Measuring Scientific Impact With the h-Index: A Primer for Pathologists

Area of Science:

• Bibliometrics and Scientometrics
• Research Evaluation

Background:

• The h-index is a widely used metric to quantify the productivity and citation impact of researchers.
• It serves as a tool for assessing individual and group scientific performance in academic and research settings.

Purpose of the Study:

• To provide a comprehensive description of the h-index as a measure of scientific output.
• To elucidate the methodology behind the h-index calculation and its applications in research evaluation.

Main Methods:

• The h-index is calculated based on the number of publications and the number of citations each publication has received.
• It can be applied to individuals, university departments, and research institutes for performance evaluation.

Main Results:

• The h-index offers an objective and quantitative measure of scientific contribution.
• However, it has limitations, including not accounting for authorship position, co-authorship, or self-citations.
• Several alternative bibliometric indices have been developed to address these deficiencies.

Conclusions:

• The h-index is a valuable tool for assessing scientific output but should be used with an understanding of its limitations.
• Pathologists and clinical laboratory scientists should be aware of the h-index, as it may influence professional advancement decisions.
