Abstract
BACKGROUND Most patients with severe traumatic brain injury (sTBI) in low- or-middle-income countries and surprisingly many in high-income countries are managed without intracranial pressure (ICP) monitoring. The impact of the first published protocol (Imaging and Clinical Examination [ICE] protocol) is untested against nonprotocol management. OBJECTIVE To determine whether patients treated in intensive care units (ICUs) using the ICE protocol have lower mortality and better neurobehavioral functioning than those treated in ICUs using no protocol. METHODS This study involved nineteen mostly public South American hospitals. This is a prospective cohort study, enrolling patients older than 13 years with sTBI presenting within 24 h of injury (January 2014-July 2015) with 6-mo postinjury follow-up. Five hospitals treated all sTBI cases using the ICE protocol; 14 used no protocol. Primary outcome was prespecified composite of mortality, orientation, functional outcome, and neuropsychological measures. RESULTS A total of 414 patients (89% male, mean age 34.8 years) enrolled; 81% had 6 months of follow-up. All participants included in composite outcome analysis: average percentile (SD) = 46.8 (24.0) nonprotocol, 56.9 (24.5) protocol. Generalized estimating equation (GEE) used to account for center effects (confounder-adjusted difference [95% CI] = 12.2 [4.6, 19.8], P = .002). Kaplan-Meier 6-month mortality (95% CI) = 36% (30%, 43%) nonprotocol, 25% (19%, 31%) protocol (GEE and confounder-adjusted hazard ratio [95% CI] = .69 [.43, 1.10], P = .118). Six-month Extended Glasgow Outcome Scale for 332 participants: average Extended Glasgow Outcome Scale score (SD) = 3.6 (2.6) nonprotocol, 4.7 (2.8) protocol (GEE and confounder-adjusted and lost to follow-up-adjusted difference [95% CI] = 1.36 [.55, 2.17], P = .001). CONCLUSION ICUs managing patients with sTBI using the ICE protocol had better functional outcome than those not using a protocol. ICUs treating patients with sTBI without ICP monitoring should consider protocolization. The ICE protocol, tested here and previously, is 1 option.

Abstract
Increased intracranial pressure (ICP) is a pathologic state common to a variety of serious neurologic conditions, all of which are characterized by the addition of volume to the intracranial vault. Hence all ICP therapies are directed toward reducing intracranial volume. Elevated ICP can lead to brain damage or death by two principle mechanisms: (1) global hypoxic-ischemic injury, which results from reduction of cerebral perfusion pressure (CPP) and cerebral blood flow, and (2) mechanical compression, displacement, and herniation of brain tissue, which results from mass effect associated with compartmentalized ICP gradients. In unmonitored patients with acute neurologic deterioration, head elevation (30 degrees), hyperventilation (pCO2 26-30 mmHg), and mannitol (1.0-1.5 g/kg) can lower ICP within minutes. Fluid-coupled ventricular catheters and intraparenchymal pressure transducers are the most accurate and reliable devices for measuring ICP in the intensive care unit (ICU) setting. In a monitored patient, treatment of critical ICP elevation (>20 mmHg) should proceed in the following steps: (1) consideration of repeat computed tomography (CT) scanning or consideration of definitive neurosurgical intervention, (2) intravenous sedation to attain a quiet, motionless state, (3) optimization of CPP to levels between 70 and 110 mmHg, (4) osmotherapy with mannitol or hypertonic saline, (5) hyperventilation (pCO2 26-30 mmHg), (6) high-dose pentobarbital therapy, and (7) systemic cooling to attain moderate hypothermia (32-33°C). Placement of an ICP monitor and use of a stepwise treatment algorithm are both essential for managing ICP effectively in the ICU setting.

Abstract
There is an increased focus on evaluating processes of care, particularly in the high acuity and cost environment of intensive care. Evaluation of neurocritical-specific care and evidence-based protocol implementation are needed to effectively determine optimal processes of care and effect on patient outcomes. General quality measures to evaluate intensive care unit (ICU) processes of care have been proposed; however, applicability of these measures in neurocritical care populations has not been established. A comprehensive literature search was conducted for English language articles from 1990 to August 2013. A total of 1,061 articles were reviewed, with 145 meeting criteria for inclusion in this review. Care in specialized neurocritical care units or by neurocritical teams can have a positive impact on mortality, length of stay, and in some cases, functional outcome. Similarly, implementation of evidence-based protocol-directed care can enhance outcome in the neurocritical care population. There is significant evidence to support suggested quality indicators for the general ICU population, but limited research regarding specific use in neurocritical care. Quality indices for neurocritical care have been proposed; however, additional research is needed to further validate measures.

Abstract
Intracranial pressure (ICP) measurements are fundamental in the present protocols for intensive care of patients during the acute stage of severe traumatic brain injury. However, the latest report of a large scale randomized clinical trial indicated no association of ICP monitoring with any significant improvement in neurological outcome in severely head injured patients. Aggressive treatment of patients with therapeutic hypothermia during the acute stage of traumatic brain injury also failed to show any significant beneficial effects on clinical outcome. This lack of significant results in clinical trials has limited the therapeutic strategies available for treatment of severe traumatic brain injury. However, combined application of different types of neuromonitoring, including ICP measurement, may have potential benefits for understanding the pathophysiology of damaged brains. The combination of monitoring techniques is expected to increase the precision of the data and aid in prevention of secondary brain damage, as well as assist in determining appropriate time periods for therapeutic interventions. In this study, we have characterized the techniques used to monitor patients during the acute severe traumatic brain injury stage, in order to establish the beneficial effects on outcome observed in clinical studies conducted in the past and to follow up any valuable clues that point to additional strategies for aggressive management of these patients.

Abstract
BACKGROUND A system to provide surveillance, diagnosis, and protocolized management of surgical intensive care unit (SICU) sepsis was undertaken as a performance improvement project. A system for sepsis management was implemented for SICU patients using paper followed by a computerized system. The hypothesis was that the computerized system would be associated with improved process and outcomes. METHODS A system was designed to provide early recognition and guide patient-specific management of sepsis including (1) modified early warning signs-sepsis recognition score (MEWS-SRS; summative point score of ranges of vital signs, mental status, white blood cell count; after every 4 hours) by bedside nurse; (2) suspected site assessment (vascular access, lung, abdomen, urinary tract, soft tissue, other) at bedside by physician or extender; (3) sepsis management protocol (replicable, point-of-care decisions) at bedside by nurse, physician, and extender. The system was implemented first using paper and then a computerized system. Sepsis severity was defined using standard criteria. RESULTS In January to May 2012, a paper system was used to manage 77 consecutive sepsis encounters (3.9 ± 0.5 cases per week) in 65 patients (77% male; age, 53 ± 2 years). In June to December 2012, a computerized system was used to manage 132 consecutive sepsis encounters (4.4 ± 0.4 cases per week) in 119 patients (63% male; age, 58 ± 2 years). MEWS-SRS elicited 683 site assessments, and 201 had sepsis diagnosis and protocol management. The predominant site of infection was abdomen (paper, 58%; computer, 53%). Recognition of early sepsis tended to occur more using the computerized system (paper, 23%; computer, 35%). Hospital mortality rate for surgical ICU sepsis (paper, 20%; computer, 14%) was less with the computerized system. CONCLUSION A computerized sepsis management system improves care process and outcome. Early sepsis is recognized and managed with greater frequency compared with severe sepsis or septic shock. The system has a beneficial effect as a clinical standard of care for SICU patients. LEVEL OF EVIDENCE Therapeutic study, level III.

Abstract
OBJECTIVE Early decompressive craniectomy (DC) has been used as the first stage treatment to prevent secondary injuries in cases of severe traumatic brain injury (TBI). Postoperative management is the major factor that influences outcome. The aim of this study is to investigate the effect of postoperative management, using intracranial pressure (ICP) monitoring and including consecutive DC on the other side, on the two-week mortality in severe TBI patients treated with early DC. METHODS Seventy-eight patients with severe TBI [Glasgow Coma Scale (GCS) score <9] underwent early DC were retrospectively investigated. Among 78 patients with early DC, 53 patients were managed by conventional medical treatments and the other, 25 patients were treated under the guidance of ICP monitoring, placed during early DC. In the ICP monitoring group, consecutive DC on the other side were performed on 11 patients due to a high ICP of greater than 30 mm Hg and failure to respond to any other medical treatments. RESULTS The two-week mortality rate was significantly different between two groups [50.9% (27 patients) and 24% (6 patients), respectively, p=0.025]. After adjusting for confounding factors, including sex, low GCS score, and pupillary abnormalities, ICP monitoring was associated with a 78% lower likelihood of 2-week mortality (p=0.021). CONCLUSION ICP monitoring in conjunction with postoperative treatment, after early DC, is associated with a significantly reduced risk of death.

Abstract
To examine clinical trials and observational studies that compared use of management protocols (MPs) versus usual care for adult intensive care unit (ICU) patients with acute severe traumatic brain injury (TBI) on 6-month neurologic outcome (Glasgow Outcome Scale, GOS) and mortality, major electronic databases were searched from 1950 to April 18, 2011. Abstracts from major international meetings were searched to identify gray literature. A total of 6,151 articles were identified; 488 were reviewed in full and 13 studies were included. Data on patient and MP characteristics, outcomes and methodological quality were extracted. All 13 included studies were observational. A random effects model showed that use of MPs was associated with a favorable neurologic outcome (GOS 4 or 5) at 6 months (odds ratio [OR] and 95 % confidence interval [CI] 3.84 (2.47-5.96)) but not 12 months (OR, 95 % CI 0.87 (0.56-1.36)). Use of MPs was associated with reduced mortality at hospital discharge and 6 months (OR and 95 % CI 0.72 (0.45-1.14) and 0.33 (0.13-0.82) respectively), but not 12 months (OR, 95 % CI 0.79 (0.5-1.24)). Sources of heterogeneity included variation in study design, methodological quality, MP design, MP neurophysiologic endpoints, and type of ICU. MPs for severe TBI were associated with reductions in death and improved neurologic outcome. Although no definitive conclusions about the efficacy of MPs for severe TBI can be drawn from our study, these results should encourage the conduct of randomized controlled trials to more rigorously examine the efficacy of MPs for severe TBI.

Abstract
An acute subdural hematoma (ASDH) induces pathomechanisms which worsen outcome after traumatic brain injury, even after a small hemorrhage. Synergistic effects of a small ASDH on brain damage are poorly understood, and were studied here using neuromonitoring for 10 h in an injury model of controlled cortical impact (CCI) and ASDH. Pigs (n = 32) were assigned to 4 groups: sham, CCI (2.5 m/s), ASDH (2 ml) and CCI + ASDH. Intracranial pressure was significantly increased above sham levels by all injuries with no difference between groups. CCI and ASDH reduced ptiO(2) by a maximum of 36 ± 9 and 26 ± 11%, respectively. The combination caused a 31 ± 11% drop. ASDH alone and in combination with CCI caused a significant elevation in extracellular glutamate, which remained increased longer for CCI + ASDH. The same two groups had significantly higher peak lactate levels compared to sham. Somatosensory evoked potential (SSEP) amplitude was persistently reduced by combined injury. These effects translated into significantly elevated brain water content and histological damage in all injury groups. Thus, combined injury had stronger effects on glutamate and SSEP when compared to CCI and ASDH, but no clear-cut synergistic effects of 2 ml ASDH on trauma were observed. We speculate that this was partially due to the CCI injury severity.

Abstract
BACKGROUND Care of sepsis has been the focus of intense research and guideline development for more than two decades. With ongoing success of computer protocol (CP) technology and with publication of Surviving Sepsis Campaign (SSC) guidelines, we undertook protocol development for management of sepsis of surgical intensive care unit patients in mid-2006. METHODS A sepsis protocol was developed and implemented in The Methodist Hospital (TMH) (Houston, TX) surgical intensive care unit (27 beds) together with a sepsis research database. We compare paper-protocol (PP) (2008) and CP (2009) performance and results of the SSC guideline performance improvement initiative (2005-2008). TMH surgical intensive care unit sepsis protocol was developed to implement best evidence and to standardize decision making among surgical intensivists, nurse practitioners, and resident physicians. RESULTS The 2008 and 2009 sepsis protocol cohorts had very similar number of patients, age, % male gender, Acute Physiology and Chronic Health Evaluation scoring system II, and Sequential Organ Failure Assessment scores. The 2008 PP patients had greater baseline lactate concentration consistent with greater mortality rate. Antibiotic agents were administered to 2009 CP cohort patients sooner than 2008 PP cohort patients. Both cohorts received similar volume of intravenous fluid boluses. Comparing 6-hour resuscitation bundle compliance, the 2009 CP cohort was substantially greater than SSC eighth quarter and 2008 PP cohorts (79% vs. 31% vs. 29%), and mortality rate was much less when using the CP (14% vs. 31% vs. 24%). CONCLUSIONS Our comprehensive sepsis protocol has enabled rapid and consistent implementation of evidence-based care, and, implemented as a bedside CP, contributed to decreased mortality rate for management of surgical sepsis.

Abstract
Object
The normalization of increased intracranial pressure (ICP) in patients with severe traumatic brain injury (TBI) is assumed to limit secondary brain injury and improve outcome. Despite evidence-based recommendations for monitoring and treatment of elevated ICP, there are few studies that show an association between response to ICP-directed therapeutic regimens and adjusted mortality rate. This study utilizes a large prospective database to examine the effect of response to ICP-lowering therapy on risk of death within the first 2 weeks of injury in patients who sustained TBI and are older than 16 years.
Methods
The current study is based on 1426 patients with severe TBI (Glasgow Coma Scale [GCS] score < 9) of whom 388 were treated for elevated ICP (> 25 mm Hg) between 2000 and 2008 at 22 trauma centers enrolled in a New York State quality improvement program. This prospectively collected database also contains information including age, admission GCS score, pupillary status, CT scanning parameters, and hypotension, which are all known early prognostic indicators of death. Treatment of elevated ICP consisted of administration of mannitol, hypertonic saline, barbiturates, and/or drainage of CSF or decompressive craniectomy. The factors predicting ICP response to treatment and predicting death at 2 weeks were evaluated using logistic regression analyses.
Results
Increasing age and fewer hours of elevated ICP on Day 1 were found to be significant predictors (p = 0.001 and 0.0003, respectively) of a positive response to treatment. Response to ICP-lowering therapy (p = 0.03), younger age (p < 0.0001), fewer hours of elevated ICP (p < 0.0001), and absence of arterial hypotension on Day 1 (p = 0.001) significantly predicted reduced risk of death.
Conclusions
Patients who responded to ICP-lowering treatment had a 64% lower risk of death at 2 weeks than those who did not respond after adjusting for factors that independently predict risk of death.

Abstract
BACKGROUND Healthcare professionals are increasingly using wikis as collaborative tools to create, synthesize, share, and disseminate knowledge in healthcare. Because wikis depend on collaborators to keep content up-to-date, healthcare professionals who use wikis must adopt behaviors that foster this collaboration. This protocol describes the methods we will use to develop and test the metrological qualities of a questionnaire that will assess healthcare professionals' intentions and the determinants of those intentions to use wiki-based reminders that promote best practices in trauma care. METHODS Using the Theory of Planned Behavior, we will conduct semi-structured interviews of healthcare professionals to identify salient beliefs that may affect their future use of wikis. These beliefs will inform our questionnaire on intended behavior. A test-retest of the survey will verify the questionnaire's stability over time. We will interview 50 healthcare professionals (25 physicians and 25 allied health professionals) working in the emergency departments of three trauma centers in Quebec, Canada. We will analyze the content of the interviews and construct and pilot a questionnaire. We will then test the revised questionnaire with 30 healthcare professionals (15 physicians and 15 allied health professionals) and retest it two weeks later. We will assess the internal consistency of the questionnaire constructs using Cronbach's alpha coefficients and determine their stability with the intra-class correlation (ICC). DISCUSSION To our knowledge, this study will be the first to develop and test a theory-based survey that measures healthcare professionals' intentions to use a wiki-based intervention. This study will identify professionals' salient beliefs qualitatively and will quantify the psychometric capacities of the questionnaire based on those beliefs.

Abstract
BACKGROUND A computerized protocol was developed and used to standardize bedside clinician decision making for resuscitation of shock due to severe trauma during the first day in the intensive care unit (ICU) at a metropolitan Level I trauma center. We report overall performance of a computerized protocol for resuscitation of shock due to severe trauma, incorporating two options for resuscitation monitoring and intervention intensity, according to: (1) duration of use and (2) acceptance of computerized protocol-generated instructions. METHODS A computerized protocol operated by clinicians, using a personal computer (PC) at the bedside, was used to guide clinical decision making for resuscitation of patients meeting specific injury and shock criteria. The protocol generated instructions that could be accepted or declined. Clinician acceptance of the protocol instructions was stored by the PC software in a database for each patient. A rule-based, data-driven protocol was developed using literature evidence, expert opinion, and ongoing protocol performance analysis. Logic-flow diagrams were used to facilitate communication among multidisciplinary protocol development team members. The protocol was computerized using standard programming methods and implemented using cart-mounted PCs with a touch screen and keyboard interfaces. Protocol progression began with patient demographic data and criteria entry, confirmation of hemodynamic monitor instrumentation, request for specific hemodynamic performance data, and instructions for specific interventions (or no intervention). Use and performance of the computerized protocol was recorded in a protocol execution database. The protocol was continuously maintained with new literature evidence and database performance analysis findings. Initially implemented in 2000, the computerized protocol was refined in 2004 with two options for resuscitation intensity: pulmonary artery catheter- and central venous pressure-directed resuscitation. RESULTS Over 2 years ending at August 2006, a total of 193 trauma patients (mean Injury Severity Score was 27, survival rate 89%) were resuscitated using the computerized protocol. Protocol duration was 4400 hours or 22.7 +/- 0.4 hours per patient. The computerized protocol generated 3724 instructions (19 +/- 1 per patient) that required a bedside clinician response. In all, 94% of these instructions were accepted by the bedside clinician users. CONCLUSIONS A computerized protocol to guide decision making for trauma shock resuscitation in a Level 1 trauma center surgical ICU was developed and used as standard of care. During 2 years ending at August 2006, 94% of computer-generated instructions for specific interventions or measurements of hemodynamic performance were accepted by bedside clinicians, indicating appropriate, useful design and reliance on the computerized protocol system.

Abstract
UNLABELLED Faced with a documented crisis of patients not receiving appropriate care, there is a need to implement and refine evidence-based guidelines (EBGs) to ensure that patients receive the best care available. Although valuable in content, among their deficiencies, EBGs do not provide explicit methods to bring proven therapies to the bedside. Computerized information technology, now an integral part of the US healthcare system at all levels, presents clinicians with information from laboratory, imaging, physiologic monitoring systems, and many other sources. It is imperative that we clinicians use this information technology to improve medical care and efficacy of its delivery. If we do not do this, nonclinicians will use this technology to tell us how to practice medicine. Computerized clinical decision support (CCDS) offers a powerful method to use this information and implement a broad range of EBGs. CCDS is a technology that can be used to develop, implement, and refine computerized protocols for specific processes of care derived from EBGs, including complex care provided in intensive care units. We describe this technology as a desirable option for the trauma community to use information technology and maintain the trauma surgeon/intensivist's essential role in specifying and implementing best care for patients. We describe a process of logical protocol development based on standardized clinical decision making to enable EBGs. The resulting logical process is readily computerized, and, when properly implemented, provides a stable platform for systematic review and study of the process and interventions. CONCLUSION : CCDS to implement and refine EBG derived computerized protocols offers a method to decrease variability, test interventions, and validate improved quality of care.

Abstract
Apart from management in a specialised stroke or neurological intensive care unit, until very recently no specific therapies improved outcome after intracerebral haemorrhage (ICH). In a recent phase II trial, recombinant activated factor VII (eptacog alfa) reduced haematoma expansion, mortality, and disability when given within 4 h of ICH onset; a phase III trial (the FAST trial) is now in progress. Ventilatory support, blood-pressure reduction, intracranial-pressure monitoring, osmotherapy, fever control, seizure prophylaxis, and nutritional supplementation are the cornerstones of supportive care in intensive care units. Ventricular drainage should be considered in all stuporous or comatose patients with intraventricular haemorrhage and acute hydrocephalus. Given the lack of benefit seen in a the recent STICH trial, emergency surgical evacuation within 72 h of onset should be reserved for patients with large (>3 cm) cerebellar haemorrhages, or those with large lobar haemorrhages, substantial mass effect, and rapidly deteriorating condition.

Abstract
The management of severe head injuries in general and that of high intracranial pressure (ICP) in particular are among the most challenging tasks in neurocritical care. One of the difficulties still faced by clinicians is that of reducing variability among centers when implementing management protocols. The purpose of this paper is to propose a standardized protocol for the management of high ICP after severe head injury, consistent with recently published clinical practice guidelines and other clinical evidence such as that provided by the systematic reviews of the Cochrane Collaboration. Despite significant advances in neuromonitoring, deeper insight into the physiopathology of severe brain trauma and the many therapeutic options available, standardized protocols are still lacking. Recently published guidelines provide sketchy recommendations without details on how and when to apply different therapies. Consequently, great variability exists in daily clinical practice even though different centers apply the same evidence-based recommendations. In this paper we suggest a structured protocol in which each step is justified and integrated into an overall strategy for the management of severe head injuries. The most recent data from both the preliminary and definitive results of randomized clinical trials as well as from other sources are discussed. The main goal of this article is to provide neurotraumatology intensive care units with a unified protocol that can be easily modified as new evidence becomes available. This will reduce variation among centers when applying the same therapeutic measures. This goal will facilitate comparisons in outcomes among different centers and will also enable the implementation of more consistent clinical practice in centers involved in multicenter clinical trials.

Abstract
BACKGROUND Traumatic brain injury poses a serious public health challenge. Treatment paradigms have dramatically shifted with the introduction of the American Association of Neurologic Surgeons (AANS) Guidelines for the Management of Severe Head Injury. Implementation of the AANS guidelines positively affects patient outcomes and can be successfully introduced in a community hospital setting. METHODS Data were collected both retrospectively and prospectively from the records of all trauma patients between 1994 and 1999. A cohort of 93 patients was selected. Thirty-seven patients were treated before the implementation of the AANS guidelines, and these were statistically compared with 56 patients treated after the implementation of the guidelines. RESULTS Implementation of the recommendations in the AANS guidelines in a standardized protocol resulted in a 9.13 times higher odds ratio of a good outcome relative to the odds of a poor outcome or death compared with a group managed before the practice change. A Glasgow Coma Scale (GCS) admission score > 8 was associated with a 6.58 times higher odds ratio of a good outcome compared with a GCS admission score < or = 8. Odds ratio of a good outcome decreased by a factor of 0.92 for each year increase in age of patients starting at age 9. A dedicated neurotrauma team and comprehensive treatment algorithms are critical elements to this success. Hospital charges increased by more than $97,000 per patient, but are justifiable in the face of significantly improved outcomes. CONCLUSION Implementation of a traumatic brain injury protocol in a community hospital setting is practical and efficacious. Appropriate invasive monitoring of systemic and cerebral parameters guides care decisions. The protocol results in an increase in resource usage, but it also results in statistically improved outcomes justifying the increase in expenditures.

Abstract
Traumatic brain injury has an important socioeconomic impact in industrialized countries. However, well-conducted clinical trials are rare. Case-control studies have shown that prevention works. Pathophysiological understanding is becoming more complete as data on chemokines, local brain tissue oxygen tension and hypothermia accumulate. Multimodality monitoring will certainly assume greater importance in the future. Research with targeted therapeutic strategies indicates that secondary ischaemic insults can be prevented. Specific subgroups of patients with traumatic brain injury who will benefit from the use of hypothermia and barbiturates have been identified. Enteral feeding is the preferred nutritional strategy, and the follow-up period should be extended beyond the traditional 1 year.

Abstract
BACKGROUND Variability and logistic complexity of mechanical ventilatory support of acute respiratory distress syndrome, and need to standardize care among all clinicians and patients, led University of Utah/LDS Hospital physicians, nurses, and engineers to develop a comprehensive computerized protocol. This bedside decision support system was the basis of a multicenter clinical trial (1993-1998) that showed ability to export a computerized protocol to other sites and improved efficacy with computer- versus physician-directed ventilatory support. The Memorial Hermann Hospital Shock Trauma intensive care unit (ICU) (Houston, TX; a Level I trauma center and teaching affiliate of The University of Texas Houston Medical School) served as one of the 10 trial sites and recruited two thirds of the trauma patients. Results from the trauma patient subgroup at this site are reported to answer three questions: Can a computerized protocol be successfully exported to a trauma ICU? Was ventilator management different between study groups? Was patient outcome affected? METHODS Sixty-seven trauma patients were randomized at the Memorial Hermann Shock Trauma ICU site. "Protocol" assigned patients had ventilatory support directed by the bedside respiratory therapist using the computerized protocol. "Nonprotocol" patients were managed by physician orders. RESULTS Of the 67 trauma patients randomized, 33 were protocol (age 40 +/- 3; Injury Severity Score [ISS] 26 +/- 3; 73% blunt) and 34 were nonprotocol (age 38 +/- 2; ISS 25 +/- 2; 76% blunt). For the protocol group, the computerized protocol was used 96% of the time of ventilatory support and 95% of computer-generated instructions were followed by the bedside respiratory therapist. Outcome measures (i.e., survival, ICU length of stay, morbidity, and barotrauma) were not significantly different between groups. Fio2 > or = 0.6 and Pplateau > or = 35 cm H2O exposures were less for the protocol group. CONCLUSION A computerized protocol for bedside decision support was successfully exported to a trauma center, and effectively standardized mechanical ventilatory support of trauma-induced acute respiratory distress syndrome without adverse effect on patient outcome.

Abstract
In this article, the authors discuss the rationale for the use of computerized medication algorithms and decision support systems in the treatment of major psychiatric disorders. The field of psychopharmacology has advanced tremendously in the last two decades, with the resulting vast array of new information yielding a marked disparity between actual practice and what is commonly called "best practice." As a remedy, clinical practice guidelines and algorithms have been widely developed. These algorithms are used to disseminate up-to-date information, effect change in physician behavior, and reduce untoward variation in care. Review of the literature reveals advantages and limitations in trying to implement these paper and pencil guidelines and algorithms. Available research also suggests that computerized decision support systems have the potential to overcome such limitations, increase the use of treatment guidelines and algorithms, and improve physician adherence to recommended practices. The advantages of computerized medication algorithms and decision support systems are discussed. Finally, the computer platform elements that are necessary to make such systems effective and user-friendly are described.
