This article reports a bibliometric analysis of emerging topics in the psychiatric literature indexed in the MEDLINE database as a technique for renewal of clinical training curricula. Summary data of English-language articles indexed in the MEDLINE database between 1971-2018 were downloaded. Emerging topics in nine demi-decades between 1972-1976 and 2012-2016 were identified by the incremental incidence of individual Medical Subject Headings (MeSH) compared with previous years. Co-word analysis was used to investigate and visualise the relationships between emerging topics in each demi-decade. Summaries of 18 million articles annotated with psychiatric/psychological MeSH were retrieved and used to identify emerging topics. Peaks in the number of articles annotated by the top 20 emerging topics in 9 demi-decades coincided with release of the third and fourth editions of the Diagnostic and Statistical Manual which codifies psychiatric diagnoses. Themes emerging from network visualisations of the most common emerging MeSH in each demi-decade were consistent with movements in psychiatric/psychological theory and practice since the 1970s, including the recent focus on psychological and social factors implicated in suicide and suicide prevention. The identification of emerging topics within the published medical literature is a viable technique for use in curriculum renewal projects as a counterweight to biases driven by expert judgement. While indices like MEDLINE make the published literature an appealing initial step in building an empirical basis for curriculum development, it also demonstrates the potential value of less public and less structured data, such as health service electronic medical records.
