Disaster Preparedness for Ebola Virus Disease: Perspective on National Public Health Policies and Case Study of North Carolina and UNC Hospital
Creators: name: Siddle, Jennica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The outbreak of Ebola virus disease (EVD) in West Africa from 2013 to 2015 illustrates the most recent example of the United States' growing need for domestic preparations for emerging infectious diseases. One case of Ebola presenting in the U.S. exposed weaknesses in federal and state level hospital preparations, employee protections, and screening, prevention, and surveillance protocols. In disaster preparedness federal entities such as the Centers for Disease Control (CDC) and key leaders of health care organizations are expected to strike a balance between disseminating timely information to train and protect workers and patients with appropriate resource utilization; a difficult task especially in the current national health care climate that demands value and cost effectiveness. Around the nation hospitals took various approaches for Ebola preparedness, often in a non-systematic or un-regulated manner. Late in the Ebola outbreak, regional tiered response systems called Ebola Treatment Facilities or Centers (hereafter called ETFs) were introduced as a federal policy for the emergency response. This study used interviews with key decision makers or stakeholders from the UNC Health Care System (Chapel Hill, NC) and the Public Health Department of North Carolina to identify key themes in system leaders' thinking about Ebola preparation and also about the opportunity to pursue ETF status. Stakeholders emphasized that the experience of preparing for Ebola was expensive but protecting the public and employees was a priority worth the resources it cost. Ultimately, leaders in North Carolina declined ETF status mostly due to lack of federal planning around the designation and lack of funding at the time. ETF designation did not roll out clearly and went relatively untested as the outbreak overseas declined and screening domestically increased. A triangulation of careful review of the policy documents, interviews with key stakeholders, a survey of health care workers, and a limited systematic review of the literature permits me to conclude that capitalizing on national and local Ebola preparations will require that future federal disease preparedness policy better define the regionalized approach and strengthen local collaboration; promote ongoing training and adaptable communicable disease plans; and provide more and more consistently distributed funding for public health infrastructure and hospital preparedness programs.

description: Using an exact numerical solution and semiclassical analysis, we investigate quantum oscillations (QOs) in a model of a bilayer system with an anisotropic (elliptical) electron pocket in each plane. Key features of QO experiments in the high temperature superconducting cuprate YBCO can be reproduced by such a model, in particular the pattern of oscillation frequencies (which reflect "magnetic breakdown" between the two pockets) and the polar and azimuthal angular dependence of the oscillation amplitudes. However, the requisite magnetic breakdown is possible only under the assumption that the horizontal mirror plane symmetry is spontaneously broken and that the bilayer tunneling, $t_\perp$, is substantially renormalized from its `bare' value. Under the assumption that $t_\perp= \tilde{Z}t_\perp^{(0)}$, where $\tilde{Z}$ is a measure of the quasiparticle weight, this suggests that $\tilde{Z} \lesssim 1/20$. Detailed comparisons with new YBa$_2$Cu$_3$O$_{6.58}$ QO data, taken over a very broad range of magnetic field, confirm specific predictions made by the breakdown scenario.

Analysis of NeuroEyeCoach data

Publisher: name: Open Science Framework
Year: 2022

description: NeuroEyeCoach (NEC) is a rehabilitation intervention programme aimed at those with visual field defects as a result of brain trauma, stroke, other insults or surgical procedures. It alleviates the disability associated with visual field defect by improving the patient’s visual scanning technique. Smaller studies using similar stimulus configurations have shown success of eye-movement therapy on visual search performance metrics, such as shorter search times and less detection errors (Zihl 1985; Meienberg et al., 1981; Zihl & Hebel 1997). To evaluate the effect of rehabilitation on patient’s activities of daily life, a questionnaire is often used where the patient self-reports their experience of disability on 10 aspects of daily life on a 5 point Likert-scale (Nelles et al 2001). NEC therefore includes visual search tasks and a disability questionnaire pre and post intervention to evaluate outcome. NEC is delivered through an online programme, adaptive to the patient’s visual disability and self-administered at home or in a clinical setting (Sahraie et al., 2016). NEC was developed by NovaVision Inc. (Boca Raton, Florida), is registered with the FDA as 510(k) exempt medical device in the US and CE registered as Type I Medical Device in the EU; and. Over 200 participants have completed NEC to-date.
Prevention of Unintended Adolescent Pregnancies Through Greater Access to Long Acting Reversible Contraceptives
Creators: name: Watson, Autumn

Year: 2016

description: Adolescent pregnancies have negative implications not only for the teen parent but also for society making unintended teen pregnancies an important public health issue. In the United States (US) adolescent females aged 15-19 years old had a birth rate of 24.2 births per 1000 women in the year 2014 (Romero, et al, 2015). Subsequently, women who enter into motherhood as teens have significantly lower high school graduation rates and higher rates of poverty. Only 50% of adolescent mothers receive a high school diploma compared to over 90% of adolescent girls who are not mothers (Centers for Disease Control and Prevention [CDC], 2015). A sordid history has caused long-acting reversible contraceptives (LARCs) to traditionally not be marketed to adolescents. Although almost half of US adolescents aged 15-19 are sexually active, less than 5% of adolescent’s report using a LARC (American College of Obstetricians and Gynecologists [ACOG], 2012). As of 2014, the ACOG and the American Academy of Pediatrics (AAP) recommend LARCs for all women of childbearing age as the most effective form of birth control to prevent unintended pregnancies. Despite these recommendations, adolescents continue to face barriers when attempting to obtain a LARC as a method of contraception. Lack of youth-friendly services, cost, provider perception of LARC use in adolescents, and gaps in LARC insertion and removal training, prevent adolescents from choosing to take advantage of a LARC to prevent unintended pregnancies (ACOG, 2012). This paper undertakes a review of policy regarding adolescents access, education and utilization of LARCs and presents recommendations for policy changes and other approaches based on established research methods to eliminate barriers facing adolescents in their reproductive choices.

Our approach combines the advantages of the different methods allowing for a fast evaluation of the amplitude while monitoring the numerical stability of the calculation. In phase space regions close to singular kinematics we use a method avoiding spurious Gram determinants in the calculation. As an application of our approach we report on the status of the calculation of the amplitude for the process $pp\to b\bar{b}b\bar{b}+X$.

The Role of Federally Qualified Health Centers in Serving the Underserved: Understanding the Past to Navigate the Future
Creators: name: Brown, Tanilla Louise
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Federally Qualified Health Centers (FQHCs) have provided over 40 years of continuous service to the poorest patient populations in the country. Born out of the strongly democratic ideals of the civil rights movement of the 60s, they have continued to emphasize patient-centered care despite the ever-changing political landscape around them. FQHCs have demonstrated positive outcomes and effectiveness in their communities that gradually gained them faithful bipartisan support and advocates. One supporter was President George W. Bush. This paper reviews the Bush Administration expansion of FQHCs, the largest in their history. The study explores important motivators driving this rapid expansion and investigates the political and functional effect the expansion had on community health centers. METHODS: We used systematic literature review, review of Congressional documents, and structured interviews of elite stakeholders as the key data sources for this study. CONCLUSIONS: Many motivators lead to the legislative decision to expand federally qualified community health centers including convincing data of their effectiveness, demonstrated cost-efficiency, sense of urgency in the face of the worsening health care crisis, and a desire to avoid more drastic system-wide change. Ultimately, FQHCs continue to function well in the post-expansion era, however, many gaps in service delivery remain. RECOMMENDATIONS: Safety net expansion alone cannot adequately address growing health care needs in this country. However, FQHCs are an important part of the safety net and should be protected and preserved as we move incrementally towards more systemic change.

description: We present a comprehensive study of Far Ultraviolet Spectroscopic Explorer (FUSE) spectra (912-1190 A) of two members of the PG1159 spectral class, which consists of hydrogen-deficient (pre-) white dwarfs with effective temperatures in the range Teff = 75,000-200,000 K. As two representatives of the cooler objects, we have selected PG1707+427 (Teff = 85,000 K) and PG1424+535 (Teff = 110,000 K), complementing a previous study of the hotter prototype PG1159-035 (Teff = 140,000 K). The helium-dominated atmospheres are strongly enriched in carbon and oxygen, therefore, their spectra are dominated by lines from C III-IV and O III-VI, many of which were never observed before in hot stars. In addition, lines of many other metals (N, F, Ne, Si, P, S, Ar, Fe) are detectable, demonstrating that observations in this spectral region are most rewarding when compared to the near-ultraviolet and optical wavelength bands. We perform abundance analyses of these species and derive upper limits for several undetected light and heavy metals including iron-group and trans-iron elements. The results are compared to predictions of stellar evolution models for neutron-capture nucleosynthesis and good agreement is found.

description: After a brief historical review of ergodicity and mixing in dynamics, particularly in quantum dynamics, we introduce definitions of quantum ergodicity and mixing using the structure of the system's energy levels and spacings. Our definitions are consistent with usual understanding of ergodicity and mixing. Two parameters concerning the degeneracy in energy levels and spacings are introduced. They are computed for right triangular billiards and the results indicate a very close relation between quantum ergodicity (mixing) and quantum chaos. At the end, we argue that, besides ergodicity and mixing, there may exist a third class of quantum dynamics which is characterized by a maximized entropy.

The Limits of Accountability: A Prospective Policy Analysis of Accountable Care Organizations
Creators: name: Yeatts, John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: In a short period of time policymakers have propelled accountability from theory to practice in the form of the Accountable Care Organization (ACO). A mixed model of delivery and payment reform, the ACO is theorized to curb Medicare spending by incentivizing groups of physicians and other caregivers to provide coordinated and high quality care across diverse health care settings. Although ACOs are unlikely to cure all that ails America’s health system, results from ACO-like experiments such as the Physician Group Practice Demonstration (PGPD) have fueled policymakers’ hopes that ACOs will produce significant cost savings. Although the definitive structure of ACOs has yet to be resolved, a provisional rule recently proposed by the Centers for Medicare and Medicaid Services (CMS) offers a glimpse of their likely form. The ACO model is appealing in theory, but the current proposal for implementation suggests that ACOs may fail to yield significant cost savings to Medicare. If implemented as currently elaborated, ACOs may be limited by weak financial incentives and low participation among physicians. Of particular concern is the lack of meaningful payment reform. The current proposal suggests ACOs will do little to disrupt the prevailing incentive structure embedded in the Medicare Fee Schedule (MFS). The purpose of this paper is to explore the limitations of CMS’ current proposal and how these limitations may constrain projected cost savings. This paper will also propose alternatives that may better promote the ideals of ACOs while ensuring that significant cost savings are achieved.
Hilbert von Neumann Modules versus Concrete von Neumann Modules

Subjects: subject: Operator Algebras (math.OA)

subject: 46L07

description: Apart from presenting some new insights and results, one of our main purposes is to put some records in the development of von Neumann modules straight. The von Neumann or $W^*$-objects among the Hilbert ($C^*$-)modules are around since the first papers by Paschke (1973) and Rieffel (1974) that lift Kaplansky's setting (1953) to modules over noncommutative $C^*$-algebras. While the formal definition of $W^*$-modules} is due to Baillet, Denizeau, and Havet (1988), the one of von Neumann modules as strongly closed operator spaces started with Skeide (2000). It has been paired with the definition of concrete von Neumann modules in Skeide (2006). It is well-known that (pre-)Hilbert modules can be viewed as ternary rings of operators and in their definition of Hilbert-von Neumann modules, Bikram, Mukherjee, Srinivasan, and Sunder (2012) take that point of view. We illustrate that a (suitably nondegenerate) Hilbert-von Neumann module is the same thing as a strongly full concrete von Neumann module. We also use this occasion to put some things in earlier papers right. We show that the tensor product of (concrete, or not) von Neumann correspondences is, indeed, (a generalization of) the tensor product of Connes correspondences (claimed in Skeide (2008)), viewed in a way quite different from Bikram et al.. We also present some new arguments that are useful even for (pre-)Hilbert modules.

Patient Characteristics Associated with Return Visits to a Pediatric Emergency Department

Year: 2008

description: Title: Patient Characteristics Associated with Return Visits to a Pediatric Emergency Department Author: Hallam Gugelmann Objectives: The primary objective of this study is to identify and quantify the patient characteristics associated with 72-hour pediatric return visits to a tertiary care center’s emergency department. The hypothesis was that 72-hour return visits would be increased in patients with public insurance or no health insurance when compared to those individuals with private insurance. Methods In order to attain the study’s state objectives, the principal investigator of this study undertook a retrospective review of the hospital’s centralized billing database, specifying only the date range (1/1/2005 through 12/1/2007) and the age range (birth through 18 years of age) in the data extraction request. Data were collated by medical record number and date of visit, and time differences between each visit were calculated in order to identify all 72-hour return visits. Statistical analyses were then conducted, using Microsoft Excel to collate data and Stata version10.0 to perform logistic regression analyses. Results Out of a total of 39,481 recorded patient visits, 1,392 (3.5% of all pediatric visits) were 72-hour return visits. The primary variable of insurance type was not related to the outcome of 72-hour return visit in a statistically significant manner. Of additional variables analyzed, race, age, distance to the emergency department, weekly and annual timing of visits, visit acuity and post-assessment disposition were all significantly correlated to the outcome of 72-hour return visit, as assessed by logistic regression. Conclusions Although long thought to be a predictor of emergency department utilization and 72-hour return visits, insurance status does not appear to determine 72-hour return visits in a statistically significant manner. The additional variables of race and seasonal timing of visits, however, were found to relate to the outcome of 72- hour return visit in a statistically significant manner. Research is needed to further substantiate this relationship at other institutions and to identify means of addressing disparities in emergency department use among pediatric patients.

description: Linear regression models depend directly on the design matrix and its properties. Techniques that efficiently estimate model coefficients by partitioning rows of the design matrix are increasingly popular for large-scale problems because they fit well with modern parallel computing architectures. We propose a simple measure of {\em concordance} between a design matrix and a subset of its rows that estimates how well a subset captures the variance-covariance structure of a larger data set. We illustrate the use of this measure in a heuristic method for selecting row partition sizes that balance statistical and computational efficiency goals in real-world problems.

description: Two-dimensional AKLT model on a honeycomb lattice has been shown to be a universal resource for quantum computation. In this valence bond solid, however, the spin interactions involve higher powers of the Heisenberg coupling $(\vec{S}_i \cdot \vec{S}_j)^n$, making these states seemingly unrealistic on bipartite lattices, where one expects a simple antiferromagnetic order. We show that those interactions can be generated by orbital physics in multiorbital Mott insulators. We focus on $t_{2g}$ electrons on the honeycomb lattice and propose a physical realization of the spin-$3/2$ AKLT state. We find a phase transition from the AKLT to the Neel state on increasing Hund's rule coupling, which is confirmed by density matrix renormalization group (DMRG) simulations. An experimental signature of the AKLT state consists of protected, free spins-1/2 on lattice vacancies, which may be detected in the spin susceptibility.

description: The prospects are explored for testing Lorentz and CPT symmetry in the top-quark sector. We present the relevant Lagrange density, discuss physical observables, and describe the signals to be sought in experiments. For top-antitop pair production via quark or gluon fusion with subsequent semileptonic or hadronic decays, we obtain the matrix element in the presence of Lorentz violation using the narrow-width approximation. The issue of testing CPT symmetry in the top-quark sector is also addressed. We demonstrate that single-top production and decay is well suited to a search for CPT violation, and we present the matrix elements for single-top production in each of the four tree-level channels. Our results are applicable to searches for Lorentz violation and studies of CPT symmetry in collider experiments, including notably high-statistics top-antitop and single-top production at the Large Hadron Collider.

Lessons Learned From Two Social Marketing HIV Prevention Interventions
Creators: name: Singzon, Trudy K., MD
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: HIV/AIDS continues to be a problem in the United States and the epidemic continues to change. As the incidence of HIV decreases in some populations as a result of awareness and testing campaigns, the rate of infection has been increasing in others. Despite the fact that we have learned much about the transmission of HIV and important risk factors such as unprotected sexual intercourse are known, the disease continues to affect hundreds of thousands in the U.S. alone. Since the early days of the epidemic, HIV prevention efforts have seen modest results. Behavior is difficult to change and we have learned that mere dissemination of information is not adequate to change behavior. New challenges to HIV prevention efforts have been encountered as the epidemic shifts to high-risk populations that are frequently poor, marginalized, and thus, difficult to reach with traditional public health interventions. Thus, we need to come up with new and creative ways to reach high-risk populations since traditional methods and messages do not appear to be effective. In this paper, I critique social marketing as a possible solution to creating effective HIV prevention interventions targeted to high-risk U.S. populations. The purpose of this paper is to investigate the lessons learned from HIV prevention interventions in the U.S. that used social marketing approaches.

description: Afivo is a framework for simulations with adaptive mesh refinement (AMR) on quadtree (2D) and octree (3D) grids. The framework comes with a geometric multigrid solver, shared-memory (OpenMP) parallelism and it supports output in Silo and VTK file formats. Afivo can be used to efficiently simulate AMR problems with up to about $10^{8}$ unknowns on desktops, workstations or single compute nodes. For larger problems, existing distributed-memory frameworks are better suited. The framework has no built-in functionality for specific physics applications, so users have to implement their own numerical methods. The included multigrid solver can be used to efficiently solve elliptic partial differential equations such as Poisson's equation. Afivo's design was kept simple, which in combination with the shared-memory parallelism facilitates modification and experimentation with AMR algorithms. The framework was already used to perform 3D simulations of streamer discharges, which required tens of millions of cells.

description: The rapid neutron-capture process (r-process) is a major process to synthesize elements heavier than iron, but the astrophysical site(s) of r-process is not identified yet. Neutron star mergers (NSMs) are suggested to be a major r-process site from nucleosynthesis studies. Previous chemical evolution studies however require unlikely short merger time of NSMs to reproduce the observed large star-to-star scatters in the abundance ratios of r-process elements relative to iron, [Eu/Fe], of extremely metal-poor stars in the Milky Way (MW) halo. This problem can be solved by considering chemical evolution in dwarf spheroidal galaxies (dSphs) which would be building blocks of the MW and have lower star formation efficiencies than the MW halo. We demonstrate that enrichment of r-process elements in dSphs by NSMs using an N-body/smoothed particle hydrodynamics code. Our high-resolution model reproduces the observed [Eu/Fe] by NSMs with a merger time of 100 Myr when the effect of metal mixing is taken into account. This is because metallicity is not correlated with time up to ~ 300 Myr from the start of the simulation due to low star formation efficiency in dSphs. We also confirm that this model is consistent with observed properties of dSphs such as radial profiles and metallicity distribution. The merger time and the Galactic rate of NSMs are suggested to be

description: Magnons are the energy quanta of fundamental spin excitations, namely spin waves, and they can make a considerable contribution to energy transport in some magnetic materials in a similar manner as lattice vibration waves or phonons. The coupling and possible non-equilibrium between magnons and other energy carriers have been used to explain several recently discovered thermally driven spin transport and energy conversion phenomena. Here, we report experiments in which local non-equilibrium between magnons and phonons in a single crystalline bulk magnetic insulator, Y3Fe5O12 (yttrium iron garnet, or YIG), has been created optically within a focused laser spot and probed directly with the use of micro-Brillouin light scattering (BLS). By analyzing the experimental results with a thermally induced magnon diffusion model, we obtain the magnon diffusion length of thermal magnons. By explicitly establishing non-equilibrium between magnons and phonons, our studies represent an important step toward a quantitative understanding of various spin-heat coupling phenomena.

description: A consistent interpretation of the Higgs data requires the same precision in the Higgs boson masses and in the trilinear Higgs self-couplings, which are related through their common origin from the Higgs potential. In this work we provide the two-loop corrections at order ${\cal O}(α_t α_s)$ in the approximation of vanishing external momenta to the trilinear Higgs self-couplings in the CP-violating Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM). In the top/stop sector two different renormalization schemes have been implemented, the OS and the $\overline{\text{DR}}$ scheme. The two-loop corrections to the self-couplings are of the order of 10\% in the investigated scenarios. The theoretical error, estimated both from the variation of the renormalization scale and from the change of the top/stop sector renormalization scheme, has been shown to be reduced due to the inclusion of the two-loop corrections.

Incidence, Mortality and Cervical Cancer Prevention Strategies in South America

description: Cervical cancer is caused by persistent infection with certain genotypes of human papillomavirus (HPV). It is a significant public health problem among women in South America where some of the highest incidence rates in the world are observed. The International Agency for Research on Cancer (IARC) estimates the crude incidence and mortality of cervical cancer in South America to be 24.6 and 11.2 per 100,000 women respectively (IARC 2008). Both incidence and mortality are approximately two times higher than the rates in developed countries such as the United States. Also contributing to the seriousness of this problem is the fact that epidemiological studies suggest that incidence and mortality from cervical cancer are projected to increase in South America by 2020 (Agurto, Bishop, Sanchez, Betancourt & Robles 2004). The purpose of this paper is to review the most current available information on cervical cancer in South American countries and summarize the methods and performance of existing screening programs. This information will be used to identify promising strategies, such as new screening methods and HPV vaccination, that are being researched or utilized in other low resource settings and could potentially be implemented in South America. Data were collected by performing a MEDLINE search of papers published from January 2000 through December 2010. This research documented the high prevalence of HPV infection and a lack of well-organized screening programs, which are responsible for the high burden of cervical cancer in South America. It also documented the absence or poor quality of information and surveillance systems in most South American countries, which makes collection of data, patient follow-up, and program monitoring and evaluation difficult. Also important, some variation in these patterns was observed among South American countries. For example, though both could be improved upon, the screening programs in Chile and Colombia have resulted in modest reductions in incidence and/or mortality and can serve as a model for the rest of South America. This research has led to the following recommendations to reduce cervical cancer incidence and mortality in South America. South American countries with screening programs already in place should continue to support screening, though revisions will be necessary. In countries without screening programs, it is advised that policy makers consider initiating a screening program for women at high risk of cervical cancer. In both instances, it is recommended that screening occur in conjunction with vaccination of adolescent girls and women who are not yet sexually active. Policy makers are urged to seek out resources to carry out all of the above, including maximizing the use of vaccine subsidies that are available.

description: We show that ideal submodules and closed ternary ideals in Hilbert modules are the same. We use this insight as a little peg on which to hang a little note about interrelations with other notions regarding Hilbert modules. In Section 3, we show that the ternary ideals (and equivalent notions) merit fully, in terms of homomorphisms and quotients, to be called ideals of (not necessarily full) Hilbert modules. The properties to be checked are intrinsically formulated for the modules (without any reference to the algebra over which they are modules) in terms of their ternary structure. The proofs, instead, are motivated from a third equivalent notion, linking ideals (Section 2), and a Theorem (Section 3) that all extends nicely to (reduced) linking algebras. As an application, in Section 4, we introduce ternary extensions of Hilbert modules and prove most of the basic properties (some new even for the known notion of extensions of Hilbert modules), by reducing their proof to the well-known analogue theorems about extensions of $C^*$-algebras. Finally, in Section 5, we propose several open problems that our method naturally suggests.

description: We present far-infrared spectral line observations of five galaxies from the LITTLE THINGS sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to observational constraints, our data extend the observed parameter space into the regime of low surface brightness dwarf galaxies with low metallicities and moderate star formation rates. Our targets were observed with Herschel at the [CII] 158um, [OI] 63um, [OIII] 88um, and NII 122um emission lines using the PACS Spectrometer. These high-resolution maps allow us for the first time to study the far-infrared properties of these systems on the scales of larger star-forming complexes. The spatial resolution in our maps, in combination with star formation tracers, allows us to identify separate PDRs in some of the regions we observed. Our systems have widespread [CII] emission that is bright relative to continuum, averaging near 0.5% of the total infrared budget - higher than in solar-metallicity galaxies of other types. [NII] is weak, suggesting that the [CII] emission in our galaxies comes mostly from PDRs instead of the diffuse ionized ISM. These systems exhibit efficient cooling at low dust temperatures, as shown by ([OI]+[CII])/TIR in relation to 60um/100um, and low [OI]/[CII] ratios which indicate that [CII] is the dominant coolant of the ISM. We observe [OIII]/[CII] ratios in our galaxies that are lower than those published for other dwarfs, but similar to levels noted in spirals.

Effectiveness of Medical Ethics Education: A Review of the Literature
Creators: name: Palwai, Aishwarya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Medical ethics education is a required part of the curriculum in every medical school in the United States today. Courses in medical ethics have also been introduced in the curricula of all medical schools in Canada and in most school in United Kingdom and around the world. The World Federation for Medical Education in 1994 (at the World Summit of Medical Education) released a consensus statement that ethics should always receive full attention in the medical school, in all clinical encounters, and in the community. There is a wide disparity between the perceived need for education in medical ethics and the actual implementation of such programs. It is possible that this is, in part, because formal medical ethics education is a relatively infant field, especially so at the graduate medical education level. An inherent paradox in this situation is that only after reaching consensus on what should be taught can medical ethics educators go on to study whether such teaching has resulted in positive outcomes. Enough interest to ensure discussion and consensus about this cannot be achieved until the field is evaluated sufficiently to claim the validity required for universal implementation. On the flip side, it has been argued that it is not necessary to demonstrate an effect of ethics education for medical students or residents in order to justify teaching ethics, and that ethics should be part of the basic curriculum along with the other core medical subjects. Evaluation of the effectiveness of various methods of training in medical ethics takes on a critical role in today's academic environment because of the background considerations of cost and outcomes as measures of the value of the education. Such evaluations would ideally test improvement in ethical behaviors of the study subjects. But the constraints of reality dictate that less tangible and easily measurable aspects of the training such as knowledge base or confidence of the study subjects are usually tested. This is a major concern when trying to decide whether an education intervention is effective or not. This paper reviews the literature on the evaluation of ethics training in medical schools, residency programs and among practicing physicians, in the USA and abroad. It distinguishes the variable definitions of the terms 'medical ethics education' and 'effectiveness', provides a history of ethics education, and provides a context for the need for medical ethics education. This is followed by a review and analysis of the relevant literature, a discussion of the findings and the ensuing conclusions.
