How big is the medical writing industry? Why it matters.

Abstract

Medical writing is a key element in pharmaceutical companies' efforts to shape the relevant medical science literature. As part of what is called 'publication planning', medical writing can influence the knowledge base on which prescribers make decisions, and can build specific claims in targeted sales efforts. Most publication planning is done by hired medical education and communication companies (MECCs), with the rest done by other commercial entities, such as units of pharmaceutical companies or of contract research organizations, that provide essentially the same services as MECCs. Here we provide an estimate of the number of MECCs and comparable entities contributing to the medical science literature in English. To identify these companies, we collected data from Web of Science (858 named firms from 20 498 papers mentioning medical writing assistance), LinkedIn (410 company profiles), and Google and DuckDuckGo (68 company websites). After removing duplicates and false positives, we found 1148 MECCs and other comparable entities providing medical writing services. More than 50% of Web of Science papers that acknowledged medical writing support are sponsored by only ten pharmaceutical companies. Most of the remaining papers in our database are sponsored by other pharmaceutical, device, and biotechnology companies. This study likely undercounts MECCs, because it depends on some level of transparency in publications or other leakage of information. Our combining multiple sources for the data should limit the undercount of MECCs. The study does not identify MECCs that work exclusively in languages other than English.
