Implementation of integrated care for diabetes mellitus type 2 by two Dutch care groups: a case study.

BACKGROUND: Even though previous research has demonstrated improved outcomes of integrated care initiatives, it is not clear why and when integrated care works. This study aims to contribute to filling this knowledge gap by examining the implementation of integrated care for type 2 diabetes by two Dutch care groups. METHODS: An embedded single case study was conducted including 26 interviews with management staff, care purchasers and health professionals. The Context + Mechanism = Outcome Model was used to study the relationship between context factors, mechanisms and outcomes. Dutch integrated care involves care groups, bundled payments, patient involvement, health professional cooperation and task substitution, evidence-based care protocols and a shared clinical information system. Community involvement is not (yet) part of Dutch integrated care. RESULTS: Barriers to the implementation of integrated care included insufficient integration between the patient databases, decreased earnings for some health professionals, patients' insufficient medical and policy-making expertise, resistance by general practitioner assistants due to perceived competition, too much care provided by practice nurses instead of general practitioners and the funding system incentivising the provision of care exactly as described in the care protocols. Facilitators included performance monitoring via the care chain information system, increased earnings for some health professionals, increased focus on self-management, innovators in primary and secondary care, diabetes nurses acting as integrators and financial incentives for guideline adherence. Economic and political context and health IT-related barriers were discussed as the most problematic areas of integrated care implementation. The implementation of integrated care led to improved communication and cooperation but also to insufficient and unnecessary care provision and deteriorated preconditions for person-centred care. CONCLUSIONS: Dutch integrated diabetes care is still a work in progress, in the academic and the practice setting. This makes it difficult to establish whether overall quality of care has improved. Future efforts should focus on areas that this study found to be problematic or to not have received enough attention yet. Increased efforts are needed to improve the interoperability of the patient databases and to keep the negative consequences of the bundled payment system in check. Moreover, patient and community involvement should be incorporated.

Relevance of hypersexual disorder to family medicine and primary care as a complex multidimensional chronic disease construct.

Hypersexual disorder (HD) is not defined in a uniform way in the psychiatric literature. In the absence of solid evidence on prevalence, causes, empirically validated diagnostic criteria, instruments for diagnosis, consistent guidelines on treatment options, medical and psychosocial consequences, and type of caregivers that need to be involved, HD remains a controversial and relatively poorly understood chronic disease construct. The role of family medicine in the detection, treatment, and followup of HD is not well studied. The purpose of this paper is to describe the complexity of HD as a multidimensional chronic disease construct and its relevance to family medicine and primary care.

A theoretical lens for revealing the complexity of chronic care.

The increasing prevalence of co-occurring multiple chronic conditions in an aging population has influenced the debate on complexity in chronic care and nowadays provides an impetus to the reform of numerous health systems. This article presents a theoretical lens for understanding the complexity of chronic care based on research and debate conducted in the context of multiple quality improvement programs over the last five years in Belgium and The Netherlands. We consider four major components of complexity in chronic care against a background of complex adaptive systems: (1) case (patient) complexity; (2) care complexity; (3) quality assessment complexity; and (4) health systems complexity. Each of these components represents a range of elements that contribute to the picture of complexity in chronic care. We emphasize that planning for chronic care requires equal attention to the complexity of all four components. It also requires multifaceted interventions and implementation strategies that target improvements in multiple outcomes related to the structural, process, and outcome components of care. Further empirical research is needed to assess the validity of our complexity framework in the health-care environment.

Reported barriers to evaluation in chronic care: experiences in six European countries.

INTRODUCTION: The growing movement of innovative approaches to chronic disease management in Europe has not been matched by a corresponding effort to evaluate them. This paper discusses challenges to evaluation of chronic disease management as reported by experts in six European countries. METHODS: We conducted 42 semi-structured interviews with key informants from Austria, Denmark, France, Germany, The Netherlands and Spain involved in decision-making and implementation of chronic disease management approaches. Interviews were complemented by a survey on approaches to chronic disease management in each country. Finally two project teams (France and the Netherlands) conducted in-depth case studies on various aspects of chronic care evaluation. RESULTS: We identified three common challenges to evaluation of chronic disease management approaches: (1) a lack of evaluation culture and related shortage of capacity; (2) reluctance of payers or providers to engage in evaluation and (3) practical challenges around data and the heterogeity of IT infrastructure. The ability to evaluate chronic disease management interventions is influenced by contextual and cultural factors. CONCLUSIONS: This study contributes to our understanding of some of the most common underlying barriers to chronic care evaluation by highlighting the views and experiences of stakeholders and experts in six European countries. Overcoming the cultural, political and structural barriers to evaluation should be driven by payers and providers, for example by building in incentives such as feedback on performance, aligning financial incentives with programme objectives, collectively participating in designing an appropriate framework for evaluation, and making data use and accessibility consistent with data protection policies.

Co-ordination and management of chronic conditions in Europe: the role of primary care--position paper of the European Forum for Primary Care.

Healthcare systems in Europe struggle with inadequate co-ordination of care for people with chronic conditions. Moreover, there is a considerable evidence gap in the treatment of chronic conditions, lack of self-management, variation in quality of care, lack of preventive care, increasing costs for chronic care, and inefficient use of resources. In order to overcome these problems, several approaches to improve the management and co-ordination of chronic conditions have been developed in European healthcare systems. These approaches endeavour to improve self-management support for patients, develop clinical information systems and change the organisation of health care. Changes in the delivery system design and the development of decision support systems are less common. Almost as a rule, the link between healthcare services and community resources and policies is missing. Most importantly, the integration between the six components of the chronic care model remains an important challenge for the future. We find that the position of primary care in healthcare systems is an important factor for the development and implementation of new approaches to manage and coordinate chronic conditions. Our analysis supports the notion that countries with a strong primary care system tend to develop more comprehensive models to manage and co-ordinate chronic conditions.

Critical appraisal of the literature on economic evaluations of substitution of skills between professionals: a systematic literature review.

OBJECTIVE: Substitution of skills has been introduced to increase health service efficiency, but little evidence is available about its cost-effectiveness. This systematic review aims to identify economic evaluations of substitution between professionals, to assess the quality of the study methods applied and to value the results for decision making. METHODS: Publications between January 1996 and November 2006 were searched in Medline, Cochrane, Cinahl, database of Health Technology Assessments, EPOC and Embase. Randomized controlled trials (RCTs), cost-benefit analysis, interrupted time series design and systematic reviews were selected. The methodological quality of the papers was reviewed, using the critical appraisal of Drummond and the EPOC list. RESULTS: Eleven studies were finally included of 7605 studies: three cost-effectiveness studies, three cost-minimization studies and five studies related to partial economic evaluations. Small numbers of participating professionals and several limitations in the cost valuation and the measurement of costs were identified. CONCLUSIONS: Several potential limitations influence the validity and generalizability. Full economic evaluations per se are of limited value for making decisions about substitution of skills. The tenuous relationship between structural, process and outcome variables is not sufficient investigated. For meaningfully placing the costs and consequences of substitution of skills in the context of health care and generating relevant data for decision making, it is strongly recommended to combine an economic evaluation (RCT) with an observational longitudinal study.

Cost-utility of a disease management program for patients with asthma.

OBJECTIVES: The long-term cost-utility of a disease management program (DMP) for adults with asthma was assessed compared to usual care. METHODS: A DMP for patients with asthma has been developed and implemented in the region of Maastricht (The Netherlands). By integrating care, the program aims to continuously improve quality of care within existing budgets. A clinical trial was performed over a period of 15 months to collect data on costs and effects of the program and usual care. These data were used to inform a probabilistic decision-analytic model to estimate the 5-year impact of the program beyond follow-up. A societal perspective was adopted, with outcomes assessed in terms of costs per quality-adjusted life-year (QALY). RESULTS: The DMP is associated with a gain in QALYs compared to usual care (2.7+/-.2 versus 3.4+/-.8), at lower costs (3,302+/-314 euro versus 2,973+/-304 euro), thus leading to dominance. The probability that disease management is the more cost-effective strategy is 76 percent at a societal willingness to pay (WTP) for an additional QALY of 0 euro, reaching 95 percent probability at a WTP of 1,000 euro per additional QALY. CONCLUSIONS: Organizing health care according to the principles of disease management for adults with asthma has a high probability of being cost-effective and is associated with a gain in QALYs at lower costs.

Health technology assessment of asthma disease management programs.

PURPOSE OF REVIEW: To provide a critical opinion on the extent to which asthma disease management programs currently improve the effectiveness and efficiency of care and directions for future policy and research. RECENT FINDINGS: The methodological quality of health technology assessment of asthma disease management programs remains moderate. Asthma disease management programs are predominantly educational and organizational in nature and focus either on children or on adults. Paediatric disease management programs make more effort to outreach into patients' living environments and show higher participation rates than those targeting adults. Reductions in asthma-related hospitalization, emergency department, and unplanned clinic visits range from 0 to 85%, 87% and 71%, respectively. Aspects of self-management and organization of care improved after the implementation of disease management programs. Almost no impact on asthma symptoms, lung function or the use of long-term control medication was found. SUMMARY: There is accumulating 'circumstantial' evidence that disease management programs reduce resource utilization. The analytical rigor and uniformity of health technology assessment of asthma disease management programs has improved, but the generalizability of results remains uncertain. Practical, multicentre, clinical trials including broad representative study samples should be performed in different settings to increase methodological quality and substantiate current findings.

Evaluation of a regional disease management programme for patients with asthma or chronic obstructive pulmonary disease.

OBJECTIVE: To assess the impact of a population-based disease management programme for adult patients with asthma or chronic obstructive pulmonary disease (COPD) on process measures, intermediate outcomes, and endpoints of care. DESIGN: Quasi-experimental design with 12-month follow-up. SETTING: Region of Maastricht (the Netherlands) including university hospital and 16 general practices. PARTICIPANTS: Nine hundred and seventy-five patients of whom 658 have asthma and 317 COPD. INTERVENTION: Disease management programme. MAIN OUTCOME MEASURE(S): Endpoints of care are respiratory health, health utility, patient satisfaction, and total health care costs related to asthma or COPD. RESULTS: Quality aspects of care, disease control, self-care behaviour, smoking status, disease-specific knowledge, and patients' satisfaction improved after implementation of the programme. Lung function was not affected by implementation of the programme. For COPD patients, a significant improvement in health utility was found. For patients with asthma, significant cost savings were measured. CONCLUSIONS: Organizing health care according to principles of disease management for adults with asthma or COPD is associated with significant improvements in several processes and outcomes of care, while costs of care do not exceed the existing budget.

Are we measuring what matters in health technology assessment of disease management? Systematic literature review.

OBJECTIVES: An overview was produced of indicators currently used to assess disease management programs and, based on these findings, provide a framework regarding sets of indicators that should be used when taking the aims and types of disease management programs into account. METHODS: A systematic literature review was performed. RESULTS: Thirty-six studies met the inclusion criteria. It appeared that a link between aims of disease management and evaluated structure, process, as well as outcome indicators does not exist in a substantial part of published studies on disease management of diabetes and asthma/chronic obstructive pulmonary disease, especially when efficiency of care is concerned. Furthermore, structure indicators are largely missing from the evaluations, although these are of major importance for the interpretation of outcomes for purposes of decision-making. Efficiency of disease management is mainly evaluated by means of process indicators; the use of outcome indicators is less common. Within a framework, structure, process, and outcome indicators for effectiveness and efficiency are recommended for each type of disease management program. CONCLUSIONS: The link between aims of disease management and evaluated structure, process, and outcome indicators does not exist in a substantial part of published studies on disease management. The added value of this study mainly lies in the development of a framework to guide the choice of indicators for health technology assessment of disease management.
