A Prospective Randomized Controlled Pilot Simulation Study to Investigate the Effect of Audiovisual Decision Support on Diagnosis and Therapeutic Interventions.

INTRODUCTION: Combining audiovisual decision support during perioperative critical events might enhance provider diagnostic and therapeutic accuracy and efficiency. METHODS: This study is a prospective, randomized controlled pilot trial studying the impact of audiovisual decision support on anesthesia professional performance at NorthShore University HealthSystem's high fidelity simulation center. Twenty anesthesia professionals (>2 years of clinical experience in the current role) were randomized to 2 groups (current care model vs. audiovisual assistance) and underwent 3 periprocedural simulation scenarios, where patient deterioration occurs: anaphylaxis, amniotic fluid embolism, and cardiac arrest during dental case. RESULTS: Overall, there was a statistically significant decrease in the mean and median pooled times to diagnosis in both the amniotic fluid embolism and pediatric dental scenarios. There was a statistically significant increase in the number of participants in the intervention group who made diagnosis 3 before the end of the scene (P = 0.03) in the amniotic fluid embolism case. In the pediatric dental case, there was a statistically significant reduction in the median time to diagnosis 1 and diagnosis 3 in the intervention group versus control (P = 0.01 and P = 0.0002). A significant increase in the number of participants in the intervention group versus control made the correct diagnosis 2 before vital sign change 3 (P = 0.03), and more participants in the intervention group made the correct diagnosis 3 before the end of the scene when compared with control (P = 0.001). The median time to start intervention 2 during the dental case was statistically significantly greater in the intervention group versus the control (P = 0.05). All other endpoints were not statistically significant among the 3 simulation scenarios. Six questions were answered by all participants upon immediate completion of the simulation scenarios and revealed that 19 of 20 participants had delivered anesthesia care to patients similar to the 3 simulation scenarios and 18 of 20 participants reported that they would prefer audiovisual assistance to detect abnormalities in vital signs that subsequently provides appropriate diagnostic and therapeutic options. CONCLUSIONS: This pilot study suggested some significant improvement in anesthesia professional time to correct diagnosis and completion of identification of the correct diagnosis before the next vital change in the audiovisual cue group versus control, particularly in the outpatient dental case. In addition, the mean and median pooled times to diagnosis were significantly reduced by approximately 1 minute in both evaluated simulation scenarios. The postsimulation survey responses also suggest the desirability of an audiovisual decision support tool among the current anesthesia professional participants. However, overall, there were no significant differences in the time to intervention between groups in all simulation scenarios.

Intellectual Property Protection in Neurosurgery: An Overview.

This is the first article of a series that will cover strategies for the protection of neurosurgical inventions and devices through patent law. Advances in neurosurgical techniques have always been accompanied by advances in neurosurgical technology. Indeed, continuous technological innovation has been a characteristic of the profession. Intellectual property protection serves as an important incentive to innovation. The protection of intellectual property related to neurosurgery presents several issues that deserve careful consideration for neurosurgical innovation.

Travels to the tropics: Deutschtum and Fedor Krause's visits to Brazil.

Fedor Krause, the father of German neurosurgery, traveled to Latin America twice in the final years of his career (in 1920 and 1922). The associations and motivations for his travels to South America and his work there have not been well chronicled. In this paper, based on a review of historical official documents and publications, the authors describe Krause's activities in South America (focusing on Brazil) within the context of the Germanism doctrine and, most importantly, the professional enjoyment Krause reaped from his trips as well as his lasting influence on neurosurgery in South America. Fedor Krause's visits to Brazil occurred soon after World War I, when Germany sought to reestablish economic, political, cultural, and scientific power and influence. Science, particularly medicine, had been chosen as a field capable of meeting these needs. The advanced German system of academic organization and instruction, which included connections and collaborations with industry, was an optimal means to reestablish the economic viability of not only Germany but also Brazil. Krause, as a de facto ambassador, helped rebuild the German image and reconstruct diplomatic relations between Germany and Brazil. Krause's interactions during his visits helped put Brazilian neurosurgery on a firm foundation, and he left an indelible legacy of advancing professionalism and specialization in neurosurgery in Brazil.

Neurosurgical Practice in Transition: A Review.

Neurosurgery is experiencing a period of acute change driven by 2 forces: (1) the perception that the healthcare system in the United States is wasteful and that patients are receiving low "value" care, (2) the belief that quality and long-term outcomes can be measured accurately. We believe 3 important shifts will emerge as a result of these forces. First, payment models will change. They will become anchored to a concept of population health, with capitation payments on a per-patient basis going to provider entities that undertake financial risk. Second, fee-for-service payments will be tied increasingly to administrative and clinical quality measures. Finally, out-of-pocket costs for patients will increase and affect both treatment decisions and willingness to participate in restrictive health care networks. In this review, we describe these changes and discuss possible consequences. We note the changing demographics of neurosurgical practices. Overall, independent private practices, managed by the neurosurgeons, will decline. The proportion of fee-for-service cases will decrease while cases reimbursed through capitation will increase. Physician integration with provider organizations, whether via full employment, a "lease," or some other arrangement, will also increase. We note the increasing importance of quality measures, and how they are likely to affect neurosurgical practices and reimbursement. We describe the advantages and disadvantages of fee-for-service and population health; describe opportunities and risks arising from these transitions; and outline strategies to thrive in a changing environment.

Seven Ethical Issues Affecting Neurosurgeons in the Context of Health Care Reform.

Ethical discussions around health care reform typically focus on problems of social justice and health care equity. This review, in contrast, focuses on ethical issues of particular importance to neurosurgeons, especially with respect to potential changes in the physician-patient relationship that may occur in the context of health care reform.The Patient Protection and Affordable Care Act (ACA) of 2010 (H.R. 3590) was not the first attempt at health care reform in the United States but it is the one currently in force. Its ambitions include universal access to health care, a focus on population health, payment reform, and cost control. Each of these aims is complicated by a number of ethical challenges, of which 7 stand out because of their potential influence on patient care: the accountability of physicians and surgeons to individual patients; the effects of financial incentives on clinical judgment; the definition and management of conflicting interests; the duty to preserve patient autonomy in the face of protocolized care; problems in information exchange and communication; issues related to electronic health records and data security; and the appropriate use of "Big Data."Systematic social and economic reforms inevitably raise ethical concerns. While the ACA may have driven these 7 to particular prominence, they are actually generic. Nevertheless, they are immediately relevant to the practice of neurosurgery and likely to reflect the realities the profession will be obliged to confront in the pursuit of more efficient and more effective health care.
