Exploring the association between primary care efficiency and health system characteristics across European countries: a two-stage data envelopment analysis

BACKGROUND

Primary care is widely seen as a core component of resilient and sustainable health systems, yet its efficiency is not well understood and there is a lack of evidence about how primary care efficiency is associated with health system characteristics. We examine this issue through the lens of diabetes care, which has a well-established evidence base for effective treatment and has previously been used as a tracer condition to measure health system performance.

METHODS

We developed a conceptual framework to guide the analysis of primary care efficiency. Using data on 18 European countries during 2010-2016 from several international databases, we applied a two-stage data envelopment analysis to estimate (i) technical efficiency of primary care and (ii) the association between efficiency and health system characteristics.

RESULTS

Countries varied widely in terms of primary care efficiency, with efficiency scores depending on the range of population characteristics adjusted for. Higher efficiency was associated with bonus payments for the prevention and management of chronic conditions, nurse-led follow-up, and a financial incentive or requirement for patients to obtain a referral to specialist care. Conversely, lower efficiency was associated with higher rates of curative care beds and financial incentives for patients to register with a primary care provider.

CONCLUSIONS

Our results underline the importance of considering differences in population characteristics when comparing country performance on primary care efficiency. We highlight several policies that could enhance the efficiency of primary care. Improvements in data collection would enable more comprehensive assessments of primary care efficiency across countries, which in turn could more effectively inform policymaking.

The role of multimorbidity and socio-economic characteristics as potential risk factors for Long Covid: evidence from the multilevel analysis of the Survey of Health, Ageing and Retirement in Europe's corona surveys (2020-2021)

BACKGROUND

A substantial proportion of individuals continue experiencing persistent symptoms following the acute stage of their Covid-19 illness. However, there is a shortage of population-based studies on Long Covid risk factors.

OBJECTIVE

To estimate the prevalence of Long Covid in the population of middle-aged and older Europeans having contracted Covid-19 and to assess the role of multimorbidity and socio-economic characteristics as potential risk factors of Long Covid.

METHODS

A population-based longitudinal prospective study involving a sample of respondents 50 years and older (n = 4,004) from 27 countries who participated in the 2020 and 2021 Survey of Health, Ageing and Retirement in Europe (SHARE), in particular the Corona Surveys. Analyses were conducted by a multilevel (random intercept) hurdle negative binomial model.

RESULTS

Overall, 71.6% (95% confidence interval = 70.2-73.0%) of the individuals who contracted Covid-19 had at least one symptom of Long Covid up to 12 months after the infection, with an average of 3.06 (standard deviation = 1.88) symptoms. There were significant cross-country differences in the prevalence of Long Covid and number of symptoms. Higher education and being a man were associated with a lower risk of Long Covid, whilst being employed was associated with a higher risk of having Long Covid. Multimorbidity was associated with a higher number of symptoms and older age was associated with a lower number of symptoms.

CONCLUSION

Our results provide evidence on the substantial burden of Long Covid in Europe. Individuals who contracted Covid-19 may require long-term support or further medical intervention, putting additional pressure on national health care systems.

Machine learning for predicting neurodegenerative diseases in the general older population: a cohort study

BACKGROUND

In the older general population, neurodegenerative diseases (NDs) are associated with increased disability, decreased physical and cognitive function. Detecting risk factors can help implement prevention measures. Using deep neural networks (DNNs), a machine-learning algorithm could be an alternative to Cox regression in tabular datasets with many predictive features. We aimed to compare the performance of different types of DNNs with regularized Cox proportional hazards models to predict NDs in the older general population.

METHODS

We performed a longitudinal analysis with participants of the English Longitudinal Study of Ageing. We included men and women with no NDs at baseline, aged 60 years and older, assessed every 2 years from 2004 to 2005 (wave2) to 2016-2017 (wave 8). The features were a set of 91 epidemiological and clinical baseline variables. The outcome was new events of Parkinson's, Alzheimer or dementia. After applying multiple imputations, we trained three DNN algorithms: Feedforward, TabTransformer, and Dense Convolutional (Densenet). In addition, we trained two algorithms based on Cox models: Elastic Net regularization (CoxEn) and selected features (CoxSf).

RESULTS

5433 participants were included in wave 2. During follow-up, 12.7% participants developed NDs. Although the five models predicted NDs events, the discriminative ability was superior using TabTransformer (Uno's C-statistic (coefficient (95% confidence intervals)) 0.757 (0.702, 0.805). TabTransformer showed superior time-dependent balanced accuracy (0.834 (0.779, 0.889)) and specificity (0.855 (0.0.773, 0.909)) than the other models. With the CoxSf (hazard ratio (95% confidence intervals)), age (10.0 (6.9, 14.7)), poor hearing (1.3 (1.1, 1.5)) and weight loss 1.3 (1.1, 1.6)) were associated with a higher DNN risk. In contrast, executive function (0.3 (0.2, 0.6)), memory (0, 0, 0.1)), increased gait speed (0.2, (0.1, 0.4)), vigorous physical activity (0.7, 0.6, 0.9)) and higher BMI (0.4 (0.2, 0.8)) were associated with a lower DNN risk.

CONCLUSION

TabTransformer is promising for prediction of NDs with heterogeneous tabular datasets with numerous features. Moreover, it can handle censored data. However, Cox models perform well and are easier to interpret than DNNs. Therefore, they are still a good choice for NDs.

Association between functional limitation and quality of life among older adults with multimorbidity in Luxembourg

Introduction

Multimorbidity, defined as the co-existence of two or more chronic conditions, is affecting an increasing number of Europeans, leading to poorer quality of life (QoL). This study assessed how functional limitation affects the QoL trajectories in a cohort of older individuals having multimorbidity, and whether there are any gender differences in these effects.

Methods

We used a longitudinal cohort of 906 multimorbid respondents 50 years of age or older from Luxembourg who participated in four waves of the Survey of Health, Ageing, and Retirement in Europe (2013-2020). We used the Control, Autonomy, Self-Realization, and Pleasure scale (CASP-12) to assess QoL and the Global Activity Limitation Indicator (GALI) to measure functional limitation. Multigroup latent growth curve (LGC) modeling techniques were employed to assess how the measures of functional limitation over time are related to QoL trajectories and whether or not these effects are different by sex.

Results

In 2013, over 60% of older residents of Luxembourg were affected by multimorbidity. The results from the LGC models suggest that both men and women with multimorbidity experienced a statistically significant decline in QoL between 2013 and 2020 at a constant rate; there were no significant differences in the rate of this change between men and women. The level of QoL at baseline and over time was significantly lower for individuals reporting functional limitation. However, functional limitation had no significant impact on the rate of decline in QoL for both men and women.

Discussion and conclusions

As an increasing number of individuals in Europe are becoming vulnerable to more years lived with multiple chronic conditions, there is a growing need to identify factors that may lead to improvements in QoL among people affected by multimorbidity. Gaining more knowledge on the role of functional limitation may be particularly important for planning comprehensive care for patients with multimorbidity.

How multimorbidity and socio-economic factors affect Long Covid: Evidence from European Countries

Introduction

An increasing number of individuals continue reporting symptoms following the acute stage of Covid-19 infection. Few studies have investigated the factors related to Long Covid. Our aim was to assess how multimorbidity, socio-economic factors (immigration, education, employment, and income), and country of residence affect the presence and number of persistent symptoms attributable to Covid-19 illness in Europe.

Methods

We used data from the SHARE Corona surveys collected in 2020 and 2021. The sample included 4,004 respondents aged 50 years and older who were affected by the Corona virus. The outcome was the number of persistent symptoms attributable to Covid-19 illness, including: fatigue; cough, congestion, shortness of breath; loss of taste or smell; headache; body aches, joint pain; chest or abdominal pain; diarrhoea, nausea; and confusion. We conducted a multilevel analysis for a hurdle model with negative binomial distribution.

Results

Overall, 73% of respondents were estimated to have at least one persistent symptom associated with Covid-19 illness and, on average, they had 2.73 symptoms. However, there were some statistically significant across country differences in the presence and number of symptoms. Respondents who were employed were more likely to report at least one symptom (OR = 1.40) and those with higher levels of education were less likely to report any symptoms (OR = 0.67). Respondents with multimorbidity had an increased risk of experiencing an additional symptom (RR = 1.12) while respondents who were employed had a decreased risk of experiencing an additional symptom (RR = 0.85).

Discussion and conclusions

Presence and number of persistent symptoms associated with Covid-19 illness was highly prevalent and varied significantly across European countries. Evidence from the present work underscores the need to target high-risk groups and those with multimorbidity to reduce long-term health consequences of Covid-19.

Investigating unmet need for healthcare using the European Health Interview Survey: a cross-sectional survey study of Luxembourg

OBJECTIVES

We investigate the prevalence of unmet need arising from wait times, distance/transportation and financial affordability using the European Health Interview Survey. We explore associations between individual characteristics and the probability of reporting unmet need.

DESIGN

Cross-sectional survey conducted between February and December 2014.

SETTING AND PARTICIPANTS

4004 members of the resident population in private households registered with the health insurance fund in Luxembourg aged 15 years and over.

OUTCOME MEASURES

Six binary variables that measured unmet need arising from wait time, distance/transportation and affordability of medical, dental and mental healthcare and prescribed medicines among those who reported a need for care.

RESULTS

The most common barrier to access arose from wait times (32%) and the least common from distance/transportation (4%). Dental care (12%) was most often reported as unaffordable, followed by prescribed medicines (6%), medical (5%) and mental health (5%) care. Respondents who reported bad/very bad health were associated with a higher risk of unmet need compared with those with good/very good health (wait: OR 2.41, 95% CI 1.53 to 3.80, distance/transportation: OR 7.12, 95% CI 2.91 to 17.44, afford medical care: OR 5.35, 95% CI 2.39 to 11.95, afford dental care: OR 3.26, 95% CI 1.86 to 5.71, afford prescribed medicines: OR 2.22, 95% CI 1.04 to 4.71, afford mental healthcare: OR 3.58, 95% CI 1.25 to 10.30). Income between the fourth and fifth quintiles was associated with a lower risk of unmet need for dental care (OR 0.29, 95% CI 0.16 to 0.53), prescribed medicines (OR 0.38, 95% CI 0.17 to 0.82) and mental healthcare (OR 0.17, 95% CI 0.05 to 0.61) compared with income between the first and second quintiles.

CONCLUSIONS

Recent and planned reforms to address waiting times and financial barriers to accessing healthcare may help to address unmet need. In addition, policy-makers should consider additional policies targeted at high-risk groups with poor health and low incomes.

Cervical Injury Outcomes among Older Adults Admitted to an Inpatient Trauma Service

OBJECTIVE

Older adults are an increasing proportion of patients admitted to trauma services. Trauma in older adults' results from many mechanisms of injury with the distribution of mechanisms of injury among older adults different than those of younger adults. The acute management of these injuries may determine the patients' ability to return to independent living. It is known that prolonged immobilization of older patients results in deterioration of their functional status and increases the likelihood of hospital acquired complications, notably pneumonia, delirium, and loss of ambulation.

DESIGN/SETTING

We reviewed 213 patients aged 65 and older admitted to our trauma services who sustained cervical spine injuries that were either placed in c spine immobilization or were not to understand the outcomes associated with their mechanism of injury.

RESULTS

The youngest patients (65-74 years) were proportionately more likely to have sustained high energy injuries associated with motor vehicle crashes (36%) with a mortality rate of 11.5%. The oldest age group (> 85 years) had a higher mortality rate from falls from standing injuries (31%). Patients discharged with a collar were more likely to return to independent living. In addition, 96% of the patients that died in the acute care setting were not in cervical collar immobilization.

CONCLUSION

Patients under 85 years with a cervical spine injury should be placed in c-spine immobilization and aggressively managed with a multidisciplinary team approach. The older adult trauma population requires specialty care including rapid cervical spine evaluation and prescreening of functional status on admission. The NEXUS guideline should be enhanced for the older adult trauma population.

Challenges of maintaining accountability in networks of health and care organisations: A study of developing Sustainability and Transformation Partnerships in the English National Health Service

The English National Health Service (NHS) constitutes a unique institutional context, which combines elements of hierarchy, markets and networks. This has always raised issues about competing forms of accountability. Recent policy has emphasised a move from quasi market competition towards collaboration in the form of new regional organisational arrangements known as Sustainability and Transformation Partnerships (STPs). We explore accountability relationships in STPs, focusing on the challenges of increasing horizontal accountability given existing vertical accountabilities, most notably to national regulators. We utilize a case study approach concentrated on three Clinical Commissioning Groups (CCGs) in urban and rural settings in England. We conducted in-person interviews with 22 managers from NHS organisations and local authorities and examined local documents to obtain information on governance and accountability structures. The fieldwork was undertaken between November 2017 and July 2018. We analysed results by considering which actors were accountable to what forums and the nature of the obligation (vertical or horizontal). We found that individual organisations still retained vertical accountabilities and were reluctant to be held accountable for the whole STP, given they were responsible for only part of the joint effort. Moreover, organisations did not feel accountable to STPs and instead highlighted vertical accountabilities upwards to their own boards and to national regulators; and downwards to the public. But while local commissioning organisations, CCGs engaged with their members and the public, STPs failed to engage adequately with the public. Nevertheless, there were indications that horizontal accountability was starting to develop. This could become complementary to vertical accountability by facilitating mutual learning and peer review to anticipate and defer regulatory intervention. While vertical accountability is necessary to provide oversight and apply sanctions, it is not sufficient and should be accompanied by horizontal accountability.

Examining the use of economic evaluations in health-related humanitarian programmes in low- and middle-income countries: a systematic review

The costly nature of health sector responses to humanitarian crises and resource constraints means that there is a need to identify methods for priority setting and long-term planning. One method is economic evaluation. The aim of this systematic review is to examine the use of economic evaluations in health-related humanitarian programmes in low- and middle-income countries. This review used peer-reviewed literature published between January 1980 and June 2018 extracted from four main electronic bibliographic databases. The eligibility criteria were full economic evaluations (which compare the costs and outcomes of at least two interventions and provide information on efficiency) of health-related services in humanitarian crises in low- and middle-countries. The quality of eligible studies is appraised using the modified 36-question Drummond checklist. From a total of 8127 total studies, 11 full economic evaluations were identified. All economic evaluations were cost-effectiveness analyses. Three of the 11 studies used a provider perspective, 2 studies used a healthcare system perspective, 3 studies used a societal perspective and 3 studies did not specify the perspective used. The lower quality studies failed to provide 7information on the unit of costs and did not justify the time horizon of costs and discount rates, or conduct a sensitivity analysis. There was limited geographic range of the studies, with 9 of the 11 studies conducted in Africa. Recommendations include greater use of economic evaluation methods and data to enhance the microeconomic understanding of health interventions in humanitarian settings to support greater efficiency and transparency and to strengthen capacity by recruiting economists and providing training in economic methods to humanitarian agencies.

The regulation of competition and procurement in the National Health Service 2015-2018: enduring hierarchical control and the limits of juridification

Since 1990, market mechanisms have occurred in the predominantly hierarchical National Health Service (NHS). The Health and Social Care Act 2012 led to concerns that market principles had been irrevocably embedded in the NHS and that the regulators would acquire unwarranted power compared with politicians (known as 'juridification'). To assess this concern, we analysed regulatory activity in the period from 2015 to 2018. We explored how economic regulation of the NHS had changed in light of the policy turn back to hierarchy in 2014 and the changes in the legislative framework under Public Contracts Regulations 2015. We found the continuing dominance of hierarchical modes of control was reflected in the relative dominance and behaviour of the sector economic regulator. But there had also been a limited degree of juridification involving the courts. Generally, the regulatory decisions were consistent with the 2014 policy shift away from market principles and with the enduring role of hierarchy in the NHS, but the existing legislative regime did allow the incursion of pro market regulatory decision making, and instances of such decisions were identified.

Agreeing the allocation of scarce resources in the English NHS: Ostrom, common pool resources and the role of the state

A challenge facing health systems such as the English National Health Service (NHS), which operate in a context of diversity of provision and scarcity of financial resources, is how organisations engaged in the provision of services can be encouraged to adopt collective resource utilisation strategies to ensure limited resources are utilised in the interests of service users and, in the case of tax funded services, the general public. In this paper the authors apply Elinor Ostrom's work concerning communities' self-governance of common pool resources to the development of collective approaches to the utilisation of resources for the provision of health services. Focusing on the establishment of Sustainability and Transformation Partnerships (STPs) in the English NHS, and drawing on interviews with senior managers in English NHS purchaser and provider organisations, we use Ostrom's work as a frame to analyse STPs, as vehicles to agree and enact shared rules governing the allocation of financial resources, and the role of the state in relation to the development of this collective governance. While there was an unwillingness to use STPs to agree collective rules for resource allocation, we found that local actors were discussing and agreeing collective approaches regarding how resources should be utilised to deliver health services in order to make best use of scarce resources. State influence on the development of collective approaches to resource allocation through the STP was viewed by some as coercive, but also provided a necessary function to ensure accountability. Our analysis suggests Ostrom's notion of resource 'appropriation' should be extended to capture the nuances of resource utilisation in complex production chains, such as those involved in the delivery of health services where the extraction of funds is not an end in itself, but where the value of resources depends on how they are utilised.

Measuring the Activity of Mental Health Services in England: Variation in Categorising Activity for Payment Purposes

In the context of international interest in reforming mental health payment systems, national policy in England has sought to move towards an episodic funding approach. Patients are categorised into care clusters, and providers will be paid for episodes of care for patients within each cluster. For the payment system to work, clusters need to be appropriately homogenous in terms of financial resource use. We examine variation in costs and activity within clusters and across health care providers. We find that the large variation between providers with respect to costs within clusters mean that a cluster-based episodic payment system would have substantially different financial impacts across providers.

Moving towards strategic commissioning: impact on clinical commissioning groups as membership organizations

Objective

This paper aims to explore the nature of clinical commissioning groups (CCGs) in England as membership organizations. Utilizing the concept of meta-organization as a lens, we discuss the impact that this organizational form might have on CCGs’ ability to become ‘strategic commissioners’.

Methods

We used a longitudinal qualitative approach to explore the adoption and implementation of primary care co-commissioning. The study was undertaken between May 2015 and June 2017 and included interviews with senior policy makers, analysis of policy documents, two telephone surveys, and case studies in four CCGs nationally.

Results

CCGs operate as membership organizations with closed boundary and low stratification, whereby a consensus or majority needs to be reached by members when activities impact on membership or the CCG’s constitution. While CCGs should move towards a more strategic commissioning role that is focused on local priorities agreed by their members, they are faced with a complex system of accountabilities and responsibilities, which makes this difficult to achieve.

Conclusions

The nature of CCGs as membership-based meta-organizations has the potential to both help and hinder CCGs in becoming strategic commissioners. The complexities in accountability and governance that the membership approach introduces, and the potential difficulties that CCGs face with competing meta-organizations, raises questions about the future of CCGs as membership organizations.

Achieving integrated care through commissioning of primary care services in the English NHS: a qualitative analysis

OBJECTIVES

Since April 2015, Clinical Commissioning Groups (CCGs) have taken on the responsibility to commission primary care services. The aim of this paper is to analyse how CCGs have responded to this new responsibility and to identify challenges and factors that facilitated or inhibited achievement of integrated care systems.

DESIGN

We undertook an exploratory approach, combining data from interviews and national telephone surveys, with analysis of policy documents and case studies in four CCGs. Data were analysed using thematic content analysis.

SETTING/PARTICIPANTS

We reviewed 147 CCG application documents and conducted two national telephone surveys with CCGs (n=49 and n=21). We interviewed 6 senior policymakers and 42 CCG staff who were involved in primary care co-commissioning (general practitioners and managers). We observed 74 primary care commissioning committee meetings and their subgroups (approx. 111 hours).

RESULTS

CCGs in our case studies focused their primary care commissioning activities on developing strategic plans, 'new' primary care initiatives, and dealing with legacy work. Many plans focused on incentivising and supporting practices to work together and provide a broad range of services. There was a clear focus on ensuring the sustainability of general practice. Our respondents expressed mixed views as to what new collaborative service models, such as the new models of care and sustainability and transformation partnerships (STPs), would mean for the future of primary care and the impact they could have on CCGs and their members.

CONCLUSIONS

There is a disconnect between locally based primary care and the wider system. One of the major challenges we identified is the lack of knowledge and expertise in the field of primary care at STP level. While primary care commissioning by CCGs seems to be supporting local collaborations between practices, there is some way to go before this is translated into broader integration initiatives across wider footprints.

Funding approaches for mental health services: Is there still a role for clustering?

Funding for mental health services in England faces many challenges including operating under financial constraints where it is not easy to demonstrate the link between activity and funding. Mental health services need to operate alongside and collaborate with acute hospital services where there is a well-established system for paying for activity. The funding landscape is shifting at a rapid pace and we outline the distinctions between the three main options - block contracts, episodic payment and capitation. Classification of treatment episodes via clustering presents an opportunity to demonstrate activity and reward it within these payment approaches. We have been engaged in research to assess how well the clustering system is performing against a number of fundamental criteria. Clusters need to be reliably recorded, to correspond to health needs, and to treatments that require roughly similar resources. We find that according to these criteria, clusters are falling short of providing a sound basis for measuring and financing services. Yet, we argue, it is the best available option and is essential for a more transparent funding approach for mental health to demonstrate its claim on resources, and that, as such, clusters should be a starting point for evolving a better funding system.

Uptake of mandatory outcome measures in mental health services

Aims and method

The collection of results of a specific outcome measure, the Health of the Nation Outcome Scales (HoNOS), is mandatory for mental healthcare providers in the National Health Service in England. Not all providers collect HoNOS data and coverage varies widely. This paper explores, by means of interviews with clinicians and policy makers and econometric analysis of HoNOS data, the barriers and incentives to the uptake of HoNOS and outcomes more generally, and the key characteristics associated with providers who do undertake HoNOS.

Results

The main barriers to the collection of outcomes involve a lack of adequate feedback mechanisms, a lack of perceived clinical relevance and poor information technology infrastructure. Econometric results show HoNOS collection is associated with providers who produce high-quality data.

Clinical implications

Initiatives should focus on putting systems in place to encourage feedback mechanisms for clinicians.

How are clinical commissioning groups managing conflicts of interest under primary care co-commissioning in England? A qualitative analysis

OBJECTIVES

From April 2015, NHS England (NHSE) started to devolve responsibility for commissioning primary care services to clinical commissioning groups (CCGs). The aim of this paper is to explore how CCGs are managing potential conflicts of interest associated with groups of GPs commissioning themselves or their practices to provide services.

DESIGN

We carried out two telephone surveys using a sample of CCGs. We also used a qualitative case study approach and collected data using interviews and meeting observations in four sites (CCGs).

SETTING/PARTICIPANTS

We conducted 57 telephone interviews and 42 face-to-face interviews with general practitioners (GPs) and CCG staff involved in primary care co-commissioning and observed 74 meetings of CCG committees responsible for primary care co-commissioning.

RESULTS

Conflicts of interest were seen as an inevitable consequence of CCGs commissioning primary care. Particular problems arose with obtaining unbiased clinical input for new incentive schemes and providing support to GP provider federations. Participants in meetings concerning primary care co-commissioning declared conflicts of interest at the outset of meetings. Different approaches were pursued regarding GPs involvement in subsequent discussions and decisions with inconsistency in the exclusion of GPs from meetings. CCG senior management felt confident that the new governance structures and policies dealt adequately with conflicts of interest, but we found these arrangements face limitations. While the revised NHSE statutory guidance on managing conflicts of interest (2016) was seen as an improvement on the original (2014), there still remained some confusion over various terms and concepts contained therein.

CONCLUSIONS

Devolving responsibility for primary care co-commissioning to CCGs created a structural conflict of interest. The NHSE statutory guidance should be refined and clarified so that CCGs can properly manage conflicts of interest. Non-clinician members of committees involved in commissioning primary care require training in order to make decisions requiring clinical input in the absence of GPs.

General practitioners' views of clinically led commissioning: cross-sectional survey in England

OBJECTIVES

Involving general practitioners (GPs) in the commissioning/purchasing of services has been an important element in English health policy for many years. The Health and Social Care Act 2012 handed responsibility for commissioning of the majority of care for local populations to GP-led Clinical Commissioning Groups (CCGs). In this paper, we explore GP attitudes to involvement in commissioning and future intentions for engagement.

DESIGN AND SETTING

Survey of a random sample of GPs across England in 2015.

METHOD

The Eighth National GP Worklife Survey was distributed to GPs in spring 2015. Responses were received from 2611 respondents (response rate = 46%). We compared responses across different GP characteristics and conducted two sample tests of proportions to identify statistically significant differences in responses across groups. We also used multivariate logistic regression to identify the characteristics associated with wanting a formal CCG role in the future.

RESULTS

While GPs generally agree that they can add value to aspects of commissioning, only a minority feel that this is an important part of their role. Many current leaders intend to quit in the next 5 years, and there is limited appetite among those not currently in a formal role to take up such a role in the future. CCGs were set up as 'membership organisations' but only a minority of respondents reported feeling that they had 'ownership' of their local CCG and these were often GPs with formal CCG roles. However, respondents generally agree that the CCG has a legitimate role in influencing the work that they do.

CONCLUSION

CCGs need to engage in active succession planning to find the next generation of GP leaders. GPs believe that CCGs have a legitimate role in influencing their work, suggesting that there may be scope for CCGs to involve GPs more fully in roles short of formal leadership.

Costs and Performance of English Mental Health Providers

BACKGROUND

Despite limited resources in mental health care, there is little research exploring variations in cost performance across mental health care providers. In England, a prospective payment system for mental health care based on patient needs has been introduced with the potential to incentivise providers to control costs. The units of payment under the new system are 21 care clusters. Patients are allocated to a cluster by clinicians, and each cluster has a maximum review period.

AIMS OF THE STUDY

The aim of this research is to explain variations in cluster costs between mental health providers using observable patient demographic, need, social and treatment variables. We also investigate if provider-level variables explain differences in costs. The residual variation in cluster costs is compared across providers to provide insights into which providers may gain or lose under the new financial regime.

METHODS

The main data source is the Mental Health Minimum Data Set (MHMDS) for England for the years 2011/12 and 2012/13. Our unit of observation is the period of time spent in a care cluster and costs associated with the cluster review period are calculated from NHS Reference Cost data. Costs are modelled using multi-level log-linear and generalised linear models. The residual variation in costs at the provider level is quantified using Empirical Bayes estimates and comparative standard errors used to rank and compare providers.

RESULTS

There are wide variations in costs across providers. We find that variables associated with higher costs include older age, black ethnicity, admission under the Mental Health Act, and higher need as reflected in the care clusters. Provider type, size, occupancy and the proportion of formal admissions at the provider-level are also found to be significantly associated with costs. After controlling for patient- and provider-level variables, significant residual variation in costs remains at the provider level.

DISCUSSION AND LIMITATIONS

The results suggest that some providers may have to increase efficiency in order to remain financially viable if providers are paid national fixed prices (tariffs) under the new payment system. Although the classification system for payment is not based on diagnosis, a limitation of the study is the inability to explore the effect of diagnosis due to poor coding in the MHMDS.

IMPLICATIONS FOR HEALTH CARE PROVISION AND USE

We find that some mental health care providers in England are associated with higher costs of provision after controlling for characteristics of service users and providers. These higher costs may be associated with higher quality care or with inefficient provision of care.

IMPLICATIONS FOR HEALTH POLICIES

The introduction of a national tariff is likely to provide a strong incentive to reduce costs. Policies may need to consider safe-guarding local health economies if some providers make substantial losses under the new payment regime.

IMPLICATIONS FOR FURTHER RESEARCH

Future research should consider the relationship between costs and quality to ascertain whether reducing costs may potentially negatively impact patient outcomes.

Variations in Performance of Mental Health Providers in the English NHS: An Analysis of the Relationship Between Readmission Rates and Length-of-Stay

Length-of-stay (LOS) for inpatient mental health care is a major driver of variation in resource use internationally. We explore determinants of LOS in England, focusing on the impact of emergency readmission rates which can serve as a measure of the quality of care. Data for 2009/2010 and 2010/2011 are analysed using hierarchical and non-hierarchical models. Unexplained residual variation among providers is quantified using Empirical Bayes techniques. Diagnostic, treatment and patient-level demographic variables are key drivers of LOS. Higher emergency readmission rates are associated with shorter LOS. Ranking providers by residual variation reveals significant differences, suggesting some providers can improve performance.

Comparing the performance of English mental health providers in achieving patient outcomes

Evidence on provider payment systems that incorporate patient outcomes is limited for mental health care. In England, funding for mental health care services is changing to a prospective payment system with a future objective of linking some part of provider payment to outcomes. This research examines performance of mental health providers offering hospital and community services, in order to investigate if some are delivering better outcomes. Outcomes are measured using the Health of the Nation Outcome Scales (HoNOS) - a clinician-rated routine outcome measure (CROM) mandated for national use. We use data from the Mental Health Minimum Data Set (MHMDS) - a dataset on specialist mental health care with national coverage - for the years 2011/12 and 2012/13 with a final estimation sample of 305,960 observations with follow-up HoNOS scores. A hierarchical ordered probit model is used and outcomes are risk adjusted with independent variables reflecting demographic, need, severity and social indicators. A hierarchical linear model is also estimated with the follow-up total HoNOS score as the dependent variable and the baseline total HoNOS score included as a risk-adjuster. Provider performance is captured by a random effect that is quantified using Empirical Bayes methods. We find that worse outcomes are associated with severity and better outcomes with older age and social support. After adjusting outcomes for various risk factors, variations in performance are still evident across providers. This suggests that if the intention to link some element of provider payment to outcomes becomes a reality, some providers may gain financially whilst others may lose. The paper contributes to the limited literature on risk adjustment of outcomes and performance assessment of providers in mental health in the context of prospective activity-based payment systems.

An international comparison of efficiency of inpatient mental health care systems

There is a fundamental gap in the evidence base on quantitative cross-country comparison of mental healthcare systems due to the challenges of comparative analysis in mental health including a paucity of good quality data. We explore whether existing limited data sources can potentially be exploited to examine technical efficiency of inpatient mental healthcare systems in 32 OECD countries in 2010. We use two analytical approaches: Data Envelopment Analysis (DEA) with bootstrapping to produce confidence intervals of efficiency scores and country rankings, and Cluster Analysis to group countries according to two broad efficiency groupings. We incorporate environmental variables using a two-stage truncated regression. We find slightly tighter confidence intervals for the less efficient countries which loosely corresponds with the 'inefficient' cluster grouping in the Cluster Analysis. However there is little stability in country rankings making it difficult with current data to draw any policy inferences. Environmental factors do not appear to significantly impact on efficiency scores. The most pressing pursuit remains the search for better national data in mental healthcare to underpin future analyses. Otherwise the use of any sophisticated analytic techniques will prove futile for establishing robust conclusions regarding international comparisons of the performance of mental healthcare systems.

Protecting pro-poor health services during financial crises: lessons from experience

OBJECTIVE

This chapter assesses the extent to which previous economic and financial crises had a negative impact on health outcomes and health financing. In addition, we review evidence related to the effectiveness of different policy measures undertaken in past crises to protect access to health services, especially for the poor and vulnerable. The current global crisis is unique both in terms of its scale and origins. Unlike most previous instances, the current crisis has its origins in developed countries, initially the United States, before it spread to middle- and lower-income countries. The current crisis is now affecting almost all countries at all levels of income. This chapter addresses several key questions aimed at helping inform possible policy responses to the current crisis from the perspective of the health sector: What is the nature of the current crisis and in what ways does it differ from previous experiences? What are some of the key. lessons from previous crises? How have governments responded previously to protect health from such macroeconomic shocks? How can we improve the likelihood of positive action today?

METHODOLOGY/APPROACH

The chapter reviews the literature on the impact of financial crises on health outcomes and health expenditures and on the effectiveness of past policy efforts to protect human development during periods of economic downturn. It also presents analysis of household surveys and health expenditure data to track health seeking behavior and out-of-pocket expenditures by households during times of financial crisis.

FINDINGS

Evidence from previous crises indicates that health-related impacts during economic downturns can occur through various channels. The impact in households experiencing reductions in employment and income could be manifest in terms of poorer nutritional outcomes and lower levels of utilization of health care when needed. Households may become impoverished, reduce needed health services, and experience reductions in consumption as a result of health shocks occurring during a time when their economic vulnerability has increased. Women, children, the poor, and informal sector workers are likely to be most at risk of experiencing negative health-related consequences in a crisis. Real government spending per capita on health care could decline due to reduced revenues, currency devaluations, and potential reductions in external aid flows. Low-income countries with weak fiscal positions are likely to be the most vulnerable.

IMPLICATIONS FOR POLICY

Past crises can inform policy-making aimed at protecting health outcomes and reducing financial risk from health shocks. Evidence from previous crises indicates that broad-brush strategies that maintained overall levels of government health spending tended not to be successful, failing to protect access to quality health services especially for the poor. It is particularly vital to ensure access to essential health commodities, which in many low-income countries are imported, in the face of weakening exchange rates. Focused efforts to sustain the supply of lower-level basic services, combined with targeted demand-side approaches like conditional cash transfers may be more effective than broader sectoral approaches. Low-income countries may need specific short-term measures to ensure that health outcomes do not suffer.

Characterization of TH1 and CTSZ, two non-imprinted genes downstream of GNAS1 in chromosome 20q13

The clustering and coordinate regulation of many imprinted genes justifies positional searches for imprinted genes adjacent to known ones. We recently characterized a locus on 20q13, containing GNAS1, which has a highly complex imprinted expression pattern. In a search for neighbouring genes, we have now characterized a new gene, TH1, downstream of GNAS1. TH1 and GNAS1 are separated by more than 70 kb consisting largely of interspersed repetitive DNA. TH1 is the homologue of a gene that, in Drosophila, lies adjacent to the DNA repair gene mei-41. We have determined the full-length structures of human, mouse and Drosophila TH1. Though of unknown function, TH1 is highly conserved and widely expressed. Nonetheless, there is no similar Caenorhabditis elegans protein. We have also determined the complete genomic structures of human and Drosophila TH1. The Drosophila gene has five exons spanning 2.6 kb. The last three introns have precise equivalents in the human gene, which has 15 exons spanning 14 kb and is transcribed away from GNAS1. Using a single-nucleotide polymorphism in the 3' untranslated region, we have demonstrated biallelic TH1 expression in human fetal tissues, suggesting that, unlike GNAS1, TH1 is probably not imprinted. Immediately downstream of TH1 lies CTSZ, encoding the recently described cysteine protease, cathepsin Z. We have also elucidated the genomic structure of this gene; it has six exons spanning 12 kb and is oriented tail-to-tail with TH1, only 70 bp separating their polyadenylation sites. A polymorphism was again identified within the CTSZ 3' untranslated region and used to demonstrate biallelic expression in fetal tissues.

Bidirectional imprinting of a single gene: GNAS1 encodes maternally, paternally, and biallelically derived proteins

The GNAS1 gene encodes the alpha subunit of the guanine nucleotide-binding protein Gs, which couples signaling through peptide hormone receptors to cAMP generation. GNAS1 mutations underlie the hormone resistance syndrome pseudohypoparathyroidism type Ia (PHP-Ia), so the maternal inheritance displayed by PHP-Ia has raised suspicions that GNAS1 is imprinted. Despite this suggestion, in most tissues Gsalpha is biallelically encoded. In contrast, the large G protein XLalphas, also encoded by GNAS1, is paternally derived. Because the inheritance of PHP-Ia predicts the existence of maternally, rather than paternally, expressed transcripts, we have investigated the allelic origin of other mRNAs derived from GNAS1. We find this gene to be remarkable in the complexity of its allele-specific regulation. Two upstream promoters, each associated with a large coding exon, lie only 11 kb apart, yet show opposite patterns of allele-specific methylation and monoallelic transcription. The more 5' of these exons encodes the neuroendocrine secretory protein NESP55, which is expressed exclusively from the maternal allele. The NESP55 exon is 11 kb 5' to the paternally expressed XLalphas exon. The transcripts from these two promoters both splice onto GNAS1 exon 2, yet share no coding sequences. Despite their structural unrelatedness, the encoded proteins, of opposite allelic origin, both have been implicated in regulated secretion in neuroendocrine tissues. Remarkably, maternally (NESP55), paternally (XLalphas), and biallelically (Gsalpha) derived proteins all are produced by different patterns of promoter use and alternative splicing of GNAS1, a gene showing simultaneous imprinting in both the paternal and maternal directions.

The human GNAS1 gene is imprinted and encodes distinct paternally and biallelically expressed G proteins

The GNAS1 gene encodes the alpha subunit of the G protein Gs, which couples receptor binding by several hormones to activation of adenylate cyclase. Null mutations of GNAS1 cause pseudohypoparathyroidism (PHP) type Ia, in which hormone resistance occurs in association with a characteristic osteodystrophy. The observation that PHP Ia almost always is inherited maternally has led to the suggestion that GNAS1 may be an imprinted gene. Here, we show that, although Gsalpha expression (directed by the promoter upstream of exon 1) is biallelic, GNAS1 is indeed imprinted in a promoter-specific fashion. We used parthenogenetic lymphocyte DNA to screen by restriction landmark genomic scanning for loci showing differential methylation between paternal and maternal alleles. This screen identified a region that was found to be methylated exclusively on a maternal allele and was located approximately 35 kb upstream of GNAS1 exon 1. This region contains three novel exons that are spliced into alternative GNAS1 mRNA species, including one exon that encodes the human homologue of the large G protein XLalphas. Transcription of these novel mRNAs is exclusively from the paternal allele in all tissues examined. The differential imprinting of separate protein products of GNAS1 therefore may contribute to the anomalous inheritance of PHP Ia.

[Tomographic study of the intra-abdominal digestive tract. Contributions of percutaneous echography and scanner in daily practice]

Endoscopy and radiological imaging are complementary. However the gastro-intestinal tract is routinely being imaged in CT and ultrasound, often performed for other indications. When an abnormality is discovered, several questions have to be addressed. Is the lesion due to a bowel abnormality? When bowel wall thickening is present, is it due to poor opacification or is it due to inflammation or tumor? Circumferential symmetrical thickening is more in favor of an inflammatory lesion, while focal asymmetrical thickening is more in favor of a neoplastic lesion. Inflammatory and lymphomatous lesion can have similar appearances. Guidelines to aid in diagnostic interpretation of gastrointestinal lesions are discussed, including features of appendicitis and obstruction.

Preceptor program evaluation demonstrates improved orientation

Although the preceptor method of orientation is generally accepted as an effective mechanism for orienting newly employed nurses, very few evaluation studies of preceptor programs have been reported in the literature. This article describes a study designed prior to implementing a preceptor program at the University of Wisconsin Hospital and Clinics in order to measure the outcomes of the program. Data were collected on the satisfaction of orientees, preceptors, other staff nurses, and nurse managers. The preceptor role and preceptor's level of comfort and skill were studied. To quantify the economic impact, both length of orientation and nursing turnover were considered.

Acute fatty liver of pregnancy: CT evaluation. Case report

CT scans of two patients with acute fatty liver of pregnancy were reviewed in conjunction with the clinical evolution of this uncommon and potentially fatal disorder. In each of the CT scans, liver density measurements were less than those of the spleen. While the findings are non-specific, in the proper clinical context they are highly suggestive and may be the sole method of diagnosis, as these patients often have coagulation problems which rule out liver biopsy. It is an important diagnosis, as the high maternal and fetal mortality rates appear to be considerably reduced by early foetal delivery.

[Acute fatty liver of pregnancy. Apropos of 4 cases: contribution of x-ray computed tomography]

Acute fatty liver of pregnancy is a disease of the third trimester, generally considered to be rare and to have a grave prognosis. Histologically the characteristic fine droplet steatosis usually produces distinct vacuolization. Successful treatment depends on accurate diagnosis and early delivery. Computed tomography is of value in the diagnosis of fatty liver through liver and spleen attenuation value measurements. We reviewed 4 cases of acute fatty liver of pregnancy. Computed tomography was performed in two cases and was very helpful in the diagnosis of this condition.

Giant cell astrocytoma in tuberous sclerosis: computed tomographic findings

Clinical presentation and computed tomography (CT) findings in four tuberous sclerosis patients with large ventricular tumours situated near the foramina of Monro, and causing obstructive hydrocephalus are described. These tumours (so-called giant cell astrocytomas) demonstrated uniform post-contrast enhancement. This finding, along with their location, distinguished them from the much commoner cortical and subependymal tubers of tuberous sclerosis.

Complete non-traumatic intravasation of myelographic contrast medium

Two cases are reported of complete non-traumatic intravasation of contrast medium during myelography, where repeat myelography was uneventful. These findings support the suggestion that inadvertent trauma leads to apparently non-traumatic intravasation.
