  • Interprofessional education in a student-led emergency department : A realist evaluation
  • 2017
  • Ingår i: Journal of Interprofessional Care. - Taylor & Francis. - 1356-1820. ; 31:2, s. 199-206
  • Tidskriftsartikel (refereegranskat)abstract
    • This article reports a realist evaluation undertaken to identify factors that facilitated or hindered the successful implementation of interprofessional clinical training for undergraduate students in an emergency department. A realist evaluation provides a framework for understanding how the context and underlying mechanisms affect the outcome patterns of an intervention. The researchers gathered both qualitative and quantitative data from internal documents, semi-structured interviews, observations, and questionnaires to study what worked, for whom, and under what circumstances in this specific interprofessional setting. The study participants were medical, nursing, and physiotherapy students, their supervisors, and two members of the emergency department's management staff. The data analysis indicated that the emergency ward provided an excellent environment for interprofessional education (IPE), as attested by the students, supervisors, and the clinical managers. An essential prerequisite is that the students have obtained adequate skills to work independently. Exemplary conditions for IPE to work well in an emergency department demand the continuity of effective and encouraging supervision throughout the training period and supervisors who are knowledgeable about developing a team.

  • A Theory-Based Study of Factors Explaining General Practitioners' Intention to Use and Participation in Electronic Continuing Medical Education
  • 2016
  • Ingår i: Journal of Continuing Education in the Health Professions. - Lippincott Williams & Wilkins. - 0894-1912. ; 36:4, s. 290-294
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Electronic modes of continuing medical education (eCME) can provide an appropriate and scalable way of updating the knowledge and skills of general practitioners (GPs). To optimize the adoption of eCME and develop efficient and cost-effective eCME programs, factors explaining GPs' intention to use eCME must first be elucidated. Methods: Using the Theory of Planned Behavior as a framework, we developed a questionnaire and administered it to GPs in seven CME seminars in Isfahan, Iran, in 2014. Three domains of GPs' intention to use eCME were measured: attitudes, perceived behavioral control, and subjective norms. We used linear and logistic regression to identify the main predictors of intention and behavior. Results: GPs who had high score in perceived behavioral control and a more positive attitude toward e-learning had a higher intention to adopt it for CME. In contrast, subjective norms (eg, social pressures to use eCME) were not a predictor. Attitude toward usefulness of eCME was the main predictor of being an actual eCME user. Discussion: Perceived behavioral control and attitude constitute the main predictors of the intention to use eCME. Establishing discussions forums and strengthening organizational support for eCME through an increased awareness among clinical superiors and CME managers would be expected to increase GPs' intention to use eCME.

  • Applicability of the theory of planned behavior in explaining the general practitioners eLearning use in continuing medical education
  • 2016
  • Ingår i: BMC Medical Education. - BioMed Central. - 1472-6920. ; 16
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: General practitioners (GP) update their knowledge and skills by participating in continuing medical education (CME) programs either in a traditional or an e-Learning format. GPs' beliefs about electronic format of CME have been studied but without an explicit theoretical framework which makes the findings difficult to interpret. In other health disciplines, researchers used theory of planned behavior (TPB) to predict user's behavior. Methods: In this study, an instrument was developed to investigate GPs' intention to use e-Learning in CME based on TPB. The goodness of fit of TPB was measured using confirmatory factor analysis and the relationship between latent variables was assessed using structural equation modeling. Results: A total of 148 GPs participated in the study. Most of the items in the questionnaire related well to the TPB theoretical constructs, and the model had good fitness. The perceived behavioral control and attitudinal constructs were included, and the subjective norms construct was excluded from the structural model. The developed questionnaire could explain 66 % of the GPs' intention variance. Conclusions: The TPB could be used as a model to construct instruments that investigate GPs' intention to participate in e-Learning programs in CME. The findings from the study will encourage CME managers and researchers to explore the developed instrument as a mean to explain and improve the GPs' intentions to use eLearning in CME.

  • Cardiovascular assessment in middle-aged male long distance runners
  • 2012
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • Endurance events such as long distance running races are increasing in popularity and convey multiple health benefits. However, such exercise forms also represent a major challenge to human cardiovascular physiology and are associated with a momentarily increased risk for adverse cardiac events. Using the world’s largest cross-country running race Lidingöloppet as a model of endurance events, this thesis aims to: 1) investigate male and female participation and performance trends 2) detail the cardiovascular findings of a comprehensive cardiovascular preparticipation evaluation in novice male race participants aged 45 years and older 3) study the impact of race participation on cardiac autonomic tone and 4) assess features of cardiovascular function and vectorcardiography (VCG), and their response to endurance exercise in individuals with early repolarisation (ER). Study I Participation and performance trends were investigated in >120,000 runners partaking in the Lidingöloppet between 1993 and 2007. In a subgroup of 249 middle-aged males, the association between the cardiac biomarker NT-proBNP and runtime was also studied. Participation increased over the study period, particularly in females and older males, while participants’ fitness deteriorated, as measured by an average increase in runtime of 21 ± 31 min. Longer runtimes were independently associated with higher levels of NT-proBNP. Study II A preparticipation cardiovascular exam was performed in 153 middle-aged male first-time Lidingöloppet race participants. Runners were assessed by medical history and physical exam, 12-lead ECG, echocardiography, and blood tests. 9 % of runners required further diagnostic work-up and 2 % were discouraged from race participation due to cardiac abnormalities that could increase their risk of exercise- related cardiac events. Study III Heart rate (HR) and heart rate variability (HRV) was continuously measured from 48 hours before until 96 hours after a Lidingöloppet 30km race. Compared to pre-race values, HR was elevated during the night after the race while HRV remained depressed for 64 [51 - 96] hours after the race. A reduced HR recovery and a greater fall in HRV post race were associated with higher levels of high-sensitivity troponin T (hsTnT). Study IV The prevalence and associated cardiac features of ER, characterized by ST-segment elevation (STE) and/or J-waves, was investigated in 153 middle-aged males registered for first-time participation in the Lidingöloppet 10, 15 or 30km race. ER was present in 40 % and generally associated with features of better cardiovascular fitness. The cardiovascular effects of participating in the 30km race (n= 94) were also assessed after the race; runners with J-waves, but not with STE alone, showed changes of repolarisation parameters usually considered unfavourable (e.g. prolonged T peak-to-end (Tpe) and QTc). Conclusion This thesis demonstrated that increased participation in a long distance running event (Lidingöloppet) was paralleled by deteriorating runtimes. In middle-aged men, longer runtimes were associated with higher levels of NT-proBNP. These findings may raise concern regarding the fitness and cardiovascular health of some of today’s race participants. A comprehensive preparticipation evaluation identified 9 % of first- time runners needing additional work-up and 2% who were ultimately discouraged from participating, suggesting that such a protocol is useful to identify individuals requiring further testing prior to vigorous exercise. After the race there was a prolonged depression of HRV. The magnitude and duration of HRV depression correlated with higher levels of hsTnT, suggesting that the degree of troponin (Tn) increase after strenuous exercise may reflect the level of exercise-induced cardiovascular stress. ER was generally associated with a benign cardiovascular profile, although subjects with J-waves showed post-race changes in some parameters of ventricular repolarisation that are usually associated with increased arrhythmia propensity. More research into the mechanisms and potential preventive measures of adverse exercise related effects on cardiac function is warranted.

  • Early Repolarization in Middle-Age Runners-Cardiovascular Characteristics.
  • 2014
  • Ingår i: Medicine & Science in Sports & Exercise. - 0195-9131. ; 46:7, s. 1285-1292
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: This study aimed to assess the prevalence and patterns of early repolarization (ER) in middle-age long-distance runners, its relation to cardiac structure and function, and its response to strenuous physical activity. Methods: Male first-time cross-country race participants >45 yr were assessed pre-and postrace by medical history and physical examination, 12-lead ECG, vectorcardiography, blood tests, and echocardiography. ER was defined either as ST elevation or J wave and categorized according to localization and morphology. Results: One hundred and fifty-one subjects (50 +/- 5 yr) were evaluated before the race, and 47 subjects were evaluated after the race. Altogether, 67 subjects (44%) had ER. Subjects with versus without ER had a lower resting HR (56 +/- 8 vs 69 +/- 9 bpm, P = 0.02), lower body mass index (24 +/- 2 vs 25 +/- 3 kg.m(-2), P < 0.001), higher training volume (3.0 +/- 2.6 vs 2.1 +/- 2.7 h.wk(-1), P = 0.03), and faster 30-km running times (194 +/- 28 vs 208 +/- 31 min, P = 0.01). Vectorcardiography parameters in subjects with ER showed more repolarization heterogeneity: vector gradient (QRS-T-area) (120 +/- 25 vs 92 +/- 29 mu Vs, P < 0.001), T-area (105 +/- 18 vs 73 +/- 23 mu Vs, P < 0.001), and T-amplitude (0.63 +/- 0.13 vs 0.53 +/- 0.16 mm, P < 0.001); these parameters were inversely related to HR (r = -0.37 to -0.48, P < 0.001). ER disappeared in 15 (75%) of 20 subjects after the race. Conclusions: ER is a common finding in middle-age male runners. This ECG pattern, regardless of morphology and localization, is associated with normal cardiac examinations including noninvasive electrophysiology, features of better physical conditioning, and disappears after strenuous exercise in most cases. These findings support that ER should be regarded as a common and training-related finding also in middle-age physically active men.

  • Heart Rate and Its Variability in Response to Running-Associations with Troponin
  • 2014
  • Ingår i: Medicine and Science in Sports and Exercise. - 0195-9131. ; 46:8, s. 1624-1630
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The objective of this study is to investigate the time course of autonomic tone changes after a first-time endurance running race participation and associations with postexertional high-sensitivity troponin (hsTnT) levels in middle-aged males. Methods: Male (n = 42) first-time long-distance running race (Lidingoloppet 30 km) participants >= 45 yr (50.5 +/- 5) were examined. HR and HR variability (HRV) in the time domain (SDANN) was measured continuously from 2 d before to 4 d after the race using a wireless cardiovascular monitor that also recorded arrhythmia episodes. In addition, subjects were assessed pre- and postrace by medical history and physical examination, 12-lead ECG, blood tests including hsTnT, and echocardiography. Results: Compared with corresponding prerace values, nighttime (2: 00-4: 00 a.m.) HR was significantly elevated (63.6 +/- 9.4 vs 53.9 +/- 8.3 bpm, P < 0.001) on the first night postrace, whereas HRV remained reduced for a median of 64 h (interquartile range, 51-102 h). A prolonged HR recovery period (r = 0.48, P = 0.005) and a larger reduction in postrace HRV (r = -0.49, P = 0.003) correlated with higher postrace hsTnT levels. The association between reduced HRV and higher hsTnT remained significant after multivariate analysis (A = -0.48, P = 0.01). No sustained ventricular arrhythmias were recorded, but atrial fibrillation occurred in two subjects. Conclusion: Endurance running race participation caused a prolonged alteration of autonomic tone. More marked and prolonged changes were associated with higher levels of hsTnT, suggesting that the magnitude of troponin increase after strenuous exercise may reflect the magnitude of exercise-induced cardiovascular stress.
