Organization of the ISTH in Epidemiology Applied to the Study of Thrombosis and Haemostasis in Belgrade was initiated by Dr. Danijela Mikovic, president of the Serbian Society of Haemostasis and Thrombosis. The course is result of previous successful collaboration between ISTH and Serbian Society of Haemostasis and Thrombosis. Namely, dr. Danijela Mikovic organized ISTH Educational Course in Belgrade in 2012 with the support and collaboration of prof. Flora Peyvandi and prof. Frits Rosendaal. 

After that meeting dr. Biljana Vuckovic, vicepresident of the Serbian Society, received ISTH fellowship award and she spent three months training (May – Aug 2013) at the Leiden University Medical Centre under the supervision of prof. Frits Rosendaal. During this education, besides other activities of great importance for her future scientific and professional work, she made numerous professional contacts. She discussed initial idea about organizing ISTH educational course in clinical epidemiology with colleagues from the Leiden University Medical Center in order to provide benefits to the wider scientific community in Serbia.

After that, with the support of Mr. Cary Clark, Program and Technology Manager of the ISTH, and Lacey Schneider, Program Coordinator of the ISTH, official contact through ISTH with invited speakers was made, their participation was confirmed and presentation topics were defined by colleagues from Leiden University Medical Centre. Besides, date and place of the ISTH course, target audience and age of participant, structure and draft version the program as well as budgeting principles were established.

Application to the ISTH Education Committee was submitted and our proposal together with preliminary program and budget were approved in November 2014.

The following organizational step was to find and delegate participants who are trainees and junior specialists in Internal Medicine, Cardiology, Haematology, Transfusion Medicine, Vascular Medicine, Biochemistry and other medical specialties engaged in  problems of thrombosis and haemostasis and PhDs wishing to acquire biochemical and clinical knowledge in the field of haemorrhagic and thrombotic disorders. In Serbia, selection of participants was made through personal communication with the most relevant institutions, officials and colleagues involved in the field of haemostasis and thrombosis by dr. Danijela Mikovic and dr. Biljana Vuckovic. Contacts with colleagues within the region of South East and Central Europe and colleagues from Russia where achieved thanks to previous cooperation within Danubian League against Thrombosis and Haemostasis. 

CME accreditation was obtained by official Serbian authorities. Accreditation process required submission of necessary documents:

  • Filled in CME accreditation application, signed and sealed by the CE organizer
  • Summary of the education programme 
  • Timetable, topics and list of lecturers 
  • Detailed lecturers’ CVs in the official form provided by the Serbian Health Council
  • Decision made by Education Committee of the International Society of Thrombosis and Haemostas that the Application for the ISTH-supported course has been approved 
  • Intelectual property certificate.

ISTH Advanced Course in Haemostasis and Thrombosis has been accredited by the decree issued by the Health Council of the Republic of Serbia (А-1-122/15).

According to guest speakers, as well as dr. Biljana Vuckovic who also actively participated in the organization of this Course, who expressed their impressions right after the meeting and my personal opinion we succeeded to achieve several goals we anticipated at the beginning.  

We achieved our main goal which was to gather together 30 young participants involved in haemostasis and thrombosis field, most f them from Serbia and several from the other countries of the region and from Russia.

On the other hand, I am grateful for having been enabled to engage highly distinguished invited speakers who presented exceptional and valuable lectures, who transferred their knowledge and experience to younger colleagues.  Many participants expressed their gratitude for having been able to attend this meeting which in their opinion was so far one of the best one they have ever attended.

This meeting was an excellent opportunity for several young doctors to present their research and at the same time they had an extraordinary opportunity to get precious comments and recommendations for their future work from invited speakers.

Each session was followed by constructive discussions which contributed to the overall atmosphere of the meeting which was at the same time highly professional and relaxed, and marked with close and spontaneous interaction between speakers and participants. Invited speakers were also active and inspiring moderators of discussions with participants during the entire course. It stimulated participants to freely communicate with the experts which encouraged very active exchange of opinions.

We succeed in providing industry support without symposia and exhibition and also without their influence on program and choice of participants.

One of the greatest achievements of the meeting is that a regional network of young professionals in haemostasis and thrombosis field has been strengthened. That liaison will certainly show its effects in future through collaboration, mutual projects etc.

As some of the main goals of Serbian Society of Thrombosis and Haemostasis is to improve global knowledge in the field of haemostasis, and to promote the scientific research in this field we succeeded in our idea to provide education by this course that will be precious for professional development of young scientists in our country and thereby for improvement of the quality of health care services in it.

In the end, I would like to express my most sincere gratitude to all three speakers and especially to prof. Frits Rosendaal for his persistent support and valuable suggestions related to the organization of the previous and also this ISTH Course in Belgrade. I would also like to point out important role of Mr. Cary Clark, ISTH Program and Technology Manager and Lacey Schneider, Program Coordinator of the ISTH,  to thank them for selfless  assistance in the course of the meeting preparations. Last but not least, I would like to stress the support and help of my local Meeting Coordinators thanks to whose enthusiasm the meeting was, step by step, finalized and held as anticipated.
