3. 31-05-20163 ■ The scientific publication is a key-step in every investigation project ■ It represents the step where results are submitted to the public scrutiny Reasons to write

4. 31-05-20164  In Medicine and independently from the outstanding results obtained, the task won’t be complete till those results are published  In a first instance do good science, then publish good science “a naturalist´s life would be a happy one if he had only to observe and never to write” Charles Darwin Reasons to write

5. 31-05-201655 Introduction ■Bibliometry together with peer-review has been used to assess and quantify the importance of authors and scientific investigations

6. 31-05-20166 6 Introduction ■Bibliometric studies based on data from scientific publications have shown a growing development in the most advanced countries in the last years ■In Portugal there are few studies of that type, at least in the field of biomedicine  Donato HM, De Oliveira CF.

7. 31-05-20167 7 Bibliometry ■ What is Bibliometry?  A science which enables quantitative and qualitative analysis of the scientific production through evaluation of the produced literature ■ What does it study?  Authors  Subjects  Journals  Departments  Countries

8. 31-05-2016Actualizações em Oncologia 20088 Bibliometry Resources ■The widest used resource of bibliometry is the one produced by Thomson Scientific (Institute for Scientific Information), the Web of Science (WOS) ■It evaluates articles published in more than 8700 journals ■It also publishes an yearly Index (Journal Citation Reports) based on the cited articles

9. 31-05-20169 9 Objectives This study deals mainly with : ■ The contribution of portuguese authors to the international scientific production in the specific area of Obstetrics & Gynecology ■ The analysis of the scientific production during the period from 1997 to 2006

10. 31-05-20161031-05-201610 Objectives ■Using compiled information, the following indicators were calculated :  Quantitative  Qualitative

11. 31-05-20161131-05-201611 Quantitative Indicators ■ Productivity rate of institutions ■ Productivity rate of authors ■ Growth of national production in international publications

12. 31-05-20161231-05-201612 Qualitative or Impacting Indicators ■Influence and visibility of scientific production (Impact Factor) ■The widest used bibliometric indicators in the assessment of quality of scientific activity are based on:  The number of citations received by the published articles  The importance / impact of the journals where they were published

13. 31-05-20161331-05-201613 Data Collection ■ The study was performed using the Databases  Web of Science (WOS) - http://isiknowledge.comhttp://isiknowledge.com  Medline / Pubmed – http://www.pubmed.govhttp://www.pubmed.gov ■Have not considered publications in national journals, since none of the journals published in Portugal is included in Journal Citation Reports

14. 31-05-20161431-05-201614 Search ■ We collected all documents published between 1997 and 2006 about our thematic, where at least an author belongs to a portuguese institution ■We considered all articles, independently from its tipology (revisions, clinical trials, letters, editorials…)

15. 31-05-20161531-05-201615 Results ■WOS + PubMed = 846 articles ■747 articles published in Journals with Impact Factor ■Our study is based upon the analysis of the 747 IF articles

16. 31-05-20161631-05-201616 Results ■The portuguese scientific contribution to the international scientific production in the field Obstetrics & Gynecology during the studied period, showed a growth of 144%

18. 31-05-20161831-05-201618 Productivity of Portuguese Authors ■Parameter distribution by Author:  Seven authors account for 37% of the documents, contributing thus with more than 20 articles  Twenty seven authors account for 46,8% of the documents, with more than 10 articles  Others with 10 or less articles account 16,2%

19. 31-05-20161931-05-201619 Co-authorship ■In biomedicine, the rule is co-authorship in publications; portuguese authors follow this international trend ■The co-authorship rate exibits an increase during the years ■Slight increase in the average number of authors by document

20. 31-05-20162031-05-201620 Qualitative Analysis of Results ■The analysis of qualitative data from scientific literature enables the assessment of:  The yield of scientific activity and its impact on the community  The impact of the whole of the portuguese scientific production in the area Obstetrics & Gynecology determined by the number of citations obtained by published articles

21. 31-05-20162131-05-201621 Citation Report ■Total 747 articles ■Sum of the Times Cited – 7,989 ■Average Citations per Item – 10.96
