[Comparison of acute stroke care pathways-A qualitative multicenter study in three referring hospitals of a stroke network]. / Vergleich von Behandlungspfaden beim akuten Schlaganfall ­ eine qualitative multizentrische Studie in drei zuweisenden Kliniken eines Schlaganfallnetzwerkes.

BACKGROUND: In stroke networks, hospitals that do not provide thrombectomy (referring hospitals) refer patients to specialized hospitals (receiving hospitals) for this specific intervention. In order to improve the access and management of thrombectomy, the focus of research needs to be not only on the receiving hospitals but also on the prior stroke care pathways in referring hospitals. OBJECTIVE: The purpose of this study was to investigate the stroke care pathways in different referring hospitals as well as the advantages and disadvantages associated with these pathways. METHODS: A qualitative multicenter study was carried out in three referring hospitals of a stroke network. Stroke care was assessed and analyzed by using non-participant observations and 15 semi-structured interviews with employees in various health professions. RESULTS: The following aspects were reported as advantageous within the stroke care pathways: (1) a structured and personal prenotification of the patient by the emergency medical service (EMS) members; (2) a more efficiently organized teleneurology workflow; (3) the provision of the secondary referral to thrombectomy by the same EMS members of the primary referral and (4) the integration of external neurologists into in-house structures. CONCLUSION: The study provides insights into different stroke care pathways of three different referring hospitals of a stroke network. The results can be used to derive potentials for improvement of other referring hospitals; however, this study is too small to provide reliable information about their potential effectiveness. Future studies should investigate whether implementation of these recommendations actually leads to improvements and under which conditions they are successful. To ensure patient-centeredness, the perspectives of patients and relatives should also be included.

Patient Pathways During Acute in-Hospital Stroke Treatment: A Qualitative Multi-Method Study.

Introduction: Patients experiencing acute ischemic stroke should access treatment as soon as possible to increase their chances for survival without severe disability. Given the increased complexity of stroke treatment from the provider and patient perspective, this study provides an overview of the pathways followed by stroke patients during in-hospital treatment. Methods: This qualitative study combined twenty-seven observations and fifteen staff interviews at a German comprehensive stroke center providing endovascular treatment ("EVT hospital"). Analysis was based on the COMIC Model for the comprehensive evaluation of complex health care interventions and a grounded theory approach. Results: The patient pathways during in-hospital treatment span the phases (1) admission to hospital, (2) receiving recanalization therapies, and (3) in-patient treatment. Before admission to the EVT hospital, interactions between staff members from the EVT hospital and patients take place as part of the telestroke consultations during which the EVT hospital's ED neurologist meets the patient via a video- and audio-based connection. During the second phase, when IVT and/or EVT are provided to the patient, three teams (ED, neuroradiology and ICU team) with direct patient interactions intersect at the angiography suite until mechanical recanalisation treatment ends and the patient is transferred to the SU or ICU. In the third phase, the patients are treated on the SU or ICU and staff members interact with them according to a pre-defined schedule as well as based on individual needs. Discussion: Our results show that most direct staff-patient interactions are focussed within one phase, with a smaller number of interactions extending to other phases, and no professional (group) with direct patient interactions cover more than two phases of the acute stroke pathway. Future research should investigate how the pathways described here are experienced from the patient perspective, including how the organisation of visible care processes may influence patient satisfaction. Findings can be translated to accessible patient information resources as well as input for digitalisation efforts, provider orientation and training.

"But it's a nice compromise" - Qualitative multi-centre study of barriers and facilitators to acute telestroke cooperation in a regional stroke network.

BACKGROUND: Telemedical services can be used to complement on-site services when demand for specialists exceeds supply or when specialists are not evenly distributed across health systems. Using stroke as an example, this study aimed to explore how patients and staff experience telestroke cooperation in a stroke network in Germany. METHODS: We conducted a qualitative multi-method and multi-centre study combining 32 non-participant observations at one hub and four spoke hospitals with 26 semi-structured interviews with hub and spoke staff as well as stroke patients and relatives. Observation protocols and interview transcripts were analysed to identify barriers and facilitators to telestroke cooperation from the perspectives of staff, patients and relatives. RESULTS: In terms of barriers to telestroke cooperation, we found technological problems, providing the treatment for one patient from two sites, competing priorities between telestroke and in-house duties in the spoke hospitals, as well as difficulties in participating in the teleneurological examination via a videoconferencing system for older and disabled patients. In terms of facilitators, we found an overall very positive perception of telestroke provision by patients, good professional relationships within the network, and sharing of neurological expertise to be experienced as helpful for telestroke cooperation. CONCLUSIONS: We recommend better integration of telemedical services into the care pathway, fostering relationships within the network, improved technological support and resources, and more emphasis within networks, in public awareness efforts as well as in academia on the evaluation of telemedical services from the perspectives of patients and relatives, especially older patients and patients with disabilities.

Impact of the coronavirus disease 2019 pandemic on stroke teleconsultations in Germany in the first half of 2020.

BACKGROUND AND PURPOSE: The effects of the coronavirus disease 2019 (COVID-19) pandemic on telemedical care have not been described on a national level. Thus, we investigated the medical stroke treatment situation before, during, and after the first lockdown in Germany. METHODS: In this nationwide, multicenter study, data from 14 telemedical networks including 31 network centers and 155 spoke hospitals covering large parts of Germany were analyzed regarding patients' characteristics, stroke type/severity, and acute stroke treatment. A survey focusing on potential shortcomings of in-hospital and (telemedical) stroke care during the pandemic was conducted. RESULTS: Between January 2018 and June 2020, 67,033 telemedical consultations and 38,895 telemedical stroke consultations were conducted. A significant decline of telemedical (p < 0.001) and telemedical stroke consultations (p < 0.001) during the lockdown in March/April 2020 and a reciprocal increase after relaxation of COVID-19 measures in May/June 2020 were observed. Compared to 2018-2019, neither stroke patients' age (p = 0.38), gender (p = 0.44), nor severity of ischemic stroke (p = 0.32) differed in March/April 2020. Whereas the proportion of ischemic stroke patients for whom endovascular treatment (14.3% vs. 14.6%; p = 0.85) was recommended remained stable, there was a nonsignificant trend toward a lower proportion of recommendation of intravenous thrombolysis during the lockdown (19.0% vs. 22.1%; p = 0.052). Despite the majority of participating network centers treating patients with COVID-19, there were no relevant shortcomings reported regarding in-hospital stroke treatment or telemedical stroke care. CONCLUSIONS: Telemedical stroke care in Germany was able to provide full service despite the COVID-19 pandemic, but telemedical consultations declined abruptly during the lockdown period and normalized after relaxation of COVID-19 measures in Germany.

Differential effects of the SARS-CoV-2 pandemic on patients presenting to a neurological emergency room depending on their triage score in an area with low COVID-19 incidence.

BACKGROUND: We analyzed the effects of the SARS-CoV-2 pandemic on neurologic emergencies, depending on the patients' triage score in a setting with relatively few COVID-19 cases and without lack of resources. METHODS: Consecutive patients of a tertiary care center with a dedicated neurologic emergency room (nER) were analyzed. The time period of the first lockdown in Germany (calendar weeks 12-17, 2020) was retrospectively compared to the corresponding period in 2019 regarding the number of patients presenting to the nER, the number of patients with specific triage scores (Heidelberg Neurological Triage Score), the number of patients with stroke, and the quality of stroke care. RESULTS: A total of 4330 patients were included. Fewer patients presented themselves in 2020 compared to 2019 (median [interquartile range] per week: 134 [118-143] vs. 187 [182-192]; p = 0.015). The median numbers of patients per week with triage 1 (emergent) and 4 (non-urgent) were comparable (51 [43-58] vs. 59 [54-62]; p = 0.132, and 10 [4-16] vs. 16 [7-18]; p = 0.310, respectively).The median number of patients per week declined in categories 2 and 3 in 2020 (41 [37-45] vs. 57 [52-61]; p = 0.004, and 28 [23-35] vs. 61 [52-63]; p = 0.002, respectively. No change was observed in the absolute number of strokes (138 in 2019 and 141 in 2020). Quality metrics of stroke revascularization therapies (symptom-to-door time, door-to-needle time or relative number of therapies) and stroke severity remained constant. CONCLUSION: During the lockdown period in 2020, the number of patients with emergent symptoms remained constant, while fewer patients with urgent symptoms presented to the nER. This may imply behavioral changes in care-seeking behavior.

How to use and assess qualitative research methods.

This paper aims to provide an overview of the use and assessment of qualitative research methods in the health sciences. Qualitative research can be defined as the study of the nature of phenomena and is especially appropriate for answering questions of why something is (not) observed, assessing complex multi-component interventions, and focussing on intervention improvement. The most common methods of data collection are document study, (non-) participant observations, semi-structured interviews and focus groups. For data analysis, field-notes and audio-recordings are transcribed into protocols and transcripts, and coded using qualitative data management software. Criteria such as checklists, reflexivity, sampling strategies, piloting, co-coding, member-checking and stakeholder involvement can be used to enhance and assess the quality of the research conducted. Using qualitative in addition to quantitative designs will equip us with better tools to address a greater range of research problems, and to fill in blind spots in current neurological research and practice.

Factors affecting prehospital delay in rural and urban patients with stroke: a prospective survey-based study in Southwest Germany.

BACKGROUND: Reducing prehospital delay plays an important role in increasing the thrombolysis rate in patients with stroke. Several studies have identified predictors for presentation ≤4.5 h, but few compared these predictors in urban and rural communities. We aimed to identify predictors of timely presentation to the hospital and identify possible differences between the urban and rural populations. METHODS: From January to June 2017, we conducted a prospective survey of patients with stroke admitted to an urban comprehensive stroke centre (CSC) and a rural primary care centre (PCC). Predictors were identified using binary logistical regression. Predictors and patient characteristics were then compared between the CSC and PCC. RESULTS: Overall, 459 patients were included in our study. We identified hesitation before seeking help, awareness of the existence of a time-window, type of admission and having talked about stroke symptoms with friends/relatives who had previously had a stroke as the strongest predictors for presentation to the emergency room ≤4.5 h. Patients admitted to the rural PCC were more hesitant to seek help and less likely to contact emergency services, even though patients had comparable knowledge pertaining to stroke care concepts. CONCLUSIONS: Patients from rural areas were more likely to be hesitant to seek help and contacted the EMS less frequently, despite similar self-awareness of having a stroke. Educational campaigns should focus on addressing these disparities in rural populations. Affected patients should also be encouraged to talk about their symptoms and take part in educational campaigns.

Barriers and Facilitators to Workforce Changes in Integrated Care.

INTRODUCTION: The aim of the study is to investigate the barriers and facilitators to the implementation of workforce changes implemented as part of integrated chronic care interventions. METHODS: We used a qualitative multimethod design that combined expert questionnaires, a systematic literature review, and secondary analysis of two case reports. Twenty-five experts, twenty-one studies and two case reports were included in the study. RESULTS: Most barriers related to problematic delivery structures, health professionals' skills and enthusiasm, IT, funding, culture and cooperation and communication. Most facilitators related to health professionals' motivation and enthusiasm, good delivery structures, communication and cooperation, IT, patients, leadership and senior management. Overall, similar categories of barriers and facilitators were found. DISCUSSION: We recommend that future research focusses on more complex designs including multiple data sources, as these are better able to capture the complexity of interventions such as integrated care. We recommend that health managers and policy-makers should invest in delivery structures and skills and motivation of health professionals to improve the implementation of workforce changes in integrated chronic care interventions. CONCLUSION: The added value of the present study lies in its provision of information on which factors might mitigate the success of an intervention, which helps to prevent premature conclusions of ineffectiveness for complex interventions.

Exploration of workforce changes in integrated chronic care: Findings from an interactive and emergent research design.

INTRODUCTION: Integrated care interventions introduced in response to the increased demand for long-term care entail profound changes to the health workforce. This exploratory study aims to provide an overview of the workforce changes implemented as part of integrated chronic care interventions. METHODS: An interactive and emergent research design was used consisting of a literature review, qualitative expert questionnaires and case reports. We defined integrated care as interventions targeting at least two of the six Chronic Care Model components. Workforce changes were defined as those changes experienced by clinical and non-clinical staff responsible for public and individual health intervention. RESULTS: Seven workforce changes were identified: (1) nurse involvement, (2) multidisciplinary staff, (3) multidisciplinary protocols/pathways, (4) provider training, (5) case manager/care coordinator, (6) team meetings, and (7) new positions. Most interventions included more than one of these workforce changes. CONCLUSION: The results of this study provide detailed insights into the current implementation of workforce changes in integrated care interventions and thereby pave the way for further investigations into the relative effectiveness of different workforce changes within the scope of complex interventions. Advancing knowledge in this area is essential for fostering health systems' capacity to cope with the challenges related to the current demographic and epidemiological trends.

The Development, Description and Appraisal of an Emergent Multimethod Research Design to Study Workforce Changes in Integrated Care Interventions.

INTRODUCTION: In this paper, we provide a detailed and explicit description of the processes and decisions underlying and shaping the emergent multimethod research design of our study on workforce changes in integrated chronic care. THEORY AND METHODS: The study was originally planned as mixed method research consisting of a preliminary literature review and quantitative check of these findings via a Delphi panel. However, when the findings of the literature review were not appropriate for quantitative confirmation, we chose to continue our qualitative exploration of the topic via qualitative questionnaires and secondary analysis of two best practice case reports. RESULTS: The resulting research design is schematically described as an emergent and interactive multimethod design with multiphase combination timing. In doing so, we provide other researchers with a set of theory- and experience-based options to develop their own multimethod research and provide an example for more detailed and structured reporting of emergent designs. CONCLUSION AND DISCUSSION: We argue that the terminology developed for the description of mixed methods designs should also be used for multimethod designs such as the one presented here.

Advancing integrated care and its evaluation by means of a universal typology.

Health systems around the globe implement integrated care interventions to address the Triple Aim of simultaneously improving population health, patient experiences and cost-efficiency. However, the underlying definitions and conceptualisations of integrated care often differ considerably, which makes uniform measurement and comparison difficult. Rather than agreeing on one definition of integrated care, we argue that a universal typology of integrated care interventions should be developed to enable the comparison of interventions that are based on different understandings of integrated care. This universal typology should combine rankable and intangible components with unrankable and tangible sub-components, and be conceptually sound and flexible. The content of the typology should be developed by an international consortium of relevant stakeholders.

Implementation of integrated geriatric care at a German hospital: a case study to understand when and why beneficial outcomes can be achieved.

BACKGROUND: Many health systems have implemented integrated care as an alternative approach to health care delivery that is more appropriate for patients with complex, long-term needs. The objective of this article was to analyse the implementation of integrated care at a German geriatric hospital and explore whether the use of a "context-mechanisms-outcomes"-based model provides insights into when and why beneficial outcomes can be achieved. METHODS: We conducted 15 semi-structured interviews with health professionals employed at the hospital. The data were qualitatively analysed using a "context-mechanisms-outcomes"-based model. Specifically, mechanisms were defined as the different components of the integrated care intervention and categorised according to Wagner's Chronic Care Model (CCM). Context was understood as the setting in which the mechanisms are brought into practice and described by the barriers and facilitators encountered in the implementation process. These were categorised according to the six levels of Grol and Wensing's Implementation Model (IM): innovation, individual professional, patient, social context, organisational context and economic and political context. Outcomes were defined as the effects triggered by mechanisms and context, and categorised according to the six dimensions of quality of care as defined by the World Health Organization, namely effectiveness, efficiency, accessibility, patient-centeredness, equity and safety. RESULTS: The integrated care intervention consisted of three main components: a specific reimbursement system ("early complex geriatric rehabilitation"), multidisciplinary cooperation, and comprehensive geriatric assessments. The inflexibility of the reimbursement system regarding the obligatory number of treatment sessions contributed to over-, under- and misuse of services. Multidisciplinary cooperation was impeded by a high workload, which contributed to waste in workflows. The comprehensive geriatric assessments were complemented with information provided by family members, which contributed to decreased likelihood of adverse events. CONCLUSIONS: We recommend an increased focus on trying to understand how intervention components interact with context factors and, combined, lead to positive and/or negative outcomes.

How to Improve Integrated Care for People with Chronic Conditions: Key Findings from EU FP-7 Project INTEGRATE and Beyond.

BACKGROUND: Political and public health leaders increasingly recognize the need to take urgent action to address the problem of chronic diseases and multi-morbidity. European countries are facing unprecedented demand to find new ways to deliver care to improve patient-centredness and personalization, and to avoid unnecessary time in hospitals. People-centred and integrated care has become a central part of policy initiatives to improve the access, quality, continuity, effectiveness and sustainability of healthcare systems and are thus preconditions for the economic sustainability of the EU health and social care systems. PURPOSE: This study presents an overview of lessons learned and critical success factors to policy making on integrated care based on findings from the EU FP-7 Project Integrate, a literature review, other EU projects with relevance to this study, a number of best practices on integrated care and our own experiences with research and policy making in integrated care at the national and international level. RESULTS: Seven lessons learned and critical success factors to policy making on integrated care were identified. CONCLUSION: The lessons learned and critical success factors to policy making on integrated care show that a comprehensive systems perspective should guide the development of integrated care towards better health practices, education, research and policy.

Context, mechanisms and outcomes of integrated care for diabetes mellitus type 2: a systematic review.

BACKGROUND: Integrated care interventions for chronic conditions can lead to improved outcomes, but it is not clear when and why this is the case. This study aims to answer the following two research questions: First, what are the context, mechanisms and outcomes of integrated care for people with type 2 diabetes? Second, what are the relationships between context, mechanisms and outcomes of integrated care for people with type 2 diabetes? METHODS: A systematic literature search was conducted for the period 2003-2013 in Cochrane and PubMed. Articles were included when they focussed on integrated care and type 2 diabetes, and concerned empirical research analysing the implementation of an intervention. Data extraction was performed using a common data extraction table. The quality of the studies was assessed with the Mixed Methods Appraisal Tool. The CMO model (context + mechanism = outcome) was used to study the relationship between context factors (described by the barriers and facilitators encountered in the implementation process and categorised at the six levels of the Implementation Model), mechanisms (defined as intervention types and described by their number of Chronic Care Model (sub-)components) and outcomes (the intentional and unintentional effects triggered by mechanism and context). RESULTS: Thirty-two studies met the inclusion criteria. Most reported barriers to the implementation process were found at the organisational context level and most facilitators at the social context level. Due to the low number of articles reporting comparable quantitative outcome measures or in-depth qualitative information, it was not possible to make statements about the relationship between context, mechanisms and outcomes. CONCLUSIONS: Efficient resource allocation should entail increased investments at the organisational context level where most barriers are expected to occur. It is likely that investments at the social context level will also help to decrease the development of barriers at the organisational context level, especially by increasing staff involvement and satisfaction. If future research is to adequately inform practice and policy regarding the impact of these efforts on health outcomes, focus on the actual relationships between context, mechanisms and outcomes should be actively incorporated into study designs.

Intervention types and outcomes of integrated care for diabetes mellitus type 2: a systematic review.

RATIONALE, AIMS AND OBJECTIVES: The delivery of integrated care is a priority in many countries' efforts to improve health outcomes for people at risk of or with diabetes. This study aims to provide an overview of the different types of integrated care interventions for type 2 diabetes and to report their outcomes. METHODS: A systematic literature search was conducted in PubMed and Cochrane for the period 2003-2013. Article selection and data extraction were performed independently by three researchers and results were discussed together. The chronic care model (CCM) was used to describe intervention types. RESULTS: Forty-four articles met the inclusion criteria. Most interventions included all CCM components and a variety of sub-components. Most studies reported positive patient, process and health service utilization measures. The information on costs was limited and inconsistent. The low number of articles reporting comparable outcome measures made it difficult to make meaningful statements about an association between intervention type and outcomes. CONCLUSIONS: Future research would benefit from a more uniform understanding of integrated care as well as intermediate outcome measurements that allow for the establishment of a chain of evidence from specific intervention types to specific outcomes achieved. It is expected that such a comprehensive approach will reveal important insights as to which integrated care intervention types and settings are most conducive to successful implementation and would thereby be of relevance to policy makers and practitioners involved in the financing, management and delivery of integrated care.

Great Expectations: The Implementation of Integrated Care and Its Contribution to Improved Outcomes for People with Chronic Conditions.

There are great expectations regarding the potential contribution of integrated care interventions to improved outcomes, but so far the evidence is mixed. In this dissertation, we focussed on why, when and how some integrated care interventions contribute to improved outcomes, while others do not. To this purpose, we developed the COMIC Model for studying the Context, Outcomes and Mechanisms of Integrated Care interventions. Evaluations that make use of the COMIC Model take into account the context in which an intervention is implemented and can thereby provide insights into why an intervention does (not) work and how the intervention and/or the context can be changed to achieve improved outcomes.

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

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

Implementation of integrated care for type 2 diabetes: a protocol for mixed methods research.

INTRODUCTION: While integrated care for diabetes mellitus type 2 has achieved good results in terms of intermediate clinical and process outcomes, the evidence-based knowledge on its implementation is scarce, and insights generalisable to other settings therefore remain limited. OBJECTIVE: This study protocol provides a description of the design and methodology of a mixed methods study on the implementation of integrated care for type 2 diabetes. The aim of the proposed research is to investigate the mechanisms by which and the context in which integrated care for type 2 diabetes has been implemented, which outcomes have been achieved and how the context and mechanisms have affected the outcomes. METHODS: This article describes a convergent parallel mixed methods research design, including a systematic literature review on the implementation of integrated care for type 2 diabetes as well as a case study on two Dutch best practices on integrated care for type 2 diabetes. DISCUSSION: The implementation of integrated care for diabetes type 2 is an under-researched area. Insights from this study could be applied to other settings as well as other chronic conditions to strengthen the evidence on the implementation of integrated care.
