    Item analyses of Turkish Society of Cardiovascular Surgery Board 2015 written exam [Türk Kalp ve Damar Cerrahisi Derneği Yeterlik Kurulu 2015 yazili sinavi madde analizleri]
    (Baycinar Medical Publishing, 2015) Şahin H.; Atay Y.; Yağdi T.; Aka S.A.
    Background: This study aims to analyze the items of the recent board written exam conducted by the Turkish Society of Cardiovascular Surgery and develop recommendations on key issues to prepare a superior exam set for future exams. Methods: In the study, items of the recent board exam, which was held in Eskişehir on April 12, 2015, were analyzed in terms of difficulty, discrimination, and validity. Results: It was detected that correct answer items were distributed equally in the exam set, the average rate of questions answered correctly was 63.79%, 59% of the questions were answered correctly above average, and range of exam scores was wide. Rate of questions with desired difficulty index level was 51% and rate of questions with desired discrimination index level was 76%. Of the questions, 9% was invalid while 66% had a high level of validity. Conclusion: Board written exam seems to be a valid test since exam questions cover all topics in the field of expertise, and the number of questions and rate of valid questions are high. The proportion of those successful in the exam was high and candidates were entitled to take the next step. It is assumed that candidates will be successful in the next phase.

    Learning styles and learning approaches: How closely are they associated with each other and do they change during medical education? [Öğrenme stilleri ve öğrenme yaklaşımları: Birbirleri ile ilişkili mi ve tıp eğitimi sırasında değişiyor mu?]
    (Marmara University, 2017) Bat A.H.; Yilmaz N.D.; Yağdi T.
    Objectives: This study aims to determine medical students’ learning styles and approaches and to evaluate the relationship between them, as well as observe whether any changes occur in these during the course of their education. Methods and Materials: This research was carried out on students who were enrolled in 2008-2009 and was conducted in their first, second and fourth years. The study group consisted of students who had fully completed the scales of measurement used for this research in all years. Learning styles and approaches were determined for each period. Results: An increase in the convergent and divergent styles and a decrease in the assimilator style, determined over the years were not statistically significant. The decline in the deep learning approach scores was important. Evaluating the relationship between the learning styles and approaches, we found that the deep learning approach scores with the divergent style were lower in the first two years; however, no relationship was observed in the fourth year. Conclusions: The learning style follow-up study indicates a trend among students who will try to understand the whole by giving importance to details, to focus on problem solving, and to move away from traditional learning. The decrease in deep learning approaches may be linked to the nature of assignments and testing systems. © 2017, Pacini Editore S.p.A. All rights reserved.

    New conduction defects and pacemaker implantation after heart transplantation
    (Baycinar Medical Publishing, 2015) Engin C.; Ertugay S.; Kemal H.S.; Şahin H.; Yağdi T.; Engin Y.; Akdemir I.; Nalbantgil S.; Özbaran M.
    Background: This study aims to determine the incidence of new conduction defects and pacemaker implantation and to identify patient characteristics for a permanent pacemaker need after biatrial orthotopic heart transplantation. Methods: B etween F ebruary 1 998 a nd A ugust 2 014, w e retrospectively analyzed the data of 212 consecutive patients (147 males, 65 females; mean age 39.6±15 years; range 5 to 65 years) who underwent heart transplantation with biatrial cuff technique in our clinic. Baseline characteristics and postoperative data were compared among the patients who required a pacemaker or did not. Results: The incidence of permanent pacing after heart transplantation was 6.4%. The most frequent reason for permanent pacing was symptomatic bradycardia. Previous cardiac surgery was associated with a non-significant trend toward a need for permanent pacing (p=0.056). The presence of a ventricular assist device was a found to be associated with both prolonged temporary and permanent pacemaker requirement after biatrial cardiac transplantation (p=0.021 and p=0.042, respectively). Conclusion: Although bradyarrhythmia and need for temporary pacing were common in the early postoperative period, few of these patients needed permanent pacemaker implantation. The need for a permanent pacemaker seems to be more frequent after challenging operations, such as bridge to heart transplantation with a long-term ventricular assist device.

    Türk Kalp ve Damar Cerrahisi Derneği Yeterlik Kurulu 2016 yazili sinavi madde analizleri [Item analyses of 2016 written exam of Turkish Society of Cardiovascular Surgery Proficiency Board]
    (Baycinar Medical Publishing, 2017) Şahin H.; Atay Y.; Yağdi T.; Aka S.A.
    Background: This study aims to evaluate the item analyses of the 2016 written exam of Turkish Society of Cardiovascular Surgery Proficiency Board and conduct yearly comparisons. Methods: The last of the written exams, which are performed annually, were held in Eskişehir in May 2016. The exam items were analyzed in terms of difficulty, discrimination, and validity. Results: Correct answer items were distributed equally. The average percentage of questions answered correctly was 70.7%. Of the questions, 56% were answered above the average. Range of exam scores was narrower compared to last year's exam. According to the item analysis; rate of questions with the desired difficulty level was 39%, rate of questions with the desired discrimination level was 52%, rate of invalid questions was 54%, and rate of questions with high level of validity was 9%. A comparison of the exams of years 2015 and 2016 revealed that the latter exam was easier, had low discrimination, and weaker validity. Conclusion: According to our findings, subject areas and number of questions in the exam set were effective on the validity of the exam. At least 70% of the questions in the exam set should include the main topics of the specialty and the number of questions should not be changed according to years. With the Proficiency Board forming a question bank and keeping the questions with high validity in the bank, the exam may become more qualified over the years. © 2017 All right reserved by the Turkish Society of Cardiovascular Surgery.
