Chiral phase transition in a covariant nonlocal NJL model

The properties of the chiral phase transition at finite temperature and chemical potential are investigated within a nonlocal covariant extension of the Nambu-Jona-Lasinio model based on a separable quark-quark interaction. We consider both the situation in which the Minkowski quark propagator has poles at real energies and the case where only complex poles appear. In the literature, the latter has been proposed as a realization of confinement. In both cases, the behaviour of the physical quantities as functions of T and \mu is found to be quite similar. In particular, for low values of T the chiral transition is always of first order and, for finite quark masses, at certain "end point" the transition turns into a smooth crossover. In the chiral limit, this "end point" becomes a "tricritical" point. Our predictions for the position of these points are similar, although somewhat smaller, than previous estimates. Finally, the relation between the deconfining transition and chiral restoration is also discussed.Comment: 11 pages, 2 figures. Figures modified, minor changes in the text. To be published in Phys.

Advance directives in European long-term care facilities : a cross-sectional survey

Background: End-of-life care practices in long-term care facilities (LTCFs) are the focus of growing attention in Europe, due to rapidly increasing number of older persons living in LTCFs. The knowledge about end-of-life discussions or existence of written advance directives in the European LTCFs is scarce. This study's aim is to investigate the prevalence of written advance directives and their sociodemographic associates, among recently deceased LTCF residents, in six European countries. Methods: Data from the European Union-funded PACE database were collected from 322 LTCFs in six European countries in 2014. The assessments were performed by using two questionnaires designed for LTCF administrative staff and for staff member.LTCFs were selected within each country by using proportional stratified random sampling procedure. Facilities with certain types and sizes were included from each country.Multilevel multivariate analyses were performed to evaluate associations between written advance directives and selected predictors. Results: In total, 32.5 % of the 1384 deceased LTCF residents had a written advance directive with a range from 0% to 77 % between countries. The proportion of the most common advance directive, 'Do not resuscitate in case of cardiac or respiratory arrest (DNR)', varied correspondingly from 0% to 75%.LTCF type (OR 2.86 95% CI 1.59 to 5.23) and capability of expressing at the time of admission (OR 3.26 95% CI 2.26 to 4.71) were the independent predictors for advance directive. Residents living in LTCFs where physician was available were less likely to have advance directive compared with residents from LTCFs where physician was not available. Conclusion: Extensive differences for prevalence of written advance directive exist between countries among older LTCF residents in Europe. Timely and appropriate response to LTCF resident's health needs and preferences efforts advance care planning

Consensus on treatment for residents in long-term care facilities : perspectives from relatives and care staff in the PACE cross-sectional study in 6 European countries

Background: In long-term care facilities often many care providers are involved, which could make it difficult to reach consensus in care. This may harm the relation between care providers and can complicate care. This study aimed to describe and compare in six European countries the degree of consensus among everyone involved in care decisions, from the perspective of relatives and care staff. Another aim was to assess which factors are associated with reporting that full consensus was reached, from the perspective of care staff and relatives.Methods: In Belgium, England, Finland, Italy, the Netherlands and Poland a random sample of representative long-term care facilities reported all deaths of residents in the previous three months (n = 1707). This study included residents about whom care staff (n = 1284) and relatives (n = 790) indicated in questionnaires the degree of consensus among all involved in the decision or care process. To account for clustering on facility level, Generalized Estimating Equations were conducted to analyse the degree of consensus across countries and factors associated with full consensus.Results: Relatives indicated full consensus in more than half of the residents in all countries (NL 57.9% - EN 68%), except in Finland (40.7%). Care staff reported full consensus in 59.5% of residents in Finland to 86.1% of residents in England. Relatives more likely reported full consensus when: the resident was more comfortable or talked about treatment preferences, a care provider explained what palliative care is, family-physician communication was well perceived, their relation to the resident was other than child (compared to spouse/partner) or if they lived in Poland or Belgium (compared to Finland). Care staff more often indicated full consensus when they rated a higher comfort level of the resident, or if they lived in Italy, the Netherland, Poland or England (compared to Finland).Conclusions: In most countries the frequency of full consensus among all involved in care decisions was relatively high. Across countries care staff indicated full consensus more often and no consensus less often than relatives. Advance care planning, comfort and good communication between relatives and care professionals could play a role in achieving full consensus

Technical-efficiency analysis of end-of-life care in long-term care facilities within Europe : a cross-sectional study of deceased residents in 6 EU countries (PACE)

Background : An ageing population in the EU leads to a higher need of long-term institutional care at the end of life. At the same time, healthcare costs rise while resources remain limited. Consequently, an urgency to extend our knowledge on factors affecting efficiency of long-term care facilities (LTCFs) arises. This study aims to investigate and explain variation in technical efficiency of end-of-life care within and between LTCFs of six EU countries: Belgium (Flanders), England, Finland, Italy, the Netherlands and Poland. In this study, technical efficiency reflects the LTCFs' ability to obtain maximal quality of life (QoL) and quality of dying (QoD) for residents from a given set of resource inputs (personnel and capacity). Methods : Cross-sectional data were collected by means of questionnaires on deceased residents identified by LTCFs over a three-month period. An output-oriented data-envelopment analysis (DEA) was performed, producing efficiency scores, incorporating personnel and capacity as input and QoL and QoD as output. Scenario analysis was conducted. Regression analysis was performed on explanatory (country, LTCF type, ownership, availability of palliative care and opioids) and case mix (disease severity) variables. Results : 133 LTCFs of only one type (onsite nurses and offsite GPs) were considered in order to reduce heterogeneity. Variation in LTCF efficiency was found across as well as within countries. This variation was not explained by country, ownership, availability of palliative care or opioids. However, in the 'hands-on care at the bedside' scenario, i.e. only taking into account nursing and care assistants as input, Poland (p = 0.00) and Finland (p = 0.04) seemed to be most efficient. Conclusions : Efficiency of LTCFs differed extensively across as well as within countries, indicating room for considerable efficiency improvement. Our findings should be interpreted cautiously, as comprehensive comparative EU-wide research is challenging as it is influenced by many factors

Decreased costs and retained QoL due to the ‘PACE Steps to Success’ intervention in LTCFs : cost-effectiveness analysis of a randomized controlled trial

BACKGROUND: The number of residents in long-term care facilities (LTCFs) in need of palliative care is growing in the Western world. Therefore, it is foreseen that significantly higher percentages of budgets will be spent on palliative care. However, cost-effectiveness analyses of palliative care interventions in these settings are lacking. Therefore, the objective of this paper was to assess the cost-effectiveness of the 'PACE Steps to Success' intervention. PACE (Palliative Care for Older People) is a 1-year palliative care programme aiming at integrating general palliative care into day-to-day routines in LTCFs, throughout seven EU countries. METHODS: A cluster RCT was conducted. LTCFs were randomly assigned to intervention or usual care. LTCFs reported deaths of residents, about whom questionnaires were filled in retrospectively about resource use and quality of the last month of life. A health care perspective was adopted. Direct medical costs, QALYs based on the EQ-5D-5L and costs per quality increase measured with the QOD-LTC were outcome measures. RESULTS: Although outcomes on the EQ-5D-5L remained the same, a significant increase on the QOD-LTC (3.19 points, p value 0.00) and significant cost-savings were achieved in the intervention group (€983.28, p value 0.020). The cost reduction mainly resulted from decreased hospitalization-related costs (€919.51, p value 0.018). CONCLUSIONS: Costs decreased and QoL was retained due to the PACE Steps to Success intervention. Significant cost savings and improvement in quality of end of life (care) as measured with the QOD-LTC were achieved. A clinically relevant difference of almost 3 nights shorter hospitalizations in favour of the intervention group was found. This indicates that timely palliative care in the LTCF setting can prevent lengthy hospitalizations while retaining QoL. In line with earlier findings, we conclude that integrating general palliative care into daily routine in LTCFs can be cost-effective. TRIAL REGISTRATION: ISRCTN14741671

Quality of dying and quality of end-of-life care of nursing home residents in six countries:an epidemiological study

Background:Nursing homes are among the most common places of death in many countries. Aim:To determine the quality of dying and end-of-life care of nursing home residents in six European countries.Design:Epidemiological survey in a proportionally stratified random sample of nursing homes. We identified all deaths of residents of the preceding 3-month period. Main outcomes: quality of dying in the last week of life (measured using End-of-Life in Dementia Scales – Comfort Assessment while Dying (EOLD-CAD)); quality of end-of-life care in the last month of life (measured using Quality of Dying in Long-Term Care (QoD-LTC) scale). Higher scores indicate better quality.Setting/participants:Three hundred and twenty-two nursing homes in Belgium, Finland, Italy, the Netherlands, Poland and England. Participants were staff (nurses or care assistants) most involved in each resident’s care.Results:Staff returned questionnaires regarding 1384 (81.6%) of 1696 deceased residents. The End-of-Life in Dementia Scales – Comfort Assessment while Dying mean score (95% confidence interval) (theoretical 14–42) ranged from 29.9 (27.6; 32.2) in Italy to 33.9 (31.5; 36.3) in England. The Quality of Dying in Long-Term Care mean score (95% confidence interval) (theoretical 11–55) ranged from 35.0 (31.8; 38.3) in Italy to 44.1 (40.7; 47.4) in England. A higher End-of-Life in Dementia Scales – Comfort Assessment while Dying score was associated with country (p = 0.027), older age (p = 0.012), length of stay ⩾1 year (p = 0.034), higher functional status (p < 0.001). A higher Quality of Dying in Long-Term Care score was associated with country (p < 0.001), older age (p < 0.001), length of stay ⩾1 year (p < 0.001), higher functional status (p = 0.002), absence of dementia (p = 0.001), death in nursing home (p = 0.033).Conclusion:The quality of dying and quality of end-of-life care in nursing homes in the countries studied are not optimal. This includes countries with high levels of palliative care development in nursing homes such as Belgium, the Netherlands and England

Care staff's self-efficacy regarding end-of-life communication in the long-term care setting:Results of the PACE cross-sectional study in six European countries

Background: An important part of palliative care is discussing preferences at end of life, however such conversations may not often occur. Care staff with greater self-efficacy towards end-of-life communication are probably more likely to have such discussions, however, there is a lack of research on self-efficacy towards end-of-life discussions among long-term care staff in Europe and related factors. Objectives: Firstly, to describe and compare the self-efficacy level of long-term care staff regarding end-of-life communication across six countries; secondly, to analyse characteristics of staff and facilities which are associated to self-efficacy towards end-of-life communication. Design: Cross-sectional survey. Settings: Long-term care facilities in Belgium, England, Finland, Italy, the Netherlands and Poland (n = 290). Participants: Nurses and care assistants (n = 1680) completed a self-efficacy scale and were included in the analyses. Methods: Care staff rated their self-efficacy (confidence in their own ability) on a scale of 0 (cannot do at all) to 7 -(certain can do) of the 8-item communication subscale of the Self-efficacy in End-of-Life Care survey. Staff characteristics included age, gender, professional role, education level, training in palliative care and years working in direct care. Facility characteristics included facility type and availability of palliative care guidelines, palliative care team and palliative care advice. Analyses were conducted using Generalized Estimating Equations, to account for clustering of data at facility level. Results: Thde proportion of staff with a mean self-efficacy score >5 was highest in the Netherlands (76.4%), ranged between 55.9% and 60.0% in Belgium, Poland, England and Finland and was lowest in Italy (29.6%). Higher levels of self-efficacy (>5) were associated with: staff over 50 years of age (OR 1.86 95% CI[1.30–2.65]); nurses (compared to care assistants) (1.75 [1.20–2.54]); completion of higher secondary or tertiary education (respectively 2.22 [1.53–3.21] and 3.11 [2.05–4.71]; formal palliative care training (1.71 [1.32–2.21]); working in direct care for over 10 years (1.53 [1.14–2.05]); working in a facility with care provided by onsite nurses and care assistants and offsite physicians (1.86 [1.30–2.65]); and working in a facility where guidelines for palliative care were available (1.39 [1.03–1.88]). Conclusion: Self-efficacy towards end-of-life communication was most often low in Italy and most often high in the Netherlands. In all countries, low self-efficacy was found relatively often for discussion of prognosis. Palliative care education and guidelines for palliative care could improve the self-efficacy of care staff

STOPPFall (Screening Tool of Older Persons Prescriptions in older adults with high fall risk): a Delphi study by the EuGMS Task and Finish Group on Fall-Risk-Increasing Drugs.

To access publisher's full text version of this article, please click on the hyperlink in Additional Links field or click on the hyperlink at the top of the page marked DownloadBackground: Healthcare professionals are often reluctant to deprescribe fall-risk-increasing drugs (FRIDs). Lack of knowledge and skills form a significant barrier and furthermore, there is no consensus on which medications are considered as FRIDs despite several systematic reviews. To support clinicians in the management of FRIDs and to facilitate the deprescribing process, STOPPFall (Screening Tool of Older Persons Prescriptions in older adults with high fall risk) and a deprescribing tool were developed by a European expert group. Methods: STOPPFall was created by two facilitators based on evidence from recent meta-analyses and national fall prevention guidelines in Europe. Twenty-four panellists chose their level of agreement on a Likert scale with the items in the STOPPFall in three Delphi panel rounds. A threshold of 70% was selected for consensus a priori. The panellists were asked whether some agents are more fall-risk-increasing than others within the same pharmacological class. In an additional questionnaire, panellists were asked in which cases deprescribing of FRIDs should be considered and how it should be performed. Results: The panellists agreed on 14 medication classes to be included in the STOPPFall. They were mostly psychotropic medications. The panellists indicated 18 differences between pharmacological subclasses with regard to fall-risk-increasing properties. Practical deprescribing guidance was developed for STOPPFall medication classes. Conclusion: STOPPFall was created using an expert Delphi consensus process and combined with a practical deprescribing tool designed to optimise medication review. The effectiveness of these tools in falls prevention should be further evaluated in intervention studies.
