Abstract

Objective To describe the research hotspots and authors’ cooperative relationships in the field of pharmacoepidemiology mentioned in the 2022 International Conference on Pharmacoepidemiology and Therapeutic Risk Management (ICPE), and compare with those result of ICPE 2021.

Methods Taking the 2021—2022 ICPE abstracts as the data source, we used Python to extract literature information. R software networkD3 package was used to draw network diagrams of cooperative relationships among authors and organizations. Term frequency - inverse document frequency technology in tidytext package was used to conduct weighted statistics on the frequency of tokens to identify hotspot diseases, drugs, databases, etc.

Results 2 086 ICPE abstracts were included. Between 2021 and 2022, the number of abstracts, authors, and organizations increased by 58.8%, 42.3%, and 24.9% respectively. In 2022, there were a total of 387 core authors (including 14 from China, all from Hong Kong and Taiwan district), forming 26 close cooperation groups (including 2 Chinese groups). 161 core organizations (including 8 in China), constituted 18 close cooperation groups (including 1 Chinese-foreign group and 1 Chinese domestic group). The topic of COVID-19, type 2 diabetes, and rheumatoid arthritis have always been deeply discussed, meanwhile, the discussion popularity of breast cancer, Parkinson's disease and dementia have increased significantly. Opioids, sodium-glucose transporters 2 inhibitors, and antipsychotics have always been popular drugs, and the popularity of antidepressants, COVID-19 vaccines and antihypertensive drugs have increased markedly. The hotspot databases included Clinical Practice Research Datalink, IBM MarketScan Commercial Claims and Encounters, and Food and Drug Administration Adverse Event Reporting System, etc.

Conclusion From 2021 to 2022, the scale of ICPE has expanded, and academic cooperation has become more extensive and in-depth. However, there is still a big gap between the participation and cooperation scale of scholars from Chinese mainland and foreign countries. Breast cancer, Parkinson's disease, dementia, antidepressants, and COVID-19 vaccines are new hot topics at ICPE 2022. The research hotspots and cooperation networks displayed in this article have certain reference values for Chinese pharmacoepidemiologists in selecting future research topics and partners.
