Accuracy of urgency allocation in patients with shortness of breath calling out-of-hours primary care: a cross-sectional study.

BACKGROUND: In out-of-hours primary care (OHS-PC), semi-automatic decision support tools are often used during telephone triage. In the Netherlands, the Netherlands Triage Standard (NTS) is used. The NTS is mainly expert-based and evidence on the diagnostic accuracy of the NTS' urgency allocation against clinically relevant outcomes for patients calling with shortness of breath (SOB) is lacking. METHODS: We included data from adults (≥18 years) who contacted two large Dutch OHS-PC centres for SOB between 1 September 2020 and 31 August 2021 and whose follow-up data about final diagnosis could be retrieved from their own general practitioner (GP). The diagnostic accuracy (sensitivity and specificity with corresponding 95% confidence intervals (CI)) of the NTS' urgency levels (high (U1/U2) versus low (U3/U4/U5) and 'final' urgency levels (including overruling of the urgency by triage nurses or supervising general practitioners (GPs)) was determined with life-threatening events (LTEs) as the reference. LTEs included, amongst others, acute coronary syndrome, pulmonary embolism, acute heart failure and severe pneumonia. RESULTS: Out of 2012 eligible triage calls, we could include 1833 adults with SOB who called the OHS-PC, mean age 53.3 (SD 21.5) years, 55.5% female, and 16.6% showed to have had a LTE. Most often severe COVID-19 infection (6.0%), acute heart failure (2.6%), severe COPD exacerbation (2.1%) or severe pneumonia (1.9%). The NTS urgency level had a sensitivity of 0.56 (95% CI 0.50-0.61) and specificity of 0.61 (95% CI 0.58-0.63). Overruling of the NTS' urgency allocation by triage nurses and/or supervising GPs did not impact sensitivity (0.56 vs. 0.54, p = 0.458) but slightly improved specificity (0.61 vs. 0.65, p < 0.001). CONCLUSIONS: The semi-automatic decision support tool NTS performs poorly with respect to safety (sensitivity) and efficiency (specificity) of urgency allocation in adults calling Dutch OHS-PC with SOB. There is room for improvement of telephone triage in patients calling OHS-PC with SOB. TRIAL REGISTRATION: The Netherlands Trial Register, number: NL9682 .

Interprofessional education for healthcare professionals. A BEME realist review of what works, why, for whom and in what circumstances in undergraduate health sciences education: BEME Guide No. 83.

AIM: To provide an evidence-informed program theory (PT) for Interprofessional Education (IPE) that adds to the knowledge base of how IPE in undergraduate health sciences education works. METHODS: We undertook a realist review of the literature and synthesis of the evidence combined with stakeholder experience. Our initial program theory (IPT), built around development, delivery and evaluation of IPE interventions, was tested and refined following an in-depth search of the literature and consultation with stakeholders. The literature (2010-2022) was selected based on the realist criteria of relevance and rigor, as well as on conceptual richness of the studies. RESULTS: Our PT is built upon 124 CMOs (Context of IPE interventions, Mechanisms that fired within that context, and IPE Outcomes), from 58 studies. Our PT comprises an array of elements found in the Context, including traits and behavioral displays of students and facilitators, and discusses four Mechanisms (feeling responsible, feeling enthusiastic/excited, feeling safe to take risks, and feeling ready), which are likely to lead to outcomes related to the Interprofessional Education Collaborative (sub)competencies. DISCUSSION: Results were linked to learning theories to further build our understanding. The PT can serve as a guide for the development, delivery, and evaluation of IPE interventions.

Displaying concerns within telephone triage conversations of callers with chest discomfort in out-of-hours primary care: A conversation analytic study.

OBJECTIVES: In primary care out of hours service (OHS-PC), triage nurses ask questions to assign urgency level for medical assessment. A semi-automatic decision tool (the Netherlands Triage Standard, NTS) facilitates triage nurses with key questions, but does not leave much room for paying attention to callers' concerns. We wanted to understand how callers with chest pain formulate their concerns and are helped further during telephone triage. METHODS: We conducted a conversation analytic study of 68 triage calls from callers with chest discomfort who contacted OHS-PC of which we selected 35 transcripts in which concerns were raised. We analyzed expressions of concerns and the corresponding triage nurse response. RESULTS: Due to the task-oriented nature of the NTS, callers' concerns were overlooked. For callers, however, discussing concerns was relevant, stressed by the finding that the majority of callers with chest discomfort expressed concerns. CONCLUSIONS: Interactional difficulties in concern-related discussions arised directly after expressed concerns if not handled adequately, or during the switch to the counseling phase. PRACTICE IMPLICATIONS: When callers display concerns during telephone triage, we recommend triage nurses to explore them briefly and then return to the sequence of tasks described in the NTS-assisted triage process.

A novel approach for assessing bias during team-based clinical decision-making.

Many clinical processes include multidisciplinary group decision-making, yet few methods exist to evaluate the presence of implicit bias during this collective process. Implicit bias negatively impacts the equitable delivery of evidence-based interventions and ultimately patient outcomes. Since implicit bias can be difficult to assess, novel approaches are required to detect and analyze this elusive phenomenon. In this paper, we describe how the de Groot Critically Reflective Diagnoses Protocol (DCRDP) can be used as a data analysis tool to evaluate group dynamics as an essential foundation for exploring how interactions can bias collective clinical decision-making. The DCRDP includes 6 distinct criteria: challenging groupthink, critical opinion sharing, research utilization, openness to mistakes, asking and giving feedback, and experimentation. Based on the strength and frequency of codes in the form of exemplar quotes, each criterion was given a numerical score of 1-4 with 1 representing teams that are interactive, reflective, higher functioning, and more equitable. When applied as a coding scheme to transcripts of recorded decision-making meetings, the DCRDP was revealed as a practical tool for examining group decision-making bias. It can be adapted to a variety of clinical, educational, and other professional settings as an impetus for recognizing the presence of team-based bias, engaging in reflexivity, informing the design and testing of implementation strategies, and monitoring long-term outcomes to promote more equitable decision-making processes in healthcare.

A Changing Landscape for Lifelong Learning in Health Globally.

On 25 July 2022, the Continuing Professional Development (CPD) Special Interest Group of the Association for Medical Education in Europe came together to open up discussions during a live webinar on 'Exploring the Evolution of CPD'. The objective was to bring together global medical educators to consider perspectives of CPD from the role of global lifelong learners, the role of educators and the role of education providers and health regulators. The landscape of CPD is evolving, and the roles of each key player must include specific actions for facilitated change. Delivering competency outcomes-based learning, fit for purpose, to lifelong learners in health will require (1) learner agency, (2) leadership from educators and (3) providers of lifelong learning to come together to improve delivery of CPD that leads to meaningful change in practice care delivery.

Group Dynamics and Allocation of Advanced Heart Failure Therapies-Heart Transplants and Ventricular Assist Devices-By Gender, Racial, and Ethnic Group.

Background US regulatory framework for advanced heart failure therapies (AHFT), ventricular assist devices, and heart transplants, delegate eligibility decisions to multidisciplinary groups at the center level. The subjective nature of decision-making is at risk for racial, ethnic, and gender bias. We sought to determine how group dynamics impact allocation decision-making by patient gender, racial, and ethnic group. Methods and Results We performed a mixed-methods study among 4 AHFT centers. For ≈ 1 month, AHFT meetings were audio recorded. Meeting transcripts were evaluated for group function scores using de Groot Critically Reflective Diagnoses protocol (metrics: challenging groupthink, critical opinion sharing, openness to mistakes, asking/giving feedback, and experimentation; scoring: 1 to 4 [high to low quality]). The relationship between summed group function scores and AHFT allocation was assessed via hierarchical logistic regression with patients nested within meetings nested within centers, and interaction effects of group function score with gender and race, adjusting for patient age and comorbidities. Among 87 patients (24% women, 66% White race) evaluated for AHFT, 57% of women, 38% of men, 44% of White race, and 40% of patients of color were allocated to AHFT. The interaction between group function score and allocation by patient gender was statistically significant (P=0.035); as group function scores improved, the probability of AHFT allocation increased for women and decreased for men, a pattern that was similar irrespective of racial and ethnic groups. Conclusions Women evaluated for AHFT were more likely to receive AHFT when group decision-making processes were of higher quality. Further investigation is needed to promote routine high-quality group decision-making and reduce known disparities in AHFT allocation.

Learning patient-centredness with simulated/standardized patients: A realist review: BEME Guide No. 68.

BACKGROUND: Given the positive outcomes of patient-centred care on health outcomes, future doctors should learn how to deliver patient-centred care. The literature describes a wide variety of educational interventions with standardized patients (SPs) that focus on learning patient-centredness. However, it is unclear which mechanisms are responsible for learning patient-centredness when applying educational interventions with SPs. OBJECTIVE: This study aims to clarify how healthcare learners and professionals learn patient-centredness through interventions involving SPs in different healthcare educational contexts. METHODS: A realist approach was used to focus on what works, for whom, in what circumstances, in what respect and why. Databases were searched through 2019. Nineteen papers were included for analysis. Through inductive and deductive coding, CIC'MO configurations were identified to build partial program theories. These CIC'MOs describe how Interventions with SPs change the Context (C→C') such that Mechanisms (M) are triggered that are expected to foster patient-centredness as Outcome. RESULTS: Interventions with SPs create three contexts which are 'a safe learning environment,' 'reflective practice,' and 'enabling people to learn together.' These contexts trigger the following seven mechanisms: feeling confident, feeling a sense of comfort, feeling safe, self-reflection, awareness, comparing & contrasting perspectives, combining and broadening perspectives. A tentative final program theory with mechanisms belonging to three main learning components (cognitive, regulative metacognitive and affective) is proposed: Interventions with SPs create a safe learning environment (C') in which learners gain feelings of confidence, comfort and safety (affective M). This safe learning environment enables two other mutual related contexts in which learners learn together (C'), through comparing & contrasting, combining and broadening their perspectives (cognitive M) and in which reflective practice (C') facilitates self-reflection and awareness (metacognitive M) in order to learn patient-centeredness. CONCLUSION: These insights offer educators ways to deliberately use interventions with SPs that trigger the described mechanisms for learning patient-centredness.

Development and validation of a prediction rule for patients suspected of acute coronary syndrome in primary care: a cross-sectional study.

OBJECTIVE: To develop and validate a symptom-based prediction rule for early recognition of acute coronary syndrome (ACS) in patients with acute chest discomfort who call out-of-hours services for primary care (OHS-PC). DESIGN: Cross-sectional study. A diagnostic prediction rule was developed with multivariable regression analyses. All models were validated with internal-external cross validation within seven OHS-PC locations. Both age and sex were analysed as statistical interaction terms, applying for age non-linear effects. SETTING: Seven OHS-PC in the Netherlands. PARTICIPANTS: 2192 patients who called OHS-PC for acute chest discomfort (pain, pressure, tightness or discomfort) between 2014 and 2017. Backed up recordings of telephone triage conversations were analysed. PRIMARY AND SECONDARY OUTCOMES MEASURES: Diagnosis of ACS retrieved from the patient's medical records in general practice, including hospital specialists discharge letters. Performance of the prediction rules was calculated with the c-statistic and the final model was chosen based on net benefit analyses. RESULTS: Among the 2192 patients who called the OHS-PC with acute chest discomfort, 8.3% females and 15.3% males had an ACS. The final diagnostic model included seven predictors (sex, age, acute onset of chest pain lasting less than 12 hours, a pressing/heavy character of the pain, radiation of the pain, sweating and calling at night). It had an adjusted c-statistic of 0.77 (95% CI 0.74 to 0.79) with good calibration. CONCLUSION: The final prediction model for ACS has good discrimination and calibration and shows promise for replacing the existing telephone triage rules for patients with acute chest discomfort in general practice and OHS-PC. TRIAL REGISTRATION NUMBER: NTR7331.

The evolution and co-evolution of a primary care cancer research network: From academic social connection to research collaboration.

Academic networks are expected to enhance scientific collaboration and thereby increase research outputs. However, little is known about whether and how the initial steps of getting to know other researchers translates into effective collaborations. In this paper, we investigate the evolution and co-evolution of an academic social network and a collaborative research network (using co-authorship as a proxy measure of the latter), and simultaneously examine the effect of individual researcher characteristics (e.g. gender, seniority or workplace) on their evolving relationships. We used longitudinal data from an international network in primary care cancer research: the CanTest Collaborative (CanTest). Surveys were distributed amongst CanTest researchers to map who knows who (the 'academic social network'). Co-authorship relations were derived from Scopus (the 'collaborative network'). Stochastic actor-oriented models were employed to investigate the evolution and co-evolution of both networks. Visualizing the development of the CanTest network revealed that researchers within CanTest get to know each other quickly and also start collaborating over time (evolution of the academic social network and collaborative network respectively). Results point to a stable and solid academic social network that is particularly encouraging towards more junior researchers; yet differing for male and female researchers (the effect of individual researcher characteristics). Moreover, although the academic social network and the research collaborations do not grow at the same pace, the benefit of creating academic social relationships to stimulate effective research collaboration is clearly demonstrated (co-evolution of both networks).

Designing the learning of intraprofessional collaboration among medical residents.

BACKGROUND: To preserve quality and continuity of care, collaboration between primary-care and secondary-care physicians is becoming increasingly important. Therefore, learning intraprofessional collaboration (intraPC) requires explicit attention during postgraduate training. Hospital placements provide opportunities for intraPC learning, but these opportunities require interventions to support and enhance such learning. Design-Principles guide the design and development of educational activities when theory-driven Design-Principles are tailored into context-sensitive Design-Principles. The aim of this study was to develop and substantiate a set of theory-driven and context-sensitive Design-Principles for intraPC learning during hospital placements. METHODS: Based on our earlier research, we formulated nine theory-driven Design-Principles. To enrich, refine and consolidate these principles, three focus group sessions with stakeholders were conducted using a Modified Nominal Group Technique. Next, two work conferences were conducted to test the feasibility and applicability of the Design-Principles for developing intraPC educational activities and to sharpen the principles into a final set of Design-Principles. RESULTS: The theoretical Design-Principles were discussed and modified iteratively. Two new Design-Principles were added during focus group 1, and one more Design-Principle was added during focus group 2. The Design-Principles were categorised into three clusters: (i) Culture: building collaborative relations in a psychologically safe context where patterns or feelings of power dynamics between primary and secondary care physicians can be discussed; (ii) Connecting Contexts: making residents and supervisors mutually understand each other's work contexts and activities; and (iii) Making the Implicit Explicit: having supervising teams act as role models demonstrating intraPC and continuously pursuing improvement in intraPC to make intraPC explicit. Participants were unanimous in their view that the Design-Principles in the Culture cluster were prerequisites to facilitate intraPC learning. CONCLUSION: This study led to the development of 12 theory-driven and context-sensitive Design-Principles that may guide the design of educational activities to support intraPC learning during hospital placements.

Optimising telephone triage of patients calling for acute shortness of breath during out-of-hours primary care: protocol of a multiple methods study (Opticall).

INTRODUCTION: Callers with acute shortness of breath (SOB) are a challenge for telephone triage at out-of-hours primary care (OHS-PC) as SOB could be the sign of a potentially life-threatening disease, yet mostly is a symptom of a broad range of self-limiting disorders. Current telephone triage practice is mainly expert based and clear evidence on accuracy, safety and efficiency of the use of the Netherlands Triage Standard (NTS) by triage nurses based on the eventual clinical outcome is lacking for this domain. METHODS AND DATA ANALYSIS: Multiple methods study in five OHS-PC services in the Utrecht region, the Netherlands. Data will be collected from OHS-PC electronic health records (EHR) and backed up tapes of telephone triage conversations, which will be linked to routine primary care EHR data. In cross-sectional studies, we will (1) validate the NTS urgency classification for adults with SOB against final diagnoses and (2) develop diagnostic prediction models for urgent diagnoses (eg, composite endpoint of urgent diagnoses, pulmonary embolism, acute coronary syndrome, acute heart failure and pneumonia). We will develop improvement measures for the use of the NTS by triage nurses through practice observations and semistructured interviews with patients, triage nurses and general practitioners (GPs). In an action research approach, we will, in collaboration with these stakeholders, implement and evaluate our findings in both GP and triage nurse educational programmes as well as in OHS-PC services. ETHICS AND DISSEMINATION: The Medical Ethics Review Committee Utrecht, the Netherlands, approved the study protocol (protocol 21/361). We will take into account the 'code of conduct for responsible research' of the WHO, the EU General Data Protection Regulation and the 'Dutch Medical Treatment Contracts Act'. Results will be disseminated in peer-reviewed publications and at (inter)national meetings. TRIAL REGISTRATION NUMBER: NL9682.

Factors determining development of researchers within a research network on cancer diagnosis in primary care (CanTest): an interview study.

OBJECTIVES: Developing connections with other researchers in a network, learning informally through these connections and using them to reach goals, is expected to increase research capacity and strengthen performance. So far, this has not been empirically demonstrated. We assessed what and how network collaboration adds to development of researchers. DESIGN: Exploratory qualitative study using semistructured online interviews, analysed by inductive and deductive methods. For the deductive analysis, an existing value creation framework to study informal learning in networks was used and adjusted to our context. SETTING: The CanTest Collaborative-an international team of primary care cancer researchers working on early detection and diagnosis of cancer. PARTICIPANTS: Sixteen primary care cancer researchers. RESULTS: Connections with other researchers in an international network created diverse value cycles, where most outcomes were in the potential value cycle, acquiring knowledge, skills, social capital, resources and ideas. Not all potential value will be applied but many interviewees described realised as well as transformational value. In our context, the transformational value from the framework appeared to be related to other perspectives on the research process. Advancement of the network depends on opportunities, timing, role models and connections between different perspectives. CONCLUSIONS: Focus on the factors that are relevant for network advancement will support researchers in early detection and diagnosis of cancer research patients who participate in an international network and bring sustainable change in this domain. When, subsequently, researchers in the CanTest network bring about more realised and transformational learning outcomes, this will contribute to capacity development.

Missed Acute Coronary Syndrome During Telephone Triage at Out-of-Hours Primary Care: Lessons From A Case-Control Study.

OBJECTIVES: Serious adverse events at out-of-hours services in primary care (OHS-PC) are rare, and the most often concern is missed acute coronary syndrome (ACS). Previous studies on serious adverse events mainly concern root cause analyses, which highlighted errors in the telephone triage process but are hampered by hindsight bias. This study compared the recorded triage calls of patients with chest discomfort contacting the OHS-PC in whom an ACS was missed (cases), with triage calls involving matched controls with chest discomfort but without a missed ACS (controls), with the aim to assess the predictors of missed ACS. METHODS: A case-control study with data from 2013 to 2017 of 9 OHS-PC in the Netherlands. The cases were matched 1:8 with controls based on age and sex. Clinical, patient, and call characteristics were univariably assessed, and general practitioner experts evaluated the triage while blinded to the final diagnosis or the case-control status. RESULTS: Fifteen missed ACS calls and 120 matched control calls were included. Cases used less cardiovascular medication (38.5% versus 64.1%, P = 0.05) and more often experienced pain other than retrosternal chest pain (63.3% versus 24.7%, P = 0.02) compared with controls. Consultation of the supervising general practitioner (86.7% versus 49.2%, P = 0.02) occurred more often in cases than in controls. Experts rated the triage of cases more often as "poor" (33.3% versus 10.9%, P = 0.001) and "unsafe" (73.3% versus 22.5%, P < 0.001) compared with controls. CONCLUSIONS: To facilitate learning from serious adverse events in the future, these should also be bundled and carefully assessed without hindsight bias and within the context of "normal" clinical practice.

Dealing with Discontinuity in Cancer Care Trajectories: Patients' Solutions.

INTRODUCTION: Patients with cancer require specialized care from different care providers, challenging continuity of care in terms of information, relationships, and/or management. The recognition of discontinuity of care has led to different initiatives by the healthcare system over the years. Yet, making use of the theory on boundary objects and brokers, this research explores the active role of patients themselves in resolving discontinuity along their care trajectories. METHODS: Semi-structured interviews were conducted with 33 patients to unravel the discontinuities that they experience and their attempts to resolve these. Interview data were analyzed using directed-content analysis informed by concepts from boundary crossing literature (i.e., data were searched for potential boundary objects and brokers). RESULTS: To re-establish continuity of care, patients actively use the objects and people provided by the healthcare system when these meet their needs. Patients also introduce own objects and people into the care trajectory. As such, information and management discontinuity can typically be resolved. Relational continuity appears to be more difficult to resolve, in some cases leaving patients to take drastic measures, such as changing care providers. DISCUSSION: The use of boundary crossing theory in improving care from a patient perspective is relatively novel. When patients and providers together address the objects and people that support establishing continuity of care, a continuous care process may be encouraged. We advocate an integrated approach, rather than provider or healthcare system initiatives exclusively, to patient care and continuity.

Bidirectional learning opportunities: How GP-supervisors and trainees exchange knowledge.

INTRODUCTION: Workplace-based learning conversations can be a good opportunity for supervisors and trainees to learn from each other. When both professionals discuss their specific knowledge openly with each other, learning conversations may be a useful educational tool, for instance for learning how to apply evidence-based medicine (EBM) in the workplace. We do, however, need a better understanding of how the exchange of knowledge provides opportunities for such bidirectional learning. The aim of this study was therefore to analyse how trainees and supervisors currently handle bidirectional learning opportunities by describing in detail how supervisors respond to knowledge expressed by trainees during a learning conversation. METHOD: We video-recorded learning conversations between supervisors and trainees in general practice (GP). Within these learning conversations, EBM discussions on medical topics were selected and transcribed. We then identified, analysed using Conversation Analysis (CA) and categorised each expression of knowledge by the trainee and the supervisor's subsequent response. RESULTS: We found that when a trainee expresses knowledge during the learning conversation, supervisors either (a) refute the expressed knowledge, (b) immediately suggest an alternative or (c) pose (additional) questions. These responses have consequences for the learning opportunities of both trainee and supervisor: it is only when supervisors pose further questions that trainees are encouraged to elaborate on their knowledge, leading to a bidirectional learning opportunity. DISCUSSION: Improving EBM learning opportunities for both supervisors and trainees requires more than simply instructing trainees to express knowledge-based-for instance-on recent evidence more often. Inflexible institutional roles related to historical claims of supervisors' epistemic authority hamper bidirectional learning. Posing open questions during learning conversations enhances the flexibility of institutional roles while also creating bidirectional learning opportunities.

Gender-stratified analyses of symptoms associated with acute coronary syndrome in telephone triage: a cross-sectional study.

OBJECTIVES: To identify clinical variables that are associated with the diagnosis acute coronary syndrome (ACS) in women and men with chest discomfort who contact out-of-hours primary care (OHS-PC) by telephone, and to explore whether there are indications whether these variables differ among women and men. DESIGN: Cross-sectional study in which we compared patient and call characteristics of triage call recordings between women with and without ACS, and men with and without ACS. SETTING: Nine OHS-PC in the Netherlands. PARTICIPANTS: 993 women and 802 men who called OHS-PC for acute chest discomfort (pain, pressure, tightness or discomfort) between 2014 and 2016. PRIMARY OUTCOME MEASURE: Diagnosis of ACS retrieved from the patient's medical record in general practice, including hospital specialists' discharge letters. RESULTS: Among 1795 patients (mean age 58.8 (SD 19.5) years, 55.3% women), 15.0% of men and 8.6% of women had an ACS. In both sexes, retrosternal chest pain was associated with ACS (women with ACS vs without 62.3% vs 40.3%, p=0.002; men with ACS vs without 52.5% vs 39.7%, p=0.032; gender interaction, p=0.323), as was pressing/heavy/tightening pain (women 78.6% vs 61.5%, p=0.011; men 82.1% vs 57.4%, p=<0.001; gender interaction, p=0.368) and radiation to the arm (women 75.6% vs 45.9%, p<0.001; men 56.0% vs 34.8%, p<0.001; gender interaction, p=0.339). Results indicate that only in women were severe pain (65.4% vs 38.1%, p=0.006; gender interaction p=0.007) and radiation to jaw (50.0% vs 22.9%, p=0.007; gender interaction p=0.015) associated with ACS.Ambulances were dispatched equally in women (72.9%) and men with ACS (70.0%). CONCLUSION: Our results indicate there were more similarities than differences in symptoms associated with the diagnosis ACS for women and men. Important exceptions were pain severity and radiation of pain in women. Whether these differences have an impact on predicting ACS needs to be further investigated with multivariable analyses.

The effect of targeting Tie2 on hemorrhagic shock-induced renal perfusion disturbances in rats.

BACKGROUND: Hemorrhagic shock is associated with acute kidney injury and increased mortality. Targeting the endothelial angiopoietin/Tie2 system, which regulates endothelial permeability, previously reduced hemorrhagic shock-induced vascular leakage. We hypothesized that as a consequence of vascular leakage, renal perfusion and function is impaired and that activating Tie2 restores renal perfusion and function. METHODS: Rats underwent 1 h of hemorrhagic shock and were treated with either vasculotide or PBS as control, followed by fluid resuscitation for 4 h. Microcirculatory perfusion was measured in the renal cortex and cremaster muscle using contrast echography and intravital microscopy, respectively. Changes in the angiopoietin/Tie2 system and renal injury markers were measured in plasma and on protein and mRNA level in renal tissue. Renal edema formation was determined by wet/dry weight ratios and renal structure by histological analysis. RESULTS: Hemorrhagic shock significantly decreased renal perfusion (240 ± 138 to 51 ± 40, p < 0.0001) and cremaster perfusion (12 ± 2 to 5 ± 2 perfused vessels, p < 0.0001) compared to baseline values. Fluid resuscitation partially restored both perfusion parameters, but both remained below baseline values (renal perfusion 120 ± 58, p = 0.08, cremaster perfusion 7 ± 2 perfused vessels, p < 0.0001 compared to baseline). Hemorrhagic shock increased circulating angiopoietin-1 (p < 0.0001), angiopoietin-2 (p < 0.0001) and soluble Tie2 (p = 0.05), of which angiopoietin-2 elevation was associated with renal edema formation (r = 0.81, p < 0.0001). Hemorrhagic shock induced renal injury, as assessed by increased levels of plasma neutrophil gelatinase-associated lipocalin (NGAL: p < 0.05), kidney injury marker-1 (KIM-1; p < 0.01) and creatinine (p < 0.05). Vasculotide did not improve renal perfusion (p > 0.9 at all time points) or reduce renal injury (NGAL p = 0.26, KIM-1 p = 0.78, creatinine p > 0.9, renal edema p = 0.08), but temporarily improved cremaster perfusion at 3 h following start of fluid resuscitation compared to untreated rats (resuscitation + 3 h: 11 ± 3 vs 8 ± 3 perfused vessels, p < 0.05). CONCLUSION: Hemorrhagic shock-induced renal impairment cannot be restored by standard fluid resuscitation, nor by activation of Tie2. Future treatment strategies should focus on reducing angiopoietin-2 levels or on activating Tie2 via an alternative strategy.

Educational strategies to enhance EBM teaching and learning in the workplace: a focus group study.

OBJECTIVES: This study aimed to gather and synthesise educational strategies that can improve teaching and learning of evidence-based medicine (EBM) in the workplace, and make them concrete by listing ideas for implementing these strategies. Insight into current workplace-based EBM teaching and learning in general practice was the starting point to generate these strategies and ideas. DESIGN: Exploratory, qualitative focus group study, applying the consensus method of the nominal group technique. SETTING: Postgraduate medical education; general practitioner (GP) specialty training at University Medical Centre Utrecht, the Netherlands PARTICIPANTS: 33 GPs and 17 GP trainees, divided in four focus groups. Using opportunistic sampling, participants were selected from the GP workplace because of their role as supervisor or trainee. MAIN OUTCOMES: An overview of educational strategies and ideas on how to implement these strategies in the workplace, followed by the participants' global ranking of the most useful ideas. RESULTS: The supervisors and trainees generated a list of educational improvement strategies that can be applied in learning conversations, while observing each other's consultations, and in (multidisciplinary) learning opportunities in the workplace. Table 1 presents the educational strategies and suggestions for implementing them. Ideas regarded as most useful include taking turns to conduct consultations and observing the other, holding a structured, in-depth discussion after observation, preparing and discussing articles found in relevant journals and on-the-spot searching for relevant evidence during learning conversations. CONCLUSIONS: Participants provided an extensive list of educational strategies and ideas on how to implement EBM learning in daily practice. As a great deal of GP training takes place in clinical practice, supervisors and trainees could apply the suggested ideas to enhance EBM teaching and learning in the workplace.

Developing a regional transmural care database: A roadmap.

INTRODUCTION: In primary care health care systems, primary care physicians (PCPs) provide most basic care services, and if necessary, refer to secondary care for specialized work-up and treatment. If hospital care is required, agreement between PCPs and secondary care physicians (SCPs) on the conditions for patient referral and back-referral are considered crucial to providing high quality patient care. The regional healthcare network of Utrecht, a region in the Netherlands, developed a set of collaborative patient care agreements (CPCAs) for specific chronic conditions. Even though these CPCA are endorsed by all relevant regional health care organisations, the adoption of these agreements in practice remains substandard. In this project, through linkage of routine care data, as registered in daily practice by PCPs and SCPs, a regional transmural care database (RTD) was developed for monitoring the use of the CPCAs. Its data was transformed into' mirror data' used to support PCPs and SCPs in discussing and improving current practice and to support a learning healthcare system within the region. METHODS: The development of the RTD is part of a larger action research project on joint care, called ZOUT (an acronym which is translated as "The right care at the right place in the Utrecht region"). The RTD includes data from three regional hospitals, and about 70 affiliated primary care practices which are united in the Julius General Practitioners Network (JGPN). These data were extracted, linked and presented in the form of mirror data, following simple methods to allow replication of our approach. CPCAs addressing transmural care for three chronic conditions were selected. Data from the primary care practices and the hospitals were linked by an independent trusted third party. This enabled relevant hospital data to be added to the primary care dataset, thereby providing transmural routine care data for individual patients. RESULTS: During the development of the RTD, a roadmap was created including a detailed step-by-step checklist of the organizational, administrative, technical and legal arrangements which needed to be made. Legal and administrative challenges proved most challenging. Also, incompleteness of data and the impossibility to translate several agreements into extractable data limited the potential for providing a comprehensive overview of the extent to which agreements in the CPCA were adhered to in daily care. DISCUSSION: We present a systematic, comprehensive (technical as well as practical) and reproducible roadmap to developing a regional transmural care database suitable for generating mirror data on joint transmural care between PCPs and SCPs. This approach includes all technical steps in data selection and linkage, as well as the substantive steps that need to be taken in the analysis and application of the results. The mirror data, which reflects the follow-up of agreements formulated in the CPCAs, enabled shared reflection and discussion between PCPs and SCPs. This supports the search for bottlenecks and potentialities for improving daily collaborative care, thereby showing great potential to serve a learning regional healthcare system.
