Differences in Supervision on Peer Learning Wards: A Pilot Survey of the Supervisor's Perspective.

Introduction: Multiple students are placed on clinical wards simultaneously due to increasing student numbers. This has the potential to create stress for the supervisor and reduce quality of student learning. Peer learning as a pedagogical framework to supervise multiple students has been widely shown to have advantages for the students by developing teaching skills, team collaboration, and independence. However, whether peer learning impacts the characteristics of supervision and the experience of the supervisor is less understood. It is unknown whether wards that use peer learning as a pedagogical framework (peer learning wards) are any different compared to wards that do not (non-peer learning wards), from the supervisor's perspective. Methods: We aimed to develop and pilot test a questionnaire to compare peer-learning wards and non-peer learning wards from the supervisor's perspective. We used the AMEE 7-step guide to develop questions investigating supervision, the learning environment and satisfaction. We piloted the questionnaire with 46 nurse supervisors working on inpatient hospital wards in Stockholm, Sweden. We compared answers from peer learning with non-peer learning wards. We used Orthogonal Projections to Latent Structures (OPLS) discriminant analysis to show what differed between the wards. Results: Peer learning wards compared to non-peer learning wards had more student-centred activities, the physical space had more adaptations for students, more support available to the supervisor, and supervisors perceived greater overall satisfaction with the quality of education and with the ward as a whole. The variables that had most influence on the discrimination between the two ward types related to peer learning activities and perceptions (p=0.0034). Conclusion: This pilot study shows that peer learning wards differ compared to non-peer learning wards regarding peer learning activities and perceptions among supervisors. Our questionnaire needs to be distributed on a larger scale to validate our findings and explore further the way in which the pedagogical framework and peer learning can affect supervision and satisfaction.

Self-report and device-based physical activity measures and adherence to physical activity recommendations: a cross-sectional survey among people with inflammatory joint disease in four European countries.

OBJECTIVES: Self-monitoring of physical activity (PA) has the potential to contribute to successful behaviour change in PA interventions in different populations, including people with inflammatory joint diseases (IJDs). The objectives of this study were to describe the use and knowledge of self-report-based and device-based PA measures in people with IJDs in four European countries, and to explore if the use of such devices, sociodemographic or disease-related variables were associated with adherence to the recommendations of at least 150 min of moderate to vigorous PA per week. SETTING: Cross-sectional survey, performed in 2015-2016. PARTICIPANTS: People with IJDs in Belgium, Denmark, Ireland and Sweden. PRIMARY AND SECONDARY OUTCOME MEASURES: Use of self-report and device-based PA measures, receipt of instructions how to use PA measures, confidence in using them, adherence to PA recommendations and associated factors for adherence to PA recommendations. RESULTS: Of the 1305 respondents answering questions on PA measures, 600 (46%) reported use of any kind of self-report or device-based measures to self-monitor PA. Between country differences of 34%-58% was observed. Six per cent and four per cent received instructions from health professionals on how to use simple and complex devices, respectively. Independent associated factors of fulfilment of recommendations of PA were living in Ireland (OR=84.89, p<0.001) and Sweden (OR=1.68, p=0.017) compared with living in Denmark, not perceiving activity limitations in moderate activities (OR=1.92, p<0.001) and using a device to measure PA (OR=1.56, p<0.001). Those living in Belgium (OR=0.21, p<0.001) were less likely to fulfil recommendations of PA. CONCLUSIONS: Almost half of the participants with IJDs used self-report-based or deviced-based PA measures, although few used wearable devices regularly. The results indicate that participants meeting public PA health guidelines were engaged in self-monitoring of PA.

Organizational and patient-level predictors for attaining key risk factor targets in cardiac rehabilitation after myocardial infarction: The Perfect-CR study.

BACKGROUND: Benefits of cardiac rehabilitation (CR) programme components on attaining risk factor targets post-myocardial infarction (MI) and their predictive strength relative to patient characteristics remain unclear. We aimed to identify organizational and patient-level predictors of risk factor target attainment at one-year post-MI. METHODS: In this observational study data on CR organization at 78 Swedish CR centres was collected and merged with patient-level registry data (n = 7549). Orthogonal partial least squares discriminant analysis identified predictors (Variables of Importance for the Projection (VIP) values >0.8) of attaining low-density lipoprotein-cholesterol (LDL-C) <1.8 mmol/L, blood pressure (BP) <140/90 mmHg and smoking abstinence. RESULTS: The strongest predictors (VIP [95% CI]) for attaining LDL-C and BP targets were offering psychosocial management (2.14 [1.78-2.50]; 2.45 [1.91-2.99]), having a psychologist in the CR team (1.62 [1.36-1.87]; 2.05 [1.67-2.44]), extended opening hours (2.13 [2.00-2.27]; 1.50 [0.91-2.10]), adequate facilities (1.54 [0.91-2.18]; 1.89 [1.38-2.40]), and having a medical director (1.70 [0.91-2.48]; 1.46 [1.04-1.88]). The strongest patient-level predictors of attaining LDL-C and/or BP targets were low baseline LDL-C (3.95 [3.39-4.51]) and having no history of hypertension (2.93 [2.60-3.26]), respectively, followed by exercise-based CR participation (1.38 [0.66-2.10]; 1.46 [1.14-1.78]). For smoking abstinence, the strongest organizational predictor was varenicline being prescribed by CR physicians (1.88 [0.95-2.80]) and patient-level predictors were participation in exercise-based CR (2.47 [2.07-2.88]) and group education (1.92 [1.43-2-42]), and no cardiovascular disease history (2.13 [1.78-2.48]). CONCLUSIONS: We identified multiple CR organizational and patient-level predictors of attaining risk factor targets post-MI. These results may influence the future design of comprehensive CR programmes.

Changes in the plasma microvesicle proteome during the ovarian hyperstimulation phase of assisted reproductive technology.

The incidence of pulmonary and venous thromboembolism is increased during the first trimester of pregnancies after assisted reproductive technology (ART) compared to spontaneous conception. We previously found that haemostatic plasma variables changed but within normal limits during controlled ovarian hyperstimulation (COH) concomitant with a major increase in plasma microvesicles (MVs) and markers indicating cell activation. We now explored the proteome of these MVs. Thirty-one women undergoing ART were blood sampled at down-regulation (DR) of oestrogen and at high level stimulation (HLS) with its 10-100-fold increased oestrogen level. Samples were analysed by liquid chromatography and tandem mass spectrometry to identify and quantify the proteome. We identified 306 proteins in the MVs and 72 had changed significantly at HLS compared to DR and more than 20% of them were associated with haemostasis. Thus, proteins related to both haemostasis and complement activation altered in plasma MVs in parallel with MV activation during COH. This needs to be further explored in the clinical context.

Incidence of pulmonary and venous thromboembolism in pregnancies after in vitro fertilization with fresh respectively frozen-thawed embryo transfer: Nationwide cohort study.

BACKGROUND: The assisted reproductive technique in vitro fertilization (IVF) is associated with an increased risk of venous thromboembolism (VTE) and pulmonary embolism (PE) during the first trimester. OBJECTIVES: To compare the incidence of VTE and PE during the first trimester of IVF pregnancies using fresh or frozen-thawed embryo transfer to that during natural pregnancies. PATIENT/METHODS: Nationwide Swedish registry-based cohort study of women who gave birth (n = 902 891) at the age of 15-50 years to their first child from the 1st of January 1992 until the 31st of December 2012. Exposure groups were IVF with fresh respectively frozen-thawed embryo transfer. Incidences of VTE and PE were calculated, and time-varying hazard ratios estimated for all trimesters after fresh respectively frozen-thawed embryo transfer IVF and compared to natural conception. RESULTS AND CONCLUSION: Women giving birth after fresh embryo transfer IVF had a more than eightfold increased incidence of venous thromboembolism (hazard ratio [HR] 8.96, 95% CI 6.33 to 12.67) and pulmonary embolism during the first trimester, (HR 8.69, 95% CI 3.83 to 19.71) compared to women giving birth after natural conception. The incidence of VTE in women giving birth after frozen-thawed embryo transfer was not increased during the first trimester. To conclude, fresh embryo transfer IVF was associated with a significantly increased incidence of VTE and PE during the first trimester. These results suggest that frozen-thawed embryo transfer could be a preferred method of IVF with a minimised maternal risk.

Nursing Students Learn to Handle Stress and to Prioritize in a Complex Context During Workplace Learning in Acute Internal Medicine Care - An Ethnographic Study.

INTRODUCTION: A common focus in many studies, in the short-term perspective, is to evaluate students' workplace learning and its outcome. However, the outcome can be perceived differently depending on when it was evaluated. The aim of this study was to explore student nurses' learning activities in an acute internal medicine unit and the nurses perceived learning outcome in a long-term perspective. MATERIAL AND METHODS: Repetitive ethnographic observations were performed in an internal medicine care unit at a teaching hospital in Sweden between 2011 and 2013. Four student nurses and supervisors were repetitively observed. Two years later retrospective interviews were performed with four nurses who had performed workplace learning, as students, in this unit during the observation period. An inductive comparative analysis involving all interviews and observational data was applied. RESULTS: Three themes were identified: To handle shifting situations - illustrating how student nurses learnt to adapt to shifting situations, to manage stress, to create structure and space for learning and to deal with hierarchies; To build relationships - illustrating how student nurses learnt to collaborate and to interact with patients; To act independently - illustrating how student nurses trained to act independently in the unit, took responsibility, and prioritized in this complex context. CONCLUSION: Learning activities in a complex acute medical unit setting were characterized by a high workload and frequent stressful situations, and a demand on students to interact, to take responsibility, and to prioritize. To learn in such a stressful context, have in a long-term perspective, a potential to develop students' embodied understanding of and in practice, making them more prepared to work and independently apply their nursing expertise in similar contexts as graduated nurses.

Prognostic Value of Circulating Microvesicle Subpopulations in Ischemic Stroke and TIA.

Platelet microvesicles (PMV) have previously been found elevated in acute ischemic stroke (IS) and could be biomarkers for risk of recurrence. PMV surface antigens such as P-selectin and phosphatidylserine (PS) reflect platelet activation and procoagulance. Tissue factor-positive microvesicles (TF+MV) are considered procoagulant, in particular if co-expressing PS. We enumerated MV subpopulations with these surface antigens in a cohort of 211 patients with primarily non-cardioembolic IS or transient ischemic attack (TIA) and investigated their association with long-term outcome. MV concentrations were determined by flow cytometry in the acute and convalescent phase. Primary outcome was a composite of fatal and non-fatal recurrent IS or myocardial infarction. Secondary outcomes were recurrent IS and all-cause mortality. Outcome events were obtained from Swedish registers during a follow-up of 1100 patient years. Concentrations of PS-positive and PS-negative MV populations were elevated in patients compared with healthy controls in both the acute and convalescent phase. PS+TF+PMV displayed pronounced elevations, median fold change 77 in the acute phase (p < 0.0001) but were not associated with outcome, neither were PS+P-selectin+PMV. The only subpopulation positively associated with primary outcome was PS-TF+PMV, with adjusted hazard ratio of 1.86 (1.04-3.31, p = 0.036) by Cox regression. Unexpectedly, several MV subpopulations tended to be associated with reduced risk of poor long-term outcome. Our results suggest that PS+TF+PMV may be a promising marker for cerebral ischemia, and that the in vivo generation of PS-MV after IS/TIA warrants further study. Future MV studies should ideally enumerate PS+ and PS-MV subpopulations separately.

Cardiac rehabilitation after acute myocardial infarction in Sweden - evaluation of programme characteristics and adherence to European guidelines: The Perfect Cardiac Rehabilitation (Perfect-CR) study.

BACKGROUND: While patient performance after participating in cardiac rehabilitation programmes after acute myocardial infarction is regularly reported through registry and survey data, information on cardiac rehabilitation programme characteristics is less well described. AIM: The aim of this study was to evaluate Swedish cardiac rehabilitation programme characteristics and adherence to European Guidelines on Cardiovascular Disease Prevention. METHOD: Cardiac rehabilitation programme characteristics at all 78 cardiac rehabilitation centres in Sweden in 2016 were surveyed using a web-based questionnaire (100% response rate). The questions were based on core components of cardiac rehabilitation as recommended by European Guidelines. RESULTS: There was a wide variation in programme duration (2-14 months). All programmes reported offering an individual post-discharge visit with a nurse, and 90% (n = 70) did so within three weeks from discharge. Most programmes offered centre-based exercise training (n = 76, 97%) and group educational sessions (n = 61, 78%). All programmes reported to the national audit, SWEDEHEART, and 60% (n = 47) reported that performance was regularly assessed using audit data, to improve quality of care. Ninety-six per cent (n = 75) had a core team consisting of a cardiologist, a physiotherapist and a nurse and 76% (n = 59) reported having a medical director. Having other allied healthcare professionals included in the cardiac rehabilitation team varied. Forty per cent (n = 31) reported having regular team meetings where nurses, physiotherapists and cardiologist could discuss patient cases. CONCLUSION: The overall quality of cardiac rehabilitation programmes provided in Sweden is high. Still, there are several areas of potential improvement. Monitoring programme characteristics as well as patient outcomes might improve programme quality and patient outcomes both at a local and a national level.

Possibilities for interprofessional learning at a Swedish acute healthcare ward not dedicated to interprofessional education: an ethnographic study.

OBJECTIVES: Almost all healthcare today is team-based in collaboration over professional borders, and numerous students have work-based learning in such contexts. However, interprofessional learning (IPL) in clinical settings has mostly been systematically explored in specially designed contexts dedicated to interprofessional education (IPE). This study aimed to explore the possibilities for IPL activities, and if or how they occur, in an acute ward context not dedicated to IPE. DESIGN AND SETTING: Between 2011 and 2013 ethnographic observations were performed of medical and nursing students' interactions and IPL during early clerkship at an acute internal medicine ward in Sweden. Field notes were taken and analysed based on the framework of IPE: learning with, from and about. PARTICIPANTS: 21 medical, 4 nursing students and 30 supervisors participated. RESULTS: Learning with-there were no organised IPE activities. Instead, medical and nursing students learnt in parallel. However, students interacted with staff members from other professions. Learning from-interprofessional supervision was frequent. Interprofessional supervision of nursing students by doctors focused on theoretical questions and answers, while interprofessional supervision of medical students by nurses focused on the performance of technical skills. Learning about-students were observed to actively observe interactions between staff and learnt how staff conducted different tasks. CONCLUSION: This study shows that there were plenty of possibilities for IPL activities, but the potential was not fully utilised or facilitated. Serendipitous IPL activities differed between observed medical and nursing students. Although interprofessional supervision was fairly frequent, students were not learning with, from or about each other over professional borders.

Microvascular capillary assessment in relation to forearm blood flow.

OBJECTIVE: To study whether vascular reactivity as assessed by the methods forearm blood flow (FBF) and postocclusive reactive hyperaemia (PRH) in the nail fold was related as a measure of endothelium-dependent vasodilation in the microcirculation. METHODS: Microvascular reactivity was assessed in forearm blood flow and in the nail fold by vital capillaroscopy of individual microvessels as postocclusive reactive hyperaemia. Vascular reactivity was assessed at baseline (n = 25) as well as after infusion of acetylcholine and of sodium nitroprusside (n = 13). We also performed a multivariate regression analysis to assess whether forearm blood flow or flow-mediated dilatation related to postocclusive reactive hyperaemia. RESULTS: This study showed a distinct microvascular response to both acetylcholine (endothelium-dependent vasodilation) and sodium nitroprusside (endothelium-independent vasodilation) during forearm blood flow assessment and postocclusive reactive hyperaemia assessment in the nail fold (n = 13). These changes were inversely related (r- = -0·57; P<0·05). CONCLUSIONS: Forearm blood flow was inversely correlated to postocclusive reactive hyperaemia. Postocclusive reactive hyperaemia was shortened after infusion with both acetylcholine and sodium nitroprusside. This occurred in parallel with the expected increase in forearm blood flow, conceivably reflecting that both methods can be used to assess endothelium-dependent vasodilation in the microcirculation.

Inability to act was associated with an extended delay prior to care-seeking, in patients with an acute myocardial infarction.

BACKGROUND: The out-of-hospital mortality in patients with acute myocardial infarction remains unchanged in contrast to a decrease in inhospital mortality. Interventions aiming to shorten patient delay have been largely unsuccessful. A deeper understanding is apparently needed on patients' appraisal prior to care-seeking. AIM: To investigate whether appraisal processes influence patient delay, and if the questionnaire 'Patients' appraisal, emotions and action tendencies preceding care seeking in acute myocardial infarction' (PA-AMI) could discriminate between patients with prolonged care-seeking and those with a short delay. METHODS: A cross-sectional study including 326 acute myocardial infarction patients filling out the validated questionnaire PA-AMI. The impact of subscales on delay was analysed by projection to latent structures regression. Discrimination opportunities between patients with short and long delays were analysed by projection to latent structures discriminant analysis. RESULTS: The subscales 'perceived inability to act' and 'symptom appraisal' had a major impact on patient delay (P<0.0001). 'Perceived inability to act' had its main influence in patients with a delay exceeding 12 hours, and 'symptom appraisal' had its main influence in patients with a delay shorter than one hour. CONCLUSION: Appraisal processes influence patient delay. Acute myocardial infarction patients with a prolonged delay were, besides a low perceived symptom severity and urgency to seek medical care, characterised by a perceived loss of control and ability to act. Therefore, future interventions aimed at decreasing delay should pay attention to appraisal processes, and perceived inability to act may be a sign of a health threat and therefore a signal to seek medical care.

Influence of contextual factors on quality of primary care in children with asthma.

OBJECTIVE: Asthma is a common chronic disease among children, quality assurance is thus important. Adherence to pre-specified quality indicators of practice guidelines could be used to assess the quality of asthma care. The aim was to estimate which contextual factors that had an influence on the primary health care centres (PHCs) adherence to the quality indicators as stated in the practice guidelines. METHOD: A pragmatic cross-sectional study was performed comprising 14 PHCs in Sweden. Included contextual factors were socio-demographic characteristics, organizational characteristics, and indicators regarding engagement in asthma care. Documentation on adherence to the quality indicators was retrieved from the medical health care records. Quality indicators included documentation of history of allergy and risk factors, diagnostics and patient support performed, and pharmacological treatment. To score adherence, a composite quality indicator (CQI) was computed for each PHC. A multivariable regression analysis was performed by orthogonal projection to latent structures (OPLS). By this analysis, the relationship between the result variable (CQI) and 26 pre-specified contextual factors was assessed. RESULTS: There was a wide variation of CQI between the PHCs. The OPLS analysis identified that 10 of the contextual factors influenced CQI. The most pronounced influences were found in more time scheduled for asthma care, a lower age-limit for performing spirometry, a lower duty-grade for general practitioners, and a higher activity at asthma educational seminars. We found no influence of socio-demographic contextual factors. CONCLUSION: We found that some of the contextual factors at the PHCs influenced the quality of performed care. Evidence-based care in paediatric asthma may thus be presumed to be facilitated by allocating time, by improving interprofessional collaboration, and by creating structures and opportunities for commitment to asthma care.

Readmission and mortality in patients treated by interprofessional student teams at a training ward compared with patients receiving usual care: a retrospective cohort study.

OBJECTIVE: This study aimed to compare the rate of patient readmissions and mortality between care provided at an orthopaedic interprofessional training ward (IPTW) and usual care. DESIGN: Retrospective cohort study. SETTING: Orthopaedic wards at a level II trauma centre at a Swedish university teaching hospital between 2006 and 2011. PARTICIPANTS: Two cohorts were identified: (1) a control cohort that had not received care at the IPTW, and (2) patients who had been treated for at least 1 day at the IPTW. MAIN OUTCOME MEASURES: Readmission at 90 days and 1-year mortality. RESULTS: We included 4652 controls and 1109 in the IPTW group. The mean age was 63 years, and 58% were women. The groups did not differ in any of the outcomes: the readmission rate in the control and IPTW groups was 13.5% and 14.0%, respectively, while mortality was 5.2% and 5.3%, respectively. This lack of difference remained after adjusting for confounders. CONCLUSION: Interprofessional undergraduate training in patient-based settings can be performed in a level II trauma hospital with satisfactory patient safety.

Citrullinated histone H3 as a novel prognostic blood marker in patients with advanced cancer.

Citrullinated histone H3 (H3Cit) is a central player in the neutrophil release of nuclear chromatin, known as neutrophil extracellular traps (NETs). NETs have been shown to elicit harmful effects on the host, and were recently proposed to promote tumor progression and spread. Here we report significant elevations of plasma H3Cit in patients with advanced cancer compared with age-matched healthy individuals. These elevations were specific to cancer patients as no increase was observed in severely ill and hospitalized patients with a higher non-malignant comorbidity. The analysis of neutrophils from cancer patients showed a higher proportion of neutrophils positive for intracellular H3Cit compared to severely ill patients. Moreover, the presence of plasma H3Cit in cancer patients strongly correlated with neutrophil activation markers neutrophil elastase (NE) and myeloperoxidase (MPO), and the inflammatory cytokines interleukin-6 and -8, known to induce NETosis. In addition, we show that high levels of circulating H3Cit strongly predicted poor clinical outcome in our cohort of cancer patients with a 2-fold increased risk for short-term mortality. Our results also corroborate the association of NE, interleukin-6 and -8 with poor clinical outcome. Taken together, our results are the first to unveil H3Cit as a potential diagnostic and prognostic blood marker associated with an exacerbated inflammatory response in patients with advanced cancer.

Enhanced hospital-based learning at a medical school through application of management principles - a case study.

BACKGROUND: A hospital with all its brimming activity constitutes a unique learning environment for medical students. However, to organise high-quality education within this context is a task of great complexity. This paper describes a teaching hospital case, where management principles were applied to enhance the learning quality of medical education. METHODS: Traditional attempts from the faculty had been unsuccessful in improving learning among medical students at a teaching hospital. We therefore applied management principles to be able to improve the learning quality. An evaluation was performed from the perspectives of management (course directors/ heads of health care departments), medical students, and physician supervisors. Presages were defined, including educational resources and management; processes were adjusted, including learning activities and staff schedules; and products were assessed. RESULTS: Charting and benchmarking the use of local educational resources identified unused funding. Structured recurrent collaboration within resource utilization was established between course directors and heads of all concerned health care departments. By formulating a joint agreement, the identified assets were used to reorganise the course, to create constructive alignment, and to increase assigned supervisor time. This resulted in a sustainable improvement of learning quality and culture. CONCLUSION: By using management principles in combination with a scholarship of teaching and learning, it was possible to locate and redistribute educational resources in an effective way. This improved student learning and the learning culture of the health care departments. We propose that such an initiative could also be transferable to other contexts. Faculty leaders facing similar problems should consider the advantages of a structured collaboration with health care department heads.

N-terminal pro B-type natriuretic peptide in systematic screening for atrial fibrillation.

OBJECTIVE: Screening for atrial fibrillation (AF) in individuals aged 65 and above is recommended by the European Society of Cardiology. Increased levels of the biomarker N-terminal pro B-type natriuretic peptide (NT-proBNP) has in cohort studies been associated with incident AF.The aim of this study was to assess whether NT-proBNP could be useful for AF detection in systematic screening. METHODS: The Strokestop study entailed 7173 Swedish residents aged 75/76 that were screened for AF using twice daily intermittent ECG recordings during 2 weeks. In a substudy of 886 participants, the last 815 consecutive participants and 71 individuals with newly detected AF, levels of NT-proBNP were determined. RESULTS: Participants with newly detected AF (n=96) had a median NT-proBNP of 330 ng/L (IQR 121;634). In individuals without AF (n=742), median NT-proBNP was 171 ng/L (IQR 95;283), p<0.001. The CHA2DS2-VASc parameters did not differ significantly between individuals with newly detected AF and without AF nor between newly detected AF in the NT-proBNP cohort compared with the cohort where NT-proBNP was not assessed. Using an NT-proBNP cut-off of ≥125 ng/L in a non-acute setting yielded a negative predictive value of 92%, meaning that 35% fewer participants would need to be screened when applied to systematic AF screening. Adding weight to NT-proBNP further reduced participants needed to be screened with a preserved sensitivity. CONCLUSIONS: NT-proBNP was increased in individuals with newly detected AF. Prospective studies could clarify if NT-proBNP can be used to correctly select individuals that benefit most from AF screening. CLINICAL TRIALS: ClinicalTrials.gov. Identifier: NCT01593553.

Microparticles reveal cell activation during IVF - a possible early marker of a prothrombotic state during the first trimester.

Cell-derived microparticles (MPs) are known to be elevated in a number of diseases related to arterial and venous thromboembolism (VTE), such as acute myocardial infarction, VTE (deep-vein thrombosis and pulmonary embolism) and peripheral arterial disease. IVF-associated pregnancies have previously been shown to be associated with an increased incidence of VTE, mechanisms behind being unknown and sparsely studied. Our objective was to assess cell activation during IVF through analysis of MP levels and phenotype following ovarian stimulation. Thirty-one women undergoing IVF were included and blood samples were collected at down regulation of oestrogen and at high level stimulation with 10- to 100-fold increased endogenous oestrogen levels. MPs were analysed by flow cytometry and phenotyped according to size and protein expression. We found that overall phosphatidylserine positive platelet-, endothelial- and monocyte-derived MPs significantly increased following ovarian stimulation with increased levels of platelet activation markers CD40 ligand and P-selectin. Furthermore, there was an increase in endothelial-derived MPs exposing activation marker E-selectin and monocyte-derived MPs, while neutrophil-derived MPs decreased slightly. In conclusion we found a major increase in MPs and markers indicating cell activation in parallel with the profound oestrogen boost during IVF. To assess whether these changes in MPs are associated with thromboembolic events requires extended longitudinal studies.

Cost-effectiveness of case-based training for primary care physicians in evidence-based medicine of patients with coronary heart disease.

BACKGROUND: We have shown that a case-based training programme for general practitioners, aimed to implement evidence-based care of patients at very high risk of coronary death, was associated with decreased mortality. In the present study we assessed long-term cost-effectiveness of this programme. DESIGN: Registry-based long-term cost-effectiveness analysis on a clinical trial. METHODS: Costs of the programme, health care, drugs and added years of life were included. Costs were adjusted to 2012 level and discounted by 3%. Life-years gained were estimated as the difference between the survival curves of the trial. The effectiveness measure, quality adjusted life-years (QALYs), was constructed by multiplying each life-year with a quality of life weight corresponding to the health status of that year. QALYs were also discounted by 3%. Incremental cost-effectiveness ratio (ICER) was estimated as the incremental cost per QALY gained. RESULTS: The number of undiscounted life-years gained was 365 days in the intervention group as compared to control (p = 0.02). The number of discounted QALYs gained was 0.66. The net increase in total costs was estimated as 17,862 € when costs of added years of life were included and 4621 € exclusive of these costs. This implied an ICER of 27,063 € per gained QALY. This ICER is well below commonly used threshold values of the societal willingness to pay for a QALY. CONCLUSIONS: The results show that a case-based training programme of general practitioners is a cost-effective way to save years of life in patients with very high risk of coronary death.
