Performance of Chinese medical postgraduate students in literature searching: a two-center survey and analysis

Background: To explore the performance status of Chinese postgraduate medical students in literature searching. Methods: A self-designed online questionnaire was used to assess the literature search performance of postgraduate students (PGSs) from the classes of 2016, 2017, 2018, and 2019 from two medical colleges. The items of the questionnaire mainly included: the demographic characteristics of the PGSs, methods of literature review, literature reading habits, and use of literature. We also designed a self-assessed score that ranged from the lowest 1 point to the highest 5 points. Results: A total of 902 PGSs (482 male, average age: 29.4 +/- 5.8 years old, working time range: 0-10 years, average 3.7 +/- 2.4 years) completed the questionnaire. Most PGSs investigated literature only at the work tasks (632, 70.1%) and writing papers ( 571, 63.3%) stages. Of the PGSs, 542 (60.1%) PGSs searched literature frequency (>= 1 paper/week), and 114 (12.6%) did not perform advanced searches, and some had no knowledge of advanced search techniques at all. Most PGSs had not read more than 100 Chinese articles or English articles before. Most PGSs were used to read articles from the most authoritative journals (665, 73.7%) or high impact factor (IF) (540, 59.9%). PGSs (845, 93.7%) only read the full text of articles they deemed important. Of the PGSs, 441 (48.9%) did not use literature management tools. For self-assessed score of literature searching and reading skills, the mean was 2.1 (standard deviation, 0.8). Reading literature efficiently (710, 78.7%) and tracking recent literatures (615, 68.2%) were the two needed literature skills reported. Conclusions: Chinese medical PGSs still have room for improvement in relation to literature investigation. Intensive training in literature searching should be given to improve their performance.
