New Immobilization Guidelines Change EMS Critical Thinking in Older Adults With Spine Trauma.

OBJECTIVE: The impact of immobilization techniques on older adult trauma patients with spinal injury has rarely been studied. Our advisory group implemented a change in the immobilization protocol used by emergency medical services (EMS) professionals across a region encompassing 9 trauma centers and 24 EMS agencies in a Rocky Mountain state using a decentralized process on July 1, 2014. We sought to determine whether implementing the protocol would alter immobilization methods and affect patient outcomes among adults ≥60 years with a cervical spine injury. METHODS: This was a 4-year retrospective study of patients ≥60 years with a cervical spine injury (fracture or cord). Immobilization techniques used by EMS professionals, patient demographics, injury characteristics, and in-hospital outcomes were compared before (1/1/12-6/30/14) and after (7/1/14-12/31/15) implementation of the Spinal Precautions Protocol using bivariate and multivariate analyses. RESULTS: Of 15,063 adult trauma patients admitted to nine trauma centers, 7,737 (51%) were ≥60 years. Of those, 237 patients had cervical spine injury and were included in the study; 123 (51.9%) and 114 (48.1%) were transported before and after protocol implementation, respectively. There was a significant shift in the immobilization methods used after protocol implementation, with less full immobilization (59.4% to 28.1%, p < 0.001) and an increase in the use of both a cervical collar only (8.9% to 27.2%, p < 0.001) and not using any immobilization device (15.5% to 31.6%, p = 0.003) after protocol implementation. While the proportion of patients who only received a cervical collar increased after implementing the Spinal Precautions Protocol, the overall proportion of patients who received a cervical collar alone or in combination with other immobilization techniques decreased (72.4% to 56.1%, p = 0.01). The presence of a neurological deficit (6.5% vs. 5.3, p = 0.69) was similar before and after protocol implementation; in-hospital mortality (adjusted odds ratio = 0.56, 95% confidence interval: 0.24-1.30, p = 0.18) was similar post-protocol implementation after adjusting for injury severity. CONCLUSIONS: There were no differences in neurologic deficit or patient disposition in the older adult patient with cervical spine trauma despite changes in spinal restriction protocols and resulting differences in immobilization devices.

How a CT-Direct Protocol at an American Comprehensive Stroke Center Led to Door-to-Needle Times Less Than 30 Minutes.

BACKGROUND AND PURPOSE: The safety and efficacy of intravenous tissue plasminogen activator (IV tPA) following acute ischemic stroke (AIS) is dependent on its timely administration. In 2014, our Comprehensive Stroke Center designed and implemented a computed tomography-Direct protocol to streamline the evaluation process of suspected patients with AIS, with the aim of reducing door-to-needle (DTN) times. The objectives of our study were to describe the protocol development and implementation process, and to compare DTN times and symptomatic intracranial hemorrhage (sICH) rates before and after protocol implementation. METHODS: Data were prospectively collected for patients with AIS receiving IV tPA between January 1, 2010, and May 31, 2015. The DTN times, examined as median times and time treatment windows, and sICH rates were compared pre- and postimplementation. RESULTS: Two hundred ninety-five patients were included in the study. After protocol implementation, median DTN times were significantly reduced (38 vs 28 minutes; P < .001). The distribution of patients treated in the three time treatment windows described below changed significantly, with an increase in patients with DTN times of 30 minutes or less, and a decrease in patients with DTN times 31 to 60 minutes and over 60 minutes (P < .001). There were two cases of sICH prior to implementation and one sICH case postimplementation. CONCLUSIONS: The implementation of a protocol that streamlined the processing of suspected patients with AIS significantly reduced DTN time without negatively impacting patient safety.

Developing, Implementing, and Evaluating a Nurse-Driven Rapid Reversal Protocol for Patients With Traumatic Intracerebral Hemorrhage in the Presence of Preinjury Warfarin.

Warfarin-related traumatic intracerebral hemorrhage (ICH) is often fatal, yet timely evaluation and treatment can improve outcomes. Our study describes the process of developing and implementing a protocol to guide the care of patients with traumatic brain injury (TBI) on preinjury warfarin developed by nurses across several service lines at our Level I trauma center over a 6-month period. Further, we evaluated its efficacy by examining records of adult patients with TBI on preinjury warfarin admitted 1 year before and after protocol implementation. Efficacy was defined as activation rates, receipt and time to head computed tomography (CT) scan and international normalization ratio (INR), and receipt and time to fresh frozen plasma (FFP) administration in patients with ICH with an INR more than 1.5, as per protocol. A subset analysis examined patients with and without an ICH. Outcomes were compared using univariate analyses. One hundred seventy-eight patients were included in the study; 90 (50.6%) were admitted before and 88 (49.4%) after implementation. After implementation, there were improvements in activation rates (34.4% vs. 65.9%; p < .001), the frequency of head CT scans (55.6% vs. 83.0%; p < .001), time to INR (24.0 min vs. 15.0 min; p < .05), and, for patients with ICH with an INR 1.5 or more, decreased time to FFP (157.0 vs. 90.5; p < .05). In conclusion, our protocol led to a more efficient process of care for patients with TBI on warfarin. We believe the implementation process, managed by a dedicated group of nurses across several service lines, substantially contributed to the success of the protocol.

Lights and Siren Transport and the Need for Hospital Intervention in Trauma Patients.

Emergent ambulance transportation is associated with increased risk of collision, injury, and death for EMS professionals, patients, and the general public. Time saved using lights and siren (L&S) is typically small, and often provides minimal clinical benefit. Our objective was to investigate the frequency of L&S transports, describe the precision of the decision to employ L&S to predict the need for a time critical hospital intervention (TCHI) within 15 minutes of hospital arrival, identify clinical predictors of a TCHI, and compare clinical outcomes in patients transported by Emergency Medical Services (EMS) with and without L&S in a trauma-specific population. EMS patient care reports and trauma registry data were retrospectively reviewed for trauma patients consecutively transported from the field by three EMS agencies to three trauma centers within urban and suburban settings over a two-year period. TCHIs were collaboratively developed by the study team. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were utilized to report the precision of the decision to employ L&S to predict the need of a TCHI. Univariate and multivariate analyses determined predictors of a TCHI and compared clinical outcomes. 2,091 patients were included in the study. Of the 19.8% of patients transported with L&S, 22.9% received a TCHI. The most common TCHI was airway or respiratory procedures (87.2% of all TCHI's). The sensitivity and specificity of L&S to predict the need for a TCHI was 87.2% (95% CI 79.4-92.8) and 84.0% (95% CI 82.2-85.5), respectively. PPV was 23.0% (95% CI 23.53-38.01); NPV was 99.2% (95% CI 98.6-99.6). L&S was predictive for the need for a TCHI (p < 0.001), as was abnormal Glasgow Coma Score (p < 0.001), abnormal systolic blood pressure and age (p < 0.05 for all). Among patients that received a TCHI, over a third that were transported with L&S (36.8%) expired, compared with two of 14 patients (14.3%) not transported L&S. EMS professionals in this study demonstrated a high ability to discern which trauma patients did not require L&S. Nevertheless, L&S transport resulted in a TCHI less than one quarter of the time, suggesting an opportunity for further reduction of L&S transports in trauma patients.

Does diabetes type increase the odds of venous thromboembolism following traumatic injury?

BACKGROUND: Venous thromboembolism (VTE) remains a clinically significant complication after trauma even though screening and prophylaxis strategies for at-risk patients have substantially reduced incidence. Our study sought to determine if diabetes, a condition that promotes thrombi formation, is associated with developing a VTE in trauma patients. METHODS: The registries of 2 level I and a level II trauma centers were retrospectively reviewed for consecutively admitted trauma patients over a 6-year period. Demographics, VTE risk factors, injury characteristics, and VTE incidence were univariately compared between patients with insulin-dependent diabetes mellitus (IDDM), non-insulin-dependent diabetes mellitus (NIDDM), and no diabetes. Stepwise logistic regression was performed to identify independent predictors of VTE; results were further stratified by age (<65 and ≥65 years) and presented as adjusted ORs (AOR). RESULTS: Of the 26 934 total patients, 779 (2.9%) had IDDM, 2052 (7.6%) had NIDDM, and the remaining 89.5% were without diabetes. VTE incidence was 3.6%, 2.4%, and 2.2%, in IDDM, NIDDM, and non-diabetes, respectively (p=0.02). After adjustment for established and significant risk factors, neither IDDM (AOR=1.43, 95% CI 0.95 to 2.15, p=0.09) nor NIDDM (AOR=1.03, 95% CI 0.75 to 1.40, p=0.88) was associated with increased odds of developing a VTE. Patients ≥65 years developed VTE more frequently than those <65 years (2.5% vs 2.1%, p=0.04). Among patients <65 years, IDDM was significantly predictive of VTE (AOR=1.86, 95% CI 1.01-3.41, p=0.045), but NIDDM was not. For patients ≥65 years, neither type of diabetes was predictive of VTE. CONCLUSIONS: VTE incidence was ∼2 times higher among injured patients <65 years with IDDM versus no diabetes. Overall, we did not find an increased risk of VTE in patients with any diabetes. Additional studies are needed before a recommendation on VTE screening or prophylaxis in IDDM can be made. LEVEL OF EVIDENCE: Level III, therapeutic/care management.

The relationship between patient volume and mortality in American trauma centres: a systematic review of the evidence.

OBJECTIVE: To synthesise published and unpublished findings examining the relationship between institutional trauma centre volume or trauma patient volume per surgeon and mortality. BACKGROUND: Evidence on the relationship between patient volume and survival in trauma patients is inconclusive in the literature and remains controversial. METHODS: A literature search was performed to identify studies published between 1976 and 2013 via MEDLINE (Pubmed) and the Cumulative Index to Nursing and Allied Health Literature (EbscoHost) as well as footnote chasing. Abstracts from appropriate conferences and ProQuest Dissertations and Theses were also searched. Inclusion criteria required studies to be original research published in English that examined the relationship between mortality and either institutional or per surgeon volume in American trauma centres. We employed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement checklist and flowchart. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was employed to rate the quality of the evidence. RESULTS: Of 1392 studies reviewed, 19 studies met defined inclusion criteria; all studies were retrospective. The definition of volume was heterogeneous across the studies. Patient population and analysis methods also varied across the studies. Sixteen studies (84%) examined the relationship between institutional trauma centre volume and mortality. Of the 16 studies, 12 examined the volume of severely injured patients and eight examined overall trauma patient volume. High institutional volume was associated with at least somewhat improved mortality in ten of 16 studies (63%); however, nearly half of these studies found only some subpopulations experienced benefits. In the remaining six studies, volume was not associated with any benefits. Four studies (25%) analysed the impact of surgeon volume on mortality. High volume per surgeon was associated with improved mortality in only one of four studies (25%). CONCLUSIONS: The studies were extremely heterogeneous, thus definitive conclusions cannot be drawn regarding optimal volume before a clear advantage in survival is observed. A prospective study defining volume as a continuous variable is warranted to support current admission criteria for American trauma patients.

e-ageing: development and evaluation of a flexible online geriatric medicine educational resource for diverse learners.

AIMS: To determine preferred content and format for online education modules in aged care among inter-professional learners; to develop resources that meet user preferences. METHODS: Stakeholders were interviewed. A survey was administered to all health/medical students and teachers at The University of Western Australia. An iterative process was used to develop modules, and user feedback was collated. RESULTS: The educational needs of each discipline related primarily to foundation level knowledge in major aged care topics. Stakeholders sought modules incorporating communication skills, cultural and social issues and the importance of a multidisciplinary approach to aged care. Students from all disciplines sought online materials that are interactive, engaging, case-based and locally relevant. Online modules were developed. Evaluation of the modules by users has been strongly positive. CONCLUSION: There was consensus regarding the major curricular areas that online resources should encompass. The e-ageing modules developed in this project have been evaluated positively by users.

Developing a rural trauma outreach program: the experience of a major health care network.

This study describes the process undertaken by a private health care network to develop and implement an outreach program for rural level III to V trauma centers. The program provided individualized trauma program support to 18 rural out-of-network facilities. A case study and participant satisfaction survey demonstrate the experiences of rural trauma nurse coordinators working with the program. The Trauma Outreach Program presents a solution to enhance the effectiveness of regional trauma systems, lift the burden on rural facilities, and improve care for the injured patient.

Students and teachers' preferences for undergraduate dementia education in Western Australia.

Medical graduates require positive attitudes toward older people with cognitive impairment, in addition to knowledge and skills in the diagnosis and management of dementia. The Student Training Project in Dementia (STriDE) project was conducted to ensure that these needs are met through curricula in Western Australian medical schools. Two medical schools in Perth, Western Australia, participated. Mixed methods were utilized comprising a) focus groups and interviews and b) a survey of teachers and students. Participants recommended clearer structure and standardization in the curriculum to ensure that all students receive similar educational experiences regardless of hospital placement. Both teachers, and to a lesser extent students, held positive attitudes toward older people. Teachers tended to be more dissatisfied with current curricula than students. Teachers and learners endorsed a broad range of teaching and learning methods, assessments, and skills/competencies. The results of this study present major challenges for professional entry dementia education given the breadth, flexibility, and depth of dementia education recommended by teachers and learners.
