Scientific research in public health institutions of the City of Buenos Aires

Hospitals with academic activities offer better services to their patients. The Government of Buenos Aires City (GBAC) has an important network of health facilities, but there is little information regarding their academic activities. Our aim was to estimate the proportion of articles included in MEDLINE originated in GBAC hospitals, to evaluate their contribution regarding the whole country (Argentina), and to describe some characteristics of these papers. It is a cross-sectional study based on a MEDLINE search, using the name of each of the 33 GBAC hospitals in the "affiliation" field. Among 22 million references, 1781 belonged to GBAC hospitals (4.4% of all references from Argentina); 66.5% were in English, 83.7% were related to humans, 30.1% were from the last 5 years, 8.3% included high level scientific evidence research (meta-analysis or randomized controlled trials), and 31.1% included research in children. Regarding the rest of the references from Argentina, those from GBAC hospitals included less papers in English (66.5% vs. 90.0%; OR: 0.22; p < 0.0001), less recent papers (30.1% vs. 34.6%; OR: 0.81; p < 0.0001), more research in humans (83.7% vs. 37.3%; OR: 8.65; p < 0.0001), more randomized controlled trials (8.0% vs. 2.8%; OR: 2,9; p < 0.0001), and more research in children (31.1% vs. 9.2%; OR: 4.44; p <0.0001). GBAC hospitals contributed with 4.4% of references attributed to Argentina in MEDLINE. References from GBAC hospitals were less recent, and included more randomized controlled trials and research in children.
