Towards a value-based commissioning of integrated mental health services
Background: Over the years, several reforms and initiatives have been introduced in England to improve the local healthcare commissioning process in the NHS. Recently, on April 28, 2022, the Health and Care Bill received Royal Assent and became an Act of the UK Parliament. The Act abolished Clinical Commissioning Groups (CCGs) and replaced them with forty-two Integrated Care Systems (ICSs), each of which has an Integrated Care Board (ICB) that as…
A protocol for mobilising novel finance models for collaborative health promotion and disease prevention initiatives
Background: The prevalence of preventable non-communicable disease (NCD) underpins the need for a life-course and cross-sectoral approach to population health that is grounded in health promotion and disease prevention. European Union (EU) countries typically spend 6 to 13% of gross domestic product (GDP) on health care, yet less than 3% of this is dedicated to prevention. The extent to which spending in other sectors prevents avoidable ill-healt…
Assessing the relationship between coverage of essential health services and poverty levels in low- and middle-income countries
Universal health coverage (UHC) aims to provide essential health services and financial protection to all. This study aimed to assess the relationship between the service coverage aspect of universal health coverage and poverty in low- and middle-income countries (LMICs). Using country-level data from 96 LMICs from 1990 to 2017, we employed fixed-effects and random-effects regressions to investigate the association of eight service coverage indic…
The impact of a new approach to family safeguarding in social care
Child safeguarding services intervene when a child is at risk of serious emotional or physical harm. Oxfordshire County Council is implementing a new approach to child safeguarding (Family Solutions Plus [FSP]) with a greater focus on whole family support and reducing the need for foster care. We sampled two cohorts of children closed within 1 year and examined the time spent in services. The sample included 474 children entering services before …
Predictors of positive outcomes from ‘Early Intervention in Psychosis’
This study aims to provide valuable insights into the long-term effects of variations in EIP service delivery. The study involves a large, diverse cohort including individuals treated by every EIP service in England. While there are limitations inherent in the observational nature of the study, any associations identified will be of great relevance to clinicians, researchers, and policymakers seeking to optimize EIP care. The results will enable …
Commissioning [Integrated] Care in England
Background: The emergence of Integrated Care Systems (ICSs) across England poses an additional challenge and responsibility for local commissioners to accelerate the implementation of integrated care programmes and improve the overall efficiency across the system. To do this, ICS healthcare commissioners could learn from the experience of the former local commissioning structures and identify areas of improvement in the commissioning process. Aim…
A rationing framework for Integrated Care Systems
Background: Over the last 20 years, the NHS has introduced multiple changes in the commissioning structures, aiming at promoting integrated care in England. The Health and Care Bill 2021 is the latest and farthest-reaching reform, under which local commissioners from the emerging Integrated Care System (ICSs) are expected to accelerate the implementation of ‘integrated care programmes’. This overhaul demands local commissioners to develop approac…
Survival and community care use by care home residents in England
The aim was to provide evidence of mortality and community care costs of people living in care homes and to investigate its association with mental health based on the Mental Health Clustering Tool (MHCT). In an observational study, 5,782 residents living in 104 care homes were followed from 2014 to 2016. Residents were categorised into four groups using the MCHT: three with mental health conditions, ‘non-psychotic’, ‘psychotic’ or ‘organic’; and…
Heterogeneity in preferences for outcomes of integrated care for persons with multiple chronic diseases
This study has highlighted the heterogeneity in views of stakeholders in integrated care on what is important in health(care) for persons with multi-morbidity. To accurately value integrated care a variety of outcomes beyond health-e.g., enjoyment of life and experience with care-should be taken into account

Bundled payments for chronic diseases increased health care expenditure in the Netherlands, especially for multimorbid patients
Bundled payments aim to stimulate the integration of healthcare services and ultimately reduce healthcare expenditure growth through improved quality of care. The Netherlands introduced bundled payments for chronic diseases in 2010 by reimbursing providers annually for a bundle of primary care services related to COPD, Diabetes, or Vascular Risk Management. We aimed to assess the long-term effects of these bundled payments on healthcare expenditu…
Methodological Quality of Economic Evaluations in Integrated Care
The Selfie framework for integrated care for multi-morbidity
BACKGROUND: The rise of multi-morbidity constitutes a serious challenge in health and social care organisation that requires a shift from disease- towards person-centred integrated care. The aim of the current study was to develop a conceptual framework that can aid the development, implementation, description, and evaluation of integrated care programmes for multi-morbidity. METHODS: A scoping review and expert discussions were used to identify …

Evaluating the cost-effectiveness of population health interventions alongside literature reviews
Introduction: Decision-makers are interested in the cost-effectiveness of population health interventions but there is often lack of (robust) evidence from empirical economic evaluations. Thus, data synthesis and decision-modelling are frequently used by health economists to inform evidence-based decision-making. However, most literature reviews of evaluation studies are not designed to support an economic evaluation.Aim: We sought to develop a m…
Preliminary findings from the BRIghTER Dawn integrated care home support service programme
Introduction: A high proportion of people living in care homes have dementia, mental illness and/or physical frailty. An Integrated Care Home Support Service (CHSS) combined two evidence based approaches to deliver a stepped care and treatment to meet both physical and mental health needs, called the BRIghTER DAWN programme. These evidenced based approaches trained staff to deliver Dementia Assessment of Wellbeing and Needs (DAWN) and/or a person…

Financial Incentives to Stimulate Integration of Care
Introduction Chronic conditions are related to 60% of disability adjusted life years and account for 75% of total health care expenditure worldwide. The economic burden of chronic conditions is much larger when considering the costs of productivity loss and informal care. The threat that chronic conditions pose to population health and economies increase because of increasing prevalence and multi-morbidity, which multiplies the burden of chronic …

The cost-effectiveness of early care by dedicated teams for chronic mental health conditions
Introduction: Psychosis is a common and severe mental illness, with a large health and economic impact on societies worldwide. The earlier the illness is treated the better the long term outcomes. In England, Early Intervention in Psychosis (EIP) services have been introduced over the last 15 years to address this problem and they are included in the new Access and Waiting time standard in England published in April 2015. This standard mandates t…
Performing Economic Evaluation of Integrated Care
Health economists are increasingly interested in integrated care in order to support decision-makers to find cost-effective solutions able to tackle the threat that chronic diseases pose on population health and health and social care budgets. However, economic evaluation in integrated care is still in its early years, facing several difficulties. The aim of this paper is to describe the unique nature of integrated care as a topic for economic ev…

Bridging knowledge to develop an action plan for integrated care for chronic diseases in Greece
The health, social and economic impact of chronic diseases is well documented in Europe. However, chronic diseases threaten relatively more the 'memorandum and peripheral' Eurozone countries (i.e., Greece, Spain, Portugal and Ireland), which were under heavy recession after the economic crisis in 2009. Especially in Greece, where the crisis was the most severe across Europe, the austerity measures affected mainly people with chronic diseases. As …
The management of cardiovascular disease in the Netherlands
Developing and implementing cardiovascular disease management programmes is time-consuming and challenging. Multidisciplinary, patient-centred care demands multifaceted changes in routine care. As care pathways become more complex, they also become more expensive. Better preparedness and training can prevent unnecessary delays during the implementation period and are crucial to reducing costs

Assessing implementation variations of a disease management program in daily practice
The implementation of a disease management (DM) program in primary care is expected to vary across general practices. This variation may be caused by differences in "adjusting" the DM interventions to fit the context of each general practice and by practice-specific barriers and facilitators influencing the implementation. These causes of variability in implementing a DM program are important to understand the conditions for a successful implemen…
Evidence-based policy making
Background: In the Netherlands, a recently established regulation introduced a bundled payment system to promote disease management programs (DMPs) for patients with diabetes mellitus type two (DM), chronic obstructive pulmonary disorder (COPD) or at risk for a cardiovascular disease (CVR). Although, the wide-scale implementation of DM-DMPs was smooth and successful, the uptake of DMPs for COPD and CVR is still troublesome. This is because health…
Payment and economic evaluation of integrated care
Chronic diseases have an increasingly negative impact on (1) population health by increasing morbidity and mortality, (2) society by increasing health inequalities and burden to informal caregivers, and (3) economy by requiring enormous financial resources and jeopardising macro-economic development (e.g. consumption, capital accumulation, labour productivity and labour supply). Integrated care is the most promising concept in redesigning care to…
