Pub Med and Google Scholar perspectives of the Ceylon Medical Journal: Analysis from 2002 - 2016

Abstract

INTRODUCTION: Revisiting our analysis published in 2002, a bibliometric analysis of the Ceylon Medical Journal(CMJ) was done. METHOD: CMJ citations from 2002-2016 were downloaded in PubMed/MEDLINE format and written to a MS• Access database using 'PubMed Grabber' software from Kelaniya. For analysis, advanced PubMed queries and Google Scholar (for H-Index and cross-check author publication details) were used. RESULTS: 87~ citations were authored by 1666 authors. However, only 441 had more than one citation. Annual citations decreased from 71 (2002) to 61 (2016). Range 51-71, mean 58.6 and mode 51. Publications types: Journal Articles 685 (75%), Case Reports 281 (32%), Letters 210 (24%), Reviews 19 (2%), Clinical Trials 25(3%). Classification of citations by ICD-10 main chapters using Medical Subject Headings [MeSH]: infections and parasitic 156 (17.7%), endocrine, nutritional and metabolic 119 (13.5%), neoplasms 111 (12.6%), nervous system 101 (11.5%), digestive system 90 (10.2%). Authors with the highest number of articles were: [CMJ articles in PubMed, All articles in PubMed, H-Index] de Silva HJ [30,150,41] Lamabadusuriya SP [22,26,4] Pathmesweran A [22,64, 17] Senanayake MP [18,28, 9] de Silva NR (17,45,26] Kuruppuarachchi KA [16,24,7] Jayasinghe-_S_ [ 16, 189, 19] . CONCLUSION: The number of annual citations in CMJ is decreasing. For 1225 (73%) authors, publishing in the CMJ was a one-time affair. Case reports (32%) and letters (24%) totalled 56%. The vast majority of the top ranked CMJ authors had more citations in journals with a higher 'journal impact-factor' than CMJ. This may be one reason that CMJ is yet to have an impact-factor. Our method depends on the accuracy and consistency of author name, affiliation, and the key words submitted by authors.
