Abstract: OBJECTIVE: To analyze the network structure of collaboration 
between medical centers sharing authorship of scientific articles on 
smoking.

MATERIAL AND METHODS: Articles reporting smoking research by authors from 
2 or more Spanish medical centers between 1999 and the end of 2003 were 
identified through the Science Citation Index. The network of 
collaboration behind the research was analyzed and the most important 
measures of centrality were compared. To display the data, scientometric 
maps were constructed using UCINET and NETDRAW network analysis tools.

RESULTS: Thirty-five Spanish medical centers (29 hospitals and 6 health 
care clinics) in 8 autonomous communities were involved in 21 
collaborative research projects. Hospital de La Princesa was the network 
core institution with the highest degrees of nodal (16), closeness 
(88.66), and betweenness (39) centrality. Other core nodes in the network 
were the following hospitals: de Cruces, San Pedro de Alcantara, La Paz, 
Vall d'Hebron, and General Yague. The autonomous communities of Castile 
and Leon, Madrid, and Catalonia were assigned positions at the core of the 
intercommunity collaborative network based on coauthorship of scientific 
papers shared among their medical centers.

CONCLUSIONS: Network analysis helps identify the most influential 
institutions in a scientific community that generates coauthored articles 
in the field of smoking research. Hospital de la Princesa had the highest 
measures of centrality. The autonomous communities of Castile and Leon, 
Madrid, and Catalonia form a highly connected, cohesive subgroup within 
the network.
