Telemedicine-assisted treatment of patients with intracerebral hemorrhage

Hypertensive intracerebral hemorrhage: Which one should we choose between laser navigation and 3D navigation mold?

Background

Hypertensive intracerebral hemorrhage (HICH) is a severe life-threatening disease, and its incidence has gradually increased in recent years. Due to the particularity and diversity of its bleeding sites, the early treatment of hematoma needs to be more meticulous and accurate, and minimally invasive surgery is often one of the measures that are commonly adopted now. The lower hematoma debridement and the navigation template created by 3D printing technology were compared in the external drainage of a hypertensive cerebral hemorrhage. Then the effect and feasibility of the two operations were explicitly evaluated.

Material and methods

We performed a retrospective analysis of all eligible patients with HICH who underwent laser-guided hematoma evacuation or hematoma puncture under 3D-navigated molds at the Affiliated Hospital of Binzhou Medical University from January 2019 to January 2021. A total of 43 patients were treated. Twenty-three patients were treated with laser navigation-guided hematoma evacuation (group A); 20 patients were treated with 3D navigation minimally invasive surgery (group B). A comparative study was conducted between the two groups to evaluate the preoperative and postoperative conditions.

Results

The preoperative preparation time of the laser navigation group was significantly shorter than that of the 3D printing group. The operation time of the 3D printing group was better than that of the laser navigation group (0.73 ± 0.26 h vs. 1.03 ± 0.27 h P = 0.00070). In the improvement in the short-term postoperatively, there was no statistically significant difference between the laser navigation group and the 3D printing group (Median hematoma evacuation rate P = 0.14); And in the three-month follow-up NIHESS score, there was no significant difference between the two (P = 0.82).

Conclusion

Laser-guided hematoma removal is more suitable for emergency operations, with real-time navigation and shortened preoperative preparation time; hematoma puncture under a 3D navigation mold is more personalized and shortens the intraoperative time course. There was no significant difference in therapeutic effect between the two groups.

Telemedicine in Neurosurgery: Lessons Learned from a Systematic Review of the Literature for the COVID-19 Era and Beyond

BACKGROUND

Evolving requirements for patient and physician safety and rapid regulatory changes have stimulated interest in neurosurgical telemedicine in the COVID-19 era.

OBJECTIVE

To conduct a systematic literature review investigating treatment of neurosurgical patients via telemedicine, and to evaluate barriers and challenges. Additionally, we review recent regulatory changes that affect telemedicine in neurosurgery, and our institution's initial experience.

METHODS

A systematic review was performed including all studies investigating success regarding treatment of neurosurgical patients via telemedicine. We reviewed our department's outpatient clinic billing records after telemedicine was implemented from 3/23/2020 to 4/6/2020 and reviewed modifier 95 inclusion to determine the number of face-to-face and telemedicine visits, as well as breakdown of weekly telemedicine clinic visits by subspecialty.

RESULTS

A total of 52 studies (25 prospective and 27 retrospective) with 45 801 patients were analyzed. A total of 13 studies were conducted in the United States and 39 in foreign countries. Patient management was successful via telemedicine in 99.6% of cases. Telemedicine visits failed in 162 cases, 81.5% of which were due to technology failure, and 18.5% of which were due to patients requiring further face-to-face evaluation or treatment. A total of 16 studies compared telemedicine encounters to alternative patient encounter mediums; telemedicine was equivalent or superior in 15 studies. From 3/23/2020 to 4/6/2020, our department had 122 telemedicine visits (65.9%) and 63 face-to-face visits (34.1%). About 94.3% of telemedicine visits were billed using face-to-face procedural codes.

CONCLUSION

Neurosurgical telemedicine encounters appear promising in resource-scarce times, such as during global pandemics.

Clinicians' User Experience of Telemedicine in Neurosurgery During COVID-19

BACKGROUND

Restricted access to hospitals due to the 2019 novel coronavirus disease (COVID-19) pandemic has significantly altered practice patterns for elective neurosurgical care. Particularly, telemedicine has become the primary modality of patient visits for nonemergent conditions. This study aimed to characterize user experiences of neurosurgeons and advanced practice providers focusing on perceived utility and barriers of telemedicine in management of elective neurosurgical patients during COVID-19.

METHODS

An online survey was sent to clinicians involved in neurosurgical care using telemedicine with questions focusing on frequency of utilization, duration of patient encounters, benefits of telemedicine, and barriers to current forms of remote patient visits. Survey responses were stratified by clinical position (neurosurgeon vs. advanced practice provider) and subspecialty focus (cranial vs. spinal neurosurgery).

RESULTS

The survey was completed by 14 of 17 eligible clinicians. Respondents included 10 neurosurgeons and 4 APPs with 57% specializing in cranial neurosurgery and 43% specializing in spinal neurosurgery. During the COVID-19 period, 78% of respondents used teleconference/video conference visits multiple times in a week, and 86% planned to continue using telemedicine after the pandemic. The most common barrier for telemedicine was the inability to perform a neurological examination, while the most common perceived benefit was increased convenience for patients.

CONCLUSIONS

During the COVID-19 period, telemedicine was heavily relied on to ensure the continuation of perioperative care for patients with elective neurosurgical pathologies. While clinicians identified numerous barriers for current telemedicine platforms, the use of telemedicine will likely continue, as it has provided unique benefits for patients, clinicians, and hospitals.

Quantifying the Impact of Acute Stroke System of Care Transfer Protocols on Patient Outcomes

BACKGROUND

We quantify the impact of implementing a stroke system of care requiring transport of individuals believed to have stroke to a primary stroke center, in rural and urban settings, based on time from symptom recognition to treatment, probability of receiving treatment within 3 hours of stroke onset, and probability of overcrowding. We use Indiana as an example.

METHODS

We used discrete-event simulation to estimate outcomes for 2 scenarios: stroke system of care with enabling technology (mobile stroke unit, stroke team expansion) and stroke system of care with no enabling technology, as compared with the status quo. We considered patient flow from symptom recognition to treatment. Patient locations and stroke events were generated for the 92 Indiana counties in Indiana, subdivided into 1009 locations. We considered time from emergency medical service (EMS) arrival at onset to treatment, probability of tissue plasminogen activator administered within 3 h of onset, and percentage of patients admitted beyond the occupancy level at the comprehensive stroke center.

RESULTS

Results varied by urbanicity. Under no enabling technology, having a stroke system of care improved outcomes for individuals in urban and suburban settings. However, in rural settings, the implementation of stroke system of care guidelines decreased the average rate of treatment within 3 h of stroke onset and increased the EMS arrival to treatment times compared with sending the individual to the closest provider. Enabling technologies improved outcomes regardless of setting.

DISCUSSION

Geographic disparities tend to increase the number of transfers, decrease the rate of treatment within 3 h of onset, and increase transit time. This could be overcome through federal and state initiatives to reduce quality gaps in stroke care in rural settings and promote care with dedicated stroke wards.

Current Practice of Neurosurgical Teleconsultation in Germany

OBJECTIVE

 As neurosurgery is a demanding specialty with services in larger medical centers only, consultation over larger distances plays an important role in health care. In times of digitalization, teleconsultation for medical images and cases plays an increasing role in neurosurgical services. However, no standards and demands have been established for its execution in the subfield of neurosurgery, so far. Therefore, as a first step, we performed a survey about the current state of teleconsultation in neurosurgery in Germany.

METHODS

 A standardized questionnaire consisting of 20 items was used to investigate the frequency of use and the operating conditions of teleconsultation in the field of neurosurgery. The survey was performed during the annual national German Society of Neurosurgery conference in 2017. Participation in the written survey was on voluntary and anonymous basis.

RESULTS

 In total, 296 individuals took part in the survey (140 specialists in neurosurgery, 77 residents). Among them, 71% were male and 121 worked at a university medical center. In total, 87.5% of all participants indicated that teleconsultation was used in their institutions (n = 113 in university medical centers and n = 76 in hospitals), and a vast majority stated to have had personal experience with it (88.6% of specialists, 85.5% of residents). The most frequent initial request for a consultation was done by phone call (80.3%). Images or data were then primarily transmitted via an electronic system (77.3%), followed by transmissions via CD or by post. The reply to a consultation was also mainly done by phone call (91.3%), followed by fax, or by e-mail. No standard protocol was followed by 78.6% of the respondents, and they stated not to know about the statutory and legal rules. However, it was stated that the protection of patient data was not endangered by using teleconsultation. The usefulness of teleconsultation and its future relevance were rated highly by the participants. The risk of misinterpretation of image data, especially without having direct access to other patient data, seemed to be a critical and unequivocal challenge.

CONCLUSION

 The results of the survey demonstrate that teleconsultation for medical images and cases is a frequently used and well-accepted tool in neurosurgical health care. However, a standardized neurosurgical procedure is still lacking and the statutory rules for this field of digital medicine are generally not known in our community. Potential misinterpretation and resulting misjudgment seem to be realistic drawbacks. Thus, we see a necessity for elaboration of guidelines for teleconsultation in neurosurgery on national and European basis.

Coronavirus Disease 2019 (COVID-19) and Neurosurgery: Literature and Neurosurgical Societies Recommendations Update

BACKGROUND

Since January 2020, when the pathogen causing the coronavirus disease was identified in humans, the literature on coronavirus disease 2019 (COVID-19) has grown exponentially to more than 4000 publications. There is the need to provide an update for each single medical discipline, including neurosurgery, to be used by single professionals or to be distributed through the neurosurgical community and to be used by governments in designing new scenario of care.

METHODS

A review of the MEDLINE database was performed on April 13, 2020. Search terms included "COVID-19," "neurosurgery," and "surgery." A review of documents published on the webpage of the WFNS (World Federation of Neurosurgical Societies) and of the 5 continental associations of neurosurgical societies, AANS (American Association of Neurological Surgeons), AASNS (Asian Australasian Society of Neurological Surgeons), CAANS (Continental Association of African Neurosurgical Societies), EANS (European Association of Neurosurgical Societies), and FLANC (Latin American Federation of Neurosurgical Societies), representing the 119 national neurosurgical societies around the world, was performed.

RESULTS

The literature search yielded 38 results that were manually reviewed. Fourteen manuscripts were considered eligible. They described suggestions and considerations to optimize care of neurosurgical patients, editorials on operational models, perspectives from neurosurgical departments, letters to the editor describing experiences on how to help medical staff to be prepared in advance for pandemic situations, and descriptions of regional or departmental models and/or organizational schemes. The webpages of the searched societies reported a total of 57 documents.

CONCLUSIONS

The neurosurgical scientific community has promptly reacted to the COVID-19 outbreak by producing a growing number of documents that could serve as guidance for neurosurgeons all over the world. Neurosurgical societies will represent the key institutions for guiding the neurosurgical community to overcome the COVID-19 crisis.

The Impact of Interhospital Transfers on Surgical Quality Metrics for Academic Medical Centers

The emergence of pay-for-performance systems pose a risk to an academic medical center's (AMC) mission to provide care for interhospital surgical transfer patients. This study examines quality metrics and resource consumption for a sample of these patients from the University Health System Consortium (UHC) and our Department of Surgery (DOS). Standard benchmarks, including mortality rate, length of stay (LOS), and cost, were used to evaluate the impact of inter-hospital surgical transfers versus direct admission (DA) patients from January 2010 to December 2012. For 1,423,893 patients, the case mix index for transfer patients was 38 per cent (UHC) and 21 per cent (DOS) greater than DA patients. Mortality rates were 5.70 per cent (UHC) and 6.93 per cent (DOS) in transferred patients compared with 1.79 per cent (UHC) and 2.93 per cent (DOS) for DA patients. Mean LOS for DA patients was 4 days shorter. Mean total costs for transferred patients were greater $13,613 (UHC) and $13,356 (DOS). Transfer patients have poorer outcomes and consume more resources than DA patients. Early recognition and transfer of complex surgical patients may improve patient rescue and decrease resource consumption. Surgeons at AMCs and in the community should develop collaborative programs that permit collective assessment and decision-making for complicated surgical patients.

Natura non facit saltus: a phase 2 proposal to manage brain tumors cases from the Neuro-oncology section of the Italian Society of Neurosurgery (SINch®)

The Coronavirus (COVID-19) pandemic has fast spread throughout the world in more than 200 countries, resulting in the need for a de-prioritization of elective medical care to face the demands of the global health crisis. Although the acute and catastrophic phase of the pandemic seems to have been left behind, it is also clear that the virus will not disappear soon, and we must live with it for a period of unpredictable length, the COVID-19 era. In this setting, a common coordinated approach to treat patients harboring brain tumors is urgently required to guarantee the best updated oncological care and to reduce the risk of viral infection during hospitalization. The study group on Neuro-oncology of Italian Society of Neurosurgery, SINCh gathered pieces of evidence and data and would like to suggest a practice protocol of care for neurosurgical oncologic procedures in the COVID-19 era. The present document aimed at summarizing current evidence and expert opinions to help neurosurgeons in taking decisions on their patients harboring different brain tumors.

Potentially avoidable inter-facility transfer from Veterans Health Administration emergency departments: A cohort study

BACKGROUND

Inter-facility transfer is an important strategy for improving access to specialized health services, but transfers are complicated by over-triage, under-triage, travel burdens, and costs. The purpose of this study is to describe ED-based inter-facility transfer practices within the Veterans Health Administration (VHA) and to estimate the proportion of potentially avoidable transfers.

METHODS

This observational cohort study included all patients treated in VHA EDs between 2012 and 2014 who were transferred to another VHA hospital. Potentially avoidable transfers were defined as patients who were either discharged from the receiving ED or admitted to the receiving hospital for ≤1 day without having an invasive procedure performed. We conducted facility- and diagnosis-level analyses to identify subgroups of patients for whom potentially avoidable transfers had increased prevalence.

RESULTS

Of 6,173,189 ED visits during the 3-year study period, 18,852 (0.3%) were transferred from one VHA ED to another VHA facility. Rural residents were transferred three times as often as urban residents (0.6% vs. 0.2%, p < 0.001), and 22.8% of all VHA-to-VHA transfers were potentially avoidable transfers. The 3 disease categories most commonly associated with inter-facility transfer were mental health (34%), cardiac (12%), and digestive diagnoses (9%).

CONCLUSIONS

VHA inter-facility transfer is commonly performed for mental health and cardiac evaluation, particularly for patients in rural settings. The proportion that are potentially avoidable is small. Future work should focus on improving capabilities to provide specialty evaluation locally for these conditions, possibly using telehealth solutions.

The Current State of Rural Neurosurgical Practice: An International Perspective

Introduction:

Rural and low-resource areas have diminished capacity to care for neurosurgical patients due to lack of infrastructure, healthcare investment, and training programs. This review summarizes the range of rural neurosurgical procedures, novel mechanisms for delivering care, rapid training programs, and outcome differences across international rural neurosurgical practice.

Methods:

A comprehensive literature search was performed for English language manuscripts with keywords “rural” and “neurosurgery” using the National Library of Medicine PubMed database (01/1971–06/2017). Twenty-four articles focusing on rural non-neurosurgical practice were included.

Results:

Time to care and/or surgery and shortage of trained personnel remain the strongest risk factors for mortality and poor outcome. Telemedicine consults to regional centers with neurosurgery housestaff have potential for increased timeliness of diagnosis/triage, improved time to surgery, and reductions in unnecessary transfers in remote areas. Mobile neurosurgery teams have been deployed with success in nations with large transport distances precluding initial transfers. Common neurosurgical procedures involve trauma mechanisms; accordingly, training programs for nonneurosurgery medical personnel on basic assessment and operative techniques have been successful in resource-deficient settings where neurosurgeons are unavailable.

Conclusions:

Protracted transport times, lack of resources/training, and difficulty retaining specialists are barriers to successful outcomes. Advances in telemedicine, mobile neurosurgery, and training programs for urgent operative techniques have been implemented efficaciously. Development of guidelines for paired partnerships between rural centers and academic hospitals, supplying surplus technology to rural areas, and rapid training of qualified local surgical personnel can create sustainable feed-forward programs for trainees and infrastructural solutions to address challenges in rural neurosurgery.

Medical photography with a mobile phone: useful techniques, and what neurosurgeons need to know about HIPAA compliance

Medical photographs are commonly employed to enhance education, research, and patient care throughout the neurosurgical discipline. Current mobile phone camera technology enables surgeons to quickly capture, document, and share a patient scenario with colleagues. Research demonstrates that patients generally view clinical photography favorably, and the practice has become an integral part of healthcare. Neurosurgeons in satellite locations often rely on residents to send photographs of diagnostic imaging studies, neurological examination findings, and postoperative wounds. Images are also frequently obtained for research purposes, teaching and learning operative techniques, lectures and presentations, comparing preoperative and postoperative outcomes, and patient education. However, image quality and technique are highly variable. Capturing and sharing photographs must be accompanied by an awareness of the legal ramifications of the Health Insurance Portability and Accountability Act (HIPAA). HIPAA compliance is straightforward when one is empowered with the knowledge of what constitutes a patient identifier in a photograph. Little has been published to describe means of improving the accuracy and educational value of medical photographs in neurosurgery. Therefore, in this paper, the authors present a brief discussion regarding four easily implemented photography skills every surgeon who uses his or her mobile phone for patient care should know: 1) provide context, 2) use appropriate lighting, 3) use appropriate dimensionality, and 4) manage distracting elements. Details of the HIPAA-related components of mobile phone photographs and patient-protected health information are also included.

Interhospital Transfer of Neurosurgical Patients: Implications of Timing on Hospital Course and Clinical Outcomes

BACKGROUND

Interhospital transfer of neurosurgical patients is common; however, little is known about the impact of transfer parameters on clinical outcomes. Lower survival rates have been reported for patients admitted at night and on weekends in other specialties. Whether time or day of admission affects neurosurgical patient outcomes, specifically those transferred from other facilities, is unknown.

OBJECTIVE

To examine the impact of the timing of interhospital transfer on the hospital course and clinical outcomes of neurosurgical patients.

METHODS

All consecutive admissions of patients transferred to our adult neurosurgical service were retrospectively analyzed for a 1-year study period using data from a central transfer database and the electronic health record.

RESULTS

Patients arrived more often at night (70.8%) despite an even distribution of transfer requests. The lack of transfer imaging did not affect length of stay, intervention times, or patient outcomes. Daytime arrivals had shorter total transfer time, but longer intenstive care unit and overall length of stay (8.7 and 11.6 days, respectively), worse modified Rankin Scale scores, lower rates of functional independence, and almost twice the mortality rate. Weekend admissions had significantly worse modified Rankin Scale scores and lower rates of functional independence.

CONCLUSIONS

The timing of transfer arrivals, both by hour or day of the week, is correlated with the time to intervention, hospital course, and overall patient outcomes. Patients admitted during the weekend suffered worse functional outcomes and a trend towards increased mortality. While transfer logistics clearly impact patient outcomes, further work is needed to understand these complex relationships.

Analysis of three surgical treatments for spontaneous supratentorial intracerebral hemorrhage

This retrospective study aimed to evaluate the effectiveness and safety of 3 surgical procedures for Spontaneous Supratentorial Intracerebral Hemorrhage (SICH).A total of 63 patients with SICH were randomized into 3 groups. Group A (n = 21) underwent craniotomy surgery, group B (n = 22) underwent burr hole, urokinase infusion and catheter drainage, and group C (n = 20) underwent neuroendoscopic surgery. The hematoma evacuation rate of the operation was analyzed by 3D Slice software and the average surgery time, visualization during operation, decompressive effect, mortality, Glasgow Coma Scale (GCS) improvement, complications include rebleeding, pneumonia, intracranial infection were also compared among 3 groups.All procedures were successfully completed and the hematoma evacuation rate was significant differences among 3 groups which were 79.8%, 43.1%, 89.3% respectively (P < .01), and group C was the highest group. Group B was smallest traumatic one and shared the shortest operation time, but for the lack of hemostasis, it also the highest rebleeding group (P = .03). Although there were different in complications, but there was no significant in pneumonia, intracranial infection, GCS improvement and mortality rate.All these 3 methods had its own advantages and shortcomings, and every approach had its indications for SICH. Although for neuroendoscopic technical's minimal invasive, direct vision, effectively hematoma evacuation rate, and the relatively optimistic result, it might be a more promising approach for SICH.

Management of intracerebral hemorrhage

Intracerebral hemorrhage (ICH) is a potentially devastating neurologic injury representing 10-15% of stroke cases in the USA each year. Numerous risk factors, including age, hypertension, male gender, coagulopathy, genetic susceptibility, and ethnic descent, have been identified. Timely identification, workup, and management of this condition remain a challenge for clinicians as numerous factors can present obstacles to achieving good functional outcomes. Several large clinical trials have been conducted over the prior decade regarding medical and surgical interventions. However, no specific treatment has shown a major impact on clinical outcome. Current management guidelines do exist based on medical evidence and consensus and these provide a framework for care. While management of hypertension and coagulopathy are generally considered basic tenets of ICH management, a variety of measures for surgical hematoma evacuation, intracranial pressure control, and intraventricular hemorrhage can be further pursued in the emergent setting for selected patients. The complexity of management in parenchymal cerebral hemorrhage remains challenging and offers many areas for further investigation. A systematic approach to the background, pathology, and early management of spontaneous parenchymal hemorrhage is provided.

The Empirical Foundations of Teleradiology and Related Applications: A Review of the Evidence

INTRODUCTION

Radiology was founded on a technological discovery by Wilhelm Roentgen in 1895. Teleradiology also had its roots in technology dating back to 1947 with the successful transmission of radiographic images through telephone lines. Diagnostic radiology has become the eye of medicine in terms of diagnosing and treating injury and disease. This article documents the empirical foundations of teleradiology.

METHODS

A selective review of the credible literature during the past decade (2005-2015) was conducted, using robust research design and adequate sample size as criteria for inclusion.

FINDINGS

The evidence regarding feasibility of teleradiology and related information technology applications has been well documented for several decades. The majority of studies focused on intermediate outcomes, as indicated by comparability between teleradiology and conventional radiology. A consistent trend of concordance between the two modalities was observed in terms of diagnostic accuracy and reliability. Additional benefits include reductions in patient transfer, rehospitalization, and length of stay.

Fully Endoscopic Freehand Evacuation of Spontaneous Supratentorial Intraparenchymal Hemorrhage

OBJECTIVE

A modification of other reported endoscopic techniques for intracerebral clot evacuation is described and illustrated.

METHODS

From January 2014 to December 2014, we operated on 6 patients harboring a spontaneous supratentorial intracerebral hemorrhage using a fully endoscopic freehand technique. Clinical chart and surgical videos were analyzed. Volumetric evaluation of the clot preoperatively and the residual hematoma postoperatively was performed. Clinical outcome was measured using the modified Rankin Scale and Glasgow Outcome Scale.

RESULTS

The mean operative time was 96 minutes (range, 72-125 minutes). Clot evacuation was >90% in all patients. No patient experienced rebleeding after surgery. Two patients died. The Glasgow Outcome Scale score at 6 months was 4 in 2 patients, 3 in 2 patients, and 1 (death) in 2 patients. The modified Rankin Scale score at 6 months was 6 (death) in 2 patients, 4 in 2 patients, 3 in 1 patient and 2 in 1 patient.

CONCLUSIONS

The proposed minimally invasive technique allows a good rate of hematoma evacuation and intraoperative bleeding control. Further studies in large series are needed to confirm the role of this freehand endoscopic technique.

Description of a novel telemedicine-enabled comprehensive system of care: drip and ship plus drip and keep within a system of stroke care delivery

United States (US) and worldwide telestroke programs frequently focus only on emergency room hyper-acute stroke management. This article describes a comprehensive, telemedicine-enabled, stroke care delivery system that combines “drip and ship” and “drip and keep” models with a comprehensive stroke center primary hub at Ochsner Medical Center in New Orleans, advanced stroke-capable regional hubs, and geographically-aligned, “stroke-ready” spokes. The primary hub provides vascular neurology expertise via telemedicine and monitors care for patients remaining at regional hubs and spokes using a multidisciplinary team approach. By 2014, primary hub telestroke consults grew to ≈1000/year with 16 min average door to consult initiation and 20 min to completion, and 29% of ischemic stroke patients received recombinant tissue-type plasminogen activator (rtPA), increasing 275%. Most patients remained in hospitals close to home, but neurointensive care and interventional procedures were common reasons for primary hub transfer. Given the time sensitivity and expert consultation needed for complex acute stroke care delivery paradigms, telestroke programs are effective for fulfilling unmet care needs. Combining drip and ship and drip and keep management allows more patients to stay “local,” limiting primary hub transfer unless more advanced services are required. Post admission telestroke management at spokes increases personnel efficiency and can positively impact stroke outcomes.

Intracranial hemorrhage: frequency, location, and risk factors identified in a TeleStroke network

Intracranial hemorrhages are associated with high rates of disability and mortality. Telemedicine in general provides clinical healthcare at a distance by using videotelephony and teleradiology and is used particularly in acute stroke care medicine (TeleStroke). TeleStroke considerably improves quality of stroke care (for instance, by increasing thrombolysis) and may be valuable for the management of intracranial hemorrhages in rural hospitals and hospitals lacking neurosurgical departments, given that surgical/interventional therapy is only recommended for a subgroup of patients. The aim of this study was to analyze the frequency, anatomical locations of intracranial hemorrhage, risk factors, and the proportion of patients transferred to specialized hospitals. We evaluated teleconsultations conducted between 2008 and 2010 in a large cohort of patients consecutively enrolled in the Telemedical Project for Integrated Stroke Care (TEMPiS) network. In cases in which intracranial hemorrhage was detected, all images were re-examined and analyzed with a focus on frequency, location, risk factors, and further management. Overall, 6187 patients presented with stroke-like symptoms. Intracranial hemorrhages were identified in 631 patients (10.2%). Of these, intracerebral hemorrhages were found in 423 cases (67.0%), including 174 (41.1%) in atypical locations and 227 (53.7%) in typical sites among other locations. After 14 days of hospitalization in community facilities, the mortality rate in patients with intracranial hemorrhages was 15.1% (95/631). Two hundred and twenty-three patients (35.3%) were transferred to neurological/neurosurgical hospitals for diagnostic workup or additional treatment. Community hospitals are confronted with patients with intracranial hemorrhage, whose management requires specific neurosurgical and hematological expertise with respect to hemorrhage subtype and clinical presentation. TeleStroke networks help select patients who need advanced neurological and/or neurosurgical care. The relatively low proportion of interhospital transfers shown in this study reflects a differentiated decision process on the basis of both guidelines and standard operating procedures.

Guidelines for the Management of Spontaneous Intracerebral Hemorrhage: A Guideline for Healthcare Professionals From the American Heart Association/American Stroke Association

PURPOSE

The aim of this guideline is to present current and comprehensive recommendations for the diagnosis and treatment of spontaneous intracerebral hemorrhage.

METHODS

A formal literature search of PubMed was performed through the end of August 2013. The writing committee met by teleconference to discuss narrative text and recommendations. Recommendations follow the American Heart Association/American Stroke Association methods of classifying the level of certainty of the treatment effect and the class of evidence. Prerelease review of the draft guideline was performed by 6 expert peer reviewers and by the members of the Stroke Council Scientific Oversight Committee and Stroke Council Leadership Committee.

RESULTS

Evidence-based guidelines are presented for the care of patients with acute intracerebral hemorrhage. Topics focused on diagnosis, management of coagulopathy and blood pressure, prevention and control of secondary brain injury and intracranial pressure, the role of surgery, outcome prediction, rehabilitation, secondary prevention, and future considerations. Results of new phase 3 trials were incorporated.

CONCLUSIONS

Intracerebral hemorrhage remains a serious condition for which early aggressive care is warranted. These guidelines provide a framework for goal-directed treatment of the patient with intracerebral hemorrhage.

Sinomenine inhibits microglia activation and attenuates brain injury in intracerebral hemorrhage

Intracerebral hemorrhage (ICH) causes morbidity and mortality and commonly follows the reperfusion after an ischemic event. Microglial activation mediated cytokine and protease secretion contributes to brain injury in ICH. Previous studies have shown that sinomenine possesses potent immunoregulatory properties. However, little is known about its exact role in ICH. In the present study, to investigate the effect of sinomenine on microglial cells inflammation, we treated ICH-challenged BV2 microglial cells with sinomenine in vitro, and explored its neuroprotection role in intracerebral hemorrhage in vivo. Changes in inflammatory cytokines, such as TNF-α, IL-1β and IL-6, reactive oxygen species (ROS) and NF-κB activation NF-κB were observed. In addition, the neurological deficit and cerebral water content of ICH mice were studied. The results demonstrated that sinomenine could inhibit the release of these cytokines and attenuate ROS production in a dose-dependent manner, and reduce NF-κB activation. Furthermore, sinomenine markedly inhibited cerebral water content and neurological deficit. In conclusion, our findings suggest that sinomenine played the protective effects through inhibition of microglial inflammation, and the findings also provided a novel therapy to treat ICH induced brain injury.

The use of telemedicine in the management of acute stroke

Cerebrovascular disease, including acute ischemic stroke, remains a major public health problem in the US and throughout the world. There has been a concerted effort to apply evidence-based practices to stroke care to improve primary and secondary prevention as well as poststroke outcomes. Geography and workforce shortages contribute to a disparity in stroke care, however, among the substantial proportion of the US population that lives outside the reach of an acute stroke–ready hospital or a primary or comprehensive stroke center. In an attempt to combat the rural-to-urban disparity and expand the availability of best stroke practices, Levine and Gorman proposed the development of telemedical outreach for acute stroke evaluation and management, which they called “telestroke.” Since then, the practice of telestroke has been found to have a high interrater agreement with a bedside assessment of the National Institutes of Health Stroke Scale score, to enhance correct thrombolysis decision making as compared with telephone-only consultation, and to be cost-effective. In light of these findings and the perception of benefit by acute stroke providers and patients, there has been growing interest in and a rapid expansion of telestroke networks in the US and internationally. There are legal and financial barriers to more widespread use of telemedicine in general, including telestroke. Further research is needed to understand the potential merits of telestroke infrastructure for the many phases of stroke care including poststroke hospitalization, prevention of complications, enhancing secondary prevention, and education of patients and providers.

Digital images taken with a mobile phone can assist in the triage of neurosurgical patients to a level 1 trauma centre

We investigated whether head CT images captured using a mobile phone would be of sufficient quality for neurosurgeons at a level 1 trauma centre to make decisions about whether to transfer patients from referring hospitals. All patients who had been transferred from outside facilities with reported intracranial pathology during 2008 were identified. Two emergency medicine physicians selected 1-3 images from the hospital archive that best represented the pathology described by the radiologist and the medical record. The images were photographed in a darkened room using a smart phone. The mobile phone images and clinical history were reviewed by two neurosurgeons independently. The neurosurgeons rated the adequacy and quality of the images, and indicated whether the images would have changed their transfer decision. Based on clinical data alone, neurosurgeon A would have transferred 64 (73%) patients and neurosurgeon B 39 (44%). After images were provided, A would have transferred 67 (76%) and B would have transferred 49 (56%). The availability of the images significantly altered the transfer decision by A in 25 cases (28%) (P = 0.024) and by B in 28 cases (32%) (P < 0.001). The level of agreement between the two neurosurgeons significantly increased from 53% (kappa = 0.11) to 75% (kappa = 0.47) (P < 0.001). Mobile-phone images of CT scans appear to provide adequate images for triaging patients and helping with transfer decisions of neurosurgical cases.
