    Orthogonal frequency division multiple access (OFDMA), which is widely used in the wireless sensor networks, allows different users to obtain different subcarriers according to their subchannel gains. Therefore, how to assign subcarriers and power to different users to achieve a high system sum rate is an important research area in OFDMA systems. In this paper, the focus of study is on the rate adaptive (RA) based resource allocation with proportional fairness constraints. Since the resource allocation is a NP-hard and non-convex optimization problem, a new efficient resource allocation algorithm ACO-SPA is proposed, which combines ant colony optimization (ACO) and suboptimal power allocation (SPA). To reduce the computational complexity, the optimization problem of resource allocation in OFDMA systems is separated into two steps. For the first one, the ant colony optimization algorithm is performed to solve the subcarrier allocation. Then, the suboptimal power allocation algorithm is developed with strict proportional fairness, and the algorithm is based on the principle that the sums of power and the reciprocal of channel-to-noise ratio for each user in different subchannels are equal. To support it, plenty of simulation results are presented. In contrast with root-finding and linear methods, the proposed method provides better performance in solving the proportional resource allocation problem in OFDMA systems. PMID:26426016

    With rapid growth of Internet applications, supporting differentiated service and enlarging system capacity have been new tasks for next generation access system. In recent years, research in OFDMA Passive Optical Networks (PON) has experienced extraordinary development as for its large capacity and flexibility in scheduling. Although much work has been done to solve hardware layer obstacles for OFDMA PON, scheduling algorithm on OFDMA PON system is still under primary discussion. In order to support QoS service on OFDMA PON system, a novel dynamic wavelength bandwidth allocation (DWBA) algorithm is proposed in this paper. Per-stream QoS service is supported in this algorithm. Through simulation, we proved our bandwidth allocation algorithm performs better in bandwidth utilization and differentiate service support.

  4. Adaptive Subframe Partitioning and Efficient Packet Scheduling in OFDMA Cellular System with Fixed Decode-and-Forward Relays

    NASA Astrophysics Data System (ADS)

    Wang, Liping; Ji, Yusheng; Liu, Fuqiang

    The integration of multihop relays with orthogonal frequency-division multiple access (OFDMA) cellular infrastructures can meet the growing demands for better coverage and higher throughput. Resource allocation in the OFDMA two-hop relay system is more complex than that in the conventional single-hop OFDMA system. With time division between transmissions from the base station (BS) and those from relay stations (RSs), fixed partitioning of the BS subframe and RS subframes can not adapt to various traffic demands. Moreover, single-hop scheduling algorithms can not be used directly in the two-hop system. Therefore, we propose a semi-distributed algorithm called ASP to adjust the length of every subframe adaptively, and suggest two ways to extend single-hop scheduling algorithms into multihop scenarios: link-based and end-to-end approaches. Simulation results indicate that the ASP algorithm increases system utilization and fairness. The max carrier-to-interference ratio (Max C/I) and proportional fairness (PF) scheduling algorithms extended using the end-to-end approach obtain higher throughput than those using the link-based approach, but at the expense of more overhead for information exchange between the BS and RSs. The resource allocation scheme using ASP and end-to-end PF scheduling achieves a tradeoff between system throughput maximization and fairness.

    A Novel technique for reducing the OBI noise in optical OFDMA-PON uplink is presented. OFDMA is a multipleaccess/ multiplexing scheme that can provide multiplexing operation of user data streams onto the downlink sub-channels and uplink multiple access by means of dividing OFDM subcarriers as sub-channels. The main issue of high-speed, single-wavelength upstream OFDMA-PON arises from optical beating interference noise. Because the sub-channels are allocated dynamically to multiple access users over same nominal wavelength, it generates the optical beating interference among upstream signals. In this paper, we proposed a novel scheme using self-homodyne balanced detection in the optical line terminal (OLT) to reduce OBI noise which is generated in the uplink transmission of OFDMA-PON system. When multiple OFDMA sub-channels over the same nominal wavelength are received at the same time in the proposed architecture, OBI noises can be removed using balanced detection. Using discrete multitone modulation (DMT) to generate real valued OFDM signals, the proposed technique is verified through experimental demonstration.

    An orthogonal frequency-division multiplexing access (OFDMA) based visible light communication (VLC) system is proposed in this paper. The architecture of the proposed system is divided into several VLC cells, which is defined in this paper. The deployment and upgrade of the system involve only simple combination of the VLC cells. Hence it is economically advantageous. To guarantee smooth communication, nearly equal data rate is provided at every location within the system with no concern on the system scale. The user location monitor strategy is also discussed to solve the region division issues. The characteristics of the proposed system are analyzed in detail in this paper. A one-dimensional experiment was demonstrated with 13.6 Mb/s data rate.

  7. Ant Colony Optimization Algorithm for Centralized Dynamic Channel Allocation in Multi-Cell OFDMA Systems

    Kim, Hyo-Su; Kim, Dong-Hoi

    The dynamic channel allocation (DCA) scheme in multi-cell systems causes serious inter-cell interference (ICI) problem to some existing calls when channels for new calls are allocated. Such a problem can be addressed by advanced centralized DCA design that is able to minimize ICI. Thus, in this paper, a centralized DCA is developed for the downlink of multi-cell orthogonal frequency division multiple access (OFDMA) systems with full spectral reuse. However, in practice, as the search space of channel assignment for centralized DCA scheme in multi-cell systems grows exponentially with the increase of the number of required calls, channels, and cells, it becomes an NP-hard problem and is currently too complicated to find an optimum channel allocation. In this paper, we propose an ant colony optimization (ACO) based DCA scheme using a low-complexity ACO algorithm which is a kind of heuristic algorithm in order to solve the aforementioned problem. Simulation results demonstrate significant performance improvements compared to the existing schemes in terms of the grade of service (GoS) performance and the forced termination probability of existing calls without degrading the system performance of the average throughput.

    We propose and demonstrate a novel optical orthogonal frequency-division multiple access (OFDMA)-based metro-access integrated network with dynamic resource allocation. It consists of a single fiber OFDMA ring and many single fiber OFDMA trees, which transparently integrates metropolitan area networks with optical access networks. The single fiber OFDMA ring connects the core network and the central nodes (CNs), the CNs are on demand reconfigurable and use multiple orthogonal sub-carriers to realize parallel data transmission and dynamic resource allocation, meanwhile, they can also implement flexible power distribution. The remote nodes (RNs) distributed in the user side are connected by the single fiber OFDMA trees with the corresponding CN. The obtained results indicate that our proposed metro-access integrated network is feasible and the power distribution is agile.

  9. Hybrid Resource Allocation Scheme with Proportional Fairness in OFDMA-Based Cognitive Radio Systems

    NASA Astrophysics Data System (ADS)

    Li, Li; Xu, Changqing; Fan, Pingzhi; He, Jian

    In this paper, the resource allocation problem for proportional fairness in hybrid Cognitive Radio (CR) systems is studied. In OFDMA-based CR systems, traditional resource allocation algorithms can not guarantee proportional rates among CR users (CRU) in each OFDM symbol because the number of available subchannels might be smaller than that of CRUs in some OFDM symbols. To deal with this time-varying nature of available spectrum resource, a hybrid CR scheme in which CRUs are allowed to use subchannels in both spectrum holes and primary users (PU) bands is adopted and a resource allocation algorithm is proposed to guarantee proportional rates among CRUs with no undue interference to PUs.

    The technique of Orthogonal frequency multiplexing (OFDM) is used to mitigate the multipath effects and to achieve better data rate. When these systems are extended to enable multiple access wireless multimedia communications they are more beneficial. The performance of the OFDM systems degrades with frequency offset and phase offset. The OFDM multiple access (OFDMA) technology allots groups of the OFDM subcarriers allocated to different users for transmission. In this paper we study the interference effects of the individual subcarriers with the neighbouring subcarriers which also plays a role in the system degradation is termed as Multiuser Interference (MUI). The effect of Carrier frequency offset (CFO) on these systems is also taken in account. There are conventional CFO compensation methods for OFDMA systems the CFOs are usually compensated by directly eliminating the intercarrier interference (ICI) caused by the residual CFOs for individual users.

    Three-dimensional (3D) video is expected to be a “killer app” for OFDMA-based broadband wireless systems. The main limitation of 3D video streaming over a wireless system is the shortage of radio resources due to the large size of the 3D traffic. This paper presents a novel resource allocation strategy to address this problem. In the paper, the video-plus-depth 3D traffic type is considered. The proposed resource allocation strategy focuses on the relationship between 2D video and the depth map, handling them with different priorities. It is formulated as an optimization problem and is solved using a suboptimal heuristic algorithm. Numerical results show that the proposed scheme provides a better quality of service compared to conventional schemes. PMID:25250377

    Lv, Gangming; Zhu, Shihua; Hui, Hui

    Multi-cell resource allocation under minimum rate request for each user in OFDMA networks is addressed in this paper. Based on Lagrange dual decomposition theory, the joint multi-cell resource allocation problem is decomposed and modeled as a limited-cooperative game, and a distributed multi-cell resource allocation algorithm is thus proposed. Analysis and simulation results show that, compared with non-cooperative iterative water-filling algorithm, the proposed algorithm can remarkably reduce the ICI level and improve overall system performances.

    2015-01-01

    In this paper, a distributed synchronization technique based on a bio-inspired algorithm is proposed for an orthogonal frequency division multiple access (OFDMA)-based wireless mesh network (WMN) with a time difference of arrival. The proposed time- and frequency-synchronization technique uses only the signals received from the neighbor nodes, by considering the effect of the propagation delay between the nodes. It achieves a fast synchronization with a relatively low computational complexity because it is operated in a distributed manner, not requiring any feedback channel for the compensation of the propagation delays. In addition, a self-organization scheme that can be effectively used to construct 1-hop neighbor nodes is proposed for an OFDMA-based WMN with a large number of nodes. The performance of the proposed technique is evaluated with regard to the convergence property and synchronization success probability using a computer simulation. PMID:26225974

    In this paper, we propose a distributed MAC protocol for OFDMA-based wireless mobile ad hoc multihop networks, in which the resource reservation and data transmission procedures are operated in a distributed manner. A frame format is designed considering the characteristics of OFDMA that each node can transmit or receive data to or from multiple nodes simultaneously. Under this frame structure, we propose a distributed resource management method including network state estimation and resource reservation processes. We categorize five types of logical errors according to their root causes and show that two of the logical errors are inevitable while three of them are avoided under the proposed distributed MAC protocol. In addition, we provide a systematic method to determine the advertisement period of each node by presenting a clear relation between the accuracy of estimated network states and the signaling overhead. We evaluate the performance of the proposed protocol in respect of the reservation success rate and the success rate of data transmission. Since our method focuses on avoiding logical errors, it could be easily placed on top of the other resource allocation methods focusing on the physical layer issues of the resource management problem and interworked with them.

    The goal of the study presented in this paper is to investigate the performance of a new subcarrier allocation strategy for Orthogonal Frequency Division Multiple Access (OFDMA) multicellular networks which employ Multiple Input Multiple Output (MIMO) architecture. For this reason, a hybrid system-link level simulator has been developed executing independent Monte Carlo (MC) simulations in parallel. Up to two tiers of cells around the central cell are taken into consideration and increased loading per cell. The derived results indicate that this strategy can provide up to 12% capacity gain for 16-QAM modulation and two tiers of cells around the central cell in a symmetric 2 × 2 MIMO configuration. This gain is derived when comparing the proposed strategy to the traditional approach of allocating subcarriers that maximize only the desired user's signal. PMID:24683351

    Phase diversity of coherent optical communication provides spectrally efficient higher-order modulation for optical communications. However, in-phase/quadrature (IQ) imbalance in coherent optical communication degrades transmission performance by introducing unwanted signal distortions. In a coherent optical orthogonal frequency division multiple access (OFDMA) passive optical network (PON), IQ imbalance-induced signal distortions degrade transmission performance by interferences of mirror subcarriers, inter-symbol interference (ISI), and inter-channel interference (ICI). We propose parallel-channel discrete multitone (DMT) transmission to mitigate transceiver IQ imbalance-induced signal distortions in coherent orthogonal frequency division multiplexing (OFDM) transmissions. We experimentally demonstrate the effectiveness of parallel-channel DMT transmission compared with that of OFDM transmission in the presence of IQ imbalance.

  19. Two-Level Scheduling for Video Transmission over Downlink OFDMA Networks

    2016-01-01

    This paper presents a two-level scheduling scheme for video transmission over downlink orthogonal frequency-division multiple access (OFDMA) networks. It aims to maximize the aggregate quality of the video users subject to the playback delay and resource constraints, by exploiting the multiuser diversity and the video characteristics. The upper level schedules the transmission of video packets among multiple users based on an overall target bit-error-rate (BER), the importance level of packet and resource consumption efficiency factor. Instead, the lower level renders unequal error protection (UEP) in terms of target BER among the scheduled packets by solving a weighted sum distortion minimization problem, where each user weight reflects the total importance level of the packets that has been scheduled for that user. Frequency-selective power is then water-filled over all the assigned subcarriers in order to leverage the potential channel coding gain. Realistic simulation results demonstrate that the proposed scheme significantly outperforms the state-of-the-art scheduling scheme by up to 6.8 dB in terms of peak-signal-to-noise-ratio (PSNR). Further test evaluates the suitability of equal power allocation which is the common assumption in the literature. PMID:26906398

    Underwater acoustic wireless sensor networks (UAWSNs) have many applications across various civilian and military domains. However, they suffer from the limited available bandwidth of acoustic signals and harsh underwater conditions. In this work, we present an Orthogonal Frequency Division Multiple Access (OFDMA)-based Media Access Control (MAC) protocol that is configurable to suit the operating requirements of the underwater sensor network. The protocol has three modes of operation, namely random, equal opportunity and energy-conscious modes of operation. Our MAC design approach exploits the multi-path characteristics of a fading acoustic channel to convert it into parallel independent acoustic sub-channels that undergo flat fading. Communication between node pairs within the network is done using subsets of these sub-channels, depending on the configurations of the active mode of operation. Thus, the available limited bandwidth gets fully utilized while completely avoiding interference. We derive the mathematical model for optimal power loading and subcarrier selection, which is used as basis for all modes of operation of the protocol. We also conduct many simulation experiments to evaluate and compare our protocol with other Code Division Multiple Access (CDMA)-based MAC protocols. PMID:23012517

    The increase in internet traffic, number of users, and availability of mobile devices poses a challenge to wireless technologies. In long-term evolution (LTE) advanced system, heterogeneous networks (HetNet) using centralized coordinated multipoint (CoMP) transmitting radio over optical fibers (LTE A-ROF) have provided a feasible way of satisfying user demands. In this paper, an orthogonal wavelet division multiple-access (OWDMA) processor architecture is proposed, which is shown to be better suited to LTE advanced systems as compared to orthogonal frequency division multiple access (OFDMA) as in LTE systems 3GPP rel.8 (3GPP, http://www.3gpp.org/DynaReport/36300.htm). ROF systems are a viable alternative to satisfy large data demands; hence, the performance in ROF systems is also evaluated. To validate the architecture, the circuit is designed and synthesized on a Xilinx vertex-6 field-programmable gate array (FPGA). The synthesis results show that the circuit performs with a clock period as short as 7.036 ns (i.e., a maximum clock frequency of 142.13 MHz) for transform size of 512. A pipelined version of the architecture reduces the power consumption by approximately 89%. We compare our architecture with similar available architectures for resource utilization and timing and provide performance comparison with OFDMA systems for various quality metrics of communication systems. The OWDMA architecture is found to perform better than OFDMA for bit error rate (BER) performance versus signal-to-noise ratio (SNR) in wireless channel as well as ROF media. It also gives higher throughput and mitigates the bad effect of peak-to-average-power ratio (PAPR).

    2016-02-01

    In passive optical network (PON), orthogonal frequency division multiplexing (OFDM) has been studied actively due to its advantages such as high spectra efficiency (SE), dynamic resource allocation in time or frequency domain, and dispersion robustness. However, orthogonal frequency division multiple access (OFDMA)-PON requires tight synchronization among multiple access signals. If not, frequency orthogonality could not be maintained. Also its sidelobe causes inter-channel interference (ICI) to adjacent channel. To prevent ICI caused by high sidelobes, guard band (GB) is usually used which degrades SE. Thus, OFDMA-PON is not suitable for asynchronous uplink transmission in optical access network. In this paper, we propose intensity modulation/direct detection (IM/DD) based universal filtered multi-carrier (UFMC) PON for asynchronous multiple access. The UFMC uses subband filtering to subsets of subcarriers. Since it reduces sidelobe of each subband by applying subband filtering, it could achieve better performance compared to OFDM. For the experimental demonstration, different sample delay was applied to subbands to implement asynchronous transmission condition. As a result, time synchronization robustness of UFMC was verified in asynchronous multiple access system.

    An approximately multi-user OFDM transceiver was introduced to reduce the multi-access interference (MAI ) due to the carrier frequency offset (CFO) to a negligible amount via precoding by Tsai, Lin and Kuo. In this work, we investigate the performance of this precoded multi-user (PMU) OFDM system in a time-variant channel environment. We analyze and compare the MAI effect caused by time-variant channels in the PMU-OFDM and the OFDMA systems. Generally speaking, the MAI effect consists of two parts. The first part is due to the loss of orthogonality among subchannels for all users while the second part is due to the CFO effect caused by the Doppler shift. Simulation results show that, although OFDMA outperforms the PMU-OFDM transceiver in a fast time-variant environment without CFO, PMU-OFDM outperforms OFDMA in a slow time-variant channel via the use of M/2 symmetric or anti-symmetric codewords of M Hadamard-Walsh codes.

    Optical-orthogonal frequency division multiplexing (O-OFDM) is an effective scheme for visible light communications (VLC), offering a candid extension to multiple access (MA) scenarios, i.e., O-OFDMA. However, O-OFDMA exhibits high peak-to-average power ratio (PAPR), which exacerbates the non-linear distortions from the light emitting diode (LED). To overcome high PAPR while sustaining MA, optical-single-carrier frequency-division multiple access (O-SCFDMA) is used. For both O-OFDMA and O-SCFDMA, Hermitian symmetry (HS) constraint is imposed in frequency-domain (FD) to obtain a real-valued time-domain (TD) signal for intensity modulation-direct detection (IM-DD) implementation of VLC. Howbeit, HS results in an increase of PAPR for O-SCFDMA. In this regard, we propose HS free (HSF) O-SCFDMA (HSFO-SCFDMA). We compare HSFO-SCFDMA with several approaches in key parameters, such as, bit error rate (BER), optical power penalty, PAPR, quantization, electrical power efficiency and system complexity. BER performance and optical power penalty is evaluated considering multipath VLC channel and taking into account the bandwidth limitation of LED in combination with its optimized driver. It is illustrated that HSFO-SCFDMA outperforms other alternatives.

    We propose and experimentally demonstrate a multiuser orthogonal frequency-division multiple access passive optical network (OFDMA-PON) with source-free optical network units (ONUs), enabled by tunable optical frequency comb generation technology. By cascading a phase modulator (PM) and an intensity modulator and dynamically controlling the peak-to-peak voltage of a PM driven signal, a tunable optical frequency comb source can be generated. It is utilized to assist the configuration of a multiple source-free ONUs enhanced OFDMA-PON where simultaneous and interference-free multiuser upstream transmission over a single wavelength can be efficiently supported. The proposed multiuser OFDMA-PON is scalable and cost effective, and its feasibility is successfully verified by experiment.

    Education in systems-based practice is a required component of all postgraduate medical education programs in the United States. Competency in this area requires that trainees have an understanding of the health care system sufficient to provide optimal care to patients. Most trainees in residency programs have little understanding of the complexities and challenges of present-day practice in the current system of care and consider themselves unprepared to undertake this activity following completion of training. Training in practice management in residency programs has not been emphasized as an important component of systems-based practice. Historically, practice management training in residency programs has been done using a fully didactic model, and residents have expressed a desire to learn this skill by becoming more directly involved in the operations and management of a practice. The patient visit touches many aspects of the health care system, including clinic operations, insurance, quality, and finances. At our institution, we used the residents' continuity clinic practices as a vehicle to provide education in practice management and systems-based practice by creating a curriculum that included the residents' perceived gaps in knowledge regarding going into practice. This is known as the virtual practice. This curriculum is taught using data obtained from residents' practice to illustrate concepts in many areas, including primary practice operations, malpractice insurance, financial benchmarks, and career planning. Resident self-assessed knowledge of these areas increased after participating in the curriculum, and resident testimonials indicate satisfaction with the project. In addition, residents have become engaged and interested in how their effort translates into performance and how they participate in the health care system.

    The efficient storage and easy retrieval of quality records are a central concern of good family practice. Many physicians starting out in practice have difficulty choosing a practical and lasting system for storing their records. Some who have established practices are installing computers in their offices and finding that their filing systems are worn, outdated, and incompatible with computerized systems. This article describes a new filing system installed simultaneously with a new computer system in a family-practice teaching centre. The approach adopted solved all identifiable problems and is applicable in family practices of all sizes.

    Improving patient safety and quality of care is part of systems-based practice and practice-based learning for residents. We expanded our obstetrics and gynecology department's regularly scheduled morbidity and mortality conferences to teach quality assurance concepts based on patient care on obstetrics and gynecology fourth-year resident rotations. Obstetrics and gynecology fourth-year residents on one of the two rotations each presented and analyzed a systems-based problem they encountered during patient care. They used an online learning module and proposed solutions, many of which were effectively implemented. Over 5 years, case presentations from 33 conferences were available with problems identified in emergency preparedness, coordination of care, scheduling and supervision, communication, medical practice, documentation, and lack of equipment or facilities. Twenty-two of the suggested solutions were partially or totally implemented. Barriers to implementation were identified. In conclusion, a conference presentation by fourth-year residents can identify patient safety problems, aid in their resolution, and suggest changes to patient care while teaching the principles of systems-based practice and practice-based learning.

    Of all the clinical competencies, the least understood are Systems-Based Practice and Practice-Based Learning and Improvement. With a shift to competency-based education and evaluation across the spectrum of surgical education and practice, a clear understanding of the power and utility of each competency is paramount. Health care operates as a complex adaptive system, with dynamics foreign to many health care professionals and educators. The adaptation and evolution of such a system is related directly to both the individual and the organizational learning of the agents within the system and knowledge management strategies. Far from being "difficult," Systems-Based Practice and Practice-Based Learning form the heart of quality improvement initiatives and future productivity advances in health care.

    Phenomenon: Systems thinking is the cornerstone of systems-based practice (SBP) and a core competency in medicine and health sciences. Literature regarding how to teach or apply systems thinking in practice is limited. This study aimed to understand how educators in medicine, physical therapy, physician assistant, nursing, and speech-language pathology education programs teach and assess systems thinking and SBP. Twenty-six educators from seven different degree programs across the five professions were interviewed and program descriptions and relevant course syllabi were reviewed. Qualitative analysis was iterative and incorporated inductive and deductive methods as well as a constant comparison of units of data to identify patterns and themes. Six themes were identified: 1) participants described systems thinking as ranging across four major levels of healthcare (i.e., patient, care team, organization, and external environment); 2) participants associated systems thinking with a wide range of activities across the curriculum including quality improvement, Inter-professional education (IPE), error mitigation, and advocacy; 3) the need for healthcare professionals to understand systems thinking was primarily externally driven; 4) participants perceived that learning systems thinking occurred mainly informally and experientially rather than through formal didactic instruction; 5) participants characterized systems thinking content as interspersed across the curriculum and described a variety of strategies for teaching and assessing it; 6) participants indicated a structured framework and inter-professional approach may enhance teaching and assessment of systems thinking. Insights: Systems thinking means different things to different health professionals. Teaching and assessing systems thinking across the health professions will require further training and practice. Tools, techniques, taxonomies and expertise outside of healthcare may be used to enhance the teaching

    Health and well-being are the result of a series of complex processes in which an individual interacts with other people and the environment. A systematic approach ensures incorporation of individual, ecological, social and political factors. However, interactions between these factors can be overlooked within a systematical approach. A systemic approach can provide additional information by incorporating interactions and communication. The opportunities of a systems thinking perspective for health promotion were investigated for this paper. Although others have also made attempts to explore systems thinking in the field of health promotion, the implications of systems thinking in practice need attention. Other fields such as agricultural extension studies, organizational studies and development studies provide useful experiences with the use of a systems thinking perspective in practice. Building on experiences from these fields, we give a theoretical background in which processes of social learning and innovation play an important role. From this background, we derive an overview of important concepts for the practical application of a systems thinking perspective. These concepts are the structure of the system, meanings attached to actions, and power relations between actors. To make these concepts more explicit and reduce the theoretical character of systems thinking, we use an illustration to elaborate on these concepts in practice. For this purpose, we describe a health promotion partnership in The Netherlands using the concepts structure, meaning and power relations. We show how a systems perspective increases insight in the functioning of a partnership and how this can facilitate processes of social learning and innovation. This article concludes by identifying future opportunities and challenges in adopting systems thinking for health promotion practice. A systems perspective towards health promotion can help projects reaching a more integral and

    Each of the five systems approaches discussed in this volume: system dynamics (SD), the viable systems model (VSM), strategic options development and analysis (SODA), soft systems methodology (SSM) and critical systems heuristics (CSH) has a pedigree. Not in the sense of the sometimes absurd spectacle of animals paraded at dog shows. Rather, their pedigree derives from their systems foundations, their capacity to evolve and their flexibility in use. None of the five approaches has developed out of use in restricted and controlled contexts of either low or high levels of complicatedness. Neither has any one of them evolved as a consequence of being applied only to situations with either presumed stakeholder agreement on purpose, or courteous disagreement amongst stakeholders, or stakeholder coercion. The compilation is not a celebration of abstract ‘methodologies', but of theoretically robust approaches that have a genuine pedigree in practice.

    From its inception in the defense and aerospace industries, SE has applied holistic, interdisciplinary tools and work-process to improve the design and management of 'large, complex engineering projects.' The traditional scope of engineering in general embraces the design, development, production, and operation of physical systems, and SE, as originally conceived, falls within that scope. While this 'traditional' view has expanded over the years to embrace wider, more holistic applications, much of the literature and training currently available is still directed almost entirely at addressing the large, complex, NASA and defense-sized systems wherein the 'ideal' practice of SE provides the cradle-to-gravemore » foundation for system development and deployment. Under such scenarios, systems engineers are viewed as an integral part of the system and project life-cycle from conception to decommissioning. In far less 'ideal' applications, SE principles are equally applicable to a growing number of complex systems and projects that need to be 'rescued' from overwhelming challenges that threaten imminent failure. The medical profession provides a unique analogy for this latter concept and offers a useful paradigm for tailoring our 'practice' of SE to address the unexpected dynamics of applying SE in the real world. In short, we can be much more effective as systems engineers as we change some of the paradigms under which we teach and 'practice' SE.« less

    In the field of systems biology, biological reaction networks are usually modelled by ordinary differential equations. A sub-class, the S-systems representation, is a widely used form of modelling. Existing S-systems identification techniques assume that the system itself is always structurally identifiable. However, due to practical limitations, biological reaction networks are often only partially measured. In addition, the captured data only covers a limited trajectory, therefore data can only be considered as a local snapshot of the system responses with respect to the complete set of state trajectories over the entire state space. Hence the estimated model can only reflect partial system dynamics and may not be unique. To improve the identification quality, the structural and practical identifiablility of S-system are studied. The S-system is shown to be identifiable under a set of assumptions. Then, an application on yeast fermentation pathway was conducted. Two case studies were chosen; where the first case is based on a larger state trajectories and the second case is based on a smaller one. By expanding the dataset which span a relatively larger state space, the uncertainty of the estimated system can be reduced. The results indicated that initial concentration is related to the practical identifiablity.

We have designed and implemented a rotation in Systems-Based Practice focused on the interrelationships of patient care, clinical revenue, and the physician's role within health care systems. Experiential learning occurs during a 5-day rotation through 26 areas encompassing the clinical revenue cycle, guided by "expert" staff. Using a reversal of the TV show Survivor, house staff begin conceptually "alone" and discover they are members of a large, dedicated team. Assessment results, including a system knowledge test and course evaluations, are presented. Twenty-five residents from four clinical departments participated in Year 1.

    Despite enormous advances in information systems, the process by which most medical practices select them has remained virtually unchanged for decades: the request for proposal (RFP). Unfortunately, vendors have learned ways to minimize the value of RFP checklists to where purchasers now learn little about the system functionality. The authors describe a selection methodology that replaces the RFP with scored demos, reviews of vendor user manuals and mathematically structured reference checking. In a recent selection process at a major medical center, these techniques yielded greater user buy-in and favorable contract terms as well.

    Physicians in group practices must gain a competitive edge to survive in a healthcare environment in which cost efficiency has become critical to success. One tool that can help them is a cost accounting system that yields reliable, detailed data on the costs of delivering care. Such a system not only can enable physicians and group administrators to manage their operations more cost-effectively, but also can help them accurately assess the potential profitability of prospective managed care plans. An otolaryngology practice located in Mississippi provides a model for developing a cost accounting system that can be applied to physician group practices.

    2017-01-01

    Systems engineering involves both the integration of the system and the integration of the disciplines which develop and operate the system. Integrating the disciplines is a sociological effort to bring together different groups, who often have different terminology, to achieve a common goal, the system. The focus for the systems engineer is information flow through the organization, between the disciplines, to ensure the system is developed and operated will all relevant information informing system decisions. The practical application of the sociology in systems engineering brings in various organizational development concepts including the principles of planned renegotiation and the application of principles to address information barriers created by organizational culture. Concepts such as specification of ignorance, consistent terminology, opportunity structures, role-sets, and the reclama (reconsideration) process are all important sociological approaches that help address the organizational social structure (culture). In bringing the disciplines together, the systems engineer must also be wary of social ambivalence, social anomie, social dysfunction, and insider-outsider behavior. Unintended consequences can result when these social issues are present. These issues can occur when localized subcultures shift from the overarching organizational culture, or when the organizational culture prevents achievement of system goals. These sociological principles provide the systems engineer with key approaches to manage the information flow through the organization as the disciplines are integrated and share their information and provides key sociological barriers to information flow through the organization. This paper will discuss the practical application of sociological principles to systems engineering.

    2013-06-01

    The systems approach is arguably the dominant concept within accident analysis research. Viewing accidents as a result of uncontrolled system interactions, it forms the theoretical basis of various systemic accident analysis (SAA) models and methods. Despite the proposed benefits of SAA, such as an improved description of accident causation, evidence within the scientific literature suggests that these techniques are not being used in practice and that a research-practice gap exists. The aim of this study was to explore the issues stemming from research and practice which could hinder the awareness, adoption and usage of SAA. To achieve this, semi-structured interviews were conducted with 42 safety experts from ten countries and a variety of industries, including rail, aviation and maritime. This study suggests that the research-practice gap should be closed and efforts to bridge the gap should focus on ensuring that systemic methods meet the needs of practitioners and improving the communication of SAA research.

    2006-01-01

    In FY 2004, JPL launched an initiative to improve the way it practices systems engineering. The Lab's senior management formed the Systems Engineering Advancement (SEA) Project in order to "significantly advance the practice and organizational capabilities of systems engineering at JPL on flight projects and ground support tasks." The scope of the SEA Project includes the systems engineering work performed in all three dimensions of a program, project, or task: 1. the full life-cycle, i.e., concept through end of operations 2. the full depth, i.e., Program, Project, System, Subsystem, Element (SE Levels 1 to 5) 3. the full technical scope, e.g., the flight, ground and launch systems, avionics, power, propulsion, telecommunications, thermal, etc. The initial focus of their efforts defined the following basic systems engineering functions at JPL: systems architecture, requirements management, interface definition, technical resource management, system design and analysis, system verification and validation, risk management, technical peer reviews, design process management and systems engineering task management, They also developed a list of highly valued personal behaviors of systems engineers, and are working to inculcate those behaviors into members of their systems engineering community. The SEA Project is developing products, services, and training to support managers and practitioners throughout the entire system lifecycle. As these are developed, each one needs to be systematically deployed. Hence, the SEA Project developed a deployment process that includes four aspects: infrastructure and operations, communication and outreach, education and training, and consulting support. In addition, the SEA Project has taken a proactive approach to organizational change management and customer relationship management - both concepts and approaches not usually invoked in an engineering environment.

    NASA's Constellation program provided a unique testbed for Human Systems Integration (HSI) as a fundamental element of the Systems Engineering process. Constellation was the first major program to have HSI mandated by NASA's Human Rating document. Proper HSI is critical to the success of any project that relies on humans to function as operators, maintainers, or controllers of a system. HSI improves mission, system and human performance, significantly reduces lifecycle costs, lowers risk and minimizes re-design. Successful HSI begins with sufficient project schedule dedicated to the generation of human systems requirements, but is by no means solely a requirements management process. A top-down systems engineering process that recognizes throughout the organization, human factors as a technical discipline equal to traditional engineering disciplines with authority for the overall system. This partners with a bottoms-up mechanism for human-centered design and technical issue resolution. The Constellation Human Systems Integration Group (HSIG) was a part of the Systems Engineering and Integration (SE&I) organization within the program office, and existed alongside similar groups such as Flight Performance, Environments & Constraints, and Integrated Loads, Structures and Mechanisms. While the HSIG successfully managed, via influence leadership, a down-and-in Community of Practice to facilitate technical integration and issue resolution, it lacked parallel top-down authority to drive integrated design. This presentation will discuss how HSI was applied to Constellation, the lessons learned and best practices it revealed, and recommendations to future NASA program and project managers.

    There is a critical need for nurses and interprofessional healthcare providers to implement systems thinking (ST) across international borders, addressing incivility and its perilous effects on patient quality and safety. An estimated one million patients die in hospitals worldwide due to avoidable patient-related errors. Establishing safe and civil workplaces using ST is paramount to promoting clear, level-headed thinking from which patient-centered nursing actions can impact health systems. The purpose of the paper is to answer the research question, What ST evidence fosters the effect of workplace civility in practice settings? Whittemore and Knafl's integrative review method guided this study. The quality of articles was determined using Chu et al.'s Mixed Methods Assessment Tool. Thirty-eight studies were reviewed. Themes emerged describing antecedents and consequences of incivility as embedded within complex systems, suggesting improvements for civility and systems/ST in nursing practice. This integrative review provides information about worldwide incivility in nursing practice from a systems perspective. Several models are offered as a means of promoting civility in nursing practice to improve patient quality and safety. Further study is needed regarding incivility and resultant effects on patient quality and safety. © 2018 Wiley Periodicals, Inc.

    Systematic client feedback (SCF) is increasingly employed in mental health services worldwide. While research supports its efficacy over treatment as usual, clinicians, especially those who highly value relational practices, may be concerned that routine data collection detracts from clinical process. This article describes one SCF system, the Partners for Change Outcome Management System (PCOMS), along a normative (standardized measurement) to communicative (conversational) continuum, highlighting PCOMS' origins in everyday clinical practice. The authors contend that PCOMS represents "both/and," providing a valid signal of client progress while facilitating communicative process particularly prized by family therapists steeped in relational traditions. The article discusses application of PCOMS in systemic practice and describes how it actualizes time-honored family therapy approaches. The importance of giving voice to individualized client experience is emphasized. © 2018 Family Process Institute.

    2017-01-17

    Parameters of mathematical models of the cardiovascular system can be used to monitor cardiovascular state, such as total stressed blood volume status, vessel elastance and resistance. To do so, the model parameters have to be estimated from data collected at the patient's bedside. This work considers a seven-parameter model of the cardiovascular system and investigates whether these parameters can be uniquely determined using indices derived from measurements of arterial and venous pressures, and stroke volume. An error vector defined the residuals between the simulated and reference values of the seven clinically available haemodynamic indices. The sensitivity of this error vector to each model parameter was analysed, as well as the collinearity between parameters. To assess practical identifiability of the model parameters, profile-likelihood curves were constructed for each parameter. Four of the seven model parameters were found to be practically identifiable from the selected data. The remaining three parameters were practically non-identifiable. Among these non-identifiable parameters, one could be decreased as much as possible. The other two non-identifiable parameters were inversely correlated, which prevented their precise estimation. This work presented the practical identifiability analysis of a seven-parameter cardiovascular system model, from limited clinical data. The analysis showed that three of the seven parameters were practically non-identifiable, thus limiting the use of the model as a monitoring tool. Slight changes in the time-varying function modeling cardiac contraction and use of larger values for the reference range of venous pressure made the model fully practically identifiable.

    2013-01-01

    Purpose The Accreditation Council for Graduate Medical Education restructured its accreditation system to be based on educational outcomes in six core competencies. Systems-based practice is one of the six core competencies. The purpose of this report is to describe Weill Cornell Medical College's Internal Medicine Residency program curriculum for systems-based practice (SBP) and its evaluation process. Methods To examine potential outcomes of the POCHS curriculum, an evaluation was conducted, examining participants': (1) knowledge gain; (2) course ratings; and (3) qualitative feedback. Results On average, there was a 19 percentage point increase in knowledge test scores for all three cohorts. The course was rated overall highly, receiving an average of 4.6 on a 1–5 scale. Lastly, the qualitative comments supported that the material is needed and valued. Conclusion The course, entitled Perspectives on the Changing Healthcare System (POCHS) and its evaluation process support that systems-based practice is crucial to residency education. The course is designed not only to educate residents about the current health care system but also to enable them to think critically about the risk and benefits of the changes. POCHS provides a framework for teaching and assessing this competency and can serve as a template for other residency programs looking to create or restructure their SBP curriculum. PMID:24001523

  1. Navigating systems ideas for health practice: Towards a common learning device.

    PubMed

    Reynolds, Martin; Sarriot, Eric; Swanson, Robert Chad; Rusoja, Evan

    2018-06-01

    Systems thinking and reference to complexity science have gained currency in health sector practice and research. The extent to which such ideas might represent a mere passing fad or might more usefully be mobilized to tackle wicked problems in health systems is a concern underpinning this paper. Developing the usefulness of the systems idea requires appreciating how systems ideas are used essentially as constructs conceptually bounded by practitioners. Systems are used for purposes of understanding and engaging the reality of health issues, with the intent of transforming the reality into one that is more manageable, equitable, and sustainable. We examine some manifestations of the systems idea in health practice and the traditions of systems practice that variously make use of them. This provides a platform for proposing a systems thinking in (health) practice heuristic: a learning device supporting how different tools and methods can address "wicked problems" in health praxis. The device is built on the use of "conversation" as a metaphor to help practitioners use systems ideas in tandem with existing disciplinary and professional skills and methods. We consider how the application of the heuristic requires, and helps to develop, human characteristics of humility, empathy, and recognition of fallibility. © 2018 John Wiley & Sons, Ltd.

    Meaningful education of residents in systems-based practice is notoriously challenging, despite its recognition as 1 of the 6 Accreditation Council for Graduate Medical Education core competencies. To address this challenge, surgery residents and other members of the health care team were organized into interdisciplinary workgroups that were tasked with developing solutions to "systems issues" confronted on a daily basis. The project's goals included providing more meaningful, hands-on educational experience for residents in system-based practice, while also generating practical solutions to workflow issues through interprofessional collaboration. Project participants included all surgery residents at the University of Virginia in Charlottesville, VA, as well as surgical health care professionals across all disciplines. Participants were organized into workgroups. Over the course of 3 sessions, each of 1-hour, each workgroup identified commonly encountered systems issues, chose 1 issue to address, and determined an implementable solution for this issue. In total, 140 participants were divided among 13 workgroups. Workgroup topics ranged from improving paging etiquette to standardizing interdisciplinary communication. In total, 9 of the 13 proposals have been piloted or fully implemented as standard practice at our institution, either within a single unit or over the entire health system. This project demonstrates an innovative approach toward resident education in system-based practice, providing residents with a hands-on experience in problem solving from a systems perspective. These interdisciplinary workgroups generated effective solutions to issues that were meaningful to frontline health care providers. Interdisciplinary collaboration within the workgroups served as a valuable team-building exercise to improve relations between the disciplines. This project can serve as a model for other institutions desiring meaningful education in the Accreditation Council

  3. Feedback Control Systems Loop Shaping Design with Practical Considerations

    Kopsakis, George

    2007-01-01

    This paper describes loop shaping control design in feedback control systems, primarily from a practical stand point that considers design specifications. Classical feedback control design theory, for linear systems where the plant transfer function is known, has been around for a long time. But it s still a challenge of how to translate the theory into practical and methodical design techniques that simultaneously satisfy a variety of performance requirements such as transient response, stability, and disturbance attenuation while taking into account the capabilities of the plant and its actuation system. This paper briefly addresses some relevant theory, first in layman s terms, so that it becomes easily understood and then it embarks into a practical and systematic design approach incorporating loop shaping design coupled with lead-lag control compensation design. The emphasis is in generating simple but rather powerful design techniques that will allow even designers with a layman s knowledge in controls to develop effective feedback control designs.

  4. Communities of Practice and Social Learning Systems: the Career of a Concept

    NASA Astrophysics Data System (ADS)

    Wenger, Etienne

    The concept of community of practice was not born in the systems theory tradition. It has its roots in attempts to develop accounts of the social nature of human learning inspired by anthropology and social theory (Lave, 1988; Bourdieu, 1977; Giddens, 1984; Foucault, 1980; Vygotsky, 1978). But the concept of community of practice is well aligned with the perspective of systems traditions. A community of practice itself can be viewed as a simple social system. And a complex social system can be viewed as constituted by interrelated communities of practice. In this essay I first explore the systemic nature of the concept at these two levels. Then I use this foundation to look at the applications of the concept, some of its main critiques, and its potential for developing a social discipline of learning.

    The success of any dental practice depends, among other factors, on the critical role of staff employees. In order to encourage desired staff behaviors, incentive systems can be designed for employee dentists, assistants/hygienists and managers. A survey of dental franchises was conducted in 1987 for the purpose of examining their incentive control systems. The specific incentives employed by these dental franchises for their employees are analyzed. The implications of these incentive systems used by dental franchise organizations for all dental practices are then discussed.

    Several studies documented substantial variation in medical practice patterns, but physicians often do not have adequate information on the cumulative clinical and financial effects of their decisions. The purpose of developing an expert system for the analysis of clinical practice patterns was to assist providers in analyzing and improving the process and outcome of patient care. The developed QFES (Quality Feedback Expert System) helps users in the definition and evaluation of measurable quality improvement objectives. Based on objectives and actual clinical data, several measures can be calculated (utilization of procedures, annualized cost effect of using a particular procedure, and expected utilization based on peer-comparison and case-mix adjustment). The quality management rules help to detect important discrepancies among members of the selected provider group and compare performance with objectives. The system incorporates a variety of data and knowledge bases: (i) clinical data on actual practice patterns, (ii) frames of quality parameters derived from clinical practice guidelines, and (iii) rules of quality management for data analysis. An analysis of practice patterns of 12 family physicians in the management of urinary tract infections illustrates the use of the system.

    In this paper, 4 × 4 multiple-input multiple-output (MIMO) radio over 7-core fiber system based on sparse code multiple access (SCMA) and OFDM/OQAM techniques is proposed. No cyclic prefix (CP) is required by properly designing the prototype filters in OFDM/OQAM modulator, and non-orthogonally overlaid codewords by using SCMA is help to serve more users simultaneously under the condition of using equal number of time and frequency resources compared with OFDMA, resulting in the increase of spectral efficiency (SE) and system capacity. In our experiment, 11.04 Gb/s 4 × 4 MIMO SCMA-OFDM/OQAM signal is successfully transmitted over 20 km 7-core fiber and 0.4 m air distance in both uplink and downlink. As a comparison, 6.681 Gb/s traditional MIMO-OFDM signal with the same occupied bandwidth has been evaluated for both uplink and downlink transmission. The experimental results show that SE could be increased by 65.2% with no bit error rate (BER) performance degradation compared with the traditional MIMO-OFDM technique.

    Lin, Hanjun; Hsu, Yeh-Liang; Hsu, Ming-Shinn; Cheng, Chih-Ming

    2013-07-01

    Expert systems have been widely used in medical and healthcare practice for various purposes. In addition to vital sign data, important concerns in telehealthcare include the compliance with the measurement prescription, the accuracy of vital sign measurements, and the functioning of vital sign meters and home gateways. However, few expert system applications are found in the telehealthcare domain to address these issues. This article presents an expert system application for one of the largest commercialized telehealthcare practices in Taiwan by Min-Sheng General Hospital. The main function of the Telehealthcare Expert System (TES) developed in this research is to detect and classify events based on the measurement data transmitted to the database at the call center, including abnormality of vital signs, violation of vital sign measurement prescriptions, and malfunction of hardware devices (home gateway and vital sign meter). When the expert system detects an abnormal event, it assigns an "urgent degree" and alerts the nursing team in the call center to take action, such as phoning the patient for counseling or to urge the patient to return to the hospital for further tests. During 2 years of clinical practice, from 2009 to 2011, 19,182 patients were served by the expert system. The expert system detected 41,755 events, of which 22.9% indicated abnormality of vital signs, 75.2% indicated violation of measurement prescription, and 1.9% indicated malfunction of devices. On average, the expert system reduced by 76.5% the time that the nursing team in the call center spent in handling the events. The expert system helped to reduce cost and improve quality of the telehealthcare service.

    Over the past 7 decades, theories in the systems and complexity sciences have had a major influence on academic thinking and research. We assessed the impact of complexity science on general practice/family medicine. We performed a historical integrative review using the following systematic search strategy: medical subject heading [humans] combined in turn with the terms complex adaptive systems, nonlinear dynamics, systems biology, and systems theory, limited to general practice/family medicine and published before December 2010. A total of 16,242 articles were retrieved, of which 49 were published in general practice/family medicine journals. Hand searches and snowballing retrieved another 35. After a full-text review, we included 56 articles dealing specifically with systems sciences and general/family practice. General practice/family medicine engaged with the emerging systems and complexity theories in 4 stages. Before 1995, articles tended to explore common phenomenologic general practice/family medicine experiences. Between 1995 and 2000, articles described the complex adaptive nature of this discipline. Those published between 2000 and 2005 focused on describing the system dynamics of medical practice. After 2005, articles increasingly applied the breadth of complex science theories to health care, health care reform, and the future of medicine. This historical review describes the development of general practice/family medicine in relation to complex adaptive systems theories, and shows how systems sciences more accurately reflect the discipline's philosophy and identity. Analysis suggests that general practice/family medicine first embraced systems theories through conscious reorganization of its boundaries and scope, before applying empirical tools. Future research should concentrate on applying nonlinear dynamics and empirical modeling to patient care, and to organizing and developing local practices, engaging in community development, and influencing

    2010-04-01

    In 1999, the Accreditation Council for Graduate Medical Education endorsed systems-based practice as one of six general competencies. The objective is to explore the paradigm of teaching residents systems-based practice during a women's health rotation that included abortion training in multiple settings. During a routine women's health rotation, residents from two urban family medicine residency programs received early abortion training at a high-volume abortion clinic and their continuity clinic. Thirty-min semistructured interviews were conducted with all 26 residents who rotated between July 2005 and August 2006. Transcripts were analyzed using thematic codes. Through exposure to different healthcare delivery systems, residents learned about systems-based practice, including understanding the failure of the larger system to meet patients' reproductive healthcare needs, differences between two systems, and potential systems barriers they might face as providers. Abortion training in multiple settings may serve as a paradigm for teaching systems-based practice during other rotations that include training in multiple sites.

    Ethical tensions arise daily in health care practice and are frequently related to health care system structures or policies. Collective case study methodology was adopted to examine ethical tensions reported by occupational therapists practicing in different settings in Southwestern Ontario, Canada. Inductive analysis involving multiple layers of coding was conducted. This article focuses on tensions related to systemic constraints. Participants reported ethical tensions related to balancing client priorities with those of health care services. Four themes related to systemic constraints were identified including imposed practices, ineffective processes, resource limitations, and lack of services. Therapists' aims could be seen to align with an "ethic of care" and were seen to be in tension in light of systemic constraints. The findings raise issues related to occupational justice, particularly related to occupational alienation in occupational therapy practice, and open conversations related to neoliberalist health care agendas. © The Author(s) 2016.

    1996-01-01

    We describe a Decision-supported Outpatient Practice (DOP) system developed and now in use at the Columbia-Presbyterian Medical Center. DOP is an automated ambulatory medical record system that integrates in-patient and ambulatory care data, and incorporates active and passive decision support mechanisms with a view towards improving the quality of primary care. Active decision support occurs in the form of event-driven reminders created within a remote clinical information system with its central data repository and decision support system (DSS). Novel features of DOP include patient specific health maintenance task lists calculated by the remote DSS. uses of a semantically structured controlled medical vocabulary to support clinical results review and provider data entry, and exploitation of an underlying ambulatory data model that provides for an explicit record of evolution of insight regarding patient management. Benefits, challenges, and plans are discussed. PMID:8947774

    Many problems encountered in general practice cannot be sufficiently explained within the Newtonian reductionist paradigm. Systems and complexity thinking - already widely adopted in most nonmedical disciplines - describes and explores the contextual nature of questions posed in medicine, and in general practice in particular. This article briefly describes the framework underpinning systems and complexity sciences. A case study illustrates how systems and complexity thinking can help to better understand the contextual nature of patient presentations, and how different approaches will lead to different outcomes.

    2008-01-01

    In 2007 the NESC completed an in-depth assessment to identify, define and document engineering considerations for the Design Development Test and Evaluation (DDT&E) of human-rated spacecraft systems. This study had been requested by the Astronaut Office at JSC to help them to better understand what is required to ensure safe, robust, and reliable human-rated spacecraft systems. The 22 GN&C engineering Best Practices described in this paper are a condensed version of what appears in the NESC Technical Report. These Best Practices cover a broad range from fundamental system architectural considerations to more specific aspects (e.g., stability margin recommendations) of GN&C system design and development. 15 of the Best Practices address the early phases of a GN&C System development project and the remaining 7 deal with the later phases. Some of these Best Practices will cross-over between both phases. We recognize that this set of GN&C Best Practices will not be universally applicable to all projects and mission applications.

    E-mail may rule the world in other types of businesses, but for medical practices, the telephone remains the primary mode of communication with patients, specialists, and pharmacies. From making appointments to calling in prescriptions, telephones are essential to patient care. With technology changing very quickly and new capabilities coming into the medical practice, such as telemedicine and Skype, you need to know your options when choosing a new telephone system. The possibilities include on-site, cloud, and hybrid networked solutions. A wide variety of features and capabilities are available, from dozens of vendors. Of course, no matter what telephone solution you choose, you must meet regulatory compliance, particularly HIPAA, and Payment Card Industry Data Security Standard if you take credit cards. And it has to be affordable, reliable, and long lasting. This article explores what medical practices need to know when choosing a new business telephone system in order to find the right solutions for their businesses.

    Purpose: We set out to create and evaluate a systems-based practice experience designed to introduce residents to front office responsibilities and stimulate suggestions for front office improvements. Methods: On two occasions in 2002 and 2006, each resident in the Obstetrics and Gynecology Department was trained by a front office staff member for one day. The residents completed pre- and post-experience surveys, answered open-ended questions about their experience, and volunteered suggestions for improving the front office staff, and were evaluated by their precepting staff member. Results: All but two of 23 particpating residents participated enthusiastically. These residents perceived experiencing the staff as vital to the success of the practice, reported an increased sense of appreciation for the training of staff personnel, and were evaluated favorably. Conclusion: This program gave our residents an appreciation for the training and responsibilities of pivotal office staff and an opportunity to suggest improvements. This program also satisfied ACGME resident education requirements regarding systems-based practice. PMID:20165536

    2003-04-01

    Diabetes is a self-managed disease for which patients provide 99% of their own care. For patients to succeed as diabetes self-managers, they need office practices and health care systems that can prepare and support them in their diabetes self-management efforts over the long term. In order to provide effective diabetes education and ongoing support, office practices and health care systems will have to fundamentally redefine the roles of health professionals and patients with diabetes, and redesign practices and systems to allow for effective long-term self-management education and support. Although it is difficult for both people and systems to change, change is essential if we are going to provide self-management support for the majority of patients suffering from this serious chronic disease.

    A nursing record system is the record of care that was planned or given to individual patients and clients by qualified nurses or other caregivers under the direction of a qualified nurse. Nursing record systems may be an effective way of influencing nurse practice. To assess the effects of nursing record systems on nursing practice and patient outcomes. For the original version of this review in 2000, and updates in 2003 and 2008, we searched: the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register; MEDLINE, EMBASE, CINAHL, BNI, ISI Web of Knowledge, and ASLIB Index of Theses. We also handsearched: Computers, Informatics, Nursing (Computers in Nursing); Information Technology in Nursing; and the Journal of Nursing Administration. For this update, searches can be considered complete until the end of 2007. We checked reference lists of retrieved articles and other related reviews. Randomised controlled trials (RCTs), controlled before and after studies, and interrupted time series comparing one kind of nursing record system with another in hospital, community or primary care settings. The participants were qualified nurses, students or healthcare assistants working under the direction of a qualified nurse, and patients receiving care recorded or planned using nursing record systems. Two review authors (in two pairs) independently assessed trial quality and extracted data. We included nine trials (eight RCTs, one controlled before and after study) involving 1846 people. The studies that evaluated nursing record systems focusing on relatively discrete and focused problems, for example effective pain management in children, empowering pregnant women and parents, reducing loss of notes, reducing time spent on data entry of test results, reducing transcription errors, and reducing the number of pieces of paper in a record, all demonstrated some degree of success in achieving the desired results. Studies of nursing care planning

    African consumers and citizens are growingly aware of the wide range of toxic poisoning scenarios from different products and hazards. Recurrent episodes on poisoning that have been reported in Africa include toxic hazards in consumers’ products ranging from food to herbal medicine, drugs, and cosmetics. Chemical poisoning remains an issue that is overlooked by public health stakeholders in Africa. Available information on toxicovigilance systems and practices in African countries is reviewed in terms of increasing development, organization and articulation levels. Less than nine out of 54 African countries have a legally recognized toxicovigilance system. Of these, the majority have created toxicovigilance systems recently, and are facing many challenges in developing them, at regional and country levels. Basic structures for a good toxicovigilance system include a phone line service (available 24/7), and hospital facilities. Pesticides emerge as the hazard recognized by all of the toxicovigilance systems, and may represent a prototypic toxicant towards a toxicovigilance system that is inclusive of a wider spectrum of toxicological hazards for the protection of community health. Toxicovigilance today is more reactive than preventive in Africa, but some milestones are present that constitute some promising seminal efforts. PMID:29051419

    2018-03-01

    The number of individuals with food allergies or intolerances attending catered university residential colleges is increasing, and safe dining options are required to minimize the risk of allergic reactions and food-induced death. This qualitative research study sought to advance professional knowledge of the factors affecting allergen management practices, particularly pertaining to college foodservices. Three catered residential colleges affiliated with a major university in New Zealand were selected as research sites. The study used an ethnographic approach and systems-practice theory as a framework for data collection and organizing results. Data collection techniques included document analyses (3 hours per site), observations (6 to 8 hours per site), focus groups with foodservice workers (30 to 45 minutes per site, n=16), and interviews with foodservice managers (45 to 90 minutes per interview, n=5). Notes and transcripts were coded through the process of thematic analysis using NVivo for Mac software, version 11.1.1, to identify factors affecting allergen management practices. The main factors affecting allergen management practices at college foodservices included information provided by residents about dietary requirements; communication between residents and foodservice staff; systems for allergen management; attitude of foodservice staff; and college size. Detailed dietary information, effective communication with residents, sufficient resources, clarification of responsibilities, and thorough systems are required for staff to perform safe allergen management practices. Ultimately, successful implementation was predominantly determined by staff attitude. Foodservice managers are advised to identify motivators and address barriers of staff attitudes toward allergen management practices to promote successful implementation.

Devices capable of managing an image viewer system without direct contact with equipment simplify working in the operating room. To test operation of a non-contact MRI and MSCT image viewer system in the operating room and to evaluate the system effectiveness. An Opect non-contact image management system developed at the Tokyo Women's Medical University was installed in one of the operating rooms of the Novosibirsk Federal Center of Neurosurgery in 2014. In 2015, the Opect system was used by operating surgeons in 73 surgeries performed in the same operating room. The system effectiveness was analyzed based on a survey of surgeons. The non-contact image viewer system occurred to be easy-to-learn for the personnel to operate this system, easy-to-manage it, and easy-to-present visual information during surgery. Application of the Opect system simplifies work with neuroimaging data during surgery. The surgeon can independently view series of relevant MRI and MSCT scans without any assistance.

    Resident education in Systems-Based Practice (SBP) and Practice-Based Learning and Improvement (PBLI) is required but underemphasized. The objectives are to identify SBP and PBLI knowledge and skills with the most relevance to our graduates' practices and to determine how well they were prepared during residency training to address these issues. A survey was drafted based on Accreditation Council for Graduate Medical Education competency definitions and published literature on SBP and PBLI. Respondents indicated the extent to which each item is relevant to their practice and the adequacy of instruction received on a 5-point Likert scale. All topics had high perceived relevance to practice with most topics rated low for adequacy of training. Topics of practice management and health care economics contained the largest gaps between mean ratings of relevance and adequacy of training (p < .001). Few differences in ratings were seen based on graduate demographics. This survey has allowed us to prioritize SBP and PBLI curricula to meet the needs of our graduates.

    Systems-Based Practice (SBP) is the sixth competency defined by the Accreditation Council for Graduate Medical Education (ACGME) Outcome Project. Specifically, SBP requires "Residents [to] demonstrate an awareness of and responsiveness to the larger context and system of health care and the ability to effectively call on system resources to provide care that is of optimal value." This competency can be divided into four subcompetencies, all of which are integral to training emergency medicine (EM) physicians: resources, providers, and systems; cost-appropriate care; delivery systems; and patient advocacy. In March 2002, the Council of Emergency Medicine Residency Directors (CORD-EM) convened a consensus conference to assist residency directors in modifying the SBP competency specific for EM. The Consensus Group modified the broad ACGME definition for SBP into EM-specific goals and objectives for residency training in SBP. The primary assessment methods from the Toolbox of Assessment Methods were also identified for SBP. They are direct observation, global ratings, 360-degree evaluations, portfolio assessment, and testing by both oral and written exams. The physician tasks from the Model of the Clinical Practice of Emergency Medicine that are most relevant to SBP are out-of-hospital care, modifying factors, legal/professional issues, diagnostic studies, consultation and disposition, prevention and education, multitasking, and team management. Suggested EM residency curriculum components for SBP are already in place in most residency programs, so no additional resources would be required for their implementation. These include: emergency medical services and administrative rotations, directed reading, various interdisciplinary and hospital committee participation, continuous quality improvement project participation, evidence-based medicine instruction, and various didactic experiences, including follow-up, interdisciplinary, and case conferences.

    Public health education is becoming an increasing priority among educators of medicine. In China, little attention has been paid to public health education reform. A new public health training system was introduced in China in 2007. We conducted this study during 2006-2012 to evaluate the graduate core competencies under the new system. Data were collected from 231 graduates and 49 public health agencies. The 144 graduates who enrolled in 2006 and were trained under the old system constituted the control group; the 87 graduates who enrolled in 2007 and were trained under the new system constituted the experimental group. Surveys of graduate core competencies found analyzing and solving problems in the laboratory, conducting on-site practice and learning new technologies were the top three abilities most expected by public health agencies. After 5-year practical ability training, the graduates in the experimental group had better performance; on-site practical ability and laboratory practical ability increased significantly by 24.5% and 20.0%, respectively. Three other important competencies also improved: designing epidemiologic surveys, collecting information from the literature and doing statistical analyses. However, preventing and controlling common diseases and dealing with emergencies remained weak. These results show the new training system should be continued, but revisions are needed to improve this training system, especially in the areas of preventing and controlling common diseases and dealing with emergencies.

    2017-09-15

    The unifying theme of the papers in this series is a concern for understanding the everyday practice of governance in low- and middle-income country (LMIC) health systems. Rather than seeing governance as a normative health system goal addressed through the architecture and design of accountability and regulatory frameworks, these papers provide insights into the real-world decision-making of health policy and system actors. Their multiple, routine decisions translate policy intentions into practice - and are filtered through relationships, underpinned by values and norms, influenced by organizational structures and resources, and embedded in historical and socio-political contexts. These decisions are also political acts - in that they influence who accesses benefits and whose voices are heard in decision-making, reinforcing or challenging existing institutional exclusion and power inequalities. In other words, the everyday practice of governance has direct impacts on health system equity.The papers in the series address governance through diverse health policy and system issues, consider actors located at multiple levels of the system and draw on multi-disciplinary perspectives. They present detailed examination of experiences in a range of African and Indian settings, led by authors who live and work in these settings. The overall purpose of the papers in this series is thus to provide an empirical and embedded research perspective on governance and equity in health systems.

    To determine how an enhanced early warning system has an impact on nursing practice. Early warning systems score physiologic measures and alert nurses to subtle changes in patient condition. Critics of early warning systems have expressed concern that nurses would rely on a score rather than assessment skills and critical thinking to determine the need for intervention. Enhancing early warning systems with innovative technology is still in its infancy, so the impact of an enhanced early warning system on nursing behaviours or practice has not yet been studied. Phenomenological design. Scripted, semistructured interviews were conducted in September 2015 with 25 medical/surgical nurses who used the enhanced early warning system. Data were analysed using thematic analysis techniques (coding and bracketing). Emerging themes were examined for relationships and a model describing the enhanced early warning system experience was developed. Nurses identified awareness leading to investigation and ease of prioritization as the enhanced early warning system's most important impact on their nursing practice. There was also an impact on organizational culture, with nurses reporting improved communication, increased collaboration, increased accountability and proactive responses to early changes in patient condition. Rather than hinder critical thinking, as many early warning systems' critics claim, nurses in this study found that the enhanced early warning system increased their awareness of changes in a patient's condition, resulting in earlier response and reassessment times. It also had an impact on the organization by improving communication and collaboration and supporting a culture of proactive rather than reactive response to early signs of deterioration. © 2017 John Wiley & Sons Ltd.

    This research explores the extent to which different farm management practices influence the perceived animal friendliness of broiler production systems, and how this differs between individuals. Using a conjoint design with paired comparisons, respondents evaluated broiler production systems that were described on the basis of 7 animal welfare-related practices. It was found that practices in the area of outdoor access, stocking density, and day-night rhythm were overall perceived to have a larger impact on perceptions of animal friendliness than other practices, such as transport duration or the type of breed used. However, individuals differed regarding the extent to which they believed the different farm management practices influenced the animal friendliness of the production system. Differences between individuals regarding their knowledge about and familiarity with livestock farming, degree of anthropomorphism, and their moral beliefs regarding animal welfare partly explained the relative importance individuals attached to farm management practices. The obtained insight into which welfare-related farm management practices, in consumers' minds, most strongly contribute to animal welfare, and the existence of differences between consumers, can be helpful in the development of animal welfare-based certification schemes that are appealing to consumers, as well as the positioning of welfare concepts in the market.

    Practical issues such as accuracy with various subjects, number of sensors, and time for training are important problems of existing brain-computer interface (BCI) systems. In this paper, we propose a hybrid framework for the BCI system that can make machine control more practical. The electrooculogram (EOG) is employed to control the machine in the left and right directions while the electroencephalogram (EEG) is employed to control the forword, no action, and complete stop motions of the machine. By using only 2-channel biosignals, the average classification accuracy of more than 95% can be achieved.

    2017-09-01

    The aim of this study was to explore health professionals' perceptions of an extended scope of a practice clinic, and develop a framework using a systems approach to facilitate extended scope models across various health settings. A qualitative investigation using semi-structured interviews with four health professionals involved in an extended scope dietitian-led gastroenterology clinic in a hospital in regional Queensland was conducted. A case study design was utilised to investigate interviewees' perceptions of the clinic. Participants were conveniently, purposively sampled. Transcript analysis involved a descriptive analytical approach. Interviewee responses were coded and categorised into themes, and investigator triangulation was used to ensure consistency between individual analyses. A secondary interpretative analysis was conducted where relationships between key themes were mapped to the Systems Engineering Initiative for Patient Safety work system model. Interviewees identified various factors as vital inputs to the work system. These were categorised into the four key elements: stakeholder support, resources, planning and the dietitian. Clinic outcomes were categorised into the impact on four key groups: patients, the dietitian, the multidisciplinary team and the health system. Mapping of the relationships between inputs and outcomes resulted in an implementation framework for extended scope of practice. Extended scope of practice in dietetics may provide positive outcomes for various stakeholders. However, further development of extended scope roles for dietitians requires increased advocacy and support from governments, professional bodies, training institutions and dietitians. We have developed an implementation framework which can be utilised by health professionals interested in embracing an extended scope model of care. © 2016 Dietitians Association of Australia.

    Increasing prominence is being given to the use of best current evidence in clinical practice and health services and programme management decision-making. The role of information in evidence-based practice (EBP) is discussed, together with questions of how advanced information systems and technology (IS&T) can contribute to the establishment of a broader perspective for EBP. The author examines the development, validation and use of a variety of sources of evidence and knowledge that go beyond the well-established paradigm of research, clinical trials, and systematic literature review. Opportunities and challenges in the implementation and use of IS&T and knowledge management tools are examined for six application areas: reference databases, contextual data, clinical data repositories, administrative data repositories, decision support software, and Internet-based interactive health information and communication. Computerized and telecommunications applications that support EBP follow a hierarchy in which systems, tasks and complexity range from reference retrieval and the processing of relatively routine transactions, to complex "data mining" and rule-driven decision support systems.

    To be consistent with IAU/IUGG (1991) resolutions ICRS and ITRS should be treated as four-dimensional reference systems with TCB and TCG time scales, respectively, interrelated by a four-dimensional general relativistic transformation. This two-way transformation is given in the form adapted for actual application. The use of TB and TT instead of TCB and TCG, respectively, involves scaling factors complicating the use of this transformation in practice. New IAU B1 (2000) resolution is commented taking in mind some points of possible confusion in its practical application. The problem of the relationship of the theory of reference systems with the parameters of common relevance to astronomy, geodesy and geodynamics is briefly outlined.

    We propose a practical system that can effectively mix the depth data of real and virtual objects by using a Z buffer and can quickly generate digital mixed reality video holograms by using multiple graphic processing units (GPUs). In an experiment, we verify that real objects and virtual objects can be merged naturally in free viewing angles, and the occlusion problem is well handled. Furthermore, we demonstrate that the proposed system can generate mixed reality video holograms at 7.6 frames per second. Finally, the system performance is objectively verified by users' subjective evaluations.

    Health systems science (HSS) is an emerging discipline addressing multiple, complex, interdependent variables that affect providers’ abilities to deliver patient care and influence population health. New perspectives and innovations are required as physician leaders and medical educators strive to accelerate changes in medical education and practice to meet the needs of evolving populations and systems. The purpose of this paper is to introduce gaming science as a lens to magnify HSS integration opportunities in the scope of medical education and practice. Evidence supports gaming science innovations as effective teaching and learning tools to promote learner engagement in scientific and systems thinking for decision making in complex scenarios. Valuable insights and lessons gained through the history of war games have resulted in strategic thinking to minimize risk and save lives. In health care, where decisions can affect patient and population outcomes, gaming science innovations have the potential to provide safe learning environments to practice crucial decision-making skills. Research of gaming science limitations, gaps, and strategies to maximize innovations to further advance HSS in medical education and practice is required. Gaming science holds promise to equip health care teams with HSS knowledge and skills required for transformative practice. The ultimate goals are to empower providers to work in complex systems to improve patient and population health outcomes and experiences, and to reduce costs and improve care team well-being.

    Organic farming system emphasises on sustainable development of agriculture. The traditional agriculture system was much akin to the organic system but modernization of agriculture made a shift to this trend. The north east region of India is potential organic farming sites. Most of the farming systems are traditional and are organic by default; however crops in organic farming are prone to many fungal diseases. Hence for validation of the impact of organic practices on the disease development of plants, a study has been conducted for three years under natural environmental conditions on bean rust (Uromyces appendiculatus). Study includes ecofriendly practices like: plant extract treatment, intercropping of beans with maize, organic manure application, influence of cropping season and Trichoderma treatment. Rust is a major prevalent disease in the cultivation of beans as in other parts of the world. Detailed study of the disease in the organic environment and the impact of various treatments and agricultural agronomic practices would help in validation of the practices for the management of the disease in the organic farming system. In our study for three consecutive years it has been revealed that the practices of the traditional farmers likeplant extract application, intercropping, and manure application were found to have significant positive effects in reducing rust development in the bean fields. The treatment of farm yard manure resulted in development of lesser area under disease progress curve. The plant extract of Artemisia vulgaris has marked positive impact on reducing rust disease parameters. Foliar application of Trichoderma reduces the disease parameters of rust. This study would enhance information in understanding the impact of organic farming system on bean rust and would help in validitation of sustainable agricultural practices for use in organic farming system.

    Approximately 1 in 3 US adults has hypertension, but only half have their blood pressure controlled. We identified characteristics of health care practices and systems (hereinafter practices) effective in achieving control rates at or above 70% by using data collected via applications submitted from April through June 2017 for consideration in the Million Hearts Hypertension Control Challenge. We included 96 practices serving 635,000 patients with hypertension across 34 US states in the analysis. Mean hypertension control rate was 77.1%; 27.1% of practices had a control rate of 80% or greater. Although many practices served large populations with multiple risk factors for uncontrolled hypertension, high control rates were achieved with implementation of evidenced-based strategies.

  1. MO-DE-BRA-02: From Teaching to Learning: Systems-Based-Practice and Practice-Based-Learning Innovations in Medical Physics Education Programs

    Kapur, A

    Purpose: The increasing complexity in the field of radiation medicine and concomitant rise in patient safety concerns call for enhanced systems-level training for future medical physicists and thus commensurate innovations in existing educational program curricula. In this work we report on the introduction of three learning opportunities to augment medical physics educational programs towards building systems-based practice and practice-based learning competencies. Methods: All initiatives were introduced for senior -level graduate students and physics residents in an institution with a newly established medical-physics graduate program and therapeutic-physics residency program. The first, centered on incident learning, was based on a spreadsheet toolmore » that incorporated the reporting structure of the Radiation Oncology-incident Learning System (ROILS), included 120 narratives of published incidents and enabled inter-rater variability calculations. The second, centered on best-practices, was a zero-credit seminar course, where students summarized select presentations from the AAPM virtual library on a weekly basis and moderated class discussions using a point/counterpoint approach. Presentation styles were critiqued. The third; centered on learning-by-teaching, required physics residents to regularly explain fundamental concepts in radiological physics from standard textbooks to board certified physics faculty members. Results: Use of the incident-learning system spreadsheet provided a platform to recast known accidents into the framework of ROILS, thereby increasing awareness of factors contributing to unsafe practice and appreciation for inter-rater variability. The seminar course enhanced awareness of best practices, the effectiveness of presentation styles and encouraged critical thinking. The learn-by-teaching rotation allowed residents to stay abreast of and deepen their knowledge of relevant subjects. Conclusion: The incorporation of systems

    This study introduces the Clinical practice guidelines (CPGs) appraisal system by the Korean Academy of Medical Sciences (KAMS). Quality management policies for CPGs vary among different countries, which have their own cultures and health care systems. However, supporting developers in guideline development and appraisals using standardized tools are common practices. KAMS, an organization representing the various medical societies of Korea, has been striving to establish a quality management system for CPGs, and has established a CPGs quality management system that reflects the characteristics of the Korean healthcare environment and the needs of its users. KAMS created a foundation for the development of CPGs, set up an independent appraisal organization, enacted regulations related to the appraisals, and trained appraisers. These efforts could enhance the ability of each individual medical society to develop CPGs, to increase the quality of the CPGs, and to ultimately improve the quality of the information available to decision-makers.

    To better prepare radiology residents for providing care within the context of the larger health care system, this study evaluated the feasibility and impact of a curriculum to enhance radiology residents' understanding and ability to apply concepts from medical management and industrial and operational engineering to systems-based practice problems in radiology practice. A multiprofessional team including radiology, medical education, and industrial and operational engineering professionals collaborated in developing a seven-module curriculum, including didactic lectures, interactive large-group analysis, and small-group discussions with case-based radiology examples, which illustrated real-life management issues and the roles physicians held. Residents and faculty participated in topic selection. Pre- and post-instruction formative assessments were administered, and results were shared with residents during teaching sessions. Attendance and participation in case-based scenario resolutions indicate the feasibility and impact of the interactive curriculum on residents' interest and ability to apply curricular concepts to systems-based practice in radiology. Paired t test analyses (P < .05) and effect sizes showed residents significantly increased their knowledge and ability to apply concepts to systems-based practice issues in radiology. Our iterative curriculum development and implementation process demonstrated need and support for a multiprofessional team approach to teach management and operational engineering concepts. Curriculum topics are congruent with Accreditation Council for Graduate Medical Education requirements for systems-based practice. The case-based curriculum using a mixed educational format of didactic lectures and small-group discussion and problem analysis could be adopted for other radiology programs, for both residents and continuing medical education applications.

    The aim of this study was to determine whether management system practices directed at both occupational health and safety (OHS) and operations (joint management system [JMS] practices) result in better outcomes in both areas than in alternative practices. Separate regressions were estimated for OHS and operational outcomes using data from a survey along with administrative records on injuries and illnesses. Organizations with JMS practices had better operational and safety outcomes than organizations without these practices. They had similar OHS outcomes as those with operations-weak practices, and in some cases, better outcomes than organizations with safety-weak practices. They had similar operational outcomes as those with safety-weak practices, and better outcomes than those with operations-weak practices. Safety and operations appear complementary in organizations with JMS practices in that there is no penalty for either safety or operational outcomes.

  6. Complex adaptive systems: A new approach for understanding health practices.

    PubMed

    Gomersall, Tim

    2018-06-22

    This article explores the potential of complex adaptive systems theory to inform behaviour change research. A complex adaptive system describes a collection of heterogeneous agents interacting within a particular context, adapting to each other's actions. In practical terms, this implies that behaviour change is 1) socially and culturally situated; 2) highly sensitive to small baseline differences in individuals, groups, and intervention components; and 3) determined by multiple components interacting "chaotically". Two approaches to studying complex adaptive systems are briefly reviewed. Agent-based modelling is a computer simulation technique that allows researchers to investigate "what if" questions in a virtual environment. Applied qualitative research techniques, on the other hand, offer a way to examine what happens when an intervention is pursued in real-time, and to identify the sorts of rules and assumptions governing social action. Although these represent very different approaches to complexity, there may be scope for mixing these methods - for example, by grounding models in insights derived from qualitative fieldwork. Finally, I will argue that the concept of complex adaptive systems offers one opportunity to gain a deepened understanding of health-related practices, and to examine the social psychological processes that produce health-promoting or damaging actions.

    To describe the strategy employed by Andalusian public health service hospitals to foster safe medication use. The self-evaluation questionnaire on drug system safety in hospitals, adapted by the Spanish Institute for Safe Medication Practices was used as a fundamental tool to that end. The strategy is developed in several phases. We analyse the report evaluating drug system safety in Andalusian public hospitals published by the Spanish Ministry of Health and Consumption in 2008 and establish a grading system to assess safe medication practices in Andalusian hospitals and prioritise areas needing improvement. We developed a catalogue of best practices available in the web environment belonging to the Andalusian health care quality agency's patient safety observatory. We publicised the strategy through training seminars and implemented a system allowing hospitals to evaluate the degree of compliance for each of the best practices, and based on that system, we were able to draw up a map of centres of reference. We found areas for improvement among several of the questionnaire's fundamental criteria. These areas for improvement were related to normal medication procedures in daily clinical practice. We therefore wrote 7 best practice guides that provide a cross-section of the assessment components of the questionnaire related to the clinical process needing improvement. The self-evaluation questionnaire adapted by ISMP-Spain is a good tool for designing a systematic, rational intervention to promote safe medication practices and intended for a group of hospitals that share the same values.

    Background Computerized reminder systems (CRS) show promise for increasing preventive services such as colorectal cancer (CRC) screening. However, prior research has not evaluated a generalizable CRS across diverse, community primary care practices. We evaluated whether a generalizable CRS, ClinfoTracker, could improve screening rates for CRC in diverse primary care practices. Methods The study was a prospective trial to evaluate ClinfoTracker using historical control data in 12 Great Lakes Research In Practice Network community-based, primary care practices distributed from Southeast to Upper Peninsula Michigan. Our outcome measures were pre- and post-study practice-level CRC screening rates among patients seen during the 9-month study period. Ability to maintain the CRS was measured by days of reminder printing. Field notes were used to examine each practice’s cohesion and technology capabilities. Results All but one practice increased their CRC screening rates, ranging from 3.3% to 16.8% improvement. t tests adjusted for within practice correlation showed improvement in screening rates across all 12 practices, from 41.7% to 50.9%, P = 0.002. Technology capabilities impacted printing days (74% for high technology vs. 45% for low technology practices, P = 0.01), and cohesion demonstrated an impact trend for screening (15.3% rate change for high cohesion vs. 7.9% for low cohesion practices). Conclusions Implementing a generalizable CRS in diverse primary care practices yielded significant improvements in CRC screening rates. Technology capabilities are important in maintaining the system, but practice cohesion may have a greater influence on screening rates. This work has important implications for practices implementing reminder systems. PMID:18725836

    Health policy and systems research (HPSR) is a transdisciplinary field of global importance, with its own emerging standards for creating, evaluating, and utilizing knowledge, and distinguished by a particular orientation towards influencing policy and wider action to strengthen health systems. In this commentary, we argue that the ability of the HPSR field to influence real world change hinges on its becoming more people-centred. We see people-centredness as recognizing the field of enquiry as one of social construction, requiring those conducting HPSR to locate their own position in the system, and conduct and publish research in a manner that foregrounds human agency attributes and values, and is acutely attentive to policy context. Change occurs at many layers of a health system, shaped by social, political, and economic forces, and brought about by different groups of people who make up the system, including service users and communities. The seeds of transformative practice in HPSR lie in amplifying the breadth and depth of dialogue across health system actors in the conduct of research - recognizing that these actors are all generators, sources, and users of knowledge about the system. While building such a dialogic practice, those conducting HPSR must strive to protect the autonomy and integrity of their ideas and actions, and also clearly explain their own positions and the value-basis of their work. We conclude with a set of questions that health policy and systems researchers may wish to consider in making their practice more people-centred, and hence more oriented toward real-world change.

    A nursing record system is the record of care planned and/or given to individual patients/clients by qualified nurses or other caregivers under the direction of a qualified nurse. Nursing record systems may be an effective way of influencing nurse practice. To assess the effects of nursing record systems on nursing practice and patient outcomes. We searched The Cochrane Library, MEDLINE, Cinahl, Sigle, and databases of the Royal College of Nursing, King's Fund, the NHS Centre for Reviews and Dissemination, and the Institute of Electrical Engineers up to August 1999; and OCLC First Search, Department of Health database, NHS Register of Computer Applications and the Health Visitors' Association database up to the end of 1995. We hand searched the Journal of Nursing Administration (1971-1999), Computers in Nursing (1984-1999), Information Technology in Nursing (1989-1999) and reference lists of articles. We also hand searched the major health informatics conference proceedings. We contacted experts in the field of nursing informatics, suppliers of nursing computer systems, and relevant Internet groups. Randomised trials, controlled before and after studies and interrupted time series comparing one kind of nursing record system with another, in hospital, community or primary care settings. The participants were qualified nurses, students or health care assistants working under the direction of a qualified nurse and patients receiving care recorded and/or planned using nursing record systems. Two reviewers independently assessed trial quality and extracted data. Six trials involving 1407 people were included. In three studies of client held records, there were no overall positive or negative effects, although some administrative benefits through fewer missing notes were suggested. A paediatric pain management sheet study showed a positive effect on the children's pain intensity. A computerised nursing care planning study showed a negative effect on documented nursing

    The definition of the fiscal unit/family structure has enabled users of the FMIS, or family practices in Colorado and Wyoming, to maintain accurate, ongoing financial information on their patients. In turn, this structure has been a major incentive for maintaining accurate family information, and a distinct benefit to FMIS users. This article has presented the rationale, design, and method of implementation of the fiscal unit structure, with the intention of presenting this concept to others for use in other information systems used in maintaining family-oriented financial and medical information for medical practices.

    This article examines the use of an integrated performance measurement system to plan and control primary care service delivery within an integrated delivery system. We review a growing body of literature that focuses on the development and implementation of management reporting systems among healthcare providers. Our study extends the existing literature by examining the use of performance information generated by an integrated performance measurement system within a healthcare organization. We conduct our examination through a case study of the WMG Primary Care Medicine Group, the primary care medical group practice of WellSpan Health System. WellSpan Health System is an integrated delivery system that serves south central Pennsylvania and northern Maryland. Our study examines the linkage between WellSpan Health's strategic objectives and its primary care medicine group's integrated performance measurement system. The conceptual design of this integrated performance measurement system combines financial metrics with practice management and clinical operating metrics to provide a more complete picture of medical group performance. Our findings demonstrate that WellSpan Health was able to achieve superior financial results despite a weak linkage between its integrated performance measurement system and its strategic objectives. WellSpan Health achieved this objective for its primary care medicine group by linking clinical performance information to physician compensation and reporting practice management performance through the use of statistical process charts. They found that the combined mechanisms of integrated performance measurement and statistical process control charts improved organizational learning and communications between organizational stakeholders.

  14. The future of health-system pharmacy: opportunities and challenges in practice model change.

    PubMed

    Zellmer, William A

    2012-04-01

    Key factors outside of health-system pharmacy that will shape this sector of the profession in the coming years are (1) the national economy, (2) national politics, (3) the debt of the federal government, (4) global megatrends (including terrorism and economic globalization), (5) health care reform, and (6) trends in the development and use of medicines. These factors will translate into payment cutbacks to hospitals, expanded mandates to improve the quality of health care, increased focus on patient-centered care, more team-based care, and a higher degree of integration across the range of health care settings and providers. In this environment, pharmacists in hospitals and other health systems will have rich opportunities to help improve patient care and institutional sustainability by continuing to move from order-fulfillment and product-preparation functions toward team leadership of drug therapy management. The American Society of Health-System Pharmacists Pharmacy Practice Model Initiative (PPMI) was created to encourage hospital and health-system practice leaders to examine how they deploy their resources (ie, pharmacist time, technician time, and technology) to ensure that the efforts of the pharmacy department are aligned with the most urgent needs of patients and institutions. Key recommendations of the PPMI and evidence about gaps in the provision of drug therapy management services are presented. It is important for every pharmacist and pharmacy technician in health-system practice to understand the imperatives for changing the profession's practice model and to actively pursue appropriate changes in that model.

    2004-01-01

    Practice-based learning and improvement (PBLI) and systems-based practice (SBP) may be conceptually difficult for both residents and faculty. Methods for introducing these concepts are needed if PBLI and SBP are to be incorporated into education and practice. In 2001, PBLI and SBP were introduced at Johns Hopkins Bayview Medical Center in Baltimore, Maryland, using the metaphors "the mirror" and "the village." PBLI was likened to residents' holding up a mirror to document, assess, and improve their practice. Specific tools for residents (e.g., weekly morbidity and mortality morning reports, continuity clinic chart self-audits, and resident learning portfolios) became the mirrors. SBP was introduced through specific training activities (e.g., multidisciplinary patient care rounds, nursing evaluations, and quality assessment-systems improvement exercises) using the metaphor of the village made famous by Hillary Clinton in the phrase: "It takes a village to raise a child." Residents completed a questionnaire in which they rated these initiatives' impact on their training. The majority of residents who participated in specific activities agreed that quality assessment-systems improvement exercises (92.9%), multidisciplinary rounds (92.1%), morbidity and mortality morning reports (86.8%), clinic chart self-audits (76.4%), and nursing evaluations (52.8%) helped to improve their proficiency in specific aspects of PBLI and SBP. Residents' retrospective self-assessments of their PBLI abilities demonstrated significant improvement after the introduction of specific training activities. PBLI and SBP can be introduced effectively in residency training by incorporating specific activities that use the metaphors of the mirror and the village.

  16. Practical considerations for a second-order directional hearing aid microphone system

    NASA Astrophysics Data System (ADS)

    Thompson, Stephen C.

    2003-04-01

    First-order directional microphone systems for hearing aids have been available for several years. Such a system uses two microphones and has a theoretical maximum free-field directivity index (DI) of 6.0 dB. A second-order microphone system using three microphones could provide a theoretical increase in free-field DI to 9.5 dB. These theoretical maximum DI values assume that the microphones have exactly matched sensitivities at all frequencies of interest. In practice, the individual microphones in the hearing aid always have slightly different sensitivities. For the small microphone separation necessary to fit in a hearing aid, these sensitivity matching errors degrade the directivity from the theoretical values, especially at low frequencies. This paper shows that, for first-order systems the directivity degradation due to sensitivity errors is relatively small. However, for second-order systems with practical microphone sensitivity matching specifications, the directivity degradation below 1 kHz is not tolerable. A hybrid order directive system is proposed that uses first-order processing at low frequencies and second-order directive processing at higher frequencies. This hybrid system is suggested as an alternative that could provide improved directivity index in the frequency regions that are important to speech intelligibility.

    2011-04-01

    Since 2001, residencies have struggled with teaching and assessing systems-based practice (SBP). One major obstacle may be that the competency alone is not sufficient to support assessment. We believe the foundational construct underlying SBP is systems thinking, absent from the current Accreditation Council for Graduate Medical Education competency language. Systems thinking is defined as the ability to analyze systems as a whole. The purpose of this article is to describe psychometric issues that constrain assessment of SBP and elucidate the role of systems thinking in teaching and assessing SBP. Residency programs should incorporate systems thinking models into their curricula. Trainees should be taught to understand systems at an abstract level, in order to analyze their own healthcare systems, and participate in quality and patient safety activities. We suggest that a developmental trajectory for systems thinking be developed, similar to the model described by Dreyfus and Dreyfus.

    Poor information quality (IQ) must be understood as a business problem rather than systems problem. In health care organization, what is required is an effective quality management that continuously manages and reviews the factors influencing IQ in health information systems (HIS) so as to achieve the desired outcomes. Hence, in order to understand the issues of information quality management (IQM) practices in health care organizations, a more holistic evaluation study should be undertaken to investigate the IQM practices in health care organizations. It is the aim of this paper to identify the significant evaluation criteria that influence the production of good IQ in HIS. Six selected frameworks and best practices both from health informatics and information systems literature have been reviewed to identify the evaluation criteria from the perspective of human, organizational and technological factors. From the review, it was found that human and organization factors are of greater significance in influencing HIS IQ. Our review depicts that there is still shortage in finding a comprehensive IQM evaluation framework. Thus, the criteria from the frameworks reviewed can be used in combination for more comprehensive evaluation criteria. Integrated IQM evaluation criteria for HIS are then proposed in this study. Poor IQ is the result of complex interdependency within sociotechnical factors in health care organization and lack of formal and structured IQM practices. Thus, a feedback mechanism such as evaluation is needed to understand the issues in depth in the future. © 2012 Blackwell Publishing Ltd.

    It has been demonstrated that electronic patient registries combined with a clinical decision support system have a significant positive impact on the documentation and delivery of services provided by health care professionals. While implementation of available commercial systems has not always been proven effective in a number of primary care practices, development and implementation of such a system in a practice-based research network might enhance successful implementation. Physicians in our practice-based research network (Oklahoma Physicians Resource/Research Network) initiated a project that aimed at designing, testing, and implementing a personal digital assistant-based diabetes management system. We utilized the "best practice" approach to determine the principles on which the application must operate. System development and beta testing were also accomplished based on the direct feedback of user clinicians. Practice Enhancement Assistants (PEAs) were available in the practices for assistance with implementation. Implementation of the Diabetes Patient Tracker (DPT) resulted in a significant improvement (p<0.05) in nine of 10 diabetic quality of care measures compared with pre-intervention levels in 20 primary care practices. Regular PEA visits similarly increased the number of foot exams and retinal exams performed in the last year (p=0.03 and 0.02, respectively). DPT is a low-cost, feasible, easily implementable, and very effective paper-less tool that significantly improves patient care and documentation in primary care practices.

    To evaluate the utility of Isabel, an online diagnostic decision support system developed by Isabel Healthcare primarily for secondary medical care, in the general practice setting. Focus groups were conducted with clinicians to understand why and how they used the system. A modified online post-use survey asked practitioners about its impact on their decision-making. Normalization process theory (NPT) was used as a theoretical framework to determine whether the system could be incorporated into routine clinical practice. The system was introduced by NHS County Durham and Darlington in the UK in selected general practices as a three-month pilot. General practitioners and nurse practitioners who had access to Isabel as part of the Primary Care Trust's pilot. General practitioners' views, experiences and usage of the system. Seven general practices agreed to pilot Isabel. Two practices did not subsequently use it. The remaining five practices conducted searches on 16 patients. Post-use surveys (n = 10) indicated that Isabel had little impact on diagnostic decision-making. Focus group participants stated that, although the diagnoses produced by Isabel in general did not have an impact on their decision-making, they would find the tool useful if it were better tailored to the primary care setting. Our analysis concluded that normalization was not likely to occur in its current form. Isabel was of limited utility in this short pilot study and may need further modification for use in general practice.

    Translating evidence into clinical practice is a complex process that depends on the availability of evidence, the environment into which the research evidence is translated, and the system that facilitates the translation. This paper presents InfoBot, a system designed for automatic delivery of patient-specific information from evidence-based resources. A prototype system has been implemented to support development of individualized patient care plans. The prototype explores possibilities to automatically extract patients problems from the interdisciplinary team notes and query evidence-based resources using the extracted terms. Using 4,335 de-identified interdisciplinary team notes for 525 patients, the system automatically extracted biomedical terminology from 4,219 notes and linked resources to 260 patient records. Sixty of those records (15 each for Pediatrics, Oncology & Hematology, Medical & Surgical, and Behavioral Health units) have been selected for an ongoing evaluation of the quality of automatically proactively delivered evidence and its usefulness in development of care plans.

    Physician practice management companies (PPMCs) are one of the most visible entrants into the industry of managing physician practices, and anywhere from 100-150 are already in operation. Although PPMCs and hospital-based integrated delivery systems (IDSs) differ from each other in many ways, they share a number of common features, including the pursuit of capitation contracts from payors. As a result, PPMCs pose a growing, direct threat to hospital systems in competing for managed care contracts that cover physician service. PPMCs also provide an alternative to hospital-based IDSs at the local market level for physician group consolidation. This article looks at the structure, operation, and strategy of PPMCs and examines what implications their growth will have for hospital-based IDSs.

    Over the past decade, the federal government has mandated healthcare providers to incorporate electronic health records into practice by 2015. This technological update in healthcare documentation has generated a need for advanced practice RN programs to incorporate information technology into education. The National Organization of Nurse Practitioner Faculties created core competencies to guide program standards for advanced practice RN education. One core competency is Technology and Information Literacy. Educational programs are moving toward the utilization of electronic clinical tracking systems to capture students' clinical encounter data. The purpose of this integrative review was to evaluate current research on advanced practice RN students' documentation of clinical encounters utilizing electronic clinical tracking systems to meet advanced practice RN curriculum outcome goals in information technology as defined by the National Organization of Nurse Practitioner Faculties. The state of the science depicts student' and faculty attitudes, preferences, opinions, and data collections of students' clinical encounters. Although electronic clinical tracking systems were utilized to track students' clinical encounters, these systems have not been evaluated for meeting information technology core competency standards. Educational programs are utilizing electronic clinical tracking systems with limited evidence-based literature evaluating the ability of these systems to meet the core competencies in advanced practice RN programs.

    The Accreditation Council for Graduate Medical Education (ACGME) initiated its Outcome Project to better prepare physicians-in-training to practice in the rapidly changing medical environment and mandated assessment of competency in six outcomes, including Practice-Based Learning and Improvement (PBLI) and Systems-Based Practice (SBP). Before the initiation of the Outcome Project, these competencies were not an explicit element of most graduate medical education training programs. Since 1999, directors of ACGME-accredited programs nationwide have been challenged to teach and assess these competencies. The authors describe an institution-wide curriculum intended to facilitate the teaching and assessment of PBLI and SBP competencies in the 115 ACGME-accredited residency and fellowship programs (serving 1,327 trainees) sponsored by Mayo School of Graduate Medical Education. Strategies to establish the curriculum in 2005 included development of a Quality Improvement (QI) curriculum Web site, one-on-one consultations with program directors, a three-hour program director workshop, and didactic sessions for residents and fellows on core topics. An interim program director self-assessment survey revealed a 13% increase in perceived ability to measure competency in SBP, no change in their perceived ability to measure competence in PBLI, a 15% increase in their ability to provide written documentation of competence in PBLI, and a 35% increase in their ability to provide written documentation of competence in SBP between 2005 and 2007. Nearly 70% of the programs had trainees participating in QI projects. Further research is needed to evaluate the cost-effectiveness of such a program and to measure its impact on learner knowledge, skills, and attitudes and, ultimately, on patient outcomes.

    A nursing record system is the record of care planned and/or given to individual patients/clients by qualified nurses or other caregivers under the direction of a qualified nurse. Nursing record systems may be an effective way of influencing nurse practice. To assess the effects of nursing record systems on nursing practice and patient outcomes. We searched The Cochrane Library, the EPOC trial register (October 2002), MEDLINE, Cinahl, Sigle, and databases of the Royal College of Nursing, King's Fund, the NHS Centre for Reviews and Dissemination, and the Institute of Electrical Engineers up to August 1999; and OCLC First Search, Department of Health database, NHS Register of Computer Applications and the Health Visitors' Association database up to the end of 1995. We hand searched the Journal of Nursing Administration (1971-1999), Computers in Nursing (1984-1999), Information Technology in Nursing (1989-1999) and reference lists of articles. We also hand searched the major health informatics conference proceedings. We contacted experts in the field of nursing informatics, suppliers of nursing computer systems, and relevant Internet groups. To update the review the Medline, Cinahl, British Nursing Index, Aslib Index to Theses databases were all searched from 1998 to 2002. The Journal of Nursing Administration, Computers in Nursing, Information Technology in Nursing were all hand searched up to 2002. The searches of the other databases and grey literature included in the original review, were not updated (except for Health Care Computing Conference and Med Info) as the original searches produced little relevant material. Randomised trials, controlled before and after studies and interrupted time series comparing one kind of nursing record system with another, in hospital, community or primary care settings. The participants were qualified nurses, students or health care assistants working under the direction of a qualified nurse and patients receiving care recorded

    All accredited US residency programs are expected to offer curricula and evaluate their residents in 6 general competencies. Medical schools are now adopting similar competency frameworks. We investigated whether a Web-based program could effectively teach and assess elements of systems-based practice. We enrolled 276 medical students and 417 residents in the fields of surgery, medicine, obstetrics-gynecology, and emergency medicine in a 9-week randomized, controlled, crossover educational trial. Participants were asked to sequentially complete validated Web-based modules on patient safety and the US health care system. The primary outcome measure was performance on a 26-item validated online test administered before, between, and after the participants completed the modules. Six hundred forty (92.4%) of the 693 enrollees participated in the study; 512 (80.0%) of the participants completed all 3 tests. Participants' test scores improved significantly after completion of the first module (P<.001). Overall learning from the 9-week Web-based program, as measured by the increase in scores (posttest scores minus pretest scores), was 16 percentage points (95% confidence interval, 14-17 percentage points; P<.001) in public safety topics and 22 percentage points (95% confidence interval, 20-23 percentage points; P<.001) in US health care system topics. A Web-based educational program on systems-based practice competencies generated significant and durable learning across a broad range of medical students and residents.

    Measurement of stress and strain in rotating turbomachinery is critical to many industries. The search for a non-contacting, non-interfering, non-degrading measurement system is on going and extensive. While several methods seem promising in theory, implementation has proven troublesome. This work uncovers and quantifies these implementation issues in the context of a laser measurement system. Both a Laser Doppler Velocimeter system and a displacement laser system are utilized. It is found that the key issues are signal to noise ratio, rigid body compensation, measurement location, and conversion of intermittent measurements to a continuous signal. Accounting for these factors leads to successful measurements. These results should lead to better ideas and more practical solutions to the non-contacting, non-degrading, non-interfering strain measurement system problem.

  18. Using Gunshot Detection Systems to Fight Explosive Fishing Practices

    Blast fishing (using explosives to catch fish) causes extensive damage to coral reefs, especially in the Coral Triangle in Southeast Asia. Subsistence fishermen and larger consortiums, often with criminal links, throw an explosive into a school of fish, killing all sea life within range. This unsustainable practice is becoming more prevalent, and threatens the protein supply of as many as a billion people. Ending blast fishing will require combined technical and societal methods aimed at both deterring the practice, and catching those responsible. Our work aims to significantly improve enforcement. We are re-purposing SST's ShotSpotter gunshot detection system, (trusted and valued by police around the world), substituting hydrophones for the present microphones. Using multilateration and trained human reviewers, the system can give prompt blast alerts, location data, and acoustic waveforms to law enforcement officials. We hope to establish a prototype system in Malaysia in 2015, and have already secured governmental approvals for installation and tests with local law enforcement. The Scubazoo media firm in Malaysia is working with resorts, dive operations, and celebrity sponsors, and is planning to produce videos to illustrate the severity of the problem to both governments and the public. Because there is little hard data concerning the prevalence of blast fishing in either marine protected areas or open waters, the system can also indicate to the world the actual blast rates and patterns of use. The Teng Hoi environmental NGO in Hong Kong showed in 2004 that acoustic waves from typical bombs propagate on the order of 20 km, so an underwater locator system with a small number of sensors can feasibly cover a sizable coral region. Our present plans are to mount sensors on piers, buoys, and boats, but if possible we would also like to integrate with other existing acoustic arrays to strengthen the fight against blast fishing.

    Public aquaria evaluate coliform indicator bacteria levels in fish systems, but the purpose of testing, testing methods, and management responses are not standardized, unlike with the coliform bacteria testing for marine mammal enclosures required by the U.S. Department of Agriculture. An online survey was sent to selected aquaria to document current testing and management practices in fish systems without marine mammals. The information collected included indicator bacteria species, the size and type of systems monitored, the primary purpose of testing, sampling frequency, test methods, the criteria for interpreting results, corrective actions, and management changes to limit human exposure. Of the 25 institutions to which surveys were sent, 19 (76%) responded. Fourteen reported testing for fecal indicator bacteria in fish systems. The most commonly tested indicator species were total (86%) and fecal (79%) coliform bacteria, which were detected by means of the membrane filtration method (64%). Multiple types and sizes of systems were tested, and the guidelines for testing and corrective actions were highly variable. Only three institutions performed additional tests to confirm the identification of indicator organisms. The results from this study can be used to compare bacterial monitoring practices and protocols in fish systems, as an aid to discussions relating to the accuracy and reliability of test results, and to help implement appropriate management responses.

    It is well known that the unconditional security of quantum-key distribution (QKD) can be guaranteed by quantum mechanics. However, practical QKD systems have some imperfections, which can be controlled by the eavesdropper to attack the secret key. With current experimental technology, a realistic beam splitter, made by fused biconical technology, has a wavelength-dependent property. Based on this fatal security loophole, we propose a wavelength-dependent attacking protocol, which can be applied to all practical QKD systems with passive state modulation. Moreover, we experimentally attack a practical polarization encoding QKD system to obtain all the secret key information at the cost ofmore » only increasing the quantum bit error rate from 1.3 to 1.4%.« less

In this paper we first consider the cognitive, cyber-physical interdependencies inherent in critical infrastructure systems and how resilience differs from reliability to mitigate these risks. Terminology and metrics basis are provided to integrate the cognitive, cyber-physical aspects that should be considered when defining solutions for resilience. A practical approach is taken to roll this metrics basis up to system integrity and business case metrics that establish “proper operation” and “impact.” A notional chemical processing plant is the use case for demonstrating how the system integritymore » metrics can be applied to establish performance, and« less

  4. Does an activity based remuneration system attract young doctors to general practice?

    PubMed Central

    2012-01-01

    Background The use of increasingly complex payment schemes in primary care may represent a barrier to recruiting general practitioners (GP). The existing Norwegian remuneration system is fully activity based - 2/3 fee-for-service and 1/3 capitation. Given that the system has been designed and revised in close collaborations with the medical association, it is likely to correspond - at least to some degree - with the preferences of current GPs (men in majority). The objective of this paper was to study which preferences that young doctors (women in majority), who are the potential entrants to general practice have for activity based vs. salary based payment systems. Methods In November-December 2010 all last year medical students and all interns in Norway (n = 1.562) were invited to participate in an online survey. The respondents were asked their opinion on systems of remuneration for GPs; inclination to work as a GP; risk attitude; income preferences; work pace tolerance. The data was analysed using one-way ANOVA and multinomial logistic regression analysis. Results A total of 831 (53%) responded. Nearly half the sample (47%) did not consider the remuneration system to be important for their inclination to work as GP; 36% considered the current system to make general practice more attractive, while 17% considered it to make general practice less attractive. Those who are attracted by the existing system were men and those who think high income is important, while those who are deterred by the system are risk averse and less happy with a high work pace. On the question of preferred remuneration system, half the sample preferred a mix of salary and activity based remuneration (the median respondent would prefer a 50/50 mix). Only 20% preferred a fully activity based system like the existing one. A salary system was preferred by women, and those less concerned with high income, while a fully activity based system was preferred by men, and those happy with a high work

    The environmental impact of the so-called conventional farming system calls for new farming practices reducing negative externalities. Emerging farming practices such as no-till and new inter-cropping management are promising tracks. The development of methods to characterize crop management across an entire region and to understand their spatial dimension offers opportunities to accompany the transition towards a more sustainable agriculture.This research takes advantage of the unmatched polarimetric and temporal resolutions of Sentinel-1 SAR C- band to develop a method to identify farming practices at the parcel level. To this end, the detection of changes in backscattering due to surface roughness modification (tillage, inter-crop cover destruction ...) is used to detect the farming management. The final results are compared to a reference dataset collected through an intensive field campaign. Finally, the performances are discussed in the perspective of practices monitoring of cropping systems through remote sensing.

  7. Risk Modeling of Interdependent Complex Systems of Systems: Theory and Practice.

    PubMed

    Haimes, Yacov Y

    2018-01-01

    The emergence of the complexity characterizing our systems of systems (SoS) requires a reevaluation of the way we model, assess, manage, communicate, and analyze the risk thereto. Current models for risk analysis of emergent complex SoS are insufficient because too often they rely on the same risk functions and models used for single systems. These models commonly fail to incorporate the complexity derived from the networks of interdependencies and interconnectedness (I-I) characterizing SoS. There is a need to reevaluate currently practiced risk analysis to respond to this reality by examining, and thus comprehending, what makes emergent SoS complex. The key to evaluating the risk to SoS lies in understanding the genesis of characterizing I-I of systems manifested through shared states and other essential entities within and among the systems that constitute SoS. The term "essential entities" includes shared decisions, resources, functions, policies, decisionmakers, stakeholders, organizational setups, and others. This undertaking can be accomplished by building on state-space theory, which is fundamental to systems engineering and process control. This article presents a theoretical and analytical framework for modeling the risk to SoS with two case studies performed with the MITRE Corporation and demonstrates the pivotal contributions made by shared states and other essential entities to modeling and analysis of the risk to complex SoS. A third case study highlights the multifarious representations of SoS, which require harmonizing the risk analysis process currently applied to single systems when applied to complex SoS. © 2017 Society for Risk Analysis.

    The Accreditation Council for Graduate Medical Education (ACGME) requires that training programs integrate system-based practice (SBP) and practice-based learning and improvement (PBLI) into internal medicine residency curricula. CONTEXT AND SETTING: We instituted a seminar series and year-long-mentored curriculum designed to engage internal medicine residents in these competencies. Residents participate in a seminar series that includes assigned reading and structured discussion with faculty who assist in the development of quality improvement or research projects. Residents pursue projects over the remainder of the year. Monthly works in progress meetings, protected time for inquiry, and continued faculty mentorship guide the residents in their project development. Trainees present their work at hospital-wide grand rounds at the end of the academic year. We performed a survey of residents to assess their self-reported knowledge, attitudes and skills in SBP and PBLI. In addition, blinded faculty scored projects for appropriateness, impact, and feasibility. We measured resident self-reported knowledge, attitudes, and skills at the end of the academic year. We found evidence that participants improved their understanding of the context in which they were practicing, and that their ability to engage in quality improvement projects increased. Blinded faculty reviewers favorably ranked the projects' feasibility, impact, and appropriateness. The 'Curriculum of Inquiry' generated 11 quality improvement and research projects during the study period. Barriers to the ongoing work include a limited supply of mentors and delays due to Institutional Review Board approval. Hospital leadership recognizes the importance of the curriculum, and our accreditation manager now cites our ongoing work.

    Blackmore, Chris

    The Open University course that prompted this book, and for which it is part of the required reading, focuses on managing systemic change. The course is designed for people who want to develop their skills and understanding in systems thinking and practice, to be used in a range of different domains. Most of the examples in the course come from work-based settings. The idea of managing in this context is mainly about appreciating situations with others, recognising what actions are desirable and feasible and for whom, and getting organised, in order to affect or respond to change in a positive way. It has little to do with control. As Vickers (1978, p. 81) said 'I do not think it too much to hope that an understanding of systemic relations may bring us a better understanding of our limitations and even our possibilities.'

    2010-01-01

    In this chapter, the recent advancements and practical aspects of laser SRS diagnostics have been reviewed wi til regards to applications in practical combustion systems. Clearly, SRS represents a theoretically and experimentally mature diagnostic technology that has become an essential tool for multiscalar measurements in turbulent combustion at elevated pressures. Today, time-, space-, spectrally, and even polarization-resolved S RS diagnostics is at hand, with aid from recent innovations in theoretical and technological developments on electro-optical or electromechanical devices. Whilst a linear increase in SRS signals can be expected in high-pressure systems (this is perhaps one of the most important advantages for using SRS in high-pressure systems), there are practical (often severe) restrictions associated with pressurized vessels, due mainly to the limited degree of optical access. This narrows ti,e available choice of diagnostics that can be employed at any given time. Point-wise SRS diagnostics provides the highest accuracy on the chemical species and temperature measurements, and will continue to remain a vital approach for the study in such harsh environments. The practical design considerations and hands-on set-up guide for SRS diagnostics provided in this chapter are rarely presented elsewhere. Although the second-harmonic Nd:YAG pulsed laser (532 nm), combined with pulse-stretching optics or the recently introduced White Cell-based laser, seems to be the most favored excitation source of choice by the research community, UV excitation will undoubtedly continue to be used on many occasions, and especially in sooting flames. Detection methods may be divided into ICCD-based nanosecond-gate detection or a rotary-chopper electromechanical shutter-based CCD array detection, and the levels of background flame emission in individual cases would determine this critical design choice. Here, a process of Raman signal calibration based on ti,e crosstalk matrix

    Academic medical centers face barriers to training physicians in systems- and practice-based learning competencies needed to function in the changing health care environment. To address these problems, at the University of Virginia School of Medicine the authors developed the Clinical Health Economics System Simulation (CHESS), a computerized team-based quasi-competitive simulator to teach the principles and practical application of health economics. CHESS simulates treatment costs to patients and society as well as physician reimbursement. It is scenario based with residents grouped into three teams, each team playing CHESS using differing (fee-for-service or capitated) reimbursement models. Teams view scenarios and select from two or three treatment options that are medically justifiable yet have different potential cost implications. CHESS displays physician reimbursement and patient and societal costs for each scenario as well as costs and income summarized across all scenarios extrapolated to a physician's entire patient panel. The learners are asked to explain these findings and may change treatment options and other variables such as panel size and case mix to conduct sensitivity analyses in real time. Evaluations completed in 2003 by 68 (94%) CHESS resident and faculty participants at 19 U.S. residency programs preferred CHESS to a traditional lecture-and-discussion format to learn about medical decision making, physician reimbursement, patient costs, and societal costs. Ninety-eight percent reported increased knowledge of health economics after viewing the simulation. CHESS demonstrates the potential of computer simulation to teach health economics and other key elements of practice- and systems-based competencies.

  19. Advanced unambiguous state discrimination attack and countermeasure strategy in a practical B92 QKD system

    Even though unconditional security of B92 quantum key distribution (QKD) system is based on the assumption of perfect positive-operator-valued measures, practical B92 systems only utilize two projective measurements. Unfortunately, such implementation may degrade the security of the B92 QKD system due to Eve's potential attack exploiting the imperfection of system. In this paper, we propose an advanced attack strategy with an unambiguous state discrimination (USD) measurement which makes practical B92 QKD systems insecure even under a lossless channel. In addition, we propose an effective countermeasure against the advanced USD attack model by monitoring double-click events. We further address a fundamental approach to make the B92 QKD system tolerable to attack strategies with USD measurements using a multi-qubit scheme.

  20. Implementing Effective Mission Systems Engineering Practices During Early Project Formulation Phases

    2016-01-01

    Developing and implementing a plan for a NASA space mission can be a complicated process. The needs, goals, and objectives of any proposed mission or technology must be assessed early in the Project Life Cycle. The key to successful development of a space mission or flight project is the inclusion of systems engineering in early project formulation, namely during Pre-phase A, Phase A, and Phase B of the NASA Project Life Cycle. When a space mission or new technology is in pre-development, or "pre-Formulation", feasibility must be determined based on cost, schedule, and risk. Inclusion of system engineering during project formulation is key because in addition to assessing feasibility, design concepts are developed and alternatives to design concepts are evaluated. Lack of systems engineering involvement early in the project formulation can result in increased risks later in the implementation and operations phases of the project. One proven method for effective systems engineering practice during the pre-Formulation Phase is the use of a mission conceptual design or technology development laboratory, such as the Mission Design Lab (MDL) at NASA's Goddard Space Flight Center (GSFC). This paper will review the engineering process practiced routinely in the MDL for successful mission or project development during the pre-Formulation Phase.

    Objective Sentencing trends have created a demographic shift in prison populations. Greater numbers of inmates are aging and dying in prison, creating a demand for enhanced end-of-life care. Changing practice to meet escalating care demands in corrections settings is complicated by economic constraints, attitudinal barriers, and organizational features. This study explored perspectives of end-of-life care held by administrators in a state prison system to reveal challenges to changing practice to meet the needs of inmates suffering advanced illness and dying in prison. Design and Sample Qualitative interviews were conducted with 12 administrators from the central office of a state department of corrections. Results Key influences impacting end-of-life care services included: local prison culture; treatment versus security focus; case-by-case consideration; public sentiment; budget neutral approaches; and conflicting views of service targets. Conclusions These findings revealed the organizational structures, attitudes, and beliefs held by the administrative echelon of a state prison system and were used to guide the derivation of discrete approaches to changing practice in this complex system. Contextual evaluation permitted a much deeper understanding of the influences on changing practice in this hierarchical bureaucracy. This type of preliminary evaluation is crucial to infusing new practice initiatives in complex organizations caring for stigmatized, at-risk populations. PMID:24588128

    The overall research objective was to theoretically and empirically develop the ideas around a system of safety management practices (ten practices were elaborated), to test their relationship with objective safety statistics (such as accident rates), and to explore how these practices work to achieve positive safety results (accident prevention) through worker engagement. Data were collected using safety manager, supervisor and employee surveys designed to assess and link safety management system practices, employee perceptions resulting from existing practices, and safety performance outcomes. Results indicate the following: there is a significant negative relationship between the presence of ten individual safety management practices, as well as the composite of these practices, with accident rates; there is a significant negative relationship between the level of safety-focused worker emotional and cognitive engagement with accident rates; safety management systems and worker engagement levels can be used individually to predict accident rates; safety management systems can be used to predict worker engagement levels; and worker engagement levels act as mediators between the safety management system and safety performance outcomes (such as accident rates). Even though the presence of safety management system practices is linked with incident reduction and may represent a necessary first-step in accident prevention, safety performance may also depend on mediation by safety-focused cognitive and emotional engagement by workers. Thus, when organizations invest in a safety management system approach to reducing/preventing accidents and improving safety performance, they should also be concerned about winning over the minds and hearts of their workers through human performance-based safety management systems designed to promote and enhance worker engagement.

    Financial transparency is based on concepts for valid, standardized information that is readily accessible and routinely disseminated to stakeholders. While Congress and others continuously ask for an accounting of public health investments, transparency remains an ignored concept. The objective of this study was to examine financial transparency practices in other industries considered as part of the public health system. Key informants, regarded as financial experts on the operations of hospitals, school systems, and higher education, were a primary source of information. Principal findings were that system partners have espoused some concepts for financial transparency beginning in the early 20th century--signifying an 80-year implementation gap for public health. Critical features that promote accountability included standardized data collection methods and infrastructures, uniform practices for quantitative analysis of financial performance, and credentialing of the financial management workforce. Recommendations are offered on the basis of these findings to aid public health to close this gap by framing a movement toward transparency.

    The delivery of sterile products to the sterile field is essential to perioperative practice. The use of protective packaging for sterilized items is crucial to helping ensure that patients receive sterile items for surgical procedures. AORN's "Recommended practices for selection and use of packaging systems for sterilization" offers guidance to perioperative team members in evaluating, selecting, and using packaging systems that permit sterilization of the contents, prevent contamination of sterilized items until the package is opened for use, protect the items from damage during transport and storage, and permit aseptic delivery of the items to the sterile field.

    Health systems are in the midst of a transformation that is being driven by a variety of forces. This has important implications for medical educators because clinical practice environments play a key role in learning and professional development, and evolving health systems are beginning to demand that providers have "systems-ready" knowledge, attitudes, and skills. Such implications provide a clear mandate for medical schools to modify their goals and prepare physicians to practice flexibly within teams and effectively contribute to the improvement of health care delivery. In this context, the concepts of value-added medical education, authentic student roles, and health systems science are emerging as increasingly important. In this Article, the authors use a lens informed by communities of practice theory to explore these three concepts, examining the implications that the communities of practice theory has in the constructive reframing of educational practices-particularly common student roles and experiences-and charting future directions for medical education that better align with the needs of the health care system. The authors apply several key features of the communities of practice theory to current experiential roles for students, then propose a new approach to students' clinical experiences-value-added clinical systems learning roles-that provides students with opportunities to make meaningful contributions to patient care while learning health systems science at the patient and population level. Finally, the authors discuss implications for professional role formation and anticipated challenges to the design and implementation of value-added clinical systems learning roles.

  7. A Pathophysiological Model-Driven Communication for Dynamic Distributed Medical Best Practice Guidance Systems.

    There is a great divide between rural and urban areas, particularly in medical emergency care. Although medical best practice guidelines exist and are in hospital handbooks, they are often lengthy and difficult to apply clinically. The challenges are exaggerated for doctors in rural areas and emergency medical technicians (EMT) during patient transport. In this paper, we propose the concept of distributed executable medical best practice guidance systems to assist adherence to best practice from the time that a patient first presents at a rural hospital, through diagnosis and ambulance transfer to arrival and treatment at a regional tertiary hospital center. We codify complex medical knowledge in the form of simplified distributed executable disease automata, from the thin automata at rural hospitals to the rich automata in the regional center hospitals. However, a main challenge is how to efficiently and safely synchronize distributed best practice models as the communication among medical facilities, devices, and professionals generates a large number of messages. This complex problem of patient diagnosis and transport from rural to center facility is also fraught with many uncertainties and changes resulting in a high degree of dynamism. A critically ill patient's medical conditions can change abruptly in addition to changes in the wireless bandwidth during the ambulance transfer. Such dynamics have yet to be addressed in existing literature on telemedicine. To address this situation, we propose a pathophysiological model-driven message exchange communication architecture that ensures the real-time and dynamic requirements of synchronization among distributed emergency best practice models are met in a reliable and safe manner. Taking the signs, symptoms, and progress of stroke patients transported across a geographically distributed healthcare network as the motivating use case, we implement our communication system and apply it to our developed best practice

    Recent changes in policies allowing practitioners of Ayurveda, Yoga, Naturopathy, Unani, Siddha and Homoeopathy (AYUSH) to integrate into the mainstream of healthcare and also allowing practitioners of Ayurveda and Homoeopathy to perform medical termination of pregnancy (MTP) under the proposed amendment to the MTP bill have brought crosssystem practice into the limelight. We evaluate cross-system practice from its legal and ethical perspectives. Across judgments, the judiciary has held that cross-system practice is a form of medical negligence; however, it is permitted only in those states where the concerned governments have authorized it by a general or special order. Further, though a state government may authorize an alternative medicine doctor to prescribe allopathic medicines (or vice versa), it does not condone the prescription of wrong medicines or wrong diagnosis. Courts have also stated that prescribing allopathic medicines and misrepresenting these as traditional medicines is an unfair trade practice and not explaining the side-effects of a prescribed allopathic medicine amounts to medical negligence. Finally, the Supreme Court has cautioned that employing traditional medical practitioners who do not possess the required skill and competence to give allopathic treatment in hospitals and to let an emergency patient be treated by them is gross negligence. In the event of an unwanted outcome, the responsibility is completely on the hospital authorities. Therefore, there is an urgent need to abolish cross-system practice, invest in healthcare, and bring radical changes in health legislations to make right to healthcare a reality.

    Articles in the literature routinely describe advances in Content Based Image Retrieval (CBIR) and its potential for improving clinical practice, biomedical research and education. Several systems have been developed to address particular needs, however, surprisingly few are found to be in routine practical use. Our collaboration with the National Cancer Institute (NCI) has identified a need to develop tools to annotate and search a collection of over 100,000 cervigrams and related, anonymized patient data. One such tool developed for a projected need for retrieving similar patient images is the prototype CBIR system, called CervigramFinder, which retrieves images based on the visual similarity of particular regions on the cervix. In this article we report the outcomes from a usability study conducted at a primary meeting of practicing experts. We used the study to not only evaluate the system for software errors and ease of use, but also to explore its "user readiness", and to identify obstacles that hamper practical use of such systems, in general. Overall, the participants in the study found the technology interesting and bearing great potential; however, several challenges need to be addressed before the technology can be adopted.

    A practical millimeter-wave (mmw) holographic imaging system with tunable intermediate frequency (IF) attenuator has been developed. It can be used for the detection of concealed weapons at security checkpoints, especially the airport. The system is utilized to scan the passenger and detect the weapons hidden in the clothes. To reconstruct the three dimensions (3-D) image, a holographic mmw imaging algorithm based on aperture synthesis and back scattering is presented. The system is active and works at 28-33 GHz. Tunable IF attenuator is applied to compensate the intensity and phase differences between multi-channels and multi-frequencies.

    A macro expander technique has been adopted to generate a machine independent single user version of ANSI Standard MUMPS running on an 8080 Microcomputer. This approach makes it possible to have the medically oriented MUMPS language available on inexpensive systems suitable for small group practice settings. Substitution of another macro expansion set allows the same interpreter to be implemented on another computer, thereby providing compatibility with comparable or larger scale systems. Furthermore, since the global file handler can be separated from the interpreter, this approach permits development of a distributed MUMPS system with no change in applications software.

  13. Practical solutions to implementing "Born Semantic" data systems

    Leadbetter, A.; Buck, J. J. H.; Stacey, P.

    2015-12-01

    The concept of data being "Born Semantic" has been proposed in recent years as a Semantic Web analogue to the idea of data being "born digital"[1], [2]. Within the "Born Semantic" concept, data are captured digitally and at a point close to the time of creation are annotated with markup terms from semantic web resources (controlled vocabularies, thesauri or ontologies). This allows heterogeneous data to be more easily ingested and amalgamated in near real-time due to the standards compliant annotation of the data. In taking the "Born Semantic" proposal from concept to operation, a number of difficulties have been encountered. For example, although there are recognised methods such as Header, Dictionary, Triples [3] for the compression, publication and dissemination of large volumes of triples these systems are not practical to deploy in the field on low-powered (both electrically and computationally) devices. Similarly, it is not practical for instruments to output fully formed semantically annotated data files if they are designed to be plugged into a modular system and the data to be centrally logged in the field as is the case on Argo floats and oceanographic gliders where internal bandwidth becomes an issue [2]. In light of these issues, this presentation will concentrate on pragmatic solutions being developed to the problem of generating Linked Data in near real-time systems. Specific examples from the European Commission SenseOCEAN project where Linked Data systems are being developed for autonomous underwater platforms, and from work being undertaken in the streaming of data from the Irish Galway Bay Cable Observatory initiative will be highlighted. Further, developments of a set of tools for the LogStash-ElasticSearch software ecosystem to allow the storing and retrieval of Linked Data will be introduced. References[1] A. Leadbetter & J.

    The clinical and administrative processes in today's healthcare environment are becoming increasingly complex. Multiple providers, new technology, competition, and the growing ubiquity of information all contribute to the notion of health care as a complex system. A complex system (CS) is characterized by a highly connected network of entities (e.g., physical objects, people or groups of people) from which higher order behavior emerges. Research in the transdisciplinary field of CS has focused on the use of computational modeling and simulation as a methodology for analyzing CS behavior. The creation of virtual worlds through computer simulation allows researchers to analyze multiple variables simultaneously and begin to understand behaviors that are common regardless of the discipline. The application of CS principles, mediated through computer simulation, informs nursing practice of the benefits and drawbacks of new procedures, protocols and practices before having to actually implement them. The inclusion of new computational tools and their applications in nursing education is also gaining attention. For example, education in CSs and applied computational applications has been endorsed by The Institute of Medicine, the American Organization of Nurse Executives and the American Association of Colleges of Nursing as essential training of nurse leaders. The purpose of this article is to review current research literature regarding CS science within the context of expert practice and implications for the education of nurse leadership roles. The article focuses on 3 broad areas: CS defined, literature review and exemplars from CS research and applications of CS theory in nursing leadership education. The article also highlights the key role nursing informaticists play in integrating emerging computational tools in the analysis of complex nursing systems.

    2009-08-01

    This paper focuses on system engineering development issues driving satellite remote sensing instrumentation cost and schedule. A key best practice is early assessment of mission and instrumentation requirements priorities driving performance trades among major instrumentation measurements: Radiometry, spatial field of view and image quality, and spectral performance. Key lessons include attention to technology availability and applicability to prioritized requirements, care in applying heritage, approaching fixed-price and cost-plus contracts with appropriate attention to risk, and assessing design options with attention to customer preference as well as design performance, and development cost and schedule. A key element of success either in contract competition or execution is team experience. Perhaps the most crucial aspect of success, however, is thorough requirements analysis and flowdown to specifications driving design performance with sufficient parameter margin to allow for mistakes or oversights - the province of system engineering from design inception to development, test and delivery.

    The privileging of pharmacists for clinical activities and the impact that privileging has on enhancing the scope of pharmacy practice in health systems are reviewed. Health-system pharmacists or pharmacy leaders must gain a thorough understanding of the credentialing and privileging process as they broaden their scope of practice. Clinical privileging affords an expanded scope of practice that is recognized at the institutional level and formally elevates the pharmacist to that of a nonphysician provider. The installation of privileging processes is expected to take many months to complete for individual institutions and should begin now in anticipation of provider status. Model institutions, including Truman Medical Centers, Johns Hopkins Hospital, and The Ohio State University Wexner Medical Center, are highlighted in this article and provide their individual approach to clinical privileging that can be applied to other institutions. The development and evaluation of these programs have given valuable insight into how this individual approach translates to health systems across the country and how the pharmacy profession can continue to unite to convey the value of pharmacists in improving patient care. In preparation for the potential approval of pharmacist provider status across the United States, it is essential that pharmacists are privileged by the medical staff at their respective institution. Clinical privileges must be strategically developed with a focus on cost and quality aims and meeting the needs of patients. Implementation and maintenance of high-performing pharmacy privileging programs require both successful leadership and management skills and an understanding of the interprofessional nature of healthcare.

    Many hospital information systems have been developed and implemented to collect clinical data from the bedside and have used the information to improve patient care. Because of a growing awareness that the use of clinical information improves quality of care and patient outcomes, measuring tools (electronic and paper based) have been developed, but most of them require multiple steps of data collection and analysis. This necessitated the development of a Web-based Nursing Practice and Research Information Management System that processes clinical nursing data to measure nurses' delivery of care and its impact on patient outcomes and provides useful information to clinicians, administrators, researchers, and policy makers at the point of care. This pilot study developed a computer algorithm based on a falls prevention protocol and programmed the prototype Web-based Nursing Practice and Research Information Management System. It successfully measured performance of nursing care delivered and its impact on patient outcomes successfully using clinical nursing data from the study site. Although Nursing Practice and Research Information Management System was tested with small data sets, results of study revealed that it has the potential to measure nurses' delivery of care and its impact on patient outcomes, while pinpointing components of nursing process in need of improvement.

    Eric Cornelius; Mark Fabro

    these issues and to accommodate for the diversity in both system and architecture types, a framework based in recommended practices to address forensics in the control systems domain is required. This framework must be fully flexible to allow for deployment into any control systems environment regardless of technologies used. Moreover, the framework and practices must provide for direction on the integration of modern network security technologies with traditionally closed systems, the result being a true defense-in-depth strategy for control systems architectures. This document takes the traditional concepts of cyber forensics and forensics engineering and provides direction regarding augmentation for control systems operational environments. The goal is to provide guidance to the reader with specifics relating to the complexity of cyber forensics for control systems, guidance to allow organizations to create a self-sustaining cyber forensics program, and guidance to support the maintenance and evolution of such programs. As the current control systems cyber security community of interest is without any specific direction on how to proceed with forensics in control systems environments, this information product is intended to be a first step.« less

    The purpose of this paper is to describe the components of a next-generation electronic nursing records system ensuring full semantic interoperability and integrating evidence into the nursing records system. A next-generation electronic nursing records system based on detailed clinical models and clinical practice guidelines was developed at Seoul National University Bundang Hospital in 2013. This system has two components, a terminology server and a nursing documentation system. The terminology server manages nursing narratives generated from entity-attribute-value triplets of detailed clinical models using a natural language generation system. The nursing documentation system provides nurses with a set of nursing narratives arranged around the recommendations extracted from clinical practice guidelines. An electronic nursing records system based on detailed clinical models and clinical practice guidelines was successfully implemented in a hospital in Korea. The next-generation electronic nursing records system can support nursing practice and nursing documentation, which in turn will improve data quality.

    2013-10-01

    This study aimed to organize the system features of decision support technologies targeted at nursing practice into assessment, problem identification, care plans, implementation, and outcome evaluation. It also aimed to identify the range of the five stage-related sequential decision supports that computerized clinical decision support systems provided. MEDLINE, CINAHL, and EMBASE were searched. A total of 27 studies were reviewed. The system features collected represented the characteristics of each category from patient assessment to outcome evaluation. Several features were common across the reviewed systems. For the sequential decision support, all of the reviewed systems provided decision support in sequence for patient assessment and care plans. Fewer than half of the systems included problem identification. There were only three systems operating in an implementation stage and four systems in outcome evaluation. Consequently, the key steps for sequential decision support functions were initial patient assessment, problem identification, care plan, and outcome evaluation. Providing decision support in such a full scope will effectively help nurses' clinical decision making. By organizing the system features, a comprehensive picture of nursing practice-oriented computerized decision support systems was obtained; however, the development of a guideline for better systems should go beyond the scope of a literature review.

    Adoption of evidence-based practices takes place at a glacial place in healthcare. This research will pilot test an innovative implementation strategy - systems consultation -intended to speed the adoption of evidence-based practice in primary care. The strategy is based on tenets of systems engineering and has been extensively tested in addiction treatment. Three innovations have been included in the strategy - translation of a clinical practice guideline into a checklist-based implementation guide, the use of physician peer coaches ('systems consultants') to help clinics implement the guide, and a focus on reducing variation in practices across prescribers and clinics. The implementation strategy will be applied to improving opioid prescribing practices in primary care, which may help ultimately mitigate the increasing prevalence of opioid abuse and addiction. The pilot test will compare four intervention clinics to four control clinics in a matched-pairs design. A leading clinical guideline for opioid prescribing has been translated into a checklist-based implementation guide in a systematic process that involved experts who wrote the guideline in consultation with implementation experts and primary care physicians. Two physicians with expertise in family and addiction medicine are serving as the systems consultants. Each systems consultant will guide two intervention clinics, using two site visits and follow-up communication by phone and email, to implement the translated guideline. Mixed methods will be used to test the feasibility, acceptability, and preliminary effectiveness of the implementation strategy in an evaluation that meets standards for 'fully developed use' of the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, Maintenance). The clinic will be the primary unit of analysis. The systems consultation implementation strategy is intended to generalize to the adoption of other clinical guidelines. This pilot test is intended to prepare

    In this study, we examined speech recognition functionality in four leading dental practice management systems. Twenty dental students used voice to chart a simulated patient with 18 findings in each system. Results show it can take over a minute to chart one finding and that users frequently have to repeat commands. Limited functionality, poor usability and a high error rate appear to retard adoption of speech recognition in dentistry.

    Systems-based practice focuses on the organization, financing, and delivery of medical services. The American Association of Medical Colleges has recommended that systems-based practice be incorporated into medical schools' curricula. However, experiential learning in systems-based practice, including practical strategies to improve the quality and efficiency of clinical care, is often absent from or inconsistently included in medical education. A multidisciplinary clinician and nonclinician faculty team partnered with a cardiology outpatient clinic to design a 9-month clerkship for 1st-year medical students focused on systems-based practice, delivery of clinical care, and strategies to improve the quality and efficiency of clinical operations. The clerkship was called the Action Research Program. In 2013-2014, 8 trainees participated in educational seminars, research activities, and 9-week clinic rotations. A qualitative process and outcome evaluation drew on interviews with students, clinic staff, and supervising physicians, as well as students' detailed field notes. The Action Research Program was developed and implemented at the University of California, San Francisco, an academic medical center in the United States. All educational activities took place at the university's medical school and at the medical center's cardiology outpatient clinic. Students reported and demonstrated increased understanding of how care delivery systems work, improved clinical skills, growing confidence in interactions with patients, and appreciation for patients' experiences. Clinicians reported increased efficiency at the clinic level and improved performance and job satisfaction among medical assistants as a result of their unprecedented mentoring role with students. Some clinicians felt burdened when students shadowed them and asked questions during interactions with patients. Most student-led improvement projects were not fully implemented. The Action Research Program is a

    Over the years, traditional anaesthesia record keeping system has been the backbone of anaesthesiology ever since its introduction in the 1890s by Dr. Harvey Cushing and Dr. Ernest A. Codman. Besides providing the important information regarding patients’ vital physiologic parameters, paper records had been a reliable source for various clinical research activities. The introduction of electronic monitoring gadgets and electronic record keeping systems has revolutionised the anaesthesiology practice to a large extent. Recently, the introduction of anaesthesia information management system (AIMS), which incorporates all the features of monitoring gadgets, such as electronic storage of large accurate data, quality assurance in anaesthesia, enhancing patient safety, ensuring legal protection, improved billing services and effecting an organisational change, is almost a revolution in modern-day anaesthesiology practice. The clinical research activities that are responsible for taking anaesthesiology discipline to higher peaks have also been boosted by the amalgamation of AIMS, enabling multicenter studies and sharing of clinical data. Barring few concerns in its installation, cost factors and functional aspects, the future of AIMS seems to be bright and will definitely prove to be a boon for modern-day anaesthesiology practice.

  13. Physician Practice Audit Targets Now Become Hospital and Health System Compliance Risks.

    PubMed

    Hirsch, Ronald L

    2015-01-01

    In 2013, 22% of the federal budget was spent on Medicare and Medicaid. The Medicare Trust Fund is forecast to be depleted in 2030. More than 12% of Medicare fee-for-service payments in 2014 were made in error. These factors have led Congress to apply more pressure to reduce improper payments. Although hospitals were the initial targets because of their higher reimbursement, recent efforts have shifted to physician billing. Hospitals and health systems continue to acquire physician practices, making them liable for the billing activities of physicians. And for physicians who remain independent, the cost and effort required to respond to audits and denials can be financially devastating, further demonstrating the importance of prevention. This article addresses some of the common audit targets and mistakes made by physicians and provides strategies for physician practices and health systems to respond to and, ultimately, avoid these denials.

  14. Practical Performance Analysis for Multiple Information Fusion Based Scalable Localization System Using Wireless Sensor Networks.

    PubMed

    In practical localization system design, researchers need to consider several aspects to make the positioning efficiently and effectively, e.g., the available auxiliary information, sensing devices, equipment deployment and the environment. Then, these practical concerns turn out to be the technical problems, e.g., the sequential position state propagation, the target-anchor geometry effect, the Non-line-of-sight (NLOS) identification and the related prior information. It is necessary to construct an efficient framework that can exploit multiple available information and guide the system design. In this paper, we propose a scalable method to analyze system performance based on the Cramér-Rao lower bound (CRLB), which can fuse all of the information adaptively. Firstly, we use an abstract function to represent all of the wireless localization system model. Then, the unknown vector of the CRLB consists of two parts: the first part is the estimated vector, and the second part is the auxiliary vector, which helps improve the estimation accuracy. Accordingly, the Fisher information matrix is divided into two parts: the state matrix and the auxiliary matrix. Unlike the theoretical analysis, our CRLB can be a practical fundamental limit to denote the system that fuses multiple information in the complicated environment, e.g., recursive Bayesian estimation based on the hidden Markov model, the map matching method and the NLOS identification and mitigation methods. Thus, the theoretical results are approaching the real case more. In addition, our method is more adaptable than other CRLBs when considering more unknown important factors. We use the proposed method to analyze the wireless sensor network-based indoor localization system. The influence of the hybrid LOS/NLOS channels, the building layout information and the relative height differences between the target and anchors are analyzed. It is demonstrated that our method exploits all of the available information for

    2007-12-01

    The purpose of this study was to generate a grounded theory that will reflect the experiences of advanced practice nurses (APNs) working as critical care nurse practitioners (NPs) and clinical nurse specialists (CNS) with computer-based decision-making systems. A study design using grounded theory qualitative research methods and convenience sampling was employed in this study. Twenty-three APNs (13 CNS and 10 NPs) were recruited from 16 critical care units located in six large urban medical centers in the U.S. Midwest. Single-structured in-depth interviews with open-ended audio-taped questions were conducted with each APN. Through this process, APNs defined what they consider to be relevant themes and patterns of clinical decision system use in their critical care practices, and they identified the interrelatedness of the conceptual categories that emerged from the results. Data were analyzed using the constant comparative analysis method of qualitative research. APN participants were predominantly female, white/non-Hispanic, had a history of access to the clinical decision system used in their critical care settings for an average of 14 months, and had attended a formal training program to learn how to use clinical decision systems. "Forecasting decision outcomes," which was defined as the voluntary process employed to forecast the outcomes of patient care decisions in critical care prior to actual decision making, was the core variable describing system use that emerged from the responses. This variable consisted of four user constructs or components: (a) users' perceptions of their initial system learning experience, (b) users' sense of how well they understand how system technology works, (c) users' understanding of how system inferences are created or derived, and (d) users' relative trust of system-derived data. Each of these categories was further described through the grounded theory research process, and the relationships between the categories were

    We report on an experimental implementation of an attack of a practical quantum key distribution system [1], based on a vulnerability of single photon detectors [2]. An intercept/resend-like attack has been carried out which revealed 100% of the raw key generated between the legitimate communication partners. No increase of the error ratio was observed, which is usually considered a reliable witness for any eavesdropping attempt. We also present an experiment which shows that this attack is not revealed by key distribution protocols probing for eavesdroppers by testing a Bell inequality [3], and discuss implications for practical quantum key distribution.[4pt] [1] I.

    This paper addresses the issue of clinical knowledge in nursing, and the feasibility of emulating this knowledge into expert system technology. The perspective on patterns of knowing for nursing practice, advanced by Carper (1978), serves as point of departure. The four patterns of knowing -- empirics, esthetics, ethics, personal knowledge -- are evaluated as to the extent to which they can be emulated in clinical expert systems, given constraints imposed by the current technology of these systems.

    With the emergence of an information society, the idea of protecting sensitive data is steadily gaining importance. Conventional encryption methods may not be sufficient to guarantee data protection in the future. Quantum key distribution (QKD) is an emerging technology that exploits fundamental physical properties to guarantee perfect security in theory. However, it is not easy to ensure in practice that the implementations of QKD systems are exactly in line with the theoretical specifications. Such theory-practice deviations can open loopholes and compromise security. Several such loopholes have been discovered and investigated in the last decade. These activities have motivated the proposal and implementation of appropriate countermeasures, thereby preventing future attacks and enhancing the practical security of QKD. This article introduces the so-called field of quantum hacking by summarising a variety of attacks and their prevention mechanisms.

    Quantum-cryptography key distribution (QCKD) experiments have been recently reported using polarization-entangled photons. However, in any practical realization, quantum systems suffer from either unwanted or induced interactions with the environment and the quantum measurement system, showing up as quantum and, ultimately, statistical noise. In this paper, we investigate how an ideal polarization entanglement in spontaneous parametric down-conversion (SPDC) suffers quantum noise in its practical implementation as a secure quantum system, yielding errors in the transmitted bit sequence. Since all SPDC-based QCKD schemes rely on the measurement of coincidence to assert the bit transmission between the two parties, we bundle up themore » overall quantum and statistical noise in an exhaustive model to calculate the accidental coincidences. This model predicts the quantum-bit error rate and the sifted key and allows comparisons between different security criteria of the hitherto proposed QCKD protocols, resulting in an objective assessment of performances and advantages of different systems.« less

    Ensuring the safe, effective management of patients requires efficient processes of care within a smoothly operating system in which highly reliable teams of talented, skilled health care providers are able to use the vast array of high-technology resources and intensive care techniques available. Simulation can play a unique role in exploring and improving the complex perioperative system by proactively identifying latent safety threats and mitigating their damage to ensure that all those who work in this critical health care environment can provide optimal levels of patient care. A panel of five experts from a wide range of institutions was brought together to discuss the added value of simulation-based training for improving systems-based aspects of the perioperative service line. Panelists shared the way in which simulation was demonstrated at their institutions. The themes discussed by each panel member were delineated into four avenues through which simulation-based techniques have been used. Simulation-based techniques are being used in (1) testing new clinical workspaces and facilities before they open to identify potential latent conditions; (2) practicing how to identify the deteriorating patient and escalate care in an effective manner; (3) performing prospective root cause analyses to address system weaknesses leading to sentinel events; and (4) evaluating the efficiency and effectiveness of the electronic health record in the perioperative setting. This focused review of simulation-based interventions to test and improve components of the perioperative microsystem, which includes literature that has emerged since the panel's presentation, highlights the broad-based utility of simulation-based technologies in health care.

    The majority of primary care consultations in Malaysia occur in the general practice clinics. To date, there is no comprehensive documentation of the morbidity and practice activities in this setting. We reported the reasons for encounter, diagnoses and process of care in urban general practice and the influence of payment system on the morbidity and practice activities. 115 clinics in Kuala Lumpur, Ipoh and Penang participated in this study. General practitioners in these clinics completed a 2-page questionnaire for each of the 30 consecutive patients. The questionnaire requested for the following information: demographic data, reasons for encounter, important physical findings, diagnoses, investigations ordered, outpatient procedures performed, medical certificate given, medication prescribed and referral made. The morbidity (reasons for encounter and diagnoses) was coded using ICPC-2 and the medication data was coded using MIMS Classification Index. During 3481 encounters, 5300 RFEs (152 RFEs per 100 encounters) and 3342 diagnoses (96 diagnoses per 100 encounters) were recorded. The majority of the RFEs and diagnoses are in the following ICPC Chapters: Respiratory, General and unspecified, Digestive, Neurological, Musculoskeletal and Skin. The frequencies of selected aspects of the process of care (rate per 100 encounters) were: laboratory investigations 14.7, outpatient procedures 2.4, sick certification 26.9, referral 2.4, and medication prescription 244. Consultation for chronic diseases and acute infections were influenced more by demographic variables (age, employment) rather than payment system. Cash-paying patients were more likely to receive laboratory investigations and injections. This study demonstrated the breadth of clinical care in the general practice. Relatively fewer patients consulted specifically for preventive care and treatment of chronic diseases. The frequencies of outpatient procedures and referrals appeared to be low. Payment system

    Teaching graduate family nursing students the important and delicate practice of entering into and mitigating families' illness suffering signifies an educational practice that is rigorous, intense, and contextual, yet not articulated as expounded knowledge. This study examined the pedagogical practices of the advanced practice of Family Systems Nursing (FSN) as taught to master's and doctoral nursing students at the Family Nursing Unit, University of Calgary, using observation of expert and novice clinical practice, live supervision, videotape review, presession hypothesizing, clinical documentation, and the writing of therapeutic letters to families. A triangulation of research methods and data collection strategies, interpretive ethnography, autoethnography, and hermeneutics, were used. Students reported an intensity of learning that had both useful and limiting consequences as they developed skills in therapeutic conversations with families experiencing illness. Faculty used an intentional pedagogical process to encourage growth in perceptual, conceptual, and executive knowledge and skills of working with families.

    2016-12-01

    Practice audits are useful opportunities to improve practice efficiency and effectiveness, reduce clinical errors, demonstrate quality care to stakeholders, promote high standards of practice, lower the risk of liability, and foster practice change. However, a benefit that is usually overlooked is the possibility of publication of the results of a practice audit. Publication (research) has a number of benefits for the clinician, including skill development as a scholar, communicator, professional, and collaborator. A practice audit is beneficial to an individual physician; furthermore, publication of the audit results could be beneficial for many others such as health care providers, patients, and other stakeholders in a health care system. The problem is that practice audits often begin without a clear plan. The important steps in planning and carrying out a practice audit can be captured by thinking about how a research publication evolves. Thus, a good researcher is a good practice auditor. This paper reviews the author's experience and provides examples and directions of the process of practice-audit-publish.

    Practical considerations that will strongly affect the imaging capabilities of reflecting systems for extreme-ultraviolet (XUV) projection lithography include manufacturing tolerances and thermal distortion of the mirror surfaces due to absorption of a fraction of the incident radiation beam. We have analyzed the potential magnitudes of these effects for two types of reflective projection optical designs. We find that concentric, symmetric two-mirror systems are less sensitive to manufacturing errors and thermal distortion than off-axis, four-mirror systems.

    2016-03-11

    We present practical methods to measure entanglement for quantum simulators that can be realized with trapped ions, cold atoms, and superconducting qubits. Focusing on long- and short-range Ising-type Hamiltonians, we introduce schemes that are applicable under realistic experimental conditions including mixedness due to, e.g., noise or temperature. In particular, we identify a single observable whose expectation value serves as a lower bound to entanglement and that may be obtained by a simple quantum circuit. As such circuits are not (yet) available for every platform, we investigate the performance of routinely measured observables as quantitative entanglement witnesses. Possible applications include experimental studies of entanglement scaling in critical systems and the reliable benchmarking of quantum simulators.

    Following recent concerns about patients' inability to book appointments in advance, this study examined the relationship between the proportion of GP appointments reserved for same-day booking, and patient satisfaction with appointment systems. In a survey of 12,825 patients in 47 practices, it was found that a 10% increase in the proportion of same-day appointments was associated with an 8% reduction in the proportion of patients satisfied. Practices should be wary of increasing the level of same-day appointments to meet access targets.

    We present some analysis and conclusions from a case study of the culture and practices of scientists at the Met Office and Hadley Centre working on the development of software for climate and Earth System models using the MetUM infrastructure. The study examined how scientists think about software correctness, prioritize their requirements in making changes, and develop a shared understanding of the resulting models. We conclude that highly customized techniques driven strongly by scientific research goals have evolved for verification and validation of such models. In a formal software engineering context these represents costly, but invaluable, software integration tests with considerable benefits. The software engineering practices seen also exhibit recognisable features of both agile and open source software development projects - self-organisation of teams consistent with a meritocracy rather than top-down organisation, extensive use of informal communication channels, and software developers who are generally also users and science domain experts. We draw some general conclusions on whether these practices work well, and what new software engineering challenges may lie ahead as Earth System models become ever more complex and petascale computing becomes the norm.

    The urological practice setting in Germany has changed tremendously over the last years. Group practices with two or more urologists working together are becoming more and more popular. At the same time, marketing has become essential even for urologists. To evaluate the patient flow to our group practice, we asked all new patients to fill out a questionnaire (n=2112). We also evaluated the efficacy of our recall system. The analysis showed that patients were 18-93 years old (mean 57 years), 68% being male and 32% female. The largest age group consisted of 41-50-year-olds. The most important reasons for choosing our practice were recommendations by general practitioners in 38%, recommendations by specialists in 11%, and recommendations by friends and relatives in 27%. Five percent of the patients chose the practice because of the Internet home page and 10% because of entries in various phone books. Three percent of the patients came because of newspaper articles about the practice owners, and <1% had attended patient presentations. The Internet was used mainly by 31-40-year-old patients. Our recall system showed an efficacy of 59%. In summary, a good reputation in the medical society as well as in the neighbourhood is still the best advertising for a urological practice. Phone books are increasingly becoming less important, and the Internet is increasingly attractive to the younger population. Recall systems can also be useful for urological practices.

    The introduction of health information technology systems, electronic health records in particular, is changing the nature of how clinicians interact with patients. Lack of knowledge remains on how best to integrate such systems in the exam room. The purpose of this systematic review was to (1) distill "best" behavioral and communication practices recommended in the literature for clinicians when interacting with patients in the presence of computerized systems during a clinical encounter, (2) weigh the evidence of each recommendation, and (3) rank evidence-based recommendations for electronic health record communication training initiatives for clinicians. We conducted a literature search of 6 databases, resulting in 52 articles included in the analysis. We extracted information such as study setting, research design, sample, findings, and implications. Recommendations were distilled based on consistent support for behavioral and communication practices across studies. Eight behavioral and communication practices received strong support of evidence in the literature and included specific aspects of using computerized systems to facilitate conversation and transparency in the exam room, such as spatial (re)organization of the exam room, maintaining nonverbal communication, and specific techniques that integrate the computerized system into the visit and engage the patient. Four practices, although patient-centered, have received insufficient evidence to date. We developed an evidence base of best practices for clinicians to maintain patient-centered communications in the presence of computerized systems in the exam room. Further work includes development and empirical evaluation of evidence-based guidelines to better integrate computerized systems into clinical care. © The Author 2016.

    Transfusion laboratories with transfusion committees have a responsibility to monitor transfusion practice and generate improvements in clinical decision-making and red cell usage. However, this can be problematic and expensive because data cannot be readily extracted from most laboratory information systems. To overcome this problem, we developed and introduced a system to electronically extract and collate extensive amounts of data from two laboratory information systems and to link it with ICD10 clinical codes in a new database using standard information technology. Three data files were generated from two laboratory information systems, ULTRA (version 3.2) and TM, using standard information technology scripts. These were patient pre- and post-transfusion haemoglobin, blood group and antibody screen, and cross match and transfusion data. These data together with ICD10 codes for surgical cases were imported into an MS ACCESS database and linked by means of a unique laboratory number. Queries were then run to extract the relevant information and processed in Microsoft Excel for graphical presentation. We assessed the utility of this data extraction system to audit transfusion practice in a 600-bed adult tertiary hospital over an 18-month period. A total of 52 MB of data were extracted from the two laboratory information systems for the 18-month period and together with 2.0 MB theatre ICD10 data enabled case-specific transfusion information to be generated. The audit evaluated 15,992 blood group and antibody screens, 25,344 cross-matched red cell units and 15,455 transfused red cell units. Data evaluated included cross-matched to transfusion ratios and pre- and post-transfusion haemoglobin levels for a range of clinical diagnoses. Data showed significant differences between clinical units and by ICD10 code. This method to electronically extract large amounts of data and linkage with clinical databases has provided a powerful and sustainable tool for monitoring

    Hospital administration is very important and many hospitals carry out activity-based costing under comprehensive medicine. However, nursing cost is unclear, because nursing practice is expanding both quantitatively and qualitatively and it is difficult to grasp all nursing practices, and nursing cost is calculated in many cases comprehensively. On the other hand, a nursing information system (NIS) is implemented in many hospitals in Japan and we are beginning to get nursing practical data. In this paper, we propose a nursing cost accounting model and we simulate a cost by nursing contribution using NIS data.

    2015-12-01

    Femtocell is a novel technology that is used for escalating indoor coverage as well as the capacity of traditional cellular networks. However, interference is the limiting factor for performance improvement due to co-channel deployment between macrocells and femtocells. The traditional network planning is not feasible because of the random deployment of femtocells. Therefore, self-organization approaches are the key to having successful deployment of femtocells. This study presents the joint resource block (RB) and power allocation task for the two-tier femtocell network in a self-organizing manner, with the concern to minimizing the impact of interference and maximizing the energy efficiency. In this study, we analyze the performance of the system in terms of the energy efficiency, which is composed of both the transmission and circuit power. Most of the previous studies investigate the performance regarding the throughput requirement of the two-tier femtocell network while the energy efficiency aspect is largely ignored. Here, the joint allocation task is modeled as a non-cooperative game which is demonstrated to exhibit pure and unique Nash equilibrium. In order to reduce the complexity of the proposed non-cooperative game, the joint RB and power allocation task is divided into two subproblems: an RB allocation and a particle swarm optimization-based power allocation. The analysis of the proposed game is carried out in terms of not only energy efficiency but also throughput. With practical 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE) parameters, the simulation results illustrate the superior performance of the proposed game as compared to the traditional methods. Also, the comparison is carried out with the joint allocation scheme which only considers the throughput as the objective function. The results illustrate that significant performance improvement is achieved in terms of energy efficiency with slight loss in the throughput. The

    In 1999, the Accreditation Council for Graduate Medical Education identified 6 general competencies in which all residents must receive training. In the decade since these requirements went into effect, practice-based learning and improvement (PBLI) and systems-based practice (SBP) have proven to be the most challenging competencies to teach and assess. Because PBLI and SBP both are related to quality improvement (QI) principles and processes, we developed a QI-based curriculum to teach these competencies to our fellows. This experiential curriculum engaged our fellows in our neonatal intensive care unit's (NICU's) structured QI process. After identifying specific patient outcomes in need of improvement, our fellows applied validated QI methods to develop evidence-based treatment protocols for our neonatal intensive care unit. These projects led to immediate and meaningful improvements in patient care and also afforded our fellows various means by which to demonstrate their competence in PBLI and SBP. Our use of portfolios enabled us to document our fellows' performance in these competencies quite easily and comprehensively. Given the clinical and educational structures common to most intensive care unit-based training programs, we believe that a QI-based curriculum such as ours could be adapted by others to teach and assess PBLI and SBP.

    There are national and international clinical practice guidelines for systemic lupus erythematosus treatment. Nonetheless, most of them are not designed for the Mexican population or are devoted only to the treatment of certain disease manifestations, like lupus nephritis, or are designed for some physiological state like pregnancy. The Mexican College of Rheumatology aimed to create clinical practice guidelines that included the majority of the manifestations of systemic lupus erythematosus, and also incorporated guidelines in controversial situations like vaccination and the perioperative period. The present document introduces the «Clinical Practice Guidelines for the Treatment of Systemic Lupus Erythematosus» proposed by the Mexican College of Rheumatology, which could be useful mostly for non-rheumatologist physicians who need to treat patients with systemic lupus erythematosus without having the appropriate training in the field of rheumatology. In these guidelines, the reader will find recommendations on the management of general, articular, kidney, cardiovascular, pulmonary, neurological, hematologic and gastrointestinal manifestations, and recommendations on vaccination and treatment management during the perioperative period.

  1. A model of formative assessment practice in secondary science classrooms using an audience response system

    NASA Astrophysics Data System (ADS)

    Shirley, Melissa L.

    Formative assessment involves the probing of students' ideas to determine their level of understanding during the instructional sequence. Often conceptualized as a cycle, formative assessment consists of the teacher posing an instructional task to students, collecting data about student understanding, and engaging in follow-up strategies such as clarifying student understanding and adjusting instruction to meet learning needs. Despite having been shown to increase student achievement in a variety of classroom settings, formative assessment remains a relative weak area of teacher practice. Methods that enhance formative assessment strategies may therefore have a positive effect on student achievement. Audience response systems comprise a broad category of technologies that support richer classroom interaction and have the potential to facilitate formative assessment. Results from a large national research study, Classroom Connectivity in Promoting Mathematics and Science Achievement (CCMS), show that students in algebra classrooms where the teacher has implemented a type of audience response system experience significantly higher achievement gains compared to a control group. This suggests a role for audience response systems in promoting rich formative assessment. The importance of incorporating formative assessment strategies into regular classroom practice is widely recognized. However, it remains challenging to identify whether rich formative assessment is occurring during a particular class session. This dissertation uses teacher interviews and classroom observations to develop a fine-grained model of formative assessment in secondary science classrooms employing a type of audience response system. This model can be used by researchers and practitioners to characterize components of formative assessment practice in classrooms. A major component of formative assessment practice is the collection and aggregation of evidence of student learning. This dissertation

    In this paper, we present a free viewpoint video generation system with billboard representation for soccer games. Free viewpoint video generation is a technology that enables users to watch 3-D objects from their desired viewpoints. Practical implementation of free viewpoint video for sports events is highly demanded. However, a commercially acceptable system has not yet been developed. The main obstacles are insufficient user-end quality of the synthesized images and highly complex procedures that sometimes require manual operations. In this work, we aim to develop a commercially acceptable free viewpoint video system with a billboard representation. A supposed scenario is that soccer games during the day can be broadcasted in 3-D, even in the evening of the same day. Our work is still ongoing. However, we have already developed several techniques to support our goal. First, we captured an actual soccer game at an official stadium where we used 20 full-HD professional cameras. Second, we have implemented several tools for free viewpoint video generation as follow. In order to facilitate free viewpoint video generation, all cameras should be calibrated. We calibrated all cameras using checker board images and feature points on the field (cross points of the soccer field lines). We extract each player region from captured images manually. The background region is estimated by observing chrominance changes of each pixel in temporal domain (automatically). Additionally, we have developed a user interface for visualizing free viewpoint video generation using a graphic library (OpenGL), which is suitable for not only commercialized TV sets but also devices such as smartphones. However, practical system has not yet been completed and our study is still ongoing.

    Traditional beliefs, knowledge and practices are formally integrated into the Ecuadorian health system. We sought to understand whether they are integrated in practice. Qualitative data were collected in two rural parishes in the central highlands of Ecuador through four focus group discussions (30 participants), eight key informant interviews, three participatory exercises (24 participants), structured observations of health facilities and analysis of official documents. We found different levels of integration, coexistence, tolerance, and intolerance of traditional health beliefs and practices in health facilities. One parish has undergone dramatic social and cultural transformation, and the role of traditional birth attendants is limited. In the other parish, traditional indigenous norms and values persist, and traditional birth attendants are sought during pregnancy and childbirth. The degree to which traditional birth attendants, indigenous women and their families are included or excluded from public health services depends largely on decisions taken by local health professionals. Formal policies in Ecuador stipulate that health care should be intercultural, but the role of traditional birth attendants is not necessarily incorporated in practice. The integration of culturally-informed beliefs and practices is critical for providing appropriate health services to members of vulnerable populations. © The Author 2016.

  6. Applying a family systems lens to proxy decision making in clinical practice and research.

    When patients are incapacitated and face serious illness, family members must make medical decisions for the patient. Medical decision sciences give only modest attention to the relationships among patients and their family members, including impact that these relationships have on the decision-making process. A review of the literature reveals little effort to systematically apply a theoretical framework to the role of family interactions in proxy decision making. A family systems perspective can provide a useful lens through which to understand the dynamics of proxy decision making. This article considers the mutual impact of family systems on the processes and outcomes of proxy decision making. The article first reviews medical decision science's evolution and focus on proxy decision making and then reviews a family systems approach, giving particular attention to Rolland's Family Systems Illness Model. A case illustrates how clinical practice and how research would benefit from bringing family systems thinking to proxy decisions. We recommend including a family systems approach in medical decision science research and clinical practices around proxy decisions making. We propose that clinical decisions could be less conflicted and less emotionally troubling for families and clinicians if family systems approaches were included. This perspective opens new directions for research and novel approaches to clinical care. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Recently, the hospital information systems (HIS) and anesthesia information management systems (AIMS) have been rapidly improved and have been introduced into the clinical practice in Japan drastically; however, few reports have detailed their influences on clinical practice. We here report our experience. We introduced HIS (EGMAIN-EX, Fujitsu Co., Ltd.) in our preoperative evaluation clinic and in the postoperative care unit. AIMS (ORSYS, Philips Electronics Japan) was introduced almost only to the intraoperative management. It became easy for us to acquire patient's information and to share it with the medical staffs in the other departments. However, we had to invest large human resources for the introduction and maintenance of the HIS and the AIMS. Though AIMS is more useful in anesthetic management than HIS, it seems to be more suitable for coordination with the medical staffs in the other departments to use HIS for perioperative management than to use AIMS.

    We coordinated anatomy and physiology lectures and practicals to facilitate an integrated understanding of morphology and function in a basic medical science program for dental students and to reduce the time spent on basic science education. This method is a means to provide the essential information and skills in less time. The overall impression was that the practice of joint central nervous system lectures and practicals was an efficient method for students, which suggests that joint lectures might also be useful for clinical subjects. About two-thirds of students felt that the joint anatomy and physiology lecture on the central nervous system was useful and necessary in understanding the relationship between morphology and function, at least for this subject. One-third of students were neutral on the effectiveness of this method. However, the survey results suggest that improvements are needed in the method and timing of joint lectures and practicals. The present teaching approach can be further improved by conducting combined lectures in which the form and function of anatomic structures are presented by the relevant departments during the same lecture. Finally, joint lecturers and practicals offer an opportunity to increase student understanding of the importance of new research findings by the present authors and other researchers.

    Traditional agriculture in rainfed uplands of India has been experiencing low agricultural productivity as the lands suffer from poor soil fertility, susceptibility to water erosion and other external pressures of development and climate change. A shift toward more sustainable cropping systems such as conservation agriculture production systems (CAPSs) may help in maintaining soil quality as well as improving crop production and farmer’s net economic benefit. This research assessed the effects over 3 years (2011–2014) of reduced tillage, intercropping, and cover cropping practices customized for maize-based production systems in upland areas of Odisha, India. The study focused on crop yield, system productivity and profitability through maize equivalent yield and dominance analysis. Results showed that maize grain yield did not differ significantly over time or among CAPS treatments while cowpea yield was considered as an additional yield in intercropping systems. Mustard and horsegram grown in plots after maize cowpea intercropping recorded higher grain yields of 25 and 37%, respectively, as compared to those without intercropping. Overall, the full CAPS implementation, i.e., minimum tillage, maize–cowpea intercropping and mustard residue retention had significantly higher system productivity and net benefits than traditional farmer practices, i.e., conventional tillage, sole maize cropping, and no mustard residue retention. The dominance analysis demonstrated increasing benefits of combining conservation practices that exceeded thresholds for farmer adoption. Given the use of familiar crops and technologies and the magnitude of yield and income improvements, these types of CAPS should be acceptable and attractive for smallholder farmers in the area. This in turn should support a move toward sustainable intensification of crop production to meet future household income and nutritional needs. PMID:27471508

    The development of Real Time Locating Systems has become an important add-on to many existing location aware systems. While Global Navigation Satelite System has solved most of the outdoor problems, it fails to repeat this success indoors. Wireless indoor positioning systems have become very popular in recent years. One of them is UBISENSE system. This system requires to carry an identity tag that is detected by sensors, which typically use triangulation to determine location. This paper presents the results of the investigation of accuracy of tag position using precise geodetic measurements and geometric analysis. Experimental measurements were carried out on the field polygon using precise tacheometer TCRP 1201+ and complete equipment of Ubisense. Results of experimental measurements were analyzed and presented graphically using Surfer 8. The paper presents the results of the investigation the teoretical and practical positioning accuracy according to the various working conditions.

  17. Energy Efficiency Maximization of Practical Wireless Communication Systems

    NASA Astrophysics Data System (ADS)

    Eraslan, Eren

    Energy consumption of the modern wireless communication systems is rapidly growing due to the ever-increasing data demand and the advanced solutions employed in order to address this demand, such as multiple-input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) techniques. These MIMO systems are power hungry, however, they are capable of changing the transmission parameters, such as number of spatial streams, number of transmitter/receiver antennas, modulation, code rate, and transmit power. They can thus choose the best mode out of possibly thousands of modes in order to optimize an objective function. This problem is referred to as the link adaptation problem. In this work, we focus on the link adaptation for energy efficiency maximization problem, which is defined as choosing the optimal transmission mode to maximize the number of successfully transmitted bits per unit energy consumed by the link. We model the energy consumption and throughput performances of a MIMO-OFDM link and develop a practical link adaptation protocol, which senses the channel conditions and changes its transmission mode in real-time. It turns out that the brute force search, which is usually assumed in previous works, is prohibitively complex, especially when there are large numbers of transmit power levels to choose from. We analyze the relationship between the energy efficiency and transmit power, and prove that energy efficiency of a link is a single-peaked quasiconcave function of transmit power. This leads us to develop a low-complexity algorithm that finds a near-optimal transmit power and take this dimension out of the search space. We further prune the search space by analyzing the singular value decomposition of the channel and excluding the modes that use higher number of spatial streams than the channel can support. These algorithms and our novel formulations provide simpler computations and limit the search space into a much smaller set; hence

    NASA Astrophysics Data System (ADS)

    2011-06-01

    The Faraday mirror (FM) plays a very important role in maintaining the stability of two-way plug-and-play quantum key distribution (QKD) systems. However, the practical FM is imperfect, which will not only introduce an additional quantum bit error rate (QBER) but also leave a loophole for Eve to spy the secret key. In this paper we propose a passive Faraday mirror attack in two-way QKD system based on the imperfection of FM. Our analysis shows that if the FM is imperfect, the dimension of Hilbert space spanned by the four states sent by Alice is three instead of two. Thus Eve can distinguish these states with a set of Positive Operator Valued Measure (POVM) operators belonging to three-dimension space, which will reduce the QBER induced by her attack. Furthermore, a relationship between the degree of the imperfection of FM and the transmittance of the practical QKD system is obtained. The results show that the probability that Eve loads her attack successfully depends on the degree of the imperfection of FM rapidly, but the QBER induced by Eve’s attack changes slightly with the degree of the FM imperfection.

    This article describes the architecture of a project aiming to implement a DIN EN ISO 9001 quality management system in a radiological department. It is intended to be a practical guide to demonstrate each step of the project leading to certification of the system. In a planning phase resources for the implementation of the project have to be identified and a quality management (QM) group as core team has to be formed. In the first project phase all available documents have to be checked and compiled in the QM manual. Moreover all relevant processes of the department have to be described in so-called process descriptions. In a second step responsibilities for the project are identified. Customer and employee surveys have to be carried out and a nonconformity management system has to be implemented. In this phase internal audits are also needed to check the new QM system, which is finally tested in the external certification audit with reference to its conformity with the standards.

  20. Comprehensive and Practical Vision System for Self-Driving Vehicle Lane-Level Localization.

    2016-05-01

    Vehicle lane-level localization is a fundamental technology in autonomous driving. To achieve accurate and consistent performance, a common approach is to use the LIDAR technology. However, it is expensive and computational demanding, and thus not a practical solution in many situations. This paper proposes a stereovision system, which is of low cost, yet also able to achieve high accuracy and consistency. It integrates a new lane line detection algorithm with other lane marking detectors to effectively identify the correct lane line markings. It also fits multiple road models to improve accuracy. An effective stereo 3D reconstruction method is proposed to estimate vehicle localization. The estimation consistency is further guaranteed by a new particle filter framework, which takes vehicle dynamics into account. Experiment results based on image sequences taken under different visual conditions showed that the proposed system can identify the lane line markings with 98.6% accuracy. The maximum estimation error of the vehicle distance to lane lines is 16 cm in daytime and 26 cm at night, and the maximum estimation error of its moving direction with respect to the road tangent is 0.06 rad in daytime and 0.12 rad at night. Due to its high accuracy and consistency, the proposed system can be implemented in autonomous driving vehicles as a practical solution to vehicle lane-level localization.

The novel points of the system include a tablet application for facilitating doctor's examination and diagnosis process, a comprehensive eye examination component, and integrated treatment planning and recording. The system provided a new service model through one ophthalmological center linking with multiple remote and rural hospitals for eye care in Guangdong province, China. The early stage of the project study also undertook the responsibility of educations for remote-area doctors and image graders for DR grading and glaucoma grading and research on the effectiveness of short message service (SMS) reminder for patient revisit. Some other research, such as the comparison of the accuracy of graders' DR grading with the gold standard, and doctor's tentative diagnosis with final diagnosis and related statistical information, has been implemented in the system. In the preliminary practice, we summarized the outcomes related to presenting system performance and made an initial analysis. From the practice, the project has shown the telemedicine system and associated contents have satisfied our initial goal and demonstrated their effectiveness and efficiency.

    This paper attempts to study the commercial impact of pumped storage hydro plant on the operation of a stressed power system. The paper further attempts to compute the optimum capacity of the pumped storage scheme that can be provided on commercial basis for a practical power system. Unlike the analysis of commercial aspects of pumped storage scheme attempted in several papers, this paper is presented from the point of view of power system management of a practical system considering the impact of the scheme on the economic operation of the system. A realistic case study is presented as the many factors that influence the pumped storage operation vary widely from one system to another. The suitability of pumped storage for the particular generation mix of a system is well explored in the paper. To substantiate the economic impact of pumped storage on the system, the problem is formulated as a short-term hydrothermal scheduling problem involving power purchase which optimizes the quantum of power to be scheduled and the duration of operation. The optimization model is formulated using an algebraic modeling language, AMPL, which is then solved using the advanced MILP solver CPLEX.

    No previous studies have addressed the integrated relationships among system quality, service quality, job satisfaction, and system performance; this study attempts to bridge such a gap with evidence-based practice study. The convenience sampling method was applied to the information system users of three hospitals in southern Taiwan. A total of 500 copies of questionnaires were distributed, and 283 returned copies were valid, suggesting a valid response rate of 56.6%. SPSS 17.0 and AMOS 17.0 (structural equation modeling) statistical software packages were used for data analysis and processing. The findings are as follows: System quality has a positive influence on service quality (γ11= 0.55), job satisfaction (γ21= 0.32), and system performance (γ31= 0.47). Service quality (β31= 0.38) and job satisfaction (β32= 0.46) will positively influence system performance. It is thus recommended that the information office of hospitals and developers take enhancement of service quality and user satisfaction into consideration in addition to placing b on system quality and information quality when designing, developing, or purchasing an information system, in order to improve benefits and gain more achievements generated by hospital information systems.

    A method by which modern and classical control theory techniques may be integrated in a synergistic fashion and used in the design of practical flight control systems is presented. A general procedure is developed, and several illustrative examples are included. Emphasis is placed not only on the synthesis of the design, but on the assessment of the results as well. The first step is to establish the differences, distinguishing characteristics and connections between the modern and classical control theory approaches. Ultimately, this uncovers a relationship between bandwidth goals familiar in classical control and cost function weights in the equivalent optimal system. In order to obtain a practical optimal solution, it is also necessary to formulate the problem very carefully, and each choice of state, measurement and output variable must be judiciously considered. Once design goals are established and problem formulation completed, the control system is synthesized in a straightforward manner. Three steps are involved: filter-observer solution, regulator solution, and the combination of those two into the controller. Assessment of the controller permits and examination and expansion of the synthesis results.

    Tobacco is a major cause of preventable illness and death. However, clinician use of an evidence-based guideline for treatment of tobacco use is low. This case study describes the process for conducting a pre-intervention assessment of clinician practices and beliefs regarding treatment of tobacco use. Louisiana State University Health System, one of the largest safety-net public hospital systems in the United States, consists of 10 facilities in population centers across the state of Louisiana. The system serves a large proportion of the state's underinsured and uninsured, low-income, and racial/ethnic minority populations, groups that have high rates of tobacco use. Activities included 1) partnering with hospital administrators to generate support for conducting a clinician assessment, 2) identifying and adapting a survey tool to assess clinicians' practices and beliefs regarding treatment of tobacco use, 3) developing a survey protocol and obtaining approval from the institutional review board, and 4) administering the survey electronically, using the hospital's e-mail system. Existing partnerships and system resources aided survey administration. Use of the hospital's internal e-mail system and distribution of an online survey were effective means to engage clinicians. Following notification, 43.6% of 4,508 clinicians opened their e-mail containing the invitation letter with a Web link to the survey; of these, 83.1% (1,634) completed the survey. Partnering with stakeholders and using existing resources within the health care system are essential to successful implementation of a system-wide survey of clinician practices and beliefs regarding treatment of tobacco use.

    In the era of evidenced based healthcare, nursing is required to demonstrate that care provided by nurses is associated with optimal patient outcomes, and a high degree of quality and safety. The use of standardized nursing terminologies and classification systems are a way that nursing documentation can be leveraged to generate evidence related to nursing practice. Several widely-reported nursing specific terminologies and classifications systems currently exist including the Clinical Care Classification System, International Classification for Nursing Practice(®), Nursing Intervention Classification, Nursing Outcome Classification, Omaha System, Perioperative Nursing Data Set and NANDA International. However, the influence of these systems on demonstrating the value of nursing and the professions' impact on quality, safety and patient outcomes in published research is relatively unknown. This paper seeks to understand the use of standardized nursing terminology and classification systems in published research, using the International Classification for Nursing Practice(®) as a case study. A systematic review of international published empirical studies on, or using, the International Classification for Nursing Practice(®) were completed using Medline and the Cumulative Index for Nursing and Allied Health Literature. Since 2006, 38 studies have been published on the International Classification for Nursing Practice(®). The main objectives of the published studies have been to validate the appropriateness of the classification system for particular care areas or populations, further develop the classification system, or utilize it to support the generation of new nursing knowledge. To date, most studies have focused on the classification system itself, and a lesser number of studies have used the system to generate information about the outcomes of nursing practice. Based on the published literature that features the International Classification for Nursing

  14. A Global Assessment on Climate Research Engaging Indigenous Knowledge Systems and Recommendations for Quality Standards of Research Practice in Indigenous Communities

    Indigenous communities worldwide have maintained their own knowledge systems for millennia informed through careful observation of dynamics of environmental changes. Withstanding centuries of challenges to their rights to maintain and practice these knowledge systems, Indigenous peoples continually speak to a need for quality standards for research in their communities. Although, international and Indigenous peoples' working groups emphasize Indigenous knowledge systems and the communities who hold them as critical resources for understanding and adapting to climate change, there has yet to be a comprehensive, evidence based analysis into how diverse knowledge systems are integrated in scientific studies. Do current research practices challenge or support Indigenous communities in their efforts to maintain and appropriately apply their knowledge systems? This study addresses this question using a systematic literature review and meta-analysis assessing levels of Indigenous community participation and decision-making in all stages of the research process (initiation, design, implementation, analysis, dissemination). Assessment is based on reported quality indicators such as: outputs that serve the community, ethical guidelines in practice (free, prior, and informed consent and intellectual property rights), and community access to findings. These indicators serve to identify patterns between levels of community participation and quality standards in practice. Meta-analysis indicates most climate studies practice an extractive model in which Indigenous knowledge systems are co-opted with minimal participation or decision-making authority from communities who hold them. Few studies report outputs that directly serve Indigenous communities, ethical guidelines in practice, or community access to findings. Studies reporting the most quality indicators were initiated in mutual agreement between Indigenous communities and outside researchers or by communities themselves

    2011-11-01

    In the industrial plants processing highly viscous fluid such as foods or industrial products, it is necessary to remove the metallic wear debris originating from pipe in manufacturing line which triggers quality loss. In this study, we developed a high gradient magnetic separation (HGMS) system which consists of superconducting magnet to remove the metallic wear debris. The magnetic separation experiment and the particle trajectory simulation were conducted with polyvinyl alcohol (PVA) as a model material (viscosity coefficient was 10 Pa s, which is 10,000 times higher than that in water). In order to develop a magnetic separation system for practical use, the particle trajectory simulation by using solenoidal superconducting magnet was conducted, and the possibility of the magnetic separation for removing ferromagnetic stainless steel (SUS) particles in highly viscous fluid of 10 Pa s was indicated. Based on the results, the number of filters to obtain required separation efficiency was examined to design the practical separation system.

     Transparency of economic performance of integrated care systems (IV) is a basic requirement for the acceptance and further development of integrated care. Diverse evaluation methods are used but are seldom openly discussed because of the proprietary nature of the different business models. The aim of this article is to develop a generic model for measuring economic performance of IV interventions.  A catalogue of five quality criteria is used to discuss different evaluation methods -(uncontrolled before-after-studies, control group-based approaches, regression models). On this -basis a best practice model is proposed.  A regression model based on the German morbidity-based risk structure equalisation scheme (MorbiRSA) has some benefits in comparison to the other methods mentioned. In particular it requires less resources to be implemented and offers advantages concerning the relia-bility and the transparency of the method (=important for acceptance). Also validity is sound. Although RCTs and - also to a lesser -extent - complex difference-in-difference matching approaches can lead to a higher validity of the results, their feasibility in real life settings is limited due to economic and practical reasons. That is why central criticisms of a MorbiRSA-based model were addressed, adaptions proposed and incorporated in a best practice model: Population-oriented morbidity adjusted margin improvement model (P-DBV(MRSA)).  The P-DBV(MRSA) approach may be used as a standardised best practice model for the economic evaluation of IV. Parallel to the proposed approach for measuring economic performance a balanced, quality-oriented performance measurement system should be introduced. This should prevent incentivising IV-players to undertake short-term cost cutting at the expense of quality. © Georg Thieme Verlag KG Stuttgart · New York.

    2012-02-01

    We present a practically unconditionally gradient stable conservative nonlinear numerical scheme for the N-component Cahn-Hilliard system modeling the phase separation of an N-component mixture. The scheme is based on a nonlinear splitting method and is solved by an efficient and accurate nonlinear multigrid method. The scheme allows us to convert the N-component Cahn-Hilliard system into a system of N-1 binary Cahn-Hilliard equations and significantly reduces the required computer memory and CPU time. We observe that our numerical solutions are consistent with the linear stability analysis results. We also demonstrate the efficiency of the proposed scheme with various numerical experiments.

  20. Managing health and safety risks: Implications for tailoring health and safety management system practices.

    2016-01-01

    As national and international health and safety management system (HSMS) standards are voluntarily accepted or regulated into practice, organizations are making an effort to modify and integrate strategic elements of a connected management system into their daily risk management practices. In high-risk industries such as mining, that effort takes on added importance. The mining industry has long recognized the importance of a more integrated approach to recognizing and responding to site-specific risks, encouraging the adoption of a risk-based management framework. Recently, the U.S. National Mining Association led the development of an industry-specific HSMS built on the strategic frameworks of ANSI: Z10, OHSAS 18001, The American Chemistry Council's Responsible Care, and ILO-OSH 2001. All of these standards provide strategic guidance and focus on how to incorporate a plan-do-check-act cycle into the identification, management and evaluation of worksite risks. This paper details an exploratory study into whether practices associated with executing a risk-based management framework are visible through the actions of an organization's site-level management of health and safety risks. The results of this study show ways that site-level leaders manage day-to-day risk at their operations that can be characterized according to practices associated with a risk-based management framework. Having tangible operational examples of day-to-day risk management can serve as a starting point for evaluating field-level risk assessment efforts and their alignment to overall company efforts at effective risk mitigation through a HSMS or other processes.

    Venipunctures to draw blood for diagnostics can be cumbersome. Multiple puncture attempts are distressing, painful and traumatic, especially for small children. Drawing blood from babies, in particular, is a problem, due to the cutaneous baby fat, tiny veins and, worst case, a pigmented skin. We developed a practical vein viewing system based on IR translumination that, contrary to commercial systems available, has the advantage of: a) low cost, b) easily implemented in routine practice, c) normal and IR image simultaneously available, d) small add-on, e) child friendly IR illuminator and f) efficient IR light coupling. Before introducing the vessel viewer for clinical application in the children's department, parameters were measured in 194 patients (age 0-17 yrs): time to draw blood, number of attempts, skin characteristics, discomfort of patient, and experience of nurse. In this control group, time to draw blood increases significantly with decreasing age of the children. The instant feedback from the nurses has been valuable for the improvements of especially the illumination sources. A clinical trial has been performed in 125 patients (age 0-6 yrs) to prove effectivity of the system in the blood withdrawal procedure. There was a significant decrease from 13% to 2% in failure rate. Also time needed to search for a vein was significantly decreased. A practical and accessible vein viewing system has been developed and is being introduced for clinical application. Although the concept of patient friendliness is already accepted, measurements need to show the effectiveness for particular groups of patients.

    2011-11-01

    Healthcare transition (HCT) for youth with disabilities is a complex phenomenon influenced by multiple interacting factors, including health, personal and environmental factors. Current research on the transition to adulthood for disabled youth has primarily focused on identifying these multilevel factors to guide the development of interventions to improve the HCT process. However, little is known about how this complex array of factors interacts and contributes to successful HCT. Systems thinking provides a theoretically informed perspective that accounts for complexity and can contribute to enhanced understanding of the interactions among HCT factors. The objective of this paper is to introduce general concepts of systems thinking as applied to HCT practice and research. Several systems thinking concepts and principles are introduced and a discussion of HCT as a complex system is provided. Systems dynamics methodology is described as one systems method for conceptualizing HCT. A preliminary systems dynamics model is presented to facilitate discourse on the application of systems thinking principles to HCT practice, policy and research. An understanding of the complex interactions and patterns of relationships in HCT can assist health policy makers and practitioners in determining key areas of intervention, the impact of these interventions on the system and the potential intended and unintended consequences of change. This paper provides initial examination of applying systems thinking to inform future research and practice on HCT. © 2011 Blackwell Publishing Ltd.

    Mark Carroll examines the concept of advanced nursing practice and highlights a number of the difficulties in assessing and defining different levels of practice. Some of the differences and similarities between advanced practice in the US and UK are compared and contrasted. Issues of élitism and the lack of correlation between the needs of the healthcare system and professional self-interest prevent the advancement of specialist roles in the UK. The continuing focus of local trusts on the medicalisation of roles to meet the demands of the healthcare system appears to ignore the need for nursing to expand from within the profession.

    The Canadian Cancer Society and the National Cancer Institute of Canada have charged their Centre for Behavioral Research and Program Evaluation with contributing to the development of the country’s systemic capacity to link research, policy, and practice related to population-level interventions. Local data collection and feedback systems are integral to this capacity. Canada’s School Health Action Planning and Evaluation System (SHAPES) allows data to be collected from all of a school’s students, and these data are used to produce computer-generated school “health profiles.” SHAPES is being used for intervention planning, evaluation, surveillance, and research across Canada. Strong demand and multipartner investment suggest that SHAPES is adding value in all of these domains. Such systems can contribute substantially to evidence-informed public health practice, public engagement, participatory action research, and relevant, timely population intervention research.

    I lead a small practice in rural western North Carolina. We have embraced the patient-centered medical home model and other practice-improvement initiatives, and I have seen our practice transformed in many positive ways. But in the past year alone, my staff and I have spent hundreds of hours studying for and taking exams, certifying for numerous programs, and updating our electronic health records system (EHR) to meet new national requirements and then relearning our EHR. Seeing patients used to be the hardest part of my job. It is now the easiest by far. I am considering walking away from the time-intensive PCMH certification even though it would cause financial hardship. We have more important business at hand-taking excellent care of patients, improving our practice, and meaningfully engaging with our patients. © 2015 Annals of Family Medicine, Inc.

    Utah is among a group of Western Mountain states in which suicide rates among youths are consistently high. The Utah Youth Suicide Study incorporated data from every government agency in Utah, utilizing a statewide Office of the Medical Examiner. A key finding was that 63% of suicide decedents had contact with the juvenile courts. The group developed a best practices model within the juvenile court system for early mental health intervention. Significant cost savings were demonstrated. The model includes screening at-risk teenagers with the Youth Outcome Questionnaire. Treatment includes both psychiatric care and in-home behavioral intervention. Services were effectively delivered on a large scale.

    Sustainable agriculture encompasses economic, environmental, and social aspects of the food system. Members of the Academy of Nutrition and Dietetics (Academy) play an important role in promoting sustainable agriculture because they work in areas where they can influence the food purchasing decisions of foodservice operations and the public. To investigate behavior of registered dietitian nutritionists (RDNs) toward incorporating sustainable agriculture principles into professional practice using the Theory of Planned Behavior. This cross-sectional study surveyed RDNs nationwide about their perspectives on incorporating sustainable agriculture issues into practice. The survey questions were based on a survey originally administered to Minnesota RDNs during 2002. The sample (N=626) was drawn from a randomly selected, national sample of Academy members. Data were analyzed using descriptive statistics, independent t tests, Pearson correlations, and stepwise regression. The sample was mostly white, female, and the average age was 45.4±12.2 years. Almost half of Academy RDNs (47%) reported incorporating environmental issues into their practice. All four Theory of Planned Behavior variables (intention, attitude, perceived behavior control, and subjective norm) were predictive of behavior to include sustainable agriculture issues into practice. Barriers to incorporating this topic into practice included lack of knowledge, ability, time, and employer support. This study found that most of the RDN respondents had heard of sustainable agriculture and nearly half reported including this topic in their professional practice. To integrate this topic into practice more consistently, RDNs need more knowledge, time, and employer support. Copyright © 2017 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

    We propose a method for the fair and efficient allocation of wireless resources over a cognitive radio system network to transmit multiple scalable video streams to multiple users. The method exploits the dynamic architecture of the Scalable Video Coding extension of the H.264 standard, along with the diversity that OFDMA networks provide. We use a game-theoretic Nash Bargaining Solution (NBS) framework to ensure that each user receives the minimum video quality requirements, while maintaining fairness over the cognitive radio system. An optimization problem is formulated, where the objective is the maximization of the Nash product while minimizing the waste of resources. The problem is solved by using a Swarm Intelligence optimizer, namely Particle Swarm Optimization. Due to the high dimensionality of the problem, we also introduce a dimension-reduction technique. Our experimental results demonstrate the fairness imposed by the employed NBS framework.

    Although there are numerous studies of the factors influencing the adoption of quality assurance (QA) programs by medical group practices, few have focused on the role of group practice administrators. To gain insights into the role these administrators play in QA programs, we analyzed how medical practices adopted and implemented the Medicare Physician Quality Reporting System (PQRS), the largest physician quality reporting system in the United States. We conducted focus group interviews in 2011 with a national convenience sample of 76 medical group practice administrators. Responses were organized and analyzed using the innovation decision framework of Van de Ven and colleagues. Administrators conducted due diligence on PQRS, influenced how the issue was presented to physicians for adoption, and managed implementation thereafter. Administrators' recommendations were heavily influenced by practice characteristics, financial incentives, and practice commitments to early adoption of quality improvement innovations. Virtually, all who attempted it agreed that PQRS was straightforward to implement. However, the complexities of Medicare's PQRS reports impeded use of the data by administrators to support quality management. Group practice administrators are playing a prominent role in activities related to the quality of patient care--they are not limited to the business side of the practice. Especially, as PQRS becomes more nearly universal after 2014, Medicare should take account of the role that administrators play, by more actively engaging administrators in shaping these programs and making it easier for administrators to use the results. More research is needed on the rapidly evolving role of nonphysician administration in medical group practices. Practice administrators have a larger role than commonly understood in how quality reporting initiatives are adopted and used and are in an exceptional position to influence the more appropriate use of these resources if

    NASA is currently developing the next generation crewed spacecraft and launch vehicle for exploration beyond earth orbit including returning to the Moon and making the transit to Mars. Managing the design integration of major hardware elements of a space transportation system is critical for overcoming both the technical and programmatic challenges in taking a complex system from concept to space operations. An established method of accomplishing this is formal interface management. In this paper we set forth an argument that the interface management process implemented by NASA between the Orion Multi-Purpose Crew Vehicle (MPCV) and the Space Launch System (SLS) achieves the Level 3 tier of the EIA 731.1 System Engineering Capability Model (SECM) for Generic Practices. We describe the relevant NASA systems and associated organizations, and define the EIA SECM Level 3 Generic Practices. We then provide evidence for our compliance with those practices. This evidence includes discussions of: NASA Systems Engineering Interface (SE) Management standard process and best practices; the tailoring of that process for implementation on the Orion to SLS interface; changes made over time to improve the tailored process, and; the opportunities to take the resulting lessons learned and propose improvements to our institutional processes and best practices. We compare this evidence against the practices to form the rationale for the declared SECM maturity level.

    The Institute of Medicine, through its landmark report concerning errors in medicine, suggests that standardization of practice through systematic development and implementation of evidence-based clinical pathways is an effective way of reducing errors in emergency systems. The specialty of emergency medicine is well positioned to develop a complete system of innovative quality improvement, incorporating best practice guidelines with performance measures and practitioner feedback mechanisms to reduce errors and therefore improve quality of care. This article reviews the construction, ongoing development, and initial impact of such a system at a large, urban, university teaching hospital and at 2 affiliated community hospitals. The Committee for Procedural Quality and Evidence-Based Practice was formed within the Department of Emergency Medicine to establish evidence-based guidelines for nursing and provider care. The committee measures the effect of such guidelines, along with other quality measures, through pre- and postguideline patient care medical record audits. These measures are fed back to the providers in a provider-specific, peer-matched "scorecard." The Committee for Procedural Quality and Evidence-Based Practice affects practice and performance within our department. Multiple physician and nursing guidelines have been developed and put into use. Using asthma as an example, time to first nebulizer treatment and time to disposition from the emergency department decreased. Initial therapeutic agent changed and documentation improved. A comprehensive, guideline-driven, evidence-based approach to clinical practice is feasible within the structure of a department of emergency medicine. High-level departmental support with dedicated personnel is necessary for the success of such a system. Internet site development (available at http://www.CPQE.com) for product storage has proven valuable. Patient care has been improved in several ways; however, consistent and

    Given that clinicians presented with identical clinical information will act in different ways, there is a need to introduce into routine clinical practice methods and tools to support the scientific homogeneity and accountability of healthcare decisions and actions. The benefits expected from such action include an overall reduction in cost, improved quality of care, patient and public opinion satisfaction. Computer-based medical data processing has yielded methods and tools for managing the task away from the hospital management level and closer to the desired disease and patient management level. To this end, advanced applications of information and disease process modelling technologies have already demonstrated an ability to significantly augment clinical decision making as a by-product. The wide-spread acceptance of evidence-based medicine as the basis of cost-conscious and concurrently quality-wise accountable clinical practice suffices as evidence supporting this claim. Electronic libraries are one-step towards an online status of this key health-care delivery quality control environment. Nonetheless, to date, the underlying information and knowledge management technologies have failed to be integrated into any form of pragmatic or marketable online and real-time clinical decision making tool. One of the main obstacles that needs to be overcome is the development of systems that treat both information and knowledge as clinical objects with same modelling requirements. This paper describes the development of such a system in the form of an intelligent clinical information management system: a system which at the most fundamental level of clinical decision support facilitates both the organised acquisition of clinical information and knowledge and provides a test-bed for the development and evaluation of knowledge-based decision support functions.

    This paper describes how the Melbourne East General Practice Network supports general practice to enable quality of care, it describes the challenges and enablers of change, and the evidence of practice capacity building and improved quality of care. Primary care is well known as a place where quality, relatively inexpensive medical care occurs. General practice is made up of multiple small sites with fragmented systems and a funding system that challenges a whole-of-practice approach to clinical care. General Practice Networks support GPs to synthesise complexity and crystallise solutions that enhance general practice beyond current capacity. Through a culture of change management, GP Networks create the link between the practice and the big picture of the whole health system and reduce the isolation of general practice. They distribute information (evidence-based learning and resources) and provide individualised support, responding to practice need and capacity.

  19. Managing soil microbial communities in grain production systems through cropping practices

    2013-04-01

    Cropping practices can significantly influence the composition and activity of soil microbial communities with consequences to plant growth and production. Plant type can affect functional capacity of different groups of biota in the soil surrounding their roots, rhizosphere, influencing plant nutrition, beneficial symbioses, pests and diseases and overall plant health and crop production. The interaction between different players in the rhizosphere is due to the plethora of carbon and nutritional compounds, root-specific chemical signals and growth regulators that originate from the plant and are modulated by the physico-chemical properties of soils. A number of plant and environmental factors and management practices can influence the quantity and quality of rhizodeposition and in turn affect the composition of rhizosphere biota communities, microbe-fauna interactions and biological processes. Some of the examples of rhizosphere interactions that are currently considered important are: proliferation of plant and variety specific genera or groups of microbiota, induction of genes involved in symbiosis and virulence, promoter activity in biocontrol agents and genes correlated with root adhesion and border cell quality and quantity. The observation of variety-based differences in rhizodeposition and associated changes in rhizosphere microbial diversity and function suggests the possibility for the development of varieties with specific root-microbe interactions targeted for soil type and environment i.e. designer rhizospheres. Spatial location of microorganisms in the heterogeneous field soil matrix can have significant impacts on biological processes. Therefore, for rhizosphere research to be effective in variable seasonal climate and soil conditions, it must be evaluated in the field and within a farming systems context. With the current focus on security of food to feed the growing global populations through sustainable agricultural production systems there is a

    The novel "femtocell" in Heterogeneous Network (HetNet) for LTE-Advanced (LTE-A) set-up will allow Malaysian wireless telecommunication operators (Maxis, Celcom, Digi, U-Mobile, P1, YTL and etc2.) to extend connectivity coverage where access would otherwise be limited or unavailable, particularly indoors of large building complexes. A femtocell is a small-sized cellular base station that encompasses all the functionality of a typical station. It therefore allows a simpler and self-contained deployment including private residences. For the Malaysian service providers, the main attractions of femtocell usage are the improvements to both coverage and capacity. The operators can provide a better service to end-users in turn reduce much of the agitations and complaints. There will be opportunity for new services at reduced cost. In addition, the operator not only benefits from the improved capacity and coverage but also can reduce both capital expenditure and operating expense i.e. alternative to brand new base station or macrocell installation. Interference is a key issue associated with femtocell development. There are a large number of issues associated with interference all of which need to be investigated, identified, quantified and solved. This is to ensure that the deployment of any femtocells will take place successfully. Among the most critical challenges in femtocell deployment is the interference between femtocell-to-macrocell and femtocell-to-femtocell in HetNets. In this paper, all proposed methods and algorithms will be investigated in the OFDMA femtocell system considering HetNet scenarios for LTE-A.

    There is a dearth of literature on priority setting and resource allocation (PSRA) practices in hospitals, particularly in low and middle income countries (LMICs). Using a case study approach, we examined PSRA practices in 2 public hospitals in coastal Kenya. We collected data through a combination of in-depth interviews of national level policy makers, hospital managers, and frontline practitioners in the case study hospitals (n = 72), review of documents such as hospital plans and budgets, minutes of meetings and accounting records, and non-participant observations of PSRA practices in case study hospitals over a period of 7 months. In this paper, we apply complex adaptive system (CAS) theory to examine the factors that influence PSRA practices. We found that PSRA practices in the case hospitals were influenced by, 1) inadequate financing level and poorly designed financing arrangements, 2) limited hospital autonomy and decision space, and 3) inadequate management and leadership capacity in the hospital. The case study hospitals exhibited properties of complex adaptive systems (CASs) that exist in a dynamic state with multiple interacting agents. Weaknesses in system 'hardware' (resource scarcity) and 'software' (including PSRA guidelines that reduced hospitals decision space, and poor leadership skills) led to the emergence of undesired properties. The capacity of hospitals to set priorities should be improved across these interacting aspects of the hospital organizational system. Interventions should however recognize that hospitals are CAS. Rather than rectifying isolated aspects of the system, they should endeavor to create conditions for productive emergence. Copyright © 2016 The Author(s). Published by Elsevier Ltd..

    To investigate the relationship between performance on the UK Quality and Outcomes Framework pay-for-performance scheme and choice of clinical computer system. Retrospective longitudinal study. Data for 2007-2008 to 2010-2011, extracted from the clinical computer systems of general practices in England. All English practices participating in the pay-for-performance scheme: average 8257 each year, covering over 99% of the English population registered with a general practice. Levels of achievement on 62 quality-of-care indicators, measured as: reported achievement (levels of care after excluding inappropriate patients); population achievement (levels of care for all patients with the relevant condition) and percentage of available quality points attained. Multilevel mixed effects multiple linear regression models were used to identify population, practice and clinical computing system predictors of achievement. Seven clinical computer systems were consistently active in the study period, collectively holding approximately 99% of the market share. Of all population and practice characteristics assessed, choice of clinical computing system was the strongest predictor of performance across all three outcome measures. Differences between systems were greatest for intermediate outcomes indicators (eg, control of cholesterol levels). Under the UK's pay-for-performance scheme, differences in practice performance were associated with the choice of clinical computing system. This raises the question of whether particular system characteristics facilitate higher quality of care, better data recording or both. Inconsistencies across systems need to be understood and addressed, and researchers need to be cautious when generalising findings from samples of providers using a single computing system.

    Four large rural multispecialty group practice systems employ a mix of organizational technologies to provide chronic disease management with measurable impacts on their patient populations and costs. Four technologies-administrative, clinical, information, and social-are proposed as key dimensions for examining disease management programs. The benefits of disease management are recognized by these systems despite marked variability in the organization of the programs. Committees spanning health plans and clinics in the 4 systems and electronic medical records and/or other disease management information systems are important coordinating mechanisms. Increased reliance on nurses for patient education and care coordination in all 4 systems reflects significant extension of clinical and social technologies in the management of patient care. The promise of disease management as offered by these systems and other auspices are considered.

    There has been a growing impetus to bridge the gap between basic science discovery, development of evidence-based practices (EBPs), and the availability and delivery of EBPs in order to improve the public health impact of such practices. To capitalize on factors that support implementation and sustainment of EBPs, it is important to consider that health care is delivered within the outer context of public health systems and the inner context of health care organizations and work groups. Leaders play a key role in determining the nature of system and organizational contexts. This article addresses the role of leadership and actions that leaders can take at and across levels in developing a strategic climate for EBP implementation within the outer (i.e., system) and inner (i.e., organization, work group) contexts of health care. Within the framework of Edgar Schein's "climate embedding mechanisms," we describe strategies that leaders at the system, organization, and work group levels can consider and apply to develop strategic climates that support the implementation and sustainment of EBP in health care and allied health care settings.

    2017-01-23

    The potential of systems science concepts to inform approaches for addressing complex public health problems, such as obesity prevention, has been attracting significant attention over the last decade. Despite its recent popularity, there are very few studies examining the application of systems science concepts, termed systems thinking, in practice and whether (if at all) it influences the implementation of health promotion in real world settings and in what ways. Healthy Together Victoria (HTV) was based on a systems thinking approach to address obesity prevention alongside other chronic health problems and was implemented across 14 local government areas. This paper examines the experience of practitioners from one of those intervention sites. In-depth interviews with eight practitioners revealed that there was a rigidity with which they had experienced previous health promotion jobs relative to the flexibility and fluidity of HTV. While the health promotion literature does not indicate that health promotion should be overly prescriptive, the experience of these practitioners suggests it is being applied as such in real world settings. Within HTV, asking people to work with 'systems thinking', without giving a prescription about what systems thinking is, enabled practitioners to be 'practice entrepreneurs' by choosing from a variety of systems thinking methods (mapping, reflection) to engage actively in their positions. This highlights the importance of understanding how key concepts, both traditional planning approaches and systems science concepts, are interpreted and then implemented in real world settings. © The Author 2017.

    The huge amount of information that needs to be assimilated in order to keep pace with the continued advances in modern medical practice can form an insurmountable obstacle to the individual clinician. Within radiology, the recent development of quantitative imaging techniques, such as perfusion imaging, and the development of imaging-based biomarkers in modern therapeutic assessment has highlighted the need for computer systems to provide the radiological community with support for academic as well as clinical/translational applications. This article provides an overview of the underlying design and functionality of radiological decision support systems with examples tracing the development and evolution of such systems over the past 40 years. More importantly, we discuss the specific design, performance and usage characteristics that previous systems have highlighted as being necessary for clinical uptake and routine use. Additionally, we have identified particular failings in our current methodologies for data dissemination within the medical domain that must be overcome if the next generation of decision support systems is to be implemented successfully.

    The contribution into activities connected with the development of the quality of nursing care is closely combined with the process of systematic recording of accumulated data, of undertaken activities and achieved results. This in turn constitutes the essence of the 31st Aim of WHO which speaks not only about the need to continue the rational contribution towards the increase in the nursing care quality but also the application of adequate computer technologies to improve this quality. The aim of this work is to demonstrate the scope and character of the activities that have been over years undertaken by the nursing community towards the development of the classification systems which are comparable with those used in medicine. The focus has been specifically put on the taxonomy of diagnosis used by the North American Nursing Diagnosis Association (NANDA) and the European International Classification of Nursing Practice (ICNP). The analysis of the reference sources constitutes the methodological foundation applied in this work. It has allowed to show the pioneering contribution of the American Nursing Association (ANA) into the process of recording and coding of the data that are essential in care delivery as well as their value for the development of ICNP. The latter one is a systematic and multi-axial structure which uses unified terminology and numeric codes for the three categories of variables: the recognized conditions, the undertaken activities and the achieved results.

    2013-01-01

    The functionality of bare polylactide-co-glycolide (PLGA) nanoparticles is limited to drug depot or drug solubilization in their hard cores. They have inherent weaknesses as a drug-delivery system. For instance, when administered intravenously, the nanoparticles undergo rapid clearance from systemic circulation before reaching the site of action. Furthermore, plain PLGA nanoparticles cannot distinguish between different cell types. Recent research shows that surface functionalization of nanoparticles and development of new nanoparticulate dosage forms help overcome these delivery challenges and improve in vivo performance. Immense research efforts have propelled the development of diverse functional PLGA-based nanoparticulate delivery systems. Representative examples include PEGylated micelles/nanoparticles (PEG, polyethylene glycol), polyplexes, polymersomes, core-shell-type lipid-PLGA hybrids, cell-PLGA hybrids, receptor-specific ligand-PLGA conjugates, and theranostics. Each PLGA-based nanoparticulate dosage form has specific features that distinguish it from other nanoparticulate systems. This review focuses on fundamental concepts and practices that are used in the development of various functional nanoparticulate dosage forms. We describe how the attributes of these functional nanoparticulate forms might contribute to achievement of desired therapeutic effects that are not attainable using conventional therapies. Functional PLGA-based nanoparticulate systems are expected to deliver chemotherapeutic, diagnostic, and imaging agents in a highly selective and effective manner.

    2012-05-01

    By 2011 more than half of all office-based physicians were using electronic health record systems, but only about one-third of those physicians had systems with basic features such as the abilities to record information on patient demographics, view laboratory and imaging results, maintain problem lists, compile clinical notes, or manage computerized prescription ordering. Basic features are considered important to realize the potential of these systems to improve health care. We found that although trends in adoption of electronic health record systems across geographic regions converged from 2002 through 2011, adoption continued to lag for non-primary care specialists, physicians age fifty-five and older, and physicians in small (1-2 providers) and physician-owned practices. Federal policies are specifically aimed at encouraging primary care providers and small practices to achieve widespread use of electronic health records. To achieve their nationwide adoption, federal policies may also have to focus on encouraging adoption among non-primary care specialists, as well as addressing persistent gaps in the use of electronic record systems by practice size, physician age, and ownership status.

    The purpose of this clinical concepts paper is to describe the development, implementation, and evaluation of a formal academic-practice partnership between a large, urban, public school system and a college of nursing, based on the American Association of Colleges of Nursing's Guiding Principles to Academic-Practice Partnerships. The overarching goal of the partnership was to increase the school district's capacity to meet sexual health education policy requirements while providing graduate nursing students with an opportunity to work with a diverse population of youth during a public health nursing practicum course. As a result of the partnership, over 2,000 public school students (grades 5-12) have received comprehensive sexual health education and increased their knowledge by an average of 19.7-32.7%. In addition, 79 prelicensure, graduate nursing students have been placed at the public school system for public health nursing practicum and 100% have met all clinical objectives. As with any partnership, successes and lessons learned were identified. Discussion of both is included in this paper and may benefit other organizations considering entering into similar partnerships. Ultimately, academic-practice partnerships are an important mechanism to simultaneously meet the growing needs of community practice partners and nursing education programs, while strengthening public health nursing practice. © 2018 Wiley Periodicals, Inc.

    2012-10-16

    Indicators are needed to assess both socioeconomic and environmental sustainability of bioenergy systems. Effective indicators can help to identify and quantify the sustainability attributes of bioenergy options. We identify 16 socioeconomic indicators that fall into the categories of social well-being, energy security, trade, profitability, resource conservation, and social acceptability. The suite of indicators is predicated on the existence of basic institutional frameworks to provide governance, legal, regulatory and enforcement services. Indicators were selected to be practical, sensitive to stresses, unambiguous, anticipatory, predictive, calibrated with known variability, and sufficient when considered collectively. The utility of each indicator, methods for its measurement,more » and applications appropriate for the context of particular bioenergy systems are described along with future research needs. Together, this suite of indicators is hypothesized to reflect major socioeconomic effects of the full supply chain for bioenergy, including feedstock production and logistics, conversion to biofuels, biofuel logistics and biofuel end uses. Ten of those 16 indicators are proposed to be the minimum list of practical measures of socioeconomic aspects of bioenergy sustainability. Coupled with locally-prioritized environmental indicators, we propose that these socioeconomic indicators can provide a basis to quantify and evaluate sustainability of bioenergy systems across many regions in which they will be deployed.« less

    In 2005, the Illinois State Mental Health Authority embarked on an initiative to close the gap between research and practice in the children's mental health system. A stakeholder advisory council developed a plan to advance evidence informed practice through policy and program initiatives. A multilevel approach was developed to achieve this objective, which included policy change, stakeholder education, and clinician training. This article focuses on the evidence-informed training process designed following review of implementation research. The training involved in-person didactic sessions and twice-monthly telephone supervision across 6 cohorts of community based clinicians, each receiving 12 months of training. Training content initially included cognitive behavioral therapy and behavioral parent training and was adapted over the years to a practice model based on common element concepts. Evaluation based on provider and parent report indicated children treated by training clinicians generally showed superior outcomes versus both a treatment-as-usual comparison group for Cohorts 1 to 4 and the statewide child population as a whole after 90 days of care for Cohorts 5 to 6. The results indicated primarily moderate to strong effects for the evidence-based training groups. Moving a large public statewide child mental health system toward more effective services is a complex and lengthy process. These results indicate training of community mental health providers in Illinois in evidence-informed practice was moderately successful in positively impacting child-level functional outcomes. These findings also influenced state policy in committing resources to continuing the initiative, even in difficult economic times.

    The purpose of this article was to develop and determine the utility of a compliance form in evaluating and teaching the Accreditation Council for Graduate Medical Education competencies of professionalism, practice-based learning and improvement, and systems-based practice. In 2006, we introduced a 17-item compliance form in an obstetrics and gynecology residency program. The form prospectively monitored residents on attendance at required activities (5 items), accountability of required obligations (9 items), and completion of assigned projects (3 items). Scores were compared to faculty evaluations of residents, resident status as a contributor or a concerning resident, and to the residents' conflict styles, using the Thomas-Kilmann Conflict MODE Instrument. Our analysis of 18 residents for academic year 2007-2008 showed a mean (standard error of mean) of 577 (65.3) for postgraduate year (PGY)-1, 692 (42.4) for PGY-2, 535 (23.3) for PGY-3, and 651.6 (37.4) for PGY-4. Non-Hispanic white residents had significantly higher scores on compliance, faculty evaluations on interpersonal and communication skills, and competence in systems-based practice. Contributing residents had significantly higher scores on compliance compared with concerning residents. Senior residents had significantly higher accountability scores compared with junior residents, and junior residents had increased project completion scores. Attendance scores increased and accountability scores decreased significantly between the first and second 6 months of the academic year. There were positive correlations between compliance scores with competing and collaborating conflict styles, and significant negative correlations between compliance with avoiding and accommodating conflict styles. Maintaining a compliance form allows residents and residency programs to focus on issues that affect performance and facilitate assessment of the ACGME competencies.

    Entry into private practice can be rewarding for nurses who are willing to risk personal, financial, and professional security. Among the problems faced by the nurse in this new role is the administration of the practice, since few, if any, adequate models exist. This article describes the struggle of nurses in one private nursing practice, Creative Health Services, to meet their needs for individual freedom within an organization that is regulated sufficiently to maintain its viability.

    An increasing number of countries are exploring the option of introducing Advanced Practice Nurses (APN), such as Nurse Practitioners (NP), as part of the health care workforce. This is particular relevant in light of the increase of the elderly and chronically ill. It is crucial that this introduction is preceded by an in depth understanding of the concept of advanced practice nursing as well as an analysis of the context. Firstly, a conceptual clarification of Advanced Practice Nurses and Nurse Practitioners is provided. Secondly, a framework is introduced that assists in the analysis of the introduction and development of Advanced Practice Nurse roles in a particular health care system. Thirdly, outcomes research on Advanced Practice Nursing is presented. Argumentation developed using data based papers and policy reports on Advanced Practice Nursing. The proposed framework consists of five drivers: (1) the health care needs of the population, (2) education, (3) workforce, (4) practice patterns and (5) legal and health policy framework. These drivers act synergistically and are dynamic in time and space. Outcomes research shows that nurse practitioners show clinical outcomes similar to or better than those of physicians. Further examples demonstrate favourable outcomes in view of the six Ds of outcome research; death, disease, disability, discomfort, dissatisfaction and dollars, for models of care in which Advanced Practice Nurses play a prominent role. Advanced Practice Nurses such as Nurse Practitioners show potential to contribute favourably to guaranteeing optimal health care. Advanced Practice Nurses will wield the greatest influence on health care by focusing on the most pressing health problems in society, especially the care of the chronically ill.

    2004-01-01

    An AIAA Special Project Report was recently produced by AIAA's Nuclear and Future Flight Propulsion Technical Committee and is currently in peer review. The Report provides recommended design practices for conceptual engineering studies of nuclear fusion space propulsion systems. Discussion and recommendations are made on key topics including design reference missions, degree of technological extrapolation and concomitant risk, thoroughness in calculating mass properties (nominal mass properties, weight-growth contingency and propellant margins, and specific impulse), and thoroughness in calculating power generation and usage (power-flow, power contingencies, specific power). The report represents a general consensus of the nuclear fusion space propulsion system conceptual design community and proposes 15 recommendations. This paper expands on the Report by providing specific examples illustrating how to apply each of the recommendations.

    When mandated as resident competencies in 1999, systems-based practice (SBP) and practice-based learning and improvement (PBLI) were new concepts to many. To describe and evaluate a 4-week clinical elective (Achieving Competence Today-ACT) to teach residents SBP and PBLI. ACT consisted of a four-week active learning course and follow-up teaching experience, guided and supported by web-based materials. The curriculum included readings, scheduled activities, work products including an improvement project, and weekly meetings with a non-expert preceptor. The evaluation used a before-after cross-comparison of ACT residents and their peers. Seventy-eight residents and 42 faculty in 18 US Internal Medicine residency programs participated between 2003 and 2005. RESULTS AND MAIN MEASUREMENTS: All residents and faculty preceptors responded to a knowledge test, survey of attitudes, and self-assessment of competency to do 15 tasks related to SBP/PBLI. All measures were normalized to a 100-point scale. Each program's principal investigator (PI) identified aspects of ACT that were most and least effective in enhancing resident learning. ACT residents' gains in knowledge (4.4 on a 100-point scale) and self-assessed competency (11.3) were greater than controls' (-1.9, -8.0), but changes in attitudes were not significantly different. Faculty preceptors' knowledge scores did not change, but their attitudes became more positive (15.8). PIs found a ready-to-use curriculum effective (rated 8.5 on a 10-point scale). ACT increased residents' knowledge and self-assessment of their own competency and raised faculty's assessment of the importance of residents' learning SBP/PBLI. Faculty content expertise is not required for residents to learn SBP/PBLI.

    During the development of the CMR (Common Metadata Repository) (CMR) for the Earth Observing System Data and Information System (EOSDIS), CSW (Catalog Service for the Web) a number of best practices came to light. Given that the ESIP (Earth Science Information Partners) Discovery Cluster is committed to interoperability and standards in earth data discovery this seemed like a convenient moment to provide Best Practices to the organization in the same way we did for OpenSearch for this widely-used standard.

  17. Software ``Best'' Practices: Agile Deconstructed

    NASA Astrophysics Data System (ADS)

    Fraser, Steven

    Software “best” practices depend entirely on context - in terms of the problem domain, the system constructed, the software designers, and the “customers” ultimately deriving value from the system. Agile practices no longer have the luxury of “choosing” small non-mission critical projects with co-located teams. Project stakeholders are selecting and adapting practices based on a combina tion of interest, need and staffing. For example, growing product portfolios through a merger or the acquisition of a company exposes legacy systems to new staff, new software integration challenges, and new ideas. Innovation in communications (tools and processes) to span the growth and contraction of both information and organizations, while managing the adoption of changing software practices, is imperative for success. Traditional web-based tools such as web pages, document libraries, and forums are not suf ficient. A blend of tweeting, blogs, wikis, instant messaging, web-based confer encing, and telepresence creates a new dimension of communication “best” practices.

    Converting the findings from addictions studies into information actionable by (non-research) treatment programs is important to improving program outcomes. This paper describes the translation of the findings of studies on Patient-Services matching, prediction of patient response to treatment (Expected Treatment Response) and prediction of dropout to provide evidence-based decision support in routine treatment. The findings of the studies and their application to the development of an outcomes management system are described. Implementation issues in a network of addictions treatment programs are discussed. The work illustrates how outcomes management systems can play an important role in translating research into practice. PMID:21324606

    This paper draws on the implementation experience of the South Australian GP Plus Practice Nurse Initiative in order to establish what is needed to support the development of the chronic disease management role of practice nurses. The Initiative was delivered between 2007 and 2010 to recruit, train and place 157 nurses across 147 General Practices in Adelaide. The purpose was to improve chronic disease management in General Practice, by equipping nurses to work as practice nurses who would coordinate care and establish chronic disease management systems. Secondary analysis of qualitative data contained in the Initiative evaluation report, specifically drawing on quarterly project records and four focus groups conducted with practice nurses, practice nurse coordinators and practice nurse mentors. As evidenced by the need to increase the amount of support provided during the implementation of the Initiative, nurses new to General Practice faced challenges in their new role. Nurses described a big learning curve as they dealt with role transition to a new work environment and learning a range of new skills while developing chronic disease management systems. Informants valued the skills development and support offered by the Initiative, however the ongoing difficulties in implementing the role suggested that change is also needed at the level of the Practice. While just over a half of the placement positions were retained, practice nurses expressed concern with having to negotiate the conditions of their employment. In order to advance the role of practice nurses as managers of chronic disease support is needed at two levels. At one level support is needed to assist practice nurses to build their own skills. At the level of the Practice, and in the wider health workforce system, support is also needed to ensure that Practices are organisationally ready to include the practice nurse within the practice team.

    The judgement of skill experience and its levels is ambiguous though it is crucial for decision-making in sport sciences studies. We developed a fuzzy decision support system to classify experience of non-elite distance runners. Two Mamdani subsystems were developed based on expert running coaches’ knowledge. In the first subsystem, the linguistic variables of training frequency and volume were combined and the output defined the quality of running practice. The second subsystem yielded the level of running experience from the combination of the first subsystem output with the number of competitions and practice time. The model results were highly consistent with the judgment of three expert running coaches (r>0.88, p<0.001) and also with five other expert running coaches (r>0.86, p<0.001). From the expert’s knowledge and the fuzzy model, running experience is beyond the so-called "10-year rule" and depends not only on practice time, but on the quality of practice (training volume and frequency) and participation in competitions. The fuzzy rule-based model was very reliable, valid, deals with the marked ambiguities inherent in the judgment of experience and has potential applications in research, sports training, and clinical settings.

    Objectives To examine the effectiveness of the quality management programme—European Practice Assessment—in primary care in Switzerland. Design Longitudinal study with three points of measurement. Setting Primary care practices in Switzerland. Participants In total, 45 of 91 primary care practices completed European Practice Assessment three times. Outcomes The interval between each assessment was around 36 months. A variance analyses for repeated measurements were performed for all 129 quality indicators from the domains: ‘infrastructure’, ‘information’, ‘finance’, and ‘quality and safety’ to examine changes over time. Results Significant improvements were found in three of four domains: ‘quality and safety’ (F=22.81, p<0.01), ‘information’ (F=27.901, p<0.01) and ‘finance’ (F=4.073, p<0.02). The 129 quality indicators showed a significant improvement within the three points of measurement (F=33.864, p<0.01). Conclusions The European Practice Assessment for primary care practices thus provides a functioning quality management programme, focusing on the sustainable improvement of structural and organisational aspects to promote high quality of primary care. The implementation of a quality management system which also includes a continuous improvement process would give added value to provide good care. PMID:25900466

    At the Medical School of Chiba University, educational dissection tours have been conducted for intra- and extramural students in other programs, such as students of nursing. In the 2006 school year there were more than 1,500 students. As presented in a previous report, we tested an educational program in which our medical students teach other students parts of splanchnology, neurology, and myology to promote student understanding of human physiology through their own teaching. Since this system, termed the "teaching assistant system," was fairly laborious for many medical students, we attempted to improve it by decreasing the students' load and reducing the frequency of teaching from several times to once during the one-term dissection practice. We assessed the improved method with questionnaires for medical students who had studied at the school in 2006 and 2007 (n = 206) before and after teaching other students. The response rate for the questionnaires was 91.3% (n = 188). The results were as follows. (1) Most medical students (69.7%) realized that the task of teaching had stimulating effects on their own learning motivation. (2) According to most of their evaluations (80.4%), the duties of teaching involved in the previous assistant system were laborious. In contrast, the ratio of medical students who considered teaching to be laborious decreased by about half (55.3%) in the present improved system. (3) Most students (79.8%) were satisfied with the teaching assistant system. We concluded that the improved teaching assistant system was effective for the dissection practice.

    Pediatric residents learn about systems-based practice (SBP) explicitly in the formal curriculum and implicitly in the informal curriculum as they engage in practice alongside physician faculty. Recent studies describe innovative ways to address SBP in the formal curriculum for SBP, but the informal curriculum has not been explored. We examined what, and how, third-year pediatric residents learn about SBP in the informal curriculum at one continuity clinic, and to consider how this learning aligns with the formal curriculum. A case study involving 10 third-year pediatric residents and 10 continuity preceptors was conducted at one continuity clinic, housed in a community-based, pediatric primary care center. Data were derived from 5 months (100 hours) of direct observation in the precepting room at the case clinic, semistructured interviews with residents (before and after observation) and with preceptors (after observation). Interview transcripts and notes from observation were inductively coded and analyzed for major themes. Two themes emerged in the informal curriculum. Residents perceived "our system," the academic health system in which they trained and practiced as separate and distinct from the "real system," the larger, societal context of health care. Residents also understood SBP as a commitment to helping individual patients and families navigate the complexities of "our system," dealing with issues that concerned them. Residents learn important lessons about SBP in the informal curriculum in continuity clinic. These lessons may reinforce some elements of the competency-based formal curriculum for SBP, but challenge others.

    2005-06-01

    Treatment outcomes and duration of treatment for patients treated in university graduate orthodontic programs and private orthodontic practices were assessed and compared with the ABO objective grading system. The treatment records of 139 randomly selected adolescents who had received comprehensive orthodontic treatment were examined. Seventy-seven subjects had been treated in 3 postgraduate orthodontic clinics, and 62 had been treated in 3 private orthodontic practices. Pretreatment, all subjects had Class II Division 1 malocclusions and ANB angles equal to or greater than 4 degrees . All patients were treated with premolar extractions. Posttreatment dental casts were measured and scored with the ABO objective grading system. No significant differences were found between the groups in the alignment, buccolingual inclination, and overjet components. Patients treated in private practice had significantly lower scores for marginal ridge height and occlusal relationship. Patients treated in the university programs had significantly lower scores for occlusal contact and interproximal contact components. There was no significant difference in the overall score, thus no significant difference in the overall quality of orthodontic treatment outcome between patients treated in university programs and private practices. However, the university group had a significantly larger sample variance for the overall score. There was no significant difference in the duration of the treatment between patients treated in a university setting and in a private practice.

  11. Highly Turbulent Counterflow Flames: A Laboratory Scale Benchmark for Practical Combustion Systems

    NASA Astrophysics Data System (ADS)

    Gomez, Alessandro

    2013-11-01

    Since the pioneering work of Weinberg's group at Imperial College in the `60s, the counterflow system has been the workhorse of laminar flame studies. Recent developments have shown that it is also a promising benchmark for highly turbulent (Ret ~ 1000) nonpremixed and premixed flames of direct relevance to gasturbine combustion. Case studies will demonstrate the versatility of the system in mimicking real flame effects, such as heat loss and flame stratification in premixed flames, and the compactness of the combustion region. The system may offer significant advantages from a computational viewpoint, including: a) aerodynamic flame stabilization near the interface between the two opposed jets, with ensuing simplifications in the prescription of boundary conditions; b) a fiftyfold reduction of the domain of interest as compared to conventional nonpremixed jet flames at the same Reynolds number; and c) millisecond mean residence times, which is particularly useful for DNS/LES computational modeling, and for soot suppression in the combustion of practical fuels.

    Abstract The redefinition of neuropathic pain as “pain arising as a direct consequence of a lesion or disease affecting the somatosensory system,” which was suggested by the International Association for the Study of Pain (IASP) Special Interest Group on Neuropathic Pain (NeuPSIG) in 2008, has been widely accepted. In contrast, the proposed grading system of possible, probable, and definite neuropathic pain from 2008 has been used to a lesser extent. Here, we report a citation analysis of the original NeuPSIG grading paper of 2008, followed by an analysis of its use by an expert panel and recommendations for an improved grading system. As of February, 2015, 608 eligible articles in Scopus cited the paper, 414 of which cited the neuropathic pain definition. Of 220 clinical studies citing the paper, 56 had used the grading system. The percentage using the grading system increased from 5% in 2009 to 30% in 2014. Obstacles to a wider use of the grading system were identified, including (1) questions about the relative significance of confirmatory tests, (2) the role of screening tools, and (3) uncertainties about what is considered a neuroanatomically plausible pain distribution. Here, we present a revised grading system with an adjusted order, better reflecting clinical practice, improvements in the specifications, and a word of caution that even the “definite” level of neuropathic pain does not always indicate causality. In addition, we add a table illustrating the area of pain and sensory abnormalities in common neuropathic pain conditions and propose areas for further research. PMID:27115670

Here, we present a revised grading system with an adjusted order, better reflecting clinical practice, improvements in the specifications, and a word of caution that even the "definite" level of neuropathic pain does not always indicate causality. In addition, we add a table illustrating the area of pain and sensory abnormalities in common neuropathic pain conditions and propose areas for further research.

  14. Organisational development in general practice: lessons from practice and professional development plans (PPDPs)

    Background Improving the quality and effectiveness of clinical practice is becoming a key task within all health services. Primary medical care, as organised in the UK is composed of clinicians who work in independent partnerships (general practices) that collaborate with other health care professionals. Although many practices have successfully introduced innovations, there are no organisational development structures in place that support the evolution of primary medical care towards integrated care processes. Providing incentives for attendance at passive educational events and promoting 'teamwork' without first identifying organisational priorities are interventions that have proved to be ineffective at changing clinical processes. A practice and professional development plan feasibility study was evaluated in Wales and provided the experiential basis for a summary of the lessons learnt on how best to guide organisational development systems for primary medical care. Results Practice and professional development plans are hybrids produced by the combination of ideas from management (the applied behavioural science of organisational development) and education (self-directed adult learning theories) and, in conceptual terms, address the lack of effectiveness of passive educational strategies by making interventions relevant to identified system wide needs. In the intervention, each practice participated in a series of multidisciplinary workshops (minimum 4) where the process outcome was the production of a practice development plan and a set of personal portfolios, and the final outcome was a realised organisational change. It was apparent during the project that organisational admission to a process of developmental planning needed to be a stepwise process, where initial interest can lead to a fuller understanding, which subsequently develops into motivation and ownership, sufficient to complete the exercise.

    An important purpose of formative assessment is to elicit student thinking to use in instruction to help all students learn and inform next steps in teaching. However, formative assessment practices are difficult to implement and thus present a formidable challenge for many science teachers. A critical need in geoscience education is a framework for providing teachers with real-time assessment tools as well as professional development to learn how to use formative assessment to improve instruction. Here, we describe a comprehensive support system, developed for our NSF-funded Contingent Pedagogies project, for addressing the challenge of helping teachers to use formative assessment to enhance student learning in middle school Earth Systems science. Our support system is designed to improve student understanding about the geosphere by integrating classroom network technology, interactive formative assessments, and contingent curricular activities to guide teachers from formative assessment to instructional decision-making and improved student learning. To accomplish this, we are using a new classroom network technology, Group Scribbles, in the context of an innovative middle-grades Earth Science curriculum called Investigating Earth Systems (IES). Group Scribbles, developed at SRI International, is a collaborative software tool that allows individual students to compose “scribbles” (i.e., drawings and notes), on “post-it” notes in a private workspace (a notebook computer) in response to a public task. They can post these notes anonymously to a shared, public workspace (a teacher-controlled large screen monitor) that becomes the centerpiece of group and class discussion. To help teachers implement formative assessment practices, we have introduced a key resource, called a teaching routine, to help teachers take advantage of Group Scribbles for more interactive assessments. Routine refers to a sequence of repeatable interactions that, over time, become

  18. Understanding how orthopaedic surgery practices generate value for healthcare systems.

    2013-06-01

    Orthopaedic surgery practices can provide substantial value to healthcare systems. Increasingly, healthcare administrators are speaking of the need for alignment between physicians and healthcare systems. However, physicians often do not understand what healthcare administrators value and therefore have difficulty articulating the value they create in discussions with their hospital or healthcare organization. Many health systems and hospitals use service lines as an organizational structure to track the relevant data and manage the resources associated with a particular type of care, such as musculoskeletal care. Understanding service lines and their management can be useful for orthopaedic surgeons interested in interacting with their hospital systems. We provide an overview of two basic types of value orthopaedic surgeons create for healthcare systems: financial or volume-driven benefits and nonfinancial quality or value-driven patient care benefits. We performed a search of PubMed from 1965 to 2012 using the term "service line." Of the 351 citations identified, 18 citations specifically involved the use of service lines to improve patient care in both nursing and medical journals. A service line is a structure used in healthcare organizations to enable management of a subset of activities or resources in a focused area of patient care delivery. There is not a consistent definition of what resources are managed within a service line from hospital to hospital. Physicians can positively impact patient care through engaging in service line management. There is increasing pressure for healthcare systems and hospitals to partner with orthopaedic surgeons. The peer-reviewed literature demonstrates there are limited resources for physicians to understand the value they create when attempting to negotiate with their hospital or healthcare organization. To effectively negotiate for resources to provide the best care for patients, orthopaedic surgeons need to claim and

    Pharmacovigilance requirements for biologics mandate that EU Member States shall ensure that any biologic that is the subject of a suspected adverse drug reaction (ADR) is identifiable by brand name and batch number. Recent studies showed that brand name identification is well established, whereas batch numbers are (still) poorly reported. We evaluated information-recording systems and practices in the Dutch hospital setting to identify determinants for brand name and batch number recording as well as success factors and bottlenecks for traceability. We surveyed Dutch hospital pharmacists with an online questionnaire on systems and practices in hospitals for recording brand names and batch numbers. Additionally, we performed an analysis of the traceability of recombinant biologics in spontaneous ADR reports (received between 2009 and 2014) from the Netherlands Pharmacovigilance Centre Lareb. The survey showed that brand names are not routinely recorded in the clinical practice of Dutch hospitals, whereas batch numbers are poorly recorded. Seventy-six percent of the 1523 ADR reports for recombinant biologics had a traceable brand name whereas 5% of these reports contained a batch number. The results suggest a possible relationship between the availability of brand and batch number information in clinical practice and the inclusion of this information in ADR reports for biologics. The limited traceability of brand names and batch numbers in ADR reports may be primarily caused by the shortcomings in the recording of information in clinical practice. We recommend efforts to improve information-recording systems as a first step to improve the traceability of biologics in ADR reporting.

  20. A new practice-driven approach to develop software in a cyber-physical system environment

    2016-02-01

    Cyber-physical system (CPS) is an emerging area, which cannot work efficiently without proper software handling of the data and business logic. Software and middleware is the soul of the CPS. The software development of CPS is a critical issue because of its complicity in a large scale realistic system. Furthermore, object-oriented approach (OOA) is often used to develop CPS software, which needs some improvements according to the characteristics of CPS. To develop software in a CPS environment, a new systematic approach is proposed in this paper. It comes from practice, and has been evolved from software companies. It consists of (A) Requirement analysis in event-oriented way, (B) architecture design in data-oriented way, (C) detailed design and coding in object-oriented way and (D) testing in event-oriented way. It is a new approach based on OOA; the difference when compared with OOA is that the proposed approach has different emphases and measures in every stage. It is more accord with the characteristics of event-driven CPS. In CPS software development, one should focus on the events more than the functions or objects. A case study of a smart home system is designed to reveal the effectiveness of the approach. It shows that the approach is also easy to be operated in the practice owing to some simplifications. The running result illustrates the validity of this approach.

  1. New entrants' practice patterns in Medicare home health care after the prospective payment system revision in 2008.

    Medicare home health care spending increased under the prospective payment system (PPS) that was introduced specifically to control the rising spending. To explain this unexpected spending rise, we focused on new home health agencies that entered the market under the PPS. The high profit margins under the PPS attracted many new agencies to the market partially due to home health care's unique feature of low entry costs. We examined whether new entrants were more likely to adopt the practice patterns leading to higher profit margins than incumbent agencies that had been operating in the market before the PPS. Using 2008 to 2010 Medicare Home Health Claims and Provider of Services File, we estimated regressions of agencies' practice patterns controlling for agency and patient characteristics. We found that new entrants were more likely than incumbents to adopt practice patterns leading to high profit margins. They were more likely to target the 14th and 20th therapy visit where marginal revenue is relatively greater than that of other number of visits. Under the payment system that compensates extra therapy visits but not for other types of visits, entrants were also more likely to provide therapy visits, but less likely to provide medical social service visits. Given the high entry rates of agencies under the PPS, distinct practice patterns among entrants explain the drastic home health spending increase under the PPS. Heterogeneity in agencies' practice patterns also suggests an opportunity to improve efficiency in the Medicare home health care market. Copyright © 2015 Elsevier Inc. All rights reserved.

    2006-01-01

    The Practice Health Atlas (PHA) is a decision support tool for general practice, designed by the Adelaide Western Division of General Practice (AWDGP). This article describes the features of the PHA and its potential role in enhancing health care. In developing the PHA, the AWDGP utilises a range of software tools and consults with a practice to understand its clinical data management approach. The PHA comprises three sections: epidemiology, business and clinical modelling systems, access to services. The objectives include developing a professional culture around quality health data and synthesis of aggregated de-identified general practice data at both practice and divisional level (and beyond) to assist with local health needs assessment, planning, and funding. Evaluation occurs through group feedback sessions and from the general practitioners and staff. It has demonstrated its potential to fulfill the objectives in outcome areas such as data quality and management, team based care, pro-active practice population health care, and business systems development, thereby contributing to improved patient health outcomes.

    This study was conducted to know cropping cycles required to improve OM status in soil and to investigate the effects of medium-term tillage practices on soil properties and crop yields in Grey Terrace soil of Bangladesh under wheat-mungbean-T. aman cropping system. Four different tillage practices, namely, zero tillage (ZT), minimum tillage (MT), conventional tillage (CT), and deep tillage (DT), were studied in a randomized complete block (RCB) design with four replications. Tillage practices showed positive effects on soil properties and crop yields. After four cropping cycles, the highest OM accumulation, the maximum root mass density (0–15 cm soil depth), and the improved physical and chemical properties were recorded in the conservational tillage practices. Bulk and particle densities were decreased due to tillage practices, having the highest reduction of these properties and the highest increase of porosity and field capacity in zero tillage. The highest total N, P, K, and S in their available forms were recorded in zero tillage. All tillage practices showed similar yield after four years of cropping cycles. Therefore, we conclude that zero tillage with 20% residue retention was found to be suitable for soil health and achieving optimum yield under the cropping system in Grey Terrace soil (Aeric Albaquept).

  6. Advancing the application of systems thinking in health: exploring dual practice and its management in Kampala, Uganda

    PubMed Central

    2014-01-01

    Background Many full-time Ugandan government health providers take on additional jobs – a phenomenon called dual practice. We describe the complex patterns that characterize the evolution of dual practice in Uganda, and the local management practices that emerged in response, in five government facilities. An in-depth understanding of dual practice can contribute to policy discussions on improving public sector performance. Methods A multiple case study design with embedded units of analysis was supplemented by interviews with policy stakeholders and a review of historical and policy documents. Five facility case studies captured the perspective of doctors, nurses, and health managers through semi-structured in-depth interviews. A causal loop diagram illustrated interactions and feedback between old and new actors, as well as emerging roles and relationships. Results The causal loop diagram illustrated how feedback related to dual practice policy developed in Uganda. As opportunities for dual practice grew and the public health system declined over time, government providers increasingly coped through dual practice. Over time, government restrictions to dual practice triggered policy resistance and protest from government providers. Resulting feedback contributed to compromising the supply of government providers and, potentially, of service delivery outcomes. Informal government policies and restrictions replaced the formal restrictions identified in the early phases. In some instances, government health managers, particularly those in hospitals, developed their own practices to cope with dual practice and to maintain public sector performance. Management practices varied according to the health manager’s attitude towards dual practice and personal experience with dual practice. These practices were distinct in hospitals. Hospitals faced challenges managing internal dual practice opportunities, such as those created by externally-funded research projects based

  7. Developing geospatial thinking and the science practices of investigation and evalutation with geographic information systems

    Hamilton, Kelli

    Geospatial thinking is a subset of spatial thinking, which has been identified by the National Geography Standards as an essential skill for students to gain through geography instruction (Heffron & Downs, 2013). One tool which has been shown to help students develop their geospatial thinking skills is Geographic Information Systems (GIS) (Kim & Bednraz, 2013; Lee & Bednarz, 2009; Patterson, 2007). Much of the research conducted with GIS has been in the context of social studies classrooms. This study examined the use of GIS with seventh grade students in a science classroom. Results of this study indicate that students who use GIS as part of their science instruction are able to practice geospatial thinking skills. In addition, this study examined how GIS could be used to enhance the instruction of the science practices of investigation and evaluation. The Next Generation Science Standards identify certain science practices which students should experience as part of science instruction (NGSS Lead States, 2013). Among those practices are investigation and evaluation. Students in this study used GIS to investigate and evaluate scientific data. Both the teacher and the students were able to identify ways that GIS enhanced both the investigation and evaluation of data.

  8. How treating the patient with diabetes can enhance your practice: recommendations for practice management.

    PubMed

    Levin, Roger P

    2003-10-01

    The ability of dental practices to remain productive and profitable over time depends on their capacity to serve patients comprehensively. The increasing diversity in the patient population demands that practices customize services to ensure exceptional care for all patients. This diversity is particularly prevalent in patient subpopulations with unique medical conditions and treatment needs, such as patients with diabetes. Proper and effective management of patients with diabetes requires that the practice evaluate all aspects of patient interaction. Systems need to be customized so that all procedures and patient communication scripts are implemented consistently to meet the distinct needs of patients with diabetes. A significant return on investment in customized systems can be realized if the practice implements effective marketing strategies to both attract this population of patients and brand the practice as a unique and specialized service provider.

    Health information systems are becoming common because they are important tools to support decision making and assist nurses in their daily interventions. The Information System for Nursing Practice promotes consistent nursing records, as it is directed to the nursing practice and process. The aims of this study were to identify and describe the most frequent type of nursing actions in the care plan for a patient after acute myocardial infarction, considering the seven-axis model of the International Classification of Nursing Practice and the rate of health education given to patients during hospitalization. A cross-sectional analysis was performed retrospectively by searching the computerized database of the Information System for Nursing Practice. We verified some gaps in information with regard to unidentified records of diagnoses and interventions. During hospitalization, the most used interventions were in the fields of observing (40%) and managing (23%). Interventions associated with management of signs and symptoms were more frequent and were performed in 84.9% of the patients. In the field of informing, health education in relation to diet was performed in 21.7% of the patients; exercise, in 16%; and tobacco, in 11.3%. The use of nursing records and information systems can improve nursing care coordination and care plan management.

    2008-01-01

    Background When mandated as resident competencies in 1999, systems-based practice (SBP) and practice-based learning and improvement (PBLI) were new concepts to many. Objective To describe and evaluate a 4-week clinical elective (Achieving Competence Today—ACT) to teach residents SBP and PBLI. Design ACT consisted of a four-week active learning course and follow-up teaching experience, guided and supported by web-based materials. The curriculum included readings, scheduled activities, work products including an improvement project, and weekly meetings with a non-expert preceptor. The evaluation used a before–after cross-comparison of ACT residents and their peers. Participants Seventy-eight residents and 42 faculty in 18 US Internal Medicine residency programs participated between 2003 and 2005. Results and Main Measurements All residents and faculty preceptors responded to a knowledge test, survey of attitudes, and self-assessment of competency to do 15 tasks related to SBP/PBLI. All measures were normalized to a 100-point scale. Each program’s principal investigator (PI) identified aspects of ACT that were most and least effective in enhancing resident learning. ACT residents’ gains in knowledge (4.4 on a 100-point scale) and self-assessed competency (11.3) were greater than controls’ (−1.9, −8.0), but changes in attitudes were not significantly different. Faculty preceptors’ knowledge scores did not change, but their attitudes became more positive (15.8). PIs found a ready-to-use curriculum effective (rated 8.5 on a 10-point scale). Conclusions ACT increased residents’ knowledge and self-assessment of their own competency and raised faculty’s assessment of the importance of residents’ learning SBP/PBLI. Faculty content expertise is not required for residents to learn SBP/PBLI. PMID:18612719

    PubMed

    Kennedy, Margaret Ann

    2016-01-01

    Evidence-based practice in nursing is considered foundational to safe, competent care. To date, rigid traditional perceptions of what constitutes 'evidence' have constrained the recognition and use of practice-based evidence and the exploitation of novel forms of evidence from data rich environments. Advancements such as the conceptualization of clinical intelligence, the prevalence of increasingly sophisticated digital health information systems, and the advancement of the Big Data phenomenon have converged to generate a new contemporary context. In today's dynamic data-rich environments, clinicians have new sources of valid evidence, and need a new paradigm supporting clinical practice that is adaptive to information generated by diverse electronic sources. This opinion paper presents adaptive practice as the next generation of evidence-based practice in contemporary evidence-rich environments and provides recommendations for the next phase of evolution.

    To examine the effectiveness of the quality management programme--European Practice Assessment--in primary care in Switzerland. Longitudinal study with three points of measurement. Primary care practices in Switzerland. In total, 45 of 91 primary care practices completed European Practice Assessment three times. The interval between each assessment was around 36 months. A variance analyses for repeated measurements were performed for all 129 quality indicators from the domains: 'infrastructure', 'information', 'finance', and 'quality and safety' to examine changes over time. Significant improvements were found in three of four domains: 'quality and safety' (F=22.81, p<0.01), 'information' (F=27.901, p<0.01) and 'finance' (F=4.073, p<0.02). The 129 quality indicators showed a significant improvement within the three points of measurement (F=33.864, p<0.01). The European Practice Assessment for primary care practices thus provides a functioning quality management programme, focusing on the sustainable improvement of structural and organisational aspects to promote high quality of primary care. The implementation of a quality management system which also includes a continuous improvement process would give added value to provide good care. Published by the BMJ Publishing Group Limited.

    For health care reform to succeed, health care systems need a professionally satisfied primary care workforce. Evidence suggests that primary care physicians are less satisfied than those in other medical specialties. To assess three domains of physician satisfaction by area of clinical practice among physicians practicing in an established integrated health system. Cross-sectional online survey of all Southern California Permanente Medical Group (SCPMG) partner and associate physicians (N = 1034) who were primarily providing clinic-based care in 1 of 4 geographically and operationally distinct Kaiser Permanente Southern California Medical Centers. Primary measure was satisfaction with one's day-to-day professional life as a physician. Secondary measures were satisfaction with quality of care and income. Of the 636 physicians responding to the survey (61.5% response rate), on average, 8 in 10 SCPMG physicians reported satisfaction with their day-to-day professional life as a physician. Primary care physicians were only minimally less likely to report being satisfied (difference of 8.2-9.5 percentage points; p < 0.05) than were other physicians. Nearly all physicians (98.2%) were satisfied with the quality of care they are able to provide. Roughly 8 in 10 physicians reported satisfaction with their income. No differences were found between primary care physicians and those in other clinical practice areas regarding satisfaction with quality of care or income. It is possible to create practice settings, such as SCPMG, in which most physicians, including those in primary care, experience high levels of professional satisfaction.

    Objective The purpose of this article was to develop and determine the utility of a compliance form in evaluating and teaching the Accreditation Council for Graduate Medical Education competencies of professionalism, practice-based learning and improvement, and systems-based practice. Methods In 2006, we introduced a 17-item compliance form in an obstetrics and gynecology residency program. The form prospectively monitored residents on attendance at required activities (5 items), accountability of required obligations (9 items), and completion of assigned projects (3 items). Scores were compared to faculty evaluations of residents, resident status as a contributor or a concerning resident, and to the residents' conflict styles, using the Thomas-Kilmann Conflict MODE Instrument. Results Our analysis of 18 residents for academic year 2007–2008 showed a mean (standard error of mean) of 577 (65.3) for postgraduate year (PGY)-1, 692 (42.4) for PGY-2, 535 (23.3) for PGY-3, and 651.6 (37.4) for PGY-4. Non-Hispanic white residents had significantly higher scores on compliance, faculty evaluations on interpersonal and communication skills, and competence in systems-based practice. Contributing residents had significantly higher scores on compliance compared with concerning residents. Senior residents had significantly higher accountability scores compared with junior residents, and junior residents had increased project completion scores. Attendance scores increased and accountability scores decreased significantly between the first and second 6 months of the academic year. There were positive correlations between compliance scores with competing and collaborating conflict styles, and significant negative correlations between compliance with avoiding and accommodating conflict styles. Conclusions Maintaining a compliance form allows residents and residency programs to focus on issues that affect performance and facilitate assessment of the ACGME competencies

    In this paper we develop a novel practical application, which give scalable services to the end users when abnormal actives are happening. Architecture of the application has been presented consisting of network infrared cameras and a communication module. In this intelligent surveillance system we use Kinect sensors as the input cameras. Kinect is an infrared laser camera which its user can access the raw infrared sensor stream. We install several Kinect sensors in one room to track the human skeletons. Each sensor returns the body positions with 15 coordinates in its own coordinate system. We use calibration algorithms to calibrate all the body positions points into one unified coordinate system. With the body positions points, we can infer the surveillance context. Furthermore, the messages from the metadata index matrix will be sent to mobile phone through communication module. User will instantly be aware of an abnormal case happened in the room without having to check the website. In conclusion, theoretical analysis and experimental results in this paper show that the proposed system is reasonable and efficient. And the application method introduced in this paper is not only to discourage the criminals and assist police in the apprehension of suspects, but also can enabled the end-users monitor the indoor environments anywhere and anytime by their phones.

  7. Systems solutions by lactic acid bacteria: from paradigms to practice

    PubMed Central

    2011-01-01

    Lactic acid bacteria are among the powerhouses of the food industry, colonize the surfaces of plants and animals, and contribute to our health and well-being. The genomic characterization of LAB has rocketed and presently over 100 complete or nearly complete genomes are available, many of which serve as scientific paradigms. Moreover, functional and comparative metagenomic studies are taking off and provide a wealth of insight in the activity of lactic acid bacteria used in a variety of applications, ranging from starters in complex fermentations to their marketing as probiotics. In this new era of high throughput analysis, biology has become big science. Hence, there is a need to systematically store the generated information, apply this in an intelligent way, and provide modalities for constructing self-learning systems that can be used for future improvements. This review addresses these systems solutions with a state of the art overview of the present paradigms that relate to the use of lactic acid bacteria in industrial applications. Moreover, an outlook is presented of the future developments that include the transition into practice as well as the use of lactic acid bacteria in synthetic biology and other next generation applications.

    Objectives To examine the current state of the science regarding the role of systemic hydration in vocal function and health. Study Design Literature Review Methods Literature search spanning multiple disciplines, including speech-language pathology, nutrition and dietetics, medicine, sports and exercise science, physiology and biomechanics. Results The relationship between hydration and physical function is an area of common interest amongst multiple professions. Each discipline provides valuable insight into the connection between performance and water balance, as well as complimentary methods of investigation. Existing voice literature suggests a relationship between hydration and voice production, however the underlying mechanisms are not yet defined and a treatment effect for systemic hydration remains to be demonstrated. Literature from other disciplines sheds light on methodological shortcomings and in some cases offers an alternative explanation for observed phenomena. Conclusions A growing body of literature in the field of voice science is documenting a relationship between hydration and vocal function, however greater understanding is required to guide best practice in the maintenance of vocal health and management of voice disorders. Integration of knowledge and technical expertise from multiple disciplines facilitates analysis of existing literature and provides guidance as to future research. PMID:24880674

    Integration of oral-systemic science into clinical care holds promise for improving patient outcomes and presenting opportunities for individuals in various health care professions to learn with, from, and about each other. The aim of this study was to examine whether an interprofessional continuing education program dedicated to oral-systemic health improved participants' attitudes toward interprofessional education and collaboration between dental and non-dental health care professionals and whether it influenced the physicians' practice of screening for debilitating oral diseases. The study took place in 2014 and used a mixed-methods approach, consisting of Readiness for Interprofessional Learning Scale (RIPLS) surveys conducted before, immediately after, and six months after the intervention, as well as surveys of self-reported practice behaviors and semi-structured interviews. A total of 231 health care professionals participated in the lectures and roundtable discussions. Of those, 134 responded to the pre-program survey (58% response rate), 110 responded to the post-program survey (48% response rate), and 58 responded to the survey six months after the program (25% response rate). The participants' median total RIPLS score at baseline was 76.5, which increased significantly immediately following the program (81.0) but returned to baseline six months later (76.5). Participants' RIPLS domain scores also increased significantly by profession from before to after the event, with effects returning to baseline after six months. Significantly more physicians reported screening for caries and periodontal disease after the intervention. An overall theme of "learning with, from, and about each other" was drawn from the interviews with 15 participants. The physicians took away a message of "just look in the mouth," while the dental professionals reported feeling valued as members of the health care team.

    2006-10-15

    There is a pressing need for a practical three-dimensional (3D) dosimetry system, convenient for clinical use, and with the accuracy and resolution to enable comprehensive verification of the complex dose distributions typical of modern radiation therapy. Here we introduce a dosimetry system that can achieve this challenge, consisting of a radiochromic dosimeter (PRESAGE trade mark sign ) and a commercial optical computed tomography (CT) scanning system (OCTOPUS trade mark sign ). PRESAGE trade mark sign is a transparent material with compelling properties for dosimetry, including insensitivity of the dose response to atmospheric exposure, a solid texture negating the need formore » an external container (reducing edge effects), and amenability to accurate optical CT scanning due to radiochromic optical contrast as opposed to light-scattering contrast. An evaluation of the performance and viability of the PRESAGE trade mark sign /OCTOPUS, combination for routine clinical 3D dosimetry is presented. The performance of the two components (scanner and dosimeter) was investigated separately prior to full system test. The optical CT scanner has a spatial resolution of {<=}1 mm, geometric accuracy within 1 mm, and high reconstruction linearity (with a R{sup 2} value of 0.9979 and a standard error of estimation of {approx}1%) relative to independent measurement. The overall performance of the PRESAGE trade mark sign /OCTOPUS system was evaluated with respect to a simple known 3D dose distribution, by comparison with GAFCHROMIC[reg] EBT film and the calculated dose from a commissioned planning system. The 'measured' dose distribution in a cylindrical PRESAGE trade mark sign dosimeter (16 cm diameter and 11 cm height) was determined by optical-CT, using a filtered backprojection reconstruction algorithm. A three-way Gamma map comparison (4% dose difference and 4 mm distance to agreement), between the PRESAGE trade mark sign , EBT and calculated dose distributions, showed

    The accurate estimation of the unsteady response (bandwidth) of pneumatic pressure probe systems (probe, line and transducer volume) is a common practical problem encountered in the design of aerodynamic experiments. Understanding the bandwidth of the probe system is necessary to capture unsteady flow features accurately. Where traversing probes are used, the desired traverse speed and spatial gradients in the flow dictate the minimum probe system bandwidth required to resolve the flow. Existing approaches for bandwidth estimation are either complex or inaccurate in implementation, so probes are often designed based on experience. Where probe system bandwidth is characterized, it is often done experimentally, requiring careful experimental set-up and analysis. There is a need for a relatively simple but accurate model for estimation of probe system bandwidth. A new model is presented for the accurate estimation of pressure probe bandwidth for simple probes commonly used in wind tunnel environments; experimental validation is provided. An additional, simple graphical method for air is included for convenience.

    Background Although cancer research has advanced at a rapid pace, a gap remains between what is known about how to improve cancer prevention and control (CPC) and what is implemented as best practices within health care systems and communities. The Cancer Prevention and Control Research Network (CPCRN), with more than 10 years of dissemination and implementation research experience, aims to accelerate the uptake and use of evidence-based CPC interventions. Methods The collective work of the CPCRN has facilitated the analysis and categorization of research and implementation efforts according to the Interactive Systems Framework for Dissemination and Implementation (ISF), providing a useful heuristic for bridging the gap between prevention research and practice. The ISF authors have called for examples of its application as input to help refine the model. Results We provide examples of how the collaborative activities supported by the CPCRN, using community-engaged processes, accelerated the synthesis and translation of evidence, built both general and innovation-specific capacity, and worked with delivery systems to advance cancer control research and practice. Conclusions The work of the CPCRN has provided real-world examples of the application of the ISF and demonstrated that synthesizing and translating evidence can increase the potential that evidence-based CPC programs will be used and that capacity building for both the support system and the delivery system is crucial for the successful implementation and maintenance of evidence-based cancer control. Impact Adoption and implementation of CPC can be enhanced by better understanding ISF systems and intervening to improve them. PMID:25155759

    Basing their rationale on multiple publications from Institute of Medicine (IOM), specifically Crossing the Quality Chasm, policy makers have focused on a broad range of issues, including assessment of the influence of medical practice organization structures on quality performance and development of quality measures. The 2006 Tax Relief and Health Care Act established the Physician Quality Reporting System (PQRS), to enable eligible professionals to report health care quality and health outcome information that cannot be obtained from standard Medicare claims. However, the Patient Protection and Affordable Care Act (ACA) of 2010 required the Centers for Medicare and Medicaid Services (CMS) to incorporate a combination of cost and quality into the payment systems for health care as a precursor to value-based payments. The final change to PQRS pending initiation after 2018, is based on the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) which has incorporated alternative payment models and merit-based payment systems. Recent publication of quality performance scores by CMS has been less than optimal. When voluntary participation began in July 2007, providers were paid a bonus for reporting quality measures from 2008 through 2014, ranging from 0.5% to 2% of the Medicare Part B allowed charges furnished during the reporting period. Starting in 2015, penalties started for nonparticipation. Eligible professionals and group practices that failed to satisfactorily report data on quality measures during 2014 are subject to a 2% reduction in Medicare fee-for-service amounts for services furnished by the eligible professional or group practice during 2016. The CMS proposed rule for 2016 physician payments contained a number of provisions with proposed updates to the PQRS and Physician Value-Based Payment Modifier among other changes. The proposed rule is the first release since MACRA repealed the sustainable growth rate formula. CMS proposed to continue many

    Objective Data collection and management by local health departments (LHDs) is a complex endeavor, complicated by system level and organizational factors. The purpose of this study was to describe the processes and use of information systems (IS) utilized for data collection, management, and sharing by LHD employees. Methods We interviewed a purposive sample of 12 staff working in the key public health practice areas of communicable disease control, immunizations, and vital records from three LHDs in different states. Our interview questions addressed job descriptions, daily activities, and the use and perceptions of both data and IS in support of their work. A content analytic approach was used to derive themes and categories common across programmatic areas. Results Local public health involves the use of mix of state-supplied and locally implemented IS supported by paper records. Additionally, each LHD in this study used at least one shadow system to maintain a duplicate set of information. Experiences with IS functionality and the extent to which it supported work varied by programmatic area, but inefficiencies, challenges in generating reports, limited data accessibility, and workarounds were commonly reported. Conclusions Current approaches to data management and sharing do not always support efficient public health practice or allow data to be used for organizational and community decision making. Many of the challenges to effective and efficient public health work were not solely technological. These findings suggest the need for interorganizational collaboration, increasing organizational capacity, workflow redesign, and end user training. PMID:24678380

    The purpose of this study was to examine practices used by a charter school system to hire and retain science teachers. The research design for this study was a qualitative case study. This single instrumental case study explored the issue within a bounded system. Purposeful sampling strategy was used to identify the participants who were interviewed individually. Findings of the case study supported that using online resources, advertising in the newspaper, attending job fairs, using alternative certification programs, attracting alumni, contacting the college of educations and hiring internationally helped the charter school system with hiring science teachers. Improving teacher salary scale, implementing teacher mentorship programs, reimbursing teachers for certification and master's programs, providing professional development and supporting teachers helped to retain science teachers. Therefore, this study contributes to determining strategies and techniques, selecting methods and programs, training administrators, and monitoring for successful hiring and retaining science teacher implementation.

    I will focus my comments on uncertainty and surprise in primary care practices. I am a medical anthropologist by training, and have been a full-time researcher in family medicine for close to twenty years. In this talk I want to look at primary care practices as complex systems, particularly taking the perspective of translating evidence into practice. I am going to discuss briefly the challenges we have in primary care, and in medicine in general, of translating new evidence into the everyday care of patients. To do this, I will look at two studies that we have conducted on family practices, then think about how practices can be best characterized as complex adaptive systems. Finally, I will focus on the implications of this portrayal for disseminating new knowledge into practice.

    This article applies the systems science of organizational cybernetics to the implementation of evidence-based practice (EBP) in the provision of social work services in a residential treatment center setting. It does so by systemically balancing EBP with practice-based evidence (PBE) with a focus on the organizational and information system infrastructures necessary to ensure successful implementation. This application is illustrated by discussing a residential treatment program that implemented evidence-based programming and evaluated the results; however, the systemic principles articulated can be applied to any human services organizational setting.

    The article considers the methodological and practical aspects of reclamation of landfills and dumps of municipal solid waste in a waste management system. The general tendencies of system development in the context of elements of the international concept of waste hierarchy are analyzed. Statistics of the formation and burial of domestic waste indicate a strategic non-alternative to the rejection of landfill technologies in favor of environmentally, energy efficient and economically expedient ways of utilization of municipal waste as a world trend. Practical approaches to the study of territories on which there are dumps and landfills are considered to justify the design solutions for reclamation.

    A fault current limiter (FCL) is extensively expected to suppress fault current, particularly required for trunk power systems heavily connected high-voltage transmission lines, such as 500kV class power system which constitutes the nucleus of the electric power system. By installing such FCL in the power system, the system interconnection is possible without the need to raise the capacity of the circuit breakers, and facilities can be configured for efficiency, among other benefits. For these reasons, fault current limiters based on various principles of operation have been developed both in Japan and abroad. In this paper, we have proposed a new type of FCL system, consisting of solid-state diodes, DC coil and bypass AC coil, and described the specification of distribution power system and 66kV model at the island power system and the superconducting cable power system. Also we have made a practical study of 66kV class, which is the testing items and the future subjects of the rectifier type FCL system.

  7. Healthcare improvement as planned system change or complex responsive processes? a longitudinal case study in general practice

    PubMed Central

    2013-01-01

    Background Interest in how to implement evidence-based practices into routine health care has never been greater. Primary care faces challenges in managing the increasing burden of chronic disease in an ageing population. Reliable prescriptions for translating knowledge into practice, however, remain elusive, despite intense research and publication activity. This study seeks to explore this dilemma in general practice by challenging the current way of thinking about healthcare improvement and asking what can be learned by looking at change through a complexity lens. Methods This paper reports the local level of an embedded case study of organisational change for better chronic illness care over more than a decade. We used interviews, document review and direct observation to explore how improved chronic illness care developed in one practice. This formed a critical case to compare, using pattern matching logic, to the common prescription for local implementation of best evidence and a rival explanation drawn from complexity sciences interpreted through modern sociology and psychology. Results The practice changed continuously over more than a decade to deliver better chronic illness care in line with research findings and policy initiatives – re-designing care processes, developing community linkages, supporting patient self-management, using guidelines and clinical information systems, and integrating nurses into the practice team. None of these improvements was designed and implemented according to an explicit plan in response to a documented gap in chronic disease care. The process that led to high quality chronic illness care exhibited clear complexity elements of co-evolution, non-linearity, self-organisation, emergence and edge of chaos dynamics in a network of agents and relationships where a stable yet evolving way of organizing emerged from local level communicative interaction, power relating and values based choices.

  11. Interactive effects among ecosystem services and management practices on crop production: pollination in coffee agroforestry systems.

    2013-05-21

    Crop productivity is improved by ecosystem services, including pollination, but this should be set in the context of trade-offs among multiple management practices. We investigated the impact of pollination services on coffee production, considering variation in fertilization, irrigation, shade cover, and environmental variables such as rainfall (which stimulates coffee flowering across all plantations), soil pH, and nitrogen availability. After accounting for management interventions, bee abundance improved coffee production (number of berries harvested). Some management interventions, such as irrigation, used once to trigger asynchronous flowering, dramatically increased bee abundance at coffee trees. Others, such as the extent and type of tree cover, revealed interacting effects on pollination and, ultimately, crop production. The effects of management interventions, notably irrigation and addition of lime, had, however, far more substantial positive effects on coffee production than tree cover. These results suggest that pollination services matter, but managing the asynchrony of flowering was a more effective tool for securing good pollination than maintaining high shade tree densities as pollinator habitat. Complex interactions across farm and landscape scales, including both management practices and environmental conditions, shape pollination outcomes. Effective production systems therefore require the integrated consideration of management practices in the context of the surrounding habitat structure. This paper points toward a more strategic use of ecosystem services in agricultural systems, where ecosystem services are shaped by the coupling of management interventions and environmental variables.

  12. Variability in Accreditation Council for Graduate Medical Education Resident Case Log System practices among orthopaedic surgery residents.

    2014-02-05

    The Accreditation Council for Graduate Medical Education (ACGME) Resident Case Log System is designed to be a reflection of residents' operative volume and an objective measure of their surgical experience. All operative procedures and manipulations in the operating room, Emergency Department, and outpatient clinic are to be logged into the Resident Case Log System. Discrepancies in the log volumes between residents and residency programs often prompt scrutiny. However, it remains unclear if such disparities truly represent differences in operative experiences or if they are reflections of inconsistent logging practices. The purpose of this study was to investigate individual recording practices among orthopaedic surgery residents prior to August 1, 2011. Orthopaedic surgery residents received a questionnaire on case log practices that was distributed through the Council of Orthopaedic Residency Directors list server. Respondents were asked to respond anonymously about recording practices in different clinical settings as well as types of cases routinely logged. Hypothetical scenarios of common orthopaedic procedures were presented to investigate the differences in the Current Procedural Terminology codes utilized. Two hundred and ninety-eight orthopaedic surgery residents completed the questionnaire; 37% were fifth-year residents, 22% were fourth-year residents, 18% were third-year residents, 15% were second-year residents, and 8% were first-year residents. Fifty-six percent of respondents reported routinely logging procedures performed in the Emergency Department or urgent care setting. Twenty-two percent of participants routinely logged procedures in the clinic or outpatient setting, 20% logged joint injections, and only 13% logged casts or splints applied in the office setting. There was substantial variability in the Current Procedural Terminology codes selected for the seven clinical scenarios. There has been a lack of standardization in case

    To determine the psychometric properties and validity of an OSCE to assess the competencies of Practice-Based Learning and Improvement (PBLI) and Systems-Based Practice (SBP) in graduate medical education. An eight-station OSCE was piloted at the end of a three-week Quality Improvement elective for nine preventive medicine and endocrinology fellows at Mayo Clinic. The stations assessed performance in quality measurement, root cause analysis, evidence-based medicine, insurance systems, team collaboration, prescription errors, Nolan's model, and negotiation. Fellows' performance in each of the stations was assessed by three faculty experts using checklists and a five-point global competency scale. A modified Angoff procedure was used to set standards. Evidence for the OSCE's validity, feasibility, and acceptability was gathered. Evidence for content and response process validity was judged as excellent by institutional content experts. Interrater reliability of scores ranged from 0.85 to 1 for most stations. Interstation correlation coefficients ranged from -0.62 to 0.99, reflecting case specificity. Implementation cost was approximately $255 per fellow. All faculty members agreed that the OSCE was realistic and capable of providing accurate assessments. The OSCE provides an opportunity to systematically sample the different subdomains of Quality Improvement. Furthermore, the OSCE provides an opportunity for the demonstration of skills rather than the testing of knowledge alone, thus making it a potentially powerful assessment tool for SBP and PBLI. The study OSCE was well suited to assess SBP and PBLI. The evidence gathered through this study lays the foundation for future validation work.

  14. A practical method to standardise and optimise the Philips DoseRight 2.0 CT automatic exposure control system.

    Given the increasing use of computed tomography (CT) in the UK over the last 30 years, it is essential to ensure that all imaging protocols are optimised to keep radiation doses as low as reasonably practicable, consistent with the intended clinical task. However, the complexity of modern CT equipment can make this task difficult to achieve in practice. Recent results of local patient dose audits have shown discrepancies between two Philips CT scanners that use the DoseRight 2.0 automatic exposure control (AEC) system in the 'automatic' mode of operation. The use of this system can result in drifting dose and image quality performance over time as it is designed to evolve based on operator technique. The purpose of this study was to develop a practical technique for configuring examination protocols on four CT scanners that use the DoseRight 2.0 AEC system in the 'manual' mode of operation. This method used a uniform phantom to generate reference images which form the basis for how the AEC system calculates exposure factors for any given patient. The results of this study have demonstrated excellent agreement in the configuration of the CT scanners in terms of average patient dose and image quality when using this technique. This work highlights the importance of CT protocol harmonisation in a modern Radiology department to ensure both consistent image quality and radiation dose. Following this study, the average radiation dose for a range of CT examinations has been reduced without any negative impact on clinical image quality.

  15. The impact of a private group practice of converting to an automated medical information system.

    As hardware and software developments make medical information systems increasingly available to physicians office practices and outpatients facilities, there is a need to focus on systems installation and conversion issues. In addition to the detailed step-by-step implementation plan, the overall impact of the new system should be anticipated. The purchasers should consider such issues as new information flow and user communication patterns between patient care and ancillary and support departments; restructuring of fundamental approaches to work allocation for either batch or real-time systems; and new emphasis on any departments vital to problem-spotting and solving. At California Primary Physicians (CPP), an awareness of these changes did not develop until well after the official "live" data had passed and the staff had been successfully using the system for several months. This paper explains how the above issues have emerged and the impact they have had on CPP, and provides a framework for anticipating such matters in any system installation.

    Existing diagnostic radiology peer-review systems do not address the specificities of interventional radiology (IR) practice. The purpose of this study was to assess the feasibility of a specifically developed interventional peer review method, IR Peer. Retrospective review of a prospectively encoded pilot database aimed at demonstrating the feasibility of IR Peer in a multiphysician practice was performed. This scoring system used morning peer review of selected IR cases from the previous day in the form of a five-item questionnaire and an ordinal answer scale that grades reviewers' agreement with imaging findings, procedural/technical management, early outcomes, and follow-up plan. Patient lists from IR Peer and morbidity and mortality (M&M) conferences were compared to evaluate the amount of overlap and capability of IR Peer to help detect adverse events (AEs). A total of 417 consecutive reviews of IR attending physician cases by peers were performed in 163 consecutive patients over 18 months, and 94% of cases were reviewed by two or three IR attending physicians. Each question was answered 99%-100% of the time. Answers showed disagreement in 10% of cases (2% by a single reviewer, 8% by several), most related to procedural technique. Overall AE incidence was 1.8%. IR Peer contributed 10.7% of cases to the M&M list. IR Peer is feasible, relevant, and easy to implement in a multiphysician IR practice. When used along with other quality-assurance processes, it might help in the detection of AEs for M&M; the latter will require further confirmatory research. © SIR, 2013.

    (1) To outline frameworks for neonatal physical therapy based on 3 theoretical models, (2) to describe emerging literature supporting neonatal physical therapy practice, and (3) to identify evidence-based practice recommendations. Three models are presented as a framework for neonatal practice: (1) dynamic systems theory including synactive theory and the theory of neuronal group selection, (2) the International Classification of Functioning, Disability and Health, and (3) family-centered care. Literature is summarized to support neonatal physical therapists in the areas of examination, developmental care, intervention, and parent education. Practice recommendations are offered with levels of evidence identified. Neonatal physical therapy practice has a theoretical and evidence-based structure, and evidence is emerging for selected clinical procedures. Continued research to expand the science of neonatal physical therapy is critical to elevate the evidence and support practice recommendations.

    2014-06-01

    This article draws on data collected during a 2-year project examining the deployment of a computerised decision support system. This computerised decision support system was designed to be used by non-clinical staff for dealing with calls to emergency (999) and urgent care (out-of-hours) services. One of the promises of computerised decisions support technologies is that they can 'hold' vast amounts of sophisticated clinical knowledge and combine it with decision algorithms to enable standardised decision-making by non-clinical (clerical) staff. This article draws on our ethnographic study of this computerised decision support system in use, and we use our analysis to question the 'automated' vision of decision-making in healthcare call-handling. We show that embodied and experiential (human) expertise remains central and highly salient in this work, and we propose that the deployment of the computerised decision support system creates something new, that this conjunction of computer and human creates a cyborg practice.

    There has been indisputable growth in adoption of electronic medical record (EMR) systems in the recent years. However, physicians' progress in using these systems has stagnated when measured with maturity scales. While this so-called ceiling effect has been observed and its consequences described in previous studies, there is a paucity of research on the elements that could explain such an outcome. We first suggest that in the context of EMR systems we are in presence of a "tiered ceiling effect" and then we show why such phenomenon occurs. We conducted in-depth case studies in three primary care medical practices in Canada where physicians had been using EMR systems for 3 years or more. A total of 37 semi-structured interviews were conducted with key informants: family physicians (about half of the interviews), nurses, secretaries, and administrative managers. Additional information was obtained through notes taken during observations of users interacting with their EMR systems and consultation of relevant documents at each site. We used abductive reasoning to infer explanations of the observed phenomenon by going back and forth between the case data and conceptual insights. Our analysis shows that a ceiling effect has taken place in the three clinics. We identified a set of conditions preventing the users from overcoming the ceiling. In adopting an EMR system, all three clinics essentially sought improved operational efficiency. This had an influence on the criteria used to assess the systems available on the market and eventually led to the adoption of a system that met the specified criteria without being optimal. Later, training sessions focussed on basic functionalities that minimally disturbed physicians' habits while helping their medical practices become more efficient. Satisfied with the outcome of their system use, physicians were likely to ignore more advanced EMR system functionalities. This was because their knowledge about EMR systems came almost

    A new dental remuneration system based on bands of activity has changed the reward system operating in dental practices and influenced practitioner behaviour in relation to the delegation of tasks to English dental therapists (DTs). Since dental practitioners operate as independent contractors they are free to innovate. A variety of models incorporating DTs in general practice teams exist, some of which may overcome the apparent delegation constraints embedded within this system of remuneration. To describe the way different practices are organised to take account of DTs in their teams and identify whether any of these models address delegation disincentives arising from the system of remuneration. A purposive sample of six dental practices was identified, comprising two small, two medium and two large dental practices, including a variety of models of practice organisation. Semi-structured interviews were carried out with principal dentists, associate dentists, DTs, practice managers and dental hygienists (35 participants in total). A thematic analysis was applied to interview transcripts. The six dental practices demonstrated six different models of practice organisation which could be grouped into 'practice payment' and 'dentist payment' models according to whether the salary costs of the DT were met by a central practice fund or from the income of individual dentists in the team. In both of the large practices only some of the dentists in the team referred work to the DT because of reimbursement issues. In two practices the system was perceived to be satisfactory to all parties, one of these being a single-handed practice with two DTs. Although the remuneration system contained some potential disincentives to DT delegation, some practices innovated in their organisations to overcome these issues.

  3. Aligning incentives in health care: physician practice and health system partnership.

    The key to successfully aligning hospitals and physicians is financial integration and joint incentives for academic, quality, and clinical productivity. Many physician practices and health systems are moving toward closer integration, but mainly through consolidation and employment strategies. We describe a fully integrated physician and hospital relationship including an overview of an aligned funds flow process that affords the department support for clinical services and teaching, research, and administrative activity. We also describe a physician compensation model that provides incentive not only for increased clinical performance, but also quality and academic objectives. The content of this article was acquired through our own experience in managing the Department of Orthopaedic Surgery at the University of Pennsylvania Health System including the health system's funds flow process. Based on input from both health system leaders and the faculty, the department's compensation plan was totally redesigned to create a line-of-sight plan that credits clinical performance and academic productivity. Our model is multifactorial and provides sustainable support for the department and a compensation plan that is competitive within the local market and nationally. The health system's funds flow process has enhanced alignment of the faculty and hospitals by providing compensation for nonclinical time and assists the department's growth strategies by providing funding for new faculty and gain-sharing of improved hospital margin. The implementation of the compensation plan increased productivity by 8% in its first year with no additional resources. Academic productivity in that same year was arguably at or above any other year in the department's history in terms of accepted publications, national presentations, and research grants awarded. A model of complete integration between an academic department and a health system is achievable through a systematic process of

    The present work demonstrates a valuable approach to developing quartz crystal microbalance (QCM) sensor units inexpensively for reliable determination of analytes. This QCM sensor unit is constructed by inkjet printing equipment utilizing background noise removal techniques. Inkjet printing equipment was chosen as an alternative to an injection pump in conventional flow-mode systems to facilitate the commercial applicability of these practical devices. The results demonstrate minimization of fluctuations from external influences, determination of antigen-antibody interactions in an inkjet deposition, and quantification of C-reactive protein in the range of 50–1000 ng(x000B7)mL−1. We thus demonstrate a marketable application of an inexpensive and easily available QCM sensor system. PMID:25360577

    Information technology (IT) support for remote collaboration of geographically distributed communities of practice (CoP) in health care must deal with a number of sociotechnical aspects of communication within the community. In the mid-1990s, participants of the Swedish Oral Medicine Network (SOMNet) began discussing patient cases in telephone conferences. The cases were distributed prior to the conferences using PowerPoint and email. For the technical support of online CoP, Semantic Web technologies can potentially fulfill needs of knowledge reuse, data exchange, and reasoning based on ontologies. However, more research is needed on the use of Semantic Web technologies in practice. The objectives of this research were to (1) study the communication of distributed health care professionals in oral medicine; (2) apply Semantic Web technologies to describe community data and oral medicine knowledge; (3) develop an online CoP, Swedish Oral Medicine Web (SOMWeb), centered on user-contributed case descriptions and meetings; and (4) evaluate SOMWeb and study how work practices change with IT support. Based on Java, and using the Web Ontology Language and Resource Description Framework for handling community data and oral medicine knowledge, SOMWeb was developed using a user-centered and iterative approach. For studying the work practices and evaluating the system, a mixed-method approach of interviews, observations, and a questionnaire was used. By May 2008, there were 90 registered users of SOMWeb, 93 cases had been added, and 18 meetings had utilized the system. The introduction of SOMWeb has improved the structure of meetings and their discussions, and a tenfold increase in the number of participants has been observed. Users submit cases to seek advice on diagnosis or treatment, to show an unusual case, or to create discussion. Identified barriers to submitting cases are lack of time, concern about whether the case is interesting enough, and showing gaps in one's own

    In 2004, NASA faced major knowledge sharing challenges due to geographically isolated field centers that inhibited personnel from sharing experiences and ideas. Mission failures and new directions for the agency demanded better collaborative tools. In addition, with the push to send astronauts back to the moon and to Mars, NASA recognized that systems engineering would have to improve across the agency. Of the ten field centers, seven had not built a spacecraft in over 30 years, and had lost systems engineering expertise. The Systems Engineering Community of Practice came together to capture the knowledge of its members using the suite of collaborative tools provided by the NASA Engineering Network (NEN.) The NEN provided a secure collaboration space for over 60 practitioners across the agency to assemble and review a NASA systems engineering handbook. Once the handbook was complete, they used the open community area to disseminate it. This case study explores both the technology and the social networking that made the community possible, describes technological approaches that facilitated rapid setup and low maintenance, provides best practices that other organizations could adopt, and discusses the vision for how this community will continue to collaborate across the field centers to benefit the agency as it continues exploring the solar system.

    Software safety assurance philosophy and practices at the NASA Ames are discussed. It is shown that, to be safe, software must be error-free. Software developments on two digital flight control systems and two ground facility systems are examined, including the overall system and software organization and function, the software-safety issues, and their resolution. The effectiveness of safety assurance methods is discussed, including conventional life-cycle practices, verification and validation testing, software safety analysis, and formal design methods. It is concluded (1) that a practical software safety technology does not yet exist, (2) that it is unlikely that a set of general-purpose analytical techniques can be developed for proving that software is safe, and (3) that successful software safety-assurance practices will have to take into account the detailed design processes employed and show that the software will execute correctly under all possible conditions.

    Dissemination of innovations is widely considered the sine qua non for system improvement. At least two dozen states are rolling-out evidence-based mental health practices targeted at children and families using trainings, consultations, webinars, and learning collaboratives to improve quality and outcomes. In New York State (NYS) a group of researchers, policy-makers, providers and family support specialists have worked in partnership since 2002 to redesign and evaluate the children’s mental health system. Five system strategies driven by empirically-based practices and organized within a state-supported infrastructure have been used in the child and family service system with over 2,000 providers: (a) business practices; (b) use of health information technologies in quality improvement; (c) specific clinical interventions targeted at common childhood disorders; (d) parent activation; and (e) quality indicator development. The NYS system has provided a laboratory for naturalistic experiments. We describe these initiatives, key findings and challenges, lessons learned for scaling, and implications for creating evidence-based implementation policies in state systems. PMID:24460518

    This paper validates the integration of a generic real-time wireless telemedicine system utilising Global System for Mobile Communications (GSM), BLUETOOTH protocol and General Packet Radio Service (GPRS) for cellular network in clinical practice. In the first experiment, the system was tested on 24 pacemaker patients at Aalborg Hospital (Denmark), in order to see if the pacemaker implant would be affected by the system. I the second experiment, the system was tested on 15 non risky arrhythmia heart patients, in order to evaluate and validate the system application in clinical practice, for patient monitoring. Electrocardiograms were selected as the continuously monitored parameter in the present study. The results showed that the system had no negative effects on the pacemaker implants. The experiment results showed, that in a realistic environment for the patients, the system had 96.1 % up-time, 3.2 (kbps) throughput, 10(-3) (packet/s) Packet Error Rate and 10(-3) (packet/s) Packet Lost Rate. During 24 hours test the network did not respond for 57 minutes, from which 83.1 % was in the range of 0-3 minutes, 15.4 % was in the range of 3-5 minutes, and only 0.7 % of the down-time was > or = 5 and < or = 6 minutes. By a subjective evaluation, it was demonstrated that the system is applicable and the patients as well as the healthcare personals were highly confident with the system. Moreover, the patients had high degree of mobility and freedom, employing the system. In conclusion, this generic telemedicine system showed a high reliability, quality and performance, and the design can provide a basic principle for real-time wireless remote monitoring systems used in clinical practice.

    This paper describes the goals of the American Society of Health-System Pharmacists' Pharmacy Practice Model Initiative (PPMI) and its recommendations for health-system pharmacy practice transformation to meet future patient care needs and elevate the role of pharmacists as patient care providers. PPMI envisions a future in which pharmacists have greater responsibility for medication-related outcomes and technicians assume greater responsibility for product-related activities. Although the PPMI recommendations have elevated the level of practice in many settings, they also potentially affect existing clinical pharmacists, in general, and clinical pharmacy specialists, in particular. Moreover, although more consistent patient care can be achieved with an expanded team of pharmacist providers, the role of clinical pharmacy specialists must not be diminished, especially in the care of complex patients and populations. Specialist practitioners with advanced training and credentials must be available to model and train pharmacists in generalist positions, residents, and students. Indeed, specialist practitioners are often the innovators and practice leaders. Negotiation between hospitals and pharmacy schools is needed to ensure a continuing role for academic clinical pharmacists and their contributions as educators and researchers. Lessons can be applied from disciplines such as nursing and medicine, which have developed new models of care involving effective collaboration between generalists and specialists. Several different pharmacy practice models have been described to meet the PPMI goals, based on available personnel and local goals. Studies measuring the impact of these new practice models are needed. © 2016 Pharmacotherapy Publications, Inc.

  15. An information-theoretic approach to assess practical identifiability of parametric dynamical systems.

    PubMed

    Pant, Sanjay; Lombardi, Damiano

    2015-10-01

    A new approach for assessing parameter identifiability of dynamical systems in a Bayesian setting is presented. The concept of Shannon entropy is employed to measure the inherent uncertainty in the parameters. The expected reduction in this uncertainty is seen as the amount of information one expects to gain about the parameters due to the availability of noisy measurements of the dynamical system. Such expected information gain is interpreted in terms of the variance of a hypothetical measurement device that can measure the parameters directly, and is related to practical identifiability of the parameters. If the individual parameters are unidentifiable, correlation between parameter combinations is assessed through conditional mutual information to determine which sets of parameters can be identified together. The information theoretic quantities of entropy and information are evaluated numerically through a combination of Monte Carlo and k-nearest neighbour methods in a non-parametric fashion. Unlike many methods to evaluate identifiability proposed in the literature, the proposed approach takes the measurement-noise into account and is not restricted to any particular noise-structure. Whilst computationally intensive for large dynamical systems, it is easily parallelisable and is non-intrusive as it does not necessitate re-writing of the numerical solvers of the dynamical system. The application of such an approach is presented for a variety of dynamical systems--ranging from systems governed by ordinary differential equations to partial differential equations--and, where possible, validated against results previously published in the literature.

  16. Interactive effects among ecosystem services and management practices on crop production: Pollination in coffee agroforestry systems

    2013-01-01

    Crop productivity is improved by ecosystem services, including pollination, but this should be set in the context of trade-offs among multiple management practices. We investigated the impact of pollination services on coffee production, considering variation in fertilization, irrigation, shade cover, and environmental variables such as rainfall (which stimulates coffee flowering across all plantations), soil pH, and nitrogen availability. After accounting for management interventions, bee abundance improved coffee production (number of berries harvested). Some management interventions, such as irrigation, used once to trigger asynchronous flowering, dramatically increased bee abundance at coffee trees. Others, such as the extent and type of tree cover, revealed interacting effects on pollination and, ultimately, crop production. The effects of management interventions, notably irrigation and addition of lime, had, however, far more substantial positive effects on coffee production than tree cover. These results suggest that pollination services matter, but managing the asynchrony of flowering was a more effective tool for securing good pollination than maintaining high shade tree densities as pollinator habitat. Complex interactions across farm and landscape scales, including both management practices and environmental conditions, shape pollination outcomes. Effective production systems therefore require the integrated consideration of management practices in the context of the surrounding habitat structure. This paper points toward a more strategic use of ecosystem services in agricultural systems, where ecosystem services are shaped by the coupling of management interventions and environmental variables.

    Beneficial effects of clinical practice guidelines (CPGs) have not yet reached expectations due to limited routine adoption. Electronic distribution and reminder systems have the potential to overcome implementation barriers. Existing electronic CPG repositories like the National Guideline Clearinghouse (NGC) provide individual access but lack standardized computer-readable interfaces necessary for automated guideline retrieval. The aim of this paper was to facilitate automated context-based selection and presentation of CPGs. Using attributes from the NGC classification scheme, an XML-based metadata repository was successfully implemented, providing document storage, classification and retrieval functionality. Semi-automated extraction of attributes was implemented for the import of XML guideline documents using XPath. A hospital information system interface was exemplarily implemented for diagnosis-based guideline invocation. Limitations of the implemented system are discussed and possible future work is outlined. Integration of standardized computer-readable search interfaces into existing CPG repositories is proposed. PMID:12463831

    Clinical pharmacy has a rich history of advancing practice through innovation. These innovations helped to mold clinical pharmacy into a patient-centered discipline recognized for its contributions to improving medication therapy outcomes. However, innovations in clinical pharmacy practice have now waned. In our view, the growth of academic–practice partnerships could reverse this trend and stimulate innovation among the next generation of pioneering clinical pharmacists. Although collaboration facilitates innovation,academic institutions and health care systems/organizations are not taking full advantage of this opportunity. The academic–practice partnership can be optimized by making both partners accountable for the desired outcomes of their collaboration, fostering symbiotic relationships that promote value-added clinical pharmacy services and emphasizing continuous quality improvement in the delivery of these services. Optimizing academic–practice collaboration on a broader scale requires both partners to adopt a culture that provides for dedicated time to pursue innovation, establishes mechanisms to incubate ideas, recognizes where motivation and vision align, and supports the purpose of the partnership. With appropriate leadership and support, a shift in current professional education and training practices, and a commitment to cultivate future innovators, the academic–practice partnership can develop new and innovative practice advancements that will improve patient outcomes.

  3. Promise and dismay: The state of strategic environmental assessment systems and practices in Canada

    Has strategic environmental assessment (SEA) finally reached a point of maturity in Canada? Or, is it still stumbling to find its place in the impact assessment family? Strategic environmental assessment has been ongoing in Canada for a number of years, both formally and informally, and under a variety of labels and institutional models. The result is a system of SEA that is diverse, founded on a range of principles and frameworks, and not well understood. This paper provides a critical review of Canadian SEA systems and practices. To accomplish this objective, a manageable and diverse set of past and recentmore » SEA and SEA-like frameworks and applications are described and critically analyzed based on a set of input, process, and output evaluation criteria. Results suggest considerable variability in SEA experience and value added. This is due in large part to the institutional and methodological pluralism of SEA, the boundaries of which are not well defined. Under the federal system, since the formalization of SEA, many applications have been disappointing in light of broader SEA good-practice principles and criteria. Indeed, some of the better examples of SEA have neither carried the SEA name tag nor occurred under formal SEA requirements. Further, many of the same challenges to project-based impact assessment also plague the development and value added of SEA. Of particular concern is the systematic separation of SEA from downstream decision inputs and assessment activities. As Canada commences review of its federal SEA Directive in preparation for the next generation of SEA, this paper reflects on what it has achieved in the prior.« less

    In 2011, we made predictions on the basis of data from the National Practice Benchmark (NPB) reports from 2005 through 2010. With the new 2011 data in hand, we have revised last year's predictions and projected for the next 3 years. In addition, we make some new predictions that will be tracked in future benchmarking surveys. We also outline a conceptual framework for contemplating these data based on an ecological model of the oncology delivery system. The 2011 NPB data are consistent with last year's prediction of a decrease in the operating margins necessary to sustain a community oncology practice. With the new data in, we now predict these reductions to occur more slowly than previously forecast. We note an ease to the squeeze observed in last year's trend analysis, which will allow more time for practices to adapt their business models for survival and offer the best of these practices an opportunity to invest earnings into operations to prepare for the inevitable shift away from historic payment methodology for clinical service. This year, survey respondents reported changes in business structure, first measured in the 2010 data, indicating an increase in the percentage of respondents who believe that change is coming soon, but the majority still have confidence in the viability of their existing business structure. Although oncology practices are in for a bumpy ride, things are looking less dire this year for practices participating in our survey.

    Background Computerized chronic disease management systems (CDMSs), when aligned with clinical practice guidelines, have the potential to effectively impact diabetes care. Objective The objective was to measure the difference between optimal diabetes care and actual diabetes care before and after the introduction of a computerized CDMS. Methods This 1-year, prospective, observational, pre/post study evaluated the use of a CDMS with a diabetes patient registry and tracker in family practices using patient enrolment models. Aggregate practice-level data from all rostered diabetes patients were analyzed. The primary outcome measure was the change in proportion of patients with up-to-date “ABC” monitoring frequency (i.e., hemoglobin A1c, blood pressure, and cholesterol). Changes in the frequency of other practice care and treatment elements (e.g., retinopathy screening) were also determined. Usability and satisfaction with the CDMS were measured. Results Nine sites, 38 health care providers, and 2,320 diabetes patients were included. The proportion of patients with up-to-date ABC (12%), hemoglobin A1c (45%), and cholesterol (38%) monitoring did not change over the duration of the study. The proportion of patients with up-to-date blood pressure monitoring improved, from 16% to 20%. Data on foot examinations, retinopathy screening, use of angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, and documentation of self-management goals were not available or not up to date at baseline for 98% of patients. By the end of the study, attitudes of health care providers were more negative on the Training, Usefulness, Daily Practice, and Support from the Service Provider domains of the CDMS, but more positive on the Learning, Using, Practice Planning, CDMS, and Satisfaction domains. Limitations Few practitioners used the CDMS, so it was difficult to draw conclusions about its efficacy. Simply giving health care providers a potentially useful technology

    Competent examination of the pediatric musculoskeletal (MSK) system is a vital component of clinical assessment of children with MSK presentations. The aim was to develop a regional MSK examination for school-age children that is age appropriate and reflects clinical practice. Qualitative and quantitative analyses involving video observation of clinical examination technique, systematic review, and expert consensus were employed to reveal descriptions, frequencies, and variations in technique for joint regions in various clinical scenarios. Systematic review and data from clinical observation were combined with feedback from a group of pediatric MSK experts through a web-based survey. All results were collated and discussed by consensus development groups to derive the pediatric Regional Examination of the Musculoskeletal System (pREMS). A total of 48 pediatric MSK expert clinicians were involved to derive pREMS. Systematic review revealed a paucity of evidence about regional pediatric MSK examination. Video observations of MSK examinations (a total of 2,901 maneuvers) performed by pediatric MSK experts (n = 11 doctors and 8 therapists) of 89 school-age children attending outpatient clinics in 7 UK pediatric rheumatology centers were followed by semistructured interviews with 14 of 19 clinicians. Video observation showed variation in examination techniques, most frequently at the hip and knee in the context of mechanical and inflammatory clinical scenarios. pREMS is the first practice- and consensus-based regional pediatric MSK examination for school-age children. The structured approach is an important step toward improved pediatric MSK clinical skills relevant to clinical training. Copyright © 2011 by the American College of Rheumatology.

    Today medicine is facing a "knowledge crisis" in that explosively expanding medical knowledge encounters limited abilities to disseminate new practices [1]. Clinical practice guidelines (CPGs) are intended to promote high standards of care in specific areas of medicine by summarizing best clinical practice based on careful reviews of current research. However, doctors are often short of time to study these documents and check their updates, have little motivation for strict adherence to them. A systematic review of 11 studies reporting on 29 recommendations has found that median adherence to all recommendations was 34%, suggesting that potential benefits for patients from health research may be lost [2].Clinical decision support systems (CDSS) can serve as a knowledge translation tool, mediator between clinical guidelines and physicians by providing the right information to the right person at the right time. To evaluate the effectiveness of implementation of international and national CPGs for venous thromboembolism (VTE) prevention with the help of CDSS in a general hospital. A multifunctional CDSS based on national and international guidelines on the VTE prevention was developed and implemented in the Medical Center of the Bank of Russia (MC). The system has the following functionalities: 1) it supports the decision on the VTE prevention based on individual risk assessment of thrombosis (scales of Caprini, Rogers and Khorana, Padua Prediction Score, additional risk factors) and bleeding (IMPROVE scale for non-surgical patients, major bleeding scale for surgical patients and major orthopedic surgeries, hemorrhagic complications risk in cancer patients); 2) generates the summary containing the grade of recommendations and the level of evidence, personalized recommendations on regimen and duration of preventive antithrombotic therapy, dose correction according to creatinine clearance; 3) provides an audit form for and statistical analysis of VTE cases; 3

  10. A new method for designing dual foil electron beam forming systems. II. Feasibility of practical implementation of the method

    2016-05-01

    In Part I of this work a new method for designing dual foil electron beam forming systems was introduced. In this method, an optimal configuration of the dual foil system is found by means of a systematic, automatized scan of system performance in function of its parameters. At each point of the scan, Monte Carlo method is used to calculate the off-axis dose profile in water taking into account detailed and complete geometry of the system. The new method, while being computationally intensive, minimizes the involvement of the designer. In this Part II paper, feasibility of practical implementation of the new method is demonstrated. For this, a prototype software tools were developed and applied to solve a real life design problem. It is demonstrated that system optimization can be completed within few hours time using rather moderate computing resources. It is also demonstrated that, perhaps for the first time, the designer can gain deep insight into system behavior, such that the construction can be simultaneously optimized in respect to a number of functional characteristics besides the flatness of the off-axis dose profile. In the presented example, the system is optimized in respect to both, flatness of the off-axis dose profile and the beam transmission. A number of practical issues related to application of the new method as well as its possible extensions are discussed.

    OBJECTIVE To identify factors associated with oral hygiene practices in adults with systemic sclerosis (SSc) METHODS In this cross-sectional study, 178 dentate adults with SSc received an oral examination which included measurement of oral aperture, assessment of manual dexterity to perform oral hygiene, as well as completion of the Center of Epidemiological Studies Depression (CES-D) Scale, and an oral health-related questionnaire. RESULTS Multivariable logistic regression modeling showed male, minority and high CES-D scores (i.e., clinically significant symptoms of depression) were associated with less likelihood of participants brushing teeth at least twice daily, but the presence of self-reported dry mouth symptoms increased the likelihood of toothbrushing. Having a dental visit in the past 12 months, and use of an adapted flossing or interdental cleaning device were significantly associated with daily dental flossing; however, having difficulty flossing teeth reduced the likelihood of daily flossing. CONCLUSIONS Overall, demographic variables were strongly associated with toothbrushing frequency, whereas, flossing self-efficacy and barriers were strongly associated with dental flossing frequency in adults with SSc. The results suggest that dental health professionals should take mental health into consideration when educating patients with SSc to improve their oral hygiene, and consider making referrals for patients exhibiting suspected clinically significant depressive symptoms to mental health professionals for further evaluation and treatment. In addition, an appropriate adapted flossing or interdental cleaning device should be recommended to increase dental flossing practices in this patient population. PMID:24128049

    Because of social background, such as repeated large earthquakes and cheating in design and construction, structural health monitoring (SHM) systems are getting strong attention. The SHM systems are in a practical phase. An SHM system consisting of small number of sensors has been introduced to 6 tall buildings in Shinjuku area. Including them, there are 2 major issues in the SHM systems consisting of small number of sensors. First, optimal system number of sensors and the location are not well-defined. In the practice, system placement is determined based on rough prediction and experience. Second, there are some uncertainties in estimation results by the SHM systems. Thus, the purpose of this research is to provide useful information for increasing reliability of SHM system and to improve estimation results based on uncertainty analysis of the SHM systems. The important damage index used here is the inter-story drift angle. The uncertainty considered here are number of sensors, earthquake motion characteristics, noise in data, error between numerical model and real building, nonlinearity of parameter. Then I have analyzed influence of each factor to estimation accuracy. The analysis conducted here will help to decide sensor system design considering valance of cost and accuracy. Because of constraint on the number of sensors, estimation results by the SHM system has tendency to provide smaller values. To overcome this problem, a compensation algorithm was discussed and presented. The usefulness of this compensation method was demonstrated for 40 story S and RC building models with nonlinear response.

    Subsurface drainage systems are widely used throughout the upper Midwest corn-belt. While the use of these drainage systems has greatly increased crop production, they have also increased nitrate-nitrogen export to downstream waterbodies. As a result, there is a need to evaluate and implement management practices that have potential to reduce nitrate-nitrogen loss. A twenty year study in Iowa has shown that major factors in nitrate-nitrogen loss are land use and hydrology. Studies from north-central Iowa have also indicated that nitrogen application rate and to a lesser degree timing of nitrogen application important factors for nitrate-nitrogen loss. A four-year (2007-2010) drainage management study in southeast Iowa indicates that shallow and controlled drainage systems have potential to decrease subsurface drainage and thereby reduce nitrate-N loss from drain water but the level of implementation of controlled drainage may be limited by topography. Cropping practices through cover crops or perennial biomass crops have also been documented to have potential to reduce downstream nitrate-nitrogen export but the level of implementation may be limited by management and economic considerations. To achieve reduction goals for protection of local and regional water quality will require a combination of these practices at the landscape scale.

    Organic production and consumption provide a delineated food system that can be explored for its potential contribution to sustainable diets. While organic agriculture improves the sustainability performance on the production side, critical reflections are made on how organic consumption patterns, understood as the practice of people consuming significant amounts of organic produce, may also be taken as an example for sustainable food consumption. The consumption patterns of regular organic consumers seem to be close to the sustainable diet concept of FAO. Certain organic-related measures might therefore be useful in the sustainability assessment of diets, e.g., organic production and organic consumption. Since diets play a central role in shaping food systems and food systems shape diets, the role of organic consumption emerges as an essential topic to be addressed. This role may be based on four important organic achievements: organic agriculture and food production has a definition, well-established principles, public standards, and useful metrics. By 2015, data for organic production and consumption are recorded annually from more than 160 countries, and regulations are in force in more than 80 countries or regions. The organic food system puts the land (agri-cultura) back into the diet; it is the land from which the diet in toto is shaped. Therefore, the organic food system provides essential components of a sustainable diet. PMID:26176912

    In a practical continuous-variable quantum-key distribution (CVQKD), the fluctuations of the local oscillator (LO) not only make the normalization of Bob's measurement outcomes difficult, but also can change the signal-to-noise ratio (SNR) of an imperfect balanced homodyne detector (BHD), which may lead the security of a practical system of CVQKD to be compromised severely. In this paper, we propose that the LO intensity can be manipulated by the legitimate parties, i.e., being tuned and stabilized to a required constant value, to eliminate the impact of LO fluctuations and defeat Eve's potential attack on the LO. Moreover, we show that the secret key rate can be increased over a noisy channel, especially the channels of metropolitan QKD networks, by tuning the intensity of LO and thus the SNR of a practical BHD to an optimal value, and we find that, counterintuitively, the requirement on BHD (i.e., high detection efficiency and low electronic noise) can also be reduced in this case. To realize this manipulation, we give a schematic setup which, thus, can be used to enhance the security of a practical CVQKD system.

    Guideline-based clinical decision support systems (CDSSs) can be effective in increasing physician compliance with recommendations. However, the ever growing pace at which medical knowledge is produced requires that clinical practice guidelines (CPGs) be updated regularly. It is therefore mandatory that CDSSs be revised accordingly. The French Association for Urology publishes CPGs on bladder cancer management every 2 years. We studied the impact of the 2004 revision of these guidelines, with respect to the 2002 version with a CDSS, UroDoc. We proposed a typology of knowledge base modifications resulting from the update of CPGs making the difference between practice, clinical conditions and recommendations refinement as opposed to new practice and new recommendations. The number of formalized recommendations increased from 577 in 2002 to 1,081 in 2004. We evaluated the two versions of UroDoc on a randomized sample of patient records. A single new practice that modifies a decision taken in 49% of all recorded decisions leads to a fall from 67% to 46% of the compliance rate of decisions.

    Applying the principles of harm reduction within the context of incarcerated populations raises a number of challenges. Although some access to harm reduction strategies has been promoted in general society, a divide between what is available and what is advocated continues to exist within the prison system. This paper explores the perceptions and lived experiences of a sample of nationally incarcerated women in Canada regarding their perceptions and experiences in accessing HIV and Hepatitis C prevention, care, treatment and support. In-depth interviews were conducted with 156 women in Canadian national prisons. Q.S.R. Nudist was used to assist with data management. A constant comparison method was used to derive categories, patterns, and themes. Emergent themes highlighted a gap between access to harm reduction in policy and in practice. Despite the implementation of some harm reduction techniques, women in Canadian prisons reported variable access to both education and methods of reducing HIV/HCV transmission. Concerns were also raised about pre-and post-test counseling for HIV/HCV testing. Best practices are suggested for implementing harm reduction strategies within prisons for women in Canada.

    Assessment of spinal posture during physiotherapy practice is routine, yet few objective measures exist to this end. The Middlesbrough Integrated Digital Assessment System (MIDAS) is a low cost portable system able to record 3D information on posture. The purpose of this study was to assess both the intra-rater and inter-rater reliability of the MIDAS system. Twenty-five healthy subjects were recruited. A repeated measures design was used to record fifteen pre-palpated landmarks on the back of each subject. To limit the sources of variability, the principal researcher palpated the landmarks for each subject. Each of three raters took two measurements on each subject in a standardized upright posture. X (medio-lateral), Y (antero-posterior) and Z (height) landmark positions were recorded via a computer interface. Both intra-rater agreement (mean ICCs - rater 1 r=0.970, rater 2 r=0.965 and rater 3 r=0.965, p< 0.001) and inter-rater agreement (mean ICCs r=0.967, p< 0.001) was very high between repeated measures and between markers. Error values for the z-axis (height) were the lowest. The MIDAS demonstrated both high inter-rater and intra-rater reliability and provides an objective method for the assessment of posture in physiotherapy practice.

  3. Social Values, Regulatory Tensions and Professional Practices with Underprivileged Populations: The Case of Quebec's Oral Healthcare System

    PubMed Central

    Bedos, Christophe

    2011-01-01

    Objective: Dentists may experience frustration in their practice with people living on welfare, often perceiving them in a negative light. The difficulties encountered are detrimental to the patient—professional relationship and contribute to compromising access to care for this underprivileged population. In order to fully understand patient—professional interactions, we must consider the macroscopic contexts in which they occur. This paper examines the systemic influences of these interpersonal relationships to deepen our understanding of an important access-to-care determinant for people living on welfare. Methods: Two frameworks are applied to the analysis of Quebec's oral healthcare system: the social values framework and the regulatory logics framework. Results: Our assessment leads us to posit two phenomena: (1) certain negative stereotypes regarding patients living on welfare allow dentists to manage the inevitable regulatory conflicts (i.e., economic vs. professional) involved in their practice and (2) the behaviours of people living on welfare are frequently judged according to the social values embodied in the organization of Quebec's oral healthcare system, delivery and financing. Conclusion: Quebec's oral healthcare system fails to provide effective access to care for individuals living in poverty, and the government must significantly augment its involvement in this healthcare sector. Dentists should also understand the impact that systemic influences have on their rapport with people living on welfare. We argue that new orientations for the field of dental professional education should be considered.

    Evidence suggests that many small- and medium-scale Electronic Health Record (EHR) implementations encounter problems, these often stemming from users' difficulties in accommodating the new technology into their work practices. There is the possibility that these challenges may be exacerbated in the context of the larger-scale, more standardised, implementation strategies now being pursued as part of major national modernisation initiatives. We sought to understand how England's centrally procured and delivered EHR software was integrated within the work practices of users in selected secondary and specialist care settings. We conducted a qualitative longitudinal case study-based investigation drawing on sociotechnical theory in three purposefully selected sites implementing early functionality of a nationally procured EHR system. The complete dataset comprised semi-structured interview data from a total of 66 different participants, 38.5 hours of non-participant observation of use of the software in context, accompanying researcher field notes, and hospital documents (including project initiation and lessons learnt reports). Transcribed data were analysed thematically using a combination of deductive and inductive approaches, and drawing on NVivo8 software to facilitate coding. The nationally led "top-down" implementation and the associated focus on interoperability limited the opportunity to customise software to local needs. Lack of system usability led users to employ a range of workarounds unanticipated by management to compensate for the perceived shortcomings of the system. These had a number of knock-on effects relating to the nature of collaborative work, patterns of communication, the timeliness and availability of records (including paper) and the ability for hospital management to monitor organisational performance. This work has highlighted the importance of addressing potentially adverse unintended consequences of workarounds associated with the

    Despite its remarkable barrier function, the skin remains an attractive site for systemic drug delivery given its easy accessibility, large surface area and the possibility to bypass the gastrointestinal tract and the liver and so modify drug absorption kinetics. The pioneering work of Scheuplein, Higuchi and others in the 1960s helped to explain the processes involved in passive percutaneous absorption and led to the development of mathematical models to describe transdermal drug delivery. The intervening years have seen these theories turned to practice and a significant number of transdermal systems are now available including some that employ active drug delivery. This review briefly discusses the evolution of transdermal therapeutic systems over the years and the potential of newer transdermal technologies to deliver hydrophilic drugs and macromolecules through the skin. © 2013 S.

    This study examines the capability of the Clinical Care Classification (CCC) system to represent nursing record data in a medical center in Taiwan. Nursing care records were analyzed using the process of knowledge discovery in data sets. The study data set included all the nursing care plan records from December 1998 to October 2008, totaling 2,060,214 care plan documentation entries. Results show that 75.42% of the documented diagnosis terms could be mapped using the CCC system. A total of 21 established nursing diagnoses were recommended to be added into the CCC system. Results show that one-third of the assessment and care tasks were provided by nursing professionals. This study shows that the CCC system is useful for identifying patterns in nursing practices and can be used to construct a nursing database in the acute setting. PMID:24199066

    Prevalence of new diseases, medical science promotion and increase of referring to health care centers, provide a good situation for medical errors growth. Errors can involve medicines, surgery, diagnosis, equipment, or lab reports. Medical errors can occur anywhere in the health care system: In hospitals, clinics, surgery centers, doctors' offices, nursing homes, pharmacies, and patients' homes. According to the Institute of Medicine (IOM), 98,000 people die every year from preventable medical errors. In 2010 from all referred medical error records to Iran Legal Medicine Organization, 46/5% physician and medical team members were known as delinquent. One of new technologies that can reduce medical errors is clinical decision support systems (CDSSs). This study was unsystematic-review study. The literature was searched on evaluate the "ability of clinical decision support systems to improve clinical practice" with the help of library, books, conference proceedings, data bank, and also searches engines available at Google, Google scholar. For our searches, we employed the following keywords and their combinations: medical error, clinical decision support systems, Computer-Based Clinical Decision Support Systems, information technology, information system, health care quality, computer systems in the searching areas of title, keywords, abstract, and full text. In this study, more than 100 articles and reports were collected and 38 of them were selected based on their relevancy. The CDSSs are computer programs, designed for help to health care careers. These systems as a knowledge-based tool could help health care manager in analyze evaluation, improvement and selection of effective solutions in clinical decisions. Therefore, it has a main role in medical errors reduction. The aim of this study was to express ability of the CDSSs to improve

    Aim: Every year, millions of people around the world suffer from different infectious diseases, considerable part of which are hospital-acquired infections. WHO considers hand hygiene as a priority measure aimed to reduce the level of infection. We evaluated various aspects related to the situational behavior and prioritization regarding hand hygiene measures among the healthcare workers of Ukraine. Method: Identification of system mistakes in hand hygiene was carried out first of all by direct and indirect observation of the activities of medical and pharmaceutical personnel in their everyday practice as well as during their participation in trainings on routine hand hygiene. Questionnaires also were used to estimate the level of hand hygiene compliance of participants of the study. During this period 112 training courses, 315 master-classes and presentations on proper hand hygiene were realized. The target audience included health care workers of medical centers, clinics, maternity hospitals, health care organizations and staff of pharmacies and pharmaceutical manufacturing enterprises in all regions of Ukraine. 638 respondents took part in anonymous survey on hand hygiene practice. Results: The most common mistakes were to regard hand washing and hand disinfection equally, to wash hands before doing a hand disinfection, to neglect the five moments for hand hygiene and to ignore hand hygiene before and after wearing protective gloves. Practitioners, medical attendants, pharmacy and pharmaceutical industry workers highlighted the need for practical and understandable instructions of various hand hygiene procedures, including the clarification of the possible technical mistakes. This became a ground for us to create individual master classes on hand hygiene for each cluster of healthcare workers. Conclusions: Changing hand hygiene behavior and attitude is possible by beginning to observe clinical practice and by involving healthcare workers in teaching and training

    The models of practice that general practice registrars (GPRs) envisage undertaking will affect workforce supply. The aim of this research was to determine practice intentions of current GPRs in a regional general practice training program (Coast City Country General Practice Training). Questionnaires were circulated to 220 GPRs undertaking general practice placements to determine characteristics of ideal practice models and intentions for future practice. Responses were received for 99 participants (45%). Current GPRs intend to work an average of less than eight half-day sessions/week, with male participants intending to work more hours (t(91)=3.528, P=0.001). More than one-third of this regional cohort intends to practice in metropolitan centres. Proximity to family and friends was the most important factor influencing the choice of practice location. Men ranked remuneration for work as more important (t (88)=-4.280, P<0.001) and women ranked the ability to work part-time higher (t(94)=3.697, P<0.001). Fee-for-service payment alone, or in combination with capitation, was the preferred payment system. Only 22% of Australian medical graduates intend to own their own practice compared with 52% of international medical graduates (χ 2 (1)=8.498, P=0.004). Future general practitioners (GPs) intend to work fewer hours than current GPs. Assumptions about lifestyle factors, practice models and possible professional roles should be carefully evaluated when developing strategies to recruit GPs and GPRs into rural practice.

    Rigorous practices for safe dispensing of investigational drugs are not standardized. This investigation sought to identify error-prevention processes utilized in the provision of investigational drug services (IDS) and to characterize pharmacists' perceptions about safety risks posed by investigational drugs. An electronic questionnaire was distributed to an audience of IDS pharmacists within the Veteran Affairs Health System. Multiple facets were examined including demographics, perceptions of medication safety, and standard processes used to support investigational drug protocols. Twenty-one respondents (32.8% response rate) from the Northeast, Midwest, South, West, and Non-contiguous United States participated. The mean number of pharmacist full-time equivalents (FTEs) dedicated to the IDS was 0.77 per site with 0.2 technician FTEs. The mean number of active protocols was 22. Seventeen respondents (81%) indicated some level of concern for safety risks. Concerns related to the packaging of medications were expressed, most notably lack of product differentiation, expiration dating, barcodes, and choice of font size or color. Regarding medication safety practices, the majority of sites had specific procedures in place for storing and securing drug supply, temperature monitoring, and prescription labeling. Repackaging bulk items and proactive error-identification strategies were less common. Sixty-seven percent of respondents reported that an independent double check was not routinely performed. Medication safety concerns exist among pharmacists in an investigational drug service; however, a variety of measures have been employed to improve medication safety practices. Best practices for the safe dispensing of investigational medications should be developed in order to standardize these error-prevention strategies.

    The poor translation of evidence into practice is a well-known problem. Hopes are high that information technology can help make evidence-based practice feasible for mere mortal physicians. In this paper, we draw upon the methods and perspectives of clinical practice, medical informatics, and health services research to analyze the gap between evidence and action, and to argue that computing systems for bridging this gap should incorporate both informatics and health services research expertise. We discuss 2 illustrative systems—trial banks and a web-based system to develop and disseminate evidence-based guidelines (alchemist)— and conclude with a research and training agenda. PMID:11972727

    For most healthcare information systems, passwords are the first line of defense in keeping patient and administrative records private and secure. However, this defense is only as strong as the passwords employees chose to use. A weak or easily guessed password is like an open door to the medical records room, allowing unauthorized access to sensitive information. In this paper, we present the results of a study of actual healthcare workers' password practices. In general, the vast majority of these passwords have significant security problems on several dimensions. Implications for healthcare professionals are discussed.

    Clinical practice is the primary focus of advanced practice nursing (APN) roles. However, with unprecedented needs for health care reform and quality improvement (QI), health care administrators are seeking new ways to utilize all dimensions of APN expertise, especially related to research and evidence-based practice. International studies reveal research as the most underdeveloped and underutilized aspect of these roles. To improve patient care by strengthening the capacity of advanced practice nurses to integrate research and evidence-based practice activities into their day-to-day practice. An academic-practice partnership was created among hospital-based advanced practice nurses, nurse administrators, and APN researchers to create an innovative approach to educate and mentor advanced practice nurses in conducting point-of-care research, QI, or evidence-based practice projects to improve patient, provider, and/or system outcomes. A practice-based research course was delivered to 2 cohorts of advanced practice nurses using a range of teaching strategies including 1-to-1 academic mentorship. All participants completed self-report surveys before and after course delivery. Through participation in this initiative, advanced practice nurses enhanced their knowledge, skills, and confidence in the design, implementation, and/or evaluation of research, QI, and evidence-based practice activities. Evaluation of this initiative provides evidence of the acceptability and feasibility of academic-practice partnerships to educate and mentor point-of-care providers on how to lead, implement, and integrate research, QI and evidence-based activities into their practices. © 2016 John Wiley & Sons, Ltd.

  17. TrackCC: A Practical Wireless Indoor Localization System Based on Less-Expensive Chips

    Li, Xiaolong; Zheng, Yan; Cai, Jun; Yi, Yunfei

    2017-01-01

    This paper aims at proposing a new wireless indoor localization system (ILS), called TrackCC, based on a commercial type of low-power system-on-chip (SoC), nRF24LE1. This type of chip has only l output power levels and acute fluctuation for a received minimum power level in operation, which give rise to many practical challenges for designing localization algorithms. In order to address these challenges, we exploit the Markov theory to construct a (l+1)×(l+1) -sized state transition matrix to remove the fluctuation, and then propose a priority-based pattern matching algorithm to search for the most similar match in the signal map to estimate the real position of unknown nodes. The experimental results show that, compared to two existing wireless ILSs, LANDMARC and SAIL, which have meter level positioning accuracy, the proposed TrackCC can achieve the decimeter level accuracy on average in both line-of-sight (LOS) and non-line-of-sight (NLOS) senarios.

    1991-01-01

    For practical industrial applications, the development of trainable robots is an important and immediate objective. Therefore, the developing of flexible intelligence directly applicable to training is emphasized. It is generally agreed upon by the AI community that the fusion of expert systems, neural networks, and conventionally programmed modules (e.g., a trajectory generator) is promising in the quest for autonomous robotic intelligence. Autonomous robot development is hindered by integration and architectural problems. Some obstacles towards the construction of more general robot control systems are as follows: (1) Growth problem; (2) Software generation; (3) Interaction with environment; (4) Reliability; and (5) Resource limitation. Neural networks can be successfully applied to some of these problems. However, current implementations of neural networks are hampered by the resource limitation problem and must be trained extensively to produce computationally accurate output. A generalization of conventional neural nets is proposed, and an architecture is offered in an attempt to address the above problems.

    Developing electronic health record information systems is an international trend for promoting the integration of health information and enhancing the quality of medical services. Patient education is a frequent intervention in nursing care, and recording the amount and quality of patient education have become essential in the nursing record. The aims of this study are (1): to develop a high-quality Patient Education Assessment and Description Record System (PEADRS) in the electronic medical record (2); to examine the effectiveness of the PEADRS on documentation and nurses' satisfaction (3); to facilitate communication and cooperation between professionals. A quasi-experimental design and random sampling will be used. The participants are nurses who are involved in patient education by using traditional record or the PEADRS at a medical centre. A prospective longitudinal nested cohort study will be conducted to compare the effectiveness of the PEADRS, including (1): the length of nursing documentation (2); satisfaction with using the PEADRS; and (3) the benefit to professional cooperation. Patient privacy will be protected according to Electronic Medical Record Management Practices of the hospital. This study develops a patient education digital record system, which would profit the quality of clinical practice in health education. The results will be published in peer-reviewed journals and will be presented at scientific conferences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  1. A hydro-sedimentary modeling system for flash flood propagation and hazard estimation under different agricultural practices

    NASA Astrophysics Data System (ADS)

    Kourgialas, N. N.; Karatzas, G. P.

    2014-03-01

    A modeling system for the estimation of flash flood flow velocity and sediment transport is developed in this study. The system comprises three components: (a) a modeling framework based on the hydrological model HSPF, (b) the hydrodynamic module of the hydraulic model MIKE 11 (quasi-2-D), and (c) the advection-dispersion module of MIKE 11 as a sediment transport model. An important parameter in hydraulic modeling is the Manning's coefficient, an indicator of the channel resistance which is directly dependent on riparian vegetation changes. Riparian vegetation's effect on flood propagation parameters such as water depth (inundation), discharge, flow velocity, and sediment transport load is investigated in this study. Based on the obtained results, when the weed-cutting percentage is increased, the flood wave depth decreases while flow discharge, velocity and sediment transport load increase. The proposed modeling system is used to evaluate and illustrate the flood hazard for different riparian vegetation cutting scenarios. For the estimation of flood hazard, a combination of the flood propagation characteristics of water depth, flow velocity and sediment load was used. Next, a well-balanced selection of the most appropriate agricultural cutting practices of riparian vegetation was performed. Ultimately, the model results obtained for different agricultural cutting practice scenarios can be employed to create flood protection measures for flood-prone areas. The proposed methodology was applied to the downstream part of a small Mediterranean river basin in Crete, Greece.

    Noting the upstream positioning of sustainable food systems (SFS) to multiple global crises, the present review described examples of emerging and promising practices to support SFS-oriented education, practical training (PT) and continuing professional development (CPD) among trainees and public health practitioners (PHP). A secondary objective was to compile the evidence into practical considerations for educators, supervising practitioners and professional associations. A scoping review of the literature published between 2007 and 2017 was conducted in May 2017 using four databases: CINAHL, MEDLINE, Scopus and HSSA, along with bibliography hand-searching and expert consultation. Articles were screened for relevance and specificity by independent raters. Nineteen articles were included for analysis. Two-thirds of the articles related to dietitians and public health nutritionists. Emerging practices included curriculum-based considerations, incorporation of 'sustainability' within professional competencies and self-reflection related to SFS. Descriptions of SFS-related education, PT and CPD practices appeared largely in the literature from developed countries. Articles converged on the need for ecosystems, food systems and sustainability considerations within and across practice to support current and future practitioners. There is growing interest in SFS but guidance to support educators and preceptors is lacking. Updates to dietary guidelines to reflect issues of sustainability are a timely prompt to examine the education, training and development needs of trainees and PHP. Practical examples of emerging practices can empower PHP to promote SFS in all areas of practice. More research is needed to address identified gaps in the literature and to improve SFS-specific education, PT and CPD.

    Knowledge-based systems (KBS's) are in general use in a wide variety of domains, both commercial and government. As reliance on these types of systems grows, the need to assess their quality and validity reaches critical importance. As with any software, the reliability of a KBS can be directly attributed to the application of disciplined programming and testing practices throughout the development life-cycle. However, there are some essential differences between conventional software and KBSs, both in construction and use. The identification of these differences affect the verification and validation (V&V) process and the development of techniques to handle them. The recognition of these differences is the basis of considerable on-going research in this field. For the past three years IBM (Federal Systems Company - Houston) and the Software Technology Branch (STB) of NASA/Johnson Space Center have been working to improve the 'state of the practice' in V&V of Knowledge-based systems. This work was motivated by the need to maintain NASA's ability to produce high quality software while taking advantage of new KBS technology. To date, the primary accomplishment has been the development and teaching of a four-day workshop on KBS V&V. With the hope of improving the impact of these workshops, we also worked directly with NASA KBS projects to employ concepts taught in the workshop. This paper describes two projects that were part of this effort. In addition to describing each project, this paper describes problems encountered and solutions proposed in each case, with particular emphasis on implications for transferring KBS V&V technology beyond the NASA domain.

    Changes in environmental legislation and standards governing healthcare waste, such as the Hazardous Waste Regulations are expected to have a significant impact on healthcare waste quantities and costs in England and Wales. This paper presents findings from two award winning case study organizations, the Cardiff and Vale NHS Trust and the Cornwall NHS Trust on 'systems' they have employed for minimizing waste. The results suggest the need for the development and implementation of a holistic range of systems in order to develop best practice, including waste minimization strategies, key performance indicators, and staff training and awareness. The implications for the sharing of best practice from the two case studies are also discussed.

    2014-01-01

    Delays in care have been cited as one of the primary contributors of preventable mortality; thus, quality patient safety is often contingent upon the delivery of timely clinical care. Rapid response systems (RRSs) have been touted as one mechanism to improve the ability of suitable staff to respond to deteriorating patients quickly and appropriately. Rapid response systems are defined as highly skilled individual(s) who mobilize quickly to provide medical care in response to clinical deterioration. While there is mounting evidence that RRSs are a valid strategy for managing obstetric emergencies, reducing adverse events, and improving patient safety, there remains limited insight into the practices underlying the development and execution of these systems. Therefore, the purpose of this article was to synthesize the literature and answer the primary questions necessary for successfully developing, implementing, and evaluating RRSs within inpatient settings-the Who, What, When, Where, Why, and How of RRSs.

    Research shows that maternity care practices are important to promoting breastfeeding in the early post partum period; however, little is known about the association between maternity care practices and breastfeeding among different racial and ethnic groups. We examined the association between maternity care practices and breastfeeding duration to ≥10 weeks overall and among various racial and ethnic groups using data from the Pregnancy Risk Assessment and Monitoring System (PRAMS). PRAMS is a state, population-based surveillance system that collects information on maternal behaviors. We used maternity care practices data from 11 states and New York City with response rates ≥70% from 2004 to 2006. Multiple maternity care practices were examined and the analysis adjusted for demographic characteristics, participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), lifestyle, and infant variables. The outcome variable for multivariable analysis was breastfeeding duration to <10 weeks or ≥10 weeks. PRAMS data show that 22.1% of women did not breastfeed, about 27.7% breastfed for <10 weeks and 50.2% breastfed for ≥10 weeks. Breastfeeding patterns varied with white and Hispanic women reporting highest breastfeeding initiation and duration prevalence. Overall, practices positively associated with ≥10 duration were: breastfeeding initiated within the first hour after birth (adjusted OR [AOR] = 1.29; 95% CI: 1.16-1.45); fed breast milk only (AOR = 2.40; 95% CI: 2.15-2.68); breastfed on demand (AOR = 1.23; 95% CI 1.08-1.40) and receiving telephone support (AOR = 1.20; 95% CI: 1.03-1.39). Maternity care practices associated with breastfeeding to ≥10 weeks varied across three racial/ethnic groups. One practice, that of giving newborns breast milk only, was positively associated with breastfeeding duration of ≥10 weeks across all three groups. Maternity care practices associated with breastfeeding continuation

    This review of systems thinking (ST) case studies seeks to compile and analyse cases from ST literature and provide practitioners with a reference for ST in health practice. Particular attention was given to (1) reviewing the frequency and use of key ST terms, methods, and tools in the context of health, and (2) extracting and analysing longitudinal themes across cases. A systematic search of databases was conducted, and a total of 36 case studies were identified. A combination of integrative and inductive qualitative approaches to analysis was used. Most cases identified took place in high-income countries and applied ST retrospectively. The most commonly used ST terms were agent/stakeholder/actor (n = 29), interdependent/interconnected (n = 28), emergence (n = 26), and adaptability/adaptation (n = 26). Common ST methods and tools were largely underutilized. Social network analysis was the most commonly used method (n = 4), and innovation or change management history was the most frequently used tool (n = 11). Four overarching themes were identified; the importance of the interdependent and interconnected nature of a health system, characteristics of leaders in a complex adaptive system, the benefits of using ST, and barriers to implementing ST. This review revealed that while much has been written about the potential benefits of applying ST to health, it has yet to completely transition from theory to practice. There is however evidence of the practical use of an ST lens as well as specific methods and tools. With clear examples of ST applications, the global health community will be better equipped to understand and address key health challenges. © 2017 John Wiley & Sons, Ltd.

    Systemic lupus erythematosus (SLE) is a complex rheumatic multisystemic disease of autoimmune origin with significant potential morbidity and mortality. It is one of the most common autoimmune diseases with an estimated prevalence of 20-150 cases per 100,000 inhabitants. The clinical spectrum of SLE is wide and variable both in clinical manifestations and severity. This prompted the Spanish Ministry of Health, Social Services and Equality to promote and fund the development of a clinical practice guideline (CPG) for the clinical care of SLE patients within the Programme of CPG in the National Health System which coordinates GuiaSalud. This CPG is is intended as the reference tool in the Spanish National Health System in order to support the comprehensive clinical management of people with SLE by all health professionals involved, regardless of specialty and level of care, helping to standardize and improve the quality of clinical decisions in our context in order to improve the health outcomes of the people affected. The purpose of this document is to present and discuss the rationale of the recommendations on the general management of SLE, specifically, clinical follow-up, general therapeutic approach, healthy lifestyles, photoprotection, and training programmes for patients. These recommendations are based on the best available scientific evidence, on discussion and the consensus of expert groups. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    The purpose of this study was to test the feasibility of collecting valid and widely used health outcomes, including information concerning cost of care, using a Web-based patient-driven patient-reported outcome measure (PROM) collection process within a cohort of UK chiropractic practices. A Web-based PROM system (Care Response) was used. Patients with low back and neck pain were recruited from a group of chiropractic practices located in the United Kingdom. Information collected included demographic data, generic and condition-specific PROMs at the initial consultation and 90 days later, patient-reported experience measures, and additional health seeking to estimate costs of care. A group of 33 clinics provided information from a total of 1895 patients who completed baseline questionnaires with 844 (45%) completing the measures at 90-day follow-up. Subsequent outcomes suggest that more than 70% of patients improved over the course of treatment regardless of the outcome used. Using the baseline as a virtual counterfactual with respect to follow-up, we calculated quality-adjusted life years and the cost thereof resulting in a mean quality-adjusted life years gained of 0.8 with an average cost of £895 per quality-adjusted life year. Routine collection of PROMs, including information about cost, is feasible and can be achieved using an online system within a clinical practice environment. We describe a Web-based collection system and discuss the choice of measures leading to a comprehensive understanding of outcomes and costs in routine practice.

  12. Optimized Scheduling Technique of Null Subcarriers for Peak Power Control in 3GPP LTE Downlink

    Orthogonal frequency division multiple access (OFDMA) is a key multiple access technique for the long term evolution (LTE) downlink. However, high peak-to-average power ratio (PAPR) can cause the degradation of power efficiency. The well-known PAPR reduction technique, dummy sequence insertion (DSI), can be a realistic solution because of its structural simplicity. However, the large usage of subcarriers for the dummy sequences may decrease the transmitted data rate in the DSI scheme. In this paper, a novel DSI scheme is applied to the LTE system. Firstly, we obtain the null subcarriers in single-input single-output (SISO) and multiple-input multiple-output (MIMO) systems, respectively; then, optimized dummy sequences are inserted into the obtained null subcarrier. Simulation results show that Walsh-Hadamard transform (WHT) sequence is the best for the dummy sequence and the ratio of 16 to 20 for the WHT and randomly generated sequences has the maximum PAPR reduction performance. The number of near optimal iteration is derived to prevent exhausted iterations. It is also shown that there is no bit error rate (BER) degradation with the proposed technique in LTE downlink system.

    Aerobic oxidation reactions have been the focus of considerable attention, but their use in mainstream organic chemistry has been constrained by limitations in their synthetic scope and by practical factors, such as the use of pure O2 as the oxidant or complex catalyst synthesis. Here, we report a new (bpy)CuI/TEMPO catalyst system that enables efficient and selective aerobic oxidation of a broad range of primary alcohols, including allylic, benzylic and aliphatic derivatives, to the corresponding aldehydes using readily available reagents, at room temperature with ambient air as the oxidant. The catalyst system is compatible with a wide range of functional groups and the high selectivity for 1° alcohols enables selective oxidation of diols that lack protecting groups. PMID:21861488

    This paper explores how system-wide approaches to obesity prevention were 'theorised' and translated into practice in the 'Healthy Towns' programme implemented in nine areas in England. Semi-structured interviews with 20 informants, purposively selected to represent national and local programme development, management and delivery were undertaken. Results suggest that informants articulated a theoretical understanding of a system-wide approach to obesity prevention, but simplifying this complex task in the context of uncertainty over programme aims and objectives, and absence of a clear direction from the central government, resulted in local programmes relying on traditional multi-component approaches to programme delivery. The development of clear, practical guidance on implementation should form a central part of future system-wide approaches to obesity prevention. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Learning in practice disciplines suffers when gaps exist between classroom instruction and students' observations of routine clinical practices.(1) Academic institutions, therefore, have a strong interest in fostering the rapid and effective translation of evidence-based care techniques into routine practice. Long-term care (LTC) practice sites are particularly vulnerable to gaps between classroom teaching and how daily care is implemented, owing to the recent rapid advances in the scientific bases of care for frail older adults, the relative isolation of most LTC sites from academic settings,(2) and the relatively small number of registered nurses (RNs) available in LTC settings who can facilitate translation of research-based practices into care.(3) The aim of this project was to demonstrate the feasibility and value of an academic practice partnership to implement evidence-based approaches to solving resident care problems in LTC, as many scientifically proven practices hold promise for improving resident outcomes yet adoption is often slow.(4) We developed and implemented a clinical practice improvement process, based on diffusion of innovations theory and research,(5-8) to serve as a new model of academic-practice collaboration between a university school of nursing, LTC facility management and direct-care staff, as a means of developing high quality clinical sites for student rotations. The goal was to implement a sustainable evidence-based oral care program as an exemplar of how scientific evidence can be translated into LTC practice. This project focused on oral hygiene because the staff was dissatisfied with their existing resident oral care program, and an evidence-base for oral care in LTC existed that had not yet been incorporated into care routines. This article describes a systematic, replicable process for linking advanced practice registered nurse expertise with staff insights about care systems to reduce the gap between teaching and practice in
