Publication Productivity for Academic Ophthalmologists and Academic Ophthalmology Departments in the United States: an Analytical Report

Abstract

Purpose Quantifying scholarly output for academic ophthalmologists and academic ophthalmology departments provides a benchmark for academic productivity, offering information about how well an academic department facilitates the scholarly activity of its faculty. Bibliometrics is a statistical method to analyze scientific literature. Among benchmarking methods, the h-index has been the most widely accepted. The h-index samples a researcher's publication quantity while controlling for quality through citation count. The m-quotient adjusts the h-index according to the number of years since the first peer-reviewed publication, allowing for productivity assessments independent of career length. This study utilizes bibliometrics to create profiles for academic ophthalmology in the United States. Methods Bibliometric profiles were created for 2,824 ophthalmologists from 110 nonmilitary departments. Profiles included the h-index and m-quotient calculated from an online citation database. Comparisons between academic rank, gender, region, and subspecialty were performed. Departments were ranked by the summation as well as the mean of h-indices for each faculty member. Results The mean h-index and m-quotient were 10.56 ± 11.96 and 0.52 ± 0.44, respectively. Both of these values exhibited a positive relationship with increasing academic rank (p Conclusion This report benchmarks the publication productivity of academic ophthalmologists and academic ophthalmology departments in the United States. These results may serve program development in academic ophthalmology departments and prospective trainees and faculty.
