Lessons Learned from Implementing the Patient-Centered Medical Home
Ellen P. Green,John Wendland,M. Colette Carver,Cortney Hughes Rinker,Seong K. Mun
International Journal of Telemedicine and Applications , 2012, DOI: 10.1155/2012/103685
Abstract: The Patient-Centered Medical Home (PCMH) is a primary care model that provides coordinated and comprehensive care to patients to improve health outcomes. This paper addresses practical issues that arise when transitioning a traditional primary care practice into a PCMH recognized by the National Committee for Quality Assurance (NCQA). Individual organizations' experiences with this transition were gathered at a PCMH workshop in Alexandria, Virginia in June 2010. An analysis of their experiences has been used along with a literature review to reveal common challenges that must be addressed in ways that are responsive to the practice and patients’ needs. These are: NCQA guidance, promoting provider buy-in, leveraging electronic medical records, changing office culture, and realigning workspace in the practice to accommodate services needed to carry out the intent of PCMH. The NCQA provides a set of standards for implementing the PCMH model, but these standards lack many specifics that will be relied on in location situations. While many researchers and providers have made critiques, we see this vagueness as allowing for greater flexibility in how a practice implements PCMH. 1. Introduction In response to the increasing demand for an improved healthcare system in the United States, the American Academy of Family Physicians, the American Academy of Pediatrics, the American College of Physicians, and the American Osteopathic Association developed the Joint Principles of the Patient-Centered Medical Home (Table 1 [1]) [2]. The Patient-Centered Medical Home (PCMH) is an extension of internationally employed Edward Wagner’s Chronic Care Model (CCM). The CCM was developed to address the increasing rate of patients with chronic conditions in the United States using team-based care. The rate of chronic conditions is currently estimated to be 2.2 conditions for individuals having 60 years old and up, on average [3]. In its implementation, the CCM has proven to reduce patients’ healthcare costs and improve patient care quality, two elements directly aligned with the goals of the PCMH [3]. The PCMH model strives to provide quality, coordinated, and cost-effective care to patients and to increase access to services. In addition, it aims to increase practice efficiency and subsequently provider and patient satisfaction. Within this paper, we follow the process of implementing the PCMH Model within primary care practices and discuss the difficulties these practices have encountered in the transition as well as potential solutions. Our goal is to provide future PCMHs
Work-Based Learning in Rural America: Employer Participation in School-to-Work Programs and Apprenticeships
Green, G. P.
Journal of Research in Rural Education , 2005,
Abstract: Since the 1980s, many states have initiated institutional reforms designed to address perceived deficiencies in traditional schooling. Most of these reforms involve stronger linkages between employers and schools. In this article, I examine the factors influencing employer involvement in school-to-work programs and apprenticeships in rural America. Data are drawn from a telephone survey of a stratified random sample of 1,590 employers in nonmetropolitan areas of the U.S. Firm size is the strongest factor influencing employer involvement in school-to-work programs. Employers expressing difficulty in recruiting workers are more likely to be involved in school-to-work programs. There is considerable regional variation in employer involvement, with firms in the West and Midwest more likely to be engaged in these activities. Large firms in the manufacturing sector are most likely to be offering apprenticeships.
Dissecting the risky-choice framing effect
Ellen Peters,Irwin P. Levin
Judgment and Decision Making , 2008,
Abstract: Using five variants of the Asian Disease Problem, we dissected the risky-choice framing effect by requiring each participant to provide preference ratings for the full decision problem and also to provide attractiveness ratings for each of the component parts, i.e., the sure-thing option and the risky option. Consistent with previous research, more risky choices were made by respondents receiving negatively framed versions of the decision problems than by those receiving positively framed versions. However, different processes were evident for those scoring high and low on numeracy. Whereas the choices of the less numerate showed a large effect of frame above and beyond any influence of their evaluations of the separate options, the choices of the highly numerate were almost completely accounted for by their attractiveness ratings of the separate options. These results are consistent with an increased tendency of the highly numerate to integrate complex numeric information in the construction of their preferences and a tendency for the less numerate to respond more superficially to non-numeric sources of information.
An interquark potential model for multi-quark systems
A. M. Green,P. Pennanen
Physics , 1998, DOI: 10.1103/PhysRevC.57.3384
Abstract: A potential model for four interacting quarks is constructed in SU(2) from six basis states -- the three partitions into quark pairs, where the gluon field is either in its ground state or first excited state. With four independent parameters to describe the interactions connecting these basis states, it is possible to fit 100 pieces of data -- the ground and first excited states of configurations from six different four-quark geometries calculated on a 16^3*32 lattice.
Nonequilibrium Noise in Metals at Mesoscopic Scales
F. Green,M. P. Das
Physics , 1997,
Abstract: We review a semiclassical theory of high-field noise in degenerate conductors, based on propagator solutions to the Boltzmann equation for the fluctuation distribution function. The theory provides a microscopic description of correlation-induced suppression of noise in quantum-confined systems, such as heterojunction devices. It is also capable of describing diffusive conductors in the mesoscopic regime. We discuss nonequilibrium thermal noise in a simple model of a mesoscopic wire.
A model for multi-quark systems
A. M. Green,P. Pennanen
Physics , 1997, DOI: 10.1016/S0370-2693(98)00300-1
Abstract: As a step towards understanding multi-quark systems abundant in nature we construct a model that reproduces the binding energies of static four-quark systems. These energies have been calculated using SU(2) lattice gauge theory for a set of six different geometries representative of the general case. The model is based on ground and excited state two-body potentials and multi-quark interaction terms.
The Landauer Formula: a Magic Mantra Revisited
Mukunda P. Das,Frederick Green
Physics , 2003,
Abstract: We review the conceptual structure of the Landauer theory of electron transport in the light of quantum kinetics, the orthodox framework for describing conductance at all scales. In a straightforward analysis, we assess popular claims for a rational link between Landauer theory on the one hand, and orthodox microscopics on the other. The need to explicitly include inelastic (dissipative) carrier relaxation is key to any well-posed microscopic model of open-system mesoscopic transport.
Mesoscopic transport revisited
Mukunda P. Das,Frederick Green
Physics , 2009, DOI: 10.1088/0953-8984/21/10/101001
Abstract: Having driven a large part of the decade's progress in physics, nanoelectronics is now passing from today's realm of the extraordinary to tomorrow's commonplace. This carries the problem of turning proofs of concept into practical artefacts. Better and more sharply focussed predictive modelling will be the ultimate guide to optimising mesoscopic technology as it matures. Securing this level of understanding needs a reassessment of the assumptions at the base of the present state of the field. We offer a brief overview of the underlying assumptions of mesoscopic transport.
Nonequilibrium mesoscopic transport: a genealogy
Mukunda P. Das,Frederick Green
Physics , 2012, DOI: 10.1088/0953-8984/24/18/183201
Abstract: Models of nonequilibrium quantum transport underpin all modern electronic devices, from the largest scales to the smallest. Past simplifications such as coarse graining and bulk self-averaging served well to understand electronic materials. Such particular notions become inapplicable at mesoscopic dimensions, edging towards the truly quantum regime. Nevertheless a unifying thread continues to run through transport physics, animating the design of small-scale electronic technology: microscopic conservation and nonequilibrium dissipation. These fundamentals are inherent in quantum transport and gain even greater and more explicit experimental meaning in the passage to atomic-sized devices. We review their genesis, their theoretical context, and their governing role in the electronic response of meso- and nanoscopic systems.
Comments on "Ohm's Law Survives to the Atomic Scale" by Weber et al
Mukunda P. Das,Frederick Green
Physics , 2012,
Abstract: The recent article "Ohm's Law Survives to the Atomic Scale" by Weber et al. [Science 335, 64 (1021)] reveals ohmic transport in quantized P-in-Si wires. We argue that their results have two main deficiencies: (a) the interpretation of conductance data is inadequate for serious systematics; (b) metallic-like structures hold few implications for quantum computing.
