    • BACKGROUND:Simulation can be used for educating, evaluating and assessing psychometric properties of an instrument. The aim of this study was to contextualize and assess the validity and reliability of the Interprofessional Collaborative Assessment tool (ICAR) in an Iranian context using simulation.METHODS:In this descriptive study, contextualization of the ICAR was assessed through several steps. Firstly, validity assessment was approved through expert panels and Delphi rounds. Secondly, reliability assessment was done by arranging a simulation video and assessing reproducibility, test-retest (ICC), internal consistency (Cronbach's Alpha) and inter-rater reliability (Kappa).The participants included 26 experts, 27 students and 6 staff of the Standardized Simulation Office of Teheran University of Medical Sciences.RESULTS:Contextualization and validity of the ICAR were approved in an Iranian context. The reliability of the tool was computed to be 0.71 according to Cronbach´s Alpha. The test-retest was calculated to be 0.76.CONCLUSION:The Iranian ICAR can be a useful tool for evaluating interprofessional collaborative competencies. The development of the instrument through a simulation scenario has been a positive prospect for researchers.

  • Stress among medical students during clinical courses : a longitudinal study using contextual activity sampling system
  • 2019
  • In: International Journal of Medical Education. - : IJME. - 2042-6372. ; 10, s. 68-74
  • Journal article (peer-reviewed)abstract
    • Objectives: To investigate medical students’ experiences of stress and other emotions related to their professional roles, as defined by the CanMEDS framework, by using the Contextual Activity Sampling System (CASS).Methods: Ninety-eight medical students agreed to participate of whom 74 completed this longitudinal cohort study. Data was collected between 6th and 8th term via CASS methodology: A questionnaire was e-mailed to the participants every 3rd week (21questionnaires/measurements) during clinical rotations and scientific project work term. Emotions were measured by a 7-point Likert scale (e.g., maximum stress = 7). Answers were registered through mobile technology. We used a linear mixed-model regression approach to study the association between stress over time in relation to socio-demographic and learning activities related to CanMEDS roles.Results: Participants completed 1390 questionnaires. Mean stress level over all time points was 3.6. Stress was reported as highest during the scientific project term. Learning activities related to ‘Communicator,’ ‘Collaborator,’ ‘Scholar,’ ‘Manager’ and ‘Professional’ were associated with increased stress, e.g. ’Scholar’ increased stress with 0.5 points (t=3.91, p<0.001). A reduced level of stress was associated with ’Health Advocate’ of 0.39 points (t=-2.15, p=0.03). No association between perceived stress and demographic factors, such as gender or age was found.Conclusions: An association between different learning activities related to CanMEDS Roles and feelings of stress were noted. The CASS methodology was found to be useful when observing learning experiences and might support educational development by identifying course activities linked to stress.

  • Quality of life and clinical outcome after anterior cruciate ligament reconstruction using patellar tendon graft or quadrupled semitendinosus graft: an 8-year follow-up of a randomized controlled trial
  • 2010
  • In: The American journal of sports medicine. - : SAGE Publications. - 1552-3365 .- 0363-5465. ; 38:8, s. 1533-1541
  • Journal article (peer-reviewed)abstract
    • Background: Randomized controlled trials after anterior cruciate ligament reconstructions with long-term follow-up including assessment of health-related quality of life are rare.Purpose: To compare clinical outcome and health-related quality of life 8 years after anterior cruciate ligament reconstruction using 2 types of graft.Study Design: Randomized controlled trial; Level of evidence, 1.Methods: Long-term follow-up of 164 patients with anterior cruciate ligament injury randomized to arthroscopic reconstruction with a quadrupled semitendinosus graft or a bone–patellar tendon–bone graft was undertaken. After a mean 8 years, 153 patients were available for follow-up, including instrumented laxity, 1-legged hop test, a knee-walking test, and assessment with International Knee Documentation Committee, Lysholm, Tegner, and patellofemoral pain score. Health-related quality of life was assessed with Knee Osteoarthritis Outcome Score and Short Form–36.Results: Patients in both graft groups retained the same stability, knee function, and health-related quality of life. The patellofemoral pain score was similar for both groups; the bone–patellar tendon–bone group had more donor site morbidity from kneeling and knee walking. In the bone–patellar tendon–bone group, 19 patients had no kneeling problems, 23 slight problems, 31 moderate problems, and 5 unable to kneel. Corresponding figures for the semitendinosus group were 25, 32, 16, and 2 ( P < .001). Patients with early reconstructions (<5 months) had a lower risk for meniscal injuries (37%) than did later reconstructed (62%, P = .008). Health-related quality of life regarding physical functioning in Short Form–36 was better for the early-reconstructed patients than for the later reconstructed (92 vs 85; P = .014). Patients without medial meniscal surgery had higher Knee Osteoarthritis Outcome Scores for all subscales than did patients with medial meniscal surgery, with most significant difference for sport and recreation (63 vs 75, P = .008).Conclusion: In the long term, the semitendinosus graft provided similar stability, knee function, and health-related quality of life but with less kneeling morbidity than did the bone–patellar tendon–bone graft.

    • Barenius B, Nordlander M, Ponzer S, Tidermark J, Eriksson K. Quality of life and clinical outcome after anterior cruciate ligament reconstruction using patellar tendon graft or quadrupled semitendinosus graft: an 8-year follow-up of a randomized controlled trial. Am J Sports Med. 2010;38(8):1533-1541. (Original DOI: 10.1177/0363546510369549) In the above article, There is an error in Table 1 (page 1535). In the 3rd row of data, which shows gender distribution in the graft groups, the percentage for male distribution in the whole study population was depicted instead of the percentage of male distribution in the specified graft groups. The data for number of male patients in the groups are correct, and the error does not influence any of the other results.

  • Health related quality of life, reoperation rate and function in patients with diabetes mellitus and hip fracture-A 2 year follow-up study
  • 2013
  • In: Injury. - : Elsevier BV. - 0020-1383 .- 1879-0267. ; 44:6, s. 769-775

    • Introduction: Diabetes mellitus confers an increased risk of hip fractures. There is a limited knowledge of how the outcome after a hip fracture in patients with diabetes affect Health Related Quality of Life (HRQoL). The primary aim of this study was to evaluate HRQoL. Secondary aims were reoperation rate, complications and functions in patients with diabetes followed for 2 years after a hip fracture. Materials and methods: Out of 2133 patients diabetes was present in 234 patients (11%). Main outcome measurements were HRQoL evaluated with EuroQoL 5-D-index score, reoperation rate, surgical and medical complications, function as walking ability, daily activities, living condition and pain. Results: Preoperatively, patients with diabetes mellitus had more pain (p = 0.044), co-morbidities, reduced health status (p = 0.001) and more often used a walking frame (p = 0.014) than patients without diabetes, whereas Katz ADL index, cognition and body mass index did not differ. There was no difference in fracture type, surgical method or reoperation between the two groups or between patients with insulin treated or oral treated diabetes. The EQ-5D(index) score decreased from 0.64 at admission to 0.45 at 4 months, 0.49 at 12 months and 0.51 at 24 months with similar results for patients with and without diabetes. During the first postoperative year there was not more medical complications among patients with diabetes, however cardiac (p = 0.023) and renal failure (p = 0.032) were more frequent in patients with diabetes at 24 months. Patients with diabetes more often had severe hip pain at 4 months (p = 0.031). At 12 months more diabetic patients were living independently (p = 0.034). There was no difference in walking ability, ADL and living condition between the groups at 24 months. Conclusion: The findings of this study indicate that patients with diabetes mellitus had more pain, co-morbidities, reduced health status preoperatively than patients without diabetes. Hip fracture patients with diabetes mellitus have more hip pain at 4 months. Cardiac and renal failure was more frequent in patients with diabetes at 24 months but otherwise we found a comparable re-operation rate, function and deterioration of Health Related Quality of Life as patients without diabetes within 2 years after a hip fracture.
