Since its publication in 2001, the National EMS Research Agenda has brought attention to a relative paucity of emergency medical services (EMS)-specific research and has called for an increase in funding and infrastructure to support EMS research. We investigated the trends in EMS-specific publications and National Institutes of Health (NIH)-funded research grants in the 20 years since this landmark publication.
We performed a structured PubMed search of English-language citations from 2001 to 2020 to identify publications with populations, settings, or topics related to EMS care, education, or operations. Publications in trade journals and studies not involving humans were excluded. We also queried NIH Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER) using a similar structured search. Titles, keywords, and abstracts were reviewed. Descriptive statistics were calculated, and nonlinear trends were described using segmented regression models.
A total of 183,307 references met the search criteria in PubMed, and 4,281 grants were identified in NIH RePORTER. After removing duplicates, 152,408 titles were screened, with 17,314 (11.5%) included. EMS-related publications increased from 419 in 2001 to 1,788 in 2020, a 327% increase, compared with a 197% increase in total PubMed publications. There was a statistically significant nonlinear (J-shaped) increase in EMS publications after 2007. There were 1,166 funded EMS-related NIH grants, with a 469% increase from 2001 to 2020 compared with an 18% increase in overall NIH awards.
Although total publications have doubled in the United States over the past 20 years, EMS-specific research has more than tripled and the number of funded EMS research grants has increased nearly 5-fold. Future evaluation should examine the quality of this research and its application to clinical practice.
自 2001 年《国家紧急医疗服务研究议程》发布以来，人们开始关注紧急医疗服务（EMS）特定研究相对较少，并呼吁增加资金和基础设施，以支持 EMS 研究。我们调查了自这一具有里程碑意义的出版物发布以来的 20 年中，EMS 特定出版物和美国国立卫生研究院（NIH）资助的研究赠款的趋势。
我们在 2001 年至 2020 年期间对英文文献进行了结构合理的 PubMed 搜索，以确定与 EMS 护理、教育或运营相关的人群、环境或主题的出版物。排除贸易期刊中的出版物和不涉及人类的研究。我们还使用类似的结构化搜索查询 NIH 研究组合在线报告工具支出和结果（RePORTER）。审查了标题、关键字和摘要。计算了描述性统计数据，并使用分段回归模型描述了非线性趋势。
在 PubMed 中，共有 183307 篇参考文献符合搜索标准，在 NIH RePORTER 中确定了 4281 项赠款。删除重复项后，筛选了 152408 个标题，其中 17314 个（11.5%）入选。与 2001 年的 419 篇相比，2020 年与 EMS 相关的出版物增加到 1731 篇，增长了 327%，而 PubMed 总出版物增长了 197%。2007 年后，EMS 出版物呈明显的非线性（J 形）增长。共有 1166 项资助的 EMS 相关 NIH 赠款，与 2001 年至 2020 年相比增长了 469%，而 NIH 总拨款仅增长了 18%。
尽管在过去的 20 年中，美国的总出版物数量增加了一倍，但 EMS 特定研究的数量增加了两倍多，资助的 EMS 研究赠款数量增加了近 5 倍。未来的评估应检查这项研究的质量及其在临床实践中的应用。
