To examine the evolution of health care integration strategies and associated conceptualization and practice through a review and synthesis of over 25 years of international academic research and literature.

A search of the health sciences literature was conducted using PubMed and EMBASE. A total of 114 articles were identified for inclusion and thematically analyzed using a strategy content model for systems-level integration.

Six major, inter-related shifts in integration strategies were identified: (1) from a focus on horizontal integration to an emphasis on vertical integration; (2) from acute care and institution-centered models of integration to a broader focus on community-based health and social services; (3) from economic arguments for integration to an emphasis on improving quality of care and creating value; (4) from evaluations of integration using an organizational perspective to an emerging interest in patient-centered measures; (5) from a focus on modifying organizational and environmental structures to an emphasis on changing ways of working and influencing underlying cultural attitudes and norms; and (6) from integration for all patients within defined regions to a strategic focus on integrating care for specific populations. We propose that underlying many of these shifts is a growing recognition of the value of understanding health care delivery and integration as processes situated in Complex-Adaptive Systems (CAS).

This review builds a descriptive framework against which to assess, compare, and track integration strategies over time.

Individuals suffering from serious mental illness (SMI) face many challenges of navigating a complex and often fragmented health care system and may die significantly earlier from co-morbid physical health conditions. Integrating mental and physical health care for individuals with SMI is an emerging trend addressing the often-neglected physical health care needs of this population to better coordinate care and improve health outcomes.

Population Health Management (PHM) provides a useful framework for designing integrated care programs for individuals with SMI.

This paper examines the structure and evolution of the integrated care program in Missouri in the context of PHM, highlighting particular elements of PHM that facilitate and support development of an integrated mental and physical health care program.

As health care reform provides external motivation to provide integrated care, this study can be useful as other states attempt to address this important issue.

Integrated health care delivery (IHCD), as a major issue of managed care, was considered the panacea to rising health care costs. In theory it would simultaneously provide high-quality and continuous care. However, owing to the backlash of managed care at the turn of the century many health care providers today refrain from using further integrative activities. Based on transaction cost economics, this chapter investigates why IHCD is deemed appropriate in certain circumstances and why it failed in the past. It explores the new understanding of IHCD, which focuses on actual integration through virtual integration instead of aggregation of health care entities. Current success factors of virtually integrated hybrid structures, which have been evaluated in a long-term case study conducted in the San Francisco Bay Area from July 2001 to September 2002, will elucidate the further development of IHCD and the implications for other industrialized countries, such as Germany.

Integration between primary and secondary healthcare services and institutions has been at the core of health policy in Scandinavian countries over the last decade. This paper is based on an explorative case study of recent reforms in the healthcare sector and their outcomes in Denmark, Norway and Sweden. We discuss the possibilities of and problems for integrating the healthcare sector through the coordination mechanisms of hierarchy, market and network. The paper also discusses whether the institutional logic of the healthcare field is moving from a dual logic of ‘cure’ and ‘care’ towards a unifying logic of ‘integrated care’. We find that although the organisational principles that regulate the relationship between actors in the healthcare field in the three countries have changed, the challenge of achieving a mix of coordinative mechanisms that promote, rather than weaken, integration remains. However, the new organisational and regulative arrangements are an arena for increased interaction and collaboration between the actors, and thus a foundation for change towards the institutional logic of integrated health care.

Researchers recommend a reorganization of the medical profession into larger groups with a multispecialty mix. We analyze whether there is evidence for the superiority of these models and if this organizational transformation is underway.

We summarize the evidence on scale and scope economies in physician group practice, and then review the trends in physician group size and specialty mix to conduct survivorship tests of the most efficient models.

The distribution of physician groups exhibits two interesting tails. In the lower tail, a large percentage of physicians continue to practice in small, physician-owned practices. In the upper tail, there is a small but rapidly growing percentage of large groups that have been organized primarily by non-physician owners.

While our analysis includes no original data, it does collate all known surveys of physician practice characteristics and group practice formation to provide a consistent picture of physician organization.

Our review suggests that scale and scope economies in physician practice are limited. This may explain why most physicians have retained their small practices.

Larger, multispecialty groups have been primarily organized by non-physician owners in vertically integrated arrangements. There is little evidence supporting the efficiencies of such models and some concern they may pose anticompetitive threats.

This is the first comprehensive review of the scale and scope economies of physician practice in nearly two decades. The research results do not appear to have changed much; nor has much changed in physician practice organization.

Purpose – This chapter explores the use of adaptive and disruptive change strategies to create an integrated health care delivery system that is both economically sustainable and patient-centered.

Design/methodology – This case study of Montefiore Medical Center is based on a year of research that included focus-group interviews; individual interviews with executives, frontline staff, and union leaders; site visits; analysis of internal data; and a literature review.

Findings – Montefiore Medical Center is using both adaptive and disruptive strategies to develop an integrated delivery system driven by capitated payments from health insurance companies, a focus on primary care and chronic disease management programs, and community outreach. The growth of these delivery system components in conjunction with Montefiore's Care Management Corporation (to help manage the health plan contracts) has contributed to an affordable cost of care, improved clinical outcomes, and proactive patient and community engagement.

Originality and value – There is a paucity of case studies describing how safety-net hospitals – and health systems in general – can integrate the services they provide to create a positive, seamless, and economical patient experience. The story of Montefiore Medical Center offers an overview of how health care infrastructure and payment methods can be transformed to align financial and clinical incentives and to better serve a patient population that largely depends on government health insurance.

Purpose: This chapter examines the implementation of lesbian, gay, bisexual, transgender, and queer (LGBTQ) health curricula in medical education, focusing on how this content is presented to students to understand if these curricula can fulfill goals of achieving healthcare equity for LGBTQ populations.

Methodology: This research draws on data from six months of participant observation of an academic medical center and school and 28 interviews with medical faculty, students, community members, administrators, and LGBTQ Health Center employees.

Findings: This research has three findings: (1) this medical school has variable definitions for LGBTQ health, making it a hybrid form of knowledge based in (a) understanding the unique health needs of; (b) being culturally competent to; and (c) being a (structural) advocate for LGBTQ patients; (2) LGBTQ health is integrated into multiple courses in the curriculum; and (3) LGBTQ health is becoming a medical specialty frequently delivered to students by LGBTQ health experts.

Research limitations and implications: This research used snowball sampling to recruit participants engaged in LGBTQ health at the institution; it therefore risks self-selection bias. Findings from this study are not generalizable.

Originality: This research argues that LGBTQ health experts engage in a new kind of diversity and inclusion work because (1) these health experts are not always LGBTQ identified; (2) this work is not necessarily unpaid or involuntary; and (3) it involves a hybrid knowledge requiring an understanding of LGBTQ identity, medical knowledge, and social science. Because these LGBTQ health experts opt into this work, and broadly define it, a message available to other physicians and students is that LGBTQ health remains elective.

Objective – Tanzania, Mexico, and the United States are at vastly different points on the economic development scale. Yet, their health systems can be classified as “developing”: they do not live up to their potential, considering the resources available to them. The three, representing many others, share a common structural deficiency: a segregated health care system that cannot achieve its basic goals, the optimal health of its people, and their possible satisfaction with the system. Segregation follows and signifies first and foremost the lack of financial integration in the system that prevents it from serving its goals through the objectives of equity, cost containment and sustainability, efficient production of care and health, and choice.

Method – The chapter contrasts the nature of the developing health care system with the common goals, objectives, and principles of the Emerging Paradigm (EP) in developed, integrated – yet decentralized –systems. In this context, the developing health care system is defined by its structural deficiencies, and reform proposals are outlined.

Findings – In spite of the vast differences amongst the three countries, their health care systems share strikingly similar features. At least 50% of their total funding sources are private. The systems comprise exclusive vertically integrated, yet segregated, “silos” that handle all systemic functions. These reflect and promote wide variations in health insurance coverage and levels of benefits – substantial portions of their populations are without adequate coverage altogether; a considerable lack of income protection from medical spending; an inability to formalize and follow a coherent health policy; a lack of financial discipline that threatens sustainability and overall efficiency; inefficient production of care and health; and an dissatisfied population. These features are often promoted by the state, using tax money, and donors.

Policy implications – The situation can be rectified by (a) “centralizing” – at any level of development and resource availability – health system finance around a set package of core medical benefits that is made available to the entire population and (b) “decentralizing” consumption and provision of care. The first serves equity and cost containment and sustainability. The second supports efficiency and client satisfaction.

Originality/value of chapter – The chapter views commonly discussed problems of the health care system – a lack of insurance coverage and income protection – as symptoms of a large problem: health system segregation.
