Abstract
Background: Scientific innovation is often achieved through the intersection of ideas from different fields. However, barriers prevent non-epidemiologists from cultivating interests in epidemiology or undertaking epidemiologic work. In this study, we evaluated changes in the diversity of research topics in an epidemiologic journal over time. We aimed to understand how epidemiologists and non-epidemiologists communicate about epidemiologic data and how this impacts innovation in the field.Methods: We categorized the topics of articles published in the Journal of Epidemiology during the early and late 2010s based on their titles. We calculated the Shannon–Weaver diversity index (H′) to measure changes in the diversity of topics addressed by published articles.Results: Comparing 2011–2013 with 2017–2019, there was no significant change in the diversity of article topics (H′ = 4.25 and 4.21, respectively) published in the Journal of Epidemiology.Conclusion: To encourage healthcare providers and public administrators to conduct or comment on epidemiologic studies, epidemiologists should present their findings in easily understood language with appropriate and relevant statistical indicators and useful illustrations. Bringing experience from other specialties into epidemiology may yield new findings from epidemiologic data because of the exposure of non-epidemiologists to different values, workplaces, and occupations. Collaboration among professionals from varied backgrounds and with varied occupational experiences may help to promote scientific innovation by broadening perspectives. In addition, a range of professional experiences may enable individuals to solve difficult research questions more easily by themselves.
Highlights
Innovation in science is often achieved when new ideas and technologies come together [1]
Estimates of diversity using the Shannon–Weaver index were similar for the two periods: 4.25 for 2011–2013 and 4.21 for 2017–2019
Creativity and idea-driven thinking that understands the needs of public health and the general population is needed for life-long employment. This means that epidemiologists may need to work with colleagues with different values and even change workplace several times over their lives
Summary
Innovation in science is often achieved when new ideas and technologies come together [1]. In epidemiology, this may occur when people from diverse backgrounds read or are involved in a study [2]. The same phenomenon is observed in Western countries; as a result, the strategy for solving clinical issues is often expected to arise from a single idea [6]. The degree of innovation in epidemiologic studies may be limited when professionals conform to cultural norms and associated values. Scientific innovation is often achieved through the intersection of ideas from different fields. We aimed to understand how epidemiologists and non-epidemiologists communicate about epidemiologic data and how this impacts innovation in the field
