ABSTRACT
BACKGROUND: Since the beginning of the pandemic, new knowledge about COVID-19 obtained by research has been disseminated in medical and scientific journals, but the large number of publications that have been generated in such a short time has been impressive. OBJECTIVE: To perform a bibliometric analysis of the published articles in medical-scientific journals carried-out by the Mexican Social Security Institute (IMSS) personnel on COVID-19. MATERIAL AND METHODS: Systematic review of the literature, identifying the publications included in the PubMed and EMBASE databases, up to September 2022. Articles on COVID-19 were included, in which at least one author had IMSS affiliation;there was no restriction on the type of publication, so original articles, review articles, clinical case reports, etc. were included. The analysis was descriptive. RESULTS: 588 abstracts were obtained, of which 533 full length articles met the selection criteria. Most were research articles (48%), followed by review articles. Mainly clinical or epidemiological aspects were addressed. They were published in 232 different journals, with a predominance of foreign journals (91.8%). Around half of the publications were carried out by IMSS personnel together with authors from other institutions, national or foreign. CONCLUSIONS: The scientific contributions prepared by IMSS personnel have contributed to understanding clinical, epidemiological and basic aspects of COVID-19, which has had an impact on improving the quality of care for its beneficiaries.
