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.

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.

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.

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.

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.

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.

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.

Trends in Medicare Payment Rates for Noninvasive Cardiac Tests and Association With Testing Location.

Importance: To control spending, the Centers for Medicare & Medicaid Services reduced Medicare fee-for-service (FFS) payments for noninvasive cardiac tests (NCTs) performed in provider-based office settings (ambulatory offices not administratively affiliated with hospitals) starting in 2005. Contemporaneously, payments for hospital-based outpatient testing increased. The association between differential payments by site and test location is unknown. Objectives: To quantify trends in differential Medicare FFS payments for NCTs performed in hospital-based and provider-based settings, determine the association between the hospital-based outpatient testing to provider-based office testing payment ratio and the proportion of hospital-based NCTs, and to examine trends in test location between Medicare FFS and 3 Medicare Advantage health maintenance organizations for which Centers for Medicare & Medicaid Services payments do not depend on testing location. Design, Setting, and Participants: This observational claims-based study used Medicare FFS claims from 1999 to 2015 (5% random sample) and Medicare Advantage claims from 3 large health maintenance organizations (2005-2015) among Medicare FFS beneficiaries aged 65 years or older and a health maintenance organization control group. Statistical analysis was performed from May 1, 2017, to July 15, 2019. Exposures: The weighted mean payment ratio of Medicare FFS hospital-based outpatient testing to provider-based office testing for outpatient NCTs. Main Outcomes and Measures: Proportion of outpatient NCTs performed in the hospital-based setting and Medicare FFS costs. Results: The data included a mean of 1.72 million patient-years annually in Medicare FFS (mean age, 75.2 years; 57.3% female in 2015) and a mean of 142 230 patient-years annually in the managed care control group (mean age, 74.8 years; 56.2% female in 2015). The Medicare payment ratio of FFS hospital-based outpatient testing to provider-based office testing increased from 1.05 in 2005 to 2.32 in 2015. The FFS hospital-based outpatient testing proportion increased from 21.1% in 2008 to 43.2% in 2015 and was correlated with the payment ratio (correlation coefficient with a 1-year lag, 0.767; P < .001). In contrast, the hospital-based outpatient testing proportion for the control group declined from 16.6% in 2008 to 15.2% in 2015 (correlation coefficient, -0.024, P = .95). The estimated extra costs owing to tests shifting to the hospital-based outpatient setting in the Medicare FFS group was $661 million in 2015, including $161 million in patient out-of-pocket costs. Conclusions and Relevance: In settings in which reimbursement depends on test location, increasing hospital-based payments correlated with greater proportions of outpatient NCTs performed in the hospital-based outpatient setting. Site-neutral payments may offer an incentive for testing to be performed in the more efficient location.

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.

Quality improvement of neuro-oncology services: integrating the routine collection of patient-reported, health-related quality-of-life measures.

BACKGROUND: Brain cancer has a strong impact on health-related quality of life (HRQoL), and its evaluation in clinical practice can improve the quality of care provided. The aim of this project was to integrate routine collection of HRQoL information from patients with brain tumor or metastasis in 2 specialized United Kingdom tertiary centers, and to evaluate the implementation process. METHODS: Since October 2016, routine collection of electronic self-reported HRQoL information has been progressively embedded in the participating centers using standard questionnaires. During the first year, the project was implemented, and the process evaluated, through regular cycles of process evaluation followed by an action plan, monitoring of questionnaire completion rates, and assessment of patient views. RESULTS: Main challenges encountered included reluctance to change usual practice and limited resources. Key measures for success included strong leadership of senior staff, involvement of stakeholders in project design and evaluation, and continuous strategic support to professionals. Final project workflow included 6 process steps, 1 decision step, and 4 outputs. Questionnaires were mostly self-completed (75.1%), and completion took 6-9 minutes. Most patients agreed that the questionnaire items were easy to understand (97.0%), important for them (93.0%), and helped them think what they wanted to discuss in their clinical consultation (75.4%). CONCLUSIONS: Integrating HRQoL information as a routine part of clinical assessments has the potential to enhance individually tailored patient care in our institutions. Challenges involved in innovations of this nature can be overcome through a systematic approach involving strong leadership, wide stakeholder engagement, and strategic planning.

Defining unmet clinical need across the pathway of brain tumor care: a patient and carer perspective.

OBJECTIVE: The aim of this study was to determine the experience of patients with brain tumors and their carers across distinct parts of their treatment pathway and identify their views on potential service gaps in need of addressing. METHODS: A structured survey was administered at patient workshops across the UK and online through a charity newsletter. Answers to closed questions were analyzed using descriptive statistics, and open questions were examined using techniques of inductive content analysis. RESULTS: A total of 136 survey responses were received, representing patients with a variety of diagnoses and geographical locations (30 counties). There was a wide range of opinions on the provision of current neuro-oncology services. Key themes identified included a perceived lack of information provision, a gap in postdischarge psychological and neuropsychological supports, and an unmet willingness for involvement in research. CONCLUSION: This national survey enhances our knowledge of current patient and carer experience within neuro-oncology services. A number of areas of unmet clinical need are highlighted providing a basis for informing future patient-centered service improvements and research.

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.

Can Communication-And-Resolution Programs Achieve Their Potential? Five Key Questions.

Communication-and-resolution programs (CRPs) are intended to promote accountability, transparency, and learning after adverse events. In this article we address five key challenges to the programs' future success: implementation fidelity, the evidence base for CRPs and their link to patient safety, fair compensation of harmed patients, alignment of CRP design with participants' needs, and public policy on CRPs. While the field has arrived at an understanding of the core communication-and-resolution practices, limited adherence fuels skepticism that programs are meeting the needs of patients and families who have been injured by care or improving patient safety. Adherence to communication-and-resolution practices could be enhanced by adopting measures of CRP quality and implementing programs in a comprehensive, principled, and systematic manner. Of particular importance is offering fair compensation to patients in CRPs and supporting their right to attorney representation. There is evidence that the use of CRPs reduces liability costs, but research on other outcomes is limited. Additional research is especially needed on the links between CRPs and quality and on the programs' alignment with patients' and families' needs. By honoring principles of transparency, quality improvement, and patient and family empowerment, organizations can use their CRPs to help revitalize the medical profession.

Improving anticoagulation of patients with an implantable left ventricular assist device.

Patients supported with implantable left ventricular assist devices (LVAD) have a significant risk of bleeding and thromboembolic complications. All patients require anticoagulation with warfarin, aiming for a target international normalised ratio (INR) of 2.5 and most patients also receive antiplatelet therapy. We found marked variation in the frequency of INR measurements and proportion of time outside the therapeutic INR range in our LVAD-supported patients. As part of a quality improvement initiative, home INR monitoring and a networked electronic database for recording INR results and treatment decisions were introduced. These changes were associated with increased frequency of INR measurement. We anticipate that changes introduced in this quality improvement project will reduce the likelihood of adverse events during long-term LVAD support.
