BackgroundA growing number of EU citizens suffers from diabetes, posing an emerging health, social and economic burden in the EU [1]. This burden is mostly driven by type 2 diabetes mellitus (T2DM), which is increasingly diagnosed at younger age and leads to a rising number of adults with T2DM aged 65 and older [1]. Due to these rising numbers in diabetes prevalence a growing number of patients faces accompanying comorbidities as well as complex needs [2][3][4][5]. However, many care systems are historically built on separate sectors (health vs. social care, in-vs. outpatient care). This traditional acute and episodic focus of care is inadequate to effectively meet the complex needs of patients as it increases the risk of care fragmentation and loss of information [6,7]. Although these circumstances are repetitively part of health policy initiatives [8,9], there is still an institutional and regulatory separation between health and social care services, as well as between ambulatory and inpatient care [10].Integrated care is said to improve outcomes of care by linking services of providers along the continuum of care and thus overcoming issues of fragmentation [11]. Back in 1996, Ed Wagner developed the Chronic Care Model (CCM), which became a cornerstone to improve care delivery for chronically ill patients. The CCM comprises the following six components: (1) community, (2) health system, (3) self-management support, (4) delivery system design, (5) decision support and (6) clinical information systems [12]. Ever since, different initiatives developed new models targeting specific weaknesses of the initial CCM.However, recent analysis uncovered that the understanding of established models' impact on chronic disease management is limited [13]. This is especially true for the effectiveness and applicability of chronic care models in different populations and settings [13]. Additionally, on behalf of the MANAGE CARE Study Group Background: Most current care models are disease-or symptom-focused and mostly do not account for the individual needs of patients with chronic diseases. The aim of this study was to develop an innovative, evidence-based and expert-based practice model for the management of patients with type 2 diabetes mellitus. Method: An iterative approach was used combining systematic literature search with qualitative methods, including a standardised survey of experts in chronic care (n = 92), an expert workshop of professionals (n = 22) and a multilingual online survey (n = 659). Using three consensus meetings involving researchers, policy makers and experts in chronic care, a limited number of core components and care recommendations was set up to develop a new chronic care model. Results: The developed 'MANAGE CARE MODEL' includes aspects of the health and social care system, resources derived from the living environment, aspects of health promotion and prevention, as well as an expanded understanding of improved outcomes as an integral part of chronic care. Conclusion: The MANAGE CARE MODEL provides...
