety briefing is a tool for the documentation of incidents that is simple and easy to use, and is useful for implementing improvements and in influencing safety culture.

[Massive transfusion predictive scores in trauma. Experience of a transfusion registry]. / Escalas predictivas de transfusión masiva en trauma. Experiencia de un registro de transfusiones.

OBJECTIVES: Our purpose is to validate previously described massive transfusion (MT) scoring in our Transfusion Trauma Registry. DESIGN: A retrospective cohort of adult trauma patients. SETTING: Trauma and Emergency Intensive Care Unit of a tertiary hospital. PATIENTS: Patients with severe trauma (injury severity score>15) admitted from October 2006 to July 2009. INTERVENTIONS: None. VARIABLES: The following MT scoring and cutoff points (CP) were evaluated: Trauma-Associated Severe Hemorrhage (TASH) CP: ≥16 and ≥18; Assessment Blood Consumption (ABC) CP: ≥2 and Emergency Transfusion Score (ETS) CP: ≥3, ≥4, ≥6. MT was defined as the transfusion of 10 units or more of packed red blood cells in the first 24 hours. We studied the sensivity (S), specifity (SP), and positive and negative predictive values (PPV, NPV), the positive and negative likehood ratios (LHR +, LHR-) and area under the receiver operating characteristic curve (ROC). RESULTS: A total of 568 patients were available for analysis; 77.6% were men, with a mean age of 41.16 ± 18 years and an ISS of 30 ± 13. 93.8% with blunt trauma. The overall MT rate was 18.8%. The best S was obtained with ETS ≥3 and best SP was obtained with TASH ≥18. ROC for different scores was: ABC: 0.779, ETS: 0. 784, TASH: 0.889. CONCLUSION: These scales can be useful for characterizing the TM population, for excluding low-risk populations, and for attempting to be objective in hematological damage control and in supporting clinical decisions, based on fe1w and easily obtainable data.

[Prediction of the clinical usefulness of routine chest X-rays in a traumatology ICU]. / Predicción de la utilidad clínica de la radiografía de tórax rutinaria en una unidad de cuidados intensivos de traumatología.

BACKGROUND: The clinical value of routine chest X-rays in critical care has been questioned, but has not been studied in the trauma environment to date. The objective of this study was to identify easy to use clinical predictors of utility in this setting. MATERIAL AND METHODS: A prospective observational study was made in an 8-bed traumatology ICU. Severe trauma patients (ISS > 15), aged 15 or older and admitted for 48 h or longer were included. Pregnant women and radiographs obtained during initial care or for reasons other than routine indication were excluded. A staff physician, separated from clinical duties, independently reviewed the films in search of changes, as described in a closed checklist. Following closed criteria, the attending physicians reported previous day clinical events and changes in clinical management after chest X-ray obtainment. Demographic and epidemiological data were also recorded. The associations among variables were studied by univariate and multivariate analysis. RESULTS: A total of 1440 routine chest X-rays were obtained from 138 consecutive patients during one year. Young males prevailed (82%; 39 ± 16 years). The most common process was severe blunt trauma (97%). Fifty-two percent suffered severe chest trauma. The mean length of stay was 12.9 ± 10.1 days. Mechanical ventilation was used in 86.8% of the cases. A median of 10.4 ± 9.3 films were obtained from each patient. A total of 14% of the X-rays showed changes, most commonly malpositioning of an indwelling device (6.8%) or infiltrates (4.9%). Those findings led to a change in care in 84.6% of the cases. Multivariate analysis identified the following significant (p < 0.05) risk factors for radiographic changes: first two days of evolution, mechanical ventilation, worsening of PaO2/FiO2, worsening of lung compliance and changes in respiratory secretions. CONCLUSIONS: Based on the results obtained, the risk of not identifying dangerous conditions by restricting routine chest X-rays prescription to the described conditions is low. Observing this policy would probably mean substantial savings and a reduction in radiation exposure.

[Evaluation of the compliance of semirecumbent position between 30-45° in intubated patients]. / Evaluación del cumplimiento de cabeceros elevados entre 30-45° en pacientes intubados.

AIMS: To determine compliance of the standard "semirecumbent position between 30-45° in patients with artificial airway (AA)". To know the opinion of the professionals on this issue. MATERIAL AND METHODS: An observational, prospective study was carried out in December 2009 in the ICU department of a tertiary hospital that excluded the limitation of therapeutic effort, prone position and antitrendelemburg. DATA COLLECTED: headrest angle, professional experience of the nurse, shift, perception of the auditor, diagnostic, type of AA (tracheostomy or endotracheal tube), mechanical ventilation (MV) (yes/no) and enteral nutrition (EN). Nurses were surveyed to verify if they knew the standard, if they complied with it, the method used and their suggestions. We used the Student's t test and ANOVA for multivariable analysis, and Fisher's χ2; p<0.05=significant. RESULTS: A total of 546 valid measurements were obtained from 53 patients, of which 40.9% had the correct semirecumbent position (30-45°). Professionals with <1 year of experience were those who raised the headrest the least, with only 26.4% of these measurements over 30°. The standard was met in only 34.8% of the neurocritical patients (NC) vs non NC (46.7%) (p<0.05). It was <30° in 29.2% of patients with tracheostomy vs 44% measurements performed on patients with TOT (p<0.05). There were no differences between shifts, the use of MV or EN. Diagnostic accuracy of the auditor: sensitivity: 91.6%; specificity: 72.5%; positive predictive value: 70.2%; negative predictive value (NPV): 92.4%. 97.9% of responders know the standard. Visual judgment was used in 97.2% of the cases. CONCLUSIONS: Measured compliance was less than 50% although the standard is well known by the nursing team. Even though the subjective perception has a high NPV, it does not achieve the standard.

[Diagnostic blood losses in severe trauma patients]. / Pérdidas sanguíneas diagnósticas en pacientes con trauma grave.

OBJECTIVE: To analyze diagnostic (blood drawings) and iatrogenic (Continuous Renal Replacement Therapy, CRRT) blood losses (BL) in severe trauma patients. METHOD: A one-year descriptive, prospective and observational study. We included patients over 15 years of age, admitted with severe trauma and who had a score of > or =16 on the Injury Severity Index (ISS). Those patients in whom limitation of therapeutic effort had been indicated were excluded. A total of 225 patients with 1619 days of evolution were analyzed for volume of BL/day/patient, type of diagnostic test, clinical outcome and utilization of CRRT. The variables were described as mean +/- standard deviation with the Student's T test. RESULTS: Average blood loss of patient per day was 55.5+/-32.2 cc. Statistically significant differences were found between the blood volume drawn when the first day was compared to the second day, 73.5+/-32.2 vs. 56.3+/-21.9 (p<0.001); clinical outcome (alive vs death) 54.8+/-33 vs. 60.7+/-24.9 (p<0.05); severity (ISS<31 or > or =31) 54.65+/-20 vs. 61.5+/-28.5 (p<0.001), No RRT vs RRT: 50.9+/-18.9 vs. 97.2+/-72.6 (p<0.001). CONCLUSIONS: The greatest diagnostic BL occurs during the resuscitation phase, in the patients who die, in those with greater severity and those undergoing CRRT.

[Pro trauma centers]. / Pro Centros de Trauma.

Trauma is a pandemic disease in the current society. In an attempt to minimize its impact, trauma care systems have been developed, the basic component being the Trauma Centers (TC). Management of the patient with severe trauma in the TC is supported by moderate scientific evidence, with many studies, but of weak quality. It is described how the volume, experience, availability of resources and other aspects are able to decrease mortality and achieve functional improvement in the TC in severe trauma patients.

[Differences in injury mechanism and pattern, severity and outcome of multiple trauma patients depending on gender]. / Diferencias en el mecanismo y patrón lesional,gravedad y evolución de los pacientes politraumatizados en función del género.

OBJECTIVE: To study de prognostic value and the difference between genders in the injury mechanism and pattern of multiple trauma patients. DESIGN: Prospective descriptive observational study. SETTING: Trauma Intensive Care Unit (ICU) of a tertiary hospital equipped with an heliport. Patients. 953 patients consecutively admitted to ICU between 2003 and 2005. MAIN VARIABLES OF INTEREST: We describe the injury pattern with MAIS of each anatomical region and use Injury Severity Score (ISS) to estimate severity and Trauma Injury Severity Score (TRISS) methodology to calculate survival probability at admission. RESULTS: Ratio male:female was 4:1, with a mean age of 38 +/- 16 years. More than 50% of patients were injured in a traffic accident. MAIS1 had a value of more than 4 in 21.3% of males and in 28.3% of females (p < 0.05); MAIS6 was more than 2 in 9.9% of males and in 16.7% of females (p < 0.01); MAIS8 was greater than 2 in 23,8% of males and in 31.8% of females (p < 0.05). Survival at discharge from ICU was 85.5% for males and 76.8% for females (p < 0.01). Mean ISS was 23.9 (23.2 for males and 26.5 for females, p < 0.01). CONCLUSION: Gender does not play a role in mortality adjusted to severity at admission. Wo - men are one fifth of all admissions but are more severe and suffer more craniocerebral injuries and these are more severe. There are few differences in injury mechanism and pattern between men and women.

Midazolam and 2% propofol in long-term sedation of traumatized critically ill patients: efficacy and safety comparison.

OBJECTIVE: We proposed to compare the efficacy and safety of midazolam and propofol in its new preparation (2% propofol) when used for prolonged, deep sedation in traumatized, critically ill patients. We also retrospectively compared 2% propofol with its original preparation, 1% propofol, used in a previous study in a similar and contemporary set of patients. DESIGN: A prospective, randomized, unblinded trial (midazolam and 2% propofol) and a retrospective, contemporary trial (2% propofol and 1% propofol). SETTINGS: A trauma intensive care unit in a tertiary university hospital. PATIENTS: A total of 63 consecutive trauma patients, admitted within a period of 5 months and requiring mechanical ventilatory support for >48 hrs, 43 of whom (73%) suffered severe head trauma. We also retrospectively compared the 2% propofol group with a series of patients in whom 1% propofol was used. INTERVENTIONS: For the prospective trial, we randomized two groups--a midazolam group with continuous administration of midazolam at dosages 0.1-0.35 mg/kg/hr, and a 2% propofol group with continuous infusion at dosages 1.5-6 mg/kg/hr. Equal dosages of analgesics were administered. Similar management protocols were applied in the 1% propofol group, used in the retrospective analysis with 2% propofol. MEASUREMENTS AND MAIN RESULTS: Epidemiologic and efficacy variables were recorded. Hemodynamic and biochemical variables were also monitored on a regular basis. Neuromonitoring was also performed on those patients with head trauma. Sedation adequacy was similar and patient behavior after drug discontinuation was not different in either prospective group (midazolam and 2% propofol). Hemodynamic or neuromonitoring variables were also similar for both groups. Triglyceride levels were significantly higher in the 2% propofol group compared with the midazolam group. A higher number of therapeutic failures because of sedative inefficacy was seen in the 2% propofol group compared with the midazolam group, especially during the first sedation days. When comparing 2% propofol and 1% propofol, a significantly higher number of therapeutic failures because of hypertriglyceridemia were found in the 1% propofol group, as opposed to a major number of therapeutic failures because of inefficacy, found in the 2% propofol group. CONCLUSIONS: Propofol's new preparation is safe when used in severely traumatized patients. Its more concentrated formula improves the lipid overload problem seen with the prolonged use of the previous preparation. Nevertheless, a major number of therapeutic failures were detected with 2% propofol because of the need for dosage increase. This fact could be caused by a different disposition and tissue distribution pattern of both propofol preparations. New studies will be needed to confirm these results.

Propofol versus midazolam: safety and efficacy for sedating the severe trauma patient.

UNLABELLED: Previous studies have compared sedation profiles with midazolam (Mz) and propofol (Pf), particularly in heterogeneous populations of patients. Decreases in blood pressure and heart rate have been reported after the administration of propofol. These side effects are potentially deleterious in severe trauma patients, particularly in patients with head trauma. To assess the safety and efficacy of Mz and Pf, alone or in combination, in the prolonged sedation of severe trauma patients, we designed a prospective, controlled, randomized, study. One hundred consecutively admitted trauma patients requiring mechanical ventilation and sedation for more than 48 h were studied. Patients were sedated according to three different protocols based on the continuous i.v. administration of Mz alone, Pf alone, and Mz in combination with Pf. All patients received morphine chloride. Safety and efficacy were assessed during the sedation and wake-up periods according to clinical and laboratory variables. Cerebral hemodynamics were also studied in patients with head trauma. Patients were sedated for 6.3 +/- 4.0 days (mean +/- SD). All three sedation regimens were equally efficacious in achieving the desired sedation goal. The incidence of adverse events during the sedation period was also similar. In head trauma patients with intracranial pressure (ICP) monitoring, we did not find differences in ICP, cerebral perfusion pressure, or jugular venous oxygen saturation among the three groups. The serum triglyceride concentration was significantly higher in the Pf group. Wake-up time was significantly shorter in the Pf group. We conclude that both Mz and Pf are safe and efficacious in the sedation of severe trauma patients. The use of Pf in these patients is associated with a high incidence of hypertriglyceridemia and a shorter wake-up time. IMPLICATIONS: In a prospective, controlled, randomized study, we confirmed the safety and efficacy of midazolam and propofol, alone or in combination, in the prolonged sedation of a homogeneous group of severe trauma patients, particularly in patients with head trauma. The propofol group had shorter wake-up times and higher triglyceride levels.
