Characteristics of 27 systematic reviews of integrated care interventions. Review Population & integrated care terms used Adams, 2007 [12] Chronic Obstructive Pulmonary SR to determine which CCM components have been Disease implemented in patients with Chronic Obstructive Pulmonary Disease; and what combination of CCM Chronic Care Models components is associated with improved outcomes Badamgarav, 2003 [13] Rheumatoid Arthritis Disease Management Boult, 2009 [14] Chronic Disease Models Comprehensive Care Elissen, 2012 [15] Diabetes Mellitus Chronic Care Models Gensichen, 2004 [38] Congestive Heart Failure Case Management Göhler, 2006 [16] Congestive Heart Failure Disease Management Gonseth, 2004 [17] Congestive Heart Failure and Cerebrovascular Disease Aim of review Authors' conclusions Limited published data exist evaluating the efficacy of program components in chronic obstructive pulmonary disease management. However, pooled data demonstrated that patients with chronic obstructive pulmonary disease who received interventions with two or more program components had lower rates of hospitalizations and emergency/unscheduled visits and a shorter length of stay compared with control groups. Need for well-designed trials in this population. To evaluate the effectiveness of disease management There were limited data to support or refute the effectiveness of disease programs in improving functional status and reducing management programs in improving functional status in patients with RA. disability for patients with RA Additional studies are needed to confirm if a more intensive intervention may be of benefit to patients with RA, as suggested by our study. To identify promising “successful” models of comprehensive care that high-quality research has shown to be capable of improving the quality, outcomes, and efficiency of care for chronically ill older persons; that should be considered for replication or further study Many comprehensive models of chronic care for older adults have been shown to be capable of improving important outcomes, but the nation's ability to benefit from these advances will depend on the models' inherent diffusability, on additional rigorous research, and on public and private insurers' ability and willingness to reimburse providers adequately for the costs of operating these models. MA to support decision making on how best to redesign diabetes care by investigating three potential sources of heterogeneity in effectiveness across trials of diabetes care management Generally positive outcomes but differ considerably across trials. The most promising results come from studies with limited follow-up (<1 year) and by programs including more than two CCM components. Potential sources of heterogeneity between studies partly influencing the variation in effectiveness include: follow up times and variety and number of components addressed. Other sources of heterogeneity should be investigated to ensure implementation of evidence-based improvements in diabetes care. To evaluate the quality and extent of the effects of Case Management on patients with HF in outpatient primary care; Especially "complex" models of CM for patients with Congestive Heart Failure can be effective in a primary care setting. CM can prevent the fragmentation and discontinuity of care by strengthening a close contact between patient and health care provider. MA to systematically combine the evidence on the efficacy of disease management programs in the treatment of Congestive Heart Failure, to identify and explain heterogeneity in results of prior studies, and to examine for the potential of publication bias in prior studies Programs have the potential to reduce morbidity and mortality for patients with Congestive Heart Failure. The benefit of the intervention depends on age, severity of disease, guideline-based treatment at baseline, and DMP modalities. Future studies should directly compare the effect of different aspects of disease management programs for different populations. SR & MA to systematically evaluate the published evidence regarding the effectiveness of disease management programs reducing hospital re- Effectiveness at reducing re-admissions among elderly patients with Congestive Heart Failure is close to that observed in clinical trials evaluating drugs for HF, such as angiotensin-converting enzyme inhibitors, beta-blockers or digoxin. 3 Review Population & integrated care terms used Aim of review Authors' conclusions Disease Management admissions among elderly patients with HF However, studies did not compared different interventions directly, thus the relative effectiveness of types of healthcare delivery within the program is not known. To determine whether hospital-based palliative care teams improve the process or outcomes of care for patients and families at the end of life This review suggests that hospital-based palliative care teams offer some benefits, although this finding should be interpreted with caution. The study designs need to be improved and different models of providing support at the end of life in hospital need comparison. Standardized outcome measures should be used in such research and in practice. SR to evaluate the effectiveness of Diabetes Mellitus disease management programs on glycaemic control and other relevant outcomes Diabetes disease management programs can improve glycaemic control to a modest extent and can increase screening for retinopathy and foot complications. Further efforts will be required to create more effective disease management programs for patients with diabetes mellitus. SR to examine the effectiveness of multiple interventions as compared to single interventions or usual care on health outcomes and health care utilisation within the context of integrated disease management in asthma In spite of the heterogeneity of disease management studies in asthma and Chronic Obstructive Pulmonary Disease care, this review showed promising improvements in quality of life and reductions in hospitalizations, especially for triple intervention programs. Higginson, 2002 [18] End of Life Care Hospital-Based Palliative Care Knight, 2005 [19] Diabetes Mellitus Disease Management Lemmens, 2009 [20] Asthma Disease Management Lemmens, 2011 [21] Chronic Obstructive Pulmonary SR & MA to examine the effectiveness of chronic Disease care management in Chronic Obstructive Pulmonary Disease while taking heterogeneity into account, Chronic Care Management enabling the understanding of and the decision making about such programs McAlister, 2001 [22] Congestive Heart Failure Disease Management Mitchell, 2002 [23] Orthopedic, Asthma, Hypertension, Diabetes Mellitus, Frail Organized and coordinated cooperation for Managed Care Chronic Obstructive Pulmonary Disease chronic care management has the potential to improve outcomes of care. Generally positive results on QoL and hospitalizations. Inconclusive effects on ED visits and no effects on mortality. Not significant improvement on hospitalizations, ED visits and QoL. No effects on mortality. Heterogeneity for hospitalization and ED visits partly explained by the number of components but methodological study quality and length of follow-up did not significantly explain heterogeneity. Further research is needed to elucidate the diversity between Chronic Obstructive Pulmonary Disease chronic care management studies in terms of the effects measured and strengthen the support for chronic care management. SR determine whether disease management programs Disease management programs for the care of patients with Congestive Heart improve outcomes for patients with Congestive Heart Failure that involve specialized follow-up by a multidisciplinary team reduce Failure hospitalizations and appear to be cost saving. Data on mortality are inconclusive. Further studies are needed to establish the incremental benefits of the different elements of these programs. SR to determine the impact of involving GPs in specialist teams on patients’ health outcomes, the behaviour of medical practitioners, and the costs of health delivery Formal liaison between GPs and specialist services leaves most physical health outcomes unchanged, but improves functional outcomes in chronically mentally ill patients. It may confer modest long-term health benefits through improvements in patient concordance with treatment programs and more effective clinical practice. 4 Review Population & integrated care terms used Mitchell, 2008 [24] Stroke Disease Management (multidisciplinary care planning) Aim of review Authors' conclusions SR to assess the impact of coordinated multidisciplinary care planning involving primary care professionals, either wholly within primary care or by primary-secondary care teams, on outcomes in stroke, relative to usual care While multidisciplinary care planning may not unequivocally improve the care of patients with completed stroke, there may be process benefits such as improved task allocation between providers. Further study on the impact of active GP involvement in multidisciplinary care planning is warranted. Niesink, 2007 [25] Chronic Obstructive Pulmonary SR to investigate effectiveness of chronic disease Disease management programs on the quality of life of people with Chronic Obstructive Pulmonary Disease Disease Management All chronic disease management projects for people with Chronic Obstructive Pulmonary Disease involving primary care improved quality of life. In most of the studies, aspects of chronic disease management were applied to a limited extent. Quality of randomized-controlled trials was not optimal. More research is needed on chronic disease management programs in patients with Chronic Obstructive Pulmonary Disease across primary and secondary care. Norris, 2002 [26] Diabetes Mellitus SR to examine the extent and quality of the evidence of the effectiveness and economic efficiency of disease management and case management for people with diabetes; and to form the basis for guidance recommendations by the Task Force on Community Preventive Services Evidence supports the effectiveness of disease management on glycaemic control; on screening for diabetic retinopathy, foot lesions and peripheral neuropathy, and proteinuria; and on the monitoring of lipid concentrations; applicable to adults with diabetes in managed care organizations and community clinics in the United States and Europe. Case management is effective in improving both glycaemic control and provider monitoring of glycaemic control; applicable primarily in the U.S. managed care setting for adults with type 2 diabetes. Case management is effective both when delivered in conjunction with disease management and when delivered with one or more additional educational, reminder, or support interventions. SR to provide additional descriptive information on disease management programs(in improving care or reducing costs) related to Cardiovascular Disease from studies identified and effectiveness reviewed by Weingarten 2002 Disease management programs were associated with marked improvements in many different processes and outcomes of care. Only a few studies demonstrated a notable reduction in costs. Further research is needed to understand how disease management can most effectively improve the quality and cost of care for patients with chronic diseases SR of integrated care interventions and their effects on the quality of care for patients with cancer To improve integrated care for patients with cancer, a multicomponent intervention program is required focusing on patients, professionals and the organization of care. The promising interventions found in this review should be part of this program. This program should be evaluated using rigorous methods and unequivocal outcome measures linked to the intervention. Disease Management and Case Management Ofman, 2004 [27] Cardiovascular Disease (Congestive Heart Failure, Hyperlipidemia, Coronary Artery Disease, Hypertension) Disease Management Ouwens, 2009 [28] Cancer Integrated Care PeytremannBridevaux, 2008 [29] Chronic Obstructive Pulmonary SR & MA to evaluate the effectiveness of Chronic Disease Obstructive Pulmonary Disease disease-management programs (operational definition elaborated a priori) Disease Management which are more comprehensive, and used as long (Case Management, Selfterm interventions in patients with chronic diseases management, Home Rehabilitation, Integrated care, Pulmonary Rehabilitation, Chronic Obstructive Pulmonary Disease disease-management programs modestly improved exercise capacity, health-related quality of life, and hospital admissions, but not all-cause mortality. Future studies should explore the specific elements or characteristics of these programs that bring the greatest benefit. 5 Review Population & integrated care terms used Aim of review Authors' conclusions MA to determine the efficacy of interventions that were described as comprehensive discharge planning plus post-discharge support for older in patients with Congestive Heart Failure; and to quantify the effect on readmission rate, all-cause mortality, initial LOS, QOL, and overall medical costs Comprehensive discharge planning plus post discharge support for older patients with Congestive Heart Failure significantly reduced readmission rates and may improve health outcomes such as survival and QOL without increasing costs. Specific Program for Chronic Obstructive Pulmonary Disease) Phillips, 2004 [30] Congestive Heart Failure Comprehensive Discharge Planning + Post-Discharge Support Rich, 1999 [31] Congestive Heart Failure To critically evaluate the current status of Congestive Based on currently available data, Congestive Heart Failure disease management Heart Failure disease management and to identify programs appear to be a cost-effective approach to reducing morbidity and Disease Management specific areas in which additional research is needed enhancing quality of life in selected patients with Congestive Heart Failure. (multidisciplinary management) However, additional study is needed involving larger and more diverse populations to define the optimal approach to Congestive Heart Failure disease management. Smith, 2008 [32,39] Diabetes Mellitus, Congestive Heart Failure, Asthma, Patients on Oral Anticoagulant Therapy, Cancer, Hypertension, Chronic Obstructive Pulmonary Disease SR to determine the effectiveness of shared care interventions designed to improve the management of chronic disease across the primary-specialty care interface At present, there is insufficient evidence to support the introduction of shared care services into clinical practice. However, methodological shortcomings, particularly inadequate length of follow-up, may account for this lack of evidence. Further research is needed to test models of collaboration across the primaryspecialty care divide both in terms of effectiveness and sustainability over longer periods of time. To locate, appraise and evaluate the evidence for the effectiveness of a case management approach to care The evidence generated in this review suggests that nurse case managers have the potential to achieve improved health outcomes for patients with long term conditions. Further research is required to support role development and create a more targeted approach to the intervention. SR to assess the effects of different clinical service interventions in preventing death and/or hospital readmissions; and the effects of the different clinical service interventions in terms of other outcomes that may have been reported The data from this review are insufficient for forming recommendations. Further research should include adequately powered, multicenter studies. Future studies should also investigate the effect of interventions on patient's and carer's QOL, their satisfaction with the interventions and cost effectiveness. MA to classify previously published studies according to CCM component(s) and to address the following: Interventions that contained one or more program elements had beneficial effects on clinical outcomes and processes of care, and these effects were consistent across all conditions studied. The effects on quality of life were mixed, with only Chronic Disease Management (shared care) Sutherlands, 2009 [33] Diabetes Mellitus II, Chronic Obstructive Pulmonary Disease, Chronic Respiratory Disease, Congestive Heart Failure, Angina Case Management Taylor, 2005 [34] Congestive Heart Disease Disease Management (Clinical Service Organization: Multidisciplinary Care Model, Case Management, Clinic Models) Tsai 2005 [35] Asthma, Congestive Heart Failure, Diabetes Mellitus 6 Review Population & integrated care terms used Aim of review Chronic Care Models Vlieland, 1997 [36] Rheumatoid Arthritis the Congestive Heart Failure and depression studies showing benefit. Publication bias was noted for the Congestive Heart Failure studies and a subset of the asthma Studies. To assess the efficacy of multidisciplinary team care programs in Rheumatoid Arthritis Favourable effects on disease activity were seen in most trials comparing short inpatient team care with regular outpatient care. Proof of efficacy of prolonged outpatient team care is scanty. Results of trials comparing inpatient with outpatient team care remain inconclusive. MA to systematically review and evaluate quantitatively and qualitatively the published evidence regarding the characteristics and effectiveness of disease management programs All studied interventions were associated with improvements in provider adherence to practice guidelines and disease control. The type and number of interventions varied greatly, and future studies should directly compare different types of intervention to find the most effective.
