Many users struggle with searching MEDLINE due to challenges with the National Library of Medicine's Medical Subject Headings (MeSH). Improved instruction is needed to help users navigate complex search features and improve retrieval accuracy.

Area of Science:

  • Medical Informatics
  • Library Science
  • Information Retrieval

Background:

  • End-users encounter difficulties when searching MEDLINE, a prominent biomedical literature database.
  • Indexing features within the National Library of Medicine's (NLM) Medical Subject Headings (MeSH) present usability challenges.
  • Existing literature highlights end-user problems with MEDLINE and MeSH searching.

Purpose of the Study:

  • To identify and analyze specific MeSH features that impede effective MEDLINE retrieval for end-users.
  • To underscore the need for enhanced instructional methods to support end-user search strategy formulation.
  • To provide a comprehensive overview of end-user challenges in MEDLINE searching.

Main Methods:

  • Analysis of casual observations, formal consultations, and educational sessions with end-users.

  • Review of existing literature on end-user challenges with MEDLINE and MeSH.
  • Identification of problematic MeSH indexing features impacting search retrieval.

    • Main Results:

    • Key problematic MeSH features include Explodes, Tree structures, subheadings, Text Word vs. subject heading searching, and central concept searching.
    • Increasing sophistication of end-user search software necessitates more detailed instructional approaches.
    • End-users face significant hurdles in formulating effective search strategies within MEDLINE.

    Conclusions:

    • Specific MeSH features require clearer understanding and instruction for optimal MEDLINE searching.
    • Enhanced and detailed educational strategies are crucial for improving end-user information retrieval success.
    • Addressing these challenges can lead to more efficient and accurate access to biomedical information.
