Early tracheostomy in intensive care trauma patients improves resource utilization: a cohort study and literature review.

IntroductionDespite the integral role played by tracheostomy in the management of trauma patients admitted to intensive care units (ICUs), its timing remains subject to considerable practice variation. The purpose of this study is to examine the impact of early tracheostomy on the duration of mechanical ventilation, ICU length of stay, and outcomes in trauma ICU patients.MethodsThe following data were obtained from a prospective ICU database containing information on all trauma patients who received tracheostomy over a 5-year period: demographics, Acute Physiology and Chronic Health Evaluation II score, Simplified Acute Physiology Score II, Glasgow Coma Scale score, Injury Severity Score, type of injuries, ICU and hospital outcomes, ICU and hospital length of stay (LOS), and the type of tracheostomy procedure (percutaneous versus surgical). Tracheostomy was considered early if it was performed by day 7 of mechanical ventilation. We compared the duration of mechanical ventilation, ICU LOS and outcome between early and late tracheostomy patients. Multivariate analysis was performed to assess the impact of tracheostomy timing on ICU stay.ResultsOf 653 trauma ICU patients, 136 (21%) required tracheostomies, 29 of whom were early and 107 were late. Age, sex, Acute Physiology and Chronic Health Evaluation II score, Simplified Acute Physiology Score II and Injury Severity Score were not different between the two groups. Patients with early tracheostomy were more likely to have maxillofacial injuries and to have lower Glasgow Coma Scale score. Duration of mechanical ventilation was significantly shorter with early tracheostomy (mean ± standard error: 9.6 ± 1.2 days versus 18.7 ± 1.3 days; P < 0.0001). Similarly, ICU LOS was significantly shorter (10.9 ± 1.2 days versus 21.0 ± 1.3 days; P < 0.0001). Following tracheostomy, patients were discharged from the ICU after comparable periods in both groups (4.9 ± 1.2 days versus 4.9 ± 1.1 days; not significant). ICU and hospital mortality rates were similar. Using multivariate analysis, late tracheostomy was an independent predictor of prolonged ICU stay (>14 days).ConclusionEarly tracheostomy in trauma ICU patients is associated with shorter duration of mechanical ventilation and ICU LOS, without affecting ICU or hospital outcome. Adopting a standardized strategy of early tracheostomy in appropriately selected patients may help in reducing unnecessary resource utilization.

Critical care management of severe traumatic brain injury in adults.

Traumatic brain injury (TBI) is a major medical and socio-economic problem, and is the leading cause of death in children and young adults. The critical care management of severe TBI is largely derived from the Guidelines for the Management of Severe Traumatic Brain Injury that have been published by the Brain Trauma Foundation. The main objectives are prevention and treatment of intracranial hypertension and secondary brain insults, preservation of cerebral perfusion pressure (CPP), and optimization of cerebral oxygenation. In this review, the critical care management of severe TBI will be discussed with focus on monitoring, avoidance and minimization of secondary brain insults, and optimization of cerebral oxygenation and CPP.

Mortality reduction after implementing a clinical practice guidelines-based management protocol for severe traumatic brain injury.

INTRODUCTIONnThe objective of this study was to examine the effect of implementing a clinical practice guidelines-based management protocol on the outcome of patients with severe traumatic brain injury (TBI).nnnMETHODSnWe carried out a pre-post guideline implementation study using previously collected data in the Intensive Care Unit (ICU). All patients older than 12 years with severe TBI, defined as a Glasgow Coma Scale score of 8 or less, from March 1999 to January 2001 (control group) and from February 2001 to December 2006 (protocol group) were identified and included in this study. Patients in the protocol group were managed using a clinical practice guidelines-based management protocol, derived from the guidelines published by the Brain Trauma Foundation. Primary outcome was hospital mortality, whereas the secondary outcome was ICU mortality. To assess whether the ICU protocol might have led to an increase in the number of surviving patients with severe disability, we examined the association of the protocol use and the need for tracheostomies, mechanical ventilation duration, and ICU and hospital length of stay (LOS) among survivors.nnnRESULTSnDuring the study period, a total of 434 patients met the inclusion criteria. After adjustment for several prognostic factors, the use of protocol was independently associated with a significant reduction in hospital and ICU mortality (odds ratio, 0.45; 95% confidence interval, 0.24-0.86; and odds ratio, 0.47; 95% confidence interval, 0.23-0.96, respectively). The use of the protocol was not associated with an increase in the need for tracheostomies, mechanical ventilation duration, ICU LOS, and hospital LOS.nnnCONCLUSIONnThe protocol implementation was associated with a reduction in hospital and ICU mortality. This improvement was not associated with an increase in the frequency of tracheostomies and in ICU or hospital LOS, suggesting that the improved survival was not associated with the increased number of surviving patients with severe disability and that the functional status might have also improved.

The impact of time to tracheostomy on mechanical ventilation duration, length of stay, and mortality in intensive care unit patients

INTRODUCTIONnThis study examined the potential effects of time to tracheostomy on mechanical ventilation duration, intensive care unit (ICU), and hospital length of stay (LOS), and ICU and hospital mortality.nnnMETHODSnCohort observational study was conducted in a tertiary care medical-surgical ICU based on a prospectively collected ICU database. We included 531 consecutive patients who were admitted between March 1999 and February 2005, and underwent tracheostomy during their ICU stay. The effect of time to tracheostomy on the different outcomes assessed was estimated using multivariate regression analyses (linear or logistic, based on the type of variables). Other independent variables that were included in the analyses included selected admission characteristics.nnnRESULTSnMean +/- SD was 12.0 +/- 7.3 days for time to tracheostomy, and 23.1 +/- 18.9 days for ICU LOS. Time to tracheostomy was associated with an increased duration of mechanical ventilation (beta-coefficient = 1.31 for each day; 95% confidence interval [CI], 1.14-1.48), ICU LOS (beta-coefficient = 1.31 for each day; 95% CI, 1.13-1.48), and hospital LOS (beta-coefficient = 1.80 for each day; 95% CI, 0.65-2.94). On the other hand, time to tracheostomy was not associated with increased ICU or hospital mortality.nnnCONCLUSIONSnTime to tracheostomy was independently associated with increased mechanical ventilation duration, ICU LOS, and hospital LOS, but was not associated with increased mortality. Performing tracheostomy earlier in the course of ICU stay may have an effect on ICU resources and could entail significant cost-savings without adversely affecting patient mortality.

Permissive underfeeding versus target enteral feeding in adult critically ill patients (PermiT Trial): a study protocol of a multicenter randomized controlled trial

BackgroundNutritional support is an essential part of the management of critically ill patients. However, optimal caloric intake has not been systematically evaluated. We aim to compare two strategies of enteral feeding: permissive underfeeding versus target feeding.Method/DesignThis is an international multi-center randomized controlled trial in critically ill medical- surgical adult patients. Using a centralized allocation, 862 patients will be randomized to permissive underfeeding or target feeding. Patients in the permissive group receive 50% (acceptable range is 40% to 60%) of the calculated caloric requirement, while those in the targeted group receive 100% (acceptable range 70% to 100%) of the calculated caloric requirement. The primary outcome is 90-day all-cause mortality. Secondary outcomes include ICU and hospital mortality, 28-day, and 180-day mortality as well as health care-associated infections, organ failure, and length of stay in the ICU and hospital. The trial has 80% power to detect an 8% absolute reduction in 90-day mortality assuming a baseline risk of death of 25% at an alpha level of 0.05.DiscussionPatient recruitment started in November 2009 and is currently active in five centers. The Data Monitoring Committee advised continuation of the trial after the first interim analysis. The study is expected to finish by November 2013.Trial registrationCurrent Controlled Trials ISRCTN68144998

Profile, outcome and predictors of mortality of abdomino-pelvic trauma patients in a tertiary intensive care unit in Saudi Arabia

INTRODUCTIONnThe Kingdom of Saudi Arabia (KSA) is one of countries with the worlds highest number of deaths per 100,000 populations from road traffic accidents (RTAs). Numerous trauma victims sustain abdomino-pelvic injuries, which are associated with considerable morbidity and mortality. The purpose of this study was to describe profile, outcomes and predictors of mortality of patients with abdomino-pelvic trauma admitted to the intensive care unit (ICU) in a tertiary care trauma centre in Riyadh, KSA.nnnMETHODSnThis was a retrospective analysis of prospectively collected ICU database. All consecutive patients older than 14 years with abdomino-pelvic trauma from March 1999 to June 2013 were included. The followings were extracted: demographics, injury severity, mechanism and type of injury, associated injuries, use of vasopressors and mechanical ventilation, and worst laboratory results in the first 24h. The primary outcome was hospital mortality. We compared profile and outcomes between survivors and non-survivors and reported predictors of mortality.nnnRESULTSnOf the 11,374 trauma patients who were admitted to the hospital during the study period, 2120 (18.6%) patients had abdomino-pelvic injuries, out of which 702 (33.1%) patients were admitted to the ICU. The mean age was 30.7 (SD 14.4) years and the majority was male (89.5%). RTA was the most common cause of abdomino-pelvic trauma (70.4%). Pelvis (46.2%), liver (25.8%), and spleen (23.1%) were the most frequently injured organs; and chest (55.6%), head (41.9%), and lower extremities (27.5%) were the most commonly associated injuries. Mechanical ventilation was required in 89.6% with a mean duration of 9.1 (SD 9.2) days and emergency surgery was performed in 45.0% of the patients with prolonged ICU and hospital length of stay (10.8 [SD 10.8], 56.9 [SD 96.7] days; respectively). Of the 702 patients with abdomino-pelvic trauma, 115 (16.4%) patients did not survive. Associated head trauma and retroperitoneal haematoma, higher level of lactic acid on admission and ISS, and advanced age were potential risk factors for hospital mortality.nnnCONCLUSIONSnAbdomino-pelvic injuries are common in trauma patients, affecting mainly young male victims, and are associated with significant morbidity and mortality, and resource utilisation.

Association of preservative-free propofol use and outcome in critically ill patients

BACKGROUNDnPropofol is widely used to provide sedation to patients in the intensive care unit (ICU). This study examined whether preservative-free propofol infusion independently influences outcome in critically ill patients.nnnMETHODSnThis was a nested cohort study within a randomized controlled trial. ICU patients who received preservative-free propofol and those who did not were compared. The following data were collected: demographic information, APACHE II score, admission category, chronic severe illnesses, nutritional data, and blood glucose level and insulin dose. The main exposure was the use of preservative-free propofol infusion. The main outcomes were the occurrence of ICU-acquired infections, ICU-acquired sepsis, and ICU and hospital mortality.nnnRESULTSnA total of 523 patients were included (no propofol group, n = 399; propofol group, n = 124). After adjustment for differences in baseline characteristics, preservative-free propofol use was associated with increased risk of ICU-acquired infections (adjustedxa0odds ratio [aOR], 1.89, 95% confidence interval [CI], 1.17-3.06; P = .009) and ICU-acquired severe sepsis and septic shock (aOR, 1.91; 95% CI, 1.12-3.28; P = .02), but not with ICU or hospital mortality.nnnCONCLUSIONnPreservative-free propofol infusion in critically ill patients may be associated with increased risk of ICU-acquired infections and ICU-acquired sepsis, with no significant difference in ICU or hospital mortality. This association might have been related to the use of preservative-free preparations.

The association of duration of boarding in the emergency room and the outcome of patients admitted to the intensive care unit

BackgroundThe demand for critical care beds is increasing out of proportion to bed availability. As a result, some critically ill patients are kept in the Emergency Department (ED boarding) awaiting bed availability. The aim of our study is to examine the impact of boarding in the ED on the outcome of patients admitted to the Intensive Care Unit(ICU).MethodsThis was a retrospective analysis of ICU data collected prospectively at King Abdulaziz Medical City, Riyadh from ED between January 2010 and December 2012 and all patients admitted during this time were evaluated for their duration of boarding. Patients were stratified into three groups according to the duration of boarding from ED. Those admitted less than 6xa0h were classified as Group I, between 6 and 24xa0h, Group II and more than 24xa0h as Group III. We carried out multivariate analysis to examine the independent association of boarding time with the outcome adjusting for variables like age, sex, APACHE, Mechanical ventilation, Creatinine, Platelets, INR.ResultsDuring the study period, 940 patients were admitted from the ED to ICU, amongst whom 227 (25%) were admitted to ICU within 6xa0h, 358 (39%) within 6–24xa0h and 355 (38%) after 24xa0h. Patients admitted to ICU within 6xa0h were younger [48.7xa0±xa022.2(group I) years, 50.6xa0±xa022.6 (group II), 58.2xa0±xa020.9 (group III) (Pxa0=xa00.04)]with less mechanical ventilation duration[5.9xa0±xa08.9xa0days (Group I), 6.5xa0±xa08.1 (Group II) and 10.6xa0±xa010.5 (Group III), Pxa0=xa00.04]. There was a significant increase in hospital mortality [51(22.5), 104(29.1), 132(37.2), Pxa0=xa00.0006) and the ICU length of stay(LOS) [9.55xa0days (Group I), 9.8 (Group II) and 10.6 (Group III), (Pxa0=xa00.002)] with increase in boarding duration. In addition, the delay in admission was an independent risk factor for ICU mortality(OR for group III vs group I is 1.90, Pxa0=xa00.04) and hospital mortality(OR for group III vs Group I is 2.09, Pxa0=xa00.007).ConclusionBoarding in the ED is associated with higher mortality. This data highlights the importance of this phenomenon and suggests the need for urgent measures to reduce boarding and to improve patient flow.

Demographics and outcomes of critically ill patients transferred from other hospitals to a tertiary care academic referral center in Saudi Arabia.

BackgroundThe objective of this study was to examine the outcomes of critically ill patients who were transferred from other hospitals to a tertiary care center in Saudi Arabia as a quality improvement project.MethodsThis was a retrospective study of adult patients admitted to the medical-surgical intensive care unit (ICU) of a tertiary care hospital. Patients were divided according to the source of referral into three groups: transfers from other hospitals, and direct admissions from emergency department (ED) and from hospital wards. Standardized mortality ratio (SMR) was calculated. Multivariate analysis was performed to determine the independent predictors of mortality.ResultsOf the 7,654 patients admitted to the ICU, 611 patients (8%) were transferred from other hospitals, 2,703 (35.3%) were direct admissions from ED and 4,340 (56.7%) from hospital wards. Hospital mortality for patients transferred from other hospitals was not significantly different from those who were directly admitted from ED (35% vs. 33.1%, p = 0.37) but was lower than those who were directly admitted from hospital wards (35% vs. 51.2%, p < 0.0001). SMRs did not differ significantly across the three groups.ConclusionsCritically ill patients who were transferred from other hospitals constituted 8% of all ICU admissions. Mortality of these patients was similar to patients with direct admission from the ED and lower than that of patients with direct admission from hospital wards. However, risk-adjusted mortality was not different from the other two groups.
