Perceptions and Use of PubMed and the MeSH Thesaurus among Postgraduate Medical and Dental Trainees in Health Information Retrieval

The study mainly focused on the usage of PubMed and the MeSH (Medical Subject Headings) thesaurus during the health information retrieval process. The study investigates the level of awareness, utilisation patterns, and potential benefits of use of the Medical Subject Headings (MeSH) Thesaurus in the retrieval of information of postgraduate medical and dental trainees. It also investigated the trainees‘ perceptions, attitudes, and satisfaction regarding the MeSH thesaurus help tool. Using a descriptive survey design, data was collected from postgraduate trainees enrolled in the PGIM Library Orientation Programme between 01st January 2025 to 30th May 2025. The main data collection instrument was a questionnaire, which was administered through Google Forms.
A mixed-method approach was implemented using both quantitative and qualitative analyses. Findings revealed a moderate level of familiarity with MeSH yet its usage in literature searches remained low. A significant percentage of trainees were unaware of MeSH guidance, but the majority expressed a willingness to adopt it if adequately supported. Confidence in information retrieval was significantly associated with experience levels. Most of the respondents acknowledged the benefits of MeSH thesaurus, emphasizing enhanced relevance ease of use improved accuracy and time efficiency. The study highlights the importance of applying the MeSH tool in information retrieval and providing structured training programs. Key recommendations are threefold: implement mandatory training workshops; provide guidance on how to make use of MeSH tools (e.g., a thesaurus browser and query builder) during search processes through existing health information retrieval platforms to create a more guided search experience; and enhance curricular focus on database proficiency. The goal of the present study is the optimization of the usage of health information retrieval systems available for postgraduate medical and dental trainees through the PGIM Library.
