    This article presents a process evaluation of the implementation and refinement of a patient experience toolkit (PET) by action researchers in six hospital wards in the English National Health Service (NHS). An initial assumption that health care professionals (HCPs) would use PET to improve patient experience proved unrealistic due to staff and service pressures. However, the action researchers' facilitation of PET and their support during the implementation of quality improvement efforts filled in for HCPs' lack of time. The findings suggest that the PET can be a successful guide for skilled facilitators working with HCPs, although excessive staff pressures should be avoided. Toolkits designed for implementation by HCPs should, therefore, be used sparingly; a more appropriate target audience may be facilitators. Furthermore, while the potential of action research is confirmed by this evaluation, HCPs' time to engage in service improvement is found to moderate the success of this increasingly prominent methodology

    Advancing Complexity Theory in Health Services Research: The Logic of Logic Models

    Background: Logic models are commonly used in evaluations to represent the causal processes through which interventions produce outcomes, yet significant debate is currently taking place over whether they can describe complex interventions which adapt to context. This paper assesses the logic models used in healthcare research from a complexity perspective. A typology of existing logic models is proposed, as well as a formal methodology for deriving more flexible and dynamic logic models. Analysis: Various logic model types were tested as part of an evaluation of a complex Patient Experience Toolkit (PET) intervention, developed and implemented through action research across six hospital wards/departments in the English NHS. Three dominant types of logic model were identified, each with certain strengths but ultimately unable to accurately capture the dynamics of PET. Hence, a fourth logic model type was developed to express how success hinges on the adaption of PET to its delivery settings. Aspects of the Promoting Action on Research Implementation in Health Services (PARIHS) model were incorporated into a traditional logic model structure to create a dynamic “type 4” logic model that can accommodate complex interventions taking on a different form in different settings. Conclusion: Logic models can be used to model complex interventions that adapt to context but more flexible and dynamic models are required. An implication of this is that how logic models are used in healthcare research may have to change. Using logic models to forge consensus among stakeholders and/or provide precise guidance across different settings will be inappropriate in the case of complex interventions that adapt to context. Instead, logic models for complex interventions may be targeted at facilitators to enable them to prospectively assess the settings they will be working in and to develop context-sensitive facilitation strategies. Researchers should be clearas to why they are using a logic model and experiment with different models to ensure they have the correct type

    The Leeds Evaluation of Efficacy of Detoxification Study (LEEDS) prisons project pilot study: protocol for a randomised controlled trial comparing dihydrocodeine and buprenorphine for opiate detoxification

    Background In the United Kingdom (UK), there is an extensive market for the class 'A' drug heroin. Many heroin users spend time in prison. People addicted to heroin often require prescribed medication when attempting to cease their drug use. The most commonly used detoxification agents in UK prisons are buprenorphine, dihydrocodeine and methadone. However, national guidelines do not state a detoxification drug of choice. Indeed, there is a paucity of research evaluating the most effective treatment for opiate detoxification in prisons. This study seeks to address the paucity by evaluating routinely used interventions amongst drug using prisoners within UK prisons. Methods/Design The Leeds Evaluation of Efficacy of Detoxification Study (LEEDS) Prisons Pilot Study will use randomised controlled trial methodology to compare the open use of buprenorphine and dihydrocodeine for opiate detoxification, given in the context of routine care, within HMP Leeds. Prisoners who are eligible and give informed consent will be entered into the trial. The primary outcome measure will be abstinence status at five days post detoxification, as determined by a urine test. Secondary outcomes during the detoxification and then at one, three and six months post detoxification will be recorded

    Anomalous quantum reflection of Bose-Einstein condensates from a silicon surface: the role of dynamical excitations

    Get PDF
    We investigate the effect of inter-atomic interactions on the quantum-mechanical reflection of Bose-Einstein condensates from regions of rapid potential variation. The reflection process depends critically on the density and incident velocity of the condensate. For low densities and high velocities, the atom cloud has almost the same form before and after reflection. Conversely, at high densities and low velocities, the reflection process generates solitons and vortex rings that fragment the condensate. We show that this fragmentation can explain the anomalously low reflection probabilities recently measured for low-velocity condensates incident on a silicon surface.Comment: 5 figures, 5 pages, references correcte

    Using patient experience data to develop a patient experience toolkit to improve hospital care: a mixed-methods study

    Get PDF
    Background Patients are increasingly being asked to provide feedback about their experience of health-care services. Within the NHS, a significant level of resource is now allocated to the collection of this feedback. However, it is not well understood whether or not, or how, health-care staff are able to use these data to make improvements to future care delivery. Objective To understand and enhance how hospital staff learn from and act on patient experience (PE) feedback in order to co-design, test, refine and evaluate a Patient Experience Toolkit (PET). Design A predominantly qualitative study with four interlinking work packages. Setting Three NHS trusts in the north of England, focusing on six ward-based clinical teams (two at each trust). Methods A scoping review and qualitative exploratory study were conducted between November 2015 and August 2016. The findings of this work fed into a participatory co-design process with ward staff and patient representatives, which led to the production of the PET. This was primarily based on activities undertaken in three workshops (over the winter of 2016/17). Then, the facilitated use of the PET took place across the six wards over a 12-month period (February 2017 to February 2018). This involved testing and refinement through an action research (AR) methodology. A large, mixed-methods, independent process evaluation was conducted over the same 12-month period. Findings The testing and refinement of the PET during the AR phase, with the mixed-methods evaluation running alongside it, produced noteworthy findings. The idea that current PE data can be effectively triangulated for the purpose of improvement is largely a fallacy. Rather, additional but more relational feedback had to be collected by patient representatives, an unanticipated element of the study, to provide health-care staff with data that they could work with more easily. Multidisciplinary involvement in PE initiatives is difficult to establish unless teams already work in this way. Regardless, there is merit in involving different levels of the nursing hierarchy. Consideration of patient feedback by health-care staff can be an emotive process that may be difficult initially and that needs dedicated time and sensitive management. The six ward teams engaged variably with the AR process over a 12-month period. Some teams implemented far-reaching plans, whereas other teams focused on time-minimising ‘quick wins’. The evaluation found that facilitation of the toolkit was central to its implementation. The most important factors here were the development of relationships between people and the facilitator’s ability to navigate organisational complexity. Limitations The settings in which the PET was tested were extremely diverse, so the influence of variable context limits hard conclusions about its success. Conclusions The current manner in which PE feedback is collected and used is generally not fit for the purpose of enabling health-care staff to make meaningful local improvements. The PET was co-designed with health-care staff and patient representatives but it requires skilled facilitation to achieve successful outcomes.

    Nonlinear resonant tunneling in systems coupled to quantum reservoirs

    Full text link
    An adiabatic approximation in terms of instantaneous resonances is developed to study the steady-state and time-dependent transport of interacting electrons in biased resonant tunneling heterostructures. The resulting model consists of quantum reservoirs coupled to regions where the system is described by nonlinear ordinary differential equations and has a general conceptual interest.Comment: 4 pages, 3 postscript figure

    Creation of solitons and vortices by Bragg reflection of Bose-Einstein condensates in an optical lattice

    Get PDF
    We study the dynamics of Bose-Einstein condensates in an optical lattice and harmonic trap. The condensates are set in motion by displacing the trap and initially follow simple semiclassical paths, shaped by the lowest energy band. Above a critical displacement, the condensate undergoes Bragg reflection. For high atom densities, the first Bragg reflection generates a train of solitons and vortices, which destabilize the condensate and trigger explosive expansion. At lower densities, soliton and vortex formation requires multiple Bragg reflections, and damps the center-of-mass motion.Comment: 5 pages including 5 figures (for higher resolution figures please email the authors
