Ballistic peripheral nerve injuries: basic concepts, controversies, and proposal for a management strategy.

Ballistic injuries to peripheral nerves are devastating injuries frequently encountered in modern conflicts and civilian trauma centers. Such injuries often produce lifelong morbidity, mainly in the form of function loss and chronic pain. However, their surgical management still poses significant challenges concerning indication, timing, and type of repair, particularly when they are part of high-energy multi-tissue injuries. To help trauma surgeons, this article first presents basic ballistic concepts explaining different types of missile nerve lesions, described using the Sunderland classification, as well as their usual associated injuries. Current controversies regarding their surgical management are then described, including nerve exploration timing and neurolysis's relevance as a treatment option. Finally, based on anecdotal evidence and a literature review, a standardized management strategy for ballistic nerve injuries is proposed. This article emphasizes the importance of early nerve exploration and provides a detailed method for making a diagnosis in both acute and sub-acute periods. Direct suturing with joint flexion is strongly recommended for sciatic nerve defects and any nerve defect of limited size. Conversely, large defects require conventional nerve grafting, and proximal injuries may require nerve transfers, especially at the brachial plexus level. Additionally, combined or early secondary tendon transfers are helpful in certain injuries. Finally, ideal timing for nerve repair is proposed, based on the defect length, associated injuries, and risk of infection, which correlate intimately to the projectile velocity.

Do entrapment, injuries, outcomes and potential for self-extrication vary with age? A pre-specified analysis of the UK trauma registry (TARN)

BackgroundMotor vehicle collisions (MVCs), particularly those associated with entrapment, are a common cause of major trauma. Current extrication methods are focused on spinal movement minimisation and mitigation, but for many patients self-extrication may be an appropriate alternative. Older drivers and passengers are increasingly injured in MVCs and may be at an increased risk of entrapment and its deleterious effects. The aim of this study is to describe the injuries, trapped status, outcomes, and potential for self-extrication for patients following an MVC across a range of age groups.MethodsThis is a retrospective study using the Trauma Audit and Research Network (TARN) database. Patients were included if they were admitted to an English hospital following an MVC from 2012 to 2019. Patients were excluded when their outcomes were not known or if they were secondary transfers. Simple descriptive analysis was used across the age groups: 16–59, 60–69, 70–79 and 80+ years. Logistic regression was performed to develop a model with known confounders, considering the odds of death by age group, and examining any interaction between age and trapped status with mortality.Results70,027 patients met the inclusion criteria. Older patients were more likely to be trapped and to die following an MVC (p < 0.0001). Head, abdominal and limb injuries were more common in the young with thoracic and spinal injuries being more common in older patients (all p < 0.0001). No statistical difference was found between the age groups in relation to ability to self-extricate. After adjustment for confounders, the 80 + age group were more likely to die if they were trapped; adjusted OR trapped 30.2 (19.8–46), not trapped 24.2 (20.1–29.2).ConclusionsPatients over the age of 80 are more likely to die when trapped following an MVC. Self-extrication should be considered the primary route of egress for patients of all ages unless it is clearly impracticable or unachievable. For those patients who cannot self-extricate, a minimally invasive extrication approach should be employed to minimise entrapment time.

Abstract TMP33: Network Analysis Of Acute Stroke Care Systems In Korea

Purpose: Acute stroke care systems have been shifted to clusters of hospitals for cooperatively applying advanced treatment. It developed various forms of network care systems, of which measurement and evaluation are requested. Methods: Using cross-sectional national data for acute stroke care in Korea, hospital usage information after a medical contact was surveyed and transformed into node (hospital) and edge (transfer) format. Of them, dense-linked hospital groups were partitioned as a stroke community using the Louvain algorithm. It investigated the concentration, strength of connection, and functions of derived communities. Results: For six months, a total of 19113 subjects with ischemic stroke headed primarily to 1009 hospitals. They merged into 246 ASHs (acute stroke care hospitals) via 3114 (16.3%) secondary interhospital transfers. Those connections were partitioned for the 93 stroke communities (Figure A) comprising median of 9 hospitals (IQR, 5 - 14) and managed a median of 31.3 subjects per month (IQR, 18.2 - 48). They presented highly centralized structure (median group centralization degree [GDC], 1.00), which used to classify the communities (Figure B). One- or two-hospital centered communities showed similar performances of endovascular treatment (EVT) compared to lower volume or poor formatted communities. Conclusions: The network analysis method effectively contoured the high centralizing stroke communities and helped the functions on the EVT accessibility.

Missed Application of the Field Trauma Triage Standard in Secondary Interfacility Transfers of Injury

Introduction The Field Trauma Triage Standard (FTTS) is used to identify patients who would benefit from direct transfer to a lead trauma hospital (LTH). This study determined the frequency that patients who underwent secondary interfacility trauma transfer initially met the FTTS and assessed the delay to LTH. Methods Retrospective cohort study of all injured patients undergoing interfacility transfer to a LTH with Ornge, the provincial critical care transport organization in Ontario, Canada over a 1-year period. Frequency of missed FTTS application and delay to LTH were measured. Results A total of 460 adult interfacility transfer trauma patients were included in the study, of these 372 met FTTS (80.8%). The median time from initial hospital arrival to LTH was 5.7 hours for those patients requiring interfacility transport that initially would have met FTTS on scene. Conclusion Missed application of FTTS was overwhelming, occurring in over eighty percent of our population, contributing an average delay to definitive care of 5.7 hours. Older age was a commonly missed criterion. The addition of recreational vehicle collisions to the FTTS should be considered.

Secondary Transfers to University Hospitals in Patients Primarily Triaged to District General Hospitals by the Danish Helicopter Emergency Medical Service: A National Population-Based Study

ObjectiveThe aim of this study was to analyze data from the Danish helicopter emergency medical service (HEMS) database, focusing on patients undergoing a secondary transfer from district general hospitals (DGHs) to university hospitals within 24 hours of the initial emergency call. MethodsThis is a national population-based study analyzing HEMS patients undergoing a secondary transfer between October 1, 2014, and April 30, 2018. ResultsFifty-three (2.9%) of the 1,846 patients initially triaged to a DGH by the HEMS team required a secondary transfer. These 53 patients constituted 0.7% of all 7,133 patients seen by the HEMS teams during the study period. More than 60% of these patients were initially treated for either a cardiovascular or a neurologic emergency. HEMS-escorted patients had a mortality rate at day 30 of 14.3% (95% confidence interval, 4.8-38.0), and the HEMS-assisted group had a mortality rate at day 30 of 3.1% (95% CI, 0.5-20.2). ConclusionPatients initially triaged to a DGH by the HEMS teams seldomly required a secondary transfer, indicating a low degree of prehospital undertriage for direct transfer to a university hospital. Cardiovascular or neurologic emergencies were the major reasons for transportation. Mortality seems comparable with that in the general population of patients treated by the Danish HEMS teams.

A review of secondary interfacility trauma transfers meeting provincial prehospital trauma triage guidelines

Severely injured patients benefit from early identification and trauma centre treatment. Ontario has provincial prehospital trauma triage guidelines identifying patients who require direct trauma centre transport. Trauma patients not identified as meeting this provincial trauma triage standard are brought to the closest non-trauma hospital and may later be transferred to a trauma centre by a secondary interfacility transfer. Secondary interfacility transfers cause significant delays in receiving definitive care which have been associated with worse outcomes. The objective of this study was to determine the frequency that patients who underwent emergent secondary interfacility trauma transfer initially met prehospital trauma triage guidelines, as well as to assess the approximate delay to trauma centre care. Health record review of all injured patients undergoing interfacility transfer to a trauma centre by the provincial critical care transport organization in Ontario, Canada over a 1-year period. The primary outcome of interest was the frequency that patients met the triage standards and which specific criteria were satisfied. Times from patient arrival at the initial non-trauma hospital to initiation of interfacility transfer and from patient arrival at initial non-trauma hospital to arrival at trauma centre were calculated. A total of 460 were included in the study, 372 (80.8%) of whom met the prehospital triage standard. The largest missed criteria were age greater than 55years, high-risk motor vehicle collisions, and decreased Glasgow Coma Scale. The median time from initial hospital arrival to trauma centre was 5.7h for those patients requiring secondary interfacility transport. Patients who meet trauma triage criteria that end up undergoing secondary interfacility transfer experience significant delays. We recommend adding recreational vehicle collisions as a triage criterion. Emergency physicians should work with their local paramedic services to ensure severely injured patients are identified early to expedite transport.

Palsy of elbow extension

Elbow extension palsy is generally well tolerated, because when standing up, it is alleviated by gravity. In the case of trunk paralysis or brachial plexus palsy, standing is possible, thus the restoration of active elbow extension improves the hand’s positioning above the shoulder, and allows the elbow to be locked in extension, which is necessary during certain activities such as cycling. In these palsy cases, the triceps brachii will be reinnervated by nerve transfers if surgery is performed early enough before irreversible atrophy of the effector muscle sets in. In these situations, secondary tendon transfers are rarely indicated. Few available muscles can be harvested without deleterious consequences on the donor site. Finally, in patients with a very deficient upper limb but with a healthy contralateral limb, when nerve transfers are no longer possible, elbow extension will not be restored. In the tetraplegics using a wheelchair, elbow extension becomes essential for positioning the hand in space and for potentiating the transferable muscles to activate the hand. As nerve transfers have rare indications and are currently being validated in this population, palliative tendon transfers are the reference technique. They must be integrated into an overall upper limb reconstructive surgery program that takes into consideration the potentially usable muscles and the presence of elbow flexion contracture and supination deformity of the forearm. Elbow extension restoration techniques are based on the transfer of two muscles, the posterior deltoid and the biceps brachii. The first is very effective and has very specific requirements, notably good anterior stabilization of the shoulder by the pectoralis major, while the second has broader indications, notably in the case of elbow contracture and inability to stabilize the shoulder anteriorly.

The importance of the partnership between the public and private healthcare institutions to improve interhospital patient transfers

Purpose The purpose of this study/paper is to identify the importance of the partnership between the public and private health-care institutions to improve interhospital patient transfers. Scientific research and statistical data show the increased number of interhospital transportation services; therefore, timely and qualified patient transportation between different health-care institutions must be considered, the activity that directly and significantly impacts the patient’s health status and overall quality of the health-care services. The successful patient transportation from the smaller hospitals to the health-care institutions with advanced intensive care or urgent care units can be enhanced through the partnership between private and public health-care institutions. Design/methodology/approach The methodology included quantitative method, statistical data analysis and theoretical data generalization. Both primary and secondary data were collected and analyzed during the research. Expert quantification was performed using the survey research method. The survey was conducted in Lithuania. The respondents were selected to be the general managers of the health-care and urgent care institutions, the chief doctors of the reanimation and intensive care department also the chief doctors of the emergency department. Findings Because of the centralization and regionalization of health-care services, the number of patients transferred between hospitals by the emergency medical services (EMS) and personal health-care institutions has increased. University hospitals are not sufficiently prepared to accept an increasing flow of patients in accordance with the Ministry of Health orders. Not all regional or district hospitals have the right to provide such assistance, which increases transportation time and costs as well as requires additional human resources. The five EMS categories could be used to improve the patient transfer between different levels of health-care institutions. To increase partnership between private and public health-care organizations, incentives should be provided for the development of private health-care organizations, as well as encouraging actions should be taken to increase the demand for private health-care services by Lithuanian patients. Practical implications Five EMS categories identified in this paper could be used to ensure a smooth mechanism for the patient transfer between different levels of the personal health-care institutions. The proposed categories should also be used in the pre-stationary emergency phase (for reducing the interhospital patient transportation amount). Social implications Properly organized secondary and tertiary interhospital patient transfers influence the availability and quality of the EMS and reduce inequalities in the provided services and social exclusion. Originality/value This paper presents the classification of the interhospital transfer issues, determines the main reasons for the patient interhospital transfer, creates the model for the EMS patient process flows and defines five EMS categories for the assessment of patient conditions. Therefore, the research conducted and the results obtained have both theoretical and social-practical value.

Effects of state-wide implementation of the Los Angeles Motor Scale for triage of stroke patients in clinical practice

BackgroundThe prehospital identification of stroke patients with large-vessel occlusion (LVO), that should be immediately transported to a thrombectomy capable centre is an unsolved problem. Our aim was to determine whether implementation of a state-wide standard operating procedure (SOP) using the Los Angeles Motor Scale (LAMS) is feasible and enables correct triage of stroke patients to hospitals offering (comprehensive stroke centres, CSCs) or not offering (primary stroke centres, PSCs) thrombectomy.MethodsProspective study involving all patients with suspected acute stroke treated in a 4-month period in a state-wide network of all stroke-treating hospitals (eight PSCs and two CSCs). Primary endpoint was accuracy of the triage SOP in correctly transferring patients to CSCs or PSCs. Additional endpoints included the number of secondary transfers, the accuracy of the LAMS for detection of LVO, apart from stroke management metrics.ResultsIn 1123 patients, use of a triage SOP based on the LAMS allowed triage decisions according to LVO status with a sensitivity of 69.2% (95% confidence interval (95%-CI): 59.0–79.5%) and a specificity of 84.9% (95%-CI: 82.6–87.3%). This was more favourable than the conventional approach of transferring every patient to the nearest stroke-treating hospital, as determined by geocoding for each patient (sensitivity, 17.9% (95%-CI: 9.4–26.5%); specificity, 100% (95%-CI: 100–100%)). Secondary transfers were required for 14 of the 78 (17.9%) LVO patients. Regarding the score itself, LAMS detected LVO with a sensitivity of 67.5% (95%-CI: 57.1–78.0%) and a specificity of 83.5% (95%-CI: 81.0–86.0%).ConclusionsState-wide implementation of a triage SOP requesting use of the LAMS tool is feasible and improves triage decision-making in acute stroke regarding the most appropriate target hospital.

Dutch trauma system performance: Are injured patients treated at the right place?

BackgroundThe goal of trauma systems is to match patient care needs to the capabilities of the receiving centre. Severely injured patients have shown better outcomes if treated in a major trauma centre (MTC). We aimed to evaluate patient distribution in the Dutch trauma system. Furthermore, we sought to identify factors associated with the undertriage and transport of severely injured patients (Injury Severity Score (ISS) >15) to the MTC by emergency medical services (EMS). MethodsData on all acute trauma admissions in the Netherlands (2015-2016) were extracted from the Dutch national trauma registry. An ambulance driving time model was applied to calculate MTC transport times and transport times of ISS >15 patients to the closest MTC and non-MTC. A multivariable logistic regression analysis was performed to identify factors associated with ISS >15 patients’ EMS undertriage to an MTC. ResultsOf the annual average of 78,123 acute trauma admissions, 4.9% had an ISS >15. The nonseverely injured patients were predominantly treated at non-MTCs (79.2%), and 65.4% of patients with an ISS >15 received primary MTC care. This rate varied across the eleven Dutch trauma networks (36.8%-88.4%) and was correlated with the transport times to an MTC (Pearson correlation -0.753, p=0.007). The trauma networks also differed in the rates of secondary transfers of ISS >15 patients to MTC hospitals (7.8% - 59.3%) and definitive MTC care (43.6% - 93.2%). Factors associated with EMS undertriage of ISS >15 patients to the MTC were female sex, older age, severe thoracic and abdominal injury, and longer additional EMS transport times. ConclusionsApproximately one-third of all severely injured patients in the Netherlands are not initially treated at an MTC. Special attention needs to be directed to identifying patient groups with a high risk of undertriage. Furthermore, resources to overcome longer transport times to an MTC, including the availability of ambulance and helicopter services, may improve direct MTC care and result in a decrease in the variation of the undertriage of severely injured patients to MTCs among the Dutch trauma networks. Furthermore, attention needs to be directed to improving primary triage guidelines and instituting uniform interfacility transfer agreements.

Abstract P184: Effect of Acute Stroke Care Hospital Networks in Korea

Purpose: Stroke patients generally transport stroke patients either to nearest stroke hospital with secondary transfers or to hub hospitals in selective cases. This study aimed to determine the stroke community of close networks and to evaluate their role for the access the endovascular treatment (EVT). Methods: Using the nationwide acute stroke hospital (ASH) surveillance data assessed the major quality indicators of all stroke patients of South Korea, triage information both initial visit and secondary interhospital transfers were extracted according to the hospitals. Based on them, stroke community with dense linkages were partitioned using the network-based Louvain algorithm. The hierarchical model estimated the function of stroke community for the EVT. Results: For 6-month surveying period, 19113 subjects admitted to the 246 ASHs. Of them, 1831 (9.6%) were transferred from 763 adjacent facilities not ASH, while 1283 (6.7%) from the other ASHs. The algorithm determined the 113 stroke communities where composed median 7 hospitals (2 ASHs and 5 adjacent facilities) and treated about 30 subjects per month. Most of communities formed the spindle shape with higher centralization index and located within 150 Km (Figure). Stroke communities significantly affected 11% of EVT after adjustments. Conclusions: Network analysis method effectively contoured the high centralizing stroke communities and helped the functions on the EVT accessibility.

Abstract P182: Stroke Therapy in the Time of Covid-19

Background: The first surge of COVID-19 cases in Louisiana began in late March 2020 and was centered on the Greater New Orleans Area. Louisiana is divided into 9 regions; New Orleans is in Region 1. A statewide survey indicated 100% of hospitals experienced a decline in stroke presentations. We sought to determine if treatment of stroke with intravenous (IV) thrombolytic declined or was delayed relative to pre-COVID-19. We also sought to evaluate a change in door in-door out (DIDO) for secondary transfers among patients who screened positive for large vessel occlusions (LVO). Methods: Our statewide stroke registry, mandatory for hospitals attesting to Acute Stroke Ready Hospital status, was queried. We compared stroke volume, treatment rate with IV thrombolytic, treatment efficiency, and DIDO in 2019 with March 2020 and Q2 2020. Results: Monthly stroke presentations declined by 20% starting March 2020 compared to the average monthly volume in 2019. The IV thrombolytic rate was down from 10.3% to 8.8% in Q2 2020. In Q2 2020, the median door-to-needle time was 12 minutes longer than it was during 2019 and the proportion with a documented reason for delay increased from 29.1 in 2019 to 33.3% in March 2020 and 37.5% in Q2 2020. The median DIDO increased by 13 minutes compared to 2019 (129 vs 116 minutes). Discussion: Louisiana experienced a reduction in stroke presentation following the initial surge of COVID-19 cases. The treatment rate and efficiency with IV thrombolytic declined and DIDO was prolonged among patients with suspected LVO. Careful evaluation of how the stroke code processes changed in response to COVID-19 may help to recover efficiency in delivering acute stroke therapy.

Delayed Neurosurgical Intervention in Traumatic Brain Injury Patients Referred From Primary Hospitals Is Not Associated With an Unfavorable Outcome.

Background: Secondary transports of patients suffering from traumatic brain injury (TBI) may result in a delayed management and neurosurgical intervention, which is potentially detrimental. The aim of this study was to study the effect of triaging and delayed transfers on outcome, specifically studying time to diagnostics and neurosurgical management.Methods: This was a retrospective observational cohort study of TBI patients in need of neurosurgical care, 15 years and older, in the Stockholm Region, Sweden, from 2008 throughout 2014. Data were collected from pre-hospital and in-hospital charts. Known TBI outcome predictors, including the protein biomarker of brain injury S100B, were used to assess injury severity. Characteristics and outcomes of direct trauma center (TC) and those of secondary transfers were evaluated and compared. Functional outcome, using the Glasgow Outcome Scale, was assessed in survivors at 6–12 months after trauma. Regression models, including propensity score balanced models, were used for endpoint assessment.Results: A total of n = 457 TBI patients were included; n = 320 (70%) patients were direct TC transfers, whereas n = 137 (30%) were secondary referrals. In all, n = 295 required neurosurgery for the first 24 h after trauma (about 75% of each subgroup). Direct TC transfers were more severely injured (median Glasgow Coma Scale 8 vs. 13) and more often suffered a high energy trauma (31 vs. 2.9%) than secondary referrals. Admission S100B was higher in the TC transfer group, though S100B levels 12–36 h after trauma were similar between cohorts. Direct or indirect TC transfer could be predicted using propensity scoring. The secondary referrals had a shorter distance to the primary hospital, but had later radiology and surgery than the TC group (all p < 0.001). In adjusted multivariable analyses with and without propensity matching, direct or secondary transfers were not found to be significantly related to outcome. Time from trauma to surgery did not affect outcome.Conclusions: TBI patients secondary transported to a TC had surgical intervention performed hours later, though this did not affect outcome, presumably demonstrating that accurate pre-hospital triaging was performed. This indicates that for selected patients, a wait-and-see approach with delayed neurosurgical intervention is not necessarily detrimental, but warrants further research.

Utility of Severity-Based Prehospital Triage for Endovascular Thrombectomy: ACT-FAST Validation Study.

Severity-based assessment tools may assist in prehospital triage of patients to comprehensive stroke centers (CSCs) for endovascular thrombectomy (EVT), but criticisms regarding diagnostic inaccuracy have not been adequately addressed. This study aimed to quantify the benefits and disadvantages of severity-based triage in a large real-world paramedic validation of the Ambulance Clinical Triage for Acute Stroke Treatment (ACT-FAST) algorithm. Ambulance Victoria paramedics assessed the prehospital ACT-FAST algorithm in patients with suspected stroke from November 2017 to July 2019 following an 8-minute training video. All patients were transported to the nearest stroke center as per current guidelines. ACT-FAST diagnostic accuracy was compared with hospital imaging for the presence of large vessel occlusion (LVO) and need for CSC-level care (LVO, intracranial hemorrhage, and tumor). Patient-level time saving to EVT was modeled using a validated Google Maps algorithm. Disadvantages of CSC bypass examined potential thrombolysis delays in non-LVO infarcts, proportion of patients with false-negative EVT, and CSC overburdening. Of 517 prehospital assessments, 168/517 (32.5%) were ACT-FAST positive and 132/517 (25.5%) had LVO. ACT-FAST sensitivity and specificity for LVO was 75.8% and 81.8%, respectively. Positive predictive value was 58.8% for LVO and 80.0% when intracranial hemorrhage and tumor (CSC-level care) were included. Within the metropolitan region, 29/55 (52.7%) of ACT-FAST-positive patients requiring EVT underwent a secondary interhospital transfer. Prehospital bypass with avoidance of secondary transfers was modeled to save 52 minutes (95% CI, 40.0-61.5) to EVT commencement. ACT-FAST was false-positive in 8 patients receiving thrombolysis (8.1% of 99 non-LVO infarcts) and false-negative in 4 patients with EVT requiring secondary transfer (5.4% of 74 EVT cases). CSC bypass was estimated to over-triage 1.1 patients-per-CSC-per-week in our region. The overall benefits of an ACT-FAST algorithm bypass strategy in expediting EVT and avoiding secondary transfers are estimated to substantially outweigh the disadvantages of potentially delayed thrombolysis and over-triage, with only a small proportion of EVT patients missed.

Stroke Acute Management and Outcomes During the COVID-19 Outbreak: A Cohort Study From the Madrid Stroke Network.

The coronavirus disease 2019 (COVID-19) outbreak has added challenges to providing quality acute stroke care due to the reallocation of stroke resources to COVID-19. Case series suggest that patients with COVID-19 have more severe strokes; however, no large series have compared stroke outcomes with contemporary non-COVID-19 patients. Purpose was to analyze the impact of COVID-19 pandemic in stroke care and to evaluate stroke outcomes according to the diagnosis of COVID-19. Retrospective multicenter cohort study including consecutive acute stroke patients admitted to 7 stroke centers from February 25 to April 25, 2020 (first 2 months of the COVID-19 outbreak in Madrid). The quality of stroke care was measured by the number of admissions, recanalization treatments, and time metrics. The primary outcome was death or dependence at discharge. A total of 550 acute stroke patients were admitted. A significant reduction in the number of admissions and secondary interhospital transfers was found. COVID-19 was confirmed in 105 (19.1%) patients, and a further 19 patients were managed as suspected COVID-19 (3.5%). No differences were found in the rates of reperfusion therapies in ischemic strokes (45.5% non-COVID-19, 35.7% confirmed COVID-19, and 40% suspected COVID-19; P=0.265). However, the COVID-19 group had longer median door-to-puncture time (110 versus 80 minutes), which was associated with the performance of chest computed tomography. Multivariate analysis confirmed poorer outcomes for confirmed or suspected COVID-19 (adjusted odds ratios, 2.05 [95% CI, 1.12-3.76] and 3.56 [95% CI, 1.15-11.05], respectively). This study confirms that patients with COVID-19 have more severe strokes and poorer outcomes despite similar acute management. A well-established stroke care network helps to diminish the impact of such an outbreak in stroke care, reducing secondary transfers and allowing maintenance of reperfusion therapies, with a minor impact on door-to-puncture times, which were longer in patients who underwent chest computed tomography.

Endoscopic brachial plexus neurolysis in the management of infraclavicular nerve injuries due to glenohumeral dislocation

IntroductionInfraclavicular brachial plexus (BP) injury secondary to glenohumeral joint (GHJ) dislocation is a rather common complication, which may be accountable for long-lasting deficits. The purpose of this study was to assess the potential benefits of BP neurolysis in such presentation, using an endoscopic approach. Materials and methodsAll patients who underwent endoscopic BP neurolysis in the setting of infraclavicular BP palsy due to GHJ dislocation were included. Preoperative physical examination was conducted to classify the observed motor and sensitive deficits into nerves and/or cord lesions. Six weeks after the trauma, examination was repeated and endoscopic BP neurolysis was elected if no significant improvements were observed. If nerve ruptures and/or severe damages were identified during surgery, nerve reconstructions were conducted within a month; in other cases, follow-up examinations were conducted at 6 weeks, 3 and 6 months to assess the course of postoperative recovery. ResultsEleven patients were included, including 6 men and 5 women, with a mean age of 43 ± 23 years (16;73). Six patients had at least one cord involved, four patients had isolated axillary nerve palsy, and one patient had a complete BP palsy. In 7 patients with cord lesions and/or isolated axillary nerve palsy, at least grade-3 strength, according to the British Medical Research Council grading system, was noted in all affected muscles within 6 weeks following the neurolysis; after 3 months of follow-up, grade-4 strength was observed in all muscles, and all but patients but one had fully recovered within 6 months. In 3 patients with isolated axillary nerve palsy, complete nerve ruptures (n=2) and severe damages (n=1) were identified under scopic magnification; secondary nerve transfers were conducted to reanimate the axillary nerve, and all patients fully recovered within a year. In one patient with complete BP palsy, improvements started after 6 months of follow-up, and full recovery was yielded after 2 years. No intra- and/or postoperative complications were noted. ConclusionsAt the cost of minimal additional morbidity, endoscopic BP neurolysis appears to be a safe and reliable procedure to shorten recovery delays in most patients presenting with BP palsy due to GHJ dislocation.

Impact of the COVID-19 pandemic on the organisation of stroke care. Madrid Stroke Care Plan

IntroductionThe overload of the healthcare system and the organisational changes made in response to the COVID-19 pandemic may be having an impact on acute stroke care in the Region of Madrid. MethodsWe conducted a survey with sections addressing hospital characteristics, changes in infrastructure and resources, code stroke clinical pathways, diagnostic testing, rehabilitation, and outpatient care. We performed a descriptive analysis of results according to the level of complexity of stroke care (availability of stroke units and mechanical thrombectomy). ResultsThe survey was completed by 22 of the 26 hospitals in the Madrid Regional Health System that attend adult emergencies, between 16 and 27 April 2020. Ninety-five percent of hospitals had reallocated neurologists to care for patients with COVID-19. The numbers of neurology ward beds were reduced in 89.4% of hospitals; emergency department stroke care pathways were modified in 81%, with specific pathways for suspected SARS-CoV2 infection established in 50% of hospitals; and SARS-CoV2-positive patients with acute stroke were not admitted to neurology wards in 42%. Twenty four hour on-site availability of mechanical thrombectomy was improved in 10 hospitals, which resulted in a reduction in the number of secondary hospital transfers. The admission of patients with transient ischaemic attack or minor stroke was avoided in 45% of hospitals, and follow-up through telephone consultations was implemented in 100%. ConclusionsThe organisational changes made in response to the COVID-19 pandemic in hospitals in the Region of Madrid have modified the allocation of neurology department staff and infrastructure, stroke units and stroke care pathways, diagnostic testing, hospital admissions, and outpatient follow-up.

Secondary Overtriage of Trauma Patients: Analysis of Clinical and Geographic Patterns

BackgroundThe purpose of a trauma system is to match patients’ needs with hospitals' ability to care for them, recognizing that the highest levels of care cannot be provided in all locations. This means that some patients will need to be transferred from a local facility to a higher level of care. Unnecessary transfers are expensive and inconvenient to patients and families. The aim of this study is to analyze the pattern of secondary transfers in a regional trauma system. MethodsThis is a retrospective analysis. We included patients aged 16 y and older who were transferred to University of Alabama at Birmingham Hospital between 2014 and 2018. We conducted bivariate and multivariate logistic regression analysis to identify clinical and organizational predictors of requiring a critical intervention, early discharge, intensive care unit admission, and mortality. Rather than treating each injury as isolated, we analyzed injury patterns. ResultsA total of3824 patients met the inclusion criteria. Of them, 664 patients (17.4%) required a critical intervention, 635 (16.6%) were discharged within 24 h, 1356 (35.5%) were admitted to the intensive care unit, and 172 (4.0%) patients died. Univariate and multivariate analyses revealed many positive associations, with regard to injury pattern, originating center, and insurance status. ConclusionsThere are patterns in the data, and further study is required to understand drivers of secondary overtriage, and how we might be able to address this problem. Reducing the number of unnecessary transfers is a difficult task, which will require engagement at all levels of the trauma system.

Efficient Postoperative Disposition Selection in Pediatric Otolaryngology Patients: A Novel Approach.

Pediatric patients undergoing surgery on the aerodigestive tract require a wide range of postoperative airway support that may be difficult predict in the preoperative period. Inaccurate prediction of postoperative resource needs leads to care inefficiencies in the form of unanticipated intensive care unit (ICU) admissions, ICU bed request cancellations, and overutilization of ICU resources. At our hospital, inefficient utilization of pediatric intensive care unit (PICU) resources was negatively impacting safety, access, throughput, and finances. We hypothesized that actionable key drivers of inefficient ICU utilization at our hospital were operative scheduling errors and the lack of predictability of intermediate-risk patients and that improvement methodology could be used in iterative cycles to enhance efficiency of care. Through testing this hypothesis, we aimed to provide a framework for similar efforts at other hospitals. Quality improvement initiative. Plan, Do, Study, Act methodology (PDSA) was utilized to implement two cycles of change aimed at improving level-of-care efficiency at an academic pediatric hospital. In PDSA cycle 1, we aimed to address scheduling errors with surgical order placement restriction, creation of a standardized list of surgeries requiring PICU admission, and implementation of a hard stop for postoperative location in the electronic medical record surgical order. In the PDSA cycle 2, a new model of care, called the Grey Zone model, was designed and implemented where patients at intermediate risk of airway compromise were observed for 2-5 hours in the post-anesthesia care unit. After this observation period, patients were then transferred to the level of care dictated by their current status. Measures assessed in PDSA cycle 1 were unanticipated ICU admissions and ICU bed request cancellations. In addition to continued analysis of these measures, PDSA cycle 2 measures were ICU beds avoided, safety events, and secondary transfers from extended observation to ICU. In PDSA cycle 1, no significant decrease in unanticipated ICU admissions was observed; however, there was an increase in average monthly ICU bed cancellations from 36.1% to 45.6%. In PDSA cycle 2, average monthly unanticipated ICU admissions and cancelled ICU bed requests decreased from 1.3% to 0.42% and 45.6% to 33.8%, respectively. In patients observed in the Grey Zone, 229/245 (93.5%) were transferred to extended observation, avoiding admission to the ICU. Financial analysis demonstrated a charge differential to payers of $1.1 million over the study period with a charge differential opportunity to the hospital of $51,720 for each additional hospital transfer accepted due to increased PICU bed availability. Implementation of the Grey Zone model of care improved efficiency of ICU resource utilization through reducing unanticipated ICU admissions and ICU bed cancellations while simultaneously avoiding overutilization of ICU resources for intermediate-risk patients. This was achieved without compromising safety of patient care, and was financially sound in both fee-for-service and value-based reimbursement models. While such a model may not be applicable in all healthcare settings, it may improve efficiency at other pediatric hospitals with high surgical volume and acuity. N/A Laryngoscope, 131:S1-S10, 2021.

Impacto de la pandemia de COVID-19 en la organización asistencial del ictus. Plan Ictus Madrid

IntroductionThe overload of the healthcare system and the organisational changes made in response to the COVID-19 pandemic may be having an impact on acute stroke care in the Region of Madrid. MethodsWe conducted a survey with sections addressing hospital characteristics, changes in infrastructure and resources, code stroke clinical pathways, diagnostic testing, rehabilitation, and outpatient care. We performed a descriptive analysis of results according to the level of complexity of stroke care (availability of stroke units and mechanical thrombectomy). ResultsThe survey was completed by 22 of the 26 hospitals in the Madrid Regional Health System that attend adult emergencies, between 16 and 27 April 2020. Ninety-five percent of hospitals had reallocated neurologists to care for patients with COVID-19. The numbers of neurology ward beds were reduced in 89.4% of hospitals; emergency department stroke care pathways were modified in 81%, with specific pathways for suspected SARS-CoV2 infection established in 50% of hospitals; and SARS-CoV2-positive patients with acute stroke were not admitted to neurology wards in 42%. Twenty-four hour on-site availability of mechanical thrombectomy was improved in 10 hospitals, which resulted in a reduction in the number of secondary hospital transfers. The admission of patients with transient ischaemic attack or minor stroke was avoided in 45% of hospitals, and follow-up through telephone consultations was implemented in 100%. ConclusionsThe organisational changes made in response to the SARS-Co2 pandemic in hospitals in the Region of Madrid have modified the allocation of neurology department staff and infrastructure, stroke units and stroke care pathways, diagnostic testing, hospital admissions, and outpatient follow-up.
