Prompt atmospheric neutrino fluxes: perturbative QCD models and nuclear effects

We evaluate the prompt atmospheric neutrino flux at high energies using three different frameworks for calculating the heavy quark production cross section in QCD: NLO perturbative QCD, $k_T$ factorization including low-$x$ resummation, and the dipole model including parton saturation. We use QCD parameters, the value for the charm quark mass and the range for the factorization and renormalization scales that provide the best description of the total charm cross section measured at fixed target experiments, at RHIC and at LHC. Using these parameters we calculate differential cross sections for charm and bottom production and compare with the latest data on forward charm meson production from LHCb at $7$ TeV and at $13$ TeV, finding good agreement with the data. In addition, we investigate the role of nuclear shadowing by including nuclear parton distribution functions (PDF) for the target air nucleus using two different nuclear PDF schemes. Depending on the scheme used, we find the reduction of the flux due to nuclear effects varies from $10\%$ to $50 \%$ at the highest energies. Finally, we compare our results with the IceCube limit on the prompt neutrino flux, which is already providing valuable information about some of the QCD models.Comment: 61 pages, 25 figures, 11 table

A qualitative study of the views of patients with long-term conditions on family doctors in Hong Kong

<b>Background</b> Primary care based management of long-term conditions (LTCs) is high on the international healthcare agenda, including the Asia-Pacific region. Hong Kong has a 'mixed economy' healthcare system with both public and private sectors with a range of types of primary care doctors. Recent Hong Kong Government policy aims to enhance the management of LTCs in primary care possibly based on a 'family doctor' model. Patients' views on this are not well documented and the aim of the present study was to explore the views of patients with LTCs on family doctors in Hong Kong.<p></p> <b>Methods</b> The views of patients (with a variety of LTCs) on family doctors in Hong Kong were explored. Two groups of participants were interviewed; a) those who considered themselves as having a family doctor, b) those who considered themselves as not having a family doctor (either with a regular primary care doctor but not a family doctor or with no regular primary care doctor). In-depth individual semi-structured interviews were carried out with 28 participants (10 with a family doctor, 10 with a regular doctor, and 8 with no regular doctor) and analysed using the constant comparative method.<p></p> <b>Results</b> Participants who did not have a family doctor were familiar with the concept but regarded it as a 'luxury item' for the rich within the private healthcare system. Those with a regular family doctor (all private) regarded having one as important to their and their family's health. Participants in both groups felt that as well as the more usual family medicine specialist or general practitioner, traditional Chinese medicine practitioners also had the potential to be family doctors. However most participants attended the public healthcare system for management of their LTCs whether they had a family doctor or not. Cost, perceived need, quality, trust, and choice were all barriers to the use of family doctors for the management of their LTCs.<p></p> <b>Conclusions</b> Important barriers to the adoption of a 'family doctor' model of management of LTCs exist in Hong Kong. Effective policy implementation seems unlikely unless these complex barriers are addressed

Developing and Implementing a Framework for System Level Measures: lessons from New Zealand

Background: Measuring performance is now the norm in health systems. System Level Measures (SLMs), implemented at New Zealand’s Counties Manukau Health (CMH) are designed to support quality improvement activities undertaken across the health system using only a small set of measures. While the healthcare and performance measurement literature contains information regarding the facilitators and barriers to quality improvement initiatives, there is an absence of studies into whether these factors are germane to the establishment and implementation of a SLM framework. Methods: A purposive sample of thirteen senior managers and clinicians involved in the construction and implementation of SLMs were invited to participate. Semi-structured telephone interviews were completed and recordings transcribed verbatim. Transcriptions were thematically analysed using a general inductive approach. Findings: In total, ten interviews took place. Six facilitative themes were identified including: dispersed and focused leadership; communication; data; alignment of the measures with organisational strategic data; alignment of the measures with organisational strategic plans and values; stakeholder engagement; and a dedicated project team. Conversely, five themes were identified that hindered the process. These were: reaching consensus; perfection versus pragmatism; duplication and process burden; achieving buy-in and workload. Discussion: The factors that facilitate and hinder establishing and implementing a framework of SLMs are common to other quality improvement approaches. However, this study demonstrated that these factors were also germane to SLMs. These findings are of particular relevance as researchers and policy makers elsewhere increasingly aim to adopt measurement arrangements for health systems that address equity, safety, quality, access and cost.

Creating sustainable health care systems: Agreeing social (societal) priorities through public participation

PURPOSE: In order to create sustainable health systems, many countries are introducing ways to prioritise health services underpinned by a process of health technology assessment. While this approach requires technical judgements of clinical effectiveness and cost effectiveness, these are embedded in a wider set of social (societal) value judgements, including fairness, responsiveness to need, non-discrimination and obligations of accountability and transparency. Implementing controversial decisions faces legal, political and public challenge. To help generate acceptance for the need for health prioritisation and the resulting decisions, the purpose of this paper is to develop a novel way of encouraging key stakeholders, especially patients and the public, to become involved in the prioritisation process. DESIGN/METHODOLOGY/APPROACH: Through a multidisciplinary collaboration involving a series of international workshops, ethical and political theory (including accountability for reasonableness) have been applied to develop a practical way forward through the creation of a values framework. The authors have tested this framework in England and in New Zealand using a mixed-methods approach. FINDINGS: A social values framework that consists of content and process values has been developed and converted into an online decision-making audit tool. RESEARCH LIMITATIONS/IMPLICATIONS: The authors have developed an easy to use method to help stakeholders (including the public) to understand the need for prioritisation of health services and to encourage their involvement. It provides a pragmatic way of harmonising different perspectives aimed at maximising health experience. PRACTICAL IMPLICATIONS: All health care systems are facing increasing demands within finite resources. Although many countries are introducing ways to prioritise health services, the decisions often face legal, political, commercial and ethical challenge. The research will help health systems to respond to these challenges. SOCIAL IMPLICATIONS: This study helps in increasing public involvement in complex health challenges. ORIGINALITY/VALUE: No other groups have used this combination of approaches to address this issue
