Relevant models and elements of integrated care for multi-morbidity: Results of a scoping review

BACKGROUND

In order to provide adequate care for the growing group of persons with multi-morbidity, innovative integrated care programmes are appearing. The aims of the current scoping review were to i) identify relevant models and elements of integrated care for multi-morbidity and ii) to subsequently identify which of these models and elements are applied in integrated care programmes for multi-morbidity.

METHODS

A scoping review was conducted in the following scientific databases: Cochrane, Embase, PubMed, PsycInfo, Scopus, Sociological Abstracts, Social Services Abstracts, and Web of Science. A search strategy encompassing a) models, elements and programmes, b) integrated care, and c) multi-morbidity was used to identify both models and elements (aim 1) and implemented programmes of integrated care for multi-morbidity (aim 2). Data extraction was done by two independent reviewers. Besides general information on publications (e.g. publication year, geographical region, study design, and target group), data was extracted on models and elements that publications refer to, as well as which models and elements are applied in recently implemented programmes in the EU and US.

RESULTS

In the review 11,641 articles were identified. After title and abstract screening, 272 articles remained. Full text screening resulted in the inclusion of 92 articles on models and elements, and 50 articles on programmes, of which 16 were unique programmes in the EU (n=11) and US (n=5). Wagner's Chronic Care Model (CCM) and the Guided Care Model (GCM) were most often referred to (CCM n=31; GCM n=6); the majority of the other models found were only referred to once (aim 1). Both the CCM and GCM focus on integrated care in general and do not explicitly focus on multi-morbidity. Identified elements of integrated care were clustered according to the WHO health system building blocks. Most elements pertained to 'service delivery'. Across all components, the five elements referred to most often are person-centred care, holistic or needs assessment, integration and coordination of care services and/or professionals, collaboration, and self-management (aim 1). Most (n=10) of the 16 identified implemented programmes for multi-morbidity referred to the CCM (aim 2). Of all identified programmes, the elements most often included were self-management, comprehensive assessment, interdisciplinary care or collaboration, person-centred care and electronic information system (aim 2).

CONCLUSION

Most models and elements found in the literature focus on integrated care in general and do not explicitly focus on multi-morbidity. In line with this, most programmes identified in the literature build on the CCM. A comprehensive framework that better accounts for the complexities resulting from multi-morbidity is needed.

Chronic case management: Clinical governance with cost reductions

INTRODUCTION

With increasing global impact of chronic degenerative non-communicable diseases (CDNCD), multidisciplinary chronic disease management care programs (CDMCP) come as a solution to improve the quality of patients care.

METHOD

We conducted a cross-sectional epidemiologic prospective cohort study with data comparing a group of patients monitored by a CDMCP with subjects without CDMCP care, from 2010 to 2012. The patients monitored in this program were selected because they presented CDNCD with frequent hospitalization and/or emergency care in the year prior to study selection. Also, the patients could be referred to the program by their physicians and/or other programs such as HomeCare or family medicine. All costs related to the program were included and compared with the costs of users with the same epidemiological profile who opted for not participating in the CDMCP.

RESULTS

We analyzed data from 1,256 cases, including 639 (51%) men and 617 (49%) women. The mean age was 56.99 years and 73% were older than 50 years. There was a prevalence of 34% (428) cases with ischemic heart disease (myocardial infarction and stroke) and 17% (210) with neoplasms. The cases studied showed a reduction of 79% in the number of days of hospitalization compared with the cases without CDMCP monitoring. The average reduction of total costs (hospitalizations, emergency room visits and/or disease complications) was 31.94%, with average reduction of 8.36% in monthly costs.

CONCLUSION

Multidisciplinary monitoring carried out by CDNCD patient management programs can reduce hospitalizations, emergency room visits and complications, positively impacting the costs with health care.

Implementing integrated care: A synthesis of experiences in three European countries

Many countries are experimenting with new models to better integrate care; yet, innovative care models are often implemented as time-limited, localised projects with limited impact on service delivery more broadly. This paper seeks to understand the processes behind successful projects that achieved some form of ‘routinisation’ and informed system-wide integrated care strategies. It draws on detailed case studies of three integrated care experiments: the ‘Integrated effort for people living with chronic diseases’ project in Denmark; the Gesundes Kinzigtal network in Germany; and Zio, a care group in the Maastricht region in the Netherlands. It explores how they were developed, implemented and sustained, and how they impacted the wider system context. All three models implicitly or explicitly adopted processes shown to be conducive to the dissemination of innovations, including dedicated time and resources, support and advocacy, leadership and management, stakeholder involvement, communication and networks, adaptation to local context and feedback. Each showed robust evidence of improvements on a number of service and patient outcomes and these findings were central to their wider impacts, shaping country-wide integrated care polices. However, the wider dissemination of projects occurred in an incremental and somewhat haphazard way. To further redesign health and social care a more formal strategy, alongside resources, may thus be needed to provide funders and providers with genuine incentives to invest in new business models of care. There remains a crucial need for better understanding of specific local conditions that influence implementation and sustainability to enable translation to other contexts and settings.

Substitution of Hospital Care with Primary Care: Defining the Conditions of Primary Care Plus

OBJECTIVE

To analyse barriers and facilitators in substituting hospital care with primary care to define preconditions for successful implementation.

METHODS

A descriptive feasibility study was performed to collect information on the feasibility of substituting hospital care with primary care. General practitioners were able to refer patients, about whom they had doubts regarding diagnosis, treatment and/or the need to refer to hospital care, to medical specialists who performed low-complex consultations at general practitioner practices. Qualitative data were collected through interviews with general practitioners and medical specialists, focus groups and notes from meetings in the Netherlands between April 2013 and January 2014. Data were analysed using a conventional content analysis which resulted in categorised barriers, facilitators and policy adjustments, after which preconditions were formulated.

RESULTS

The most important preconditions were make arrangements on governmental level, arrange a collective integrated IT-system, determine the appropriate profile for medical specialists, design a referral protocol for eligible patients, arrange deliberation possibilities for general practitioners and medical specialists and formulate a diagnostic protocol.

CONCLUSIONS

The barriers, facilitators and formulated preconditions provided relevant input to change the design of substituting hospital care with primary care.

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 a result, the urgency to tackle the threat of chronic diseases in Greece by promoting public health and providing effective chronic care while flattening the rising health care expenditure is eminent. In many European countries, integrated care is seen as a means to achieve this. The aim of this paper was to support Greek health policy makers to develop an action plan from 2015 onwards, to integrate care by bridging local policy context and needs with knowledge and experience from other European countries. To achieve this aim, we adopted a conceptual framework developed by the World Health Organization on one hand to analyse the status of integrated care in Greece, and on the other to develop an action plan for reform. The action plan was based on an analysis of the Greek health care system regarding prerequisite conditions to integrate care, a clear understanding of its context and successful examples of integrated care from other European countries. This study showed that chronic diseases are poorly addressed in Greece and integrated care is in embryonic stage. Greek policy makers have to realise that this is the opportunity to make substantial reforms in chronic care. Failing to reform towards integrated care would lead to the significant risk of collapse of the Greek health care system with all associated negative consequences. The action plan provided in this paper could support policy makers to make the first serious step to face this challenge. The details and specifications of the action plan can only be decided by Greek policy makers in close cooperation with other health and social care partners. This is the appropriate time for doing so.

[Analysis of type 2 diabetes-induced late effects based on administrative data of social insurance in Austria and implications for the evaluation of the DMP diabetes mellitus]

The present study analyses administrative data of medical services related to the distribution of diabetes mellitus type 2-induced late effects. Pseudonymous statutory health insurance data of all Austrian social security institutions for the years 2006/2007 in outpatient and inpatient (performance and diagnostic data) setting were used. Type 2 diabetics have been identified by prescribed medication. The specific late effects were defined as endpoints and the respective diagnoses and health performances were extracted. The study population included 7,945,774 insured. The percentage of the defined late effects was significantly higher in diabetics than in persons from the general population, with exception for kidney transplantation. The risk of a late effect was greatest among diabetics for an amputation. The results of this study can be used as a baseline for the evaluation of DMP diabetes. The administrative data used are limited for answering the defined research questions. Anyway, the data quality must be improved and unified in Austria.

Is Europe putting theory into practice? A qualitative study of the level of self-management support in chronic care management approaches

Background

Self-management support is a key component of effective chronic care management, yet in practice appears to be the least implemented and most challenging. This study explores whether and how self-management support is integrated into chronic care approaches in 13 European countries. In addition, it investigates the level of and barriers to implementation of support strategies in health care practice.

Methods

We conducted a review among the 13 participating countries, based on a common data template informed by the Chronic Care Model. Key informants presented a sample of representative chronic care approaches and related self-management support strategies. The cross-country review was complemented by a Dutch case study of health professionals’ views on the implementation of self-management support in practice.

Results

Self-management support for chronically ill patients remains relatively underdeveloped in Europe. Similarities between countries exist mostly in involved providers (nurses) and settings (primary care). Differences prevail in mode and format of support, and materials used. Support activities focus primarily on patients’ medical and behavioral management, and less on emotional management. According to Dutch providers, self-management support is not (yet) an integral part of daily practice; implementation is hampered by barriers related to, among others, funding, IT and medical culture.

Conclusions

Although collaborative care for chronic conditions is becoming more important in European health systems, adequate self-management support for patients with chronic disease is far from accomplished in most countries. There is a need for better understanding of how we can encourage both patients and health care providers to engage in productive interactions in daily chronic care practice, which can improve health and social outcomes.

Management of diabetes in primary care: a structured-care approach

BACKGROUND

In the Irish Midland Health Service Executive (HSE) Diabetes Structured Care Project, additional resources were targeted at general practice in the absence of a local hospital-based specialized diabetes unit.

OBJECTIVE

We assessed the performance of the Midland HSE Diabetes Structured Care programme in 2003, bench-marked against Primary Care Trust (PCT) data from the 2003/2004 National Diabetes Audit for England.

METHODS

Data on 947 patients (72% of eligible patients) from all 20 general practices participating in the structured-care programme were collected retrospectively over a 12-month period. The data included demographic and clinical variables as well as key process-of-care and intermediate outcome indicators used in the National Diabetes Audit for England.

RESULTS

The level of recording of process-of-care measures was near or above the upper quartile for PCTs in England. The proportion of patients with HbA(1c) concentrations at target levels (<6.5%) in the Midlands HSE project (26.8%) was virtually identical to the upper quartile level for PCTs in England (27.4%). The proportion of patients reaching target total cholesterol levels (<5.0 mmol/l) (54.6%) was close to the mean for PCTs in England (56.6%), and performance with regard to target blood pressure levels was equally poor in both the Midlands HSE (18.0%) and in PCTs in England (20.8%).

CONCLUSION

Primary-care-led structured care, with relatively limited but well-focused investment, can achieve quality of care for patients with diabetes, comparable to international best practice.

The effectiveness and efficiency of disease management programs for patients with chronic diseases

Objective:

Disease management (DM) approach is increasingly advocated as a means of improving effectiveness and efficiency of healthcare for chronic diseases. To evaluate the evidence on effectiveness and efficiency of DM, evidence synthesis was carried out.

Methods:

To locate eligible meta-analyses and systematic reviews, we searched Medline, EMBASE, the Cochrane Library, SCI-EXPANDED, SSCI, A&HCI, DARE, HTA and NHS EED from 1995 to 2010. Two reviewers independently extracted data and assessed a study quality.

Results:

Twenty-eight meta-analyses and systematic reviews were included for synthesizing evidence. The proportion of articles which observed improvement with a reasonable amount of evidence was the highest at process (69%), followed by health services (63%), QOL (57%), health outcomes (51%), satisfaction (50%), costs (38%) and so on. As to mortality, statistically significant results were observed only in coronary heart disease. Important components in DM, such as a multidisciplinary approach, were identified.

Conclusion:

The evidence synthesized shows considerable evidence in the effectiveness and efficiency of DM programs in process, health services, QOL and so on. The question is no longer whether DM programs work, but rather which type or component of DM programs works best and efficiently in the context of each healthcare system or country.

Early results from adoption of bundled payment for diabetes care in the Netherlands show improvement in care coordination

In 2010 a bundled payment system for diabetes care, chronic obstructive pulmonary disease care, and vascular risk management was introduced in the Netherlands. Health insurers now pay a single fee to a contracting entity, the care group, to cover all of the primary care needed by patients with these chronic conditions. The initial evaluation of the program indicated that it improved the organization and coordination of care and led to better collaboration among health care providers and better adherence to care protocols. Negative consequences included dominance of the care group by general practitioners, large price variations among care groups that were only partially explained by differences in the amount of care provided, and an administrative burden caused by outdated information and communication technology systems. It is too early to draw conclusions about the effects of the new payment system on the quality or the overall costs of care. However, the introduction of bundled payments might turn out to be a useful step in the direction of risk-adjusted integrated capitation payments for multidisciplinary provider groups offering primary and specialty care to a defined group of patients.

Overcoming fragmentation in health care: chronic care in Austria, Germany and the Netherlands

The growing recognition of care fragmentation is causing many countries to explore new approaches to healthcare delivery that can bridge the boundaries between professions, providers and institutions and so better support the rising number of people with chronic health problems. This paper examines the role of the regulatory, funding and organisational context for the development and implementation of approaches to chronic care, using examples from Austria, Germany and the Netherlands. We find that the three countries have implemented a range of policies and approaches to achieve better coordination within and across the primary and secondary care interface and so better meet the needs of patients with chronic conditions. This has involved changes to the regulatory framework to support more coordinated approaches to care (Austria, Germany), coupled with financial incentives (Austria, Germany) or changes in payment systems (the Netherlands). What is common to the three countries is the comparative ‘novelty’ of policies and approaches aimed at fostering coordinated care; however, the evidence of their impact remains unclear.

Joint and distinct risk factors associated with micro- and macrovascular complications in a cohort of type 2 diabetic patients cared through disease management

We analysed the risk factors associated with diabetic complications in the cohort of patients assisted by a type 2 diabetes mellitus (T2DM) shared-care program. We analysed registry data from 16,136 T2DM patients. Of them, 4,781 had microangiopathy, 3,469 CV events. They were 70.5 ± 17.1 years old, 50% were male, disease duration 13.3 ± 7.8 years, BMI 28.7 ± 4.9 kg/m², HbA1c 7.08 ± 1.23%, FBG 134.7 ± 35.7 mg/dl, 2hPPBG 163.9 ± 47.8 mg/dl, 12.5% smokers. Cholesterol 202.5 ± 37.6 mg/dl, HDL 51.4 ± 20.4 mg/dl, LDL 126.5 ± 36.0 mg/dl, triglyceride 146.2 ± 72.4 mg/dl, SBP 137.8 ± 14.2 mmHg, DBP 80.7 ± 10.8 mmHg, 10-year CV risk score 13.7 ± 9.1; 70.4% had no microangiopathy-i.e. renal, retinal, peripheral nerve disease-and 78.5% of patients had no CV events. Age-adjusted risk factors associated with diabetic complications were male gender, HbA1c, 2hPPBG, HDL, and triglyceride. FBG and SBP were associated with microangiopathy, whereas smoking with cardiovascular events. Optimal targets were reached in: FBG 17%, 2hPPBG 8%, HbA1c 21%, cholesterol 17%, HDL 8%, LDL 5%, triglyceride 20%, SBP 13%, DBP 30%. Drug profiles showed 13% using metformin, 28% sulphonilureas, 26% bitherapy, 4% insulin; 12% statins, 16% anti-platelets, 27% anti-hypertensives, 2% anti-coagulants. T2DM patients showed an acceptable CV risk profile. Joint risk factors for diabetic complications were male gender, HbA1c, 2hPPBG, HDL, and triglyceride. Distinct risk factors were FBG and SBP for micro- and smoking for macrovascular disease. A targeted-to-treat approach needs more attention in the care of T2DM patients.

An integrated chronic care program for patients with atrial fibrillation: study protocol and methodology for an ongoing prospective randomised controlled trial

BACKGROUND

Adherence to guidelines for the management of atrial fibrillation (AF) is often poor, although this is associated with improved morbidity and mortality in such patients. Increasing numbers of programs are designed to enhance appropriate counselling, treatment and coordinated care delivery including the nurse-led, guidelines-based, software-supported integrated chronic care program (ICCP) for patients with AF reported here.

OBJECTIVES

This paper outlines the study protocol and methodology currently being used to evaluate the effectiveness of a newly developed nurse-led, guideline-based, software-supported ICCP for patients with AF.

DESIGN AND METHODS

Evaluation of the ICCP is currently being carried out in the outpatient care setting known as the AF-Clinic. A prospective randomised controlled trial is currently underway in the outpatient AF-Clinic of a University Hospital in the Netherlands in cooperation with the collaborating university. The primary outcome measures are cardiovascular hospitalisation and/or death. Secondary outcome measures include guideline adherence, patient knowledge about their condition, quality of life, satisfaction and other outcome measurements such as cost-effectiveness.

PARTICIPANTS

It was calculated that 698 participants are needed to demonstrate discernible outcomes in relation to the primary endpoint (349 patients in each group) with follow-up after 1 year.

RESULTS

The study started in January 2007 and the first results are expected in the beginning of 2010.

CONCLUSIONS

It is hypothesised that the ICCP may contribute towards closing the gap between guideline recommendations and current practice in the management of atrial fibrillation. Furthermore, it is hypothesised that the program has the potential to optimise the management of AF patients and improve the efficiency and coordination of patient care. This may lead to better patient outcomes including improved quality of life and patient satisfaction in such patients.

Autonomous decision making and moral capacities

This article examines how people with type 2 diabetes perceive autonomous decision making and which moral capacities they consider important in diabetes nurses' support of autonomous decision making. Fifteen older adults with type 2 diabetes were interviewed in a nurse-led unit. First, the data were analysed using the grounded theory method. The participants described a variety of decision-making processes in the nurse and family care-giver context. Later, descriptions of the decision-making processes were analysed using hermeneutic text interpretation. We suggest first- and second-order moral capacities that nurses specializing in diabetes need to promote the autonomous decision making of their patients. We recommend nurses to engage in ongoing, interactive reflective practice to further develop these moral capacities.

Substitution of specialized rheumatology nurses for rheumatologists in the diagnostic process of fibromyalgia: a randomized controlled trial

OBJECTIVE

To evaluate the substitution of specialized rheumatology nurses for rheumatologists in diagnosing fibromyalgia (FM).

METHODS

Referred patients with FM symptoms (n = 193) were randomized to a study group diagnosed by a specialized rheumatology nurse (SRN group, n = 97) or to a control group diagnosed by a rheumatologist (RMT group, n = 96). SRN patients were seen within 3 weeks by a nurse who took structured history and initiated routine laboratory tests. During a 5-minute supervision session, the rheumatologist was informed by the nurse about medical history, performed a brief physical examination, and confirmed or rejected the nurse's diagnosis. RMT patients were seen by a rheumatologist after a regular waiting period of 3 months. Outcome measures were initial agreement between the nurse and rheumatologist in the SRN group, final diagnosis after 12-24 months of followup, patient satisfaction, and diagnostic costs.

RESULTS

The mean waiting time after randomization was 2.8 and 12.1 weeks in the SRN and RMT groups, respectively. Eight RMT patients cancelled their appointments because of the waiting time. Excellent agreement (kappa = 0.91) between rheumatologists and nurses was found. After 12-24 months of followup, none of the initial diagnoses were recalled in either group. SRN patients were significantly more satisfied than RMT patients. Mean diagnostic costs were lower in the SRN group (euro219) than in the RMT group (euro281) (95% uncertainty interval euro-103, euro-20).

CONCLUSION

Substituting specialized nurses for rheumatologists in the diagnostic process of FM is a trustworthy and successful approach that saves waiting time, provides greater patient satisfaction, and is cost-effective.

Chronic disease management in primary care: from evidence to policy

OBJECTIVES

To review the effectiveness of chronic disease management interventions for physical health problems in the primary care setting, and to identify policy options for implementing successful interventions in Australian primary care.

METHODS

We conducted a systematic review with qualitative data synthesis, using the Chronic Care Model as a framework for analysis between January 1990 and February 2006. Interventions were classified according to which elements were addressed: community resources, health care organisation, self-management support, delivery system design, decision support and/or clinical information systems. Our major findings were discussed with policymakers and key stakeholders in relation to current and emerging health policy in Australia.

RESULTS

The interventions most likely to be effective in the context of Australian primary care were engaging primary care in self-management support through education and training for general practitioners and practice nurses, and including self-management support in care plans linked to multidisciplinary team support. The current Practice Incentives Payment and Service Incentives Payment programs could be improved and simplified to encourage guideline-based chronic disease management, integrating incentives so that individual patients are not managed as if they had a series of separate chronic diseases. The use of chronic disease registers should be extended across a range of chronic illnesses and used to facilitate audit for quality improvement. Training should focus on clear roles and responsibilities of the team members.

CONCLUSION

The Chronic Care Model provides a useful framework for understanding the impact of chronic disease management interventions and highlights the gaps in evidence. Consultation with stakeholders and policymakers is valuable in shaping policy options to support the implementation of the National Chronic Disease Strategy in primary care.

Self-management of type 2 diabetes mellitus: a qualitative investigation from the perspective of participants in a nurse-led, shared-care programme in the Netherlands

BACKGROUND

Diabetes mellitus is a major public health problem. Little is known about how people with type 2 diabetes experience self-management in a nurse-led, shared-care programme. The purpose of this article is to report an empirically grounded conceptualization of self-management in the context of autonomy of people with type 2 diabetes.

METHODS

This study has a qualitative descriptive, and exploratory design with an inductive approach. Data were collected by means of in-depth interviews. The sample consisted of older adults with type 2 diabetes in a nurse-led, shared-care setting. The data analysis was completed by applying the constant comparative analysis as recommended in grounded theory.

RESULTS

People with type 2 diabetes use three kinds of self-management processes: daily, off-course, and preventive. The steps for daily self-management are adhering, adapting, and acting routinely. The steps for off-course self-management are becoming aware, reasoning, deciding, acting, and evaluating. The steps for preventive self-management are experiencing, learning, being cautious, and putting into practice. These processes are interwoven and recurring.

CONCLUSION

Self-management consists of a complex and dynamic set of processes and it is deeply embedded in one's unique life situation. Support from diabetes specialist nurses and family caregivers is a necessity of self-managing diabetes.

Autonomy through identification: a qualitative study of the process of identification used by people with type 2 diabetes

AIMS AND OBJECTIVES

The aim of this study is to clarify the process of identification with diabetes as a dimension of autonomy as described by people with type 2 diabetes.

BACKGROUND

People with type 2 diabetes view autonomy as competency in shaping one's life. This concept of autonomy has seven dimensions, which emerged as categories in prior research. Dynamic processes shape these dimensions of autonomy. One of the dimensions of autonomy is identification.

METHOD

This study has a qualitative descriptive and exploratory design and an inductive approach as described in grounded theory. Data were collected by means of in-depth interviews. The sample consisted of 15 people with type 2 diabetes mellitus in a nurse-led, shared-care setting in the Netherlands.

RESULTS

The phases of identification are comprehending, struggling, evaluating and mastering. Each phase has its own characteristics. Identifying with the diabetes is a non-linear, cyclical and continuous process because people with diabetes have to deal with changing conditions.

CONCLUSION

The dynamics of identification is directed to a process of identifying with diabetes and its care requirement. Recognizing identification as an element of autonomy enables nurses to adopt a more patient-oriented view of autonomy.

RELEVANCE TO CLINICAL PRACTICE

Nursing that fosters the process of identification promotes autonomy. This implies that a person with diabetes should be able to identify with the nurse's interventions. Hence it is vital that nurses build supportive partnerships when providing care for such a patient.

Polymorbidity in diabetes in older people: consequences for care and vocational training

OBJECTIVE

To investigate the prevalence of complicating and concurrent morbidities in older diabetic patients and to evaluate to what extent their occurrence affects the burden of disease and use of medical healthcare.

STUDY DESIGN

Cross-sectional analysis of retrospectively obtained data on comorbidities and use of medical healthcare. Healthcare registration systems were used to retrieve data on 300 patients with diabetes aged >or=60 years who, according to the severity of their disease and intensity of care required, were treated in a regional general practitioner (GP), diabetes nurse specialist (DNS) or medical specialist (MS) practice.

RESULTS

Complicating and concurrent morbidities were often found irrespective of the type of practice involved. After adjustments for differences in sex, age and glycosylated haemoglobin (HbA1c), the extent of complicating comorbidities showed sequential increases in patients managed by GP, DNS and MS (mean number of 3.6, 4.7 and 6.7, respectively; p(trend)<0.001). However, the mean number of concurrent comorbidities was similar across all three settings (2.1, 1.8 and 2.0, respectively). Both complicating and concurrent comorbidities were similarly associated with the extent of drug use (beta = 0.49 (95% CI 0.40 to 0.58) and beta = 0.57 (95% CI 0.52 to 0.72), respectively) and the number of consultations with specialists other than the main care giver (beta = 1.19 (95% CI 1.15 to 1.24) and beta = 1.21 (95% CI 1.14 to 1.28), respectively). However, the mean number of different specialists involved in a patient's care per additional concurrent comorbidity was twice as high as per any additional complicating comorbidity (beta = 0.60 (95% CI 0.48 to 0.71) vs beta = 0.31 (95% CI 0.24 to 0.39)).

CONCLUSIONS

The use of healthcare facilities by older patients with diabetes is substantial, irrespective of the complexity of the disease and the kind of practice involved. The common manifestation of complicating and concurrent comorbidities and their varying complexity in individual patients requires a patient-oriented rather than a disease-oriented approach and vocational training programmes for care givers that are tailored to the complexity of multiple chronic diseases.

A disease management programme for patients with diabetes mellitus is associated with improved quality of care within existing budgets

AIM

To assess the impact of a disease management programme for patients with diabetes mellitus (Type 1 and Type 2) on cost-effectiveness, quality of life and patient self-management. By organizing care in accordance with the principles of disease management, it is aimed to increase quality of care within existing budgets.

METHODS

Single-group, pre-post design with 2-year follow-up in 473 patients.

RESULTS

Substantial significant improvements in glycaemic control, health-related quality of life (HRQL) and patient self-management were found. No significant changes were detected in total costs of care. The probability that the disease management programme is cost-effective compared with usual care amounts to 74%, expressed in an average saving of 117 per additional life year at 5% improved HRQL.

CONCLUSION

Introduction of a disease management programme for patients with diabetes is associated with improved intermediate outcomes within existing budgets. Further research should focus on long-term cost-effectiveness, including diabetic complications and mortality, in a controlled setting or by using decision-analytic modelling techniques.

Patient autonomy in nurse-led shared care: a review of theoretical and empirical literature

AIM

This paper presents a review of the theoretical and empirical literature addressing patient autonomy and how nurses can support patient autonomy.

BACKGROUND

Nurse-led, shared care settings provide needs-based care to patients who are encouraged to participate actively in their care. Patient autonomy is a complex ethical concept with many different meanings. As a result, nurses must solve various problems to foster patient autonomy successfully.

METHOD

Two methods were used to identify literature for the review: (a) a search of the MEDLINE, Embase, CINAHL and Online Contents databases and the keywords 'patient autonomy' in combination with 'nursing', and the Dutch Central Catalogue for material published from 1966 to 2005; (b) ethical and nursing literature was selected on the basis of its identification of positive and negative freedom. We reviewed qualitative empirical research to explore the patients' views of autonomy.

FINDINGS

Negative freedom emphasizes freedom of action and freedom from interference by others. Positive freedom stresses the idea that people should direct their lives according to their personal convictions and individual reasons and goals. The most prominent theories fitting negative freedom are those defining autonomy as self-governance and self-care. Theories fitting positive freedom are those focusing on autonomy in caring, autonomy as identification, autonomy as communication and autonomy as goal achievement. In the empirical literature, two studies centred on patient autonomy in home care, one in nursing home care and three in hospital settings. To achieve autonomy, patients prefer a mixed approach that combines features of negative and positive freedom.

CONCLUSION

Nurses cannot rely exclusively on one model of autonomy to foster patient autonomy. Rather, it requires in-depth knowledge of, and interaction with, patients in the context of each particular nursing encounter because people express their autonomy through particular courses of action.

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.

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.

Results of the pilot study of DIADEM: a comprehensive disease management programme for type 2 diabetes

AIMS

The purpose of the study was to evaluate the feasibility and preliminary clinical effects of the DIADEM disease management programme for type 2 diabetic patients.

METHODS

The study was performed at two test sites (Cardiff, UK: Aachen, Germany) including 137 and 166 patients, respectively. In 16 study centres any patients with type 2 diabetes capable of communicating by phone and able to perform blood pressure, blood glucose or urine glucose self-measurements were included. The maximum programme duration was 6 months at Cardiff and 4 months at Aachen, during which patients were assessed for glycaemic control, cardiovascular risk profile and the presence of complications of diabetes. Data were entered via the internet to a central server.

RESULTS

At entry into the programme the patient group in Cardiff had significantly lower mean age (60.3+/-9.4 years versus 64.9+/-8.7 years, p<0.001) and duration of diabetes (6.1+/-5.7 years versus 7.4+/-7.0 years, p<0.05) than in Aachen, however body mass index (31.6+/-5.2 kg/m(2) versus 29.5+/-4.9 kg/m(2), p<0.01), HbA1c (7.7+/-1.2% versus 7.1+/-1.2%, p<0.001) and systolic blood pressure (138.4+/-15.1 mmHg versus 133.5+/-11.5 mmHg, p<0.001) were significantly higher. In contrast, total cholesterol (4.7+/-1.0 mmol/l versus 5.5+/-1.1 mmol/l, p<0.001) was significantly lower in Cardiff compared to Aachen. Following entry into the programme highly significant improvements in HbA1c (Cardiff from 7.7% to 7.1%, p<0.001; Aachen from 7.2% to 6.8%, p<0.05) and total cholesterol concentrations (Cardiff: 4.66-4.46 mmol/l; Aachen: 5.33-5.15 mmol/l; both p<0.05) were observed. There were no significant changes in blood pressure at either site.

CONCLUSIONS

Intensive diabetes care was delivered to DIADEM patients and relevant and significant improvements in diabetes care were achieved demonstrating that an IT-based diabetes disease management service can improve care for patients with type 2 diabetes.

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.

The Health Technology Assessment-disease management instrument reliably measured methodologic quality of health technology assessments of disease management

OBJECTIVE

Systematic reviews aim to summarize the evidence in a particular topic area, giving attention to the identified methodologic quality of published research. Because research in a specific area may be susceptible to specific biases, it is assumed that the methodologic quality of Health Technology Assessment (HTA) of disease management cannot properly be measured with the existing methodologic quality assessment instruments. The purpose of this study was to describe to what extent existing instruments are useful in assessing the methodologic quality of HTA of disease management.

STUDY DESIGN AND SETTING

An inventory was made of the problems that arise when assessing the methodologic quality of six HTAs of disease management with three different instruments. Based on these findings, a new instrument is proposed and validated.

RESULTS

Problems mainly concern the items related to the study design, criteria for selection and restriction of patients, baseline and outcome measures, blinding of patients and providers, and the description of (co)-interventions.

CONCLUSION

With its more specific characteristics, the HTA-DM addresses the problems mentioned. The HTA-DM is a reliable instrument for methodologic quality assessment of HTA of disease management in comparison with the other three instruments.

Diabetes control and complications: the role of glycated haemoglobin, 25 years on

The long-term complications of diabetes have major consequences for individual subjects and growing healthcare delivery and cost implications for society. Evidence for the benefits of good glycaemic control, as monitored by glycated haemoglobin measurements, has been developed in the 25 years since they were introduced to the point where HbA(1c) assays play central roles in patient management, clinical guidance and audit, and clinical trial design. In this review this evidence is examined and three classes of uncertainty identified that diminish confidence in the effectiveness of these roles for HbA(1c). 1 Analytical variability between different methods for HbA(1c) has restricted the application of clinical targets and this problem has recently been addressed by reference method standardization. There are two approaches to this which result in different HbA(1c) values and this discrepancy needs to be resolved. 2 Biological variability in HbA(1c) values between individuals also restricts its predictive role when applied to populations. The correlations between HbA(1c) measurements and various components of glycaemia (overall, fasting, postprandial) are still uncertain and differences in protein glycation and de-glycation are greater between subjects than often thought. The influence of variability in erythrocyte life span is an area where research is needed, especially in diabetic subjects. 3 Clinical variability is the most important and complex area of uncertainty. A predictive link between HbA(1c) and clinical outcomes is not as clear-cut as often stated. The correlation with the development of microvascular disease is well established in Type 1 diabetes, but in Type 2 subjects (90% of those with diabetes) the evidence that HbA(1c) monitoring is of value in predicting or preventing macrovascular disease is not strong, although it is the major cause of morbidity and early death in this group. It is recommended that, as a matter of urgency, these issues be examined, particularly within the context of self-care in diabetes.

Specialist general practitioners and diabetes clinics in primary care: a qualitative and descriptive evaluation

AIMS

The aim of this study was to evaluate an innovative approach to the provision of primary care-based diabetes services in Bradford, UK. The service model differs from others in comprising 19 clinics which offer a specialist service, intermediate between primary and secondary care, to all patients within the Bradford area.

METHODS

The study included: analysis of referral, attendance and register data; questionnaires to general practitioners (GPs) and specialist clinic providers; qualitative interviews with clinic and other professional staff and patients; and an economic analysis.

RESULTS

The 19 clinics adopt a range of organizational models. In the first 3 1/2 years, 2415 patients were referred. There was a significant reduction in out-patient attendances at hospital, but also a significant increase in overall patient attendances. Specialist clinic patients differed from hospital patients in being older and having had diabetes for longer since diagnosis. Ten of the 14 clinics run by practising GPs attracted more referrals from within their practices than from outside. GPs and patients across the city believed the clinics were valuable, the main benefits being geographical accessibility, availability of specialists in a community setting, short waiting times for first appointments at most clinics, and continuity of staff. Their reservations included a lack of strategic planning in the location of clinics, long waiting times at some clinics, and poor communication at some clinics with referring GPs. The cost of the primary care clinics is similar to hospital clinics.

CONCLUSIONS

This model of specialist primary care services offers an opportunity to develop diabetes services that are convenient to patients, popular with practitioners, and increase capacity. However, the shortcomings as well as the advantages of the model need to be addressed if it is to be implemented elsewhere or for other patient groups.

Nurse-led shared care diabetes projects: lessons from the nurses' viewpoint

This paper explores the experiences of four nurse practitioners specialised in diabetes care, in the development and implementation of two Dutch nurse-led shared care projects to improve quality of care. The focus is on the impeding factors involved. The nurses' views are compared to those of the 38 participating physicians by using instruments of qualitative research. Both nurses and physicians consider the way shared care delivery has been structured as the most impeding factor, particularly downward substitution of care from doctor to nurse. In the end, lessons are drawn for nurses, doctors and managers, to solve the assessed impediments to shared care.

Applying low disease activity criteria using the DAS28 to assess stability in patients with rheumatoid arthritis

OBJECTIVES

To examine whether low disease activity criteria using the disease activity score (DAS28) can be applied to identify a reasonably large number of patients with stable low disease activity of rheumatoid arthritis (RA) over a six month period, with the ultimate intention of including these patients in a substitution based, shared care model. Additionally, to assess the reliability of the DAS28 for selecting patients with stable disease from an outpatient population.

METHODS

Patients regularly seen at the rheumatology outpatient department of the university hospital Maastricht, were invited for assessment of the stability of their RA. The shared care model was intended to provide care to patients with stable, low disease activity of RA by nurse specialists. For this, patients underwent assessments using the DAS28 criteria at entry and three and six months later. Test-retest reliability was assessed for composing measures as well as for the DAS28.

RESULTS

Of the 97 outpatients included, one third (31 patients) did not complete the study. Patients with missing data were older and assessed their disease activity as greater than patients with complete data. Applying the low disease activity criteria to assess stability over a period of six months (DAS28(T0)</=3.2 and DAS28(T6)-DAS28(T0)</=1.2) resulted in identification of 22/56 (39%) patients with stable, low disease activity of RA. A good similarity score (intraclass correlation coefficient=0.82) for the DAS28 was found.

CONCLUSIONS

The low disease activity criteria using the DAS28 can be used to select patients with stable, low disease activity of RA from a rheumatic outpatient population.

Substitution model with central role for nurse specialist is justified in the care for stable type 2 diabetic outpatients

AIM OF THE STUDY

Assessment of effects on quality of care, in terms of patient outcomes, when tasks in the care for outpatients with stable type 2 diabetes are transferred from internist to nurse specialist and from outpatient clinic to general practice.

BACKGROUND

For the management of chronic diseases with a high prevalence and requiring current monitoring, it is suggested that substitution of care may be an appropriate solution to safeguard high quality care.

DESIGN AND METHODS

A 12-month nonequivalent control group design was used. General practitioners (GPs) referring diabetes patients to the University Hospital Maastricht were asked to choose for the traditional model or the nurse specialist model. Informed consent was obtained from patients with stable diabetes type 2 attending these practices. All patients received care according to the model chosen by their GP. Identified outcomes were: clinical status, health status, self-care behaviour, knowledge of diabetes, patient satisfaction, and consultation with care-providers.

RESULTS

In the control group (n=47) no patients were treated with oral hypoglycaemic agents (OHA) only. The control group was compared with an intervention subgroup (n=52) also without patients receiving OHA only. Clinical data were available for all patients. Patients without complete data from questionnaires had better mean concentration of HbA1c than patients with complete data (P=0.004). The traditional care model and the nurse specialist model achieved equal outcomes, while glycaemic control of patients in the nurse specialist model improved (from 8.6% to 8.3%) but deteriorated in the traditional model (from 8.6% to 8.8%; P-value between groups=0.001).

CONCLUSIONS

The model with nurse specialists taking on roles and tasks beyond those traditionally regarded as their remit as well as new ones, is effective for the care of stable diabetic outpatients.
