    2016-01-01

    The purposes of this study were to assess healthcare professionals' need for information on advanced directives and to implement and evaluate an educational plan for change in knowledge and behaviors related to advanced directives. End-of-life (EOL) care is an important topic for patients to discuss with their families and healthcare professionals (HP). Needs assessment data were collected from healthcare providers at an urban trauma intensive care unit (ICU) in Louisville, Kentucky on concepts related to end-of-life. Next, healthcare professionals participated in an educational intervention focused on: knowledge about advanced directives; communication techniques for healthcare professionals to use with patients and their families; awareness of the patient's level of illness in advanced care planning; and specifics about living wills in Kentucky and how to complete one. Pre- and post-test data were collected to evaluate change in knowledge, capability an average of 8.7 years (SD = 9.1; range = 1.9-35 years) in healthcare and worked an average of 8.4 years (SD = 9.3; range = 4 months to 35 years) in their respective ICUs. Eighty-seven percent did not have an AD in place even though their perceived knowledge about AD remained moderate throughout pre- and post-test scores (3.3 to 3.8 on a 5 point scale, respectively). Total post-test scores revealed a 2% improvement in correct responses. These findings point to the need for education of healthcare providers in the ICU to increase early AD and ACP discussions with patients and their families. PMID:27183766

    Perhaps individual wishes are not always acknowledged or accepted when it comes to end-of-life care. This possibility, in conjunction with the experiences of healthcare risk managers, should cause concern in the healthcare risk management community. One particularly concerning issue where a persistent failure to honor a patient's wishes exists is with Do Not Resuscitate (DNR) orders in the perioperative arena. Despite a strong focus on informed consent and advance directives, evidence suggests a number of healthcare organizations either have no policy in place regarding DNR orders during the perioperative period, or, for those organizations that do have a policy, many call for automatic suspension of the DNR order without consultation with the patient. This latter practice poses many ethical, medico-legal, and regulatory concerns, and healthcare organizations with such a policy in place should strongly consider revisiting this practice.

    Abstract Objective To establish the prevalence of patients with advance directives in a family practice, and to describe patients’ perspectives on a family doctor’s role in initiating discussions about advance directives. Design A self-administered patient questionnaire. Setting A busy urban family medicine teaching clinic in Hamilton, Ont. Participants A convenience sample of adult patients attending the clinic over the course of a typical business week. Main outcome measures The prevalence of advance directives in the patient population was determined, and the patients’ expectations regarding the role of their family doctors were elucidated. Results The survey population consisted of 800 participants (a response rate of 72.5%) well distributed across age groups; 19.7% had written advance directives and 43.8% had previously discussed the topic of advance directives, but only 4.3% of these discussions had occurred with family doctors. In 5.7% of cases, a family physician had raised the issue; 72.3% of respondents believed patients should initiate the discussion. Patients who considered advance directives extremely important were significantly more likely to want their family doctors to start the conversation (odds ratio 3.98; P < .05). Conclusion Advance directives were not routinely addressed in the family practice. Most patients preferred to initiate the discussion of advance directives. However, patients who considered the subject extremely important wanted their family doctors to initiate the discussion. PMID:25873704

    Recent advances in microelectronics and biosensors are enabling developments of innovative biochips for advanced healthcare by providing fully integrated platforms for continuous monitoring of a large set of human disease biomarkers. Continuous monitoring of several human metabolites can be addressed by using fully integrated and minimally invasive devices located in the sub-cutis, typically in the peritoneal region. This extends the techniques of continuous monitoring of glucose currently being pursued with diabetic patients. However, several issues have to be considered in order to succeed in developing fully integrated and minimally invasive implantable devices. These innovative devices require a high-degree of integration, minimal invasive surgery, long-term biocompatibility, security and privacy in data transmission, high reliability, high reproducibility, high specificity, low detection limit and high sensitivity. Recent advances in the field have already proposed possible solutions for several of these issues. The aim of the present paper is to present a broad spectrum of recent results and to propose future directions of development in order to obtain fully implantable systems for the continuous monitoring of the human metabolism in advanced healthcare applications.

    As computing and network capabilities continue to rise, it becomes increasingly important to understand the varied applications for using them to provide healthcare. The objective of this review is to identify key characteristics and attributes of healthcare applications involving the use of advanced computing and communication technologies, drawing upon 45 research and development projects in telemedicine and other aspects of healthcare funded by the National Library of Medicine over the past 12 years. Only projects publishing in the professional literature were included in the review. Four projects did not publish beyond their final reports. In addition, the authors drew on their first-hand experience as project officers, reviewers and monitors of the work. Major themes in the corpus of work were identified, characterizing key attributes of advanced computing and network applications in healthcare. Advanced computing and network applications are relevant to a range of healthcare settings and specialties, but they are most appropriate for solving a narrower range of problems in each. Healthcare projects undertaken primarily to explore potential have also demonstrated effectiveness and depend on the quality of network service as much as bandwidth. Many applications are enabling, making it possible to provide service or conduct research that previously was not possible or to achieve outcomes in addition to those for which projects were undertaken. Most notable are advances in imaging and visualization, collaboration and sense of presence, and mobility in communication and information-resource use. PMID:21486877

    Buford, Christopher

    2014-01-01

    Some of the concerns that have been raised in connection to the use of advance directives are of the epistemic variety. Such concerns highlight the possibility that adhering to an advance directive may conflict with what the author of the directive actually wants (or would want) at the time of treatment. However, at least one objection to the employment of advance directives is metaphysical in nature. The objection to be discussed here, first formulated by Rebecca Dresser and labeled by Allen Buchanan as the slavery argument and David DeGrazia the someone else problem, aims to undermine the legitimacy of certain uses of advance directives by concluding that such uses rest upon an incorrect assumption about the identity over time of those ostensibly governed by the directives. There have been numerous attempts to respond to this objection. This paper aims to assess two strategies that have been pursued to cope with the problem. PMID:25743056

  10. A direct advance on advance directives.

    Shaw, David

    2012-06-01

    Advance directives (ADs), which are also sometimes referred to as 'living wills', are statements made by a person that indicate what treatment she should not be given in the event that she is not competent to consent or refuse at the future moment in question. As such, ADs provide a way for patients to make decisions in advance about what treatments they do not want to receive, without doctors having to find proxy decision-makers or having recourse to the doctrine of necessity. While patients can request particular treatments in an AD, only refusals are binding. This paper will examine whether ADs safeguard the autonomy and best interests of the incompetent patient, and whether legislating for the use of ADs is justified, using the specific context of the legal situation in the United Kingdom to illustrate the debate. The issue of whether the law should permit ADs is itself dependent on the issue of whether ADs are ethically justified; thus we must answer a normative question in order to answer the legislative one. It emerges that ADs suffer from two major problems, one related to autonomy and one to consent. First, ADs' emphasis on precedent autonomy effectively sentences some people who want to live to death. Second, many ADs might not meet the standard criteria for informed refusal of treatment, because they fail on the crucial criterion of sufficient information. Ultimately, it transpires that ADs are typically only appropriate for patients who temporarily lose physical or mental capacity. PMID:21133977

    2012-04-01

    Advance directives are written or oral statements that are intended to govern healthcare decision-making for their authors, for both positive and negative decisions, should they lose decisional capacity in the future. In a Europe which is facing an ageing population, advance directives play an increasing role to (help) formulate the wishes from elderly patient once they start losing the capacity to decide independently. Advance directives should not only be used as a formulation of the patients' previously made decision, but can also be used as guidelines to better understand the previous expressed wishes of the patient. If the advance directive is formulated in too vague form, the healthcare proxy and/or the healthcare trustee can help the physician interpret the directive. This broader approach towards advance directives is reflected in the case-law of the European Court of Human Rights, as well as on the European legislative level. PMID:22558655

    A patient's rights to autonomy and to participate in the decision making process is a fundamental ethical principle. However, for the non-competent patient, participation in decision-making is more problematic. A survey carried out in Israel found that less than half of the offspring of terminally ill elderly patients knew the request of their parents regarding life-supporting measures. A solution to this problem is the use of medical advance directives (MADs). In the U.S.A (in 1991) it was required by a federal law to inform every hospitalized patient of his right to use MADs. The experience from the use of MADs in the USA during the last 10 years show that: 1) Most lay persons as well as medical staff support the use of MADs 2) The rate of the use of MADs is about 20%, and among long term care hospitalized patients it is even higher. 3) Sex, age, level of education, morbidity and income were found to be significant factors. 4) Education on the use of the MADs raised the rate of use. 5) Most of the patients who had MADs did not discuss the issue of life supporting treatment with their physicians. 6) Patients who had MADs received less aggressive treatment with reduced medical cost. 7) There is a preference to write generic MADs. Arguments supporting the use of MADs state that they: extend patient autonomy; relieve patient anxiety regarding unwanted treatment; relieve physicians' anxiety concerning legal liability; reduce interfamily conflicts, and they also lower health care costs. Arguments opposing the use claim that they: violate sanctity of life; promote an adversarial physician-patient relationship; may lead to euthanasia; fail to express the patient's current wishes and may even counteract physicians' values. On the basis of experience in the USA and the positive attitude regarding MADs, it appears that MADs can also be applicable in Israel. PMID:11905092

    PubMed

    Wolff, Jonathan

    2012-10-01

    This article considers the ethics of advance directives, especially in relation to conditions such as dementia. For some choices, such as over whether one's life should end at home or in a hospice, advance directives can be very enlightened and helpful. For others, such as those to end the life of an autonomous subject, against their will, have no moral appeal and would rightly be ignored. In a wide range of intermediate cases, given our typical lack of insight into how changes in our health condition will affect us in other ways, we should be very cautious indeed in promoting the use of advance directives in end-of-life decisions, at least where a reasonable quality of life remains. There may be some reasons for giving priority to the earlier autonomous self over a later, contented but non-autonomous self, but these reasons seem far from compelling. PMID:23079306

    Suboptimal care at the end-of-life can be due to lack of access or knowledge of patient wishes. Ambiguity is often the result of non-standardized formats. Borrowing digital technology from other industries and using existing health information infrastructure can greatly improve the completion, storage, and distribution of advance directives. We believe several simple, low-cost adaptations to regional and federal programs can raise the standard of end-of-life care. PMID:25024771

    We examined the management of completed advance directives including why participants completed a document, what procedures and values they chose, with whom they held end-of-life conversations, and where they stored their document. Participants elected to complete a SurveyMonkey survey that was made available to individuals who wrote an advance directive through TexasLivingWill.org; 491 individuals elected to fill out the survey, aged 19 to 94 years. The survey asked multiple questions about why participants completed an advance directive, where they would store it, and with whom they had conversations about their end-of-life wishes. A list of procedures and values allowed participants to indicate what they refused or requested in their advance directive. Advance directives are most often completed to allow patients to prepare and control the healthcare they wish to receive when dying. One-half to two-thirds of individuals refuse common end-of-life medical procedures, and the rest request the procedures. We found a correlation between the choice to refuse or request a procedure and the age of the participant. Participants reported that their end-of-life conversations most often occurred with their spouse. Respondents often reported that their advance directive was stored with their physician and power of attorney for healthcare, conversations with those individuals rarely happened. Advance directives document patients' requests for and refusals of end-of-life care. Physicians and surrogates need to be better educated so that the documents are part of a meaningful conversation with the patient. Because patients' choices change over their lifespan, these documents need to be revisited regularly and not completed as a onetime event. PMID:26399671

    In the face of mounting criticism against advance directives, we describe how a novel, computer-based decision aid addresses some of these important concerns. This decision aid, Making Your Wishes Known: Planning Your Medical Future, translates an individual’s values and goals into a meaningful advance directive that explicitly reflects their healthcare wishes and outlines a plan for how they wish to be treated. It does this by 1) educating users about advance care planning; 2) helping individuals identify, clarify, and prioritize factors that influence their decision-making about future medical conditions; 3) explaining common end-of-life medical conditions and life-sustaining treatment; 4) helping users articulate a coherent set of wishes with regard to advance care planning—in the form of an advance directive readily interpretable by physicians; and 5) helping individuals both choose a spokesperson, and prepare to engage family, friends, and healthcare providers in discussions about advance care planning.

    Nurse coaches are responding to the mandate of Florence Nightingale (1820-1910)—the foundational philosopher of modern nursing—to advocate, identify, and focus on factors that promote health, healthy people, and healthy communities that are recognized today as environmental and social determinants of health.1,2 The Institute of Medicine report3 and other health initiatives suggest the need for increased education and leadership from nurses to address the healthcare needs of our nation and world. Nurse coaches are strategically pos-i tioned and equipped to implement health-promoting and evidence-based strategies with clients and support behavioral and lifestyle changes to enhance growth, overall health, and well-being. With possibilities not yet imagined, employment opportunities for nurses who incorporate coaching into professional practice are developing across the entire spectrum of health, well-ness, and healing.

    The advance directive is a statement of an individual's preference for future treatment. The concept initially evolved in the context of end-of-life treatment decision making. Subsequently, in some countries, advance directives have been promoted in the care and treatment of people with serious mental disorders. They have recently been endorsed by the United Nations Convention for the Rights of Persons with Disability. In India, the legal framework related to the care of persons with mental illness is currently being reappraised, and significant changes are being contemplated. Thus, this is an appropriate time to review the existing evidence on psychiatric advance directives and examine the potential challenges involved in making them legally binding. A wide spectrum of mental health 'advance statements' have been developed and implemented in some high-resource countries. Of special interest to mental health contexts is the complex Ulysses contract to accommodate situations where the advance directive can be overridden during phases of acute illness or relapse. There have been mixed experiences with advance directives in the last couple of decades and there is scant evidence to suggest that they are effective in improving actual care. There has been almost no discourse in India on the issue of mental health advance directives. Yet this feature is being considered for implementation in the revised legal framework for the care of persons with mental illness. There are significant barriers to the feasibility and acceptability of legally mandated advance directives. There are logistical barriers to operationalising them in a manner that guarantees quality assurance of the process, and minimises the possibility of misuse. Thus, while the advance directive is a highly desirable clinical tool for collaborative decision making between the person with mental illness and the treatment provider, at this time, more needs to be done before legal enforcement is considered in

    Advance directives convey consumers' wishes about accepting or refusing future treatment if they become incompetent. They are designed to communicate a competent consumer's perspective regarding the preferred treatment, should the consumer later become incompetent. There are associated ethical issues for health practitioners and this article considers the features that are relevant to nurses. In New Zealand, consumers have a legal right to use an advance directive that is not limited to life-prolonging care and includes general health procedures. Concerns may arise regarding a consumer's competence and the document's validity. Nurses need to understand their legal and professional obligations to comply with an advance directive. What role does a nurse play and what questions arise for a nurse when advance directives are discussed with consumers? This article considers the cultural dimensions, legal boundaries, consumers' and providers' perspectives, and the medical and nursing positions in New Zealand. PMID:16045243

  8. Cross-border healthcare directive: Assessing stakeholders' perspectives in Poland and Portugal.

    PubMed

    Helena, Ricardo

    2016-04-01

    Within the context of the EU, a succession of rulings from the European Court of Justice addressed the gap of specific healthcare legislation. These rulings shook the member states assumption of health provision autonomy and led the European Commission to produce a specific directive concerning cross-border healthcare. In spite of different viewpoints of member states, including Poland and Portugal, the directive was approved and expected to be implemented by October 2013. The objective of this study was to analyse stakeholders' perspective towards the directive, unveiling the factors that supported a different viewpoint, and to identify challenges and assess the expected impact associated with the directive implementation on Poland and Portugal, using the WHO health systems conceptual framework. Information was collected through a literature review, identifying potential stakeholders. Primary qualitative analysis was conducted through the dissemination of open-ended questionnaires. Content and critical analysis was performed considering the available literature intertwined with the WHO health systems conceptual framework. The directive appears to be positive regarding patient rights, increased transparency, and potential to set new information technologies and healthcare networks. However, it also seems to potentially generate access inequalities between home and foreign patients, and increase healthcare costs due to the short-term investments needed. PMID:26948704

    The adoption of technology in healthcare over the last twenty years has steadily increased, particularly as it relates to medical robotics and Multi-User Virtual Environments (MUVEs) such as Second Life. Both disciplines have been shown to improve the quality of care and have evolved, for the most part, in isolation from each other. In this paper, we present four synergies between medical robotics and MUVEs that have the potential to decrease resource utilization and improve the quality of healthcare delivery. We conclude with some foreseeable barriers and future research directions for researchers in these fields. PMID:21335746

    article provides examples of each feature. The DS literature also emphasizes the importance of organizational culture and training in implementation success. The literature contrasts “rational-analytic” vs. “naturalistic-intuitive” decision-making styles, but the best approach is often a balanced approach that combines both styles. It is also important for DS systems to enable exploration of multiple assumptions, and incorporation of new information in response to changing circumstances. Conclusions Complex, high-level decision-making has common features across disciplines as seemingly disparate as defense, business, and healthcare. National efforts to advance the health information technology agenda through broader CDS adoption could benefit by applying the DS principles identified in this review. PMID:22900537

    Natural evolution has produced a great diversity of proteins that can be harnessed for numerous applications in biotechnology and pharmaceutical science. Commonly, specific applications require proteins to be tailored by protein engineering. Directed evolution is a type of protein engineering that yields proteins with the desired properties under well-defined conditions and in a practical time frame. While directed evolution has been employed for decades, recent creative developments enable the generation of proteins with previously inaccessible properties. Novel selection strategies, faster techniques, the inclusion of unnatural amino acids or modifications, and the symbiosis of rational design approaches and directed evolution continue to advance protein engineering.

    The Advanced Automated Directional Solidification Furnace (AADSF) with the Experimental Apparatus Container (EAC) attached flew during the USMP-2 mission. This assembly consists of a furnace module, a muffle tube assembly and a translation mechanism which are enclosed in the EAC. During USMP-2, the AADSF was used to study the growth of mercury cadmium telluride crystals in microgravity by directional solidification, a process commonly used on earth to process metals and grow crystals. The furnace is tubular and has three independently controlled temperature zone . The sample travels from the hot zone of the furnace (1600 degrees F) where the material solidifies as it cools. The solidification region, known as the solid/liquid interface, moves from one end of the sample to the other at a controlled rate, thus the term directional solidification.

  13. Subnational responsibilities for healthcare and Austria's rejection of the EU's patients' rights directive.

    PubMed

    Kostera, Thomas

    2013-07-01

    In 2011, Member States and the European Parliament brought into force a Directive on the application of patients' rights in cross-border healthcare within the EU. Austria voted against this directive even though its national legislation was already in line with the rulings of the European Court of Justice which had triggered the negotiations on the directive. Why then, in the absence of any legal constraints on adapting to it, did Austria vote against the directive? The article argues that it was the federal structure of financing hospital infrastructure and the subnational level's influence on national position building which led to the rejection of the directive. The article retraces the process of position building by analyzing the interaction between the national and the subnational levels and concludes that Austria's position mirrors the national struggle between both levels of government over control of the hospital sector.

    The Advanced Energy Retrofit Guide for Healthcare Facilities is part of a series of retrofit guides commissioned by the U.S. Department of Energy. By presenting general project planning guidance as well as detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures (EEMs), the guides provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. The Advanced Energy Retrofit Guides (AERGs) are intended to address key segments of the U.S. commercial building stock: retail stores, office buildings, K-12 schools, grocery stores, and healthcare facilities. The guides' general project planning considerations are applicable nationwide; the energy and cost savings estimates for recommended EEMs were developed based on energy simulations and cost estimates for an example hospital tailored to five distinct climate regions. These results can be extrapolated to other U.S. climate zones. Analysis is presented for individual EEMs, and for packages of recommended EEMs for two project types: existing building commissioning projects that apply low-cost and no-cost measures, and whole-building retrofits involving more capital-intensive measures.

  15. [Euthanasia in advanced dementia: directive is useful].

    The Dutch Euthanasia Act states that an advance directive can replace an actual request for euthanasia in cases in which a patient has become unable to make autonomous decisions. In Euthanasia and the Severely Demented, I agree with Keizer that the severely demented can suffer unbearably, but contrary to Keizer I do not believe that it is impossible to state in advance the conditions under which one would not wish to go on living any longer. Consequently, euthanasia can be permissible even in patients with late-stage dementia, provided that the other due-care criteria are met. Permissibility by itself, however, will not settle disputes about borderline cases. Due to the erratic course of the disease, the right moment for euthanasia may very well be impossible to determine.

    The world`s first geothermal application of the Advanced Direct Contact Condenser (ADCC) technology developed by the National Renewable Energy Laboratory (NREL) is now operational at The Geysers Power Plant Unit 11. This major research effort was supported through the combined efforts of NREL, The Department of Energy (DOE), and Pacific Gas and Electric (PG&E). The project was the first geothermal adaptation of an advanced condenser design originally demonstrated at the Ocean Thermal Energy Conversion (OTEC) plant in Kona, Hawaii. PG&E expects this technology to improve power plant performance and to help extend the life of the steam field by using steam more efficiently. Successful application of this technology at The Geysers will provide a basis for NREL to continue to develop this technology for other geothermal and fossil power plant systems.

    The relationship between the patient and a medical care giver is complex specially as it implies to the human, juridical and practical points of view. It depends on legal and deontological considerations, but also on professional habits. Today, we are confronted to a fundamental modification of this relationship. Professional guidelines exist, but are rarely applied and rarely taught in universities. However, patients are eager to move from a paternalistic relationship to a true partnership, more harmonious and more respectful of individual values ("value based medicine"). Advance directives give us an opportunity to improve our practices and to provide care consistent with the needs and wishes of each patient. PMID:10967645

    The first geothermal application of the Advanced Direct Contact Condenser (ADCC) technology developed by the National Renewable Energy Laboratory (NREL) is now operational and is being tested at The Geysers Power Plant Unit 11. This major research effort is being supported through the combined efforts of NREL, The Department of Energy (DOE), and Pacific Gas and Electric (PG&E). NREL and PG&E have entered into a Cooperative Research And Development Agreement (CRADA) for a project to improve the direct-contact condenser performance at The Geysers Power Plant. This project is the first geothermal adaptation of an advanced condenser design developed for the Ocean Thermal Energy Conversion (OTEC) systems. PG&E expects this technology to improve power plant performance and to help extend the life of the steam field by using steam more efficiently. In accordance with the CRADA, no money is transferred between the contracting parties. In this case the Department of Energy is funding NREL for their efforts in this project and PG&E is contributing funds in kind. Successful application of this technology at The Geysers will provide a basis for NREL to continue to develop this technology for other geothermal and fossil power plant systems.

    Heart disease is one of the lead causes of death worldwide. Many forms of heart disease, including myocardial infarction and pressure-loading cardiomyopathies, result in irreversible cardiomyocyte death. Activated fibroblasts respond to cardiac injury by forming scar tissue, but ultimately this response fails to restore cardiac function. Unfortunately, the human heart has little regenerative ability and long-term outcomes following acute coronary events often include chronic and end-stage heart failure. Building upon years of research aimed at restoring functional cardiomyocytes, recent advances have been made in the direct reprogramming of fibroblasts toward a cardiomyocyte cell fate both in vitro and in vivo. Several experiments show functional improvements in mouse models of myocardial infarction following in situ generation of cardiomyocyte-like cells from endogenous fibroblasts. Though many of these studies are in an early stage, this nascent technology holds promise for future applications in regenerative medicine. In this review, we discuss the history, progress, methods, challenges, and future directions of direct cardiac reprogramming. PMID:26176012

    Per the Patient Self-Determination Act of 1991, hospitals are required to ascertain whether patients have an advance directive (AD). At this point, factors prompting patients to issue ADs have not been studied. The purpose of this study was to describe patients' understanding of ADs as well as the process patients used to arrive at their decisions to implement an AD. A stratified random sample of 26 patients from two intensive care units, one general medical unit, one general cardiac unit, and one acquired immunodeficiency unit were selected for participation. Patients were asked a series of open-ended questions to determine their knowledge and understanding of ADs. The constant comparative method was used to review the transcripts. It was found that only 31 per cent of patients had issued an AD, and 20% had learned of ADs for the first time during their hospitalization. Response analysis showed four phases of AD decision making: evaluation of illness, establishment of priorities, consideration of implications of the directives, and selection or rejection of directives. In conclusion, patients continue to have limited understanding of ADs and their implications. Continued investigation will elucidate the best strategies to educate patients about this topic.

  1. The Texas Advanced Directive Law: Unfinished Business.

    Kapottos, Michael; Youngner, Stuart

    2015-01-01

    The Texas Advance Directive Act allows physicians and hospitals to overrule patient or family requests for futile care. Purposefully not defining futility, the law leaves its determination in specific cases to an institutional process. While the law has received several criticisms, it does seem to work constructively in the cases that come to the review process. We introduce a new criticism: While the law has been justified by an appeal to professional values such as avoiding harm to patients, avoiding the provision of unseemly care, and good stewardship of medical resources, it is applied incompletely. It allows physicians and institutional committees to refuse "futile" treatments desired by patients and families while at the same time providing no way of regulating physicians who recommend or even push "futile" treatments in similar cases. In this sense, the TADA is incomplete on its own terms. PMID:26225515

    The subjective nature of self-reported dietary intake assessment methods presents numerous challenges to obtaining accurate dietary intake and nutritional status. This limitation can be overcome by the use of dietary biomarkers, which are able to objectively assess dietary consumption (or exposure) without the bias of self-reported dietary intake errors. The need for dietary biomarkers was addressed by the Institute of Medicine, who recognized the lack of nutritional biomarkers as a knowledge gap requiring future research. The purpose of this article is to review existing literature on currently available dietary biomarkers, including novel biomarkers of specific foods and dietary components, and assess the validity, reliability and sensitivity of the markers. This review revealed several biomarkers in need of additional validation research; research is also needed to produce sensitive, specific, cost-effective and noninvasive dietary biomarkers. The emerging field of metabolomics may help to advance the development of food/nutrient biomarkers, yet advances in food metabolome databases are needed. The availability of biomarkers that estimate intake of specific foods and dietary components could greatly enhance nutritional research targeting compliance to national recommendations as well as direct associations with disease outcomes. More research is necessary to refine existing biomarkers by accounting for confounding factors, to establish new indicators of specific food intake, and to develop techniques that are cost-effective, noninvasive, rapid and accurate measures of nutritional status.

    Background Although some studies indicate that bipolar disorder causes high health care resources consumption, no study is available addressing a cost estimation of bipolar disorder in Spain. The aim of this observational study was to evaluate healthcare resource utilization and the associated direct cost in patients with manic episodes in the Spanish setting. Methods Retrospective descriptive study was carried out in a consecutive sample of patients with a DSM-IV diagnosis of bipolar type I disorder with or without psychotic symptoms, aged 18 years or older, and who were having an active manic episode at the time of inclusion. Information regarding the current manic episode was collected retrospectively from the medical record and patient interview. Results Seven hundred and eighty-four evaluable patients, recruited by 182 psychiatrists, were included in the study. The direct cost associated with healthcare resource utilization during the manic episode was high, with a mean cost of nearly €4,500 per patient, of which approximately 55% corresponded to the cost of hospitalization, 30% to the cost of psychopharmacological treatment and 10% to the cost of specialized care. Conclusions Our results show the high cost of management of the patient with a manic episode, which is mainly due to hospitalizations. In this regard, any intervention on the management of the manic patient that could reduce the need for hospitalization would have a significant impact on the costs of the disease. PMID:20426814

    The Advanced Automated Directional Solidification Furnace (AADSF) is a five zone tubular furnace designed for Bridgman-Stockbarger, other techniques of crystal growth involving multiple temperature zones such as vapor transport experiments and other materials science experiments. The five zones are primarily designed to produce uniform hot and cold temperature regions separated by an adiabatic region constructed of a heat extraction plate and an insert to reduce radiation from the hot to the cold zone. The hot and cold zone temperatures are designed to reach 1600 C and 1100 C, respectively. AADSF operates on a Multi-Purpose Experiment Support Structure (MPESS) within the cargo bay of the Space Shuttle on the United States Microgravity Payload (USMP) missions. Two successful flights, both employing the directional solidification or Bridgman Stockbarger technique for crystal growth have been made, and crystals of HgCdTe and PbSnTe grown in microgravity have been produced on USMP-2 and USMP-3, respectively. The addition of a Sample Exchange Mechanism (SEM) will enable three different samples to be processed on future flights including the USMP-4 mission.

  5. The impact of directed choice on the design of preventive healthcare facility network under congestion.

    Preventive healthcare (PH) programs and services aim at reducing the likelihood and severity of potentially life-threatening illness by early detection and prevention. The effectiveness of these programs depends on the participation level and the accessibility of the users to the facilities providing the services. Factors that impact the accessibility include the number, type, and location of the facilities as well as the assignment of the clients to these facilities. In this paper, we study the impact of system-optimal (i.e., directed) choice on the design of the preventive healthcare facility network under congestion. We present a model that simultaneously determines the location and the size of the facilities as well as the allocation of clients to these facilities so as to minimize the weighted sum of the total travel time and the congestion associated with waiting and service delay at the facilities. The problem is set up as a network of spatially distributed M/G/1 queues and formulated as a nonlinear mixed integer program. Using simple transformation of the nonlinear objective function and piecewise linear approximation, we reformulate the problem as a linear model. We present a cutting plane algorithm based exact (-optimal) solution approach. We analyze the tradeoff between travel time and queuing time and its impact on the location and capacity of the facilities as well as the allocation of clients to these facilities under a directed choice policy. We present a case study that deals with locating mammography clinics in Montreal, Canada. The results show that incorporating congestion in the PH facility network design substantially reduces the total time spent by clients. The proposed model allows policy makers to direct clients to facilities in an equitable manner resulting in better accessibility. PMID:24879402

    Dementia is highly prevalent and incurable. The participation of dementia patients in clinical research is indispensable if we want to find an effective treatment for dementia. However, one of the primary challenges in dementia research is the patients' gradual loss of the capacity to consent. Patients with dementia are characterized by the fact that, at an earlier stage of their life, they were able to give their consent to participation in research. Therefore, the phase when patients are still competent to decide offers a valuable opportunity to authorize research, by using an advance research directive (ARD). Yet, the use of ARDs as an authorization for research participation remains controversial. In this paper we discuss the role of autonomous decision-making and the protection of incompetent research subjects. We will show why ARDs are a morally defensible basis for the inclusion of this population in biomedical research and that the use of ARDs is compatible with the protection of incompetent research subjects.

    This paper presents an overview of historical advances and the current state of genetic psychophysiology, a rapidly developing interdisciplinary research linking genetics, brain, and human behavior, discusses methodological problems, and outlines future directions of research. The main goals of genetic psychophysiology are to elucidate the neural pathways and mechanisms mediating genetic influences on cognition and emotion, identify intermediate brain-based phenotypes for psychopathology, and provide a functional characterization of genes being discovered by large association studies of behavioral phenotypes. Since the initiation of this neurogenetic approach to human individual differences in the 1970s, numerous twin and family studies have provided strong evidence for heritability of diverse aspects of brain function including resting-state brain oscillations, functional connectivity, and event-related neural activity in a variety of cognitive and emotion processing tasks, as well as peripheral psychophysiological responses. These data indicate large differences in the presence and strength of genetic influences across measures and domains, permitting the selection of heritable characteristics for gene finding studies. More recently, candidate gene association studies began to implicate specific genetic variants in different aspects of neurocognition. However, great caution is needed in pursuing this line of research due to its demonstrated proneness to generate false-positive findings. Recent developments in methods for physiological signal analysis, hemodynamic imaging, and genomic technologies offer new exciting opportunities for the investigation of the interplay between genetic and environmental factors in the development of individual differences in behavior, both normal and abnormal.

    Objectives: This research project created and evaluated a knowledge-exchange intervention designed to facilitate an increase in organizational readiness for implementing coordinated stroke care in four primarily rural provincial healthcare systems. Intervention: Knowledge brokers were linked to networks within, across and outside the provinces to support, inform and disseminate best practice recommendations for coordinated stroke care within the provincial healthcare systems. Findings: The intervention increased awareness and dissemination of recommendations, which stimulated the implementation of coordinated stroke care. Similar knowledge-exchange interventions might work in other healthcare jurisdictions with similar demographics, to promote evidence-informed improvements in healthcare. PMID:22851988

    Rationale: The United States is one of only two countries that permit direct-to-consumer advertising (DTCA) of prescription drugs, and many questions remain regarding its effects. Objectives: To quantify the association between asthma-related DTCA, pharmacy sales, and healthcare use. Methods: This was an ecological study from 2005 through 2009 using linked data from Nielsen (DTCA television ratings), the IMS Health National Prescription Audit (pharmacy sales), and the MarketScan Commercial Claims data (healthcare use) for 75 designated market areas in the United States. We used multilevel Poisson regression to model the relationship between DTCA and rates of prescriptions and use within and across designated market areas. Main outcome measures include (1) volume of total, new, and refilled prescriptions for advertised products based on pharmacy sales; (2) prescription claims for asthma medications; and asthma-related (3) emergency department use, (4) hospitalizations, and (5) outpatient encounters among the commercially insured. Measurements and Main Results: Four Food and Drug Administration–approved asthma medicines were advertised during the period examined: (1) fluticasone/salmeterol (Advair), (2) mometasone furoate (Asmanex), (3) montelukast (Singulair), and (4) budesonide/formoterol (Symbicort). After adjustment, each additional televised advertisement was associated with 2% (incident rate ratio, 1.02; 95% confidence interval, 1.01–1.03) higher pharmacy sales rate from 2005 through 2009, although this effect varied across the three consistently advertised therapies examined. Among the commercially insured, DTCA was positively and significantly associated with emergency room visits related to asthma (incident rate ratio, 1.02; 95% confidence interval, 1.01–1.04), but there was no relationship with hospitalizations or outpatient encounters. Conclusions: Among this population, DTCA was associated with higher prescription sales and asthma-related emergency

    Background Infections are common in advanced dementia. Little is known about healthcare proxy involvement in decision making regarding infections. Design Prospective cohort study Setting/Participants 362 nursing home (NH) residents with advanced dementia and their proxies in 35 Boston-area facilities. Measurements Charts were abstracted monthly (up to 12 months) for documentation of suspected infections and provider/proxy discussions for each episode. Proxies were interviewed within 8 weeks of the infection to determine their awareness and decision-making involvement. Factors associated with proxy awareness and discussion documentation were identified. Results There were 496 suspected infections; proxies were reached for interview for 395 (80%). Proxy/provider discussions were documented for 207/395 episodes (52%), yet proxies were aware of only 156/395 (39%). Proxies participated in decision-making for 89/156 (57%) episodes of which they were aware. Proxy awareness was associated with antimicrobial use (adjusted odds ratio (AOR) 3.43, 95% confidence interval (CI) 1.94–6.05), hospital transfer (AOR 3.00, 95% CI 1.19–7.53), infection occurrence within 30 days of death (AOR 3.32, 95% CI 1.54–7.18) and fewer days between infection and study interview (AOR 2.71, 95% CI 1.63–4.51). Discussion documentation was associated with the resident residing in a dementia special care unit (AOR 1.71, 95% CI 1.04–2.80), not on hospice (AOR 3.25, 95% CI 1.31–8.02), more provider visits (AOR 1.71, 95% CI 1.07–2.75), proxy visits > 7 hours/week (AOR 1.93, 95% CI 1.02–3.67), and episode within 30 days of death (AOR 3.99, 95% CI 1.98–8.02). Conclusion Proxies are unaware of and do not participate in decision-making for most suspected infections experienced by NH residents with advanced dementia. Proxy awareness of episodes and documentation of provider/proxy discussions are not congruent. PMID:26031905

    Currently, chemotherapy is an accredited, standard treatment for unresectable, advanced pancreatic cancer (PC). However, it has been still showed treatment-resistance and followed dismal prognosis in many cases. Therefore, some sort of new, additional treatments are needed for the better therapeutic results for advanced PC. According to the previous reports, it is obvious that interventional endoscopic ultrasonography (EUS) is a well-established, helpful and low-risky procedure in general. As the additional treatments of the conventional therapy for advanced PC, many therapeutic strategies, such as immunotherapies, molecular biological therapies, physiochemical therapies, radioactive therapies, using siRNA, using autophagy have been developing in recent years. Moreover, the efficacy of the other potential therapeutic targets for PC using EUS-fine needle injection, for example, intra-tumoral chemotherapeutic agents (paclitaxel, irinotecan), several ablative energies (radiofrequency ablation and cryothermal treatment, neodymium-doped yttrium aluminum garnet laser, high-intensity focused ultrasound), etc., has already been showed in animal models. Delivering these promising treatments reliably inside tumor, interventional EUS may probably be indispensable existence for the treatment of locally advanced PC in near future. PMID:26677434

  14. Advance directives and personal identity: what is the problem?

    PubMed

    Furberg, Elisabeth

    2012-02-01

    The personal identity problem expresses the worry that due to disrupted psychological continuity, one person's advance directive could be used to determine the care of a different person. Even ethicists, who strongly question the possibility of the scenario depicted by the proponents of the personal identity problem, often consider it to be a very potent objection to the use of advance directives. Aiming to question this assumption, I, in this paper, discuss the personal identity problem's relevance to the moral force of advance directives. By putting the personal identity argument in relation to two different normative frameworks, I aim to show that whether or not the personal identity problem is relevant to the moral force of advance directives, and further, in what way it is relevant, depends entirely on what normative reasons we have for respecting advance directives in the first place.

    PubMed

    Musfeldt, C; Hart, R I

    1993-01-01

    The most effective way to improve quality is to reduce variation in the processes of providing a service. Physician-Directed Diagnostic and Therapeutic (PDDT) Plans are a proven methodology for reducing variation in clinical processes and improving the quality of care. A major part of the PDDT Plan process is the development of a critical pathway. Critical pathways are an application of Total Quality Management (TQM) principles to clinical care which have provided clear, tangible results in those hospitals committed to this process. These pathways define the processes, timelines and responsibilities associated with the patient's clinical needs from preadmission to post discharge. Representatives of the various health-care professions involved in treating the specified patient populations work together, led by a physician, to define the processes of care. When completed, everyone involved in treating the patient understands what is to be done, by whom, and when. The pathways allow clinicians to plan ahead and let the patient and family know what to expect. Through establishing standards of care, these critical pathways also reduce the uncertainty of treatment decisions and free physicians from having to practice defensive medicine, and thus reduce cost. While the most visible outcome of this process is the actual PDDT Plan, it is not necessarily the most important. The very process of designing the pathway improves intra- and interdisciplinary communication, and fosters teamwork. PMID:8268471

We first discuss common analytical methods for characterizing the size, shape, and quality of nanoelectrodes, including electron microscopy, steady-state cyclic voltammetry, scanning electrochemical microscopy, and surface modification. We then emphasize recent developments in fabrication techniques that have led to structurally well-defined nanoelectrodes. We highlight recent advances in the application of nanoelectrodes in important analytical chemistry areas, such as single-molecule studies, single-nanoparticle electrochemistry, and measurements of neurotransmitters from single neuronal cells.

    2015-01-01

    Racial/ethnic disparities in healthcare are widespread in the United States and are prevalent across healthcare organizations, including the “equal access” Veterans’ Affairs (VA) integrated healthcare system. Despite substantial attention to these disparities over the last decade, there has been limited progress in reducing them. Based on a review of evidence commissioned by the VA to guide its efforts to address racial and ethnic disparities, the conceptual framework describes the root causes of disparities in healthcare quality and outcomes, demonstrating why improvements in the quality of medical care have had limited influence over healthcare disparities that depend largely on social determinants of health. The recommended interventions—including care coordination, culturally-tailored health education, and community health workers—extend the reach of health systems beyond clinics and hospitals and into the communities and social and cultural contexts in which patients live, and in which most health promotion activities occur. To make inroads into addressing disparities, healthcare systems will need to move beyond conceptualizing care delivery as constrained to the clinical encounter and instead, incorporate an understanding of the social determinants of health.

    According to the Dutch euthanasia law, the current wishes of the patient can be replaced by an advance directive if the patient is unable to give consent. However, Dutch physicians say they have difficulty responding to advance directives in people with dementia. A crucial issue is how to establish whether the patient actually suffers in a specific situation. We argue that the patient's wishes, views and decisions should be discussed in a timely manner, and laid down both in patient directives and in the doctor's files. We also ask for regular discussion, updating and reaffirmation of the advance directive so that the patient can trust the doctor knowing the patient's wishes and what constitutes unbearable suffering for that patient. Through frequent discussion and reaffirmation, the advance directive can play the role intended by the law on euthanasia. PMID:25424631

    The possibility of using advance directives to prospectively consent to research participation in the event of dementia remains largely unexplored in Europe. Moreover, the legal status of advance directives for research is unclear in the European regulations governing biomedical research. The article explores the place that advance research directives have in the current European legal framework, and considers the possibility of integrating them more explicitly into the existing regulations. Special focus is placed on issues regarding informed consent, the role of proxies, and the level of acceptable risks and burdens. PMID:27228684

    Fuel cells that can operate directly on fuels such as methanol are attractive for low to medium power applications in view of their low weight and volume relative to other power sources. A liquid feed direct methanol fuel cell has been developed based on a proton exchange membrane electrolyte and Pt/Ru and Pt catalyzed fuel and air/O2 electrodes, respectively. The cell has been shown to deliver significant power outputs at temperatures of 60 to 90 C. The cell voltage is near 0.5 V at 300 mA/cm(exp 2) current density and an operating temperature of 90 C. A deterrent to performance appears to be methanol crossover through the membrane to the oxygen electrode. Further improvements in performance appear possible by minimizing the methanol crossover rate.

    The purpose of this report is to provide further information about vaccine information statements (VISs) that are revolutionary but neglected educational advances in the United States. Because the use of VISs is mandated by the Federal Government in every individual being immunized, it is the goal of this report to further awaken health professionals and society to the mandatory use of these superb educational statements. With the passage of the National Childhood Vaccine Injury Act of 1986, the Federal Government required that VISs would be given to all vaccine recipients. As of September 2001, the VISs that must be used are diphtheria, tetanus, pertussis, (DTaP); diphtheria, tetanus (Td); measles, mumps, rubella (MMR); polio (IPV); hepatitis B; Haemophilus influenzae type b (Hib); varicella; and pneumococcal conjugate. Copies of the VISs are available at www.cdc.gov/nip/publications/VIS. The National Childhood Vaccine Injury Act of 1986 mandated that all health care providers report certain adverse events that occur following vaccination. As a result, the Vaccine Adverse Events Reporting System (VAERS) was established by the FDA and the Centers for Disease Control and Prevention (CDC) in 1990. In order to reduce the liability of manufacturers and healthcare providers, the National Childhood Vaccine Injury Act of 1986 established the National Vaccine Injury Compensation Program (NVICP). This program is intended to compensate those individuals who have been injured by vaccines on a no-fault basis. While the use of VISs has been mandated since 1996, a national survey of private practice office settings has revealed that many immunized patients do not receive the VISs. When these forms were used, physicians rarely initiated discussions regarding contraindications to immunizations or the National Vaccine Injury Compensation Program. Fortunately, the state boards of medical examiners, like the one in Oregon, are taking a strong stand for the use of VISs, with the

    Advance directives promise patients a say in their future care but actually have had little effect. Many experts blame problems with completion and implementation, but the advance directive concept itself may be fundamentally flawed. Advance directives simply presuppose more control over future care than is realistic. Medical crises cannot be predicted in detail, making most prior instructions difficult to adapt, irrelevant, or even misleading. Furthermore, many proxies either do not know patients' wishes or do not pursue those wishes effectively. Thus, unexpected problems arise often to defeat advance directives, as the case in this paper illustrates. Because advance directives offer only limited benefit, advance care planning should emphasize not the completion of directives but the emotional preparation of patients and families for future crises. The existentialist Albert Camus might suggest that physicians should warn patients and families that momentous, unforeseeable decisions lie ahead. Then, when the crisis hits, physicians should provide guidance; should help make decisions despite the inevitable uncertainties; should share responsibility for those decisions; and, above all, should courageously see patients and families through the fearsome experience of dying.

    Given the low cost of petroleum crude, direct coal liquefaction is still not an economically viable process. The DOE objectives are to further reduce the cost of coal liquefaction to a more competitive level. In this project the primary focus is on the use of low-rank coal feedstocks. A particular strength is the use of process-derived liquids rather than model compound solvents. The original concepts are illustrated in Figure 1, where they are shown on a schematic of the Wilsonville pilot plant operation. Wilsonville operating data have been used to define a base case scenario using run {number_sign}263J, and Wilsonville process materials have been used in experimental work. The CAER has investigated: low severity CO pretreatment of coal for oxygen rejection, increasing coal reactivity and mg inhibiting the propensity for regressive reactions; the application of more active. Low-cost Fe and Mo dispersed catalysts; and the possible use of fluid coking for solids rejection and to generate an overhead product for recycle. CONSOL has investigated: oil agglomeration for coal ash rejection, for the possible rejection of ash in the recycled resid, and for catalyst addition and recovery; and distillate dewaxing to remove naphthenes and paraffins, and to generate an improved quality feed for recycle distillate hydrogenation. At Sandia, research has been concerned with the production of active hydrogen donor distillate solvent fractions produced by the hydrogenation of dewaxed distillates and by fluid coking via low severity reaction with H{sub 2}/CO/H{sub 2}O mixtures using hydrous metal oxide and other catalysts.

    2006-01-01

    Psychiatric advance directives help promote patient involvement in treatment and expedite psychiatric care. However, clinicians are unsure of how to use directives, partly due to poor clarity regarding standards for capacity to create, use, and revoke them. This article recommends possible capacity standards. Capacity to create directives is a legal presumption, supported by empirical data. Standards are discussed for the subset of cases in which capacity assessment is needed. Use of directives may be triggered by incapacity to provide informed consent to treatment, although tailored, individualized points of activation may also be considered. In many states, revocation of a psychiatric advance directive requires adequate decision-making capacity. Setting a capacity standard for revocation presents challenges, however, in light of obstacles to providing treatment when revocation is attempted and the fact that many patients prefer revocable directives. As more directives are created and used, additional research and statutory refinements are warranted. PMID:17185480

    Consol is coordinating a program designed to bridge the gap between the advanced, modern techniques of the analytical chemist and the application of those techniques by the direct coal liquefaction process developer, and to advance our knowledge of the process chemistry of direct coal liquefaction. The program is designed to provide well-documented samples to researchers who are utilizing techniques potentially useful for the analysis of coal derived samples. The choice of samples and techniques was based on an extensive survey made by Consol of the present status of analytical methodology associated with direct coal liquefaction technology. Sources of information included process developers and analytical chemists. Identified in the survey are a number of broadly characterizable needs. These categories include a need for: A better understanding of the nature of the high molecular weight, non-distillable residual materials (both soluble and insoluble) in the process streams; improved techniques for molecular characterization, heteroatom and hydrogen speciation and a knowledge of the hydrocarbon structural changes across coal liquefaction systems; better methods for sample separation; application of advanced data analysis methods; the use of more advanced predictive models; on-line analytical techniques; and better methods for catalyst monitoring.

    Ensuring that publicly funded health systems are democratically accountable is an enduring challenge in policy and practice. One strategy for enhancing public officials' accountability is to elect members of the public to oversee their performance. Several countries have experimented with direct elections to healthcare organizations. The most directly comparable examples involve some Canadian regional health authorities, New Zealand district health boards, foundation trusts in England and health boards in Scotland. We propose three aspects of the process by which the democratizing effects of elections should be judged: authorization, accountability and influence. Evidence from these countries suggests that the democratization of health systems is a complex task, which cannot be completed simply by introducing elections.

    Background Organizational context has the potential to influence the use of new knowledge. However, despite advances in understanding the theoretical base of organizational context, its measurement has not been adequately addressed, limiting our ability to quantify and assess context in healthcare settings and thus, advance development of contextual interventions to improve patient care. We developed the Alberta Context Tool (the ACT) to address this concern. It consists of 58 items representing 10 modifiable contextual concepts. We reported the initial validation of the ACT in 2009. This paper presents the second stage of the psychometric validation of the ACT. Methods We used the Standards for Educational and Psychological Testing to frame our validity assessment. Data from 645 English speaking healthcare aides from 25 urban residential long-term care facilities (nursing homes) in the three Canadian Prairie Provinces were used for this stage of validation. In this stage we focused on: (1) advanced aspects of internal structure (e.g., confirmatory factor analysis) and (2) relations with other variables validity evidence. To assess reliability and validity of scores obtained using the ACT we conducted: Cronbach's alpha, confirmatory factor analysis, analysis of variance, and tests of association. We also assessed the performance of the ACT when individual responses were aggregated to the care unit level, because the instrument was developed to obtain unit-level scores of context. Results Item-total correlations exceeded acceptable standards (> 0.3) for the majority of items (51 of 58). We ran three confirmatory factor models. Model 1 (all ACT items) displayed unacceptable fit overall and for five specific items (1 item on adequate space for resident care in the Organizational Slack-Space ACT concept and 4 items on use of electronic resources in the Structural and Electronic Resources ACT concept). This prompted specification of two additional models. Model 2 used

    Some individuals fear living with advanced dementia and may even commit suicide if they receive dementia diagnosis. Living with advanced dementia could be prevented if a person who cannot feed himself or herself would not be fed by others. The purpose of the study was to find out how acceptable would be an advance directive that includes discontinuation of feeding at certain stage of dementia for relatives of persons who died with dementia. All participants of 2 focus groups would be willing to indicate at least 1 condition in which they would not want to be fed. Some of them would be willing to make a proxy decision to stop feeding in the absence of advance directives. PMID:25313239

    Several studies have explored differences between North American and European doctor-patient relationships. They have focused primarily on differences in philosophical traditions and historic and socio-economic factors between these two regions that might lead to differences in behaviour, as well as divergent concepts in and justifications of medical practice. However, few empirical intercultural studies have been carried out to identify in practice these cultural differences. This lack of standard comparative empirical studies led us to compare differences between France and the USA regarding end-of-life decision making. We tested certain assertions put forward by bioethicists concerning the impact of culture on the acceptance of advance directives in such decisions. In particular, we compared North American and French intensive care professional’s attitudes toward: 1) advance directives and 2) the role of the family in decisions to withhold or withdraw life-support.

    Background An advance directive is a document specifying a person’s preferences for treatment, should he or she lose capacity to make such decisions in the future. They have been used in end-of-life settings to direct care but should be well suited to the mental health setting. Objectives To examine the effects of advance treatment directives for people with severe mental illness. Search methods We searched the Cochrane Schizophrenia Group’s Register (February 2008), the Cochrane Library (Issue 1 2008), BIOSIS (1985 to February 2008), CINAHL (1982 to February 2008), EMBASE (1980 to February 2008), MEDLINE (1966 to February 2008), PsycINFO (1872 to February 2008), as well as SCISEARCH and Google - Internet search engine (February 2008). We inspected relevant references and contacted first authors of included studies. We updated this search on 17 May 2012 and added the results to the awaiting classification section of the review. Selection criteria We included all randomised controlled trials (RCTs), involving adults with severe mental illness, comparing any form of advance directive with standard care for health service and clinical outcomes. Data collection and analysis We extracted data independently. For homogenous dichotomous data we calculated fixed-effect relative risk (RR) and 95% confidence intervals (CI) on an intention-to-treat basis. For continuous data, we calculated weighted mean differences (WMD) and their 95% confidence interval again using a fixed-effect model. Main results We were able to include two trials involving 321 people with severe mental illnesses. There was no significant difference in hospital admission (n=160, 1 RCT, RR 0.69 0.5 to 1.0), or number of psychiatric outpatient attendances between participants given advanced treatment directives or usual care. Similarly, no significant differences were found for compliance with treatment, self harm or number of arrests. Participants given advanced treatment directives needed less use of

  8. Physician orders to supplement advance directives: rescuing patient autonomy.

    PubMed

    Miller, Ronald B

    2009-01-01

    To adapt Churchill's comment on democracy, "No one pretends that [POLSTs are] perfect..." but physicians' orders about life-sustaining treatments are a very important supplement to advance directives, especially for patients who are extremely or terminally ill, and most particularly for patients who require emergency treatment by first responders or by physicians who do not know them as persons. The standardized orders of limited options, however, are no substitute for a detailed treatment directive of a patient with a known illness, with predictable trajectories and complications. And, in this latter circumstance, a thoroughly informed proxy may also assist physicians in selecting appropriate treatment for patients who have lost decisional capacity and/or the ability to express it. I believe all patients should have an advance directive, preferably a combined proxy-treatment directive, and preferably one that has been thoroughly discussed with the attending physician and with the proxy, successor proxies, and preferably relatives and friends. Nurses, social workers, and chaplains may be very helpful to the patient in thinking through his or her preferences, especially if the severity of illness and the limited efficacy of interventions are such that the patient would wish to omit life-sustaining treatment or to discontinue it after a time-limited trial. Finally, because POLST is new or yet to be initiated in many areas of the country, it behooves all physicians to become knowledgeable of POLST and to initiate discussion of it with colleagues, patients, patients' proxies, and with relatives of patients. Even more recent is the combined advance directive/physician's orders to permit natural dying, actionable immediately for patients suffering severely and irremediably, but actionable at a future time if the patient progresses to advanced stages of dementia or other devastating brain disorders. In order to encourage physicians to initiate advance care planning with

First, we offer a "Sample Policy and Procedure" addressing the administrative process of advance directives. This sample policy was adapted from a policy shared by Jean Clark, RRA, operations director with Roper Hospital in Charleston, SC, and a director on the AHIMA Board of Directors. Do not automatically accept this policy and procedure for your organization. Instead, the health information management professional could use this sample to write your organization's own, specific policy and procedures that are consistent with your state's law and legal counsel's advice. The second article, "Advance Directives and the New Joint Commission Requirements," compares 1992 Joint Commission standards for Patient Rights and The Patient Self-Determination Act requirements. Selected sections from the Joint Commission chapter on Patient Rights are highlighted and comments added that contrast it with the act. "Common Questions and Answers Related to Advance Directives" is the third tool we offer. These questions and answers may be used for a patient education brochure or staff inservice education program outline. Again, information specific to your own state needs to be added. The fourth tool we offer is miniature "Sample Slides" or overhead transparency copy that can be enlarged and used for a presentation on the basics of advance directives for a community group for staff education.

    Canada began research on space-relevant biological life support systems in the early 1990s. Since that time Canadian capabilities have grown tremendously, placing Canada among the emerging leaders in biological life support systems. The rapid growth of Canadian expertise has been the result of several factors including a large and technically sophisticated greenhouse sector which successfully operates under challenging climatic conditions, well planned technology transfer strategies between the academic and industrial sectors, and a strong emphasis on international research collaborations. Recent activities such as Canada's contribution of the Higher Plant Compartment of the European Space Agency's MELiSSA Pilot Plant and the remote operation of the Arthur Clarke Mars Greenhouse in the Canadian High Arctic continue to demonstrate Canadian capabilities with direct applicability to advanced life support systems. There is also a significant latent potential within Canadian institutions and organizations with respect to directly applicable advanced life support technologies. These directly applicable research interests include such areas as horticultural management strategies (for candidate crops), growth media, food processing, water management, atmosphere management, energy management, waste management, imaging, environment sensors, thermal control, lighting systems, robotics, command and data handling, communications systems, structures, in-situ resource utilization, space analogues and mission operations. With this background and in collaboration with the Canadian aerospace industry sector, a roadmap for future life support contributions is presented here. This roadmap targets an objective of at least 50% food closure by 2050 (providing greater closure in oxygen, water recycling and carbon dioxide uptake). The Canadian advanced life support community has chosen to focus on lunar surface infrastructure and not low Earth orbit or transit systems (i.e. microgravity

    The opportunity for a patient with advanced cancer to travel abroad may, for some, be a life affirming event during a dark period in their life. For others, what they hoped to be a time of joy may become an unmitigated disaster if they become unwell while away from the safety net of local cancer services. The rise of low budget airlines and cheaper foreign travel has led to an increase in the number of people travelling by air. Health professionals are more likely to face requests by patients to advise them on travel plans. Although foreign travel is an unrealistic goal for some patients, appropriate forward planning and proactive management can allow some patients to make an important journey abroad. This paper looks at the practical issues facing cancer patients who intend to travel overseas and offers practical advice on considerations that need to be made. PMID:17621611

    Acute episodes of mental illness temporarily destroy the capacity required to give informed consent and often prevent people from realizing they are sick, causing them to refuse intervention. Once a person refuses treatment, the only way to obtain care is as an involuntary patient. Even in the midst of acute episodes, many people do not meet commitment criteria because they are not likely to injure themselves or others and are still able to care for their basic needs. Left untreated, the episode will likely spiral out of control. By the time the person finally meets strict commitment criteria, devastation has already occurred. This Article argues that an individual should have the right to enter a Ulysses arrangement, a special type of mental health advance directive that authorizes a doctor to administer treatment during a future episode even if the episode causes the individual to refuse care. The Uniform Law Commissioners enacted the Uniform Health-Care Decisions Act as a model statute to address all types of advance health care planning, including planning for mental illness. However, the Act focuses on end-of-life care and fails to address many issues faced by people with mental illness. For example, the Act does not empower people to enter Ulysses arrangements and eliminates writing and witnessing requirements that protect against fraud and coercion. This Article recommends that the Uniform Law Commissioners adopt a model mental health advance directive statute that empowers people to enter Ulysses arrangements and provides safeguards against abuse. Appendix A sets forth model provisions. PMID:25051651

    Light activation of neurons is a growing field with applications ranging from basic investigation of neuronal systems to the development of new therapeutic methods such as artificial retina. Many recent studies currently explore novel methods for optical stimulation with temporal and spatial precision. Novel materials in particular provide an opportunity to enhance contemporary approaches. Here we review recent advances towards light directed interfaces for neuronal stimulation, focusing on state-of-the-art nanoengineered devices. In particular, we highlight challenges and prospects towards improved retinal prostheses. PMID:24872704

    The American Medical Association's Board of Trustees recently issued a report on advance medical directives, Living Wills, Durable Powers of Attorney, and Durable Powers of Attorney for Health Care (AMA; 1989). Here Orentlicher, writing under the auspices of the AMA's Office of the General Counsel, offers an expanded version of that report. Orentlicher's article discusses the advantages and drawbacks of living wills, the appointment of a proxy decision maker through a living will, a durable power of attorney, or a durable power of attorney for health care, and the physician's role in implementing treatment preferences.

    Oran, E. S.; Oh, C. K.; Cybyk, B. Z.

    The principles of and procedures for implementing direct simulation Monte Carlo (DSMC) are described. Guidelines to inherent and external errors common in DSMC applications are provided. Three applications of DSMC to transitional and nonequilibrium flows are considered: rarefied atmospheric flows, growth of thin films, and microsystems. Selected new, potentially important advances in DSMC capabilities are described: Lagrangian DSMC, optimization on parallel computers, and hybrid algorithms for computations in mixed flow regimes. Finally, the limitations of current computer technology for using DSMC to compute low-speed, high-Knudsen-number flows are outlined as future challenges.

  18. Advancing the science of measurement of diagnostic errors in healthcare: the Safer Dx framework

    Diagnostic errors are major contributors to harmful patient outcomes, yet they remain a relatively understudied and unmeasured area of patient safety. Although they are estimated to affect about 12 million Americans each year in ambulatory care settings alone, both the conceptual and pragmatic scientific foundation for their measurement is under-developed. Health care organizations do not have the tools and strategies to measure diagnostic safety and most have not integrated diagnostic error into their existing patient safety programs. Further progress toward reducing diagnostic errors will hinge on our ability to overcome measurement-related challenges. In order to lay a robust groundwork for measurement and monitoring techniques to ensure diagnostic safety, we recently developed a multifaceted framework to advance the science of measuring diagnostic errors (The Safer Dx framework). In this paper, we describe how the framework serves as a conceptual foundation for system-wide safety measurement, monitoring and improvement of diagnostic error. The framework accounts for the complex adaptive sociotechnical system in which diagnosis takes place (the structure), the distributed process dimensions in which diagnoses evolve beyond the doctor's visit (the process) and the outcomes of a correct and timely “safe diagnosis” as well as patient and health care outcomes (the outcomes). We posit that the Safer Dx framework can be used by a variety of stakeholders including researchers, clinicians, health care organizations and policymakers, to stimulate both retrospective and more proactive measurement of diagnostic errors. The feedback and learning that would result will help develop subsequent interventions that lead to safer diagnosis, improved value of health care delivery and improved patient outcomes.

    The direct-to-consumer genetic testing debate reached a fever pitch in November 2013 when the US Food and Drug Administration (FDA) instructed 23andMe to discontinue marketing and sale of their Personal Genome Service. In 2015, 23andMe emerged with FDA approval to market a carrier test for Bloom syndrome only, and plans to release additional reports. The dust has settled and it is time to ask: What have we learned, and where do we go from here? PMID:26517013

    Direct methanol fuel cells for portable power applications have been advanced significantly under DARPA- and ARO-sponsored programs over the last five years. A liquid-feed direct methanol fuel cell developed under these programs, employs a proton exchange membrane as electrolyte and operates on aqueous solutions of methanol with air or oxygen as the oxidant. Power densities as high as 320 mW/cm{sup 2} have been demonstrated. Demonstration of five-cell stack based on the liquid-feed concept have been successfully performed by Giner Inc. and the Jet Propulsion Laboratory. Over 2000 hours of life-testing have been completed on these stacks. These fuel cells have been also been demonstrated by USC to operate on alternate fuels such as trimethoxymethane, dimethoxymethane and trioxane. Reduction in the parasitic loss of fuel across the fuel cell, a phenomenon termed as {open_quotes}fuel crossover{close_quotes} has been achieved using polymer membranes developed at USC. As a result efficiencies as high as 40% is considered attainable with this type of fuel cell. The state-of-development has reached a point where it is now been actively considered for stationary, portable and transportation applications. The research and development issues have been the subject of several previous articles and the present article is an attempt to summarize the key advances in this technology.

    Physician-assisted suicide laws in Oregon and Washington require the person's current competency and a prognosis of terminal illness. In The Netherlands voluntariness and unbearable suffering are required for euthanasia. Many people are more concerned about the loss of autonomy and independence in years of severe dementia than about pain and suffering in their last months. To address this concern, people could write advance directives for physician-assisted death in dementia. Should such directives be implemented even though, at the time, the person is no longer competent and would not be either terminally ill or suffering unbearably? We argue that in many cases they should be, and that a sliding scale which considers both autonomy and the capacity for enjoyment provides the best justification for determining when: when written by a previously well-informed and competent person, such a directive gains in authority as the later person's capacities to generate new critical interests and to enjoy life decrease. Such an extension of legalized death assistance is grounded in the same central value of voluntariness that undergirds the current more limited legalization. PMID:23802899

    Barriers to traditional advance care planning (ACP) and advance directive (AD) creation have limited the promise of ACP/AD for individuals and families, the healthcare team, and society. Our objectives were to determine the results of a digital ACP/AD through which consumers create, store, locate, and retrieve their ACP/AD at no charge and with minimal physician involvement, and the ACP/AD can be integrated into the electronic health record. The authors chose 900 users of MyDirectives, a digital ACP/AD tool, to achieve proportional representation of all 50 states by population size and then reviewed their responses. The 900 participants had an average age of 50.8 years (SD = 16.6); 84% of the men and 91% of the women were in self-reported good health when signing their ADs. Among the respondents, 94% wanted their physicians to consult a supportive and palliative care team if they were seriously ill; nearly 85% preferred cessation of life-sustaining treatments during their final days; 76% preferred to spend their final days at home or in a hospice; and 70% would accept attempted cardiopulmonary resuscitation in limited circumstances. Most respondents wanted an autopsy under certain conditions, and 62% wished to donate their organs. In conclusion, analysis of early experience with this ACP/AD platform demonstrates that individuals of different ages and conditions can engage in an interrogatory process about values, develop ADs that are more nuanced than traditional paper-based ADs in reflecting those values, and easily make changes to their ADs. Online ADs have the potential to remove barriers to ACP/AD and thus further improve patient-centered end-of-life care. PMID:27365867

    While HIV has become a largely chronic disease, age-associated comorbidities are prevalent in people living with HIV (PLWH). Therefore, PLWH are appropriate for advance care planning (ACP) and advance directives (ADs) completion. We sought to characterize AD completion among outpatient PLWH. We conducted a retrospective chart review of PLWH who receive their routine care at the University of Wisconsin HIV clinic. Data were extracted from the electronic health record. Variables were entered into a stepwise multivariate logistic regression model to assess which factors were independently associated with AD completion. Five hundred and eighty eight charts were reviewed. Eighty-one percent of subjects were male and 72% were white; mean age was 46.8 years. ADs were completed by 134 subjects and 6.7% of those were completed at the HIV clinic. In the final multivariate model, those who had completed an AD were more likely to be older than age 45; ever been diagnosed with AIDS; have cardiovascular disease, neurologic disorder, chronic kidney disease, or malignancy. In this study, a small percentage of patients had documented ADs, with only a small proportion completed in the HIV clinic. The HIV clinic is an underutilized resource to offer ACP. Interventions are needed to provide the necessary ACP resources for PLWH. PMID:25307722

    ABSTRACT Project Title: Recovery Act: Advanced Direct Methanol Fuel Cell for Mobile Computing PROJECT OBJECTIVE The objective of the project was to advance portable fuel cell system technology towards the commercial targets of power density, energy density and lifetime. These targets were laid out in the DOE’s R&D roadmap to develop an advanced direct methanol fuel cell power supply that meets commercial entry requirements. Such a power supply will enable mobile computers to operate non-stop, unplugged from the wall power outlet, by using the high energy density of methanol fuel contained in a replaceable fuel cartridge. Specifically this project focused on balance-of-plant component integration and miniaturization, as well as extensive component, subassembly and integrated system durability and validation testing. This design has resulted in a pre-production power supply design and a prototype that meet the rigorous demands of consumer electronic applications. PROJECT TASKS The proposed work plan was designed to meet the project objectives, which corresponded directly with the objectives outlined in the Funding Opportunity Announcement: To engineer the fuel cell balance-of-plant and packaging to meet the needs of consumer electronic systems, specifically at power levels required for mobile computing. UNF used existing balance-of-plant component technologies developed under its current US Army CERDEC project, as well as a previous DOE project completed by PolyFuel, to further refine them to both miniaturize and integrate their functionality to increase the system power density and energy density. Benefits of UNF’s novel passive water recycling MEA (membrane electrode assembly) and the simplified system architecture it enabled formed the foundation of the design approach. The package design was hardened to address orientation independence, shock, vibration, and environmental requirements. Fuel cartridge and fuel subsystems were improved to ensure effective fuel

    Advance directives (AD) are written documents that give patients the opportunity to communicate their preferences regarding treatments they do or do not want to receive in case they become unable to make decisions. Commonly used pre-printed forms have different formats. Some offer space for patients to (a) appoint a surrogate decision maker, and/or (b) to determine future medical treatments and/or (c) give a statement of personal values. So far it is unknown which forms GPs preferably use and why they decide to do so. 23 semi-structured interviews with GPs were analysed using content analysis. Interviewees mainly use short templates (to appoint surrogate decision makers) and medium length templates with checkboxes to indicate patients' preferences in regards to life prolonging measures. Especially when patients faced the progression of a disease, participants use the latter version. Only then, the interviewees remarked, patients are capable to rate concrete situations reliably. GPs also realize the importance of the verbal assessment of patients' preferences; however they rarely keep a written form of the conversation. Some GPs hand out one or more templates and ask their patients to read and think about them at home with the option to talk to them about it later on, while others prefer their patients to fill them out alone at home. Regardless of template usage, most GPs emphasize that ADs require regular updates. GPs tend to see standardized advance directives mainly as a tool to start a conversation with their patients and to identify their real preferences and values. When the patient is still not facing the progression of an already existing disease it could be sufficient to only appoint a surrogate decision maker instead of creating a full AD. However, in all other situations, appointing a surrogate decision maker should be backed up by a written statement of a patient's general values. Patients and their relatives should always have the opportunity to ask

    Psychiatric advance directives (PADs) are legal documents that allow individuals to express their wishes for future psychiatric care and to authorize a legally appointed proxy to make decisions on their behalf during incapacitating crises. PADs are viewed as an alternative to the coercive interventions that sometimes accompany mental health crises for people with mental illness. Insofar as coercive interventions can abridge clients' autonomy and self-determination--values supported by the NASW Code of Ethics--social workers have a vested interest in finding ways to reduce coercion and increase autonomy and self-determination in their practice. However, PADs are also viewed as having the potential to positively affect a variety of other clinical outcomes, including, but not limited to, treatment engagement, treatment satisfaction, and working alliance. This article reviews the clinical and legal history of PADs and empirical evidence for their implementation and effectiveness. Despite what should be an inherent interest in PADs and the fact that laws authorizing PADs have proliferated in the past decade, there is little theoretical or empirical research on PADS in the social work literature.

    A state-of-the-art report is presented on recent progress in selected areas of myodynamics, but also on problems that severely hamper the further development of the discipline. Significant advances have been made in elucidating the force-producing interaction between actin and the myosin-S1-subunit, including the localization of the most probable molecular site of power stroke initiation. Concerning the architecture of the myostructures, strong experimental evidence has accumulated for numerous intra-, inter-, and extramuscular pathways for lateral force transmission in addition to the serial sarcomere-to-sarcomere myotendinous path. It is shown that contemporary muscle models are inadequate in most respects and lag far behind the requirements an appropriate myodynamic model should fulfil. A similar comment applies to the current approaches designed to solve the myoskeletal indeterminacy problem. These formulations neglect myodynamic properties and do not allow for the implementation of biologically realistic objective functions. The solutions currently obtained are highly unsatisfactory. New research directions to rectify these situations are suggested, also with regard to the identification of subject-specific myodynamic parameters. PMID:12435541

    HIV/AIDS is a leading cause of mortality and morbidity worldwide. In spite of successful interventions and treatment protocols, an HIV vaccine would be the ultimate prevention and control strategy. Ever since identification of HIV/AIDS, there have been meticulous efforts for vaccine development. The specific aim of this paper is to review recent vaccine efficacy trials and associated advancements and discuss the current challenges and future directions. Recombinant DNA technologies greatly facilitated development of many viral products which were later incorporated into vectors for effective vaccines. Over the years, a number of scientific approaches have gained popularity and include the induction of neutralizing antibodies in late 1980s, induction of CD8 T cell in early 1990s, and combination approaches currently. Scientists have hypothesized that stimulation of right sequences of somatic hypermutations could induce broadly reactive neutralizing antibodies (bnAbs) capable of effective neutralization and viral elimination. Studies have shown that a number of host and viral factors affect these processes. Similarly, eliciting specific CD8 T cells immune responses through DNA vaccines hold future promises. In summary, future studies should focus on the continuous fight between host immune responses and ever-evasive viral factors for effective vaccines. PMID:26579546

Ultra-high efficiency solar cells fabricated from gallium arsenide (GaAs) and its ternary alloys like gallium indium phosphide (GaInP2) are finding applications in space technology. Enormous progress has also been made on various thin-film solar cell technologies, which offer the promise for substantially reducing the cost of PV systems. Some of the leading contenders are amorphous and polycrystalline silicon, compound semiconductor thin films such as copper indium diselenide (CuInSe2) based alloys, and cadmium telluride (CdTe) thin films. Exciting new developments are happening in the use of nano-particle semiconductor materials like titanium dioxide (TiO2) for low-cost PV devices. Intense research on these and other materials and devices is making a strong impact on the technology.

    In cancer patients, decision-making process is crucial and patient's involvement is described as a central component. In 2005, a new tool appears to convey patient's opinion even if he is not able to communicate anymore: advanced directives (AD). Unfortunately, their documentation is marginal. The objective of this study was to investigate nurses' and physicians' representations towards AD. A questionnaire had been sent to hospitals, public health facilities and liberal practitioners during February 2012. We collected responses from 42/251 physicians (17 %) and 80/198 nurses (40 %). Sixty percent of participants reported that they were not familiar with the legislative framework for AD. For physicians, main barriers were patient cognitive impairment (P = 0.004) and lack of information on the clinical situation (P = 0.004). For nurses, difficulties were toward end of life and prognosis discussion (P = 0.002), clinical situation evolution since AD documentation (P = 0.008), time frame for AD application (P < 0.001) and the fact that final decision is made by physician alone (P = 0.015). AD should be part of a good medical practice and literature has highlighted the benefit of AD on patient's quality of life. End of life discussion therefore requires dedicated time and specific training for physicians and nurses to improve the rate of patients with AD. PMID:24077035

    2009-01-01

    The concept of reversing the characteristics of differentiated tissues to pluripotency through reprogramming was introduced over 50 years ago in the first somatic cell nuclear transfer (SCNT) experiments. More recently, direct reprogramming of differentiated somatic cells by gene transfer of a small number of defined transcription factors has been shown to yield cells that are indistinguishable from inner cell mass–derived embryonic stem (ES) cells. These cells, termed induced pluripotent stem (iPS) cells, offer exciting possibilities for studying mechanism of pluripotency, establishing models for disease-specific investigations, and enabling future applications in regenerative medicine. In this review, we discuss the basic foundation of reestablishing pluripotency and recent progress toward enhancing the efficiency and safety of the process through optimization of the reprogramming factor combination, identification of small molecules that augment efficiency, and assessment of distinct target cells in reprogramming efficiency. We also highlight recent advances that eliminate stable genetic modification from the reprogramming process, and summarize preclinical models that provide proof-of-concept for ES/iPS cell-based regenerative medicine.

    Because older adults are at high risk for hospitalization and potential decisional incapacity, advance directives are important components of pre-hospital advanced care planning, as they document individual preferences for future medical care. The prevalence of pre-hospital advance directive completion in 450 critically ill older adults requiring mechanical ventilation from two Mid-Atlantic hospitals is described, and demographic and clinical predictors of pre-hospital advance directive completion are explored. The overall advance directive completion rate was 42.4%, with those in older age groups (75 to 84 years and 85 and older) having approximately two times the odds of completion. No significant differences in the likelihood of advance directive completion were noted by sex, race, or admitting diagnosis. The relatively low prevalence of advance directive completion among older adults with critical illness and high mortality rate (24%) suggest a need for greater awareness and education.

    Advanced directional solidification methods have been used to produce large (>15 cm length) castings of Alnico permanent magnets with highly oriented columnar microstructures. In combination with subsequent thermomagnetic and draw thermal treatment, this method was used to enable the high coercivity, high-Titanium Alnico composition of 39% Co, 29.5% Fe, 14% Ni, 7.5% Ti, 7% Al, 3% Cu (wt%) to have an intrinsic coercivity (Hci) of 2.0 kOe, a remanence (Br) of 10.2 kG, and an energy product (BH)max of 10.9 MGOe. These properties compare favorably to typical properties for the commercial Alnico 9. Directional solidification of higher Ti compositions yieldedmore » anisotropic columnar grained microstructures if high heat extraction rates through the mold surface of at least 200 kW/m2 were attained. This was achieved through the use of a thin walled (5 mm thick) high thermal conductivity SiC shell mold extracted from a molten Sn bath at a withdrawal rate of at least 200 mm/h. However, higher Ti compositions did not result in further increases in magnet performance. Images of the microstructures collected by scanning electron microscopy (SEM) reveal a majority α phase with inclusions of secondary αγ phase. Transmission electron microscopy (TEM) reveals that the α phase has a spinodally decomposed microstructure of FeCo-rich needles in a NiAl-rich matrix. In the 7.5% Ti composition the diameter distribution of the FeCo needles was bimodal with the majority having diameters of approximately 50 nm with a small fraction having diameters of approximately 10 nm. The needles formed a mosaic pattern and were elongated along one <001> crystal direction (parallel to the field used during magnetic annealing). Cu precipitates were observed between the needles. Regions of abnormal spinodal morphology appeared to correlate with secondary phase precipitates. The presence of these abnormalities did not prevent the material from displaying superior magnetic properties in the 7.5% Ti

    Advanced directional solidification methods have been used to produce large (>15 cm length) castings of Alnico permanent magnets with highly oriented columnar microstructures. In combination with subsequent thermomagnetic and draw thermal treatment, this method was used to enable the high coercivity, high-Titanium Alnico composition of 39% Co, 29.5% Fe, 14% Ni, 7.5% Ti, 7% Al, 3% Cu (wt%) to have an intrinsic coercivity (Hci) of 2.0 kOe, a remanence (Br) of 10.2 kG, and an energy product (BH)max of 10.9 MGOe. These properties compare favorably to typical properties for the commercial Alnico 9. Directional solidification of higher Ti compositions yielded anisotropic columnar grained microstructures if high heat extraction rates through the mold surface of at least 200 kW/m2 were attained. This was achieved through the use of a thin walled (5 mm thick) high thermal conductivity SiC shell mold extracted from a molten Sn bath at a withdrawal rate of at least 200 mm/h. However, higher Ti compositions did not result in further increases in magnet performance. Images of the microstructures collected by scanning electron microscopy (SEM) reveal a majority α phase with inclusions of secondary αγ phase. Transmission electron microscopy (TEM) reveals that the α phase has a spinodally decomposed microstructure of FeCo-rich needles in a NiAl-rich matrix. In the 7.5% Ti composition the diameter distribution of the FeCo needles was bimodal with the majority having diameters of approximately 50 nm with a small fraction having diameters of approximately 10 nm. The needles formed a mosaic pattern and were elongated along one <001> crystal direction (parallel to the field used during magnetic annealing). Cu precipitates were observed between the needles. Regions of abnormal spinodal morphology appeared to correlate with secondary phase precipitates. The presence of these abnormalities did not prevent the material from displaying superior magnetic properties in the 7.5% Ti

    Exploration Life Support (ELS) Project, under the Exploration Technology Development Program, has recently been initiated to perform directed life support technology development in support of Constellation and the Crew Exploration Vehicle (CEV). ELS) has replaced ALS, with several major differences. Thermal Control Systems have been separated into a new stand alone project (Thermal Systems for Exploration Missions). Tasks in Advanced Food Technology have been relocated to the Human Research Program. Tasks in a new discipline area, Habitation Engineering, have been added. Research and technology development for capabilities required for longer duration stays on the Moon and Mars, including bioregenerative system, have been deferred.

    Perception of health and disease, pain and suffering, quality of life, personal relationships, privacy and intimacy, culture and social values, can now be stated in a written document, by way of a living will, giving legal legitimacy to each patient's way of being and understanding life, to be used when the subject cannot express it by him/herself. In this way, the patients will participate in the therapeutic process and will incorporate their desires and decisions through the Informed Consent and the Advanced Directives Document (ADD). Both documents translate and indicate how to treat and care for a patient who will progressively lose his/her cognitive faculties and others will decided for him/her, in the case of dementias. The basis of ADD is respect and promotion of the patient's autonomy, prolonging his/her right to decide in the stages in which he/she cannot do it. It consists in some instructions or orientations for the patient to be cared for in a certain way, according to his/her will. To this effect, a representative will be named who will act in the subject's name and who will help to interpret and make decisions when the patient cannot. Specifically, in Alzheimer's disease, ADD allows the patient to decide, in full lucidity, freedom and autonomy, how to live a progressive and irreversible disease. Explicit mention can be made to the will of making his/her disease known publically or not, the care of its aspect, privacy, type of care, whether institutionalized or home care, limitation of visits, treatment intensity and prolongation, palliative cares, donation of biological samples, participation in drug clinical trials.

    The Patient Self-Determination Act was created to enhance awareness and use of advance directives. Several states also have created registries where the advance directives can be easily retrieved when needed. Quick retrieval is especially important in critical access hospitals where patients are often transferred to other facilities. This article describes an innovative project designed to improve the advance directives request and retrieval process on admission to a critical access hospital. PMID:26681498

    OBJECTIVE: To assess whether advance directives influence resource use by hospitalized patients. DATA SOURCES: A systematic search of computerized medical databases, reference lists from relevant articles, and personal files was conducted to identify studies examining the association between advance directives and resource use. STUDY SELECTION: Primary studies assessing the effect of advance directives on hospital resource use were selected if they had a clear quantitative measure of hospital resource use, hospitalized patients as a study population, a control group for comparison, and a description of the advance directive being studied. Data on the following topics were abstracted from studies meeting inclusion criteria: study methods and design, resource use, source of financial data, description of advance directive, population size and composition, length of assessment. SYNTHESIS: Six studies met inclusion criteria. Three retrospective studies showed significant reductions in resource use associated with documentation of advance directives while three prospective studies (two randomized, one not randomized) showed no association between advance directives and reduced resource use. Studies were limited to narrowly defined patient populations in US tertiary care hospitals. CONCLUSIONS: Little evidence supports the hypothesis that advance directives reduce resource use by hospitalized patients. Some retrospective studies have shown savings, but their conclusions are weakened by shortcomings in study design. Prospective trials, which have better experimental methods, have demonstrated no evidence of cost savings with the use of advance directives. PMID:10540700

    Objectives. To investigate the preferences of ACP and healthcare autonomy in community-dwelling older Chinese adults. Methods. A community-based cross-sectional study was conducted with older adults living in the residential estate of Chaoyang District, Beijing. Results. 900 residents were enrolled. 80.9% of them wanted to hear the truth regarding their own condition from the physician; 52.4% preferred to make their own healthcare decisions. Only 8.9% of them preferred to endure life-prolonging interventions when faced with irreversible conditions. 78.3% of the respondents had not heard of an ACP; only 39.4% preferred to document in an ACP. Respondents with higher education had significantly higher proportion of having heard of an ACP, as well as preferring to document in an ACP, compared to those with lower education. Those aged <70 years had higher proportion of having heard of an ACP, as well as refusing life-prolonging interventions when faced with irreversible conditions, compared to those aged ≥70 years. Conclusions. Although the majority of community-dwelling older Chinese adults appeared to have healthcare autonomy and refuse life-prolonging interventions in terms of end-of-life care, a low level of “Planning ahead” awareness and preference was apparent. Age and education level may be the influential factors. PMID:26858955

    The provision of optimum care for the ageing population is dependent on the understanding of their views and values on end of life issues. A qualitative descriptive study was conducted to describe views of elderly Malaysians on Advanced Care Planning (henceforth ACP) and Advanced Directives (henceforth AD), and explore factors influencing these views. Fifteen elderly subjects with ages ranging from 65 to 83 years, representing different ethnic and religious groups in Malaysia were selected for in-depth interviews guided by a questionnaire. Five core themes were extracted from the interviews: 1) Considering the future 2) Contingency plans for future illnesses 3) Attitudes towards life prolonging treatment procedures 4) Doctor-patient relationships and 5) Influence of religion on decisions related to future illness. Despite the lack of knowledge on ACP and AD, older respondents were very receptive to their concept. Although the majority agreed on the importance of planning for future medical management and having open discussion on end of life issues with their doctor, they felt it unnecessary to make a formal written AD. Most felt that the future was best left to fate or God, and none had made any contingency plan for severe future illnesses citing religion as reason for this view. Cardiopulmonary resuscitation, mechanical ventilation and dialysis were considered by most to be invasive life prolonging treatments. We suggest that doctors initiate discussions on end of life care with every older patient and their family so as to promote awareness and introduce the concept of ACP/AD to a Malaysian setting.

    Context Advance care planning (ACP) has focused on documenting life-sustaining treatment preferences in advance directives (ADs). ADs alone may be insufficient to prepare diverse patients and surrogates for complex medical decisions. Objectives To understand what steps best prepare patients and surrogates for decision making. Methods We conducted 13 English/Spanish focus groups with participants from a Veterans Affairs and county hospital and the community. Seven groups included patients (n=38) aged ≥65 years, who reported making serious medical decisions. Six separate groups included surrogates (n=31), aged ≥18 years, who made decisions for others. Semi-structured focus groups asked what activities best prepared participants for decision making. Two investigators independently coded data and performed thematic content analysis. Disputes were resolved by consensus. Results Mean±SD patient age was 78±8 years and 61% were non-white. Mean±SD surrogate age was 57±10 years and 91% were non-white. Qualitative analysis identified four overarching themes about how to best prepare for decision making: 1) identify values based on past experiences and quality of life, 2) choose surrogates wisely and verify they understand their role, 3) decide whether to grant leeway in surrogate decision making, and 4) inform other family and friends of one's wishes to prevent conflict. Conclusion Beyond ADs, patients and surrogates recommend several additional steps to prepare for medical decision making including using past experiences to identify values, verifying the surrogate understands their role, deciding whether to grant surrogates leeway, and informing other family and friends of one's wishes. Future ACP interventions should consider incorporating these additional ACP activities. PMID:23200188

    Fluorescent proteins have become indispensable imaging tools for biomedical research. continuing progress in fluorescence imaging, however, requires probes with additional colors and properties optimized for emerging techniques. Here we summarize strategies for development of red-shifted fluorescent proteins. We discuss possibilities for knowledge-based rational design based on the photochemistry of fluorescent proteins and the position of the chromophore in protein structure. We consider advances in library design by mutagenesis, protein expression systems and instrumentation for high-throughput screening that should yield improved fluorescent proteins for advanced imaging applications.

    Recent advances in the selective deprotometallation of aromatic reagents using alkali metal cuprates are reported. The ability of these synergic bases to effect deprotonation under the influence of a directing group is explored in the context of achieving new and more efficient organic transformations whilst encouraging greater ancillary group tolerance by the base. Developments in our understanding of the structural chemistry of alkali metal cuprates are reported, with both Gilman cuprates of the type R2CuLi and Lipshutz and related cuprates of the type R2Cu(X)Li2 (X = inorganic anion) elucidated and rationalised in terms of ligand sterics. The generation of new types of cuprate motif are introduced through the development of adducts between different classes of cuprate. The use of DFT methods to interrogate the mechanistic pathways towards deprotonative metallation is described. Theoretical modelling of in situ rearrangements undergone by the cuprate base are discussed, with a view to understanding the relationship between R2CuLi and R2Cu(X)Li2, their interconversion and the implications of this for cuprate reactivity. The advent of a new class of adduct between different cuprate types is developed and interpreted in terms of the options for expelling LiX from R2Cu(X)Li2. Applications in the field of medicinal chemistry and (hetero)arene derivatization are explored. PMID:24919957

    2000-01-01

    Reviewed in this article are selected recent advances and future challenges for psychiatric epidemiology. Major advances in descriptive psychiatric epidemiology in recent years include the development of reliable and valid fully structured diagnostic interviews, the implementation of parallel cross-national surveys of the prevalences and correlates of mental disorders, and the initiation of research in clinical epidemiology. Remaining challenges include the refinement of diagnostic categories and criteria, recognition and evaluation of systematic underreporting bias in surveys of mental disorders, creation and use of accurate assessment tools for studying disorders of children, adolescents, the elderly, and people in less developed countries, and setting up systems to carry out small area estimations for needs assessment and programme planning. Advances in analytical and experimental epidemiology have been more modest. A major challenge is for psychiatric epidemiologists to increase the relevance of their analytical research to their colleagues in preventative psychiatry as well as to social policy analysts. Another challenge is to develop interventions aimed at increasing the proportion of people with mental disorders who receive treatment. Despite encouraging advances, much work still needs to be conducted before psychiatric epidemiology can realize its potential to improve the mental health of populations. PMID:10885165

    An innovative Virginia health care law enables competent adults with serious mental illness to plan for treatment during incapacitating crises using an integrated advance directive with no legal distinction between psychiatric or other causes of decisional incapacity. This article reports results of a survey of 460 individuals in five stakeholder groups during the initial period of the law's implementation. All respondents held favorable views of advance directives for mental health care. Identified barriers to completing and using advance directives varied by group. We conclude that relevant stakeholders support implementation of advance directives for mental health, but level of baseline knowledge and perception of barriers vary. A multi-pronged approach will be needed to achieve successful implementation of advance directives for mental health. PMID:22240937

    1997-09-01

    This article evaluates the potential role of advance directives outside of their original North American context. In order to do this, the article first analyses the historical process which has promoted advance directives in recent years. Next, it brings to light certain presuppositions which have given them force: atomistic individualism, contractualism, consumerism and entrepreneurialism, pluralism, proceduralism, and "American moralism." The article next studies certain European cultural peculiarities which could affect advance directives: the importance of virtue versus rights, stoicism versus consumerist utilitarianism, rationalism verus empiricism, statism versus citizens' initiative, and justice versus autonomy. The article concludes by recognising that autonomy has a transcultural value, although it must be balanced with other principles. Advance Directives can have a function in certain cases. But it does not seem adequate to delegate to advance directives more and more medical decisions, and to make them more binding everyday. It is indispensable to develop other decision-making criteria.

  18. Advanced or advancing nursing practice: what is the future direction for nursing?

    PubMed

    Gray, Alastair

    Advanced nursing practice roles have emerged over the last 25 years in response to two major challenges: first, the significant reduction in available doctors; and, second, the rise in numbers of patients with complex health needs. It is suggested that, with a major drive to respond to the first problem, with its emphasis on the development of medical skills, the development of advanced nursing practice (which has the potential to have a significant impact on the second challenge of the rise in long-term conditions) has very much taken second place. Moreover, advanced nursing practice roles have become so medically focused that not only is advanced nursing practice not evident, but neither are the recognised sub-roles that are fundamental to advancing practice. These include innovation, education, research and clinical leadership. This article argues that in the current climate it is essential that advanced nurse practitioners not only demonstrate advanced practice, but also actively embrace the concept of 'advancing' nursing practice as the dominant feature of new roles.

    In the Advance Coal Liquefaction Concept Proposal (ACLCP) carbon monoxide (CO) and water have been proposed as the primary reagents in the pretreatment process. The main objective of this project is to develop a methodology for pretreating coal under mild conditions based on a combination of existing processes which have shown great promise in liquefaction, extraction and pyrolysis studies. The aim of this pretreatment process is to partially depolymerise the coal, eliminate oxygen and diminish the propensity for retograde reactions during subsequent liquefaction. The desirable outcome of the CO pretreatment step should be: (1) enhanced liquefaction activity and/or selectivity toward products of higher quality due to chemical modification of the coal structure; (2) cleaner downstream products; (3) overall improvement in operability and process economics.

    Melanoma is one of the most aggressive cancers and is responsible for a large proportion of skin cancer-related deaths. The recent development of novel immunotherapeutic approaches has led to great advances in melanoma therapy. Because melanoma cells often express tumor-specific neo-antigens, significant therapeutic effects are mediated via immunotherapy-induced activation of cytotoxic T lymphocytes (CTLs); however, the effects depend on the immune status of the patient. At present, various immunotherapies have been approved and new clinical trials are progressing. These immunotherapies act in several ways, including CTL brake release, induction of CTL activation, transfer of CTLs, and modification of the tumor microenvironment to facilitate CTL activation. In the near future, patient-tailored immunotherapies and combination therapies are expected. In addition, it is important to monitor the status of the patient's immune response when selecting the most effective immunotherapy strategy. PMID:27302423

    Integration of innovative steps into new advanced processes have the potential to reduce costs for producing liquid fuels. In this program, objective is to develop a new approach to liquefaction that generates an all distillate product slate at a reduced cost of about US$25/barrel of crude oil equivalent. A Counterflow Reactor was developed in cooperation with GfK mbH, Germany. Advantages are low hydrogen recycle rates and low feed preheating requirements. Coal/heavy oil slurry is injected into the top of the reactor while the recycle gas and make up hydrogen is introduced into the bottom; hydrogenation products are withdrawn from the top. PU study resulted in distillable oil yields up to 74 wt % on feed (dry ash free) from coprocessing feed slurries containing 40 wt % Vesta subbituminous coal and 60 wt % Cold Lake heavy vacuum tower bottoms. Technologies developed separately by CED and ARC were combined. A 1-kg/hr integrated continuous flow bench scale unit was constructed at the ARC site in Devon, Alberta, based on modifications to a unit at Nisku, Alberta (the modified unit was used in the preliminary economic evaluation).

    Ion nitriding and carburizing are plasma activated thermodynamic processes for the production of case hardened surface layers not only for ferrous materials, but also for an increasing number of nonferrous metals. When the treatment variables are properly controlled, the use of nitrogenous or carbonaceous glow discharge medium offers great flexibility in tailoring surface/near-surface properties independently of the bulk properties. The ion nitriding process has reached a high level of maturity and has gained wide industrial acceptance, while the more recently introduced ion carburizing process is rapidly gaining industrial acceptance. The current status of plasma mass transfer mechanisms into the surface regarding the formation of compound and diffusion layers in ion nitriding and carbon build-up ion carburizing is reviewed. In addition, the recent developments in design and construction of advanced equipment for obtaining optimized and controlled case/core properties is summarized. Also, new developments and trends such as duplex plasma treatments and alternatives to dc diode nitriding are highlighted.

    Thermal barrier coatings will be more aggressively designed to protect gas turbine engine hot-section components in order to meet future engine higher fuel efficiency and lower emission goals. In this presentation, thermal barrier coating development considerations and performance will be emphasized. Advanced thermal barrier coatings have been developed using a multi-component defect clustering approach, and shown to have improved thermal stability and lower conductivity. The coating systems have been demonstrated for high temperature combustor applications. For thermal barrier coatings designed for turbine airfoil applications, further improved erosion and impact resistance are crucial for engine performance and durability. Erosion resistant thermal barrier coatings are being developed, with a current emphasis on the toughness improvements using a combined rare earth- and transition metal-oxide doping approach. The performance of the toughened thermal barrier coatings has been evaluated in burner rig and laser heat-flux rig simulated engine erosion and thermal gradient environments. The results have shown that the coating composition optimizations can effectively improve the erosion and impact resistance of the coating systems, while maintaining low thermal conductivity and cyclic durability. The erosion, impact and high heat-flux damage mechanisms of the thermal barrier coatings will also be described.

    2012-01-01

    Enzymatic hydrolysis of pre-treated lignocellulosic biomass is an ideal alternative to acid hydrolysis for bio-ethanol production, limited primarily by pre-treatment requirements and economic considerations arising from enzyme production costs and specific activities. The quest for cheaper and better enzymes has prompted years of bio-prospecting, strain optimization through genetic engineering, enzyme characterization for simple and complex lignocellulosic feedstock, and the development of pre-treatment strategies to mitigate inhibitory effects. The recent shift to systematic characterizations of de novo mixtures of purified proteins is a promising indicator of maturation within this field of study, facilitating progression towards feedstock assay-based rapid enzyme mixture optimization. It is imperative that international standards be developed to enable meaningful comparisons between these studies and the construction of a database of enzymatic activities and kinetics, aspects of which are explored here-in. Complementary efforts to improve the economic viability of enzymatic hydrolysis through process integration and reactor design are also considered, where membrane-confinement shows significant promise despite the associated technological challenges. Significant advancements in enzyme technology towards the economic conversion of lignocellulosic biomass should be expected within the next few years as systematic research in enzyme activities conforms to that of traditional reaction engineering.

    The purpose of this study is to provide a critical review and synthesis of theoretical and research literature documenting the impact of avoidance on healthcare behaviors, identify the factors that influence healthcare avoidance and delay in the adult population, and propose a direction for future research. The Theory of Reasoned Action, Theory of Planned Behavior, Theory of Care-Seeking Behavior, the Transtheoretical Model, and the Behavioral Model of Health Services Use/Utilization are utilized to elaborate on the context within which individual intention to engage in healthcare behaviors occurs. Research literature on the concept of healthcare avoidance obtained by using computerized searches of CINAHL, MEDLINE, PSYCH INFO, and HAPI databases, from 1995 to 2007, were reviewed. Studies were organized by professional disciplines. Healthcare avoidance is a common and highly variable experience. Multiple administrative, demographic, personal, and provider factors are related to healthcare avoidance, for example, distrust of providers and/or the science community, health beliefs, insurance status, or socioeconomic/income level. Although the concept is recognized by multiple disciplines, limited research studies address its impact on healthcare decision making. More systematic research is needed to determine correlates of healthcare avoidance. Such studies will help investigators identify patients at risk for avoidant behaviors and provide the basis for health-promoting interventions. Methodological challenges include identification of characteristics of individuals and environments that hinder healthcare behaviors, as well as, the complexity of measuring healthcare avoidance. Studies need to systematically explore the influence of avoidance behaviors on specific healthcare populations at risk. PMID:18758277

    Background Advance directive law may compromise the clinical effectiveness of advance directives. Purpose To identify unintended legal consequences of advance directive law that may prevent patients from communicating end-of-life preferences. Data Sources Advance directive legal statutes for all 50 U.S. states and the District of Columbia and English-language searches of LexisNexis, Westlaw, and MEDLINE from 1966 to August 2010. Study Selection Two independent reviewers selected 51 advance directive statutes and 20 articles. Three independent legal reviewers selected 105 legal proceedings. Data Extraction Two reviewers independently assessed data sources and used critical content analysis to determine legal barriers to the clinical effectiveness of advance directives. Disagreements were resolved by consensus. Data Synthesis Legal and content-related barriers included poor readability (that is, laws in all states were written above a 12th-grade reading level), health care agent or surrogate restrictions (for example, 40 states did not include same-sex or domestic partners as default surrogates), and execution requirements needed to make forms legally valid (for example, 35 states did not allow oral advance directives, and 48 states required witness signatures, a notary public, or both). Vulnerable populations most likely to be affected by these barriers included patients with limited literacy, limited English proficiency, or both who cannot read or execute advance directives; same-sex or domestic partners who may be without legally valid and trusted surrogates; and unbefriended, institutionalized, or homeless patients who may be without witnesses and suitable surrogates. Limitation Only appellate-level legal cases were available, which may have excluded relevant cases. Conclusion Unintended negative consequences of advance directive legal restrictions may prevent all patients, and particularly vulnerable patients, from making and communicating their end

    An interest in biodiesel as an alternative fuel for diesel engines has been increasing because of the issue of petroleum depletion and environmental concerns related to massive carbon dioxide emissions. Researchers are strongly driven to pursue the next generation of vegetable oil-based biodiesel. Oleaginous microalgae are considered to be a promising alternative oil source. To commercialize microalgal biodiesel, cost reductions in oil extraction and downstream biodiesel conversion are stressed. Herein, starting from an investigation of oil extraction from wet microalgae, a review is conducted of transesterification using enzymes, homogeneous and heterogeneous catalysts, and yield enhancement by ultrasound, microwave, and supercritical process. In particular, there is a focus on direct transesterification as a simple and energy efficient process that omits a separate oil extraction step and utilizes wet microalgal biomass; however, it is still necessary to consider issues such as the purification of microalgal oils and upgrading of biodiesel properties.

    Because of the deep interpersonal significance of decisions made at the end of life, it is not surprising that religion has played an important role in patient and family decision making. Specific religious concerns about death and dying have led to religious advance directives. Advance directives offer a case study of models of interaction between religious communities and secular institutions. This paper examines why such directives have been created and how they may affect health care decisions. An analysis of their strengths and weaknesses concludes that specific religious instructions are unnecessary in written directives and may undermine both the religious and health care goals of patients.

    Engineering has been playing an important role in serving and advancing healthcare. The term "Healthcare Engineering" has been used by professional societies, universities, scientific authors, and the healthcare industry for decades. However, the definition of "Healthcare Engineering" remains ambiguous. The purpose of this position paper is to present a definition of Healthcare Engineering as an academic discipline, an area of research, a field of specialty, and a profession. Healthcare Engineering is defined in terms of what it is, who performs it, where it is performed, and how it is performed, including its purpose, scope, topics, synergy, education/training, contributions, and prospects.

  13. Inapplicability of advance directives in a paternalistic setting: the case of a post-communist health system

    PubMed Central

    2011-01-01

    Background The Albanian medical system and Albanian health legislation have adopted a paternalistic position with regard to individual decision making. This reflects the practices of a not-so-remote past when state-run facilities and a totalitarian philosophy of medical care were politically imposed. Because of this history, advance directives concerning treatment refusal and do-not-resuscitate decisions are still extremely uncommon in Albania. Medical teams cannot abstain from intervening even when the patient explicitly and repeatedly solicits therapeutic abstinence. The Albanian law on health care has no provisions regarding limits or withdrawal of treatment. This restricts the individual's healthcare choices. Discussion The question of 'medically futile' interventions and pointless life-prolonging treatment has been discussed by several authors. Dutch physicians call such interventions 'medisch zinloos' (senseless), and the Netherlands, as one of the first states to legislate on end-of-life situations, actually regulates such issues through appropriate laws. In contrast, leaving an 'advance directive' is not a viable option for Albanian ailing individuals of advanced age. Verbal requests are provided during periods of mental competence, but unfortunately such instructions are rarely taken seriously, and none of them has ever been upheld in a legal or other official forum. Summary End-of-life decisions, treatment refusal and do-not-resuscitate policies are hazardous options in Albania, from the legal point of view. Complying with them involves significant risk on the part of the physician. Culturally, the application of such instructions is influenced from a mixture of religious beliefs, death coping-behaviors and an immense confusion concerning the role of proxies as decision-makers. Nevertheless, Albanian tradition is familiar with the notion of 'amanet', a sort of living will that mainly deals the property and inheritance issues. Such living wills, verbally

    The U.S. Geological Survey is developing a directional borehole radar (DBOR) tool for mapping fractures, lithologic changes, and underground utility and void detection. An important part of the development of the DBOR tool is data analysis and visualization, with the aim of making the software graphical user interface (GUI) intuitive and easy to use. The DBOR software system consists of a suite of signal and image processing routines written in Research Systems' Interactive Data Language (IDL). The software also serves as a front-end to many widely accepted Colorado School of Mines Center for Wave Phenomena (CWP) Seismic UNIX (SU) algorithms (Cohen and Stockwell, 2001). Although the SU collection runs natively in a UNIX environment, our system seamlessly emulates a UNIX session within a widely used PC operating system (MicroSoft Windows) using GNU tools (Noer, 1998). Examples are presented of laboratory data acquired with the prototype tool from two different experimental settings. The first experiment imaged plastic pipes in a macro-scale sand tank. The second experiment monitored the progress of an invasion front resulting from oil injection. Finally, challenges to further development and planned future work are discussed.

  15. Advancing the Field Elder Abuse: Future Directions and Policy Implications

    PubMed Central

    Dong, XinQi

    2012-01-01

    Elder abuse, sometime called elder mistreatment or elder maltreatment, includes psychological, physical, and sexual abuse, neglect (caregiver neglect and self-neglect), and financial exploitation. Evidence suggests that 1 out of 10 older adult experiences some form of elder abuse, and only 1 of out 25 cases are actually reported to social services agencies. At the same time, elder abuse is associated with significant morbidity and premature mortality. Despite these findings, there is a great paucity in research, practice, and policy dealing with the pervasive issues of elder abuse. Through my experiences as a American Political Sciences Association Congressional Policy Fellow/Health and Aging Policy Fellow working with Administration on Community Living (ACL) (Previously known at Administration on Aging (AoA)) for the last two years, I will describe the major functions of the ACL; and highlight on two major pieces of federal legislation: The Older Americans Act (OAA) and the Elder Justice Act (EJA). Moreover, I will highlight major research gaps and future policy relevant research directions for the field of elder abuse. PMID:23110488

    2015-01-01

    To image cold exoplanets directly in visible light, an instrument on a telescope needs to suppress starlight by about 9 orders of magnitude at small separations from the star. A coronagraph changes the point spread function to create regions of high contrast where exoplanets or disks can be seen. Aberrations on the optics degrade the contrast by several orders of magnitude, so all high-contrast imaging systems incorporate one or more deformable mirrors (DMs) to recover regions of high contrast. With a coronagraphic instrument planned for the WFIRST-AFTA space telescope, there is a pressing need for faster, more robust estimation and control schemes for the DMs. Non-common path aberrations limit conventional phase conjugation schemes to medium star-to-planet contrast ratios of about 1e-6. High-contrast imaging requires estimation and control of both phase and amplitude in the same beam path as the science camera. Field estimation is a challenge since only intensity is measured; the most common approach, including that planned for WFIRST-AFTA, is to use DMs to create diversity, via pairs of small probe shapes, thereby allowing disambiguation of the electric field. Most implementations of DM Diversity require at least five images per electric field estimate and require narrowband measurements. This paper describes our new estimation algorithms that improve the speed (by using fewer images) and bandwidth of focal plane wavefront estimation. For narrowband estimation, we are testing nonlinear, recursive algorithms such as an iterative extended Kalman filter (IEKF) to use three images each iteration and build better, more robust estimates. We are also exploring the use of broadband estimation without the need for narrowband sub-filters and measurements. Here we present simulations of these algorithms with realistic noise and small signals to show how they might perform for WFIRST-AFTA. Once validated in simulations, we will test these algorithms experimentally in

  17. Wayfinding in Healthcare Facilities: Contributions from Environmental Psychology

    PubMed Central

    Devlin, Ann Sloan

    2014-01-01

    The ability to successfully navigate in healthcare facilities is an important goal for patients, visitors, and staff. Despite the fundamental nature of such behavior, it is not infrequent for planners to consider wayfinding only after the fact, once the building or building complex is complete. This review argues that more recognition is needed for the pivotal role of wayfinding in healthcare facilities. First, to provide context, the review presents a brief overview of the relationship between environmental psychology and healthcare facility design. Then, the core of the article covers advances in wayfinding research with an emphasis on healthcare environments, including the roles of plan configuration and manifest cues, technology, and user characteristics. Plan configuration and manifest cues, which appeared early on in wayfinding research, continue to play a role in wayfinding success and should inform design decisions. Such considerations are joined by emerging technologies (e.g., mobile applications, virtual reality, and computational models of wayfinding) as a way to both enhance our theoretical knowledge of wayfinding and advance its applications for users. Among the users discussed here are those with cognitive and/or visual challenges (e.g., Down syndrome, age-related decrements such as dementia, and limitations of vision). In addition, research on the role of cross-cultural comprehension and the effort to develop a system of universal healthcare symbols is included. The article concludes with a summary of the status of these advances and directions for future research. PMID:25431446

    Advances in wireless technology give pace to the rapid development of mobile applications. The coming mobile revolution will bring dramatic and fundamental changes to our daily life. It will influence the way we live, the way we do things, and the way we take care of our health. For the healthcare industry, mobile applications provide a new frontier in offering better care and services to patients, and a more flexible and mobile way of communicating with suppliers and patients. Mobile applications will provide important real time data for patients, physicians, insurers, and suppliers. In addition, it will revolutionalize the way information is managed in the healthcare industry and redefine the doctor - patient communication. This paper discusses different aspects of mobile healthcare. Specifically, it presents mobile applications in healthcare, and discusses possible challenges facing the development of mobile applications. Obstacles in developing mobile healthcare applications include mobile device limitations, wireless networking problems, infrastructure constraints, security concerns, and user distrust. Research issues in resolving or alleviating these problems are also discussed in the paper. PMID:16777784

  1. Data mining applications in healthcare.

    PubMed

    Koh, Hian Chye; Tan, Gerald

    2005-01-01

    Data mining has been used intensively and extensively by many organizations. In healthcare, data mining is becoming increasingly popular, if not increasingly essential. Data mining applications can greatly benefit all parties involved in the healthcare industry. For example, data mining can help healthcare insurers detect fraud and abuse, healthcare organizations make customer relationship management decisions, physicians identify effective treatments and best practices, and patients receive better and more affordable healthcare services. The huge amounts of data generated by healthcare transactions are too complex and voluminous to be processed and analyzed by traditional methods. Data mining provides the methodology and technology to transform these mounds of data into useful information for decision making. This article explores data mining applications in healthcare. In particular, it discusses data mining and its applications within healthcare in major areas such as the evaluation of treatment effectiveness, management of healthcare, customer relationship management, and the detection of fraud and abuse. It also gives an illustrative example of a healthcare data mining application involving the identification of risk factors associated with the onset of diabetes. Finally, the article highlights the limitations of data mining and discusses some future directions. PMID:15869215

    Many studies have investigated the effectiveness of interventions in promoting advance directives (ADs) but there is uncertainty as to what works best, and in whom. We conducted a systematic review of the evidence in this regard, using both classical meta-analysis approaches and multi-level analyses. Eleven databases were searched for relevant reports published through March 2007. All prospective studies were eligible, whether involving a single group or several and, in the latter case, regardless of the allocation mechanism. Outcomes included formal and informal ADs assessed by chart review or self-report. Heterogeneous sets of outcomes were pooled under a random-effects model. The search yielded 55 studies, half of which targeted outpatients. Most groups of subjects were educated in a single session led by one healthcare professional. Outcomes were measured within six months of the intervention in 73% of cases. The largest set of single-arm studies yielded an overall AD completion rate of 45.6%. Across randomized trials, the largest pooled odds ratio was 4.0, decreasing to 2.6 when all comparative studies were included. Multi-variable analyses identified the provision of oral information over multiple sessions as the most successful intervention. This was true regardless of the target population. These findings support the effectiveness of educational interventions in increasing the formulation of ADs and provide practical advice on how best to achieve this goal. PMID:18644667

    Context Advance directives (ADs) are expected to improve patients’ end-of-life outcomes, but retrospective analyses, surrogate recall of patients’ preferences, and selection bias have hampered efforts to determine ADs’ effects on patient outcomes. Objectives To examine associations among ADs, quality of life, and estimated costs of care in the week before death. Methods We used prospective data from interviews of 336 patients with advanced cancer and their caregivers, and analyzed patient baseline interview and caregiver and provider post-mortem evaluation data from the Coping with Cancer study. Cost estimates were from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample and published Medicare payment rates and cost estimates. Outcomes were quality of life (range 0-10) and estimated costs of care received in the week before death. Because patient end-of-life care preferences influence both AD completion and care use, analyses were stratified by preferences regarding heroic endof-life measures (everything possible to remain alive). Results Most patients did not want heroic measures (76%). Do-not-resuscitate (DNR) orders were associated with higher quality of life (β=0.75, standard error=0.30, P=0.01) across the entire sample. There were no statistically significant relationships between DNR orders and outcomes among patients when we stratified by patient preference, or between living wills/durable powers of attorney and outcomes in any of the patient groups. Conclusion The associations between DNR orders and better quality of life in the week before death indicate that documenting preferences against resuscitation in medical orders may be beneficial to many patients.

    LGBT (lesbian, gay, bisexual, transgender) patients suffer from stigma and discrimination when seeking healthcare. A large LGBT healthcare survey revealed that 56% of gay patients and 70% of transgender patients suffered some type of discrimination while seeking healthcare in 2014. The fostering of LGBT-friendly healthcare services is not just an advanced step of gender mainstreaming but also a fulfillment of health equality and equity. Additionally, LGBT-friendly healthcare services are expected to provide new opportunities for healthcare workers. Therefore, proactive government policies, education, research, and clinical practice should all encourage the development of these healthcare services. We look forward to a well-developed LGBT-friendly healthcare system in Taiwan. PMID:25631181

    Objective Studies show a high potential demand for psychiatric advance directives but low completion rates. The authors conducted a randomized study of a structured, manualized intervention to facilitate completion of psychiatric advance directives. Method A total of 469 patients with severe mental illness were randomly assigned to a facilitated psychiatric advance directive session or a control group that received written information about psychiatric advance directives and referral to resources in the public mental health system. Completion of an advance directive, its structure and content, and its short-term effects on working alliance and treatment satisfaction were recorded. Results Sixty-one percent of participants in the facilitated session completed an advance directive or authorized a proxy decision maker, compared with only 3% of control group participants. Psychiatrists rated the advance directives as highly consistent with standards of community practice. Most participants used the advance directive to refuse some medications and to express preferences for admission to specific hospitals and not others, although none used an advance directive to refuse all treatment. At 1-month follow-up, participants in the facilitated session had a greater working alliance with their clinicians and were more likely than those in the control group to report receiving the mental health services they believed they needed. Conclusions The facilitation session is an effective method of helping patients complete psychiatric advance directives and ensuring that the documents contain useful information about patients’ treatment preferences. Achieving the promise of psychiatric advance directives may require system-level policies to embed facilitation of these instruments in usual-care care settings. PMID:17074946

    The sharing of experiences in advanced practice nursing clinical courses allows for application of core principals to different facets of practice, with the potential to promote discussions beyond the course objectives, create opportunities for mentoring, foster critical thinking, and facilitate change and socialization into advanced practice. A pilot test of online, directed journaling, an innovative sharing and reflection strategy, was incorporated in a two-quarter community health advanced practice nursing clinical course in an attempt to enhance clinical learning. Six female graduate nursing students completed the journaling. A 10-item evaluation measure demonstrated that the online journaling strategy was highly effective and valuable for the students. An assessment of the journaling entries found multiple examples of discussion, mentoring, critical thinking, and socialization. Innovative online strategies should become the standard for sharing in advanced practice nursing education. PMID:15098912

    Untreated human epidermal growth factor receptor-2 (HER-2)-positive advanced breast cancer (ABC) is an aggressive disease, associated with a poor prognosis and short overall survival. HER-2-directed therapy prolongs both time to disease progression and overall survival when combined with chemotherapy and has become the standard of care for those with HER-2-positive breast cancer in the early and advanced settings. Despite the remarkable therapeutic impact HER-2-directed therapy has had on disease outcomes, some patients with HER-2-positive disease will have primary resistant disease and others will respond initially but will eventually have progression, underscoring the need for other novel therapeutic options. This article reviews recent phase III trial data and discusses a practical approach to sequencing of HER-2-directed therapy in patients with HER-2-positive ABC. The significant cumulative survival gains seen in these trials are slowly reshaping the landscape of HER-2-positive ABC outcomes. PMID:24212500

    2014-01-01

    This article enumerates and critically examines the potential grounds on which we might treat the case of a patient with an advance directive who attempted suicide, differently from one whose injuries were the result of an accident. Grounds for differentiation are distilled into two potential justifications. The first addresses the concern that withholding or withdrawing care from a patient with self-inflicted injuries would be aiding and abetting suicide.The second examines concerns about the patient's decisionmaking capacity. Ultimately, it is argued that while there might be legitimate reasons to hold the advance directive of a suicidal patient to a different standard of scrutiny, the fact that the patient's medical state was self-inflicted should not, in and of itself, necessarily invalidate the guidance of the directive. Finally, four practical recommendations are offered for negotiating similar cases. PMID:24779318

    The present article aimed to provide a comprehensive review of current status of end-of-life (EOL) care and sociocultural considerations in Korea, with focus on the EOL communication and use of advance directives (AD) in elderly Koreans. Through literature review, we discuss the current status of EOL care and sociocultural considerations in Korea, and provide a look-ahead. In Korea, patients often receive life-sustaining treatment until the very end of life. Advance care planning is rare, and most do-not-resuscitate decisions are made between the family and physician at the very end of patient's life. Koreans, influenced mainly by Confucian tradition, prefer a natural death and discontinuation of life-sustaining treatment. Although Koreans generally believe that death is natural and unavoidable, they tend not to think about or discuss death, and regard preparation for death as unnecessary. As a result, AD are completed by just 4.7% of the general adult population. This situation can be explained by several sociocultural characteristics including opting for natural death, wish not to burden others, preference for family involvement and trust in doctor, avoidance of talking about death, and filial piety. Patients often receive life-sustaining treatment until the very EOL, advance care planning and the use of AD is not common in Korea. This was related to unique sociocultural characteristics of Korea. A more active role of physicians, development of a more deliberate EOL discussion process, development of culturally appropriate AD and promotion of advance care planning might be required to provide good EOL care in Korea.

    2001-01-01

    Effective security has aligned itself into the everyday operations of a healthcare organization. This is evident in every regional market segment, regardless of size, location, and provider clinical expertise or organizational growth. This research addresses key security issues from an acute care provider to freestanding facilities, from rural hospitals and community hospitals to large urban teaching hospitals. Security issues and concerns are identified and addressed daily by senior and middle management. As provider campuses become larger and more diverse, the hospitals surveyed have identified critical changes and improvements that are proposed or pending. Mitigating liabilities and improving patient, visitor, and/or employee safety are consequential to the performance and viability of all healthcare providers. Healthcare organizations have identified the requirement to compete for patient volume and revenue. The facility that can deliver high-quality healthcare in a comfortable, safe, secure, and efficient atmosphere will have a significant competitive advantage over a facility where patient or visitor security and safety is deficient. Continuing changes in healthcare organizations' operating structure and healthcare geographic layout mean changes in leadership and direction. These changes have led to higher levels of corporate responsibility. As a result, each organization participating in this benchmark study has added value and will derive value for the overall benefit of the healthcare providers throughout the nation. This study provides a better understanding of how the fundamental security needs of security in healthcare organizations are being addressed and its solutions identified and implemented.

    Following the introduction of the Patient Self-Determination Act of 1990, the Veterans Health Administration developed its own advance medical directive (AMD) policy, which most recently states that documentation is mandatory for all hospital patients in all settings. The object of this study was to assess the effectiveness of AMD documentation at a local Veterans Affairs Medical Center. AMD documentation was compared among three inpatient services: surgery, medicine, and psychiatry. Retrospective in nature, 594 inpatient cases were compared. Results revealed that, overall, the rate of AMD documentation was 37.7%. AMD documentation on surgery was statistically more frequent (45.6%) than for either medicine (33.2%) or psychiatry (34.5%). The difference between the numbers of days to AMD documentation for all three services was not statistically significant. While there was no statistically significant difference across gender, Caucasians had AMDs documented more frequently than African Americans (p < .001). Logistic regression reveals that social worker and physician intervention, not patient-specific variables, are the primary predictors of AMD incidence. Policy makers may need to consider the realities of hospital care, especially in emergency settings, and be more specific in the steps of implementation of the policy in the evenings, weekends, and holidays. True adherence to policy implementation may require hospital administrators to increase staff and educational efforts so that the concept of AMD communication and documentation is completely explained to all staff and patients. Policy should include an electronic record reminder that is renewed every 3 years and provisions for accommodating patients who arrive on weekends and holidays, with special awareness of the particular communication needs of minority groups. The study conclusions are that further inquiry is needed to understand these policy nuances to enable the Veterans Affairs Administration to

    The reflection upon the humanisation of the end-of-life process within healthcare systems and the implication of healthcare professionals is the main objective of this article. The evolution of the model of care and nurses leadership role at the end-of-life process is evaluated. This analysis starts from the first European references regarding advance wills, made in 1997 at the Oviedo Convention, until the introduction of the idea of advance directives incorporated into Spanish law in 2002. It sets the concept of advance planning in health-related decisions, which establishes a process of voluntary dialogue where every person can clarify values, preferences and wishes regarding the final moments of life, with the support of the healthcare professionals.

    2010-03-01

    Advance directives are often used to help patients articulate their end-of-life treatment preferences and guide proxy decision makers in making health care decisions when patients cannot. This case study and commentary puts forth a situation in which a palliative care consultation team encountered a patient with an advance directive that instructed her proxy decision maker to consider estate tax implications when making end-of-life decisions. Following presentation of the case, the authors focus on two ethical issues: 1) the appropriateness of considering patients' financial goals and values in medical decision making and 2) whether certain kinds of patient values should be considered more or less relevant than others as reasons for expressed treatment preferences. Clinicians are encouraged to accept a wide range of patient values as relevant to the clinical decision-making process and to balance the influence of those values with more traditional notions of clinical harm and benefit.

    In addressing the ethical and legal problems of advanced directives, the article discusses whether respect for the autonomy of the so-called "incompetent" patients is possible and morally required. Starting with a critique of how modern medicine threatens patient autonomy and care (2.), the author goes on to highlight the mutual interdependence between respect for autonomy and patient care as two moral requirements arising from respect for human dignity (3.). Finally; the article elucidates the practical consequences as they relate to a treatment approach for each patient that is simultaneously caring and respectful of their autonomy, commenting on the ramifications for a sensitive and conscientious approach to advanced medical directives and for the special -role of nursing in this context.

    Biobank donors and biobank governance face a conceptual challenge akin to clinical patients and their designated surrogate decision-makers: the necessity of making decisions and policies now that must be implemented under future unknown circumstances. We propose that biobanks take advantage of this parallel to learn lessons from the historical trajectory of advance directives and develop models analogous to current “best practice” advance directives such as values histories and the Five Wishes. We suggest how such models could improve biobanks’ engagement both with communities and with individual donors by being more honest about the limits of current disclosure and eliciting information to ensure protection of donor interests more robustly through time than current “informed consent” processes in biobanking.

    The role of gravity-induced phenomena in bulk CdTe crystal growth is studied with emphasis placed on the negative effects of buoyancy-driven convection, container effects, and hydrostatic pressure. An earth-bound crystal growth data base utilizing NASA's prototype advanced automated directional solidification furnace is described. Growth procedures that can be employed in a microgravity environment aboard the Space Shuttle or Space Station are presented. It is found that NASA's directional solidification furnace can produce Bridgman-type CdTe and has the potential for producing it in space.

    Background Among intermediate to high-risk patients with chest pain, we have shown that a cardiac magnetic resonance (CMR) stress-test strategy implemented in an observation unit (OU) reduces 1-year healthcare costs compared to inpatient care. In this study, we compare two OU strategies to determine among lower-risk patients if a mandatory CMR stress test strategy was more effective than a physicians’ ability to select a stress test modality. Methods and Results Upon ED arrival and referral to the OU for management of low to intermediate-risk chest pain, 120 individuals were randomized to receive an a) CMR stress imaging test (n=60), or b) a provider selected stress test (n=60: stress echo [62%], CMR (32%), cardiac catheterization (3%), nuclear (2%), and coronary CT [2%]). No differences were detected in length of stay (median CMR = 24.2 hours vs 23.8 hours, p=0.75), catheterization without revascularization (CMR=0% vs 3%), appropriateness of admission decisions (CMR 87% vs 93%, p=0.36), or 30-day ACS (both 3%). Median cost was higher among those randomized to the CMR mandated group ($2005 vs $1686, p<0.001). Conclusions In patients with lower-risk chest pain receiving ED-directed OU care, the ability of a physician to select a cardiac stress imaging modality (including echocardiography, CMR, or radionuclide testing) was more cost effective than a pathway that mandates a CMR stress test. Contrary to prior observations in individuals with intermediate to high-risk chest pain, in those with lower risk chest pain, these results highlight the importance of physician-related choices during ACS diagnostic protocols.

    Modern scientific inquiries require significant data-driven evidence and trans-disciplinary expertise to extract valuable information and gain actionable knowledge about natural processes. Effective evidence-based decisions require collection, processing and interpretation of vast amounts of complex data. The Moore's and Kryder's laws of exponential increase of computational power and information storage, respectively, dictate the need rapid trans-disciplinary advances, technological innovation and effective mechanisms for managing and interrogating Big Healthcare Data. In this article, we review important aspects of Big Data analytics and discuss important questions like: What are the challenges and opportunities associated with this biomedical, social, and healthcare data avalanche? Are there innovative statistical computing strategies to represent, model, analyze and interpret Big heterogeneous data? We present the foundation of a new compressive big data analytics (CBDA) framework for representation, modeling and inference of large, complex and heterogeneous datasets. Finally, we consider specific directions likely to impact the process of extracting information from Big healthcare data, translating that information to knowledge, and deriving appropriate actions.

    There are strong pragmatic and moral reasons for receiving societies to address access to healthcare for migrants. Receiving societies have a pragmatic interest in sustaining migrants' health to facilitate integration; they also have a moral obligation to ensure migrants' access to healthcare according to international human rights principles. The intention of this thesis is to increase the understanding of migrants' access to healthcare by exploring two study aims: 1) Are there differences in migrants' access to healthcare compared to that of non-migrants? (substudy I and II); and 2) Why are there possible differences in migrants' access to healthcare compared to that of non-migrants? (substudy III and IV). The thesis builds on different methodological approaches using both register-based retrospective cohort design, cross-sectional design and survey methods. Two different measures of access were used to explore differences: 1) cancer stage at diagnosis as a clinical outcome and 2) emergency room (ER) contacts as a utilisation measure. Both informal and formal barriers to access were studied to explore why possible differences existed including: 1) motivation for using ER; and 2) asylum seekers' healthcare entitlements. Different definitions of migration and ethnicity were investigated including: country of birth and residence status. Substudy I showed a tendency towards more advanced stage at diagnosis or unknown stage among most subgroups of migrant women with a history of cancer compared to non-migrant women. Sub-study II found that some migrants (those born in Somalia, Turkey and Ex-Yugoslavia) use ER services more frequently than do non-migrants whereas others have the same or lower utilisation levels. As a consequence, substudy III was undertaken, which documented that more migrant within all subgroups had considered contacting a primary caregiver before visiting the ER compared to non-migrants, but that migrants experienced communication problems herein

  8. A prescription for Lean healthcare.

    PubMed

    Wood, David

    2014-01-01

    The adoption of Lean in the healthcare industry has been an important advancement, and not just for healthcare management. Evidence suggests that Lean can improve labour and capital efficiencies, reduce the throughput time for patients and enhance the quality of care. However, the adoption of Lean has generated large variations in results and even wider-ranging suggestions on how to implement Lean in a healthcare setting. In this article, the author examines three very similar hospitals that implemented Lean in the emergency department during the same time. Through an examination of longitudinal data and a collection of unstructured interviews, the author found that implementation does make a substantial difference to long-term results. Although the presence of strong and persistent leadership can have favourable results on performance in the short term, these performance improvements are not sustainable. To have a long-term impact, healthcare providers need to engage all of the stakeholders in the healthcare system and create a culture that is continuously focused on the improvement of the patient healthcare experience.

    This review examines the vast catalytic and therapeutic potential offered by type I (i.e. oxygen-insensitive) nitroreductase enzymes in partnership with nitroaromatic prodrugs, with particular focus on gene-directed enzyme prodrug therapy (GDEPT; a form of cancer gene therapy). Important first indications of this potential were demonstrated over 20 years ago, for the enzyme-prodrug pairing of Escherichia coli NfsB and CB1954 [5-(aziridin-1-yl)-2,4-dinitrobenzamide]. However, it has become apparent that both the enzyme and the prodrug in this prototypical pairing have limitations that have impeded their clinical progression. Recently, substantial advances have been made in the biodiscovery and engineering of superior nitroreductase variants, in particular development of elegant high-throughput screening capabilities to enable optimization of desirable activities via directed evolution. These advances in enzymology have been paralleled by advances in medicinal chemistry, leading to the development of second- and third-generation nitroaromatic prodrugs that offer substantial advantages over CB1954 for nitroreductase GDEPT, including greater dose-potency and enhanced ability of the activated metabolite(s) to exhibit a local bystander effect. In addition to forging substantial progress towards future clinical trials, this research is supporting other fields, most notably the development and improvement of targeted cellular ablation capabilities in small animal models, such as zebrafish, to enable cell-specific physiology or regeneration studies.

    This joint article reflects the authors' personal views regarding noteworthy advances in the neuroscience of consciousness in the last 10 years, and suggests what we feel may be promising future directions. It is based on a small conference at the Samoset Resort in Rockport, Maine, USA, in July of 2012, organized by the Mind Science Foundation of San Antonio, Texas. Here, we summarize recent advances in our understanding of subjectivity in humans and other animals, including empirical, applied, technical, and conceptual insights. These include the evidence for the importance of fronto-parietal connectivity and of “top-down” processes, both of which enable information to travel across distant cortical areas effectively, as well as numerous dissociations between consciousness and cognitive functions, such as attention, in humans. In addition, we describe the development of mental imagery paradigms, which made it possible to identify covert awareness in non-responsive subjects. Non-human animal consciousness research has also witnessed substantial advances on the specific role of cortical areas and higher order thalamus for consciousness, thanks to important technological enhancements. In addition, much progress has been made in the understanding of non-vertebrate cognition relevant to possible conscious states. Finally, major advances have been made in theories of consciousness, and also in their comparison with the available evidence. Along with reviewing these findings, each author suggests future avenues for research in their field of investigation. PMID:24198791

    Objective To evaluate the impact of advanced pharmacy practice experiences (APPEs) on doctor of pharmacy (PharmD) students' readiness for self-directed learning. Methods The Self-Directed Learning Readiness Scale (SDLRS) was administered to students prior to and after completing their APPEs. SDLRS is a validated instrument that determines the relative degree to which students have the attitudes and motivation to engage in self-directed learning. Results Seventy-seven (64%) students completed the SDLRS prior to starting their APPEs and 80 (67%) students completed the instrument after completing their APPEs. Forty-six (38%) students completed both. Prior to starting their APPEs, 74% of students scored greater than 150 on the SDLRS, indicating a high level of readiness for self-directed learning. No significant difference was found between the mean scores of students who took the SDLRS both prior to (159 ± 20) and after completing their APPEs (159 ± 24; p > 0.05). Conclusion Students at our institution appear to be ready for self-directed learning but APPEs had a minimal impact on their readiness for self-directed learning. PMID:19657498

    Direct osmotic concentration (DOC) has been identified as a high potential technology for recycling of wastewater to drinking water in advanced life support (ALS) systems. As a result the DOC process has been selected for a NASA Rapid Technology Development Team (RTDT) effort. The existing prototype system has been developed to a Technology Readiness Level (TRL) 3. The current project focuses on advancing the development of this technology from TRL 3 to TRL 6 (appropriate for human rated testing). A new prototype of a DOC system is been designed and fabricated that addresses the deficiencies encountered during the testing of the original system and allowing the new prototype to achieve TRL 6. Background information is provided about the technologies investigated and their capabilities, results from preliminary tests, and the milestones plan and activities for the RTDT program intended to develop a second generation prototype of the DOC system.

    Changes in life expectancy, healthy life expectancy and health seeking behaviour are having an impact on the demand for care. Such changes could occur across the whole population, or for specific groups. Changes for specific groups will be particularly affected by policy initiatives, while both these and wider changes will be affected by people's levels of engagement with their health and the health service itself. Levels of education, income and media coverage of health issues are also important. These factors could also encourage an increase in people caring for themselves and their families or community. People are now expecting a patient-centred service with safe high quality treatment, comfortable accommodation services, fast access and an integrated joined-up system. The uptake of integrated Information and Communication technologies (ICT) will be crucial. Healthcare Compunetics, the combination of computing and networking customised for medical and care, will provide the common policy and framework for combined multi-disciplinary research, development, implementation and usage.

    The purpose of the experiments for the Advanced Automated Directional Solidification Furnace (AADSF) is to determine how gravity-driven convection affects the composition and properties of alloys (mixtures of two or more materials, usually metal). During the USMP-4 mission, the AADSF will solidify crystals of lead tin telluride and mercury cadmium telluride, alloys of compound semiconductor materials used to make infrared detectors and lasers, as experiment samples. Although these materials are used for the same type application their properties and compositional uniformity are affected differently during the solidification process.

    The ability to plan for the future beyond immediate needs would be adaptive to many animal species, but is widely thought to be uniquely human. Although studies in captivity have shown that great apes are capable of planning for future needs, it is unknown whether and how they use this ability in the wild. Flanged male Sumatran orangutans (Pongo abelii) emit long calls, which females use to maintain earshot associations with them. We tested whether long calls serve to communicate a male's ever-changing predominant travel direction to facilitate maintaining these associations. We found that the direction in which a flanged male emits his long calls predicts his subsequent travel direction for many hours, and that a new call indicates a change in his main travel direction. Long calls given at or near the night nest indicate travel direction better than random until late afternoon on the next day. These results show that male orangutans make their travel plans well in advance and announce them to conspecifics. We suggest that such a planning ability is likely to be adaptive for great apes, as well as in other taxa. PMID:24040357

    Background Chronic obstructive pulmonary disease (COPD) is a health problem that is becoming increasingly attended-to in Primary Care (PC). However, there is a scarcity of health-care programs and studies exploring the implementation of Clinical Practice Guidelines (CPG). The principal objective of the present study is to evaluate the effectiveness of a combined strategy directed towards health-care professionals and patients to improve the grade of clinical control and the quality-of-life (QoL) of the patients via a feedback on their state-of-health. A training plan for the health-care professionals is based on CPG and health education. Method/Design Multi-centred, before-after, quasi experimental, prospective study involving an intervention group and a control group of individuals followed-up for 12 months. The patients receive attention from urban and semi-urban Primary Care Centres (PCC) within the administrative area of the Costa de Ponent (near Barcelona). All the pacients corresponding to the PCC of one sub-area were assigned to the intervention group and patients from the rest of sub-areas to the group control. The intervention includes providing data to the health-care professionals (clinician/nurse) derived from a clinical history and an interview. A course of training focused on aspects of CPG, motivational interview and health education (tobacco, inhalers, diet, physical exercise, physiotherapy). The sample random includes a total of 801 patients (≥ 40 years of age), recorded as having COPD, receiving attention in the PCC or at home, who have had at least one clinical visit, and who provided written informed consent to participation in the study. Data collected include socio-demographic characteristics, drug treatment, exacerbations and hospital admissions, evaluation of inhaler use, tobacco consumption and life-style and health-care resources consumed.

    Psychiatric advance directives (ADs) allow an individual to state their preferences for future treatment at times when they may be unable to make considered decisions. There are differences in their form and legal value and the process associated with their use and completion. Several studies have now been completed to assess the impact of ADs on service use and coercion. Their results give a mixed picture but directives nevertheless have the potential to support the empowerment process, minimize experienced coercion, and improve coping strategies. These may in turn reduce the frequency of in-patient service use. Further studies on the different processes of facilitation involved and on different populations are necessary to improve our knowledge and use of these potentially powerful interventions.

    Large format (i.e., >25 cm) cranioplasty is a challenging procedure not only from a cosmesis standpoint, but also in terms of ensuring that the patient's brain will be well-protected from direct trauma. Until recently, when a patient's own cranial flap was unavailable, these goals were unattainable. Recent advances in implant computer-aided design and 3-dimensional (3-D) printing are leveraging other advances in regenerative medicine. It is now possible to 3-D-print patient-specific implants from a variety of polymer, ceramic, or metal components. A skull template may be used to design the external shape of an implant that will become well integrated in the skull, while also providing beneficial distribution of mechanical force in the event of trauma. Furthermore, an internal pore geometry can be utilized to facilitate the seeding of banked allograft cells. Implants may be cultured in a bioreactor along with recombinant growth factors to produce implants coated with bone progenitor cells and extracellular matrix that appear to the body as a graft, albeit a tissue-engineered graft. The growth factors would be left behind in the bioreactor and the graft would resorb as new host bone invades the space and is remodeled into strong bone. As we describe in this review, such advancements will lead to optimal replacement of cranial defects that are both patient-specific and regenerative. PMID:26171578

    Objectives To review the responses of advance directives signed by Jehovah’s Witness patients prior to undergoing surgery at a gynecologic oncology service. Study design A retrospective chart review of gynecologic oncology patients undergoing surgery at a bloodless surgery center from 1998–2007 was conducted. Demographic, pathologic, and clinical data were recorded. The proportion of patients who accepted and refused various blood-derived products was determined and was compared to previously published results from a similar study of labor and delivery unit patients. Results No gynecologic oncology patients agreed to accept transfusions of whole blood, red cells, white cells, platelets, or plasma under any circumstance, whereas 9.8% of pregnant patients accepted transfusion (P=0.0385). However, 98% of gynecologic oncology patients agreed to accept some blood products, including fractions such as albumin, immunoglobulins, and clotting factors, while only 39% of pregnant patients agreed (P<0.0001). In addition, all gynecologic oncology patients (100%) accepted intraoperative hemodilution, compared to 55% of pregnant patients (P<0.0001). Conclusion Our results confirm the commonly held belief that the majority of Jehovah’s Witness patients refuse to accept major blood components. However, Jehovah’s Witness patients at a gynecologic oncology service will accept a variety of blood-derived products (minor fractions) and interventions designed to optimize outcomes when undergoing transfusion-free surgery. Patients presenting to a gynecologic oncology service respond differently to advanced directives related to bloodless surgery, as compared to patients from an obstetrical service. PMID:25565911

    Health-care service provider networks are regarded as an important instrument to overcome the widely criticised fragmentation and sectoral partition of the German health-care system. The first part of this paper incorporates health-care service provider networks in the field of health-care research. The system theoretical model and basic functions of health-care research are used for this purpose. Furthermore already established areas of health-care research with strong relations to health-care service provider networks are listed. The second part of this paper introduces some innovative options for reimbursing health-care service provider networks which can be regarded as some results of network-oriented health-care research. The origins are virtual budgets currently used in part to reimburse integrated care according to §§ 140a ff. SGB V. Describing and evaluating this model leads to real budgets (capitation) - a reimbursement scheme repeatedly demanded by SVR-Gesundheit (German governmental health-care advisory board), for example, however barely implemented. As a final step a direct reimbursement of networks by the German sickness fund is discussed. Advantages and challenges are shown. The development of the different reimbursement schemes is partially based on models from the USA. PMID:25625796

    We have studied national laws on advance directives in various Western European countries: Romance-speaking countries (Italy, France, Portugal, and Spain), English-speaking countries (Ireland and the United Kingdom), and German-speaking countries (Austria, Germany, and Switzerland). We distinguish two potentially complementary types of advance medical declaration: the 'living will' and the nomination of a legal proxy. After examining the similarities and differences between countries, we analyse in detail the legislation of four countries (Spain, France, England, and Germany), since the other countries in this survey have similar legal principles and/or a similar political approach. In conclusion, we note that in all the countries examined, advance directives have been seen as an instrument to enable the patient's right to self-determination. Notwithstanding, in Romance-speaking countries, the involvement of physicians in the end-of-life process and risks arising from the execution of advance directives were also considered.

    Older adults living in healthcare communities (HCCs) have multiple comorbidities and are at increased risk of malnutrition and unintended weight loss. Aging affects nearly every system as well as body composition and structure, causing physiological changes that can affect nutrition status. A significant percentage (56%) of residents who live in nursing facilities require extensive help to eat and have dental problems such as ill-fitting dentures, missing teeth, and swallowing problems, which can lead to inadequate caloric intake and unintended weight loss. Alzheimer disease or dementia is prevalent in both nursing facilities and in assisted living/residential care communities, where it affects 45% of older adults. In cognitively impaired residents, most tube feeding placements occur in the acute care setting and result in significant use of additional healthcare resources, along with high postinsertion mortality rates within 60 days of insertion. Nursing facilities receiving Medicare or Medicaid funding must abide by state and federal regulations and undergo rigorous surveys while balancing complex decisions related to initial placement of feeding tubes. Healthcare professionals must recognize the importance of establishing nutrition treatment goals that are resident centered and that respect the unique values and personal decisions of the older adult. Informed choice, resident-centered care decisions, and the review of living wills and/or advance directives are essential in the decision-making process. After enteral nutrition is started, healthcare practitioners must carefully review the physician's orders and administer and monitor the resident's tolerance, checking for potential complications.

  6. The role of advance euthanasia directives as an aid to communication and shared decision-making in dementia.

    Recent evaluation of the practice of euthanasia and related medical decisions at the end of life in the Netherlands has shown a slight decrease in the frequency of physician-assisted death since the enactment of the Euthanasia Law in 2002. This paper focuses on the absence of euthanasia cases concerning patients with dementia and a written advance euthanasia directive, despite the fact that the only real innovation of the Euthanasia Law consisted precisely in allowing physicians to act upon such directives. The author discusses two principal reasons for this absence. One relates to the uncertainty about whether patients with advanced dementia truly experience the suffering they formerly feared. There is reason to assume that they don't, as a consequence of psychological adaptation and progressive unawareness (anosognosia). The second, more fundamental reason touches upon the ethical relevance of shared understanding and reciprocity. The author argues that, next to autonomy and mercifulness, "reciprocity" is a condition sine qua non for euthanasia. The absence thereof in advanced dementia renders euthanasia morally inconceivable, even if there are signs of suffering and notwithstanding the presence of an advance euthanasia directive. This does not mean, however, that advance euthanasia directives of patients with dementia are worthless. They might very well have a role in the earlier stages of certain subtypes of the disease. To illustrate this point the author presents a case in which the advance directive helped to create a window of opportunity for reciprocity and shared decision-making. PMID:19181882

    The 1990 Advanced Research and Technology Development (AR TD) Direct Utilization, and Instrumentation and Diagnostics Contractors Review Meeting was held September 16--18, 1990, at the Hyatt at Chatham Center in Pittsburgh, PA. The meeting was sponsored by the US Department of Energy (DOE), Office of Fossil Energy, and the Pittsburgh and Morgantown Energy Technology Centers. Each year the meeting provides a forum for the exchange of information among the DOE AR TD contractors and interested parties. This year's meeting was hosted by the Pittsburgh Energy Technology Center and was attended by 120 individuals from industry, academia, national laboratories, and other governmental agencies. Papers were presented on research addressing coal surface, science, devolatilization and combustion, ash behavior, emission controls for gases particulates, fluid bed combustion and utilization in diesels and turbines. Individual reports are processed separately for the data bases.

    An advanced leading-edge concept was analyzed using the space shuttle leading edge system as a reference model. The comparison indicates that a direct-bond system utilizing a high temperature (2700 F) fibrous refractory composite insulation tile bonded to a high temperature (PI/graphite) composite structure can result in a weight savings of up to 800 lb. The concern that tile damage or loss during ascent would result in adverse entry aerodynamics if a leading edge tile system were used is addressed. It was found from experiment that missing tiles (as many as 22) on the leading edge would not significantly affect the basic force-and-moment aerodynamic coefficients. Additionally, this concept affords a degree of redundancy to a thermal protection system in that the base structure (being a composite material) ablates and neither melts nor burns through when subjected to entry heating in the event tiles are actually lost or damaged during ascent.

    Lamotrigine is recently recognized as a persistent pharmaceutical in the water environment and wastewater effluents. Its degradation was studied under UV and ozone advanced oxidation treatments with reaction kinetics of lamotrigine with ozone (≈4 M(-1)s(-1)), hydroxyl radical [(2.1 ± 0.3) × 10(9)M(-1)s(-1)] and by UV photolysis with low and medium pressure mercury vapor lamps [quantum yields ≈0 and (2.7 ± 0.4)× 10(-4) respectively] determined. All constants were measured at pH 6 and at temperature ≈20°C. The results indicate that lamotrigine is slow to respond to direct photolysis or oxidation by ozone and no attenuation of the contaminant is expected in UV or ozone disinfection applications. The compound reacts rapidly with hydroxyl radicals indicating that advanced oxidation processes would be effective for its treatment. Degradation products were identified under each treatment process using accurate mass time-of-flight spectrometry and pathways of decay were proposed. The main transformation pathways in each process were: dechlorination of the benzene ring during direct photolysis; hydroxyl group addition to the benzene ring during the reaction with hydroxyl radicals; and triazine ring opening after reaction with ozone. Different products that form in each process may be to a varying degree less environmentally stable than the parent lamotrigine. In addition, a novel method of ozone quenching without addition of salts is presented. The new quenching method would allow subsequent mass spectrometry analysis without a solid phase extraction clean-up step. The method involves raising the pH of the sample to approximately 10 for a few seconds and lowering it back and is therefore limited to applications for which temporary pH change is not expected to affect the outcome of the analysis.

    1995-03-01

    The Advanced Concepts for Direct Coal Liquefaction program was initiated by the Department of Energy in 1991 to develop technologies that could significantly reduce the cost of producing liquid fuels by the direct liquefaction of coal. The advanced 2-stage liquefaction technology that was developed at Wilsonville over the past 10 years has contributed significantly toward decreasing the cost of producing liquids from coal to about $33/bbl. It remains, however, the objective of DOE to further reduce this cost to a level more competitive with petroleum based products. This project, among others, was initiated to investigate various alternative approaches to develop technologies that might ultimately lead to a 25 % reduction in cost of product. In this project a number of novel concepts were investigated, either individually or in a coupled configuration that had the potential to contribute toward meeting the DOE goal. The concepts included mature technologies or ones closely related to them, such as coal cleaning by oil agglomeration, fluid coking and distillate hydrotreating and dewaxing. Other approaches that were either embryonic or less developed were chemical pretreatment of coal to remove oxygen, and dispersed catalyst development for application in the 2-stage liquefaction process. This report presents the results of this project. It is arranged in four sections which were prepared by participating organizations responsible for that phase of the project. A summary of the overall project and the principal results are given in this section. First, however, an overview of the process economics and the process concepts that were developed during the course of this program is presented.

    Tuberculosis is the leading infectious cause of death worldwide, with 9·6 million cases and 1·5 million deaths reported in 2014. WHO estimates 480,000 cases of these were multidrug resistant (MDR). Less than half of patients who entered into treatment for MDR tuberculosis successfully completed that treatment, mainly due to high mortality and loss to follow-up. These in turn illustrate weaknesses in current treatment regimens and national tuberculosis programmes, coupled with operational treatment challenges. In this Review we provide an update on recent developments in the tuberculosis drug-development pipeline (including new and repurposed antimicrobials and host-directed drugs) as they are applied to new regimens to shorten and improve outcomes of tuberculosis treatment. Several new or repurposed antimicrobial drugs are in advanced trial stages for MDR tuberculosis, and two new antimicrobial drug candidates are in early-stage trials. Several trials to reduce the duration of therapy in MDR and drug-susceptible tuberculosis are ongoing. A wide range of candidate host-directed therapies are being developed to accelerate eradication of infection, prevent new drug resistance, and prevent permanent lung injury. As these drugs have been approved for other clinical indications, they are now ready for repurposing for tuberculosis in phase 2 clinical trials. We assess risks associated with evaluation of new treatment regimens, and highlight opportunities to advance tuberculosis research generally through regulatory innovation in MDR tuberculosis. Progress in tuberculosis-specific biomarkers (including culture conversion, PET and CT imaging, and gene expression profiles) can support this innovation. Several global initiatives now provide unique opportunities to tackle the tuberculosis epidemic through collaborative partnerships between high-income countries and middle-income and low-income countries for clinical trials training and research, allowing funders to

    As the market for telemedicine products and services expands, many long distance telecommunications carriers and regional Bell operating companies developed strategies for meeting healthcare's needs. Some initiated projects to display their capabilities or to receive returns on investments in telecommunications infrastructures. Their capabilities and use of advanced technologies vary. The level of their healthcare commitment and involvement also varies. Regional Bell companies compete fiercely with each other and with national carriers for consulting and implementation contracts, unrestricted by service area boundaries. On the following pages, representatives from most of the major telecommunications carriers express their firms' healthcare strategies and offer synopses of their notable healthcare projects. For many, their resources are vast, their expertise undisputed. Access to high-quality healthcare services stands to benefit from their involvement. PMID:10138394

    The use of integrated information systems for healthcare has been started more than a decade ago. In recent years, rapid advances in information integration methods have spurred tremendous growth in the use of integrated information systems in healthcare delivery. Various techniques have been used for probing such integrated systems. These techniques include service-oriented architecture (SOA), EAI, workflow management, grid computing, and others. Many applications require a combination of these techniques, which gives rise to the emergence of enterprise systems in healthcare. Development of the techniques originated from different disciplines has the potential to significantly improve the performance of enterprise systems in healthcare. This editorial paper briefly introduces the enterprise systems in the perspective of healthcare informatics. PMID:22760931

    In describing the inverted classroom model (ICM), the following paper is meant to provide an introduction to the subject matter and to serve as a practical guide for those wishing to employ its methods in basic and advanced medical training and education. The ICM is a blended-learning method in which a self-directed learning phase (individual phase) precedes the classroom-instruction phase. During the online phase, factual knowledge is imparted that serves as a basis for the classroom phase. The classroom phase should subsequently be used to assimilate and implement the previously gained knowledge. In contrast, traditional course concepts impart factual knowledge in lectures, for example, or in other face-to-face teaching formats and are followed by the students’ self-instruction in order to assimilate this knowledge. The goal of the ICM is the shift from passive learning to accelerated learning in order to foster learning at cognitively demanding levels such as analysis, synthesis and evaluation. The concurrent increase in production and use of screencasts and educational videos, the Open Educational Resources “movement” and the widespread use of Massive Open Online Courses (MOOCS) have contributed to the increased dissemination of the inverted-classroom method. The intention of the present paper is to provide an introduction to the subject matter and simultaneously to offer a short overview of important projects and research results in the field of medical education and other health professions. Furthermore, an outline is given of the advantages and disadvantages of the model as well as its potential benefit to the future of medical education and training. PMID:27275511

    A direct-execution parallel architecture for the Advanced Continuous Simulation Language (ACSL) is presented which overcomes the traditional disadvantages of simulations executed on a digital computer. The incorporation of parallel processing allows the mapping of simulations into a digital computer to be done in the same inherently parallel manner as they are currently mapped onto an analog computer. The direct-execution format maximizes the efficiency of the executed code since the need for a high level language compiler is eliminated. Resolution is greatly increased over that which is available with an analog computer without the sacrifice in execution speed normally expected with digitial computer simulations. Although this report covers all aspects of the new architecture, key emphasis is placed on the processing element configuration and the microprogramming of the ACLS constructs. The execution times for all ACLS constructs are computed using a model of a processing element based on the AMD 29000 CPU and the AMD 29027 FPU. The increase in execution speed provided by parallel processing is exemplified by comparing the derived execution times of two ACSL programs with the execution times for the same programs executed on a similar sequential architecture.

  18. Advanced Insights into Functional Brain Connectivity by Combining Tensor Decomposition and Partial Directed Coherence

    Leistritz, Lutz; Witte, Herbert; Schiecke, Karin

    2015-01-01

    Quantification of functional connectivity in physiological networks is frequently performed by means of time-variant partial directed coherence (tvPDC), based on time-variant multivariate autoregressive models. The principle advantage of tvPDC lies in the combination of directionality, time variance and frequency selectivity simultaneously, offering a more differentiated view into complex brain networks. Yet the advantages specific to tvPDC also cause a large number of results, leading to serious problems in interpretability. To counter this issue, we propose the decomposition of multi-dimensional tvPDC results into a sum of rank-1 outer products. This leads to a data condensation which enables an advanced interpretation of results. Furthermore it is thereby possible to uncover inherent interaction patterns of induced neuronal subsystems by limiting the decomposition to several relevant channels, while retaining the global influence determined by the preceding multivariate AR estimation and tvPDC calculation of the entire scalp. Finally a comparison between several subjects is considerably easier, as individual tvPDC results are summarized within a comprehensive model equipped with subject-specific loading coefficients. A proof-of-principle of the approach is provided by means of simulated data; EEG data of an experiment concerning visual evoked potentials are used to demonstrate the applicability to real data.

    The present behavioral study re-addresses the question of habit learning in Parkinson's disease (PD). Patients were early onset, non-demented, dopa-responsive, candidates for surgical treatment, similar to those we found earlier as suffering greater dopamine depletion in the putamen than in the caudate nucleus. The task was the same conditional associative learning task as that used previously in monkeys and healthy humans to unveil the striatum involvement in habit learning. Sixteen patients and 20 age- and education-matched healthy control subjects learned sets of 3 visuo-motor associations between complex patterns and joystick displacements during two testing sessions separated by a few hours. We distinguished errors preceding vs. following the first correct response to compare patients' performance during the earliest phase of learning dominated by goal-directed actions with that observed later on, when responses start to become habitual. The disease significantly retarded both learning phases, especially in patients under 60 years of age. However, only the late phase deficit was disease severity-dependent and persisted on the second testing session. These findings provide the first corroboration in Parkinson patients of two ideas well-established in the animal literature. The first is the idea that associating visual stimuli to motor acts is a form of habit learning that engages the striatum. It is confirmed here by the global impairment in visuo-motor learning induced by PD. The second idea is that goal-directed behaviors are predominantly caudate-dependent whereas habitual responses are primarily putamen-dependent. At the advanced PD stages tested here, dopamine depletion is greater in the putamen than in the caudate nucleus. Accordingly, the late phase of learning corresponding to the emergence of habitual responses was more vulnerable to the disease than the early phase dominated by goal-directed actions. PMID:23386815

    This paper describes recent advances in the science and technology of direct methanol fuel cells (DMFCs) made at Los Alamos National Laboratory (LANL). The effort on DMFCs at LANL includes work devoted to portable power applications, funded by the Defense Advanced Research Project Agency (DARPA), and work devoted to potential transport applications, funded by the US DOE. We describe recent results with a new type of DMFC stack hardware that allows to lower the pitch per cell to 2 mm while allowing low air flow and air pressure drops. Such stack technology lends itself to both portable power and potential transport applications. Power densities of 300 W/l and 1 kW/l seem achievable under conditions applicable to portable power and transport applications, respectively. DMFC power system analysis based on the performance of this stack, under conditions applying to transport applications (joint effort with U.C. Davis), has shown that, in terms of overall system efficiency and system packaging requirements, a power source for a passenger vehicle based on a DMFC could compete favorably with a hydrogen-fueled fuel cell system, as well as with fuel cell systems based on fuel processing on board. As part of more fundamental studies performed, we describe optimization of anode catalyst layers in terms of PtRu catalyst nature, loading and catalyst layer composition and structure. We specifically show that, optimized content of recast ionic conductor added to the catalyst layer is a sensitive function of the nature of the catalyst. Other elements of membrane/electrode assembly (MEA) optimization efforts are also described, highlighting our ability to resolve, to a large degree, a well-documented problem of polymer electrolyte DMFCs, namely "methanol crossover". This was achieved by appropriate cell design, enabling fuel utilization as high as 90% in highly performing DMFCs.

    Psychiatric Advance Directives (PADs) are documents that allow users with severe and chronic mental illnesses to notify their treatment preferences for future crisis relapses and to appoint a surrogate decision-maker for a period of incompetence. Despite many supposed clinical and organisational benefits, their take-up rate has remained very low and their clinical evaluation has given contradictory results for organisational outcomes. Intermediary results are available, however, which rely on different theoretical views about how PADs are supposed to work. We carried out a realist systematic review that considered the PAD as a multistage intervention including the definition of the document, its completion and its access and honouring. We identified the theoretical frameworks underlying this kind of intervention and examined the available evidence that supported or contradicted the expectations at each stage of the intervention. Forty-seven references were retrieved, ranging from 1996 to 2009. Three frameworks underlie a PAD intervention: enhancement of the autonomy of the user, improvement of the therapeutic alliance and integration of care through partnership working. Although designed in the first place with a view to sustaining the user's autonomy, results indicate that the intervention is more efficient within a therapeutic alliance framework. Moreover, much is known about the completion process and the content of the document, but very little about its access and honouring. The mixture of expectations makes the purpose of PADs unclear, for example, crisis relapse prevention or management, advance planning of long-term or emergency care, or reduction in the resort to coercion. This may explain their low take-up rates. Hence, frameworks and purpose have to be clarified. The shape of the whole intervention at each stage relies on such clarification. More research is needed, particularly on the later stages of the intervention, as the evidence for how PADs should

    Background In Japan, discussion concerning advance directives (ADs) has been on the rise during the past decade. ADs are one method proposed to facilitate the process of communication among patients, families and health care providers regarding the plan of care of a patient who is no longer capable of communicating. In this paper, we report the results of the first in-depth survey on the general population concerning the preferences and use of ADs in Japan. Method A self-administered questionnaire was sent via mail to a stratified random sampling of 560 residents listed in the residential registry of one district of Tokyo, Japan (n = 165,567). Association between correlating factors and specific preferences toward ADs was assessed using contingency table bivariate analysis and multivariate regression model to estimate independent contribution. Results Of the 560 questionnaires sent out, a total of 425 participants took part in the survey yielding a response rate of 75.9 %. The results of the present study indicate that: 1) the most important components to be addressed are the specifics of medical treatment at the end of life stage and disclosure of diagnosis and prognosis; 2) the majority of participants found it suitable to express their directives by word to family and/or physician and not by written documentation; 3) there is no strong need for legal measures in setting up an AD; 4) it is permissible for family and physician to loosely interpret one's directives; 5) the most suitable proxy is considered to be a family member, relative, or spouse. Multivariate analysis found the following five factors as significantly associated with preferences: 1) awareness regarding living wills, 2) experience with the use of ADs, 3) preferences for end-of-life treatment, 4) preferences for information disclosure, and 5) intentions of creating a will. Conclusions Written ADs might be useful in the Japanese setting when the individual either wishes: 1) to not provide a lot of

    The concept of primary healthcare was formulated at the international conference held in Alma-Ata (USSR) on September 6 to 12, 1978. Over the past quarter-century, the term "primary healthcare" has been widely used as a basis for implementing healthcare policies in various nations, especially those considered as developing countries. However many programs initiated in the name of the primary healthcare concept have only partially complied with the spirit of the final declaration of Alma-Ata. Analysis of the healthcare in Mali shows that the system followed that evolution. Although considerable time and energy were regrettably wasted in implementing the village health agent strategy, this phase may have been a necessary step in the political development of the state at that time. Recent changes in the country's healthcare system in compliance with the original principles of primary healthcare show that the 1978 declaration is sound and remains pertinent as democracy makes further gains in the world.

    A linear algebraic solution is provided for the problem of retrieving the location and time of occurrence of lightning ground strikes from an Advanced Lightning Direction Finder (ALDF) network. The ALDF network measures field strength, magnetic bearing and arrival time of lightning radio emissions. Solutions for the plane (i.e., no Earth curvature) are provided that implement all of tile measurements mentioned above. Tests of the retrieval method are provided using computer-simulated data sets. We also introduce a quadratic planar solution that is useful when only three arrival time measurements are available. The algebra of the quadratic root results are examined in detail to clarify what portions of the analysis region lead to fundamental ambiguities in source location. Complex root results are shown to be associated with the presence of measurement errors when the lightning source lies near an outer sensor baseline of the ALDF network. In the absence of measurement errors, quadratic root degeneracy (no source location ambiguity) is shown to exist exactly on the outer sensor baselines for arbitrary non-collinear network geometries. The accuracy of the quadratic planar method is tested with computer generated data sets. The results are generally better than those obtained from the three station linear planar method when bearing errors are about 2 deg. We also note some of the advantages and disadvantages of these methods over the nonlinear method of chi(sup 2) minimization employed by the National Lightning Detection Network (NLDN) and discussed in Cummins et al.(1993, 1995, 1998).

    Advance directives (ADs) have been legislated in many countries to protect patient autonomy regarding medical decisions at the end of life. China is facing a serious cancer burden and cancer patients' quality at the end of life should be a concern. However, limited studies have been conducted locally to gather information about attitudes toward ADs. The purpose of this study was to investigate the attitudes of Chinese cancer patients and family caregivers toward ADs and to explore the predictors that are associated with attitudes. The study indicated that although there was low awareness of ADs, most cancer patients and family caregivers had positive attitudes toward ADs after related information was explained to them. Participants preferred to discuss ADs with medical staff when they were diagnosed with a life-threatening disease. Preferences for refusing life-sustaining treatment and choosing Hospice-Palliative Care (HPC) at the end of life would increase the likelihood of agreeing with ADs. This suggests that some effective interventions to help participants better understand end-of-life treatments are helpful in promoting ADs. Moreover, the development of HPC would contribute to Chinese cancer patients and family caregivers agreeing with ADs. PMID:27529264

    Dementia is a progressive disease in which patients lose their ability to decide and communicate. Advance directives (AD) allow patients to express their preferences on end of life care in the early stages of the disease. Primary care practitioners (PCP) are in the best position to promote AD. The aim of this study was to elicit PCPs views about the discussion of AD with early stage dementia patients. A qualitative approach was taken, focus groups and individual interviews to elderly patients' PCPs from the Hospital italiano de buenos aires were conducted. A purposive sampling was performed, conforming homogeneous groups according to age and seniority. The discussion was stimulated by a vignette. We performed thematic content analysis in an interdisciplinary team. Twelve PCPs = 30 year of age, 32 middle-aged and 8 over 45 years participated of the study. The youngest group favored the discussion of AD while those over 45 regarded the family as the decision maker, and thus, the discussion as useless. Besides, they expressed that our society is not mature enough to discuss AD. Difficulties in AD implementation, in predicting the evolution of a patient's disease, the span of time between the discussion and AD implementation, lack of legislation and specific institutional policies were other factors that conditioned the discussion. Younger PCPs expressed concern on the lack of communication skills and difficulties to broach this subject with patients. PCPs perspectives on AD vary, their age should be taken into account when designing strategies to their implementation. PMID:22892082

    There has been growing concerns about racial and ethnic disparities in completion rates of advance directives (ADs) among community-dwelling older populations. While differences in AD completion rates in non-Hispanic Whites and African Americans have been reported, not much is known about the awareness and completion of ADs in other groups of ethnic minorities. Using a sample of community-dwelling Korean American older adults (n = 675) as a target, factors associated with their awareness and completion of ADs were explored. Guided by Andersen's behavioral health model, predisposing (age, sex, marital status, and education), need (chronic conditions and functional disability), and enabling variables (health insurance and acculturation) were included in the separate logistic regression models of AD awareness and AD completion. In both models, acculturation was found to be a significant predictor; those who had a higher level of acculturation were more likely to be aware of ADs and to have completed ADs. This study contributes to the knowledge about the role of acculturation in explaining AD awareness and completion among Korean American older adults and provides practice implications for possible AD educational interventions for this older adult minority population.

    Background Despite a recent statutory ruling stating the binding nature of advance directives (ADs), only a minority of the population has signed one. Yet, a majority deem it of utmost importance to ensure their wishes are followed through in case they are no longer able to decide. The reasons for this discrepancy have not yet been investigated sufficiently. Patients and methods This article is based on a survey of patients using a well-established structured questionnaire. First, patients were asked about their attitudes with respect to six therapeutic options at the end of life: intravenous fluids, artificial feeding, antibiotics, analgesia, chemotherapy/dialysis, and artificial ventilation; and second, they were asked about the negative effects related to the idea of ADs surveying their apprehensions: coercion to fulfill an AD, dictatorial reading of what had been laid down, and abuse of ADs. Results A total of 1,260 interviewees completed the questionnaires. A significant percentage of interviewees were indecisive with respect to therapeutic options, ranging from 25% (analgesia) to 45% (artificial feeding). There was no connection to health status. Apprehensions about unwanted effects of ADs were widespread, at 51%, 35%, and 43% for coercion, dictatorial reading, and abuse, respectively. Conclusion A significant percentage of interviewees were unable to anticipate decisions about treatment options at the end of life. Apprehensions about negative adverse effects of ADs are widespread.

    Valvo, M.; García-Tamayo, E.; Lafont, U.; Kelder, E. M.

    A direct approach for the synthesis and coating of advanced nanocomposite negative electrodes via a single-step process at low temperature is presented. Metal-oxide/PVdF nanocomposites are obtained in one step by electrospray pyrolysis of precursor solutions containing dissolved metal salts together with polyvinylidene fluoride (PVdF) as binder. In this way, small oxide nanoparticles are generated and dispersed in situ in the binder creating nanocomposite structures, while being coated at once as thin electrode layers on stainless steel coin cell cans. The intimate contact between the nanoparticles and the binder favours enhanced adhesion of the materials in the overall electrode structure and adequate electrochemical performances are obtained without any conductive additive. Three nanocomposite oxide/PVdF materials (i.e. SnO 2, CoO and Fe 2O 3) are reported here as preliminary examples of negative electrodes. The results show that this approach is suitable, not only for the fabrication of nanocomposite electrodes for Li-ion batteries, but also for other novel applications.

    Patients with localized prostate cancer (PCa) have several therapeutic options with good prognosis. However, survival of patients with high-risk, advanced PCa is significantly less than patients with early-stage, organ-confined disease. Testosterone and other androgens have been directly linked to PCa progression since 1941. In this review, we chronicle the discoveries that led to modern therapeutic strategies for PCa. Specifically highlighted is the biology of androgen receptor (AR), the nuclear receptor transcription factor largely responsible for androgen-stimulated and castrate-recurrent (CR) PCa. Current PCa treatment paradigms can be classified into three distinct but interrelated categories: targeting AR at pre-receptor, receptor, or post-receptor signaling. The continuing challenge of disease relapse as CR and/or metastatic tumors, destined to occur within three years of the initial treatment, is also discussed. We conclude that the success of PCa therapies in the future depends on targeting molecular mechanisms underlying tumor recurrence that still may affect AR at pre-receptor, receptor, and post-receptor levels.

    Emerging changes in health-care delivery are having a significant impact on the structure of health-care professionals' education. Today it is recognized that medical knowledge doubles every 6-8 years, with new medical procedures emerging everyday. While the half-life of medical information is so short, the average physician practices 30 years and the average nurse 40 years. Continuing education thus represents an important challenge to face. Recent advances in educational technology are offering an increasing number of innovative learning tools. Among these, Virtual Reality represents a promising area with high potential of enhancing the training of health-care professionals. Virtual Reality Training can provide a rich, interactive, engaging educational context, thus supporting experiential learning-by-doing; it can, in fact, contribute to raise interest and motivation in trainees and to effectively support skills acquisition and transfer, since the learning process can be settled within an experiential framework. Current virtual training applications for health-care differ a lot as to both their technological/multimedia sophistication and to the types of skills trained, varying for example from telesurgical applications to interactive simulations of human body and brain, to virtual worlds for emergency training. Other interesting applications include the development of immersive 3D environments for training psychiatrists and psychologists in the treatment of mental disorders. This paper has the main aim of discussing the rationale and main benefits for the use of virtual reality in health-care education and training. Significant research and projects carried out in this field will also be presented, followed by discussion on key issues concerning current limitations and future development directions.

    The increasing availability of Big Data in healthcare encourages investigators to seek answers to big questions. However, nonparametric approaches to analyzing these data can suffer from the curse of dimensionality, and traditional parametric modeling does not necessarily scale. Targeted learning (TL) combines semiparametric methodology with advanced machine learning techniques to provide a sound foundation for extracting information from data. Predictive models, variable importance measures, and treatment benefits and risks can all be addressed within this framework. TL has been applied in a broad range of healthcare settings, including genomics, precision medicine, health policy, and drug safety. This article provides an introduction to the two main components of TL, targeted minimum loss-based estimation and super learning, and gives examples of applications in predictive modeling, variable importance ranking, and comparative effectiveness research.

    Times are changing. Taiwan is one of the richest countries in the Asia Pacific region. It enacted its single-payer national health insurance program in 1995: in all estimates, it has been very successful. It has a strong healthcare system and the universal health insurance ensures that all citizens have grown to expect a high level of care. Healthcare systems are designed to meet the healthcare needs of target populations. There are a wide variety of healthcare systems around the world. In some countries, healthcare system planning is distributed among market participants, whereas in others planning is made more centrally among governments, trade unions, charities, religions, or other co-ordinated bodies to deliver planned healthcare services targeted to the populations they serve. However, healthcare planning has often been evolutionary rather than revolutionary. In healthcare all work carried out must be at the highest quality, and a much higher proportion of resources must be invested in quality in healthcare. The aim of this report is to give an overview of the healthcare service provision in Taiwan. PMID:23199110

    The role of big data in addressing the needs of the present healthcare system in US and rest of the world has been echoed by government, private, and academic sectors. There has been a growing emphasis to explore the promise of big data analytics in tapping the potential of the massive healthcare data emanating from private and government health insurance providers. While the domain implications of such collaboration are well known, this type of data has been explored to a limited extent in the data mining community. The objective of this paper is two fold: first, we introduce the emerging domain of big"healthcare claims data to the KDD community, and second, we describe the success and challenges that we encountered in analyzing this data using state of art analytics for massive data. Specically, we translate the problem of analyzing healthcare data into some of the most well-known analysis problems in the data mining community, social network analysis, text mining, and temporal analysis and higher order feature construction, and describe how advances within each of these areas can be leveraged to understand the domain of healthcare. Each case study illustrates a unique intersection of data mining and healthcare with a common objective of improving the cost-care ratio by mining for opportunities to improve healthcare operations and reducing hat seems to fall under fraud, waste,and abuse.

  20. Advanced thermal control for french-german direct broadcasting satellites TDF1/TVSAT

    Giovagnoli, F.

    The joint French-German programme of direct broadcasting is comprised of two distinct phases, i.e. 1. the development of the preoperational spacecraft (D3, F3), with 3 active channels out of 5 installed; 2. the production of operational satellites (D5, F5) with 5 channels active, each of them redundant. Aerospatiale is in charge among others of the Thermal Control of the Spacecraft. This paper deals with: thermal concept, analyses and tests programme. The developed platforms should also permit an easy adaptation to various payloads characterized by higher electrical power levels. The high power levels involved imply advanced thermal control for both Main Body and Antenna Module. The thermal control concept must have the following capabilities: • to transfer the concentrated, high power dissipations involved toward outer space, • to maintain in shadow phase (no emission) the correct temperatures with low or zero heating power, • to ensure, in transfer orbit phase (maximum duration about 300 h), satisfactory temperatures with reduced electrical power (satellite 3-axis stabilized, solar generator partially deployed), • to allow extremely non-symmetrical functionings. To solve these various problems, so far never simultaneously encountered on existing satellites, the following devices are used: • various heat pipe networks (D3/F3; 88 heat pipes, total length approx. 118 m), • large quantity of Optical Solar Reflectors (silica mirror, area approx. 6.3 m 2), • lightweight superinsulations, • various types of heaters, • Thermal Control Electronic (TCE) to switch ON/OFF heaters and monitor thermistors.

    The advance directives (ADs) have been adopted in many countries to defend patients' autonomy. In Italy, in the past, this topic gave rise to a heated debate involving philosophers, theologians, and politicians. In 2009, the government presented a bill of law on ADs firmly criticized from a scientific, moral and juridical point of view because the bill's content is against the principles of Italian Constitution, Italian Code of Medical Ethics, Oviedo Convention, and official statements of many scientific societies. Although the bill has passed the Low Chamber it lies, even since, in the Senate, lacking in regard any agreement among the political parties. The purpose of this article is to highlight that, in our country, patients, relatives and doctors deserve a law not only related to the specific topic of ADs, but - as in other European countries (Germany, Spain, France, UK) - aimed to deal with the complex issue of end of life care as a whole. This law should take into account the sound evidence existing in regard to the four fundamental principles supporting the best scientific and ethical approaches to the end of life issues: shared decision making process between doctors and patients/relatives; rejection of dying process marked by the suffering; withholding/withdrawing futile treatments together with palliative sedation as two crucial contributions to suppress the patient suffering and pain; clear-cut difference between these clinical/ethical options and euthanasia. At the same time, this law should be able to provide physicians with a legal coverage to make all the clinical and ethical decisions more and more complex because of the continuous evolution of medical science on one hand, and the impressive development of biotechnology on the other hand.

    Introduction Although most seriously ill Americans wish to avoid burdensome and aggressive care at the end of life, such care is often provided unless patients or family members specifically request otherwise. Advance directives (ADs) were created to provide opportunities to set limits on aggressive care near life's end. This study tests the hypothesis that redesigning ADs such that comfort-oriented care is provided as the default, rather than requiring patients to actively choose it, will promote better patient-centred outcomes. Methods and analysis This multicentre trial randomises seriously ill adults to receive 1 of 3 different ADs: (1) a traditional AD that requires patients to actively choose their goals of care or preferences for specific interventions (eg, feeding tube insertion) or otherwise have their care guided by their surrogates and the prevailing societal default toward aggressive care; (2) an AD that defaults to life-extending care and receipt of life-sustaining interventions, enabling patients to opt out from such care; or (3) an AD that defaults to comfort care, enabling patients to opt into life-extending care. We seek to enrol 270 patients who return complete, legally valid ADs so as to generate sufficient power to detect differences in the primary outcome of hospital-free days (days alive and not in an acute care facility). Secondary outcomes include hospital and intensive care unit admissions, costs of care, hospice usage, decision conflict and satisfaction, quality of life, concordance of preferences with care received and bereavement outcomes for surrogates of patients who die. Ethics and dissemination This study has been approved by the Institutional Review Boards at all trial centres, and is guided by a data safety and monitoring board and an ethics advisory board. Study results will be disseminated using methods that describe the results in ways that key stakeholders can best understand and implement. Trial registration number NCT02017548

    Ten years ago, the Institute of Medicine reported alarming data on the scope and impact of medical errors in the US and called for national efforts to address this problem. While efforts to improve patient safety have proliferated during the past decade, progress toward improvement has been frustratingly slow. Some of this lack of progress may be attributable to the persistence of a medical ethos, institutionalized in the hierarchical structure of academic medicine and healthcare organizations, that discourages teamwork and transparency and undermines the establishment of clear systems of accountability for safe care. The Lucian Leape Institute, established by the US National Patient Safety Foundation to provide vision and strategic direction for the patient safety work, has identified five concepts as fundamental to the endeavor of achieving meaningful improvement in healthcare system safety. These five concepts are transparency, care integration, patient/consumer engagement, restoration of joy and meaning in work, and medical education reform. This paper introduces the five concepts and illustrates the meaning and implications of each as a component of a vision for healthcare safety improvement. In future roundtable sessions, the Institute will further elaborate on the meaning of each concept, identify the challenges to implementation, and issue recommendations for policy makers, organizations, and healthcare professionals.

    Because of the trend toward consolidation in the healthcare field, many organizations have massive amounts of data stored in various information systems organizationwide, but access to the data by end users may be difficult. Healthcare organizations are being pressured to provide managers easy access to the data needed for critical decision making. One solution many organizations are turning to is implementing decision-support data warehouses. A data warehouse instantly delivers information directly to end users, freeing healthcare information systems staff for strategic operations. If designed appropriately, data warehouses can be a cost-effective tool for business analysis and decision support. PMID:10176450

    In many OECD countries, healthcare sectors have become increasingly concentrated as a result of mergers. However, detailed empirical insight into why healthcare providers merge is lacking. Also, we know little about the influence of national healthcare policies on mergers. We fill this gap in the literature by conducting a survey study on mergers among 848 Dutch healthcare executives, of which 35% responded (resulting in a study sample of 239 executives). A total of 65% of the respondents was involved in at least one merger between 2005 and 2012. During this period, Dutch healthcare providers faced a number of policy changes, including increasing competition, more pressure from purchasers, growing financial risks, de-institutionalisation of long-term care and decentralisation of healthcare services to municipalities. Our empirical study shows that healthcare providers predominantly merge to improve the provision of healthcare services and to strengthen their market position. Also efficiency and financial reasons are important drivers of merger activity in healthcare. We find that motives for merger are related to changes in health policies, in particular to the increasing pressure from competitors, insurers and municipalities. PMID:26055501

    Advancements in the development of a direction and position sensing fast neutron detector which utilizes the directional acoustic tensioned metastable fluid detector (D-ATMFD) are described. The resulting D-ATMFD sensor is capable of determining the direction of neutron radiation with a single compact detector versus use of arrays of detectors in conventional directional systems. Directional neutron detection and source positioning offer enhanced detection speeds in comparison to traditional proximity searching; including enabling determination of the neutron source shape, size, and strength in near real time. This paper discusses advancements that provide the accuracy and precision of ascertaining directionality and source localization information utilizing enhanced signal processing-cum-signal analysis, refined computational algorithms, and on-demand enlargement capability of the detector sensitive volume. These advancements were accomplished utilizing experimentation and theoretical modeling. Benchmarking and qualifications studies were successfully conducted with random and fission based special nuclear material (SNM) neutron sources (239Pu-Be and 252Cf). These results of assessments have indicated that the D-ATMFD compares well in technical performance with banks of competing directional fast neutron detector technologies under development worldwide, but it does so with a single detector unit, an unlimited field of view, and at a significant reduction in both cost and size while remaining completely blind to common background (e.g., beta-gamma) radiation. Rapid and direct SNM neutron source imaging with two D-ATMFD sensors was experimentally demonstrated, and furthermore, validated via multidimensional nuclear particle transport simulations utilizing MCNP-PoliMi. Characterization of a scaled D-ATMFD based radiation portal monitor (RPM) as a cost-effective and efficient 3He sensor replacement was performed utilizing MCNP-PoliMi simulations, the results of which

    The number of older adults with cognitive impairment is increasing, and such adults often require a surrogate to make decisions about health care. However, little is known about the aggressiveness of end-of-life care for these people, especially those who reside in the community. We found that cognitive impairment is common among older adults approaching the end of life, whether they live in the community or in a nursing home, and that nearly 30 percent of patients with severe dementia remained in the community until death. Among those patients, having an advance directive in the form of a living will was associated with significantly less aggressive care at the end of life, compared to similar patients without an advance directive-as measured by Medicare spending ($11,461 less per patient), likelihood of in-hospital death (17.9 percentage points lower), and use of the intensive care unit (9.4 percentage points lower). In contrast, advance directives were not associated with differences in care for people with normal cognition or mild dementia, whether they resided in the community or in a nursing home. Timely advance care planning after a diagnosis of cognitive impairment may be particularly important for older adults who reside in the community. PMID:24711329

    Introduction We conducted an epidemiologic evaluation of advance directives and do-not-resuscitate (DNR) prevalence among residents of extended care facilities (ECF) presenting to the emergency department (ED). Methods We performed a retrospective medical record review on ED patients originating from an ECF. Data were collected on age, sex, race, triage acuity, ED disposition, DNR status, power-of attorney (POA) status, and living will (LW) status. We generated descriptive statistics, and used logistic regression to evaluate predictors of DNR status. Results A total of 754 patients over 20 months met inclusion criteria; 533 (70.7%) were white, 351 (46.6%) were male, and the median age was 66 years (IQR 54–78). DNR orders were found in 124 (16.4%, 95% CI [13.9–19.1%]) patients. In univariate analysis, there was a significant difference in DNR by gender (10.5% female vs. 6.0% male with DNR, p=0.013), race (13.4% white vs. 3.1% non-white with DNR, p=0.005), and age (4.0% <65 years; 2.9% 65–74 years, p=0.101; 3.3% 75–84 years, p=0.001; 6.2% >84 years, p<0.001). Using multivariate logistic regression, we found that factors associated with DNR status were gender (OR 1.477, p=0.358, note interaction term), POA status (OR 6.612, p<0.001), LW (18.032, p<0.001), age (65–74 years OR 1.261, p=0.478; 75–84 years OR 1.737, p=0.091, >84 years OR 5.258, P<0.001), with interactions between POA and gender (OR 0.294, P=0.016) and between POA and LW (OR 0.227, p<0.005). Secondary analysis demonstrated that DNR orders were not significantly associated with death during admission (p=0.084). Conclusion Age, gender, POA, and LW use are predictors of ECF patient DNR use. Further, DNR presence is not a predictor of death in the hospital. PMID:26759640

    Advance directives (AD) were developed to respect patient autonomy. However, very few patients have AD, even in cases when major cardiovascular surgery is to follow. To understand the reasons behind the low prevalence of AD and to help decision making when patients are incompetent, it is necessary to focus on the impact of prehospital practitioners, who may contribute to an increase in AD by discussing them with patients. The purpose of this study was to investigate self-rated communication skills and the attitudes of physicians potentially involved in the care of cardiovascular patients toward AD.Self-administered questionnaires were sent to general practitioners, cardiologists, internists, and intensivists, including the Quality of Communication Score, divided into a General Communication score (QOCgen 6 items) and an End-of-life Communication score (QOCeol 7 items), as well as questions regarding opinions and practices in terms of AD.One hundred sixty-four responses were received. QOCgen (mean (±SD)): 9.0/10 (1.0); QOCeol: 7.2/10 (1.7). General practitioners most frequently start discussions about AD (74/149 [47%]) and are more prone to designate their own specialty (30/49 [61%], P < 0.0001). Overall, only 57/159 (36%) physicians designated their own specialty; 130/158 (82%) physicians ask potential cardiovascular patients if they have AD and 61/118 (52%) physicians who care for cardiovascular patients talk about AD with some of them.The characteristics of physicians who do not talk about AD with patients were those who did not personally have AD and those who work in private practices.One hundred thirty-three (83%) physicians rated the systematic mention of patients' AD in the correspondence between physicians as good, while 114 (71%) at the patients' first registration in the private practice.Prehospital physicians rated their communication skills as good, whereas end-of-life communication was rated much lower. Only half of those surveyed speak about AD

    Ibañez, Gladys E.; Levi-Minzi, Maria A.; Rigg, Khary K.; Mooss, Angela D.

    2013-01-01

    Background Benzodiazepines (BZ) are often diverted from legal sources to illicit markets at various points in the distribution process which begins with a pharmaceutical manufacturer, followed by distribution to healthcare providers, and finally, to the intended users. Little is known about the extent of BZ diversion involving distribution points directly related to healthcare sources (e.g., a script doctor) as opposed to points further down the distribution chain (e.g., street dealers). The present study examines the scope of BZ diversion via mechanisms directly related to a healthcare source. It examines the association between BZ dependence and the direct utilization of particular healthcare-related diversion sources among a diverse sample of prescription drug abusers in South Florida. Method Cross-sectional data were collected from five different groups of drug users: methadone-maintenance clients (n = 247), street drug users (n = 238), public-pay treatment clients (n = 246), private-pay treatment clients (n = 228), and stimulant using men who have sex with men (MSM; n = 248). Results Findings suggest that those ages 26 to 35 years old, non-Hispanic White participants, private-pay treatment clients, those who are insured, and those with higher incomes had higher odds of utilizing healthcare diversion sources. Participants utilized a pharmacy as a diversion source more than other healthcare sources of diversion, and the highest number of BZs were obtained from doctor shopping compared to other diversion sources. Those who reported BZ dependence also had 2.5 times greater odds of using a healthcare source to obtain BZs than those who did not meet criteria for dependence. Discussion Prevention of BZ diversion through healthcare sources should include strategies to reduce doctor shopping and diversion from pharmacies. PMID:23662331

    2016-01-01

    Context: To ensure patient-centered end-of-life care, advance care planning (ACP) must be documented in the medical record and readily retrieved across care settings. Objective: To describe use of the Care Directives Activity tab (CDA), a single-location feature in the electronic health record for collecting and viewing ACP documentation in inpatient and ambulatory care settings, and to assess its association with ACP documentation rates. Design: Retrospective pre- and postimplementation analysis in 2012 and 2013 at Kaiser Permanente Southern California among 113,309 patients aged 65 years and older with ACP opportunities during outpatient or inpatient encounters. Main Outcome Measures: Providers’ CDA use rates and documentation rates of advance directives and physician orders for life-sustaining treatments stratified by CDA use. Results: Documentation rates of advance directives and physician orders for life-sustaining treatments among patients with outpatient and inpatient encounters were 3.5 to 9.6 percentage points higher for patients with CDA use vs those without it. The greatest differences were for orders for life-sustaining treatments among patients with inpatient encounters and for advance directives among patients with outpatient encounters; both were 9.6 percentage points higher among those with CDA use than those without it. All differences were significant after controlling for yearly variation (p < 0.001). Conclusion: Statistically significant differences in documentation rates between patients with and without CDA use suggest the potential of a standardized location in the electronic health record to improve ACP documentation. Further research is required to understand effects of CDA use on retrieval of preferences and end-of-life care. PMID:27057820

    Hepatocellular carcinoma (HCC) can be lethal due to its aggressive course and lack of effective systemic therapies for advanced disease. Sorafenib is the only systemic therapy that has demonstrated an overall survival benefit in patients with advanced HCC, and new agents for treatment of advanced HCC are needed. The multiple pathways involved in HCC oncogenesis, proliferation and survival provide many opportunities for the development of molecularly targeted therapies. Molecular targets of interest have expanded from angiogenesis to cancer cell-directed oncogenic signaling pathways for treatment of advanced HCC. Agents targeting vascular endothelial growth factor receptor, epidermal growth factor receptor, fibroblast growth factor receptor, platelet-derived growth factor receptor, c-mesenchymal-epithelial transition factor-1 and mammalian target of rapamycin signaling have been actively explored. This article focuses on the evaluation of molecular agents targeting pathogenic HCC and provides a review of recently completed phase III drug studies (e.g. involving sorafenib, sunitinib, brivanib, linifanib, erlotinib, everolimus, ramucirumab or orantinib) and ongoing drug studies (e.g. involving lenvatinib, regorafenib, tivantinib or cabozantinib) of molecularly targeted agents in advanced HCC, including a brief description of the biologic rationale behind these agents.

    Medical healthcare for refugees is strictly regulated by law in Germany but the great regional variation in the implementation is currently a huge challenge for healthcare providers. Providers are often not familiar with the specific local regulations and especially in emergencies it is often not possible to clarify open questions before treating patients. The high influx of refugees in the summer and fall of 2015 led to a situation that could only be managed with the voluntary and pragmatic help of all healthcare personnel involved. This article explains the most relevant regulations covering medical healthcare for refugees and asylum seekers. In addition, the procedure for the approval of asylum status in itself can have a direct or indirect impact on the health status of these individuals; therefore, some comments are made regarding this aspect.

    2015-12-01

    This article reviews the current situation regarding the provision of education and training for healthcare clinical support workers (HCSWs). In the UK, there has been an increasing reliance on unqualified clinical support staff to provide a significant proportion of the direct patient care in all healthcare settings. HCSWs routinely undertake several nursing activities that were traditionally the responsibility of nursing students or junior staff nurses. There is a need for an urgent review of the training of healthcare support staff. A 'tick box' approach to training, with an emphasis on classroom-based or on-the-job learning, makes it difficult for HCSWs to integrate theory into practice, and supports a transactional approach to caring rather than a relational approach to caregiving. Lessons from the educational experiences of other healthcare groups should be applied to the training of HCSWs. An immersive, participatory teaching and learning strategy is one approach that could be used. PMID:26647705

    2016-07-01

    This article examines current trends and prospects in Finnish healthcare literature and discussion. The Finnish healthcare system was long considered to manifest an equal, universal, and solidaristic welfare scheme. However, recent data reveals structural inequalities in access to healthcare that result in health differences among socioeconomic groups. The political will aims at tackling these inequalities, but the ideological trend toward responsibilization of the individual taking place across political spheres elsewhere in Europe creates potential challenges to this goal. The applications of this trend have a theoretical background in the responsibility-sensitive egalitarian-or luck egalitarian-tradition. The theory, which is unfit for real-life policy applications, has explicit appeal in considerations aiming at the responsibilization of the individual within the healthcare sector. It remains to be seen in which direction the Finnish welfare schemes will continue to develop. PMID:27348829

    Purpose - The purpose of this paper is to present the results of exploratory research designed to develop an awareness of healthcare behaviors, with a view toward improving the customer satisfaction with healthcare services. It examines the relationship between healthcare providers and their consumers/patients/clients. Design/methodology/approach - The study uses a critical incident methodology, with both effective and ineffective behavioral specimens examined across different provider groups. Findings - The effects of these different behaviors on what Berry (1999) identified as the common core values of service organizations are examined, as those values are required to build a lasting service relationship. Also examined are categories of healthcare practice based on the National Quality Strategy priorities. Research limitations/implications - The most obvious is the retrospective nature of the method used. How accurate are patient or consumer memories? Are they capable of making valid judgments of healthcare experiences (Berry and Bendapudi, 2003)? While an obvious limitation, such recollections are clearly important as they may be paramount in following the healthcare practitioners' instructions, loyalty for repeat business, making recommendations to others and the like. Further, studies have shown retrospective reports to be accurate and useful (Miller et al., 1997). Practical implications - With this information, healthcare educators should be in a better position to improve the training offered in their programs and practitioners to better serve their customers. Social implications - The findings would indicate that the human values of excellence, innovation, joy, respect and integrity play a significant role in building a strong service relationship between consumer and healthcare provider. Originality/value - Berry (1999) has argued that the overriding importance in building a lasting service business is human values. This exploratory study has shown how

This study sets out to apply and test the Unified Theory of Acceptance and Use of Technology (UTAUT), to examine the factors influencing healthcare Information Technology (IT) services. A structured questionnaire was developed and distributed to healthcare representatives in each province surveyed in Thailand. Data collected from 400 employees including physicians, nurses, and hospital staff members were tested the model using structural equation modeling technique. The results found that the factors with a significant effect are performance expectancy, effort expectancy and facilitating conditions. They were also found to have a significant impact on behavioral intention to use the acceptance healthcare technology. In addition, in Thai provincial areas, positive significance was found with two factors: social influence on behavioral intention and facilitating conditions to direct using behavior. Based on research findings, in order for healthcare information technology to be widely adopted and used by healthcare staffs in healthcare supply chain management, the healthcare organizational management should improve healthcare staffs' behavioral intention and facilitating conditions.

    The inherent electro-optical properties of gallium arsenide (GaAs) and related III-V compounds make this class of semiconductors an optimum choice for use in very high efficiency solar cells. The ability to alloy GaAs with other column III and V elements while maintaining the single crystal zincblende structure allows the photovoltaic properties to be tailored to specific needs. The current understanding and control of the properties of these materials is more advanced than for any other semiconductor except single crystal silicon. For these reasons, the Advanced High Efficiency Concepts Program supports materials research to improve the properties of III-V semiconductors needed to achieve the maximum attainable photovoltaic conversion efficiencies.

    Lipcamon, James D; Mainwaring, Brian A

    2004-01-01

    Conflict causes decided tension in the workplace and often produces poor professional outcomes. A manager dealing with conflict can experience a crisis of confidence and often ends up second-guessing himself or herself, regardless of how a situation has been handled. In some organizations, conflict is not viewed positively or as an opportunity for improvement. In these organizations, most individuals will see conflict as being unproductive, unpleasant, and a waste of time and energy. Yet, conflict provides employees with critical feedback on how things are going. When viewed in a positive context, even personality conflicts may provide information to the healthcare manager about what is not working in the organization. If conflict is not directed and controlled, it can have damaging effects in the workplace, stifling the growth of departments and deflating employee morale. Our job as healthcare managers is to deal with conflict so that it does not decrease productivity or detract from the provision of patient-centered care. There are 4 general sources for interpersonal conflict: personal differences, informational deficiency, role incompatibility, and environmental stress. There are 5 common responses used in dealing with conflict: forcing, accommodating, avoiding, compromising, and collaborating. Healthcare managers should become comfortable with using all of these approaches. PMID:15259690

    Efforts to ensure effective participation of patients in healthcare are called by many names—patient centredness, patient engagement, patient experience. Improvement initiatives in this domain often resemble the efforts of manufacturers to engage consumers in designing and marketing products. Services, however, are fundamentally different than products; unlike goods, services are always ‘coproduced’. Failure to recognise this unique character of a service and its implications may limit our success in partnering with patients to improve health care. We trace a partial history of the coproduction concept, present a model of healthcare service coproduction and explore its application as a design principle in three healthcare service delivery innovations. We use the principle to examine the roles, relationships and aims of this interdependent work.

    Purpose To perform the first meta-analysis of the efficacy of skin-directed therapies for cutaneous metastases. Methods MEDLINE, EMBASE, The Cochrane Library, and ClinicalTrials.gov databases were searched for reports of prospective clinical studies published between 1960 and 2013 that assessed the response of skin-directed therapy for cutaneous metastases (47 of 2,955 unique studies were selected). Primary end points of the study were complete and objective response rates. Secondary analyses were preplanned and included subgroup analyses by skin-directed therapy, histology, and recurrence rates. Meta-analyses were performed with random-effect modeling, and extent of heterogeneity between studies was determined with the Cochran Q and I2 tests. Results After applying exclusion criteria, 47 prospective studies of 4,313 cutaneous metastases were assessed. Five skin-directed therapies were identified: electrochemotherapy, photodynamic therapy, radiotherapy, intralesional therapy, and topical therapy. Among all cutaneous metastases, complete response rate was 35.5% (95% CI, 27.6% to 44.3%) and objective response rate was 60.2% (95% CI, 50.6% to 69.0%). Overall recurrence rate was estimated to be 9.2% (95% CI, 3.7% to 21.2%). Melanoma and breast carcinoma comprised 96.8% of all cutaneous metastases studied and had similar objective response rates (54.5% [95% CI, 48.3% to 60.7%] and 54.0% [95% CI, 48.3% to 59.7%], respectively). Grade ≥ 3 toxicity was reported in less than 6% of patients. Conclusion Response to skin-directed therapy for cutaneous metastases is high but heterogeneous across treatment modalities, with low rates of recurrence post-treatment. Treatment was generally well tolerated and conferred improvements in quality of life. Standardization of response criteria for cutaneous metastases and treatment algorithms to optimally use the available skin-directed therapies are needed. PMID:25154827

    The template-directed strategy is a powerful method to construct porphyrin nanorings with high complexities, wherein metalloporphyrin precursors pre-organize via supramolecular interactions of the porphyrin or its central metal with a carefully selected template, and then react with each other to deliver a final cyclic multiporphyrin structure. In this article, we review the recent breakthroughs in the template-directed synthesis methods and new structures of porphyrin or metalloporphyrin nanorings, as well as their applications in host-guest chemistry and artificial light-harvesting.

    Background The effective and timely integration of the best available research evidence into healthcare practice has considerable potential to improve the quality of provided care. Knowledge translation (KT) approaches aim to develop, implement, and evaluate strategies to address the research-practice gap. However, most KT research has been directed toward implementation strategies that apply cognitive, behavioral, and, to a lesser extent, organizational theories. In this paper, we discuss the potential of institutional theory to inform KT-related research. Discussion Despite significant research, there is still much to learn about how to achieve KT within healthcare systems and practices. Institutional theory, focusing on the processes by which new ideas and concepts become accepted within their institutional environments, holds promise for advancing KT efforts and research. To propose new directions for future KT research, we present some of the main concepts of institutional theory and discuss their application to KT research by outlining how institutionalization of new practices can lead to their ongoing use in organizations. In addition, we discuss the circumstances under which institutionalized practices dissipate and give way to new insights and ideas that can lead to new, more effective practices. Summary KT research informed by institutional theory can provide important insights into how knowledge becomes implemented, routinized, and accepted as institutionalized practices. Future KT research should employ both quantitative and qualitative research designs to examine the specifics of sustainability, institutionalization, and deinstitutionalization of practices to enhance our understanding of these complex constructs.

    Healthcare is one of the business fields with the highest Big Data potential. According to the prevailing definition, Big Data refers to the fact that data today is often too large and heterogeneous and changes too quickly to be stored, processed, and transformed into value by previous technologies. The technological trends drive Big Data: business processes are more and more executed electronically, consumers produce more and more data themselves - e.g. in social networks - and finally ever increasing digitalization. Currently, several new trends towards new data sources and innovative data analysis appear in medicine and healthcare. From the research perspective, omics-research is one clear Big Data topic. In practice, the electronic health records, free open data and the "quantified self" offer new perspectives for data analytics. Regarding analytics, significant advances have been made in the information extraction from text data, which unlocks a lot of data from clinical documentation for analytics purposes. At the same time, medicine and healthcare is lagging behind in the adoption of Big Data approaches. This can be traced to particular problems regarding data complexity and organizational, legal, and ethical challenges. The growing uptake of Big Data in general and first best-practice examples in medicine and healthcare in particular, indicate that innovative solutions will be coming. This paper gives an overview of the potentials of Big Data in medicine and healthcare. PMID:26063521

    In the Advance Coal Liquefaction Concept Proposal (ACLCP) carbon monoxide (CO) and water have been proposed as the primary reagents in the pretreatment process. The main objective of this project is to develop a methodology for pretreating coal under mild conditions based on a combination of existing processes which have shown great promise in liquefaction, extraction and pyrolysis studies. The aim of this pretreatment process is to partially depolymerise the coal, eliminate oxygen and diminish the propensity for retograde reactions during subsequent liquefaction. The desirable outcome of the CO pretreatment step should be: (1) enhanced liquefaction activity and/or selectivity toward products of higher quality due to chemical modification of the coal structure; (2) cleaner downstream products; (3) overall improvement in operability and process economics.

    Red blood cell transfusion is an effective method to treat acute hemorrhage and severe anemia. However, blood source from donors is very limited, and transfusion-transmitted diseases occurred frequently, thus threatening human health. Therefore, the safe, abundant and functional blood source is needed. Generation of blood cells from human pluripotent stem cells(hPSC) will offer alternative approach. Lots of studies have been focused on erythroid cell differentiation in vitro, including how to enhance efficiency and improve their function. In this review, the research advances on differentiation methods and the regulatory mechanism are summarized. In addition, the progress in PSC differentiation into erythrocytes and the problems to be solved are discussed briefly. PMID:24598681

    Several studies found that direct instruction and task structuring can effectively promote children's ability to design unconfounded experiments. The present study examined whether the impact of these interventions extends to other scientific reasoning skills by comparing the inquiry activities of 55 fifth-graders randomly assigned to one of three conditions. Children in the control condition investigated a four-variable inquiry task without additional support. Performance of this task in the direct instruction condition was preceded by a short training in experimental design, whereas children in the task structuring condition, who did not receive the introductory training, were given a version of the task that addressed the four variables one at a time. Analysis of children's experimentation behavior confirmed that direct instruction and task structuring are equally effective and superior to unguided inquiry. Both interventions also evoked more determinate predictions and valid inferences. These findings demonstrate that the effect of short-term interventions designed to promote unconfounded experimentation extends beyond the control of variables.

    Mobile phones are becoming increasingly important in monitoring and delivery of healthcare interventions. They are often considered as pocket computers, due to their advanced computing features, enhanced preferences and diverse capabilities. Their sophisticated sensors and complex software applications make the mobile healthcare (m-health) based applications more feasible and innovative. In a number of scenarios user-friendliness, convenience and effectiveness of these systems have been acknowledged by both patients as well as healthcare providers. M-health technology employs advanced concepts and techniques from multidisciplinary fields of electrical engineering, computer science, biomedical engineering and medicine which benefit the innovations of these fields towards healthcare systems. This paper deals with two important aspects of current mobile phone based sensor applications in healthcare. Firstly, critical review of advanced applications such as; vital sign monitoring, blood glucose monitoring and in-built camera based smartphone sensor applications. Secondly, investigating challenges and critical issues related to the use of smartphones in healthcare including; reliability, efficiency, mobile phone platform variability, cost effectiveness, energy usage, user interface, quality of medical data, and security and privacy. It was found that the mobile based applications have been widely developed in recent years with fast growing deployment by healthcare professionals and patients. However, despite the advantages of smartphones in patient monitoring, education, and management there are some critical issues and challenges related to security and privacy of data, acceptability, reliability and cost that need to be addressed.

    India is undergoing a rapid transformation in terms of governance, administrative reforms, newer policy develoment, and social movements. India is also considered one of the most vibrant economies in the world. The current discourse in public space is dominated by issues such as economic development, security, corruption free governance, gender equity, and women safety. Healthcare though remains a pressing need of population; seems to have taken a backseat. In the era of decreasing subsidies and cautious investment in social sectors, the 2(nd) National Conference on Family Medicine and Primary Care 2015 (FMPC) brought a focus on "healthcare" in India. The theme of this conference was "Healthcare is Primary." The conference participants discussed on the theme of why healthcare should be a national priority and why strong primary care should remain at the center of healthcare delivery system. The experts recommended that India needs to strengthen the "general health system" instead of focusing on disease based vertical programs. Public health system should have capacity and skill pool to be able to deliver person centered comprehensive health services to the community. Proactive implementation of policies towards human resource in health is the need of the hour. As the draft National Health Policy 2015 is being debated, "family medicine" (academic primary care), the unfinished agenda of National Health Policy 2002, remains a priority area of implementation.

    The state of health communication for a given population is a function of several tiers of structure and process: government policy, healthcare directives, healthcare structure and process, and the ethnosocial realities of a multicultural society. Common yet specific to these tiers of health communication is the interpersonal and intergroup use of language in all its forms. Language is the most common behavior exhibited by humankind. Its use at all tiers determines quality of healthcare and quality of life for healthcare consumers: patients and their families. Of note, at the consumer end, mounting evidence demonstrates that barriers to health communication contribute to poorer access to care, quality of care, and health outcomes. The lack of comprehensible and usable written and spoken language is a major barrier to health communication targeting primary and secondary disease prevention and is a major contributor to the misuse of healthcare, patient noncompliance, rising healthcare costs. In this paper, we cursorily examine the relationship among government policy, institutional directives, and healthcare structure and process and its influence on the public health, especially vulnerable populations. We conclude that limited health communication in the context of changing healthcare environments and diverse populations is an important underpinning of rising healthcare costs and sustained health disparities. More research is needed to improve communication about health at all tiers and to develop health communication interventions that are usable by all population groups. PMID:15208522

    2015-01-01

    For people with Bipolar Affective Disorder, a self-binding (advance) directive (SBD), by which they commit themselves to treatment during future episodes of mania, even if unwilling, can seem the most rational way to deal with an imperfect predicament. Knowing that mania will almost certainly cause enormous damage to themselves, their preferred solution may well be to allow trusted others to enforce treatment and constraint, traumatic though this may be. No adequate provision exists for drafting a truly effective SBD and efforts to establish such provision are hampered by very valid, but also paralysing ethical, clinical and legal concerns. Effectively, the autonomy and rights of people with bipolar are being 'protected' through being denied an opportunity to protect themselves. From a standpoint firmly rooted in the clinical context and experience of mania, this article argues that an SBD, based on a patient-centred evaluation of capacity to make treatment decisions (DMC-T) and grounded within the clinician-patient relationship, could represent a legitimate and ethically coherent form of self-determination. After setting out background information on fluctuating capacity, mania and advance directives, this article proposes a framework for constructing such an SBD, and considers common objections, possible solutions and suggestions for future research.

    Direct-write technologies, a subset of the rapid prototyping, have been applied for many applications including electronics, photonics and biomedical engineering. Among them, Micropen(TM) is a promising technique, providing precision deposition of materials with various viscosities, on-line design changes and writing on nonplanar substrates. The objective of this project was to directly write two- and three-dimensional novel structures by Micropen(TM) for potential optical and transducer applications. First, to gain a basic understanding of Micropen(TM) operation, poly(methyl methacrylate) (PMMA) solutions were developed as a model system. The effects of solution rheological properties on deposition conditions were investigated. Secondly, PMMA/SiO2 hybrids were developed using sol-gel process. The effects of organic/inorganic ratios on thermal stability, microstructure and optical properties were studied. The solution with 80 wt% PMMA loading was chosen to deposit lines for optical applications. Another application was the direct-write of lead zirconate titanate (PZT) thick films (6-70 mum) for MEMS or high frequency medical imaging applications. Pastes consisting of 15-30 vol% ceramic loading in a sol-gel solution were prepared for the deposition of films on various substrates. The PZT sol was used as a binder as well as to achieve low temperature heat treatment of the films. Using the 15 vol% paste with a 250-mum pen tip, a four-layer film was deposited on a silicon substrate. This 16-mum film with 1 cm 2 area had K of 870, tandelta of 4.1%, Pr of 12.2 muC/cm 2 and Ec of 27 kV/cm. Furthermore, Micropen(TM) was utilized for the direct-write of ceramic skeletal structures to develop PZT ceramic/polymer composites with 2-2 connectivity for medical ultrasound transducers. Ceramic/binder based pastes were developed as writing materials. The 35 vol% paste exhibited shear thinning with a viscosity of 45 Pa˙s at lower shear rate and 3 Pa˙s at higher shear rate. Using a

    Nowadays, severe infection has become one of the common problems in clinic. The morbidity of severe sepsis and septic shock is increasing, which becomes a big threat to patients with burn wounds or chronic diseases. It has become a key subject about how to cure severe sepsis and septic shock. In recent years, mortality of patients in such condition has declined slightly, which might be attributed to the application of early goal-directed therapy (EGDT) in certain degree. This article reviews application of EGDT in severe sepsis and septic shock, in order to analyze its effectiveness and boundedness, as well as predict its development. PMID:27188487

    2012-01-01

    Autism Spectrum Disorder (ASD) refers to a group of heterogeneous neurodevelopmental disorders that are unified by impairments in reciprocal social communication and a pattern of inflexible behaviors. Recent genetic advances have resolved some of the complexity of the genetic architecture underlying ASD by identifying several genetic variants that contribute to the disorder. Different etiological pathways associated with ASD may converge through effects on common molecular mechanisms, such as synaptogenesis, neuronal motility, and axonal guidance. Recently, with more sophisticated techniques, neuroimaging, and neuropathological studies have provided some consistency of evidence that altered structure, activity, and connectivity within complex neural networks is present in ASD, compared to typically developing children. The imaging-genetics approach promises to help bridge the gap between genetic variation, resultant biological effects on the brain, and production of complex neuropsychiatric symptoms. Here, we review recent findings from the developing field of imaging-genetics applied to ASD. Studies to date have indicated that relevant risk genes are associated with alterations in circuits that mediate socio-emotional, visuo-spatial, and language processing. Longitudinal studies ideally focused on early development, in conjunction with investigation for gene–gene, and gene–environment interactions may move the promise of imaging-genetics in ASD closer to the clinical domain.

    OBJECTIVES: A useful framework for initiating organ donation discussions in the primary care setting may help increase willingness to donate and thereby increase the frequency of organ transplantation. Given the lower willingness to donate among African Americans and that a higher proportion of African Americans die while waiting for an organ transplant, this is an important group to consider in such an approach. We examined the association among completion of a living will and willingness to donate and the influence of race in this relationship. METHODS: A nationwide telephone interview survey using random digit dialing of households in high- and low-density African-American census blocks. Results: One hundred-eighty-eight adults participated (41% cooperation rate). In a multivariate model, factors associated with willingness to donate included having signed a living will (OR=2.43, 95% CI=1.13-5.23), talking with a physician about organ donation (OR=3.04, 95% CI=1.07-8.67) and white race (OR=2.5, 95% CI=1.23-5). CONCLUSION: The public is generally supportive of organ donation although African Americans remain less willing to donate after controlling for confounding variables. Physicians interested in increasing donation rates should consider incorporating organ donation into discussions of advance care planning and end-of-life care. PMID:16775911

    Thermal barrier coatings will be more aggressively designed to protect gas turbine engine hot-section components in order to meet future engine higher fuel efficiency and lower emission goals. In this presentation, thermal barrier coating development considerations and performance will be emphasized. Advanced thermal barrier coatings have been developed using a multi-component defect clustering approach, and shown to have improved thermal stability and lower conductivity. The coating systems have been demonstrated for high temperature combustor applications. For thermal barrier coatings designed for turbine airfoil applications, further improved erosion and impact resistance are crucial for engine performance and durability. Erosion resistant thermal barrier coatings are being developed, with a current emphasis on the toughness improvements using a combined rare earth- and transition metal-oxide doping approach. The performance of the toughened thermal barrier coatings has been evaluated in burner rig and laser heat-flux rig simulated engine erosion and thermal gradient environments. The results have shown that the coating composition optimizations can effectively improve the erosion and impact resistance of the coating systems, while maintaining low thermal conductivity and cyclic durability. The erosion, impact and high heat-flux damage mechanisms of the thermal barrier coatings will also be described.

This is accomplished by guaranteeing conformance to all requirements, standards, procedures, and regulations. These assurance processes are even more important when coupled with healthcare software systems, embedded software in medical instrumentation, and other healthcare-oriented life-critical systems. The current Food and Drug Administration (FDA) regulatory requirements and guidance documentation do not address certain aspects of complete software assurance activities. In addition, the FDA’s software oversight processes require enhancement to include increasingly complex healthcare systems such as Hospital Information Systems (HIS).

    Patient queues are prevalent in healthcare and wait time is one measure of access to care. We illustrate Queueing Theory-an analytical tool that has provided many insights to service providers when designing new service systems and managing existing ones. This established theory helps us to quantify the appropriate service capacity to meet the patient demand, balancing system utilization and the patient's wait time. It considers four key factors that affect the patient's wait time: average patient demand, average service rate and the variation in both. We illustrate four basic insights that will be useful for managers and doctors who manage healthcare delivery systems, at hospital or department level. Two examples from local hospitals are shown where we have used queueing models to estimate the service capacity and analyze the impact of capacity configurations, while considering the inherent variation in healthcare.

    With recent theoretical and empirical research in basic and applied psychology, human factors, and engineering, it is now sufficient to define an integrated approach to the deign of advanced displays for present and future nuclear power plants. Traditionally, the conventional displays have shown operators the individual variables on gauges, meters, strip charts, etc. This design approach requires the operators to mentally integrate the separately displayed variables and determine the implications for the plant state. This traditional approach has been known as the single-sensor-single-indicator display design and it places an intolerable amount of mental workload on operators during transients and abnormal conditions. This report discusses a new alternative approach which is the use of direct perception interfaces. Direct perception a interfaces display the underlying physical and system constraints of the situation in a directly perceptual way, such that the viewer need not reason about what is seen to identify system states, but can identify the state of the system perceptually. It is expected that displays which show the dynamics of fundamental physical laws should better support operator decisions and diagnoses of plant states. The purpose of this research project is to develop a suite of direct perception displays for PWR nuclear power plant operations.

    We examined skill-based differences in the anticipation of ball direction during the catching of a grounder in baseball. In Experiment 1, we used film stimuli which included a sequence of pitching and hitting action from the shortstop's customary perspective, and participants judged the ball's direction (left or right). Also, we used white-circle stimuli, and participants reported whether the circle was displaced to the left or to the right. Baseball players responded faster than non-players in the film task, but there was no significant difference between the two groups in the white-circle task. In Experiment 2, we used film stimuli which were cut off at four different temporal occlusion periods to examine the time of extraction of important visual cues. Accuracy exceeded the chance level prior to the bat-ball contact in both groups, but was earlier for players than for non-players. Our results suggest that players may extract anticipatory visual cues more effectively and earlier than non-players. PMID:23012821

    Directed self-assembly (DSA) has the potential to extend scaling for both line/space and hole patterns. DSA has shown the capability for pitch reduction (multiplication), hole shrinks, CD self-healing as well as a pathway towards LWR and pattern collapse improvement [1-10]. TEL has developed a DSA development ecosystem (collaboration with customers, consortia, inspection vendors and material suppliers) to successfully demonstrate directed PS-PMMA DSA patterns using chemo-epitaxy (lift-off and etch guide) and grapho-epitaxy integrations on 300 mm wafers. New processes are being developed to simplify process integration, to reduce defects and to address design integration challenges with the long term goal of robust manufacturability. For hole DSA applications, a wet development process has been developed that enables traditional post-develop metrology through the high selectivity removal of PMMA cylindrical cores. For line/ space DSA applications, new track, cleans and etch processes have been developed to improve manufacturability. In collaboration with universities and consortia, fundamental process studies and simulations are used to drive process improvement and defect investigation. To extend DSA resolution beyond a PS-PMMA system, high chi materials and processes are also explored. In this paper, TEL's latest process solutions for both hole and line/space DSA process integrations are presented.

    2006-04-04

    A new class of hybrid organic-inorganic materials, and methods of synthesis, that can be used as a proton exchange membrane in a direct methanol fuel cell. In contrast with Nafion.RTM. PEM materials, which have random sulfonation, the new class of materials have ordered sulfonation achieved through self-assembly of alternating polyimide segments of different molecular weights comprising, for example, highly sulfonated hydrophilic PDA-DASA polyimide segment alternating with an unsulfonated hydrophobic 6FDA-DAS polyimide segment. An inorganic phase, e.g., 0.5 5 wt % TEOS, can be incorporated in the sulfonated polyimide copolymer to further improve its properties. The new materials exhibit reduced swelling when exposed to water, increased thermal stability, and decreased O.sub.2 and H.sub.2 gas permeability, while retaining proton conductivities similar to Nafion.RTM.. These improved properties may allow direct methanol fuel cells to operate at higher temperatures and with higher efficiencies due to reduced methanol crossover.

    A comprehensive understanding of the quantities and characteristics of the material that needs to be managed is one of the most basic steps in the development of a plan for solid waste management. In this case, the material under consideration is the solid waste generated in healthcare facilities, also known as healthcare waste. Unfortunately, limited reliable information is available in the open literature on the quantities and characteristics of the various types of wastes that are generated in healthcare facilities. Thus, sound management of these wastes, particularly in developing countries, often is problematic. This article provides information on the quantities and properties of healthcare wastes in various types of facilities located in developing countries, as well as in some industrialized countries. Most of the information has been obtained from the open literature, although some information has been collected by the authors and from reports available to the authors. Only data collected within approximately the last 15 years and using prescribed methodologies are presented. The range of hospital waste generation (both infectious and mixed solid waste fractions) varies from 0.016 to 3.23kg/bed-day. The relatively wide variation is due to the fact that some of the facilities surveyed in Ulaanbaatar include out-patient services and district health clinics; these facilities essentially provide very basic services and thus the quantities of waste generated are relatively small. On the other hand, the reported amount of infectious (clinical, yellow bag) waste varied from 0.01 to 0.65kg/bed-day. The characteristics of the components of healthcare wastes, such as the bulk density and the calorific value, have substantial variability. This literature review and the associated attempt at a comparative analysis point to the need for worldwide consensus on the terms and characteristics that describe wastes from healthcare facilities. Such a consensus would greatly

    This paper presents the results of a study to determine the directions that electric propulsion technology should take to meet the primary propulsion requirements for earth-orbital missions of the next three decades in the most cost-effective manner. Discussed are the mission set requirements, state-of-the-art electric propulsion technology and the baseline system characterized by it, adequacy of the baseline system to meet the mission set requirements, cost-optimum electric propulsion system characteristics for the mission set, and sensitivities of mission costs and design points to system-level electric propulsion parameters. It is found that the efficiency-specific impulse characteristic generally has a more significant impact on overall costs than specific masses or costs of propulsion and power systems.

  11. Advancing lignocellulose bioconversion through direct assessment of enzyme action on insoluble substrates.

    Microbial utilization of lignocellulose from plant cell walls is integral to carbon cycling on Earth. Correspondingly, secreted enzymes that initiate lignocellulose depolymerization serve a crucial step in the bioconversion of lignocellulosic biomass to fuels and chemicals. Genome and metagenome sequencing efforts that span the past decade reveal the diversity of enzymes that have evolved to transform lignocellulose from wood, herbaceous plants and grasses. Nevertheless, there are relatively few examples where 'omic' technologies have identified novel enzyme activities or combinations thereof that dramatically improve the economics of lignocellulose bioprocessing and utilization. A likely factor contributing to the discrepancy between sequence-based enzyme discovery and enzyme application is the common practice to screen enzyme candidates based on activity measurements using soluble model compounds. In this context, the development and application of imaging, physicochemical, and spectromicroscopic techniques that allow direct assessment of enzyme action on relevant lignocellulosic substrates is reviewed.

    Personal and professional values of healthcare practitioners influence their clinical decisions. Understanding these values for individuals and across healthcare professions can help improve patient-centred decision-making by individual practitioners and interprofessional teams, respectively. We aimed to identify these values and integrate them into a single framework using Schwartz's values model. We searched Medline, Embase, PsycINFO, CINAHL and ERIC databases for articles on personal and professional values of healthcare practitioners and students. We extracted values from included papers and synthesized them into a single framework using Schwartz's values model. We summarised the framework within the context of healthcare practice. We identified 128 values from 50 included articles from doctors, nurses and allied health professionals. A new framework for the identified values established the following broad healthcare practitioner values, corresponding to Schwartz values (in parentheses): authority (power); capability (achievement); pleasure (hedonism); intellectual stimulation (stimulation); critical-thinking (self-direction); equality (universalism); altruism (benevolence); morality (tradition); professionalism (conformity); safety (security) and spirituality (spirituality). The most prominent values identified were altruism, equality and capability. This review identified a comprehensive set of personal and professional values of healthcare practitioners. We integrated these into a single framework derived from Schwartz's values model. This framework can be used to assess personal and professional values of healthcare practitioners across professional groups, and can help improve practitioners' awareness of their values so they can negotiate more patient-centred decisions. A common values framework across professional groups can support shared education strategies on values and help improve interprofessional teamwork and decision-making. PMID:26215664

  13. Future directions in risk stratification and therapy for advanced pediatric genitourinary rhabdomyosarcoma.

    2016-02-01

    Rhabdomyosarcoma (RMS) represents the most common soft tissue sarcoma in infants and children and the third most common pediatric solid tumor, accounting for 5% to 15% of all childhood solid tumors. Of these, 15% to 20% arise from the genitourinary tract, with the most common sites originating from the prostate, bladder, and paratesticular regions, followed by the vagina and uterus. Although upfront radical surgery was used at the initiation of Intergroup RMS Study-I (1972-1978), the treatment paradigm has shifted to include initial biopsy with the goal of organ preservation, systemic chemotherapy for all patients, and local control involving surgical resection with or without radiation therapy for most patients. Collaborative group clinical trials have led to dramatic improvement in survival rates from 1960 to 1996 among patients with low- or intermediate-risk disease; however, outcomes appear to have plateaued in more recent years, and the prognosis for patients with metastatic or relapsed/refractory disease remains poor. Current management goals include minimizing toxicity while maintaining the excellent outcomes in low-risk disease, as well as improving outcomes in patients with intermediate- and high-risk disease. Advances in genetic analysis have allowed further refinement in risk stratification of patients. Perhaps the most significant recent development in RMS research was the discovery of an association of alveolar RMS (ARMS) with translocations t(2;13) and t(1;13). Translocation fusion-positive tumors comprise 80% of ARMS and are more aggressive. Fusion-negative ARMS may have a clinical course similar to embryonal RMS. Future Children's Oncology Group sarcoma studies will likely incorporate fusion status into risk stratification and treatment allocation. Newer radiotherapy modalities hold promise for providing local control of disease while minimizing morbidity. The addition of traditional cytotoxic chemotherapeutic agents does not seem to improve

    2013-01-01

    Advances in hydrogel design have revolutionized the way biomaterials are applied to address biomedical needs. Hydrogels were introduced in medicine over 50 years ago and have evolved from static, bioinert materials to dynamic, bioactive microenvironments, which can be used to direct specific biological responses such as cellular ingrowth in wound healing or on-demand delivery of therapeutics. Two general classes of mechanisms, those defined by the user and those dictated by the endogenous cells and tissues, can control dynamic hydrogel microenvironments. These highly tunable materials have provided bioengineers and biological scientists with new ways to not only treat patients in the clinic but to study the fundamental cellular responses to engineered microenvironments as well. Here, we provide a brief history of hydrogels in medicine and follow with a discussion of the synthesis and implementation of dynamic hydrogel microenvironments for healthcare-related applications.

    Background: The main purpose of this study was to identify factors that influence healthcare quality in the Iranian context. Methods: Exploratory in-depth individual and focus group interviews were conducted with 222 healthcare stakeholders including healthcare providers, managers, policy-makers, and payers to identify factors affecting the quality of healthcare services provided in Iranian healthcare organisations. Results: Quality in healthcare is a production of cooperation between the patient and the healthcare provider in a supportive environment. Personal factors of the provider and the patient, and factors pertaining to the healthcare organisation, healthcare system, and the broader environment affect healthcare service quality. Healthcare quality can be improved by supportive visionary leadership, proper planning, education and training, availability of resources, effective management of resources, employees and processes, and collaboration and cooperation among providers. Conclusion: This article contributes to healthcare theory and practice by developing a conceptual framework that provides policy-makers and managers a practical understanding of factors that affect healthcare service quality.

    2008-01-01

    In this report, the authors examine a major phenomenon in the Chinese healthcare marketplace: the explosion of a vigorous and demanding middle class and its impact on the future directions the industry should pursue. Little is known about the expectations of the middle class regarding their healthcare needs other than through anecdotal or informal sources. The views of the middle class are shaped by a variety of influences which include exposure through direct personal contact with international healthcare facilities when traveling abroad or indirectly through increased exposure to the entertainment industry with its abundance of hospital and medical dramas. In addition to a general increased international awareness arising from more advanced education, the perspective of the middle class consumer is also shaped by the reality of what is currently available in China and what is realistic to expect. This report addresses this lack of factual data through an extensive survey of middle class consumers in three major cities in China: Beijing, Shanghai and Chengdu. The survey took a practical and pragmatic approach to exploring this issue. No attempt was made in this study to explain why the consumer feels the way they do about their healthcare expectations. The purpose was simply to outline what expectations the middle class have for the healthcare marketplace in China. In some respects the results are not surprising. They are the expectations that people have in any country, any where. They expect greater privacy and dignity in the care-giving process. They want to be more involved in the decisions that are made regarding their care. They would prefer a personal, private physician as opposed to a revolving door of faces they will never see a second time. They rely strongly on family and friends to advise them on their choice of provider. They expect clean, well-maintained facilities, efficient systems and courteous personnel. In other respects, the conclusions are not

    Combustion of fossil fuels is likely to continue for the near future due to the growing trends in energy consumption worldwide. The increase in efficiency and the reduction of pollutant emissions from combustion devices are pivotal to achieving meaningful levels of carbon abatement as part of the ongoing climate change efforts. Computational fluid dynamics featuring adequate combustion models will play an increasingly important role in the design of more efficient and cleaner industrial burners, internal combustion engines, and combustors for stationary power generation and aircraft propulsion. Today, turbulent combustion modelling is hindered severely by the lack of data that are accurate and sufficiently complete to assess and remedy model deficiencies effectively. In particular, the formation of pollutants is a complex, nonlinear and multi-scale process characterized by the interaction of molecular and turbulent mixing with a multitude of chemical reactions with disparate time scales. The use of direct numerical simulation (DNS) featuring a state of the art description of the underlying chemistry and physical processes has contributed greatly to combustion model development in recent years. In this paper, the analysis of the intricate evolution of soot formation in turbulent flames demonstrates how DNS databases are used to illuminate relevant physico-chemical mechanisms and to identify modelling needs.

    The fabrication of polymer-nanoparticle composites is extremely important in the development of many functional materials. Identifying the precise composition of these materials is essential, especially in the design of surface catalysts, where the surface concentration of the active component determines the activity of the material. Antimicrobial materials which utilize nanoparticles are a particular focus of this technology. Recently swell encapsulation has emerged as a technique for inserting antimicrobial nanoparticles into a host polymer matrix. Swell encapsulation provides the advantage of localizing the incorporation to the external surfaces of materials, which act as the active sites of these materials. However, quantification of this nanoparticle uptake is challenging. Previous studies explore the link between antimicrobial activity and surface concentration of the active component, but this is not directly visualized. Here we show a reliable method to monitor the incorporation of nanoparticles into a polymer host matrix via swell encapsulation. We show that the surface concentration of CdSe/ZnS nanoparticles can be accurately visualized through cross-sectional fluorescence imaging. Using this method, we can quantify the uptake of nanoparticles via swell encapsulation and measure the surface concentration of encapsulated particles, which is key in optimizing the activity of functional materials.

    Conversion of light into an electrical current based on biohybrid systems mimicking natural photosynthesis is becoming increasingly popular. Photosystem I (PSI) is particularly useful in such photo-bioelectrochemical devices. Herein, we report on a novel biomimetic approach for an effective assembly of photosystem I with the electron transfer carrier cytochrome c (cyt c), deposited on a thiol-modified gold-surface. Atomic force microscopy and surface plasmon resonance measurements have been used for characterization of the assembly process. Photoelectrochemical experiments demonstrate a cyt c mediated generation of an enhanced unidirectional cathodic photocurrent. Here, cyt c can act as a template for the assembly of an oriented and dense layer of PSI and as wiring agent to direct the electrons from the electrode towards the photosynthetic reaction center of PSI. Furthermore, three-dimensional protein architectures have been formed via the layer-by-layer deposition technique resulting in a successive increase in photocurrent densities. An intermittent cyt c layer is essential for an efficient connection of PSI layers with the electrode and for an improvement of photocurrent densities. PMID:24957935

    2010-01-01

    In the post-Human Genome Project era, the debate on the concept of race/ethnicity and its implications for biomedical research are dependent on two critical issues: whether and how to classify individuals and whether biological factors play a role in health disparities. The advent of reliable estimates of genetic (or biogeographic) ancestry has provided this debate with a quantitative and more objective tool. The estimation of genetic ancestry allows investigators to control for population stratification in association studies and helps to detect biological causation behind population-specific differences in disease and drug response. New techniques such as admixture mapping can specifically detect population-specific risk alleles for a disease in admixed populations. However, researchers have to be mindful of the correlation between genetic ancestry and socioeconomic and environmental factors that could underlie these differences. More importantly, researchers must avoid the stigmatization of individuals based on perceived or real genetic risks. The latter point will become increasingly sensitive as several “for profit companies” are offering ancestry and genetic testing directly to consumers and the consequences of the spread of the services of these companies is still unforeseeable.

    Six runs on the bench unit were successfully completed this quarter. The runs covered twenty five different operating conditions and yield periods, and involved 336 hours of operation. In the bench unit, increased temperature of first stage operation (410{degree}C) and direct addition of the powdered solid sodium aluminate to the feed as first stage catalyst improved both coal and carbon monoxide conversion. To achieve 90%+ overall coal conversion, temperatures of 430{degree}C+ were required in the second stage. Oil yields (pentane soluble liquid product) in excess of 65 wt % based on MAF Black Thunder coal, were achieved both with iron oxide/dimethyl disulfide and ammonium molybdate/carbon disulfide second stage catalysts. C{sub l}-C{sub 3} hydrogen gas yields were modest, generally 7-8 wt % on MAF coal, and overall hydrogen consumption (including first stage shift hydrogen) was in the order of 7-8 wt % on MAF coal. The ammonium molybdate catalyst system appeared to give slightly higher oil yields and hydrogen consumption, as was expected, but the differences may not be significant.

    The Sockets Direct Protocol (SDP) is an industry standard to allow existing TCP/IP applications to be executed on high-speed networks such as InfiniBand (IB). Like many other high-speed networks, IB requires the receiver process to inform the network interface card (NIC), before the data arrives, about buffers in which incoming data has to be placed. To ensure that the receiver process is ready to receive data, the sender process typically performs flow-control on the data transmission. Existing designs of SDP flow-control are naive and do not take advantage of several interesting features provided by IB. Specifically, features such as RDMA are only used for performing zero-copy communication, although RDMA has more capabilities such as sender-side buffer management (where a sender process can manage SDP resources for the sender as well as the receiver). Similarly, IB also provides hardware flow-control capabilities that have not been studied in previous literature. In this paper, we utilize these capabilities to improve the SDP flow-control over IB using two designs: RDMA-based flow-control and NIC-assisted RDMA-based flow-control. We evaluate the designs using micro-benchmarks and real applications. Our evaluations reveal that these designs can improve the resource usage of SDP and consequently its performance by an order-of-magnitude in some cases. Moreover we can achieve 10-20% improvement in performance for various applications.

    This article has been developed for allied health professionals. These practitioners may face significant barriers to providing high-quality healthcare to people with intellectual disabilities, just because they lack awareness of policies and initiatives in health. There are fundamental issues to address within the context of healthcare provision that are of direct relevance to improving services for people with intellectual disabilities with regard to their empowerment and the facilitation of care. Emphasis is placed upon the need for equity in healthcare for all and the need to avoid the tendency of society to homogenise all individual people with intellectual disabilities into one group, for whom empowerment cannot become panacea in reality.

    Five Bench-Scale coal liquefaction runs were completed with Wyoming subbituminous coal in a two-stage process scheme. In this process scheme, LDAR, the lighter fraction of ash-free resid, was fed to the catalytic stage prior to its recycle to the thermal stage, whereas DAR, the heavy fraction of the deashed resid, was directly recycled to the thermal stage without any intermediate processing step. The results indicate that increasing coal space rate in the dissolver resulted in lower coal conversion and reduced distillate yield in this process configuration. The coal conversions decreased from 92 wt% to 89 wt% (MAF coal) and the distillate yield was reduced from 50 wt% to less than 40 wt% (MAF coal), as the coal space velocity increased. Attempts to duplicate the yields of Run 32, at comparable process conditions in Runs 37 and 38, were unsuccessful. Several process parameters were investigated but failed to show why the yields of Run 32 could not be duplicated. Valuable process related information was gained as a result of process parameter studies completed during these runs. At comparable process conditions, coal conversions were lower by about 3 to 4 relative percent and were only in the 87 wt% (MAF coal) range. Similarly, the distillate yield was about 40 wt% (MAF coal) which is about 10 wt% lower than observed in Run 32. Although no exact cause for these results could be determined, it appeared that the H/C atomic ratio of the solvent and possibly the flow pattern (plug-flow versus back-mixed) could have affected the coal conversion and quantity of distillate product produced. A significant decrease in coal conversion of 4 to 5 wt% was observed when the disposable catalyst (iron oxide) was removed from the reaction mixture and therefore substantiates the need for a disposable catalyst in the liquefaction of Wyoming subbituminous coal.

    Biomaterials are being used for the healthcare applications from ancient times. But subsequent evolution has made them more versatile and has increased their utility. Biomaterials have revolutionized the areas like bioengineering and tissue engineering for the development of novel strategies to combat life threatening diseases. Together with biomaterials, stem cell technology is also being used to improve the existing healthcare facilities. These concepts and technologies are being used for the treatment of different diseases like cardiac failure, fractures, deep skin injuries, etc. Introduction of nanomaterials on the other hand is becoming a big hope for a better and an affordable healthcare. Technological advancements are underway for the development of continuous monitoring and regulating glucose levels by the implantation of sensor chips. Lab-on-a-chip technology is expected to modernize the diagnostics and make it more easy and regulated. Other area which can improve the tomorrow’s healthcare is drug delivery. Micro-needles have the potential to overcome the limitations of conventional needles and are being studied for the delivery of drugs at different location in human body. There is a huge advancement in the area of scaffold fabrication which has improved the potentiality of tissue engineering. Most emerging scaffolds for tissue engineering are hydrogels and cryogels. Dynamic hydrogels have huge application in tissue engineering and drug delivery. Furthermore, cryogels being supermacroporous allow the attachment and proliferation of most of the mammalian cell types and have shown application in tissue engineering and bioseparation. With further developments we expect these technologies to hit the market in near future which can immensely improve the healthcare facilities. PMID:23628868

    Telemental health (TMH) has established a niche as a feasible, acceptable, and effective service model to improve the mental healthcare and outcomes for individuals who cannot access traditional mental health services. The Accountability Care Act has mandated reforms in the structure, functioning, and financing of primary care that provide an opportunity for TMH to move into the mainstream healthcare system. By partnering with the Integrated Behavioral Healthcare Model, TMH offers a spectrum of tools to unite primary care physicians and mental health specialist in a mind-body view of patients' healthcare needs and to activate patients in their own care. TMH tools include video-teleconferencing to telecommute mental health specialists to the primary care setting to collaborate with a team in caring for patients' mental healthcare needs and to provide direct services to patients who are not progressing optimally with this collaborative model. Asynchronous tools include online therapies that offer an efficient first step to treatment for selected disorders such as depression and anxiety. Patients activate themselves in their care through portals that provide access to their healthcare information and Web sites that offer on-demand information and communication with a healthcare team. These synchronous and asynchronous TMH tools may move the site of mental healthcare from the clinic to the home. The evolving role of social media in facilitating communication among patients or with their healthcare team deserves further consideration as a tool to activate patients and provide more personalized care.

    As antibiotic resistance increases and the rate of antibiotic development slows, it is becoming more urgent to develop novel approaches to prevent and mitigate serious bacterial and fungal infections. Healthcare-associated infections (HAIs), including those caused by Clostridium difficile, Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, carbapenem-resistant Enterobacteriaceae, and Candida species, are a major cause of morbidity, mortality, and healthcare costs. HAIs are also a key driver of antibiotic use. Vaccines directed toward these pathogens could help prevent a large number of HAIs and associated antibiotic use if administered to targeted populations. Despite numerous scientific and operational challenges, there are vaccine candidates in late-stage clinical development for C. difficile, S. aureus, and P. aeruginosa Basic, preclinical, and early clinical research to develop vaccines for other types of HAIs is also under way. In addition, other prophylactic immune interventions, such as monoclonal antibodies, for several of these pathogens are in advanced development. Here we describe the promise, challenges, and current pipeline of vaccines to prevent HAIs. PMID:27208045

    Arthur D. Little, Inc., together with its commercialization partner, Engelhard Corporation, and its university partner Tufts, investigated a single-step process for direct, catalytic reduction of sulfur dioxide from regenerable flue gas desulfurization processes to the more valuable elemental sulfur by-product. This development built on recently demonstrated SO{sub 2}-reduction catalyst performance at Tufts University on a DOE-sponsored program and is, in principle, applicable to processing of regenerator off-gases from all regenerable SO{sub 2}-control processes. In this program, laboratory-scale catalyst optimization work at Tufts was combined with supported catalyst formulation work at Engelhard, bench-scale supported catalyst testing at Arthur D. Little and market assessments, also by Arthur D. Little. Objectives included identification and performance evaluation of a catalyst which is robust and flexible with regard to choice of reducing gas. The catalyst formulation was improved significantly over the course of this work owing to the identification of a number of underlying phenomena that tended to reduce catalyst selectivity. The most promising catalysts discovered in the bench-scale tests at Tufts were transformed into monolith-supported catalysts at Engelhard. These catalyst samples were tested at larger scale at Arthur D. Little, where the laboratory-scale results were confirmed, namely that the catalysts do effectively reduce sulfur dioxide to elemental sulfur when operated under appropriate levels of conversion and in conditions that do not contain too much water or hydrogen. Ways to overcome those limitations were suggested by the laboratory results. Nonetheless, at the end of Phase I, the catalysts did not exhibit the very stringent levels of activity or selectivity that would have permitted ready scale-up to pilot or commercial operation. Therefore, we chose not to pursue Phase II of this work which would have included further bench-scale testing

Because APS beamlines are nearly fully built out, we have limited freedom to place LSSs in a symmetric fashion. Arbitrarily-placed LSSs will drastically reduce the symmetry of the optics and would typically be considered unworkable. We apply a recently-developed multi-objective direct optimization technique that relies on particle tracking to compute the dynamic aperture and Touschek lifetime. We show that this technique is able to tune sextupole strengths and select the working point in such a way as to recover the dynamic and momentum acceptances. We also show the results of experimental tests of lattices developed using these techniques.

    It is unknown whether hospital-based medical professionals in Spain educate patients about advance directives (ADs). The objective of this research was to determine the frequency of hospital-based physicians' and nurses' engagement in AD discussions in the hospital and which patient populations merit such efforts. A short question-and-answer-based survey of physicians and nurses taking care of inpatients was conducted at a university hospital in Madrid, Spain. In total, 283 surveys were collected from medical professionals, of whom 71 per cent were female, with an average age of thirty-four years. Eighty-four per cent had never educated patients about ADs because of lack of perceived responsibility, time, or general knowledge of ADs. Patient populations that warranted AD discussions included those with terminal illnesses (77 per cent), chronic diseases (61 per cent), and elderly patients (43 per cent). Regarding degree of AD understanding in medical professionals: 57 per cent of medical professionals claimed sufficient general knowledge of ADs, 19 per cent understood particulars regarding AD document creation, and 16 per cent were aware of AD regulatory policies. Engagement in AD discussions was considered important by 83 per cent of medical professionals, with 79 per cent interested in participating in such discussions themselves. The majority of hospital physicians and nurses do not educate their patients about ADs, despite acknowledging their importance. Patient populations of highest priority included those with terminal diseases or chronic illness or who are of advanced age. PMID:26797513

    This article presents a model of the healthcare value chain which consists of a schematic representation of the Brazilian healthcare system. The proposed model is adapted for the Brazilian reality and has the scope and flexibility for use in academic activities and analysis of the healthcare sector in Brazil. It places emphasis on three components: the main activities of the value chain, grouped in vertical and horizontal links; the mission of each link and the main value chain flows. The proposed model consists of six vertical and three horizontal links, amounting to nine. These are: knowledge development; supply of products and technologies; healthcare services; financial intermediation; healthcare financing; healthcare consumption; regulation; distribution of healthcare products; and complementary and support services. Four flows can be used to analyze the value chain: knowledge and innovation; products and services; financial; and information. PMID:23099762

  18. Addressing language barriers to healthcare in India.

    2013-01-01

    In spite of a growing recognition of the importance of doctor-patient communication, the issue of language barriers to healthcare has received very little attention in India. The Indian population speaks over 22 major languages with English used as the lingua franca for biomedicine. Large-scale internal migration has meant that health workers are encountering increasing instances of language discordance within clinical settings. Research done predominantly in the West has shown language discordance to significantly affect access to care, cause problems of comprehension and adherence, and decrease the satisfaction and quality of care. Addressing language barriers to healthcare in India requires a stronger political commitment to providing non-discriminatory health services, especially to vulnerable groups such as illiterate migrant workers. Research will have to address three broad areas: the ways in which language barriers affect health and healthcare, the efficacy of interventions to overcome language barriers, and the costs of language barriers and efforts to overcome them. There is a need to address such barriers in health worker education and clinical practice. Proven strategies such as hiring multilingual healthcare workers, providing language training to health providers, employing in situ translators or using telephone interpretation services will have to be evaluated for their appropriateness to the Indian context. Internet-based initiatives, the proliferation of mobile phones and recent advances in machine translation promise to contribute to the solution. PMID:24758452

    The Advanced Direct Liquefaction Concepts Program sponsored by the DOE Pittsburgh Energy Technology Center was initiated in 1991 with the objective of promoting the development of new and emerging technology that has the potential for reducing the cost of producing liquid fuels by direct coal liquefaction. The laboratory research program (Phase I) was completed in 1995 by UK/CAER, CONSOL, Sandia National Laboratories and LDP Associates. A three year extension was subsequently awarded in October 1995 to further develop several promising concepts derived from the laboratory program. During Phase II, four continuous bench scale runs will be conducted at Hydrocarbon Technologies, Inc. using a 2 kg/hr continuous bench scale unit located at their facility in Lawrenceville, NJ. The first run in this program (ALC-1), conducted between April 19 and May 14, 1996, consisted of five test conditions to evaluate the affect of coal cleaning and recycle solvent modification. A detailed discussion of this run is included in Section Two of this report. Results obtained during this reporting period for all participants in this program are summarized.

    Nunes, Rui; Brandão, Cristina; Rego, Guilhermina

    2011-12-01

    The lack of economic sustainability of most healthcare systems and a higher demand for quality and safety has contributed to the development of regulation as a decisive factor for modernisation, innovation and competitiveness in the health sector. The aim of this paper is to determine the importance of the principle of public accountability in healthcare regulation, stressing the fact that sunshine regulation-as a direct and transparent control over health activities-is vital for an effective regulatory activity, for an appropriate supervision of the different agents, to avoid quality shading problems and for healthy competition in this sector. Methodologically, the authors depart from Kieran Walshe's regulatory theory that foresees healthcare regulation as an instrument of performance improvement and they articulate this theory with the different regulatory strategies. The authors conclude that sunshine regulation takes on a special relevance as, by promoting publicity of the performance indicators, it contributes directly and indirectly to an overall improvement of the healthcare services, namely in countries were citizens are more critical with regard to the overall performance of the system. Indeed, sunshine regulation contributes to the achievement of high levels of transparency, which are fundamental to overcoming some of the market failures that are inevitable in the transformation of a vertical and integrated public system into a decentralised network where entrepreneurialism appears to be the predominant culture.

    Myanmar transitioned to a civilian government in March, 2011. Although the democratic process has accelerated since then, many problems in the field of healthcare still exist. Since there is a limited overview on the healthcare in Myanmar, this article briefly describes the current states surrounding health services in Myanmar. According to the Census 2014, the population in the Republic of the Union of Myanmar was 51,410,000. The crude birth rate in the previous one year was estimated to be 18.9 per 1,000, giving the annual population growth rate of 0.89% between 2003 and 2014. The Ministry of Health reorganized into six departments. National non-governmental organizations and community-based organizations support healthcare, as well as international non-governmental organizations. Since hospital statistics by the government cover only public facilities, the information on private facilities is limited. Although there were not enough medical doctors (61 per 100,000 population), the number of medical students was reduced from 2,400 to 1,200 in 2012 to ensure the quality of medical education. The information on causes of death in the general population could not be retrieved, but some data was available from hospital statistics. Although the improvement was marked, the figures did not reach the levels set by Millennium Development Goals 4 and 5. A trial prepaid health insurance system started in July 2015, to be followed by evaluation one year later. There are many international donors, including the Japan International Cooperation Agency, supporting health in Myanmar. With these efforts and support, a marked progress is expected in the field of healthcare. PMID:27303099

    The degradation of alachlor by direct ozonation and advanced oxidation process O(3)/H(2)O(2) was investigated in this study with focus on identification of degradation byproducts. The second-order reaction rate constant between ozone and alachlor was determined to be 2.5+/-0.1M(-1)s(-1) at pH 7.0 and 20 degrees C. Twelve and eight high-molecular-weight byproducts (with the benzene ring intact) from alachlor degradation were identified during direct ozonation and O(3)/H(2)O(2), respectively. The common degradation byproducts included N-(2,6-diethylphenyl)-methyleneamine, 8-ethyl-3,4-dihydro-quinoline, 8-ethyl-quinoline, 1-chloroacetyl-2-hydro-3-ketone-7-acetyl-indole, 2-chloro-2',6'-diacetyl-N-(methoxymethyl)acetanilide, 2-chloro-2'-acetyl-6'-ethyl-N-(methoxymethyl)-acetanilide, and two hydroxylated alachlor isomers. In direct ozonation, four more byproducts were also identified including 1-chloroacetyl-2,3-dihydro-7-ethyl-indole, 2-chloro-2',6'-ethyl-acetanilide, 2-chloro-2',6'-acetyl-acetanilide and 2-chloro-2'-ethyl-6'-acetyl-N-(methoxymethyl)-acetanilide. Degradation of alachlor by O(3) and O(3)/H(2)O(2) also led to the formation of low-molecular-weight byproducts including formic, acetic, propionic, monochloroacetic and oxalic acids as well as chloride ion (only detected in O(3)/H(2)O(2)). Nitrite and nitrate formation was negligible. Alachlor degradation occurred via oxidation of the arylethyl group, N-dealkylation, cyclization and cleavage of benzene ring. After O(3) or O(3)/H(2)O(2) treatment, the toxicity of alachlor solution examined by the Daphnia magna bioassay was slightly reduced. PMID:20022076

    Despite the fact that most American physicians, at least until around the 1970s, stood in the way of developing a universal healthcare system, most are generally not happy with the current state of healthcare – or its lack thereof – today. The primary reasons for this general unhappiness are that insurance companies and managed care have successfully conspired to remove much of the physician's autonomy (via imposed time constraints, burdensome paperwork, the time-consuming chore of having to defend going against stringent treatment algorithms that are often inappropriate for some patients) and the satisfaction of knowing their patients. Few physicians in managed care organizations (MCOs) are able to practice without constant and blindly algorithmic interference concerning the diagnostic tests and therapeutic interventions they order. As copayments have increased, they often find that patients, even though “covered,” cannot afford the therapy they deem necessary. While physicians expect to earn sufficient to pay back their not insignificant educational debts, provide their children with help through college, and assure retirements sufficient for themselves and their spouses, these should not be considered unreasonable expectations. Most physicians today do favor universal healthcare – to the point of having included such language in their various professional codes of ethics (which, perversely enough, bioethicists as a group have failed to do). Contrary to the claims of our colleagues, Altom and Churchill, physicians seem to be genuinely frustrated as to what else they can do to change the current inequitable system. PMID:17435646

    The mission of HL7 Inc. is to provide standards for the exchange, management and integration of data that supports clinical patient care and the management, delivery and evaluation of healthcare services. The scope of this work includes the specifications of flexible, cost-effective approaches, standards, guidelines, methodologies, and related services for interoperability between healthcare information systems. In the field of medical information technologies, HL7 provides the world's most advanced information standards. Versions 1 and 2 of the HL7 standard have on the one hand solved many issues, but on the other demonstrated the size and complexity of the health information sharing problem. As the solution, a complete new methodology has been adopted, which is being encompassed in version 3 recommendations. This approach standardizes the Reference Information Model (RIM), which is the source of all domain models and message structures. Message design is now defined in detail, enabling interoperability between loosely-coupled systems that are designed by different vendors and deployed in various environments. At the start of the Primary Healthcare Information System project, we have decided to go directly to HL7v3. Implementing the HL7v3 standard in healthcare applications represents a challenging task. By using standardized refinement and localization methods we were able to define information models for Croatian primary healthcare domain. The scope of our work includes clinical, financial and administrative data management, where in some cases we were compelled to introduce new HL7v3-compliant models. All of the HL7v3 transactions are digitally signed, using the W3C XML Digital Signature standard. PMID:15718621

  9. Advanced nursing practice and Newton's three laws of motion.

    PubMed

    Sturgeon, David

    This article considers the reasons for the development of advanced practice roles among nurses and other healthcare professions. It explores the implications of financial constraints, consumer preferences and the development of new healthcare services on the reorganization of professional boundaries. It makes use of Sir Isaac Newton's three laws of motion to demonstrate how professional development in nursing has taken place in response to a number of external influences and demands. It also considers the significance of skill mix for the nursing profession, in particular the development and likely expansion of the physician assistant role. The application of different professionals and grades within a healthcare team or organization is central to the Government's Agenda for Change proposals and nurses have successfully adopted a number of roles traditionally performed by doctors. Nurses have demonstrated that they are capable of providing high quality care and contributing directly to positive patient outcome. Advanced nursing roles should not only reflect the changing nature of healthcare work, they should also be actively engaged in reconstructing healthcare boundaries. PMID:18773586

    The citizens of many countries have long traveled to the United States and to the developed countries of Europe to seek the expertise and advanced technology available in leading medical centers. In the recent past, a trend known as medical tourism has emerged wherein citizens of highly developed countries choose to bypass care offered in their own communities and travel to less developed areas of the world to receive a wide variety of medical services. Medical tourism is becoming increasingly popular, and it is projected that as many as 750,000 Americans will seek offshore medical care in 2007. This phenomenon is driven by marketplace forces and occurs outside of the view and control of the organized healthcare system. Medical tourism presents important concerns and challenges as well as potential opportunities. This trend will have increasing impact on the healthcare landscape in industrialized and developing countries around the world. PMID:18311383

    2012-01-01

    Assisting or hastening death is a dilemma with many ethical as well as practical issues facing healthcare practitioners in most countries worldwide now. Various arguments for and against assisted dying have been made over time but the call from the public for the legalisation of euthanasia and assisted suicide has never been stronger. While some studies have documented the reluctance of medical and other healthcare professionals to be involved in the practice of assisted dying or euthanasia, there is still much open debate in the public domain. Those who have the most experience of palliative care are strongest in their opposition to hastening death. This paper explores salient practical and ethical considerations for healthcare practitioners associated with assisting death, including a focus on examining the concepts of autonomy for patients and healthcare practitioners. The role of the healthcare practitioner has clearly and undoubtedly changed over time with advances in healthcare practices but the duty of care has not changed. The dilemmas for healthcare practitioners thus who have competent patients requesting hastened death extends far beyond acting within a country’s laws as they go to the very heart of the relationship between the practitioner and patient.

    Fast Wave (FW) heating and electron cyclotron heating (ECH) are used in the DIII-D tokamak to study plasmas with low applied torque and dominant electron heating characteristic of burning plasmas. FW heating via direct electron damping has reached the 2.5 MW level in high performance ELMy H-mode plasmas. In Advanced Inductive (AI) plasmas, core FW heating was found to be comparable to that of ECH, consistent with the excellent first-pass absorption of FWs predicted by ray-tracing models at high electron beta. FW heating at the ∼2 MW level to ELMy H-mode discharges in the ITER Baseline Scenario (IBS) showed unexpectedly strong absorption of FW power by injected neutral beam (NB) ions, indicated by significant enhancement of the D-D neutron rate, while the intended absorption on core electrons appeared rather weak. The AI and IBS discharges are compared in an effort to identify the causes of the different response to FWs.

    The emerging Massively Parallel-Electron Beam Direct Write (MP-EBDW) is an attractive high resolution high throughput lithography technology. As previously shown, Chemically Amplified Resists (CARs) meet process/integration specifications in terms of dose-to-size, resolution, contrast, and energy latitude. However, they are still limited by their line width roughness. To overcome this issue, we tested an alternative advanced non-CAR and showed it brings a substantial gain in sensitivity compared to CAR. We also implemented and assessed in-line post-lithographic treatments for roughness mitigation. For outgassing-reduction purpose, a top-coat layer is added to the total process stack. A new generation top-coat was tested and showed improved printing performances compared to the previous product, especially avoiding dark erosion: SEM cross-section showed a straight pattern profile. A spin-coatable charge dissipation layer based on conductive polyaniline has also been tested for conductivity and lithographic performances, and compatibility experiments revealed that the underlying resist type has to be carefully chosen when using this product. Finally, the Process Of Reference (POR) trilayer stack defined for 5 kV multi-e-beam lithography was successfully etched with well opened and straight patterns, and no lithography-etch bias.

    Introduction Goal-directed echocardiography (GDE) is used to answer specific clinical questions which provide invaluable information to physicians managing a hemodynamically unstable patient. We studied perception and ability of housestaff previously trained in GDE to accurately diagnose common causes of cardiac arrest during simulated advanced cardiac life support (ACLS); we compared their results to those of expert echocardiographers. Methods Eleven pulmonary and critical care medicine fellows, seven emergency medicine residents, and five cardiologists board-certified in echocardiography were enrolled. Baseline ability to acquire four transthoracic echocardiography views was assessed and participants were exposed to six simulated cardiac arrests and were asked to perform a GDE during ACLS. Housestaff performance was compared to the performance of five expert echocardiographers. Results Average baseline and scenario views by housestaff were of good or excellent quality 89% and 83% of the time, respectively. Expert average baseline and scenario views were always of good or excellent quality. Housestaff and experts made the correct diagnosis in 68% and 77% of cases, respectively. On average, participants required 1.5 pulse checks to make the correct diagnosis. 94% of housestaff perceived this study as an accurate assessment of ability. Conclusions In an ACLS compliant manner, housestaff are capable of diagnosing management altering pathologies the majority of the time and they reach similar diagnostic conclusions in the same amount of time as expert echocardiographers in a simulated cardiac arrest scenario.

  17. Advanced byproduct recovery: Direct catalytic reduction of sulfur dioxide to elemental sulfur. Fourth quarterly technical progress report

    SciTech Connect

    1997-01-01

    The team of Arthur D. Little, Tufts University and Engelhard Corporation are conducting Phase 1 of a four and a half year, two-phase effort to develop and scale-up an advanced byproduct recovery technology that is a direct, single-stage, catalytic process for converting sulfur dioxide to elemental sulfur. This catalytic process reduces SO{sub 2} over a fluorite-type oxide (such as ceria and zirconia). The catalytic activity can be significantly promoted by active transition metals, such as copper. More than 95% elemental sulfur yield, corresponding to almost complete sulfur dioxide conversion, was obtained over a Cu-Ce-O oxide catalyst as part of an on-going DOE-sponsored, University Coal Research Program. This type of mixed metal oxide catalyst has stable activity, high selectivity for sulfur production, and is resistant to water and carbon dioxide poisoning. Tests with CO and CH{sub 4} reducing gases indicate that the catalyst has the potential for flexibility with regard to the composition of the reducing gas, making it attractive for utility use. The performance of the catalyst is consistently good over a range of SO{sub 2} inlet concentration (0.1 to 10%) indicating its flexibility in treating SO{sub 2} tail gases as well as high concentration streams.

    2013-01-01

    Service Oriented Architecture (SOA) is increasingly adopted by many sectors, including healthcare. Due to the nature of healthcare systems there is a need to increase SOA adoption success rates as the non integrated nature of healthcare systems is responsible for medical errors that cause the loss of tens of thousands patients per year. Following our previous research [1] we propose that SOA governance is a critical success factor for SOA success in healthcare. Literature reports multiple SOA governance models that have limitations and they are confusing. In addition to this, there is a lack of healthcare specific SOA governance models. This highlights a literature void and thus the purpose of this paper is to proposed a healthcare specific SOA governance framework. PMID:23823423

    Data from private insurance companies make it possible to analyse how healthcare spending is distributed across individuals, how it depends on the age of the people and how it changes over time. Within age groups, healthcare spending is less concentrated if recipients are older. Over the analysed period of time, a considerable levelling of expenses takes place. These findings lead to the conclusion that the ageing population will result in a greater and more evenly spread utilisation of healthcare facilities. PMID:18405231

  1. PPEPR for Enterprise Healthcare Integration

    NASA Astrophysics Data System (ADS)

    Fox, Ronan; Sahay, Ratnesh; Hauswirth, Manfred

    PPEPR is software to connect healthcare enterprises. Healthcare is a complex domain and any integration system that connects healthcare enterprise applications must facilitate heterogeneous healthcare systems at all levels - data, services, processes, healthcare vendors, standards, legacy systems, and new information systems, all of which must interoperate to provide healthcare services. The lack of interoperability within healthcare standards (e.g. HL7) adds complexity to the interoperability initiatives. HL7’s user base has been growing since the early 2000s. There are many interoperability issues between the widely adopted HL7 v2 and its successor, HL7 v3, in terms of consistency, data/message modeling, precision, and useability. We have proposed an integration platform called PPEPR: (Plug and Play Electronic Patient Records) which is based on a semantic Service-oriented Architecture (sSOA). PPEPR connects HL7 (v2 & v3) compliant healthcare enterprises. Our main goal is to provide seamless integration between healthcare enterprises without imposing any constraint on existing or proposed EPRs.

    Objective To describe the development of an innovative, multimedia decision aid for advance care planning. Background Advance care planning is an important way for people to articulate their wishes for medical care when they are not able to speak for themselves. Living wills and other types of advance directives are the most commonly used tools for advance care planning, but have been criticized for being vague, difficult to interpret, and inconsistent with individuals’ core beliefs and values. Results We developed a multimedia, computer-based decision aid for advance care planning (‘Making Your Wishes Known: Planning Your Medical Future’) to overcome many of the limitations of standard advance directive forms. This computer program guides individuals through the process of advance care planning, and unlike standard advance directives, provides tailored education, values clarification exercises, and a decision-making tool that translates an individual’s values and preferences into a specific medical plan that can be implemented by a health-care team. Pilot testing with 50 adult volunteers recruited from an outpatient primary care clinic showed high levels of satisfaction with the program. Further pilot testing with 34 cancer patients indicated that the program was perceived to be highly accurate at representing patients’ wishes. Conclusions This paper describes the development of an innovative decision aid for advance care planning that was designed to overcome common problems with standard advance directives. Preliminary testing suggests that it is acceptable to users and is accurate. PMID:18823445

    The relationship between literacy and health outcomes are well documented in adult medicine, yet specific causal pathways are not entirely clear. Despite an incomplete understanding of the problem, numerous interventions have already been implemented with variable success. Many of the earlier strategies assumed the problem to originate from reading difficulties only. Given the timely need for more effective interventions, it is of increasing importance to reconsider the meaning of health literacy in order to advance our conceptual understanding of the problem and how best to respond. One potentially effective approach might involve recognizing the known associations between a larger set of cognitive and psychosocial abilities with functional literacy skills. We review the current health literacy definition and literature and draw upon relevant research from the fields of education, cognitive science, and psychology. In this framework, a research agenda is proposed that considers an individual's health learning capacity, referring to the broad constellation of cognitive and psychosocial skills patients or family members must draw upon to effectively promote, protect, and manage their own or a child's health. This new, related concept will ideally lead to more effective ways of thinking about health literacy interventions, including the design of health education materials, instructional strategies, and the delivery of healthcare services to support patients and families across the lifespan.

    Nurses' knowledge regarding advance directives may affect their administration and completion in end-of-life care. Confidence among nurses is a barrier to the provision of quality end-of-life care. This study investigated nurses' knowledge of advance directives and perceived confidence in end-of-life care, in Hong Kong, Ireland, Israel, Italy and the USA using a cross-sectional descriptive design (n = 1089). In all countries, older nurses and those who had more professional experience felt more confident managing patients' symptoms at end-of-life and more comfortable stopping preventive medications at end-of-life. Nurses in the USA reported that they have more knowledge and experience of advance directives compared with other countries. In addition, they reported the highest levels of confidence and comfort in dealing with end-of-life care. Although legislation for advance directives does not yet exist in Ireland, nurses reported high levels of confidence in end-of-life care. PMID:26823112

    User experience design that reflects real-world application and aims to support suitable service solutions has arisen as one of the current issues in the medical informatics research domain. The Smart Bedside Station (SBS) is a screen that is installed on the bedside for the personal use and provides a variety of convenient services for the patients. Recently, bedside terminal systems have been increasingly adopted in hospitals due to the rapid growth of advanced technology in healthcare at the point of care. We designed user experience (UX) research to derive users' unmet needs and major functions that are frequently used in the field. To develop the SBS service, a service design methodology, the Double Diamond Design Process Model, was undertaken. The problems or directions of the complex clinical workflow of the hospital, the requirements of stakeholders, and environmental factors were identified through the study. The SBS system services provided to patients were linked to the hospital's main services or to related electronic medical record (EMR) data. Seven key services were derived from the results of the study. The primary services were as follows: Bedside Check In and Out, Bedside Room Service, Bedside Scheduler, Ready for Rounds, My Medical Chart, Featured Healthcare Content, and Bedside Community. This research developed a patient-centered SBS system with improved UX using service design methodology applied to complex and technical medical services, providing insights to improve the current healthcare system.

    This presentation briefly reviews the SiC/SiC major environmental and environment-fatigue degradations encountered in simulated turbine combustion environments, and thus NASA environmental barrier coating system evolution for protecting the SiC/SiC Ceramic Matrix Composites for meeting the engine performance requirements. The presentation will review several generations of NASA EBC materials systems, EBC-CMC component system technologies for SiC/SiC ceramic matrix composite combustors and turbine airfoils, highlighting the temperature capability and durability improvements in simulated engine high heat flux, high pressure, high velocity, and with mechanical creep and fatigue loading conditions. This paper will also focus on the performance requirements and design considerations of environmental barrier coatings for next generation turbine engine applications. The current development emphasis is placed on advanced NASA candidate environmental barrier coating systems for SiC/SiC CMCs, their performance benefits and design limitations in long-term operation and combustion environments. The efforts have been also directed to developing prime-reliant, self-healing 2700F EBC bond coat; and high stability, lower thermal conductivity, and durable EBC top coats. Major technical barriers in developing environmental barrier coating systems, the coating integrations with next generation CMCs having the improved environmental stability, erosion-impact resistance, and long-term fatigue-environment system durability performance will be described. The research and development opportunities for turbine engine environmental barrier coating systems by utilizing improved compositions, state-of-the-art processing methods, and simulated environment testing and durability modeling will be briefly discussed.

  9. Advanced byproduct recovery: Direct catalytic reduction of sulfur dioxide to elemental sulfur. Quarterly report, April 1--June 30, 1997

    The team of Arthur D. Little, Tufts University and Engelhard Corporation are conducting Phase 1 of a four and a half year, two-phase effort to develop and scale-up an advanced byproduct recovery technology that is a direct, single-stage, catalytic process for converting sulfur dioxide to elemental sulfur. This catalytic process reduces SO{sub 2} over a fluorite-type oxide (such as ceria and zirconia). The catalytic activity can be significantly promoted by active transition metals, such as copper. More than 95% elemental sulfur yield, corresponding to almost complete sulfur dioxide conversion, was obtained over a Cu-Ce-O oxide catalyst as part of an on-going DOE-sponsored, University Coal Research Program. This type of mixed metal oxide catalyst has stable activity, high selectivity for sulfur production, and is resistant to water and carbon dioxide poisoning. Tests with CO and CH{sub 4} reducing gases indicate that the catalyst has the potential for flexibility with regard to the composition of the reducing gas, making it attractive for utility use. The performance of the catalyst is consistently good over a range of SO{sub 2} inlet concentration (0.1 to 10%) indicating its flexibility in treating SO{sub 2} tail gases as well as high concentration streams. The principal objective of the Phase 1 program is to identify and evaluate the performance of a catalyst which is robust and flexible with regard to choice of reducing gas. In order to achieve this goal, the authors have planned a structured program including: Market/process/cost/evaluation; Lab-scale catalyst preparation/optimization studies; Lab-scale, bulk/supported catalyst kinetic studies; Bench-scale catalyst/process studies; and Utility review. Progress is reported from all three organizations.

    In regulatory assessments, there is a need for reliable estimates of the impacts of precursor emissions from individual sources on secondary PM2.5 (particulate matter with aerodynamic diameter less than 2.5 microns) and ozone. Three potential methods for estimating these impacts using Eulerian grid photochemical models are the brute-force (B-F) method, the decoupled direct method (DDM), and advanced plume treatment (APT). Here, we systematically inter-compare and assess the B-F, DDM, and APT approaches using hypothetical sources in a consistent modeling platform for a wide range of source conditions (i.e., emissions amount and composition, location within two California air basins, and stack parameters). The impacts of NOx and VOC sources on ozone and SO2 sources on PM2.5 sulfate calculated by these methods are in general agreement. The agreement is evident in the similar magnitudes, spatial patterns, and strong correlations among the impacts. This result, along with previous model evaluations based on similar Eulerian grid modeling, builds confidence in the reliability of the impact estimates. Disagreement among methods is evident in calculations of PM2.5 nitrate impacts associated with NH3 and NOx sources. Numerical instabilities in DDM sensitivity calculations compromise the nitrate impact estimates from that approach. The B-F and APT methods, which use brute-force differencing to identify impacts, are affected by numerical artifacts to a lesser degree than (H)DDM, with the artifacts being more prominent for APT than B-F. Overall, our results indicate that the (H)DDM, B-F, and APT approaches are viable for use in estimating single-source impacts for ozone and secondary PM2.5 sulfate, while the B-F method appears to be the most reliable for estimating nitrate impacts. There is a need for additional field study measurements to better constrain model estimates of single-source secondary impacts.

  11. Advanced product recovery: Direct catalytic reduction of sulfur dioxide to elemental sulfur. Third quarterly technical progress report

    1996-07-01

    More than 170 wet scrubber systems applied to 72,000 MW of US, coal-fired, utility boilers are in operation or under construction. In these systems, the sulfur dioxide removed form the boiler flue gas is permanently bound to a sorbent material, such as lime or limestone. The sulfated sorbent must be disposed of as a waste product or, in some cases, sold as a byproduct (e.g. gypsum). The use of regenerable sorbent technologies has the potential to reduce or eliminate solid waste production, transportation and disposal. Arthur D. Little, Inc., together with its industry and commercialization advisor, Engelhard Corporation, and its university partner, Tufts, plans to develop and scale-up an advanced, byproduct recovery technology that is a direct, catalytic process for reducing sulfur dioxide to elemental sulfur. The principal objective of the Phase 1 program is to identify and evaluate the performance of a catalyst which is robust and flexible with regard to choice of reducing gas. In order to achieve this goal, they have planned a structured program including: market/process/cost/evaluation; lab-scale catalyst preparation/optimization studies; lab-scale, bulk/supported catalyst kinetic studies; bench-scale catalyst/process studies; and utility review.

    Alarmingly high rates of disease-related malnutrition have persisted in hospitals of both emerging and industrialized nations over the past 2 decades, despite marked advances in medical care over this same interval. In Latin American hospitals, the numbers are particularly striking; disease-related malnutrition has been reported in nearly 50% of adult patients in Argentina, Brazil, Chile, Costa Rica, Cuba, Dominican Republic, Ecuador, Mexico, Panama, Paraguay, Peru, Puerto Rico, Venezuela, and Uruguay. The tolls of disease-related malnutrition are high in both human and financial terms—increased infectious complications, higher incidence of pressure ulcers, longer hospital stays, more frequent readmissions, greater costs of care, and increased risk of death. In an effort to draw attention to malnutrition in Latin American healthcare, a feedM.E. Latin American Study Group was formed to extend the reach and support the educational efforts of the feedM.E. Global Study Group. In this article, the feedM.E. Latin American Study Group shows that malnutrition incurs excessive costs to the healthcare systems, and the study group also presents evidence of how appropriate nutrition care can improve patients’ clinical outcomes and lower healthcare costs. To achieve the benefits of nutrition for health throughout Latin America, the article presents feedM.E.’s simple and effective Nutrition Care Pathway in English and Spanish as a way to facilitate its use.

    The central attributes of primary care are: first contact (accessibility), longitudinality (person- focused preventive and curative care overtime), patient-oriented comprehensiveness and coordination (including navigation towards secondary and tertiary care). Besides taking care of the needs of the individuals, primary health care teams are also looking at the community, especially when addressing social determinants of health. The rationale for the benefits for primary care for health has been found in: 1) greater access to needed services; 2) better quality of care; 3) a greater focus on prevention; 4) early management of health problems; 5) organizing and delivering high quality care for chronic non-communicable diseases. This paper describes the role of primary healthcare centres in strengthening community primary services and in reducing health inequalities.

    Healthcare institutions and providers are in complexity. Networks of interconnections from relationships and technology create conditions in which interdependencies and non-linear dynamics lead to surprising, unpredictable outcomes. Previous effective approaches to leadership, focusing on top-down bureaucratic methods, are no longer effective. Leading in complexity requires leaders to accept the complexity, create an adaptive space in which innovation and creativity can flourish and then integrate the successful practices that emerge into the formal organizational structure. Several methods for doing adaptive space work will be discussed. Readers will be able to contrast traditional leadership approaches with leading in complexity. They will learn new behaviours that are required of complexity leaders, along with challenges they will face, often from other leaders within the organization. PMID:25815410

    Investments in the extension of health insurance coverage, the strengthening of public health services, as well as primary care and better hospitals, highlights the emerging role of healthcare as part of China’s new growth regime, based on an expansion of services, and redistributive policies. Such investments, apart from their central role in terms of relief for low-income people, serve to rebalance the Chinese economy away from export-led growth toward the domestic market, particularly in megacity-regions as Shanghai and the Pearl River Delta, which confront the challenge of integrating migrant workers. Based on the paper by Gusmano and colleagues, one would expect improvements in population health for permanent residents of China’s cities. The challenge ahead, however, is how to address the growth of inequalities in income, wealth and the social wage. PMID:25774379

    This paper examines the accountability structures within primary healthcare (PHC) in Ontario; in particular, who is accountable for what and to whom, and the policy tools being used. Ontario has implemented a series of incremental reforms, using expenditure policy instruments, enforced through contractual agreements to provide a defined set of publicly financed services that are privately delivered, most often by family physicians. The findings indicate that reporting, funding, evaluation and governance accountability requirements vary across service provider models. Accountability to the funder and patients is most common. Agreements, incentives and compensation tools have been used but may be insufficient to ensure parties are being held responsible for their activities related to stated goals. Clear definitions of various governance structures, a cohesive approach to monitoring critical performance indicators and associated improvement strategies are important elements in operationalizing accountability and determining whether goals are being met.

    In France, the European health card was created in June 2004 to increase the quality of healthcare granted to european citizen anywhere in europe and to facilitate the reimbursement of the healthcare costs. The patient identifier included in this card is essentially based on the healthcare insurance number of the patient and does not allow any linkage with his (her) previous health care data if he (she) is affiliated to another national healthcare insurance system when working for a long duration outside France. The purpose of this paper is to present the concept of a personal identifier based on familial components which has been validated by the French authority for personal data protection in the framework of a genetic study. Results issued from the Burgundy perinatal network demonstrate the interest and the faisability of adding a maternal component to the individual component of the new-born to allow Mother/new-born healthcare data linkage after anonymization. The advantage of adding a familial component to the healthcare insurance number is debated. This proposal will permit to link the data of a patient even when residing outside his country in Europe. It will also contribute to establish european public health statistics by matching healthcare data of the patients' records with other administrative data (mortality, social information ..) after anonymisation of these data in accordance with the European directive on data protection.

    Emerging new technologies in healthcare has proven great promises for managing patient care. In recent years, the evolution of Information and Communication Technologies pushes many research studies to think about treatment plan adaptation in this area. The main goal is to accelerate the decision making by dynamically generating new treatment due to unexpected situations. This paper portrays the treatment adaptation from a new perspective inspired from the human nervous system named autonomic computing. Thus, the selected potential studies are classified according to the maturity levels of this paradigm. To guarantee optimal and accurate treatment adaptation, challenges related to medical knowledge and data are identified and future directions to be explored in healthcare systems are discussed.

    Assisting or hastening death is a dilemma with many ethical as well as practical issues facing healthcare practitioners in many countries worldwide now. Various arguments for and against assisted dying have been made over time but the call from the public for legalisation of euthanasia or assisted suicide has never been stronger. While many studies have documented the reluctance of medical and other health professionals to be involved in the practice of assisted dying or euthanasia, there is still much open debate in the public domain. Those who have the most experience of palliative care are strongest in their opposition to assisted death or euthanasia. This paper explores salient practical and ethical considerations for healthcare practitioners associated with assisted death, with a focus on examining the concepts of autonomy for patients and healthcare practitioners. The role of the healthcare practitioner has clearly and undoubtedly changed over time with advances in healthcare practices but the duty of care has not changed. The dilemmas for healthcare practitioners thus who have competent patients requesting hastened death extends far beyond acting within a country's laws as they go to the very heart of the relationship between the practitioner and patient.

    Healthcare facilities are increasingly utilizing pictograms rather than text signs to help direct people. The purpose of this study was to analyze a wide variety of standardized healthcare pictograms and the effects of color contrasts and complexity for participants with both normal and impaired vision. Fifty (25 males, 25 females) participants completed a signage recognition questionnaire and identified pictograms while wearing vision simulators to represent specific visual impairment. The study showed that certain color contrasts, complexities and orientations can help or hinder comprehension of signage for people with and without visual impairment. High contrast signage with consistent pictograms involving human figures (not too detailed or too abstract) is most identifiable. Standardization of healthcare signage is recommended to speed up and aid the cognitive thought process in detecting signage and determining meaning. These fundamental signage principles are critical in producing an efficient, universal wayfinding system for healthcare facilities. PMID:21281930

    Confidential data hemorrhaging from health-care providers pose financial risks to firms and medical risks to patients. We examine the consequences of data hemorrhages including privacy violations, medical fraud, financial identity theft, and medical identity theft. We also examine the types and sources of data hemorrhages, focusing on inadvertent disclosures. Through an analysis of leaked files, we examine data hemorrhages stemming from inadvertent disclosures on internet-based file sharing networks. We characterize the security risk for a group of health-care organizations using a direct analysis of leaked files. These files contained highly sensitive medical and personal information that could be maliciously exploited by criminals seeking to commit medical and financial identity theft. We also present evidence of the threat by examining user-issued searches. Our analysis demonstrates both the substantial threat and vulnerability for the health-care sector and the unique complexity exhibited by the US health-care system.

    Laboratory services in healthcare delivery systems play a vital role in inpatient care. Studies have shown that laboratory data affects approximately 65% of the most critical decisions on admission, discharge, and medication. Laboratory testing accounts for approximately 10% of hospital billing. Reducing laboratory costs and improving laboratory performance would contribute to reducing total healthcare cost, which is one of the major goals for the U.S. healthcare delivery system. The objective of this paper is to review and analyze the diverse research approaches applied to improve the performance of hospital laboratories in large healthcare delivery systems. The approaches reviewed include: lean, quality control, automation, and simulation modeling. In the conclusion, future research directions are presented, which include additional methods to be investigated to further improve the performance of hospital laboratories. PMID:26185930

    Disasters either natural or man-made are inevitable, and therefore disaster management has always been an important function of government. Since during a disaster healthcare is often adversely affected, a lot of effort has been made in terms of researching effective responses and ways of improving the quality of delivered care to direct casualties and the rest of the community. In this regard, information technology plays an important role to help healthcare systems achieve this goal. One of these technologies that has become popular recently is Radio-Frequency Identification (RFID). This paper explores the relationship between emergency management and disaster healthcare and examines the role of RFID. It is suggested that RFID will become an integral part of disaster healthcare and a means of improving response performance. PMID:26262309

    Challenge has the potential to create opportunities for innovation. This applies to new developments aimed at enhancing existing systems of healthcare delivery. The development of the neonatal nurse practitioner's role in the United States is undoubtedly 1 such example of an innovation that was made in response to the challenge in neonatal healthcare delivery. This challenge and concomitant change was generated by a significant increase in neonatal patient needs, survival of smaller and sicker neonates, a rising acuity level, and the accompanying need to elevate the standard of healthcare for neonates. Nursing has faced such challenges more than once and been called upon to change the scope of practice not only in the United States but also globally. Japanese nursing is at a new historic moment since the end of World War II. There is an increased interest in expanding the role of nursing in collaboration with physicians to meet the complex needs of a growing neonatal intensive care population. However, for a nation where traditionally physician-led medicine was believed to maintain patient safety, nursing role advancement is met with significant opposition. This article will first describe the differences between neonatal intensive care unit workforce in Japan and in the United States and then introduce recent neonatal healthcare issues and the nation's response including an exploration of the neonatal nurse practitioner's (NNP's) role. Various barriers against nurse practitioner's role development are explained to better describe the context of NNP.

The amount of healthcare waste in these countries is continuously increasing as a result of the expansion of healthcare systems and services. In the past, healthcare waste, if it was treated at all, was mainly incinerated. In the last decade more comprehensive waste management systems were developed for Southeast Asian countries and implementation started. This also included the establishment of alternative healthcare waste treatment systems. The developments in the lower-middle-income countries are of special interest, as major investments are planned. Based upon sample projects, a short overview of the current development trends in the healthcare waste sector in Laos, Indonesia and Vietnam is provided. The projects presented include: (i) Lao Peoples Democratic Republic (development of the national environmental health training system to support the introduction of environmental health standards and improvement of healthcare waste treatment in seven main hospitals by introducing steam-based treatment technologies); (ii) Indonesia (development of a provincial-level healthcare waste-management strategy for Province Nanggroe Aceh Darussalam (NAD) and introduction of an advanced waste treatment system in a tertiary level hospital in Makassar); and (iii) Vietnam (development of a healthcare waste strategy for five provinces in Vietnam and a World Bank-financed project on healthcare waste in Vietnam).

    This review based on the Wickham lecture given by AC at the 2009 SMIT meeting in Sinaia outlines the progress made in nano-technology for healthcare. It describes in brief the nature of nano-materials and their unique properties which accounts for the significant research both in scientific institutions and industry for translation into new therapies embodied in the emerging field of nano-medicine. It stresses that the potential of nano-medicine to make significant inroads for more effective therapies both for life-threatening and life-disabling disorders will only be achieved by high-quality life science research. The first generation of passive nano-diagnostics based on nanoparticle contrast agents for magnetic resonance imaging is well established in clinical practice and new such contrast agents are undergoing early clinical evaluation. Likewise active (second generation) nano-therapies, exemplified by targeted control drug release systems are undergoing early clinical evaluation. The situation concerning other nano-materials such as carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs) is less advanced although considerable progress has been made on their coating for aqueous dispersion and functionalisation to enable carriage of drugs, genes and fluorescent markers. The main problem related to the clinical use of these nanotubes is that there is no consent among scientists on the fate of such nano-materials following injection or implantation in humans. Provided carbon nanotubes are manufactured to certain medical criteria (length around 1 mum, purity of 97-99% and low Fe content) they exhibit no cytotoxicity on cell cultures and demonstrate full bio-compatibility on in vivo animal studies. The results of recent experimental studies have demonstrated the potential of technologies based on CNTs for low voltage wireless electro-chemotherapy of tumours and for electro-stimulation therapies for cardiac, neurodegenerative and skeletal and visceral muscle

    Healthcare associated pneumonia (HCAP) is a different entity from community-acquired pneumonia and nosocomial pneumonia. There exist several risk factors that lead to it. Different features, severity and pathogens are described and there is controversy about the initial empirical treatment. The aim of this work was to analyze the etiology, clinical characteristics and evolution of the HCAP. It is a prospective and observational study that includes 60 patients; 32 had previous hospitalization during the last 90 days, 9 were under hemodialysis, 12 residents in nursing homes and 7 received outpatient intravenous therapy. The mean age was 63 years and the severity index was high. The most frequent comorbidities were cardiac. The radiological compromise was more than one lobe in 42% of cases and 18% had pleural effusion. Germ isolation was obtained in 30% of patients where the most isolated germ was Streptococcus pneumoniae (9 cases). There was only one case of multidrug-resistance. The mean length hospital stay was 11 days, six patients had complications and mortality was 5%. Complications but not mortality were significantly higher in the group of patients on hemodialysis (p value = 0.011 and 0.056 respectively). The antibiotic-resistance found do not justify a change in the antibiotic treatment commonly used for community acquired pneumonia. PMID:24561835

    If the "old economy" preached standardization of products/services in order to reduce costs, the "new economy" is based on the recognition of the needs and the management of information. It is aimed at providing better and more usable services. One scenario is a national health service with regional management but based on competition between hospitals/companies.This led to a different handling of the user/patient, which has become the center of the health system: marketing seeks to retain the patient, trying to push a client-patient to not change their healthcare service provider. In costs terms, it is more economical to retain a customer rather than acquire a new one: a satisfied customer is also the best sounding board for each company. Customer equity is the management of relations with patients which can result in a greater customer value: it is possible to recognize an equity of the value, of the brand and of the report. Loyalty uses various marketing activities (basic, responsive, responsible, proactive and collaborative): each hospital/company chooses different actions depending on how many resources it plans to invest in loyalty.

    2005-11-01

    The healthcare professions have never been static in terms of their own disciplinary boundaries, nor in their role or status in society. Healthcare provision has been defined by changing societal expectations and beliefs, new ways of perceiving health and illness, the introduction of a range of technologies and, more recently, the formal recognition of particular groups through the introduction of education and regulation. It has also been shaped by both inter-professional and profession-state relationships forged over time. A number of factors have converged that place new pressures on workforce boundaries, including an unmet demand for some healthcare services; neo-liberal management philosophies and a greater emphasis on consumer preferences than professional-led services. To date, however, there has been little analysis of the evolution of the workforce as a whole. The discussion of workforce change that has taken place has largely been from the perspective of individual disciplines. Yet the dynamic boundaries of each discipline mean that there is an interrelationship between the components of the workforce that cannot be ignored. The purpose of this paper is to describe four directions in which the existing workforce can change: diversification; specialisation and vertical and horizontal substitution, and to discuss the implications of these changes for the workforce.

    The importance of the process point of view is not restricted to a specific enterprise sector. In the field of health, as a result of the nature of the service offered, health institutions' processes are also the basis for decision making which is focused on achieving their objective of providing quality medical assistance. In this chapter the application of business process modelling - using the Business Process Modelling Notation (BPMN) standard is described. Main challenges of business process modelling in healthcare are the definition of healthcare processes, the multi-disciplinary nature of healthcare, the flexibility and variability of the activities involved in health care processes, the need of interoperability between multiple information systems, and the continuous updating of scientific knowledge in healthcare.

    At the 2011 American College of Medical Informatics (ACMI) Winter Symposium we studied the overlap between health IT and economics and what leading healthcare delivery organizations are achieving today using IT that might offer paths for the nation to follow for using health IT in healthcare reform. We recognized that health IT by itself can improve health value, but its main contribution to health value may be that it can make possible new care delivery models to achieve much larger value. Health IT is a critically important enabler to fundamental healthcare system changes that may be a way out of our current, severe problem of rising costs and national deficit. We review the current state of healthcare costs, federal health IT stimulus programs, and experiences of several leading organizations, and offer a model for how health IT fits into our health economic future.

  1. Designing the future of healthcare.

    PubMed

    Fidsa, Gianfranco Zaccai

    2009-01-01

    This paper describes the application of a holistic design process to a variety of problems plaguing current healthcare systems. A design process for addressing complex, multifaceted problems is contrasted with the piecemeal application of technological solutions to specific medical or administrative problems. The goal of this design process is the ideal customer experience, specifically the ideal experience for patients, healthcare providers, and caregivers within a healthcare system. Holistic design is shown to be less expensive and wasteful in the long run because it avoids solving one problem within a complex system at the cost of creating other problems within that system. The article applies this approach to the maintenance of good health throughout life; to the creation of an ideal experience when a person does need medical care; to the maintenance of personal independence as one ages; and to the enjoyment of a comfortable and dignified death. Virginia Mason Medical Center is discussed as an example of a healthcare institution attempting to create ideal patient and caregiver experiences, in this case by applying the principles of the Toyota Production System ("lean manufacturing") to healthcare. The article concludes that healthcare is inherently dedicated to an ideal, that science and technology have brought it closer to that ideal, and that design can bring it closer still. PMID:19745471

    Purpose - The purpose of this study is to evaluate how LEAN thinking is used as a management and development tool in the Finnish public healthcare system and what kind of outcomes have been achieved or expected by using it. The main focus is in managing and developing patient and treatment processes. Design/methodology/approach - A mixed-method approach incorporating the Webropol survey was used. Findings - LEAN is quite a new concept in Finnish public healthcare. It is mainly used as a development tool to seek financial savings and to improve the efficiency of patient processes, but has not yet been deeply implemented. However, the experiences from LEAN initiatives have been positive, and the methodology is already quite well-known. It can be concluded that, because of positive experiences from LEAN, the environment in Finnish healthcare is ready for the deeper implementation of LEAN. Originality/value - This paper evaluates the usage of LEAN thinking for the first time in the public healthcare system of Finland as a development tool and a management system. It highlights the implementation and achieved results of LEAN thinking when used in the healthcare environment. It also highlights the expectations for LEAN thinking in Finnish public healthcare.

    Diagnosing and treating young patients with cancer can be stressful for health professionals; however, when the prognosis is poor and the patient has dependent children, even experienced clinicians can feel distressed and helpless. Parents with advanced cancer commonly express anxiety about the impact of the disease on their children, yet health professionals often feel unable to respond constructively because of lack of training, or concern that discussion about such difficult issues will compound parental distress. In response to this problem, an educational manual has been devised to assist oncology staff to better understand the emotional impact of parental advanced cancer, encompassing information about specific reactions of children, including strategies to help children and families cope. This paper describes the development and content of the resource which provides clinically relevant information and evidence-based recommendations to guide supportive care. The manual differs from the more traditional didactic resources in that it examines the very personal impact for professionals working with parents with advanced disease, encouraging reflection and engages the reader in clinical exercises which encourage active learning and application of knowledge into authentic clinical contexts. Although the manual is designed primarily for nurses, it is clear that much of the information is relevant for all health professionals involved in the care of parents with advanced cancer.

Many of the key provisions regarding coverage and financing will unfold during the period of now through 2014. The primary strategies proposed for "bending the cost curve" in the House and Senate versions of reform-the tax on high-cost plans and the new advisory board that could fast-track payment changes in Medicare that would reduce spending-are also included in the final legislation, but in muted form.

    Research in Healthcare Epidemiology and Antimicrobial Stewardship (HE&AS) is rapidly expanding with the involvement of researchers from varied countries and backgrounds. Researchers must use scientific methods that will provide the strongest evidence to advance healthcare epidemiology, but there are limited resources for information on specific aspects of HE&AS research or easy ways to access examples of studies using specific methods with HE&AS. In response to this need, the SHEA Research Committee has developed a series of white papers on research methods in HE&AS. The objective of this series is to promote rigorous healthcare epidemiology research by summarizing critical components, practical considerations, and pitfalls of commonly used research methods.

    Background Advanced mobile communications and portable computation are now combined in handheld devices called “smartphones”, which are also capable of running third-party software. The number of smartphone users is growing rapidly, including among healthcare professionals. The purpose of this study was to classify smartphone-based healthcare technologies as discussed in academic literature according to their functionalities, and summarize articles in each category. Methods In April 2011, MEDLINE was searched to identify articles that discussed the design, development, evaluation, or use of smartphone-based software for healthcare professionals, medical or nursing students, or patients. A total of 55 articles discussing 83 applications were selected for this study from 2,894 articles initially obtained from the MEDLINE searches. Results A total of 83 applications were documented: 57 applications for healthcare professionals focusing on disease diagnosis (21), drug reference (6), medical calculators (8), literature search (6), clinical communication (3), Hospital Information System (HIS) client applications (4), medical training (2) and general healthcare applications (7); 11 applications for medical or nursing students focusing on medical education; and 15 applications for patients focusing on disease management with chronic illness (6), ENT-related (4), fall-related (3), and two other conditions (2). The disease diagnosis, drug reference, and medical calculator applications were reported as most useful by healthcare professionals and medical or nursing students. Conclusions Many medical applications for smartphones have been developed and widely used by health professionals and patients. The use of smartphones is getting more attention in healthcare day by day. Medical applications make smartphones useful tools in the practice of evidence-based medicine at the point of care, in addition to their use in mobile clinical communication.

    Given the potential role of economic information in healthcare decision making, it is of interest to assess its influence on decisions at a national or regional level (macro level), at a healthcare facility level (meso level) and at the healthcare provider level (micro level). This literature review summarises 36 empirical studies that examined the influence of economic evaluations on these three healthcare decision-making levels. Economic evaluations are considered useful and important; however, their direct influence on decision making (instrumental use) is moderate, especially at the macro and micro levels. A major influence was observed at the meso level, leading to the conclusion that economic evaluations have the most pronounced influence on decision making within healthcare organisations. However, unexpectedly, our literature search did not reveal an empirical study analysing the considerable influence of economic evaluations on decisions by the National Institute of Health and Clinical Excellence in the UK. Our findings indicate that results of economic evaluations cannot be considered the dominant decision criterion for healthcare decision makers at either the macro, meso or micro levels. Enlightenment use (where scientific evidence provides a background of information, ideas and concepts that affect the way policy makers view problems and solutions) of economic evaluations in decision making remains to be proven.

    We report experimental observations of the negative-group-velocity (v(g)) phenomenon in an integrated-optical two-port ring-resonator circuit. We demonstrate that when the v(g) is negative, the (main) peak of output pulse appears earlier than the peak of a reference pulse, while for a positive v(g), the situation is the other way around. We observed that a pulse splitting phenomenon occurs in the neighborhood of the critical-coupling point. This pulse splitting limits the maximum achievable delay and advancement of a single device as well as facilitating a smooth transition from highly advanced to highly delayed pulse, and vice versa, across the critical-coupling point.

    Advance care planning (ACP) increases the likelihood that individuals who are dying receive the care that they prefer. It also reduces depression and anxiety in family members and increases family satisfaction with the process of care. Honoring Choices Minnesota is an ACP program based on the Respecting Choices model of La Crosse, Wisconsin. The objective of this report is to describe the process, which began in 2008, of implementing Honoring Choices Minnesota in a large, diverse metropolitan area. All eight large healthcare systems in the metropolitan area agreed to participate in the project, and as of April 30, 2013, the proportion of hospitalized individuals 65 and older with advance care directives in the electronic medical record was 12.1% to 65.6%. The proportion of outpatients aged 65 and older was 11.6% to 31.7%. Organizations that had sponsored recruitment initiatives had the highest proportions of records containing healthcare directives. It was concluded that it is possible to reduce redundancy by recruiting all healthcare systems in a metropolitan area to endorse the same ACP model, although significantly increasing the proportion of individuals with a healthcare directive in their medical record requires a campaign with recruitment of organizations and individuals.

    Roman, Jesse

    2015-12-01

    The Commonwealth of Puerto Rico is an organized nonincorporated territory of the United States with a population of more than 3.5 million U.S. citizens. The island has been the focus of much recent attention due to the recent default on its debt (estimated at more than $70 billion), high poverty rates, and increasing unemployment. Less attention, however, has been given to the island's healthcare system, which many believe is on the verge of collapsing. Healthcare makes up 20% of the Puerto Rican economy, and this crisis affects reimbursement rates for physicians while promoting the disintegration of the island's healthcare infrastructure. A major contributor relates to a disparity in federal funding provided to support the island's healthcare system when compared with that provided to the states in the mainland and Hawaii. Puerto Rico receives less federal funding for healthcare than the other 50 states and the District of Columbia even though it pays its share of social security and Medicare taxes. To make matters worse, the U.S. Center for Medicaid and Medicare Services is planning soon to implement another 11% cut in Medical Advantage reimbursements. This disparity in support for healthcare is considered responsible for ∼$25 billion of Puerto Rico's total debt. The impact of these events on the health of Puerto Ricans in the island cannot be entirely predicted, but the loss of healthcare providers and diminished access to care are a certainty, and quality care will suffer, leading to serious implications for those with chronic medical disorders including respiratory disease.

    2005-01-01

    Many healthcare organization projects take more time and resources than planned and fail to deliver desired business outcomes. Healthcare IT is a major component of many projects and often undeservedly receives the blame for failure. Poor results are often not a result of faulty healthcare IT or poor project management or poor project execution alone. Many projects fail because of poor portfolio management--poor planning and management of the portfolio of initiatives designed to meet an organization's strategic goals. Because resources are limited, portfolio management enables organizations to more strategically allocate and manage their resources so care delivery, service delivery, and initiatives that advance organizations toward their strategic goals, including healthcare IT initiatives, can be accomplished at the levels of quality and service desired by an organization. Proper portfolio management is the essential foundation for program and project success and supports overall organization success. Without portfolio management, even programs and projects that execute flawlessly may not meet desired objectives. This article discusses the essential requirements for porfolio management. These include opportunity identification, return on investment (ROI) forecast, project prioritization, capacity planning (inclusive of human, financial, capital, and facilities resources), work scheduling, program and project management and execution, and project performance and value assessment. Portfolio management is essential to successful healthcare project execution. Theories are drawn from the Organizational Project Management Maturity Model (OPM3) work of the Project Management Institute and other leading strategy, planning, and organization change management research institutes.

    2015-01-01

    Background Healthcare expenditures in the United States exceed the healthcare expenditures of other countries, yet relatively unfavorable health outcomes persist. Despite the emergence of numerous evidence-based interventions, wide variations in clinical care have caused disparities in quality of care and cost. Comparative effectiveness and cost effectiveness research may better guide healthcare decisionmakers in determining which interventions work best, for which populations, under which conditions, and at what cost. Methods This article reviews national health policies that promote comparative effectiveness research (CER), healthcare decisionmaker roles in CER, methodological approaches to CER, and future implications of CER. Results This article provides a brief summary of CER health policy up to the Patient Protection and Affordable Care Act and its establishment of the Patient-Centered Outcomes Research Institute (PCORI). Through PCORI, participatory methods for engaging healthcare decisionmakers in the entire CER process have gained momentum as a strategy for improving the relevance of research and expediting the translation of research into practice. Well-designed, methodologically rigorous observational studies and randomized trials conducted in real-world settings have the potential to improve the quality, generalizability, and transferability of study findings. Conclusion Learning health systems and practice-based research networks provide the infrastructure for advancing CER methods, generating local solutions to high-quality cost-effective care, and transitioning research into implementation and dissemination science—all of which will ultimately guide health policy on clinical care, payment for care, and population health.

    2016-01-01

    Real-time personal health monitoring is gaining new ground with advances in wireless communications. Wireless body area networks (WBANs) provide a means for low-powered sensors, affixed either on the human body or in vivo, to communicate with each other and with external telecommunication networks. The healthcare benefits of WBANs include continuous monitoring of patient vitals, measuring postacute rehabilitation time, and improving quality of medical care provided in medical emergencies. This study sought to examine emerging trends in WBAN adoption in healthcare. To that end, a systematic literature survey was undertaken against the PubMed database. The search criteria focused on peer-reviewed articles that contained the keywords "wireless body area network" and "healthcare" or "wireless body area network" and "health care." A comprehensive review of these articles was performed to identify adoption dimensions, including underlying technology framework, healthcare subdomain, and applicable lessons-learned. This article benefits healthcare technology professionals by identifying gaps in implementation of current technology and highlighting opportunities for improving products and services.

    2009-01-01

    More than 500,000 premature infants are born in the United States every year. Preterm birth results in a multitude of negative adverse outcomes for children, including extended stays in the neonatal intensive care unit (NICU), developmental delays, physical and mental health/behavioral problems, increased medical utilization, and poor academic performance. In addition, parents of preterms experience a higher incidence of depression and anxiety disorders along with altered parent-infant interactions and overprotective parenting, which negatively impact their children. The costs associated with preterm birth are exorbitant. In 2005, it is estimated that preterm birth cost the United States $26.2 billion. The purpose of this study was to perform a cost analysis of the Creating Opportunities for Parent Empowerment (COPE) program for parents of premature infants, a manualized educational-behavioral intervention program comprising audiotaped information and an activity workbook that is administered to parents in 4 phases, the first phase commencing 2 to 4 days after admission to the NICU. Findings indicated that the COPE program resulted in cost savings of at least $4864 per infant. In addition to improving parent and child outcomes, routine implementation of COPE in NICUs across the United States could save the healthcare system more than $2 billion per year. PMID:19092521

    2015-01-01

    Increasing prevalences, morbidity, premature mortality and medical needs associated with non-communicable diseases and conditions (NCDs) have reached epidemic proportions and placed a major drain on healthcare systems and global economies. Added to this are the challenges presented by overuse of antibiotics and increased antibiotic resistance. Solutions are needed that can address the challenges of NCDs and increasing antibiotic resistance, maximize preventative measures, and balance healthcare needs with available services and economic realities. Microbiome management including microbiota seeding, feeding, and rebiosis appears likely to be a core component of a path toward sustainable healthcare. Recent findings indicate that: (1) humans are mostly microbial (in terms of numbers of cells and genes); (2) immune dysfunction and misregulated inflammation are pivotal in the majority of NCDs; (3) microbiome status affects early immune education and risk of NCDs, and (4) microbiome status affects the risk of certain infections. Management of the microbiome to reduce later-life health risk and/or to treat emerging NCDs, to spare antibiotic use and to reduce the risk of recurrent infections may provide a more effective healthcare strategy across the life course particularly when a personalized medicine approach is considered. This review will examine the potential for microbiome management to contribute to sustainable healthcare. PMID:27417751

However, the need for proper healthcare waste management has been gaining recognition slowly due to the substantial disease burdens associated with poor practices, including exposure to infectious agents and toxic substances. Despite the magnitude of the problem, practices, capacities and policies in many countries in dealing with healthcare waste disposal, especially developing nations, is inadequate and requires intensification. This paper looks upon aspects to drive improvements to the existing healthcare waste management situation. The paper places recommendation based on a 12 country study reflecting the current status. The paper does not advocate for any complex technology but calls for changes in mindset of all concerned stakeholders and identifies five important aspects for serious consideration. Understanding the role of governments and healthcare facilities, the paper also outlines three key areas for prioritized action for both parties - budget support, developing policies and legislation and technology and knowledge management.

  20. Shifting subjects of health-care: placing "medical tourism" in the context of Malaysian domestic health-care reform.

    "Medical tourism" has frequently been held to unsettle naturalised relationships between the state and its citizenry. Yet in casting "medical tourism" as either an outside "innovation" or "invasion," scholars have often ignored the role that the neoliberal retrenchment of social welfare structures has played in shaping the domestic health-care systems of the "developing" countries recognised as international medical travel destinations. While there is little doubt that "medical tourism" impacts destinations' health-care systems, it remains essential to contextualise them. This paper offers a reading of the emergence of "medical tourism" from within the context of ongoing health-care privatisation reform in one of today's most prominent destinations: Malaysia. It argues that "medical tourism" to Malaysia has been mobilised politically both to advance domestic health-care reform and to cast off the country's "underdeveloped" image not only among foreign patient-consumers but also among its own nationals, who are themselves increasingly envisioned by the Malaysian state as prospective health-care consumers.

  1. Implementing healthcare information security: standards can help.

    Using widely spread common approaches to systems security in health dedicated controlled environments, a level of awareness, confidence and acceptance of relevant standardisation is evaluated. Patients' information is sensitive, so putting appropriate organisational techniques as well as modern technology in place to secure health information is of paramount importance. Mobile devices are becoming the top priorities in advanced information security planning with healthcare environments being no exception. There are less and less application areas in healthcare without having a need for a mobile functionality which represents an even greater information security challenge. This is also true in emergency treatments, rehabilitation and homecare just to mention a few areas outside hospital controlled environments. Unfortunately quite often traditional unsecured communications principles are still in routine use for communicating sensitive health related information. The security awareness level with users, patients and care professionals is not high enough so potential threats and risks may not be addressed and the respective information security management is therefore weak. Standards like ISO/IEC 27000 ISMS family, the ISO/IEC 27799 information security guidelines in health are often not well known, but together with legislation principles such as HIPAA, they can help.

    The rapidly expanding field of big data analytics has started to play a pivotal role in the evolution of healthcare practices and research. It has provided tools to accumulate, manage, analyze, and assimilate large volumes of disparate, structured, and unstructured data produced by current healthcare systems. Big data analytics has been recently applied towards aiding the process of care delivery and disease exploration. However, the adoption rate and research development in this space is still hindered by some fundamental problems inherent within the big data paradigm. In this paper, we discuss some of these major challenges with a focus on three upcoming and promising areas of medical research: image, signal, and genomics based analytics. Recent research which targets utilization of large volumes of medical data while combining multimodal data from disparate sources is discussed. Potential areas of research within this field which have the ability to provide meaningful impact on healthcare delivery are also examined. PMID:26229957

    Although Romania has a long-lasting tradition in organized medical healthcare, in the last two decades the Romanian healthcare system has been undergoing a perpetual transition with negative effects on all parties involved. The lack of long-term strategic vision, the implementation of initiatives without any impact studies, hence the constant short-term approach from the policy makers, combined with the "inherited" low allocation from GDP to the healthcare system have contributed significantly to its current evolution. Currently, most measures taken are of the "fire-fighting" type, rather than looking to the broader, long time perspective. There should be no wonder then, that predictive and preventive services do not get the proper attention and support. Patient and physicians should step in and take action in regulating a system that was originally designed for them. But until this happens, the organizations with leadership skills and vision need to take action-and this has already started. PMID:23199172

  4. Waste, Economists and American Healthcare

    2013-01-01

    Twenty-five years ago, Uwe Reinhardt pointed out that sheer bureaucratic waste, particularly in the private sector, accounted for much of the extraordinarily high cost of American health-care. Last year an expert panel of the Institute of Medicine reconfirmed his point, estimating that in 2009, administrative waste accounted for $190 billion out of a total of $765 billion in various forms of waste – 31% of overall American spending on healthcare. Reinhardt recently noted a peculiar schizophrenia among American economists, simultaneously deploring this monumental waste while celebrating the contribution of healthcare, and particularly medical research, to the American economy. The apparent paradox may arise from a confusion between the meanings of “value” in economic and everyday language, and from economists' tendency to create pseudo-aggregates of diverse and non-commensurate entities.

    Rare diseases are often life-limiting conditions, the majority of which require constant caregiving needs. The realization of a spectrum of palliative care throughout the trajectory of rare diseases could ensure individualized and caregiver-focused approaches to the care of patients and families. In June 2015, the National Institute of Nursing Research (NINR), the lead institute at the National Institutes of Health for end-of-life research, in conjunction with the National Center for Advancing Translational Sciences, Office of Rare Diseases Research (ORDR) held an interdisciplinary workshop on the unique challenges of caregiving and palliative care in adult and pediatric rare diseases. The panel identified gaps in current knowledge, and afforded suggestions for research opportunities in palliative care science to improve the care of individuals with serious, advanced, rare diseases and their caregivers. This meeting provided an in-depth opportunity to incorporate new concepts into palliative and end-of-life care for individuals with a range of rare diseases and their caregivers. This report presents a summary of the workshop. PMID:27249541

    FASB statements and SEC guidelines give direction as to how healthcare organizations should account for their asset retirement obligations (AROs) where environmental issues are concerned. A key consideration is that current costs associated with environmental problems, such as encapsulating asbestos, are to be accounted for as part of an asset's cost and depreciated over the asset's remaining life.

    Many chaplains and most chaplaincy programs in the United States – with encouragement from their accrediting organization, the Association for Clinical Pastoral Education (ACPE) – have begun to assume a more proactive stance toward patients, healthcare professionals, and healthcare facilities. Some chaplains and chaplaincy programs have begun to engage in activities that have ranged from initiating conversations with and perusing the medical records of patients who have not requested their services to proposing that they be permitted to do “spiritual assessments” on patients – in some instances whether these patients have been explicitly informed and have agreed to this beforehand. Moreover, many chaplains and chaplaincy programs have begun to assume that chaplains are full-fledged members of the healthcare team, complete with access to patients' medical records both to gather information and to make notations of their own. It would appear that such novel activities are being justified by a questionable set of claims and assumptions that includes: (1) the claim that chaplains have a spiritual – as opposed to purely religious – expertise that entitles them to interact with patients and/or significant others (even those who have not requested a chaplain) – presumably without in the least compromising patient autonomy or the confidentiality of the patient/healthcare professional relationship; (2) the assumption that the terms “spirituality” and “religiosity” mutually entail one another; (3) the claim that the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) mandates “spiritual assessments” (which it does not); (4) the assumption that chaplains are full-fledged members of the healthcare team; and (5) the claim that chaplains must, therefore, be permitted access to patients and patients' medical records both to gather information and to make notations of their own. We consider such claims and assumptions disquieting

    The physical environment has a significant impact on health and safety; however, hospitals have not been designed with the explicit goal of enhancing patient safety through facility design. In April 2002, St Joseph's Community Hospital of West Bend, a member of SynergyHealth, brought together leaders in healthcare and systems engineering to develop a set of safety‐driven facility design recommendations and principles that would guide the design of a new hospital facility focused on patient safety. By introducing safety‐driven innovations into the facility design process, environmental designers and healthcare leaders will be able to make significant contributions to patient safety.

    Healthcare associated infections (HAI) are among the major complications of modern medical therapy. The most important HAIs are those related to invasive devices: central line-associated bloodstream infections (CLABSI), catheter-associated urinary tract infections (CAUTI), ventilator-associated pneumonia (VAP) as well as surgical site infections (SSI). HAIs are associated with significant mortality, morbidities and increasing healthcare cost. The cited case-fatality rate ranges from 2.3% to 14.4% depending on the type of infection. In this mini-review, we shed light on these aspects as well as drivers to decrease HAIs. PMID:24861643

    Systemic sclerosis (SSc) is an autoimmune disease characterized by immune disorders, vascular obliteration, excessive extracellular matrix deposition, skin fibrosis, and further pathological change of internal organs. To date, the exact etiology of this complicated disease remains unknown. Over the past few years, the roles of epigenetic modifications caused by environmental factors have been intensively studied in relation to the disease pathogenesis, and important advances have been made. This review focuses on the new advances of microRNAs (miRNAs) in the field of SSc research, including the upstream regulatory factors of miRNAs, the downstream targets, and the feedback mechanisms between miRNAs and their targets. We also discussed the correlation of miRNAs and DNA methylation, the miRNAs and the gene polymorphism. Overall, the findings presented in this review illustrated how miRNAs play important roles in the pathogenesis of SSc. However, several unanswered questions continue to impede our understanding of this complex disease. Future research should focus on the identification of new biomarkers for early diagnosis and prognosis, which will help us improve the clinical treatment of patients with SSc. In addition, we discussed the challenges of miRNA study in SSc in the future. Since the miRNA injection may be a promising therapeutic approach for SSc treatment, one of the challenges in the future is to evaluate the therapeutic effects of miRNA and anti-miRNAs using SSc model animals. In light of the fact that one miRNA can target many mRNAs, and one mRNA is targeted by many miRNAs, the effect of miRNA changes on other gene expression should be investigated to evaluate the treatment safety of miRNA injection in vivo.

    Advance care planning (ACP), involving discussions between patients, families and healthcare professionals on future healthcare decisions, in advance of anticipated impairment in decision-making capacity, improves satisfaction and end-of-life care while respecting patient autonomy. It usually results in the creation of a written advanced care directive (ACD). This systematic review examines the impact of ACP on several outcomes (including symptom management, quality of care and healthcare utilisation) in older adults (>65years) across all healthcare settings. Nine randomised controlled trials (RCTs) were identified by searches of the CINAHL, PubMed and Cochrane databases. A total of 3646 older adults were included (range 72-88 years). Seven studies were conducted with community dwellers and the other two RCTs were conducted in nursing homes. Most studies did not implement a standardised ACD, or measure the impact on quality of end-of-life care or on the death and dying experience. All studies had some risk of bias, with most scoring poorly on the Oxford Quality Scale. While ACP interventions are well received by older adults and generally have positive effects on outcomes, this review highlights the need for well-designed RCTs that examine the economic impact of ACP and its effect on quality of care in nursing homes and other sectors.

    Translational cancer research is highly dependent of large series of cases including high quality samples and their associated data. Comprehensive Cancer Centers should be involved in networks to enable large-scale multi-center research projects between the centers [Ringborg, U., de Valeriola, D., van Harten, W., Llombart-Bosch, A., Lombardo, C., Nilsson, K., Philip, T., Pierotti, M.A., Riegman, P., Saghatchian, M., Storme, G., Tursz, T., Verellen, D, 2008. Improvement of European translational cancer research. Collaboration between comprehensive cancer centers. Tumori 94, 143-146.]. Combating cancer knows many frontiers. Research is needed for prevention as well as better care for those who have acquired the disease. This implies that human samples for cancer research need to be sourced from distinct forms of biobanking. An easier access to these samples for the scientific community is considered as the main bottleneck for research for health, and biobanks are the most adequate site to try to resolve this issue [Ozols, R.F., Herbst, R.S., Colson, Y.L., Gralow, J., Bonner, J., Curran Jr., W.J., Eisenberg, B.L., Ganz, P.A., Kramer, B.S., Kris, M.G., Markman, M., Mayer, R.J., Raghavan, D., Reaman, G.H., Sawaya, R., Schilsky, R.L., Schuchter, L.M., Sweetenham, J.W., Vahdat, L.T., Winn, R.J., and the American Society of Clinical Oncology, 2007.

    Enterprise resource planning (ERP) software applications are designed to facilitate the systemwide integration of complex processes and functions across a large enterprise consisting of many internal and external constituents. Although most currently available ERP applications generally are tailored to the needs of the manufacturing industry, many large healthcare systems are investigating these applications. Due to the significant differences between manufacturing and patient care, ERP-based systems do not easily translate to the healthcare setting. In particular, the lack of clinical standardization impedes the use of ERP systems for clinical integration. Nonetheless, an ERP-based system can help a healthcare organization integrate many functions, including patient scheduling, human resources management, workload forecasting, and management of workflow, that are not directly dependent on clinical decision making.

    Social networks provide a channel through which health policies and programmes can affect those with close social ties to the intended beneficiaries. We provide experimental evidence on the indirect effects of heavily subsidised healthcare. By exploiting data on 2151 households from a randomised study conducted in a rural district of Ghana in 2005, we estimate the extent to which social networks, defined by religion, influence the uptake of primary care services. We find that people socially connected to households with subsidised care are less likely to use primary care services despite the fact that the direct effect of the intervention is positive. We extend the empirical analysis to consider the implications of these changes in behaviour for welfare but find no evidence of indirect effects on child health and healthcare spending. In the context of this study, the findings highlight the potential for healthcare subsidies to have unintended consequences. PMID:26409167

    High healthcare cost has drawn much attention and healthcare service providers (HSPs) are expected to deliver high-quality and consistent care. Therefore, an intimate understanding of the most desirable experience from a patient's and/or family's perspective as well as effective mapping and communication of such findings should facilitate HSPs' efforts in attaining sustainable competitive advantage in an increasingly discerning environment. This study describes (a) the critical quality attributes (CQAs) of the experience desired by patients and (b) the application of two visualization tools that are relatively new to the healthcare sector, namely the "spider-web diagram" and "promotion and detraction matrix." The visualization tools are tested with primary data collected from telephone surveys of 1,800 patients who had received care during calendar year 2005 at 6 of 61 hospitals within St. Louis, Missouri-based, Ascension Health. Five CQAs were found by factor analysis. The spider-web diagram illustrates that communication and empowerment and compassionate and respectful care are the most important CQAs, and accordingly, the promotion and detraction matrix shows those attributes that have the greatest effect for creating promoters, preventing detractors, and improving consumer's likelihood to recommend the healthcare provider.

    A recently published article on corruption in Indian healthcare in the BMJ has triggered a hot debate and numerous responses (1, 2, 3, 4). We do agree that corruption in Indian healthcare is a colossal issue and needs to be tackled urgently (5). However, we want to highlight that corruption in healthcare is not a local phenomenon confined to the Indian subcontinent, though India does serve as a good case study and intervention area due to the magnitude of the problem and the country's large population (6). Good governance, strict rules, transparency and zero tolerance are some of the strategies prescribed everywhere to tackle corruption. However, those entrusted with implementing good governance and strict rules in India need to go through a process of introspection to carry out their duties in a responsible fashion. At present, it looks like a no-win situation. In this article, we recommend education in medical ethics as the major intervention for dealing with corruption in healthcare. PMID:26592785

    Perceptions of healthcare quality are lower among foreign- than US-born individuals. The objective of the study was to identify possible explanations for this disparity. Data were from 6202 respondents to cycles 1 and 2 of the Health Information National Trends Survey 4 conducted 2011-2013, including 5425 US-born and 777 foreign-born respondents. Perceived quality of healthcare was lower among foreign-born than US-born respondents, accounted for, to some degree (19.5 %), by foreign-born respondents experiencing relatively less patient-centered healthcare provider communication than US-born respondents. More patient-centered provider communication was associated with receiving higher quality healthcare in all respondents. Having a regular provider was associated with perceived quality of care in foreign-born but not US-born respondents, and the reverse was true for frequency of care. Patient centered provider communication and continuity of care may be key targets for improving quality of care for foreign-born individuals. PMID:25957045

    Purpose - The purpose of this paper is to capture factors behind professional views of indicator usefulness as a common structure for assessing healthcare performance and their important characteristics to design limited key performance indicators (PIs) for holistic hospital management. Design/methodology/approach - Two surveys were conducted using self-administered questionnaires, in which hospital manager/staff respondents were asked to rate the 52 PIs' usefulness. In total, 228 manager and 894 staff responses were collected. Findings - Eight factors were elicited from manager and staff responses as performance measures with 72 percent cumulative variance accounted for. Hospital managers and staff showed similar performance measure perceptions: high-utility acknowledgment on safety, operational efficiency and patient/employee satisfaction but relatively low-employee development concerns. Manager indicator usefulness perceptions were rather homogeneous and significantly higher than staff for almost all performance measures. Practical implications - Homogeneous manager views mean that a single key PI set for hospital management may be established regardless of hospital attributes. The following aspects may be measures that should be managed in a healthcare organization based on their key PIs: patient/employee safety, operational efficiency, financial effectiveness and patient/employee satisfaction. Originality/value - This is a pilot study on hospital management PIs in Japan. The eight-dimensional factor structure and findings about healthcare provider perceptions may be useful for healthcare management. PMID:27477935

    Purpose - The purpose of this paper is to analyze two case studies with a trust matrix tool, to identify trust issues related to electronic health records. Design/methodology/approach - A qualitative research approach is applied using two case studies. The data analysis of these studies generated a problem list, which was mapped to a trust matrix. Findings - Results demonstrate flaws in current practices and point to achieving balance between organizational, person and technology trust perspectives. The analysis revealed three challenge areas, to: achieve higher trust in patient-focussed healthcare; improve communication between patients and healthcare professionals; and establish clear terminology. By taking trust into account, a more holistic perspective on healthcare can be achieved, where trust can be obtained and optimized. Research limitations/implications - A trust matrix is tested and shown to identify trust problems on different levels and relating to trusting beliefs. Future research should elaborate and more fully address issues within three identified challenge areas. Practical implications - The trust matrix's usefulness as a tool for organizations to analyze trust problems and issues is demonstrated. Originality/value - Healthcare trust issues are captured to a greater extent and from previously unchartered perspectives. PMID:27477934

  4. American Geriatrics Society feeding tubes in advanced dementia position statement.

    PubMed

    2014-08-01

    When eating difficulties arise, feeding tubes are not recommended for older adults with advanced dementia. Careful hand feeding should be offered because hand feeding has been shown to be as good as tube feeding for the outcomes of death, aspiration pneumonia, functional status, and comfort. Moreover, tube feeding is associated with agitation, greater use of physical and chemical restraints, healthcare use due to tube-related complications, and development of new pressure ulcers. Efforts to enhance oral feeding by altering the environment and creating patient-centered approaches to feeding should be part of usual care for older adults with advanced dementia. Tube feeding is a medical therapy that an individual's surrogate decision-maker can decline or accept in accordance with advance directives, previously stated wishes, or what it is thought the individual would want. It is the responsibility of all members of the healthcare team caring for residents in long-term care settings to understand any previously expressed wishes of the individuals (through review of advance directives and with surrogate caregivers) regarding tube feeding and to incorporate these wishes into the care plan. Institutions such as hospitals, nursing homes, and other care settings should promote choice, endorse shared and informed decision-making, and honor preferences regarding tube feeding. They should not impose obligations or exert pressure on individuals or providers to institute tube feeding. PMID:25039796

    A healthcare utilization survey was conducted as a component of the Typhoid Fever Surveillance in Africa Program (TSAP). The findings of this survey in Madagascar contrasted with those in other sites of the program; namely, only 30% of the population sought healthcare at the government-provided healthcare facilities for fever. These findings promoted us to determine the drivers and barriers in accessing and utilizing healthcare in Madagascar. Here we review the results of the TSAP healthcare utilization initiative and place them in the context of the current organization of the Madagascan healthcare system. Our work highlights the demands of the population for access to appropriate healthcare and the need for novel solutions that can quickly provide an affordable and sustainable basic healthcare infrastructure until a government-funded scheme is in place.

    Objective While living overseas in another culture, retirees need to adapt to a new environment but often this causes difficulties, particularly among those elderly who require healthcare services. This study examines factors affecting healthcare service utilisation among Japanese retirees in Malaysia. Design We conducted 6 focus group discussions with Japanese retirees and interviewed 8 relevant medical services providers in-depth. Guided by the Andersen Healthcare Utilisation Model, we managed and analysed the data, using QSR NVivo 10 software and the directed content analysis method. Setting We interviewed participants at Japan Clubs and their offices. Participants 30 Japanese retirees who live in Kuala Lumpur and Ipoh, and 8 medical services providers. Results We identified health beliefs, medical symptoms and health insurance as the 3 most important themes, respectively, representing the 3 dimensions within the Andersen Healthcare Utilisation Model. Additionally, language barriers, voluntary health repatriation to Japan and psychological support were unique themes that influence healthcare service utilisation among Japanese retirees. Conclusions The healthcare service utilisation among Japanese retirees in Malaysia could be partially explained by the Andersen Healthcare Utilisation Model, together with some factors that were unique findings to this study. Healthcare service utilisation among Japanese retirees in Malaysia could be improved by alleviating negative health beliefs through awareness programmes for Japanese retirees about the healthcare systems and cultural aspects of medical care in Malaysia.

    Healthcare applications are considered as promising fields for wireless sensor networks, where patients can be monitored using wireless medical sensor networks (WMSNs). Current WMSN healthcare research trends focus on patient reliable communication, patient mobility, and energy-efficient routing, as a few examples. However, deploying new technologies in healthcare applications without considering security makes patient privacy vulnerable. Moreover, the physiological data of an individual are highly sensitive. Therefore, security is a paramount requirement of healthcare applications, especially in the case of patient privacy, if the patient has an embarrassing disease. This paper discusses the security and privacy issues in healthcare application using WMSNs. We highlight some popular healthcare projects using wireless medical sensor networks, and discuss their security. Our aim is to instigate discussion on these critical issues since the success of healthcare application depends directly on patient security and privacy, for ethic as well as legal reasons. In addition, we discuss the issues with existing security mechanisms, and sketch out the important security requirements for such applications. In addition, the paper reviews existing schemes that have been recently proposed to provide security solutions in wireless healthcare scenarios. Finally, the paper ends up with a summary of open security research issues that need to be explored for future healthcare applications using WMSNs. PMID:22368458

    This article examines the healthcare regionalization process in the Brazilian states in the period from 2007 to 2010, seeking to identify the conditions that favor or impede this process. Referential analysis of public policies and especially of historical institutionalism was used. Three dimensions sum up the conditioning factors of regionalization: context (historical-structural, political-institutional and conjunctural), directionality (ideology, object, actors, strategies and instruments) and regionalization features (institutionality and governance). The empirical research relied mainly on the analysis of official documents and interviews with key actors in 24 states. Distinct patterns of influence in the states were observed, with regionalization being marked by important gains in institutionality and governance in the period. Nevertheless, inherent difficulties of the contexts prejudice greater advances. There is a pressing need to broaden the territorial focus in government planning and to integrate sectorial policies for medium and long-term regional development in order to empower regionalization and to overcome obstacles to the access to healthcare services in Brazil.

    Instrumental developments in the measurement of multiple isotopes of methane (12CH4, 13CH4 and 12CH3D) are presented. A first generation 8-micron instrument quantifies 12CH4 and 13CH4 at a 1-second rate via tunable infrared direct absorption spectroscopy (TILDAS). A second generation instrument uses two 3-micron intraband cascade lasers in an Aerodyne dual laser chassis for simultaneous measurement of 12CH4, 13CH4 and 12CH3D. Sensitivity and noise performance improvements are examined. The isotopic signature of methane provides valuable information for emission source identification of this greenhouse gas. A first generation spectrometer has been deployed in the field on a mobile laboratory along with a sophisticated 4-tank calibration system. Calibrations are done on an agressive schedule, allowing for the correction of measured isotope ratios to an absolute isotope scale. Distinct isotopic signatures are found for a number of emission sources in the Denver-Julesburg Basin: oil and gas gathering stations, compressor stations and processing plants; a municipal landfill, and dairy/cattle operations. The isotopic signatures are compared with measured ethane/methane ratios. These direct absorption measurements have larger uncertainties than samples measured via gas chromatography-mass spectrometry, but have several advantages over canister sampling methods: individual sources of short duration are easier to isolate; calibrated isotope ratio results are available immediately; replicate measurements on a single source are easily performed; and the number of sources sampled is not limited by canister availability and processing time.

    ObjectiveThis study was designed to evaluate the clinical application of preoperative auxiliary embolization for juvenile nasopharyngeal angiofibroma (JNA) by direct puncture embolization (DPE) of the tumor in combination with transarterial embolization (TAE). The study included 22 patients. An 18-gauge needle was used to puncture directly into the tumor, and 20-25 % N-butyl cyanoacrylate was injected under the guidance of fluoroscopy after confirming the placement of the needle into the JNA and no leaking into the surrounding tissue. Tumors were obstructed later via TAE. The supplying arteries of JNA were from branches of the internal carotid and external carotid arteries. Control angiography showed the obliteration of contrast stain in the entire tumor mass and the distal supplying arteries disappeared after DPE in combination with TAE. Surgical resection was performed within 4 days after embolization and none of the patients required blood transfusion. The use of DPE in combination with TAE was a safe, feasible, and efficacious method. It can devascularize effectively the JNAs and reduce intraoperative bleeding when JNAs are extirpated.

    In 2000, acquired immunodeficiency syndrome (AIDS) overtook tuberculosis (TB) as the world's leading infectious cause of adult deaths. In affluent countries, however, AIDS mortality has dropped sharply, largely because of the use of highly active antiretroviral therapy (HAART). Antiretroviral agents are not yet considered essential medications by international public health experts and are not widely used in the poor countries where human immunodeficiency virus (HIV) takes its greatest toll. Arguments against the use of HAART have mainly been based on the high cost of medications and the lack of the infrastructure necessary for using them wisely. We re- examine these arguments in the setting of rising AIDS mortality in developing countries and falling drug prices, and describe a small community-based treatment programme based on lessons gained in TB control. With the collaboration of Haitian community health workers experienced in the delivery of home-based and directly observed treatment for TB, an AIDS-prevention project was expanded to deliver HAART to a subset of HIV patients deemed most likely to benefit. The inclusion criteria and preliminary results are presented. We conclude that directly observed therapy (DOT) with HAART, "DOT-HAART", can be delivered effectively in poor settings if there is an uninterrupted supply of high-quality drugs. PMID:11799447

    Objectives Many countries try to efficiently deliver high quality healthcare services at lower and manageable costs where healthcare information and communication technologies (ICT) standardisation may play an important role. New Zealand provides a good model of healthcare ICT standardisation. The purpose of this study was to review the current healthcare ICT standardisation and progress in New Zealand. Methods This study reviewed the reports regarding the healthcare ICT standardisation in New Zealand. We also investigated relevant websites related with the healthcare ICT standards, most of which were run by the government. Then, we summarised the governance structure, standardisation processes, and their output regarding the current healthcare ICT standards status of New Zealand. Results New Zealand government bodies have established a set of healthcare ICT standards and clear guidelines and procedures for healthcare ICT standardisation. Government has actively participated in various enactments of healthcare ICT standards from the inception of ideas to their eventual retirement. Great achievements in eHealth have already been realized, and various standards are currently utilised at all levels of healthcare regionally and nationally. Standard clinical terminologies, such as International Classification of Diseases (ICD) and Systematized Nomenclature of Medicine - Clinical Terms (SNOMED-CT) have been adopted and Health Level Seven (HL7) standards are actively used in health information exchanges. Conclusions The government to New Zealand has well organised ICT institutions, guidelines, and regulations, as well as various programs, such as e-Medications and integrated care services. Local district health boards directly running hospitals have effectively adopted various new ICT standards. They might already be benefiting from improved efficiency resulting from healthcare ICT standardisation. PMID:26279950

    2009-01-01

    Today’s medicine is in the midst of an undeniable crisis. Calls to reform healthcare are in the forefront of economic and political discussions worldwide. Economic pressures reduce the amount of time physicians can spend with patients contributing to burnout among medical staff and endangering the patient iatrogenically. Politicians are getting involved as the public is calling for more affordable healthcare. A new paradigm must be embraced in order to address all aspects of this dilemma. It is clear that science and technology have resulted in vastly improved understanding, diagnosis, and treatment of disease, but the emphasis on science and technology to the exclusion of other elements of healing has also served to limit the development of a model that humanizes healthcare. The healing of a patient must include more than the biology and chemistry of their physical body; by necessity, it must include the mental, emotional and spiritual aspects. Because of these challenges, the development of an integral healthcare system that is rooted in appropriate regulation and supported by rigorous scientific evidence is the direction that many models of integrative healthcare are moving towards in the 21st century.

    2015-12-01

    Healthcare is in a period significant transformational activity through the accelerated adoption of healthcare technologies, new reimbursement systems that emphasize shared savings and care coordination, and the common place use of mobile technologies by patients, providers, and others. The complexity of healthcare creates barriers to transformational activity and has the potential to inhibit the desired paths toward change envisioned by policymakers. Methods for understanding how change is occurring within this complex environment are important to the evaluation of delivery system reform and the role of technology in healthcare transformation. This study examines the use on an integrative review methodology to evaluate the healthcare literature for evidence of technology transformation in healthcare. The methodology integrates the evaluation of a broad set of literature with an established evaluative framework to develop a more complete understanding of a particular topic. We applied this methodology and the framework of punctuated equilibrium (PEq) to the analysis of the healthcare literature from 2004 to 2012 for evidence of technology transformation, a time during which technology was at the forefront of healthcare policy. The analysis demonstrated that the established PEq framework applied to the literature showed considerable potential for evaluating the progress of policies that encourage healthcare transformation. Significant inhibitors to change were identified through the integrative review and categorized into ten themes that describe the resistant structure of healthcare delivery: variations in the environment; market complexity; regulations; flawed risks and rewards; change theories; barriers; ethical considerations; competition and sustainability; environmental elements, and internal elements. We hypothesize that the resistant nature of the healthcare system described by this study creates barriers to the direct consumer involvement and engagement

  2. Development of advanced direct perception displays for nuclear power plants to enhance monitoring, control and fault management

    1997-08-01

    Traditional Single-Sensor-Single Indicator (SSSI) displays are poorly matched to the cognitive abilities of operators, especially for large and complex systems. It is difficult for operators to monitor very large arrays of displays and controls, and to integrate the information displayed therein. In addition, standard operating procedures (SOPs) are bulky (running to many hundreds of pages) and difficult to use, and operators may become lost. For these reasons, and also because it is becoming increasingly difficult to find replacements for aging hardware components, there is a trend towards computerized graphical interfaces for nuclear power plants (NPPs). There is, however, little rational theory for display design in this domain. This report describes some recent theoretical developments and shows how to develop displays which will greatly reduce the cognitive load on the operator and allow the use of perceptual rather than cognitive mechanisms while using SON and to support state diagnosis and fault management. The report outlines the conceptual framework within which such a new approach could be developed, and provides an example of how the operating procedures for the start-up sequence of a NPP could be realized. A detailed description of a set of displays for a graphical interface for the SON of the feedwater system is provided as an example of how the proposed approach could be realized, and a general account of how it would fit into the overall start-up sequence is given. Examples of {open_quotes}direct perception{close_quotes} or {open_quotes}ecological{close_quotes} configural state space displays to support the use of the proposed direct manipulation SOP interface are provided, and also a critical discussion which identifies some difficulties which may be anticipated should the general approach herein advocated be adopted.

    During the past decade, there has been a growing interest in competency-based performance systems for enhancing both individual and organizational performance in health professions education and the varied healthcare industry sectors. In 2003, the Institute of Medicine's report Health Professions Education: A Bridge to Quality called for a core set of competencies across the professions to ultimately improve the quality of healthcare in the United States. This article reviews the processes and outcomes associated with the development of the Health Leadership Competency Model (HLCM), an evidence-based and behaviorally focused approach for evaluating leadership skills across the professions, including health management, medicine, and nursing, and across career stages. The HLCM was developed from extensive academic research and widespread application outside healthcare. Early development included behavioral event interviewing, psychometric analysis, and cross-industry sector benchmarking. Application to healthcare was supported by additional literature review, practice analysis, expert panel inputs, and pilot-testing surveys. The model addresses three overarching domains subsuming 26 behavioral and technical competencies. Each competency is composed of prescriptive behavioral indicators, or levels, for development and assessment as individuals progress through their careers from entry-level to mid-level and advanced stages of lifelong development. The model supports identification of opportunities for leadership improvement in both academic and practice settings. PMID:19070333

    Nursing is the largest segment of the healthcare workforce, but over the next decade even more nurses will be required. Changing population demographics, new technologies, and evolving models of healthcare will stimulate expansion of nursing roles and the need for a highly educated nursing workforce. The current nursing workforce is aging, and large numbers of retirements are anticipated. By 2025, the United States is expected to experience a nursing shortage; in Hawai‘i this shortfall is forecast to be 3,311 professional nurses. Currently there are nine nursing programs across the state in public and private universities and colleges. These programs are partnering to implement the Institute of Medicine's recommendations for the future of nursing. In Hawai‘i, nursing practice is being expanded; different pathways to advanced nursing education are being implemented; and nurses are partnering with other groups to reshape healthcare. The Hawai‘i State Center for Nursing collects ongoing data on the nursing workforce to inform strategic planning. Current gaps in nursing specialty education include school health and mental health. The purpose of this paper is to provide an overview of Hawai‘i's nursing workforce in relationship to statewide population demographics, healthcare needs and gaps, and then outline steps being taken by the profession to address these needs and gaps while implementing the Institute of Medicine recommendations.

    The healthcare system is in crisis due to challenges including escalating costs, the inconsistent provision of care, an aging population, and high burden of chronic disease related to health behaviors. Mitigating this crisis will require a major transformation of healthcare to be proactive, preventive, patient-centered, and evidence-based with a focus on improving quality-of-life. Information technology, networking, and biomedical engineering are likely to be essential in making this transformation possible with the help of advances, such as sensor technology, mobile computing, machine learning, etc. This paper has three themes: 1) motivation for a transformation of healthcare; 2) description of how information technology and engineering can support this transformation with the help of computational models; and 3) a technical overview of several research areas that illustrate the need for mathematical modeling approaches, ranging from sparse sampling to behavioral phenotyping and early detection. A key tenet of this paper concerns complementing prior work on patient-specific modeling and simulation by modeling neuropsychological, behavioral, and social phenomena. The resulting models, in combination with frequent or continuous measurements, are likely to be key components of health interventions to enhance health and wellbeing and the provision of healthcare.

    There is considerable interest in the use of statistical process control (SPC) in healthcare. Although SPC is part of an overall philosophy of continual improvement, the implementation of SPC usually requires the production of control charts. However, as SPC is relatively new to healthcare practitioners and is not routinely featured in medical statistics texts/courses, there is a need to explain the issues involved in the selection and construction of control charts in practice. Following a brief overview of SPC in healthcare and preliminary issues, we use a tutorial-based approach to illustrate the selection and construction of four commonly used control charts (xmr-chart, p-chart, u-chart, c-chart) using examples from healthcare. For each control chart, the raw data, the relevant formulae and their use and interpretation of the final SPC chart are provided together with a notes section highlighting important issues for the SPC practitioner. Some more advanced topics are also mentioned with suggestions for further reading. PMID:18385409

    In this work, platinum-palladium (Pt-Pd) is assembled in-situ on the surface of porous silicon flour (PSiF) through chemical reduction of PtCl62-/PdCl42- and oxidation of the precursor solution SiF64-. The components and the morphological properties of the Pt-Pd on PSiF is investigated by means of transmission electron microscopy, energy dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and X-ray diffraction techniques. In the next stage, screen printed graphene electrode (SPGE) is prepared by electro-reduction of exfoliated graphene oxide at the surface of a screen printed carbon electrode (SPCE), which is subsequently characterized by FT-IR, Raman spectroscopy, FE-SEM, and electrochemical methods. Finally, a combination of Pt-Pd@PSi nanostructure and SPGE is used for the electro-oxidation of methanol in direct methanol fuel cell. The electrochemical results demonstrate that the Pt-Pd@PSiF-SPGE exhibits an excellent electrocatalytic activity for methanol oxidation. In addition, the electron transfer kinetic of methanol oxidation on Pt-Pd@PSiF-SPGE is investigated by electrochemical impedance spectroscopy. The results showed that the surface of Pt-Pd@PSiF-SPGE is not affected (poisoned) by intermediate products such as CO.

    A team approach involving several turbine engine companies using the concepts of simultaneous engi-neering has been used to successfully develop CMSX-4 ® alloy for turbine blade applications. CMSX-4 al-loy is a second-generation, single-crystal cast nickel-base superalloy containing 3% Re and approximately 70% volume fraction of γ. The high level of balanced properties determined by labora-tory evaluation has been confirmed during field testing of the Solarγ Mars T-14000 industrial gas turbine with CMSX-4 single-crystal (SX) blades in both the coated and bare condition. A similar collaborative ap-proach has resulted in the successful development of CM 186 LCγ alloy for complex, directionally solidi-fied (DS) columnar grain vane segments. CM 186 LC alloy is a second-generation DS columnar grain cast nickel-base superalloy containing 3% Re and approximately 65% volume fraction of γ. Excellent com-ponent producibility and quality is demonstrated. Turbine engine testing is scheduled to commence by the end of 1993.

    Acoustic data are presented from a 40 percent scale model of the four-bladed BO-105 helicopter main rotor, tested in a large aerodynamic wind tunnel. Rotor blade-vortex interaction (BVI) noise data in the low-speed flight range were acquired using a traversing in-flow microphone array. Acoustic results presented are used to assess the acoustic far field of BVI noise, to map the directivity and temporal characteristics of BVI impulsive noise, and to show the existence of retreating-side BVI signals. The characterics of the acoustic radiation patterns, which can often be strongly focused, are found to be very dependent on rotor operating condition. The acoustic signals exhibit multiple blade-vortex interactions per blade with broad impulsive content at lower speeds, while at higher speeds, they exhibit fewer interactions per blade, with much sharper, higher amplitude acoustic signals. Moderate-amplitude BVI acoustic signals measured under the aft retreating quadrant of the rotor are shown to originate from the retreating side of the rotor.

    A low NO(x) emissions combustor has been demonstrated in flame-tube tests. A multipoint, lean-direct injection concept was used. Configurations were tested that had 25- and 36- fuel injectors in the size of a conventional single fuel injector. An integrated-module approach was used for the construction where chemically etched laminates, diffusion bonded together, combine the fuel injectors, air swirlers and fuel manifold into a single element. Test conditions were inlet temperatures up to 810 K, inlet pressures up to 2760 kPa, and flame temperatures up to 2100 K. A correlation was developed relating the NO(x) emissions with the inlet temperature, inlet pressure, fuel-air ratio and pressure drop. Assuming that 10 percent of the combustion air would be used for liner cooling and using a hypothetical engine cycle, the NO(x) emissions using the correlation from flame-tube tests were estimated to be less than 20 percent of the 1996 ICAO standard.

    The United States' healthcare delivery model is undergoing significant change. Insurance and reimbursement models are rapidly evolving, federal allocations are shifting from specialty services to preventive and generalpractice services, and Accountable Care Organizations are gaining in prominence. One area of focus is on the perceived over-utilization of expensive services such as advanced imaging and, in some cases, radiation therapy. Reimbursement incentives are increasingly aimed at quality metrics, leading to an increased interest in the core concepts of High Reliability Organizations. With the shift in federal resources away from specialty services and the increasing prominence of Accountable Care Organizations, we will likely be challenged to re-assess our traditional model for delivering medical physics services. Medical physicists have a unique combination of education and training in physics principles, radiation physics applications in medicine, human anatomy, as well as safety analysis and quality control methods. An effective medical physicist recognizes that to advance the institution's mission, the medical physicist must join other professional leaders within the institution to provide clear direction and perspective for the entire team. To do that, we must first recognize the macro changes in our healthcare delivery system and candidly assess how the medical physics practice model can evolve in a prudent way to support the institution's objectives while maintaining the traditionally high level of quality and safety. This year's Professional Council Symposium will explore the many facets of the changing healthcare system and its potential impact on medical physics. Dr. Shine will provide an overview of the developing healthcare delivery and reimbursement models, with a focus on how the physician community has adapted to the changing objectives. Mr. White will describe recent changes in the reimbursement patterns for both imaging and radiation therapy

    The mobilisation of cohesive and effective groups of healthcare human resource is important in ensuring the success of healthcare organisations. However, forming the right team or coalition in healthcare organisations is not always straightforward due to various human factors. Traditional coalition formation approaches have been perceived as 'materialistic' or focusing too much on competency or pay-off. Therefore, to put prominence on the human aspects of working together, we present a cohesiveness-focused healthcare coalition formation methodology and framework that explores the possibilities of social networks, i.e. the relationship between various healthcare human resources, and adaptive resonance theory.

    Pierre-Gerlier Forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. In this commentary, I develop an additional argument in support of Forest et al view. Forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. Translation of externally generated innovation policy into local solutions is only one source of healthcare system change. We also need to build learning healthcare systems that can discover new health solutions at the frontline of care. Enhanced policy capacity staffing in those organizations will be key to building continuously learning health systems. PMID:26673470

    The convergence of science and technology in our dynamic digital era has resulted in the development of innovative digital health devices that allow easy and accurate characterization in health and disease. Technological advancements and the miniaturization of diagnostic instruments to modern smartphone-connected and mobile health (mHealth) devices such as the iECG, handheld ultrasound, and lab-on-a-chip technologies have led to increasing enthusiasm for patient care with promises to decrease healthcare costs and to improve outcomes. This 'hype' for mHealth has recently intersected with the 'real world' and is providing important insights into how patients and practitioners are utilizing digital health technologies. It is also raising important questions regarding the evidence supporting widespread device use. In this state-of-the-art review, we assess the current literature of mHealth and aim to provide a framework for the advances in mHealth by understanding the various device, patient, and clinical factors as they relate to digital health from device designs and patient engagement, to clinical workflow and device regulation. We also outline new strategies for generation and analysis of mHealth data at the individual and population-based levels. PMID:26873093

    1. In this, the second of a pair of papers on the structure of well-sorted natural granular material (sediment), new methods are described for automated measurements from images of sediment, of: 1) particle-size standard deviation (arithmetic sorting) with and without apparent void fraction; and 2) mean particle size in material with void fraction. A variety of simulations of granular material are used for testing purposes, in addition to images of natural sediment. Simulations are also used to establish that the effects on automated particle sizing of grains visible through the interstices of the grains at the very surface of a granular material continue to a depth of approximately 4 grain diameters and that this is independent of mean particle size. Ensemble root-mean squared error between observed and estimated arithmetic sorting coefficients for 262 images of natural silts, sands and gravels (drawn from 8 populations) is 31%, which reduces to 27% if adjusted for bias (slope correction between observed and estimated values). These methods allow non-intrusive and fully automated measurements of surfaces of unconsolidated granular material. With no tunable parameters or empirically derived coefficients, they should be broadly universal in appropriate applications. However, empirical corrections may need to be applied for the most accurate results. Finally, analytical formulas are derived for the one-step pore-particle transition probability matrix, estimated from the image's autocorrelogram, from which void fraction of a section of granular material can be estimated directly. This model gives excellent predictions of bulk void fraction yet imperfect predictions of pore-particle transitions.

  19. Advancing Solar Irradiance Measurement for Climate-Related Studies: Accurate Constraint on Direct Aerosol Radiative Effect (DARE)

    2011-01-01

    Earth's climate is driven primarily by solar radiation. As summarized in various IPCC reports, the global average of radiative forcing for different agents and mechanisms, such as aerosols or CO2 doubling, is in the range of a few W/sq m. However, when solar irradiance is measured by broadband radiometers, such as the fleet of Eppley Precision Solar Pyranometers (PSP) and equivalent instrumentation employed worldwide, the measurement uncertainty is larger than 2% (e.g., WMO specification of pyranometer, 2008). Thus, out of the approx. 184 W/sq m (approx.263 W/sq m if cloud-free) surface solar insolation (Trenberth et al. 2009), the measurement uncertainty is greater than +/-3.6 W/sq m, overwhelming the climate change signals. To discern these signals, less than a 1 % measurement uncertainty is required and is currently achievable only by means of a newly developed methodology employing a modified PSP-like pyranometer and an updated calibration equation to account for its thermal effects (li and Tsay, 2010). In this talk, we will show that some auxiliary measurements, such as those from a collocated pyrgeometer or air temperature sensors, can help correct historical datasets. Additionally, we will also demonstrate that a pyrheliometer is not free of the thermal effect; therefore, comparing to a high cost yet still not thermal-effect-free "direct + diffuse" approach in measuring surface solar irradiance, our new method is more economical, and more likely to be suitable for correcting a wide variety of historical datasets. Modeling simulations will be presented that a corrected solar irradiance measurement has a significant impact on aerosol forcing, and thus plays an important role in climate studies.

    There is a high incidence of skin disorders; these are also frequently encountered within Youth Healthcare (YHC). Some skin disorders are caused by an underlying disease, syndrome or child abuse. Therefore, detection of these causes in an early stage is important. Skin disorders can have a huge psychosocial impact on both child and parents. This is one of the reasons why prevention, detection, diagnosis, treatment, referral, and uniform advice and guidance are of great importance. The YHC Guideline examines counselling and advice, criteria for referral to primary or secondary healthcare, and skincare in general. It also describes the disorders that should be actively detected. The Guideline also looks at specific aspects of dark skins and ethnic diversity, and the impact of skin disorders on general wellbeing. The accompanying web-based tool includes argumentation and opinions from experts on more than 75 skin disorders, including illustrations and decision trees, to aid the drawing up of a treatment plan.

    Breast cancer is serious public health problem in countries of all resource levels. Although major advances in the detection and treatment of the disease have occurred in higher income settings, similar progress has been slow or scarce in most low- and middle-income countries (LMCs). The poorer outcomes in LMCs may relate to the limited capability of their healthcare systems (HCS) to provide successful early detection, diagnosis, and treatment of breast cancer. Impediments to better outcomes include insufficient numbers of appropriately trained healthcare workers, limited access to screening/treatment facilities, inadequate supplies of necessary drugs, and timeliness of treatment after diagnosis. Clearly, these HCS deficiencies are broader than the scope of the Breast Health Global Initiative (BHGI) and are not unique to the issue of breast cancer. To address issues in HCS that hinder the delivery of breast health services, the BHGI Healthcare Systems and Public Policy Panel explored the HCS structures and function needed to operate a breast care program (BCP). Like with all BHGI guidelines, those proposed by this panel were expressed in terms of 4 strata of resource levels: basic, limited, enhanced, and maximal. The current report describes the issues and questions related to HCS that are important to consider when designing, implementing, and measuring the performance of a BCP. Health ministers, other policymakers, healthcare personnel, administrators, and anyone else involved in developing a BCP can use and adapt this framework to improve outcomes and ensure the more effective use of resources.

    The concept of ubiquitous healthcare service, which emerged as one of measures to solve healthcare problems in aged society, means that patients can receive services such as prevention, diagnosis, therapy and prognosis management at any time and in any place with the help of advanced information and communication technology. This service requires not only biomedical digital assistant that can monitor continuously the patients' health condition regardless of time and place, but also wired and wireless communication devices and telemedicine servers that provide doctors with data on patients' present health condition. In order to implement a biomedical digital assistant that is portable and wearable to patients, the present study developed a device that minimizes size, weight and power consumption, measures ECG and PPG signals, and even monitors moving patients' state. The biomedical sensor with the function of wireless communication was designed to be highly portable and wearable, to be operable 24 hours with small-size batteries, and to monitor the subject's heart rate, step count and respiratory rate in his daily life. The biomedical signal receiving device was implemented in two forms, PDA and cellular phone. The movement monitoring device embedded in the battery pack of a cellular phone does not have any problem in operating 24 hours, but the real-time biomedical signal receiving device implemented with PDA operated up to 6 hours due to the limited battery capacity of PDA. This problem is expected to be solved by reducing wireless communication load through improving the processing and storage functions of the sensor. The developed device can transmit a message on the patient's emergency to the remote server through the cellular phone network, and is expected to play crucial roles in the health management of chronic-aged patients in their daily life.

    Consumer satisfaction with healthcare is an important quality and outcome indicator. Satisfaction may be at the crux of survival for healthcare delivery systems because it creates the competitive edge in healthcare. To better understand patient satisfaction by examining consumer healthcare experiences and expectations, a study was conducted. An important concept identified in the data, MY CARE, refers to a constellation of quality healthcare features that were wished for by all participants and realized by only some of them. The features of MY CARE offer lessons for all healthcare leaders to use when making improvements in care delivery systems-improvements that could create a more patient-centered healthcare system and boost patient satisfaction.

    Recent healthcare reform efforts in Mexico have focused on the need to improve the efficiency and equity of a fragmented healthcare system. In light of these reform initiatives, there is a need to assess whether healthcare subsystems are effective at providing high-quality healthcare to all Mexicans. Nationally representative household survey data from the 2006 Encuesta Nacional de Salud y Nutrición (National Health and Nutrition Survey) were used to assess perceived healthcare quality across different subsystems. Using a sample of 7234 survey respondents, we found evidence of substantial heterogeneity in healthcare quality assessments across healthcare subsystems favoring private providers over social security institutions. These differences across subsystems remained even after adjusting for socioeconomic, demographic, and health factors. Our analysis suggests that improvements in efficiency and equity can be achieved by assessing the factors that contribute to heterogeneity in quality across subsystems. PMID:19305224

    Picture Archiving and Communication System (PACS), which was originally designed as a tool for facilitating radiologists in interpreting images more efficiently, is evolving into a hospital-integrated system storing diagnostic imaging information that often reaches far beyond Radiology. The continuous evolution of PACS technology has led to a gradual broadening of its applications, ranging from teleradiology to CAD (Computer-Assisted Diagnosis) and multidimensional imaging, and is moving into the direction of providing access to image data outside the Radiology department, so to reach all the branches of the healthcare enterprise. New perspectives have been created thanks to new technologies (such as holographic media and GRID computing) that are likely due to expand PACS-based applications even further, improving patient care and enhancing overall productivity.

    This paper aims to assess consistent predictors through the use of a sample that includes different actors from the healthcare work force to identify certain key elements in a set of job-related organizational contexts. The utilized data were obtained from the 5th European Working Conditions Survey, conducted in 2010 by the European Foundation for the Improvement of Living and Working Conditions. In light of these objectives, we collected a subsample of 284 health professionals, some of them from the International Standard Classification of Occupations—subgroup 22—(ISCO-08). The results indicated that the chance of a healthcare worker referring to him/herself as bullied increases among those who work on a shift schedule, perform monotonous and rotating tasks, suffer from work stress, enjoy little satisfaction from their working conditions, and do not perceive opportunities for promotions in their organizations. The present work summarizes an array of outcomes and proposes within the usual course of events that workplace bullying could be reduced if job demands were limited and job resources were increased. The implications of these findings could assist human resource managers in facilitating, to some extent, good social relationships among healthcare workers. PMID:23887621

    It is desirable for a pharmaceutical final dosage form to be manufactured through a quality by design (QbD)-based approach rather than a quality by testing (QbT) approach. An automatic feedback control system coupled with PAT tools that is part of the QbD paradigm shift, has the potential to ensure that the pre-defined end product quality attributes are met in a time and cost efficient manner. In this work, an advanced hybrid MPC-PID control architecture coupled with real time inline/online monitoring tools and principal components analysis (PCA) based additional supervisory control layer has been proposed for a continuous direct compaction tablet manufacturing process. The advantages of both MPC and PID have been utilized in a hybrid scheme. The control hardware and software integration and implementation of the control system has been demonstrated using feeders and blending unit operation of a continuous tablet manufacturing pilot plant and an NIR based PAT tool. The advanced hybrid MPC-PID control scheme leads to enhanced control loop performance of the critical quality attributes in comparison to a regulatory (e.g. PID) control scheme indicating its potential to improve pharmaceutical product quality.

    Making decisions for a patient affected by sudden devastating illness or injury traumatizes a patient's family and loved ones. Even in the absence of an emergency, surrogates making end-of-life treatment decisions may experience negative emotional effects. Helping surrogates with these end-of-life decisions under emergent conditions requires the emergency physician (EP) to be clear, making medical recommendations with sensitivity. This model for emergency department (ED) end-of-life communications after acute devastating events comprises the following steps: 1) determine the patient's decision-making capacity; 2) identify the legal surrogate; 3) elicit patient values as expressed in completed advance directives; 4) determine patient/surrogate understanding of the life-limiting event and expectant treatment goals; 5) convey physician understanding of the event, including prognosis, treatment options, and recommendation; 6) share decisions regarding withdrawing or withholding of resuscitative efforts, using available resources and considering options for organ donation; and 7) revise treatment goals as needed. Emergency physicians should break bad news compassionately, yet sufficiently, so that surrogate and family understand both the gravity of the situation and the lack of long-term benefit of continued life-sustaining interventions. EPs should also help the surrogate and family understand that palliative care addresses comfort needs of the patient including adequate treatment for pain, dyspnea, or anxiety. Part I of this communications model reviews determination of decision-making capacity, surrogacy laws, and advance directives, including legal definitions and application of these steps; Part II (which will appear in a future issue of AEM) covers communication moving from resuscitative to end-of-life and palliative treatment. EPs should recognize acute devastating illness or injuries, when appropriate, as opportunities to initiate end-of-life discussions and to

    Environmental pollution is a recognized issue of major concern since a wide range of contaminants has been found in aquatic environment at ngL(-1) to μgL(-1) levels. In the year 2000, a strategy was defined to identify the priority substances concerning aquatic ecosystems, followed by the definition of environmental quality standards (EQS) in 2008. Recently it was launched the Directive 2013/39/EU that updates the water framework policy highlighting the need to develop new water treatment technologies to deal with such problem. This review summarizes the data published in the last decade regarding the application of advanced oxidation processes (AOPs) to treat priority compounds and certain other pollutants defined in this Directive, excluding the inorganic species (cadmium, lead, mercury, nickel and their derivatives). The Directive 2013/39/EU includes several pesticides (aldrin, dichlorodiphenyltrichloroethane, dicofol, dieldrin, endrin, endosulfan, isodrin, heptachlor, lindane, pentachlorophenol, chlorpyrifos, chlorfenvinphos, dichlorvos, atrazine, simazine, terbutryn, diuron, isoproturon, trifluralin, cypermethrin, alachlor), solvents (dichloromethane, dichloroethane, trichloromethane and carbon tetrachloride), perfluorooctane sulfonic acid and its derivatives (PFOS), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), nonylphenol and octylphenol, as well as the three compounds included in the recommendation for the first watch list of substances (diclofenac, 17-alpha-ethinylestradiol (EE2) and 17-beta-estradiol (E2)). Some particular pesticides (aclonifen, bifenox, cybutryne, quinoxyfen), organotin compounds (tributyltin), dioxins and dioxin-like compounds, brominated diphenylethers, hexabromocyclododecanes and di(2-ethylhexyl)phthalate are also defined in this Directive, but studies dealing with AOPs are missing. AOPs are recognized tools to destroy recalcitrant compounds or, at least, to transform them into biodegradable species

    Electronic Health Records (EHRs) play a crucial role in healthcare today. Considering a data-centric view, EHRs are very advanced as they provide and share healthcare data in a cross-institutional and patient-centered way adhering to high syntactic and semantic interoperability. However, the EHR functionalities available for the end users are rare and hence often limited to basic document query functions. Future EHR use necessitates the ability to let the users define their needed data according to a certain situation and how this data should be processed. Workflow and semantic modelling approaches as well as Web services provide means to fulfil such a goal. This thesis develops concepts for dynamic interfaces between EHR end users and a service oriented eHealth infrastructure, which allow the users to design their flexible EHR needs, modeled in a dynamic and formal way. These are used to discover, compose and execute the right Semantic Web services. PMID:27577496

  18. Balancing influence between actors in healthcare decision making

    PubMed Central

    2011-01-01

    Background Healthcare costs in most developed countries are not clearly linked to better patient and public health outcomes, but are rather associated with service delivery orientation. In the U.S. this has resulted in large variation in healthcare availability and use, increased cost, reduced employer participation in health insurance programs, and reduced overall population health outcomes. Recent U.S. healthcare reform legislation addresses only some of these issues. Other countries face similar healthcare issues. Discussion A major goal of healthcare is to enhance patient health outcomes. This objective is not realized in many countries because incentives and structures are currently not aligned for maximizing population health. The misalignment occurs because of the competing interests between "actors" in healthcare. In a simplified model these are individuals motivated to enhance their own health; enterprises (including a mix of nonprofit, for profit and government providers, payers, and suppliers, etc.) motivated by profit, political, organizational and other forces; and government which often acts in the conflicting roles of a healthcare payer and provider in addition to its role as the representative and protector of the people. An imbalance exists between the actors, due to the resources and information control of the enterprise and government actors relative to the individual and the public. Failure to use effective preventive interventions is perhaps the best example of the misalignment of incentives. We consider the current Pareto efficient balance between the actors in relation to the Pareto frontier, and show that a significant change in the healthcare market requires major changes in the utilities of the enterprise and government actors. Summary A variety of actions are necessary for maximizing population health within the constraints of available resources and the current balance between the actors. These actions include improved transparency of

    2014-01-01

    Smartphone-based devices and applications (SBDAs) with cost effectiveness and remote sensing are the most promising and effective means of delivering mobile healthcare (mHealthcare). Several SBDAs have been commercialized for the personalized monitoring and/or management of basic physiological parameters, such as blood pressure, weight, body analysis, pulse rate, electrocardiograph, blood glucose, blood glucose saturation, sleeping and physical activity. With advances in Bluetooth technology, software, cloud computing and remote sensing, SBDAs provide real-time on-site analysis and telemedicine opportunities in remote areas. This scenario is of utmost importance for developing countries, where the number of smartphone users is about 70% of 6.8 billion cell phone subscribers worldwide with limited access to basic healthcare service. The technology platform facilitates patient-doctor communication and the patients to effectively manage and keep track of their medical conditions. Besides tremendous healthcare cost savings, SBDAs are very critical for the monitoring and effective management of emerging epidemics and food contamination outbreaks. The next decade will witness pioneering advances and increasing applications of SBDAs in this exponentially growing field of mHealthcare. This article provides a critical review of commercial SBDAs that are being widely used for personalized healthcare monitoring and management. PMID:26852680
