An observational study of Donor Ex Vivo Lung Perfusion in UK lung transplantation: DEVELOP-UK

Background: Many patients awaiting lung transplantation die before a donor organ becomes available. Ex vivo lung perfusion (EVLP) allows initially unusable donor lungs to be assessed and reconditioned for clinical use. Objective: The objective of the Donor Ex Vivo Lung Perfusion in UK lung transplantation study was to evaluate the clinical effectiveness and cost-effectiveness of EVLP in increasing UK lung transplant activity. Design: A multicentre, unblinded, non-randomised, non-inferiority observational study to compare transplant outcomes between EVLP-assessed and standard donor lungs. Setting: Multicentre study involving all five UK officially designated NHS adult lung transplant centres. Participants: Patients aged ≥ 18 years with advanced lung disease accepted onto the lung transplant waiting list. Intervention: The study intervention was EVLP assessment of donor lungs before determining suitability for transplantation. Main outcome measures: The primary outcome measure was survival during the first 12 months following lung transplantation. Secondary outcome measures were patient-centred outcomes that are influenced by the effectiveness of lung transplantation and that contribute to the health-care costs. Results: Lungs from 53 donors unsuitable for standard transplant were assessed with EVLP, of which 18 (34%) were subsequently transplanted. A total of 184 participants received standard donor lungs. Owing to the early closure of the study, a non-inferiority analysis was not conducted. The Kaplan–Meier estimate of survival at 12 months was 0.67 [95% confidence interval (CI) 0.40 to 0.83] for the EVLP arm and 0.80 (95% CI 0.74 to 0.85) for the standard arm. The hazard ratio for overall 12-month survival in the EVLP arm relative to the standard arm was 1.96 (95% CI 0.83 to 4.67). Patients in the EVLP arm required ventilation for a longer period and stayed longer in an intensive therapy unit (ITU) than patients in the standard arm, but duration of overall hospital stay was similar in both groups. There was a higher rate of very early grade 3 primary graft dysfunction (PGD) in the EVLP arm, but rates of PGD did not differ between groups after 72 hours. The requirement for extracorporeal membrane oxygenation (ECMO) support was higher in the EVLP arm (7/18, 38.8%) than in the standard arm (6/184, 3.2%). There were no major differences in rates of chest radiograph abnormalities, infection, lung function or rejection by 12 months. The cost of EVLP transplants is approximately £35,000 higher than the cost of standard transplants, as a result of the cost of the EVLP procedure, and the increased ECMO use and ITU stay. Predictors of cost were quality of life on joining the waiting list, type of transplant and number of lungs transplanted. An exploratory model comparing a NHS lung transplant service that includes EVLP and standard lung transplants with one including only standard lung transplants resulted in an incremental cost-effectiveness ratio of £73,000. Interviews showed that patients had a good understanding of the need for, and the processes of, EVLP. If EVLP can increase the number of usable donor lungs and reduce waiting, it is likely to be acceptable to those waiting for lung transplantation. Study limitations include small numbers in the EVLP arm, limiting analysis to descriptive statistics and the EVLP protocol change during the study. Conclusions: Overall, one-third of donor lungs subjected to EVLP were deemed suitable for transplant. Estimated survival over 12 months was lower than in the standard group, but the data were also consistent with no difference in survival between groups. Patients receiving these additional transplants experience a higher rate of early graft injury and need for unplanned ECMO support, at increased cost. The small number of participants in the EVLP arm because of early study termination limits the robustness of these conclusions. The reason for the increased PGD rates, high ECMO requirement and possible differences in lung injury between EVLP protocols needs evaluation

Community hospitals and their services in the NHS: identifying transferable learning from international developments - scoping review, systematic review, country reports and case studies

Background: The notion of a community hospital in England is evolving from the traditional model of a local hospital staffed by general practitioners and nurses and serving mainly rural populations. Along with the diversification of models, there is a renewed policy interest in community hospitals and their potential to deliver integrated care. However, there is a need to better understand the role of different models of community hospitals within the wider health economy and an opportunity to learn from experiences of other countries to inform this potential. Objectives This study sought to (1) define the nature and scope of service provision models that fit under the umbrella term ‘community hospital’ in the UK and other high-income countries, (2) analyse evidence of their effectiveness and efficiency, (3) explore the wider role and impact of community engagement in community hospitals, (4) understand how models in other countries operate and asses their role within the wider health-care system, and (5) identify the potential for community hospitals to perform an integrative role in the delivery of health and social care. Methods A multimethod study including a scoping review of community hospital models, a linked systematic review of their effectiveness and efficiency, an analysis of experiences in Australia, Finland, Italy, Norway and Scotland, and case studies of four community hospitals in Finland, Italy and Scotland. Results The evidence reviews found that community hospitals provide a diverse range of services, spanning primary, secondary and long-term care in geographical and health system contexts. They can offer an effective and efficient alternative to acute hospitals. Patient experience was frequently reported to be better at community hospitals, and the cost-effectiveness of some models was found to be similar to that of general hospitals, although evidence was limited. Evidence from other countries showed that community hospitals provide a wide spectrum of health services that lie on a continuum between serving a ‘geographic purpose’ and having a specific population focus, mainly older people. Structures continue to evolve as countries embark on major reforms to integrate health and social care. Case studies highlighted that it is important to consider local and national contexts when looking at how to transfer models across settings, how to overcome barriers to integration beyond location and how the community should be best represented. Limitations The use of a restricted definition may have excluded some relevant community hospital models, and the small number of countries and case studies included for comparison may limit the transferability of findings for England. Although this research provides detailed insights into community hospitals in five countries, it was not in its scope to include the perspective of patients in any depth. Conclusions At a time when emphasis is being placed on integrated and community-based care, community hospitals have the potential to assume a more strategic role in health-care delivery locally, providing care closer to people’s homes. There is a need for more research into the effectiveness and cost-effectiveness of community hospitals, the role of the community and optimal staff profile(s).

Research utilisation and knowledge mobilisation in the commissioning and joint planning of public health interventions to reduce alcohol-related harms: a qualitative case design using a cocreation approach

Background: Considerable resources are spent on research to establish what works to improve the nation’s health. If the findings from this research are used, better health outcomes can follow, but we know that these findings are not always used. In public health, evidence of what works may not ‘fit’ everywhere, making it difficult to know what to do locally. Research suggests that evidence use is a social and dynamic process, not a simple application of research findings. It is unclear whether it is easier to get evidence used via a legal contracting process or within unified organisational arrangements with shared responsibilities. Objective: To work in cocreation with research participants to investigate how research is utilised and knowledge mobilised in the commissioning and planning of public health services to reduce alcohol-related harms. Design, setting and participants: Two in-depth, largely qualitative, cross-comparison case studies were undertaken to compare real-time research utilisation in commissioning across a purchaser–provider split (England) and in joint planning under unified organisational arrangements (Scotland) to reduce alcohol-related harms. Using an overarching realist approach and working in cocreation, case study partners (stakeholders in the process) picked the topic and helped to interpret the findings. In Scotland, the topic picked was licensing; in England, it was reducing maternal alcohol consumption. Methods: Sixty-nine interviews, two focus groups, 14 observations of decision-making meetings, two local feedback workshops (n = 23 and n = 15) and one national workshop (n = 10) were undertaken. A questionnaire (n = 73) using a Behaviourally Anchored Rating Scale was issued to test the transferability of the 10 main findings. Given the small numbers, care must be taken in interpreting the findings. Findings: Not all practitioners have the time, skills or interest to work in cocreation, but when there was collaboration, much was learned. Evidence included professional and tacit knowledge, and anecdotes, as well as findings from rigorous research designs. It was difficult to identify evidence in use and decisions were sometimes progressed in informal ways and in places we did not get to see. There are few formal evidence entry points. Evidence (prevalence and trends in public health issues) enters the process and is embedded in strategic documents to set priorities, but local data were collected in both sites to provide actionable messages (sometimes replicating the evidence base). Conclusions: Two mid-range theories explain the findings. If evidence has saliency (relates to ‘here and now’ as opposed to ‘there and then’) and immediacy (short, presented verbally or visually and with emotional appeal) it is more likely to be used in both settings. A second mid-range theory explains how differing tensions pull and compete as feasible and acceptable local solutions are pursued across stakeholders. Answering what works depends on answering for whom and where simultaneously to find workable (if temporary) ‘blends’. Gaining this agreement across stakeholders appeared more difficult across the purchaser–provider split, because opportunities to interact were curtailed; however, more research is needed. Funding: This study was funded by the Health Services and Delivery Research programme of the National Institute for Health Research

A systematic review of trend studies of women seeking termination of pregnancy

This article reports a systematic review of trend studies (1995-2006) that answers five questions: What are the patterns of: (1) age of women seeking termination of pregnancy, (2) first ever pregnancy ending in a termination, (3) contraception usage at the time of conception, (4) contraception chosen immediately post-operatively and (5) referral sources to termination of pregnancy services? Background: Fertility patterns are changing and there is evidence to indicate that numbers of older women conceiving for the first time is increasing. At the same time there are new methods of contraception widely available. Little is known about the implications of these changes on termination patterns. Design An extensive electronic search of databases such as CINAHL, MEDLINE® In–Process (OVID) and was conducted from January 1995 - June 2006 for trend studies in pregnancy terminations. Methods: Articles chosen were based on trend studies greater than five years, contained primary quantitative research and official government statistical reports. Results: Results of the search showed age was unable to be compared due to the many variations in measurements and time periods, there was only limited research worldwide of trends in contraception at the time of conception in relation to a termination of pregnancy. Additionally, there were no studies worldwide in the past 11 years which specifically examined trends in the characteristics of the number of first ever pregnancies which ended in a termination, contraception choices post-operative of a termination of pregnancy, or referral source to a termination of pregnancy provider. Conclusion: Little is reported in the literature on trends in the five characteristics related to pregnancy termination. Relevance to clinical practice Evidence about the changing patterns of women seeking pregnancy termination is needed to inform policy and practice and to ensure that health promotion strategies are underpinned by accurate information that reflects the needs of the populations of women in relation to their reproductive health

Cocaine/crack cocaine consumption, treatment demand, seizures, related offences, prices, average purity levels and deaths in the UK (1990-2004)

“The final, definitive version of this article has been published in the Journal, Journal of Psychopharmacology, 22 (1), 2008, on SAGE Journals Online: http://online.sagepub.com/ - Copyright British Association for Psychopharmacology" DOI: 10.1177/0269881107079170A recent trend of escalating use of cocaine/crack cocaine was observed in the UK. The number of mentions on death certificates; last year use of cocaine; treatment demand, number of drug offenders, seizures, prices and average purity levels were the indicators used for this descriptive and correlational study. Figures ( 1990-2004) were taken from official UK sources. A total of 1022 cocaine/crack cocaine death mentions ( i.e. deaths from any cause where the presence of cocaine/ crack cocaine was also detected) were identified, with cocaine/ crack cocaine being the sole drug mentioned in 36% of cases. The number of cocaine/ crack cocaine death mentions showed a year-on-year increase and correlated positively with the following cocaine ( powder) figures: last year use ( p < 0.001); number of offenders ( p < 0.001) and number of seizures ( p < 0.001), but correlated negatively with price ( p < 0.001). Furthermore, the number of cocaine/ crack cocaine death mentions correlated positively with the number of crack offenders ( p < 0.001) and seizures ( p < 0.001), but correlated negatively with both crack purity ( p < 0.001) and price ( p < 0.05). With conditions of increasing drug availability having been met in the UK, decrease in cocaine prices were associated with higher consumption levels and this, in turn, contributed to the increase in number of cocaine-related fatalities. There are limitations with the information collected, since no distinction is usually made on medical death certificates between cocaine and crack cocaine. The present study being an ecological one, it proved difficult to address the role of confounding variables that may well explain some of the associations observed.Peer reviewe
