PubMed reflects linear increase in ophthalmology publications

The number of ophthalmology articles published and recorded in PubMed from 1998 to 2012 significantly increased in linear progression for both adult and pediatric ophthalmology topics, according to a study.
“We found that there was a linear increase in publications over the study period in both pediatric and adult publications. However, the rate of increase was faster for adult publications (multiplication factor of 1.88) than for pediatric publications (multiplication factor of 1.66),” Michael Mimouni, MD, and colleagues said in the study.
In 2012, pediatric ophthalmology articles numbered 20,759 and adult ophthalmology articles numbered 54,270, according to the study. The authors attributed the greater increase in adult ophthalmology articles to an increase in number of journals published, whereas number of pediatric ophthalmology journals published has remained the same.
The investigators specifically tested for a relationship between the linear increase and the selected categories of clinical trials, editorials, letters, meta-analyses, practice guidelines, randomized controlled trials, reviews, systematic reviews and case reports.
Articles published on clinical trials were the most significantly increased overall, whereas the increase rate in randomized clinical trials articles was only significant in adult ophthalmology.
“Our findings show that practicing ophthalmologists who are willing to update their knowledge in a thorough and complete fashion ... might become more dependent on search engines and reviews to remain informed.” the authors said. - by Kate Sherrer
