The Spanish research production on Prison Health represents a similar share of the world output similar to that of other disciplines (1.9%), although slightly lower (General Medicine represents 3.05%; Public Health, 2.38%; Psychiatry, 2.29%; Toxicology, 2.46%). It seems likely that this share will increase as a result of the inclusion of its main journal in Medline along with an increasing number of researchers working on this discipline at an international level. However, inclusion has not yet led to integration into high-impact journals or a larger number of citations. The average Journal Impact Factor is relatively low (2.062) and few papers are published in first-class journals (Q1). There are few articles with a good citation average according to the discipline's standard. Likewise, the collaboration pattern still shows a poor state for Spanish research on Prison Health.
