Instruments to assess integrated care: a systematic review

INTRODUCTION

Although several measurement instruments have been developed to measure the level of integrated health care delivery, no standardised, validated instrument exists covering all aspects of integrated care. The purpose of this review is to identify the instruments concerning how to measure the level of integration across health-care sectors and to assess and evaluate the organisational elements within the instruments identified.

METHODS

An extensive, systematic literature review in PubMed, CINAHL, PsycINFO, Cochrane Library, Web of Science for the years 1980-2011. Selected abstracts were independently reviewed by two investigators.

RESULTS

We identified 23 measurement instruments and, within these, eight organisational elements were found. No measurement instrument covered all organisational elements, but almost all studies include well-defined structural and process aspects and six include cultural aspects; 14 explicitly stated using a theoretical framework.

CONCLUSION AND DISCUSSION

This review did not identify any measurement instrument covering all aspects of integrated care. Further, a lack of uniform use of the eight organisational elements across the studies was prevalent. It is uncertain whether development of a single 'all-inclusive' model for assessing integrated care is desirable. We emphasise the continuing need for validated instruments embedded in theoretical contexts.

Evaluating chronic disease management in real-world settings in six European countries: Lessons from the collaborative DISMEVAL project

Objective

To describe the interventions, research methods and main findings of the international DISMEVAL project, in which the “real-world” impact of exemplary European disease management approaches was investigated in six countries using advanced analytic techniques.

Design

Across countries, the project captured a wide range of disease management strategies and settings; approaches to evaluation varied per country, but included, among others, difference-in-differences analysis and regression discontinuity analysis.

Setting

Austria, Denmark, France, Germany, The Netherlands, and Spain.

Participants

Health care providers and/or statutory insurance funds providing routine data from their disease management interventions, mostly retrospectively.

Intervention(s)

This study did not carry out an intervention but evaluated the impact of existing disease management interventions implemented in European care settings.

Main outcome measure(s)

Outcome measures were largely dependent on available routine data, but could concern health care structures, processes, and outcomes.

Results

Data covering 10 to 36 months were gathered concerning more than 154,000 patients with three conditions. The analyses demonstrated considerable positive effects of disease management on process quality (Austria, Germany), but no more than moderate improvements in intermediate health outcomes (Austria, France, Netherlands, Spain) or disease progression (Denmark) in intervention patients, where possible compared with a matched control group.

Conclusions

Assessing the “real-world” impact of chronic disease management remains a challenge. In settings where randomization is not possible and/or desirable, routine health care performance data can provide a valuable resource for practice-based evaluations using advanced analytic techniques.

The effect of rehabilitation on health-care utilisation in COPD patients in Copenhagen

INTRODUCTION

The Integrated Rehabilitation Programme for Chronic Conditions project (SIKS) implemented rehabilitation programmes for people with four chronic conditions in the local area within the Municipality of Copenhagen.

OBJECTIVES

The objective of this study was to evaluate the impact of rehabilitation on health-care utilisation in chronic obstructive pulmonary disease (COPD) patients as a subgroup of SIKS.

METHODS

For the analyses, data from Danish National Registers' were obtained. The following outcomes were analysed: (i) COPD hospital admissions, (ii) COPD bed days, (iii) COPD outpatient visits, (iv) COPD emergency room visits, (v) general practitioner visits, (vi) specialist visits, and (vii) COPD specific medication. The rehabilitation group consisted of 118 patients who completed the programme. The control group consisted of 236 COPD patients in Copenhagen who did not undergo rehabilitation and were matched with the intervention group according to propensity score calculated on the basis of patient socio-demographic characteristics and health-care utilisation pattern in 2 years prior to the rehabilitation programme. The effect was assessed by applying the principle of difference-in-difference analysis.

RESULTS

Compared with their matched controls, the patients participating in the rehabilitation programme showed a statistically significantly smaller increase in hospital admissions, bed days and outpatient visits.

CONCLUSIONS

The study provides the policy decision makers in the Municipality of Copenhagen with an assessment of the effect of a real-life intervention. It shows that the pulmonary rehabilitation programme introduced had the anticipated effects on health-care utilisation. The study also suggests that the methods used for evaluation were appropriate.

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.

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.

Social organization of self-management support of persons with diabetes: a health systems comparison

OBJECTIVE

Identify important organizational elements for providing self-management support (SMS).

DESIGN

Semi-structured qualitative interviews conducted in two healthcare systems.

SETTING

Kaiser Permanente Northern California and the Danish Health Care System.

SUBJECTS

36 managers and healthcare professionals in the two healthcare systems.

MAIN OUTCOME MEASURES

Elements important to providing self-management support to persons with diabetes.

RESULTS

Healthcare professionals' provision of SMS was influenced by healthcare system organization and their perceptions of SMS, the capability and responsibility of healthcare systems, and their roles in the healthcare organization. Enabling factors for providing SMS included: strong leadership; aligned incentives; use of an integrated health information technology (HIT) system; multidisciplinary healthcare provider teams; ongoing training for healthcare professionals; outreach; and quality goals. Barriers to providing SMS included lack of collaboration between providers and skeptical attitudes towards prevention and outreach.

CONCLUSIONS AND IMPLICATIONS

Implementation of SMS can be improved by an understanding of the elements that enhance its provision: (1) initiatives seeking to improve collaboration and integration between providers; (2) implementation of an integrated HIT system; and (3) ongoing training of healthcare professionals.

Self-management support to people with type 2 diabetes - a comparative study of Kaiser Permanente and the Danish Healthcare System

Background

Self-management support is considered to be an essential part of diabetes care. However, the implementation of self-management support within healthcare settings has appeared to be challenging and there is increased interest in “real world” best practice examples to guide policy efforts. In order to explore how different approaches to diabetes care and differences in management structure influence the provision of SMS we selected two healthcare systems that have shown to be comparable in terms of budget, benefits and entitlements. We compared the extent of SMS provided and the self-management behaviors of people living with diabetes in Kaiser Permanente (KP) and the Danish Healthcare System (DHS).

Methods

Self-administered questionnaires were used to collect data from a random sample of 2,536 individuals with DM from KP and the DHS in 2006–2007 to compare the level of SMS provided in the two systems and identify disparities associated with educational attainment. The response rates were 75 % in the DHS and 56 % in KP. After adjusting for gender, age, educational level, and HbA1c level, multiple linear regression analyses determined the level of SMS provided and identified disparities associated with educational attainment.

Results

Receipt of SMS varied substantially between the two systems. More people with diabetes in KP reported receiving all types of SMS and use of SMS tools compared to the DHS (p < .0001). Less than half of all respondents reported taking diabetes medication as prescribed and following national guidelines for exercise.

Conclusions

Despite better SMS support in KP compared to the DHS, self-management remains an under-supported area of care for people receiving care for diabetes in the two health systems. Our study thereby suggests opportunity for improvements especially within the Danish healthcare system and systems adopting similar SMS support strategies.

Predictors of effects of lifestyle intervention on diabetes mellitus type 2 patients

The main aim of the study was to identify predictors of the effects of lifestyle intervention on diabetes mellitus type 2 patients by means of multivariate analysis. Data from a previously published randomised clinical trial, which compared the effects of a rehabilitation programme including standardised education and physical training sessions in the municipality's health care centre with the same duration of individual counseling in the diabetes outpatient clinic, were used. Data from 143 diabetes patients were analysed. The merged lifestyle intervention resulted in statistically significant improvements in patients' systolic blood pressure, waist circumference, exercise capacity, glycaemic control, and some aspects of general health-related quality of life. The linear multivariate regression models explained 45% to 80% of the variance in these improvements. The baseline outcomes in accordance to the logic of the regression to the mean phenomenon were the only statistically significant and robust predictors in all regression models. These results are important from a clinical point of view as they highlight the more urgent need for and better outcomes following lifestyle intervention for those patients who have worse general and disease-specific health.

Pulmonary rehabilitation for moderate COPD (GOLD 2)--does it have an effect?

BACKGROUND

Although pulmonary rehabilitation is an integrated part of standard care in patients with severe COPD, it is uncertain whether those with less severe COPD benefit from such treatment. The aim of the present survey was to evaluate the effect of rehabilitation in patients with moderate COPD and to determine their willingness to participate in rehabilitation.

MATERIAL AND METHODS

In a single-centre, randomized, placebo-controlled, unblinded clinical trial, participants comprised 61 of 133 referred subjects with moderate COPD. Of the 61 participants, 35 were randomized to receive rehabilitation and 26 subjects to receive standard COPD care from their GP. After randomization 19 subjects dropped out.

RESULTS

Effects of physical training were seen during the period of intervention. Compared with those receiving standard GP care, those receiving rehabilitation showed improvements in walking distance and leg strength as well as improvements in quality of life; however, the effect was temporary, and at 18 months' follow-up there was no significant difference between the groups. Only 61 subjects of the referred group of 133 with moderate COPD accepted the offer of rehabilitation.

CONCLUSION

Although an effect was found of pulmonary rehabilitation in subjects with moderate COPD, it disappeared over 18 months. Only a minority of patients with moderate COPD referred for rehabilitation accepted and completed the treatment offer.

Identifying organisational principles and management practices important to the quality of health care services for chronic conditions

BACKGROUND

The quality of health care services offered to people suffering from chronic diseases often fails to meet standards in Denmark or internationally. The population consisting of people with chronic diseases is large and accounts for about 70% of total health care expenses. Given that resources are limited, it is necessary to identify efficient methods to improve the quality of care. Comparing health care systems is a well-known method for identifying new knowledge regarding, for instance, organisational methods and principles. Kaiser Permanente (KP), an integrated health care delivery system in the U.S., is recognized as providing high-quality chronic care; to some extent, this is due to KP's implementation of the chronic care model (CCM). This model recommends a range of evidence-based management practices that support the implementation of evidence-based medicine. However, it is not clear which management practices in the CCM are most efficient and in what combinations. In addition, financial incentives and public reporting of performance are often considered effective at improving the quality of health care services, but this has not yet been definitively proved.

AIM

The aim of this dissertation is to describe the effect of determinants, such as organisational structures and management practices including two selected incentives, on the quality of care in chronic diseases. The dissertation is based on four studies with the following purposes: 1) macro- or healthcare system-level identification of organisational structures and principles that affect the quality of health care services, based on a comparison of KP and the Danish health care system; 2) meso- or organisation-level identification of management practices with positive effects on screening rates for hemoglobin A1c and lipid profile in diabetes; 3) evaluation of the effect of the CCM on quality of health care services and continuity of care in a Danish setting; 4) micro- or practice-level evaluation of the effect of financial incentives and public performance reporting on the behaviour of professionals and quality of care.

METHODS AND RESULTS

Using secondary data, KP and the Danish health care system were compared in terms of six central dimensions: population, health care professionals, health care organisations, utilization patterns, quality measurements, and costs. Differences existed between the two systems on all dimensions, complicating the interpretation of findings. For instance, observed differences might be due to similar tendencies in the two health care systems that were observed at different times, rather than true structural differences. The expenses in the two health care systems were corrected for differences in the populations served and the purchasing power of currencies. However, no validated methods existed to correct for observed differences in case-mixes of chronic conditions. Data from a population of about half a million patients with diabetes in a large U.S. integrated health care delivery system affiliated with 41 medical centers employing 15 different CCM management practices was the basis for identifying effective management practices. Through the use of statistical modelling, the management practice of provider alerts was identified as most effective for promoting screening for hemoglobin A1c and lipid profile. The CCM was used as a framework for implementing four rehabilitation programs. The model promoted continuity of care and quality of health care services. New management practices were developed in the study, and known practices were further developed. However, the observational nature of the study limited the generalisability of the findings. In a structured literature survey focusing on the effect of financial incentives and public performance reporting on the quality of health care services, few studies documenting an effect were identified. The results varied, and important program aspects or contextual variables were often omitted. A model describing the effects of the two incentives on the conduct of health care professionals and their interaction with the organisations in which they serve was developed.

CONCLUSION

On the macro-level, organisational differences between KP and the Danish health care system related to the primary care sectors, utilization patterns, and the quality of health care services, supporting a hypothesis that KP's focus on primary care is a beneficial form of organisation. On the meso-level, use of the CCM improved quality of health care services, but the effect is complicated and context dependent. The CCM was found to be useful in the Danish health care system, and the model was also further developed in a Danish setting. On the micro-level, quality was improved by financial incentives and disclosure in a complex interplay with other central factors in the work environment of health care professionals.

Health-related quality of life and self-related health in patients with type 2 diabetes: effects of group-based rehabilitation versus individual counselling

Background

Type 2 diabetes can seriously affect patients' health-related quality of life and their self-rated health. Most often, evaluation of diabetes interventions assess effects on glycemic control with little consideration of quality of life. The aim of the current study was to study the effectiveness of group-based rehabilitation versus individual counselling on health-related quality of life (HRQOL) and self-rated health in type 2 diabetes patients.

Methods

We randomised 143 type 2 diabetes patients to either a six-month multidisciplinary group-based rehabilitation programme including patient education, supervised exercise and a cooking-course or a six-month individual counselling programme. HRQOL was measured by Medical Outcomes Study Short Form 36-item Health Survey (SF-36) and self-rated health was measured by Diabetes Symptom Checklist - Revised (DCS-R).

Results

In both groups, the lowest estimated mean scores of the SF36 questionnaire at baseline were "vitality" and "general health". There were no significant differences in the change of any item between the two groups after the six-month intervention period. However, vitality-score increased 5.2 points (p = 0.12) within the rehabilitation group and 5.6 points (p = 0.03) points among individual counselling participants.

In both groups, the highest estimated mean scores of the DSC-R questionnaire at baseline were "Fatigue" and "Hyperglycaemia". Hyperglycaemic and hypoglycaemic distress decreased significantly after individual counselling than after group-based rehabilitation (difference -0.3 points, p = 0.04). No between-group differences occurred for any other items. However, fatigue distress decreased 0.40 points within the rehabilitation group (p = 0.01) and 0.34 points within the individual counselling group (p < 0.01). In the rehabilitation group cardiovascular distress decreased 0.25 points (p = 0.01).

Conclusions

A group-based rehabilitation programme did not improve health-related quality of life and self-rated health more than an individual counselling programme. In fact, the individual group experienced a significant relief in hyper- and hypoglycaemic distress compared with the rehabilitation group.

However, the positive findings of several items in both groups indicate that lifestyle intervention is an important part of the management of type 2 diabetes patients.

Effect of a group-based rehabilitation programme on glycaemic control and cardiovascular risk factors in type 2 diabetes patients: the Copenhagen Type 2 Diabetes Rehabilitation Project

OBJECTIVE

To compare the effectiveness of a group-based rehabilitation programme with an individual counselling programme at improving glycaemic control and cardiovascular risk factors among patients with type 2 diabetes.

METHODS

We randomised 143 adult type 2 diabetes patients to either a 6-month multidisciplinary group-based rehabilitation programme or a 6-month individual counselling programme. Outcome measures included glycated haemoglobin (HbA(1c)), blood pressure, lipid profile, weight, and waist circumference.

RESULTS

Mean HbA(1c) decreased 0.3%-point (95% confidence interval [CI] = -0.5, -0.1) in the rehabilitation group and 0.6%-point (95% CI = -0.8, -0.4) among individual counselling participants (p<0.05). Within both groups, equal reductions occurred in body weight, waist circumference, systolic blood pressure and diastolic blood pressure, but no significant between-group differences between occurred for any of the cardiovascular outcomes. The group-based rehabilitation programme consumed twice as many personnel resources.

CONCLUSION

The group-based rehabilitation programme resulted in changes in glycaemic control and cardiovascular risk factor reduction that were equivalent or inferior to those of an individual counselling programme.

PRACTICE IMPLICATIONS

The group-based rehabilitation programme, tested in the current design, did not offer additionally improved outcomes and consumed more personnel resources than the individual counselling programme; its broad implementation is not supported by this study.

Effective population management practices in diabetes care - an observational study

BACKGROUND

Ensuring that evidence based medicine reaches patients with diabetes in the US and internationally is challenging. The chronic care model includes evidence based management practices which support evidence based care. However, despite numerous studies, it is unclear which practices are most effective. Few studies assess the effect of simultaneous practices implemented to varying degrees. The present study evaluates the effect of fifteen practices applied concurrently and takes variation in implementation levels into account while assessing the impact of diabetes care management practices on glycemic and lipid monitoring.

METHODS

Fifteen management practices were identified. Implementation levels of the practices in 41 medical centres caring for 553,556 adults with diabetes were assessed from structured interviews with key informants. Stepwise logistic regression models with management practices as explanatory variables and glycemic and lipid monitoring as outcome variables were used to identify the diabetes care practices most associated with high performance.

RESULTS

Of the 15 practices studied, only provider alerts were significantly associated with higher glycemic and lipid monitoring rates. The odds ratio for glycemic monitoring was 4.07 (p < 0.00001); the odds ratio for lipid monitoring was 1.63 (p < 0.006). Weaker associations were found between action plans and glycemic monitoring (odds ratio = 1.44; p < 0.03) and between guideline distribution and training and lipid monitoring (odds ratio = 1.46; p < 0.03). The covariates of gender, age, cardiac disease and depression significantly affected monitoring rates.

CONCLUSIONS

Of fifteen diabetes care management practices, our data indicate that high performance is most associated with provider alerts and more weakly associated with action plans and with guideline distribution and training. Lack of convergence in the literature on effective care management practices suggests that factors contributing to high performance may be highly context-dependent or that the factors involved may be too numerous or their implementation too nuanced to be reliably identified in observational studies.

Early detection of COPD in primary care--the Copenhagen COPD Screening Project

BACKGROUND

Chronic Obstructive Pulmonary Disease (COPD) is among the leading causes of death in the world, and further increases in the prevalence and mortality are predicted. Delay in diagnosing COPD appears frequently even though current consensus guidelines emphasize the importance of early detection of the disease. The aim of the present study is to evaluate the effectiveness of a screening programme in general practice.

METHODS/DESIGN

Subjects aged 65 years and older registered with a General Practitioner (GP) in the eastern Copenhagen will receive a written invitation and a simple questionnaire focusing on risk factors and symptoms of COPD. Subjects who meet the following criteria will be encouraged to undergo spirometric testing at their GP: current smokers, former smokers, and subjects with no smoking history but who have dyspnea and/or chronic cough with sputum.

DISCUSSION

The Copenhagen COPD Screening Project evaluates the effectiveness of a two-stage screening program for COPD in general practice and provides important information on how to organize early detection of COPD in general practice in the future.

Is the Kaiser Permanente model superior in terms of clinical integration?: a comparative study of Kaiser Permanente, Northern California and the Danish healthcare system

BACKGROUND

Integration of medical care across clinicians and settings could enhance the quality of care for patients. To date, there is limited data on the levels of integration in practice. Our objective was to compare primary care clinicians' perceptions of clinical integration and three sub-aspects in two healthcare systems: Kaiser Permanente, Northern California (KPNC) and the Danish healthcare system (DHS). Further, we examined the associations between specific organizational factors and clinical integration within each system.

METHODS

Comparable questionnaires were sent to a random sample of primary care clinicians in KPNC (n = 1103) and general practitioners in DHS (n = 700). Data were analysed using multiple logistic regression models.

RESULTS

More clinicians in KPNC perceived to be part of a clinical integrated environment than did general practitioners in the DHS (OR = 3.06, 95% CI: 2.28, 4.12). Further, more KPNC clinicians reported timeliness of information transfer (OR = 2.25, 95% CI: 1.62, 3.13), agreement on roles and responsibilities (OR = 1.79, 95% CI: 1.30, 2.47) and established coordination mechanisms in place to ensure effective handoffs (OR = 6.80, 95% CI: 4.60, 10.06). None of the considered organizational factors in the sub-country analysis explained a substantial proportion of the variation in clinical integration.

CONCLUSIONS

More primary care clinicians in KPNC reported clinical integration than did general practitioners in the DHS. Focused measures of clinical integration are needed to develop the field of clinical integration and to create the scientific foundation to guide managers searching for evidence based approaches.

Lifestyle intervention for type 2 diabetes patients: trial protocol of The Copenhagen Type 2 Diabetes Rehabilitation Project

BACKGROUND

Current guidelines recommend education, physical activity and changes in diet for type 2 diabetes patients, yet the composition and organization of non-pharmacological care are still controversial. Therefore, it is very important that programmes aiming to improve non-pharmacological treatment of type 2 diabetes are developed and evaluated. The Copenhagen Type 2 Diabetes Rehabilitation Project aims to evaluate the effectiveness of a new group-based lifestyle rehabilitation programme in a Health Care Centre in primary care.

METHODS/DESIGN

The group-based diabetes rehabilitation programme consists of empowerment-based education, supervised exercise and dietary intervention. The effectiveness of this multi-disciplinary intervention is compared with conventional individual counselling in a Diabetes Outpatient Clinic and evaluated in a prospective and randomized controlled trial. During the recruitment period of 18 months 180 type 2 diabetes patients will be randomized to the intervention group and the control group. Effects on glycaemic control, quality of life, self-rated diabetes symptoms, body composition, blood pressure, lipids, insulin resistance, beta-cell function and physical fitness will be examined after 6, 12 and 24 months.

DISCUSSION

The Copenhagen Type 2 Diabetes Rehabilitation Project evaluates a multi-disciplinary non-pharmacological intervention programme in a primary care setting and provides important information about how to organize non-pharmacological care for type 2 diabetes patients.

A retrospective analysis of health systems in Denmark and Kaiser Permanente

Background

To inform Danish health care reform efforts, we compared health care system inputs and performance and assessed the usefulness of these comparisons for informing policy.

Methods

Retrospective analysis of secondary data in the Danish Health Care System (DHS) with 5.3 million citizens and the Kaiser Permanente integrated delivery system (KP) with 6.1 million members in California. We used secondary data to compare population characteristics, professional staff, delivery structure, utilisation and quality measures, and direct costs. We adjusted the cost data to increase comparability.

Results

A higher percentage of KP patients had chronic conditions than did patients in the DHS: 6.3% vs. 2.8% (diabetes) and 19% vs. 8.5% (hypertension), respectively. KP had fewer total physicians and staff compared to DHS, with134 physicians/100,000 individuals versus 311 physicians/100,000 individuals. KP physicians are salaried employees; in contrast, DHS primary care physicians own and run their practices, remunerated by a mixture of capitation and fee-for-service payments, while most specialists are employed at largely public hospitals. Hospitalisation rates and lengths of stay (LOS) were lower in KP, with mean acute admission LOS of 3.9 days versus 6.0 days in the DHS, and, for stroke admissions, 4.2 days versus 23 days. Screening rates also differed: 93% of KP members with diabetes received retinal screening; only 46% of patients in the DHS with diabetes did. Per capita operating expenditures were PPP$1,951 (KP) and PPP $1,845 (DHS).

Conclusion

Compared to the DHS, KP had a population with more documented disease and higher operating costs, while employing fewer physicians and resources like hospital beds. Observed quality measures also appear higher in KP. However, simple comparisons between health care systems may have limited value without detailed information on mechanisms underlying differences or identifying translatable care improvement strategies. We suggest items for more in-depth analyses that could improve the interpretability of findings and help identify lessons that can be transferred.

An international review of projects on hospital performance assessment

BACKGROUND

Assessing the quality of health care has become increasingly important in health care in response to growing demands from purchasers, providers, clinicians and the public. Given the increase in projects and programs to assess performance in health care in the last 15 years, the purpose of this paper is to review current indicator projects for hospital performance assessment and compare them to the Performance Assessment Tool for Quality Improvement in Hospitals (PATH), an initiative by the WHO Regional Office for Europe.

METHODOLOGY

We identified current indicator projects through a systematic literature search and through contact with experts. Using an inductive approach based on a review of the literature, we identified 10 criteria for the comparison of indicator projects. We extracted data and contacted the coordinators of each indicator project to validate this information. In addition, we carried out interviews with coordinators to gather additional information on the evaluation of the respective projects.

RESULTS

We included 11 projects that appear to have adopted a common methodology for the design and selection of indicators; however, major differences exist with regard to the philosophy, scope and coverage of the projects. This relates in particular to criteria such as participation, disclosure of results and dimensions of hospital performance assessed.

CONCLUSION

Hospital performance assessment projects have become common worldwide, and initiatives such as the WHO PATH project need to be well coordinated with existing projects. Our review raised questions regarding the impact of hospital performance assessment that should be pursued in further research.

A behavioral model of clinician responses to incentives to improve quality

The use of pay for performance (P4P) and public reporting of performance (PR) in health care is increasing rapidly worldwide. The rationale for P4P and PR comes from experience in other industries and from theories about incentive use from psychology, economics, and organizational behavior. This paper reviews the major themes from this prior research and considers how they might be applied to health care. The resulting conceptual model addresses the dual nature (combining direct financial and reputational incentives) of the initiatives many policymakers are pursuing. It also includes explicit recognition of the key contextual factors (at the levels of the markets and the provider organization) and provider and patient characteristics that can enhance or mitigate response to incentives. Evaluation of the existing literature (through June 2005) about incentive use in health care in light of the conceptual model highlights important weaknesses in the way that trials have been reported to date and suggests future research topics.

[Accreditation of hospitals. A review of international experiences]

Internationally, there is solid experience on accreditation. Accreditation in the present paper is described in the form that is used in the three biggest and oldest organisations, The Joint Commission on Accreditation of Healthcare Organization (JCAHO), The Canadian Council on Health Services Accreditation (CCHSA), and The Australian Council on Healthcare (ACHS). Common elements in the organisations are standards, indicators, surveyors, surveys, accreditation report, and end result. The development in the three organisations has been different. However, the establishment of The International Society for Quality in Health Care (ISQua) and The Agenda for Leadership in Programs in Healthcare Accreditation (ALPHA) programme has motivated increasing comparability. The fact that association between accreditation and quality in patient care has not been demonstrated is a weak point. However, standards in the accreditation organisations require the use of clinical guidelines in order to increase the quality of patient care. From the "Health Policy Report 2002" it appears that external assessment in the form of accreditation is going to be a reality in the Danish healthcare sector. Hospitals of all counties and within The Copenhagen Hospital Corporation must undergo accreditation before the year 2006.

[Clinical indicators and quality databases--a review]

This review states the work which has been done in Denmark on clinical indicators and large databases containing clinical data with nationwide coverage. The aim of the work was to obtain valid and reliable information on clinical quality to be used by clinicians, leaders, and the public. Nationally we have: 1) The needed experience related to identification and development of clinical indicators and construction of databases. 2) The necessary partners (scientific societies, hospital owners, primary care sector, and health authorities) are motivated and involved in a collaborative organisation. Nationally we lack: 1) Experience with implementation and use of clinical indicators. 2) An overview of the needed investments to ensure coverage of all important diseases, continuity in patient care, and improvement of the existing databases. 3) Fully integrated information systems.
