Endovascular stenting for cerebral venous sinus stenosis secondary to meningioma invasion.

INTRODUCTION: Symptomatic intracranial hypertension (IH) due to venous outflow obstruction secondary to dural venous sinus (DVS) tumoral invasion affects up to 3% of intracranial meningioma patients. The literature regarding endovascular therapies of such patients is limited to a few case reports and a recent single-centre case series. PURPOSE: We describe our single-centre experience of endovascular therapy in patients with clinically symptomatic IH secondary to DVS meningioma invasion. METHODS: We performed a retrospective review of clinical and radiological data of all patients with refractory IH and meningiomas invading the DVS who were referred for possible DVS venoplasty and stenting. Seven endovascular procedures in six female patients were done. Presumed secondarily induced lateral transverse sinus stenosis was also stented in four patients as part of the primary intervention. RESULTS: All patients experienced complete symptomatic resolution at 6-month follow-up. Five patients had no symptom recurrence over a mean follow-up period of 3.5 years. One patient with multiple meningiomas developed recurrent IH 2 years following stenting secondary to in-stent tumour re-invasion. This was re-stented with consequent 6 months post-retreatment symptomatic relief at the time of writing. No procedure-related complications occurred. CONCLUSION: In the setting of DVS stenosis secondary to meningioma invasion, endovascular therapy is a safe and successful therapeutic option with promising mid-term results. The procedure should be considered in cases where complete surgical tumour resection is unlikely or carries a significant risk. If present, secondarily induced stenoses at the lateral ends of the transverse sinuses should also be considered for treatment.

Neurosurgery activity levels in the United Kingdom and republic of Ireland during the first wave of the covid-19 pandemic - a retrospective cross-sectional cohort study.

The impact of Covid-19 on surgical patients worldwide has been substantial. In the United Kingdom (UK) and the Republic of Ireland (RoI), the first wave of the pandemic occurred in March 2020. The aims of this study were to: (1) evaluate the volume of neurosurgical operative activity levels, Covid-19 infection rate and mortality rate in April 2020 with a retrospective cross-sectional cohort study conducted across 16 UK and RoI neurosurgical centres, and (2) compare patient outcomes in a single institution in April-June 2020 with a comparative cohort in 2019. Across the UK and RoI, 818 patients were included. There were 594 emergency and 224 elective operations. The incidence rate of Covid-19 infection was 2.6% (21/818). The overall mortality rate in patients with a Covid-19 infection was 28.6% (6/21). In the single centre cohort analysis, an overall reduction in neurosurgical operative activity by 65% was observed between 2020 (n = 304) and 2019 (n = 868). The current and future impact on UK neurosurgical operative activity has implications for service delivery and neurosurgical training.

Predictors of Multiple Emergency Department Utilization Among Frequent Emergency Department Users in 3 States.

BACKGROUND: Research on frequent emergency department (ED) use shows that a subgroup of patients visits multiple EDs. This study characterizes these individuals. OBJECTIVE: The objective of this study was to determine how many frequent ED users seek care at multiple EDs and to identify sociodemographic, clinical, and contextual factors associated with such behavior. RESEARCH DESIGN: We used the 2011-2014 Healthcare Cost and Utilization Project State Emergency Department Databases data on all outpatient ED visits in New York, Massachusetts, and Florida. We studied all adult ED users with ≥5 visits in a year and defined multisite use as visits to ≥3 different sites. We estimated predictors of multisite use with multivariate logistic regressions. RESULTS: Across all 3 states, 1,033,626 frequent users accounted for 7,613,077 ED visits. Of frequent users, 25% were multisite users, accounting for 30% of the visits studied. Frequent users with at least 1 visit for mental health or substance use-related diagnosis were more likely to use multiple sites. Uninsured frequent users and those with public insurance were associated with less use of multiple EDs than those with private coverage while lacking consistent coverage by the same insurance within each year were associated with using multiple sites. CONCLUSIONS: Health policy interventions to reduce duplicative or unnecessary ED use should apply a population health perspective and engage multiple hospitals. Community-level preventive approaches and a stronger infrastructure for mental health and substance use are essential to mitigate multisite ED use.

Local alkylating chemotherapy applied immediately after 5-ALA guided resection of glioblastoma does not provide additional benefit.

Grade IV glioma is the most common and aggressive primary brain tumour. Gross total resection with 5-aminolevulinic acid (5-ALA) guided surgery combined with local chemotherapy (carmustine wafers) is an attractive treatment strategy in these patients. No previous studies have examined the benefit carmustine wafers in a treatment programme of 5-ALA guided resection followed by a temozolomide-based chemoradiotherapy protocol. The objective of this study was to examine the benefit of carmustine wafers on survival in patients undergoing 5-ALA guided resection. A retrospective cohort study of 260 patients who underwent 5-ALA resection of confirmed WHO 2007 Grade IV glioma between July 2009 and December 2014. Survival curves were calculated using the Kaplan-Meier method from surgery. The log-rank test was used to compare survival curves between groups. Cox regression was performed to identify variables predicting survival. A propensity score matched analysis was used to compare survival between patients who did and did not receive carmustine wafers while controlling for baseline characteristics. Propensity matched analysis showed no significant survival benefit of insertion of carmustine wafers over 5-ALA resection alone (HR 0.97 [0.68-1.26], p = 0.836). There was a trend to higher incidence of wound infection in those who received carmustine wafers (15.4 vs. 7.1%, p = 0.064). The Cox regression analysis showed that intraoperative residual fluorescent tumour and residual enhancing tumour on post-operative MRI were significantly predictive of reduced survival. Carmustine wafers have no added benefit following 5-ALA guided resection. Residual fluorescence and residual enhancing disease following resection have a negative impact on survival.

Assembled Products: The Key to More Effective Competition And Antitrust Oversight in Health Care.

This Article argues that recent calls for antitrust enforcement to protect health insurers from hospital and physician consolidation are incomplete. The principal obstacle to effective competition in health care is not that one or the other party has too much bargaining power, but that they have been buying and selling the wrong things. Vigorous antitrust enforcement will benefit health care consumers only if it accounts for the competitive distortions caused by the sector's long history of government regulation. Because of regulation, what pass for products in health care are typically small process steps and isolated components that can be assigned a billing code, even if they do little to help patients. Instead of further entrenching weakly competitive parties engaged in artificial commerce, antitrust enforcers and regulators should work together to promote the sale of fully assembled products and services that can be warranted to consumers for performance and safety. As better products emerge through innovation and market entry, competition may finally succeed at lowering medical costs, increasing access to treatment, and improving quality of care.

Why MLP Legal Care Should Be Financed as Health Care.

Medical-legal partnership (MLP) integrates the unique expertise of lawyers into collaborative clinical environments. MLP teams meet the needs of individual patients while also detecting structural problems at the root of health inequities and advancing solutions at the institutional, community, and system levels. Yet MLPs today operate in limited settings and survive on scant budgets. Expanding their impact requires secure funding. Financing MLPs as health care can do the following: (1) help address inequity at the point of care; (2) enable expert diagnosis and treatment of nonmedical drivers of health; (3) enhance team-based practice in health care organizations; (4) offer another way for clinicians to participate in advocacy; and (5) bolster a broader movement to increase access to justice.

The clinical and functional outcomes of ultrasound-guided vs landmark-guided injections for adults with shoulder pathology--a systematic review and meta-analysis.

OBJECTIVE: To compare the clinical and functional outcomes of US-guided (USG) vs landmark-guided (LMG) injection for the treatment of adults with shoulder pathology. METHOD: MEDLINE, AMED and Embase in addition to unpublished literature databases were searched from 1950 to August 2011. Studies were included if they were randomized or non-randomized controlled trials comparing USG vs LSG injections for the treatment of adults with shoulder pathology. Two reviewers independently performed data extraction and appraisal of the studies. Meta-analyses were performed where possible and when inappropriate a narrative review of the data was presented. RESULTS: Six papers including 307 patients were reviewed; 142 received LMG injections and 165 received USG injections. There was a statistically significant difference in favour of USG for pain at 6 weeks (standardized mean difference 1.03; 95% CI 0.12, 1.93; P = 0.03). There was no statistically significant difference between the injection methods with respect to shoulder function (standardized mean difference 0.33; 95% CI -0.59, 1.25; P = 0.48). There was a significant difference between interventions for shoulder abduction at 6 weeks in favour of the USG method (mean difference 2.81; 95% CI 0.67, 4.95; P = 0.01). No other movements showed a statistically significant difference. CONCLUSION: There is a statistically significant difference in pain and abduction between LMG and USG steroid injections for adults with shoulder pathology. However, these differences are small and may not represent clinically useful differences. The current evidence base is limited by a number of important methodological weaknesses, which should be considered when interpreting these findings. The cost-effectiveness of the intervention should be considered in the design of future studies.

Swimming Together Upstream: How to Align MLP Services with U.S. Healthcare Delivery.

Medical-legal partnership (MLP) embeds attorneys and paralegals into care delivery to help clinicians address root causes of health inequities. Notwithstanding decades of favorable outcomes, MLP is not as well-known as might be expected. In this essay, the authors explore ways in which strategic alignment of legal services with healthcare services in terms of professionalism, information collection and sharing, and financing might help the MLP movement become a more widespread, sustainable model for holistic care delivery.

Heart rate variability during high-speed treadmill exercise and recovery in Thoroughbred racehorses presented for poor performance.

BACKGROUND: Heart rate variability (HRV) analysis measures the inter-beat interval variation of successive cardiac cycles. Measurement of these indices has been used to assess cardiac autonomic modulation and for arrhythmia identification in exercising horses. OBJECTIVES: To report HRV indices during submaximal exercise, strenuous exercise and recovery, and explore relationships with clinical conditions (arrhythmias, lameness, equine gastric ulcer syndrome [EGUS], lower airway inflammation and upper respiratory tract obstructions [URTOs]) in Thoroughbred racehorses. STUDY DESIGN: Retrospective, observational cross-sectional study. METHODS: One hundred and eighty Thoroughbred horses underwent a treadmill exercise test with simultaneous electrocardiographic recording. Time-domain HRV indices (standard deviation of the R-R interval [SDRR]; root mean square of successive differences [RMSSD]) were derived for submaximal and strenuous exercise and recovery segments. Clinical conditions (arrhythmia [during each phase of exercise], lameness, EGUS, lower airway inflammation and URTO) were assigned to binary categories for statistical analysis. Relationships between selected HRV indices and the clinical conditions were explored using linear regression models. RESULTS: During submaximal exercise, lameness was associated with decreased logRMSSD (B = -0.19 95% confidence interval [CI] -0.31 to -0.06, p = 0.006) and arrhythmia was associated with increased logRMSSD (B = 0.31 95% CI 0.01-0.608, p = 0.04). During strenuous exercise, arrhythmia was associated with increased HRV indices (logSDRR B = 0.51 95% CI 0.40-0.62, p < 0.001; RMSSD B = 0.60 95% CI 0.49-0.72, p < 0.001). During recovery, arrhythmia was associated with increased HRV indices (logSDRR B = 0.51 95% CI 0.40-0.62, p < 0.001, logRMSSD B = 0.60 95% CI 0.49-0.72, p < 0.001). MAIN LIMITATIONS: The main limitations of this retrospective study were that not every horse had the full range of clinical testing, therefore some horses may have had undetected abnormalities. CONCLUSIONS: The presence of arrhythmia increased HRV in both phases of exercise and recovery. Lameness decreased HRV during submaximal exercise.

CovidNeuroOnc: A UK multicenter, prospective cohort study of the impact of the COVID-19 pandemic on the neuro-oncology service.

BACKGROUND: The COVID-19 pandemic has profoundly affected cancer services. Our objective was to determine the effect of the COVID-19 pandemic on decision making and the resulting outcomes for patients with newly diagnosed or recurrent intracranial tumors. METHODS: We performed a multicenter prospective study of all adult patients discussed in weekly neuro-oncology and skull base multidisciplinary team meetings who had a newly diagnosed or recurrent intracranial (excluding pituitary) tumor between 01 April and 31 May 2020. All patients had at least 30-day follow-up data. Descriptive statistical reporting was used. RESULTS: There were 1357 referrals for newly diagnosed or recurrent intracranial tumors across 15 neuro-oncology centers. Of centers with all intracranial tumors, a change in initial management was reported in 8.6% of cases (n = 104/1210). Decisions to change the management plan reduced over time from a peak of 19% referrals at the start of the study to 0% by the end of the study period. Changes in management were reported in 16% (n = 75/466) of cases previously recommended for surgery and 28% of cases previously recommended for chemotherapy (n = 20/72). The reported SARS-CoV-2 infection rate was similar in surgical and non-surgical patients (2.6% vs. 2.4%, P > .9). CONCLUSIONS: Disruption to neuro-oncology services in the UK caused by the COVID-19 pandemic was most marked in the first month, affecting all diagnoses. Patients considered for chemotherapy were most affected. In those recommended surgical treatment this was successfully completed. Longer-term outcome data will evaluate oncological treatments received by these patients and overall survival.

Toward a 21st-century health care system: recommendations for health care reform.

The coverage, cost, and quality problems of the U.S. health care system are evident. Sustainable health care reform must go beyond financing expanded access to care to substantially changing the organization and delivery of care. The FRESH-Thinking Project (www.fresh-thinking.org) held a series of workshops during which physicians, health policy experts, health insurance executives, business leaders, hospital administrators, economists, and others who represent diverse perspectives came together. This group agreed that the following 8 recommendations are fundamental to successful reform: 1. Replace the current fee-for-service payment system with a payment system that encourages and rewards innovation in the efficient delivery of quality care. The new payment system should invest in the development of outcome measures to guide payment. 2. Establish a securely funded, independent agency to sponsor and evaluate research on the comparative effectiveness of drugs, devices, and other medical interventions. 3. Simplify and rationalize federal and state laws and regulations to facilitate organizational innovation, support care coordination, and streamline financial and administrative functions. 4. Develop a health information technology infrastructure with national standards of interoperability to promote data exchange. 5. Create a national health database with the participation of all payers, delivery systems, and others who own health care data. Agree on methods to make de-identified information from this database on clinical interventions, patient outcomes, and costs available to researchers. 6. Identify revenue sources, including a cap on the tax exclusion of employer-based health insurance, to subsidize health care coverage with the goal of insuring all Americans. 7. Create state or regional insurance exchanges to pool risk, so that Americans without access to employer-based or other group insurance could obtain a standard benefits package through these exchanges. Employers should also be allowed to participate in these exchanges for their employees' coverage. 8. Create a health coverage board with broad stakeholder representation to determine and periodically update the affordable standard benefit package available through state or regional insurance exchanges.

Interest-based mediation of medical malpractice lawsuits: a route to improved patient safety?

Mediation of medical malpractice lawsuits provides savings for the parties by shortening the litigation process. In theory, information that aids emotional healing and improves patient care can also surface through mediation. The study discussed in this article used structured interviews of participants and mediators in thirty-one mediated malpractice lawsuits involving eleven nonprofit hospitals. The study measured perceptions of the process and mediation's effects on settlement, expenses, apology, satisfaction, and information exchange. Defense lawyers were less likely than plaintiff attorneys to mediate. Both plaintiff and defense attorneys were satisfied with the process, as were plaintiffs, hospital representatives, and insurers. Changes in hospitals' practices or policies to improve patient safety were identified. This study demonstrates that major challenges stand in the way of achieving mediation's full benefits. Absence of physician participation minimizes the chances that mediated discussion of adverse events and medical errors can lead to improved quality of care. Change will require medical leaders, hospital administrators, and malpractice insurers to temper their suspicion of the tort system sufficiently to approach medical errors and adverse events as learning opportunities, and to retain lawyers who embrace mediation as an opportunity to solve problems, show compassion, and improve care.

Following the Money: The ACA's Fiscal-Political Economy and Lessons for Future Health Care Reform.

It is no exaggeration to say that American health policy is frequently subordinated to budgetary policies and procedures. The Affordable Care Act (ACA) was undeniably ambitious, reaching health care services and underlying health as well as health insurance. Yet fiscal politics determined the ACA's design and guided its implementation, as well as sometimes assisting and sometimes constraining efforts to repeal or replace it. In particular, the ACA's vulnerability to litigation has been the price its drafters paid in exchange for fiscal-political acceptability. Future health care reformers should consider whether the nation is well served by perpetuating such an artificial relationship between financial commitments and health returns.

The social construction of disability and the capabilities approach: Implications for nursing.

PROBLEM: Improving the health and well-being of people with disabilities (PWD) should be included https://plato.stanford.edu/cgi-bin/encyclopedia/archinfo.cgi?entry=justice-distributivein any strategies aimed at eliminating health disparities and achieving health equity in the United States. However, practitioners and policymakers often overlook disability when considering health equity. This is problematic because structural injustices including social and environmental barriers frequently worsen health for PWD. A commitment to social justice, however, dictates that everyone should have equitable opportunities to participate in chosen aspects of life to the best of their abilities and desires. METHODS: We use a critical commentary to provide suggestions for the nursing discipline. Specifically, we 1) position the disparities in health and well-being experienced by PWD as matters of equity and social justice, 2) describe Amartya Sen's capabilities approach, and 3) provide suggestions for incorporating tenets of the capabilities approach into nursing practice, research, and policy. CONCLUSION: The capabilities approach can provide a useful framework to guide nursing practice, research, and policy in order to advance social justice for PWD.

Patient safety and the ageing physician: a qualitative study of key stakeholder attitudes and experiences.

BACKGROUND: Unprecedented numbers of physicians are practicing past age 65. Unlike other safety-conscious industries, such as aviation, medicine lacks robust systems to ensure late-career physician (LCP) competence while promoting career longevity. OBJECTIVE: To describe the attitudes of key stakeholders about the oversight of LCPs and principles that might shape policy development. DESIGN: Thematic content analysis of interviews and focus groups. PARTICIPANTS: 40 representatives of stakeholder groups including state medical board leaders, institutional chief medical officers, senior physicians (>65 years old), patient advocates (patients or family members in advocacy roles), nurses and junior physicians. Participants represented a balanced sample from all US regions, surgical and non-surgical specialties, and both academic and non-academic institutions. RESULTS: Stakeholders describe lax professional self-regulation of LCPs and believe this represents an important unsolved challenge. Patient safety and attention to physician well-being emerged as key organising principles for policy development. Stakeholders believe that healthcare institutions rather than state or certifying boards should lead implementation of policies related to LCPs, yet expressed concerns about resistance by physicians and the ability of institutions to address politically complex medical staff challenges. Respondents recommended a coaching and professional development framework, with environmental changes, to maximise safety and career longevity of physicians as they age. CONCLUSIONS: Key stakeholders express a desire for wider adoption of LCP standards, but foresee significant culture change and practical challenges ahead. Participants recommended that institutions lead this work, with support from regulatory stakeholders that endorse standards and create frameworks for policy adoption.
