[Nursing in Intensive and Coronary Care. Bibliometric analysis of 180 original articles].
BACKGROUND
Analyze the "original" type articles published in Spain within the field of Intensive and Coronary Care Nursing with bibliometric methodology.


METHODS
A total of 180 articles classified by different journals as original were analyzed. The following information was collected: year of publication, journal, number of authors per article, analysis of thematic by subject and sub-theme, statistical procedure used and references as well as existence or not of institutional collaboration and territorial origin of the articles.


RESULTS
Compliance of Price Law, obtaining duplication rate of 2.16 years. The Journal Enfermería Intensiva is the Nucleus of Bradford. The mean number of authors per article is 4.82. The type of original used most is cross-sectional cut (47.22% of the total), followed by qualitative type (22.78%). The subject matter studied most was psychology (23.3%), followed by respiratory (15.6%). The statistics used most was descriptive (percentage, median and standard deviation), followed by inferential (parametric test, 67.79% and non-parameter test in 23.31%). Crude rate of references to journals was 12.93, and to books, 3.06. In English, it was 10.94, and in Spanish, 7.53. A total of 73.9% of the articles were written without any collaboration and in 19.44% of them, there was collaboration between the hospital site and university. The most product hospital site was the Clínica Universitaria de Pamplona (7.22% of the total), the University Nursing School that of the University of Navarra (10 articles), the province, Barcelona (25.14%), and the Regional Community that of Catalonia, with 26.23% of the total.


CONCLUSIONS
Intensive and Coronary Care Nursing is a young discipline with a growth model that complies with the Price Law and rapid growth rhythm. The Nucleus of Bradford of the journals is made of by Enfermería Intensiva. The mean number of authors per article is elevated in comparison with other fields of Nursing, although less than foreign nursing studies. There is a significant deficit in the number of crude references per article used, with predominance of the English language and journals. The limited existence of institutional collaboration makes us consider a still non-established discipline, although with an ascending clear tendency in recent years.
