HEMS Outcomes Research Database

The newly developed HEMS Outcomes Assessment Research Database is currently comprised of data from 221 studies focusing on outcomes in HEMs. Databases were searched on 10th January 2023, for articles published from 1970 through 2022. Searches included databases of traditional and gray literature. The primary search database was that of the NLM, accessed at PubMed.gov: https://pubmed.ncbi.nlm.nih.gov. This search yielded 27,207 results (records). The main secondary search database, EMBASE, provided 15,097 records. All of these records were reviewed by title and (where necessary) by abstract, to identify records warranting further examination. A review of titles and (where necessary) abstracts identified a total of 221 records that warranted more detailed evaluation (i.e., reported comparative HEMS vs. GEMS survival). The intention of this session is to introduce the database to the air medical community. The 221 HEMS outcomes studies comprised the kernel for a freely available list of publications, the HEMS Outcomes Assessment Research Database, HOARD. The HOARD is managed by the Division of EMS at the authors’ institution as part of the Critical Care Transport Collaborative Outcomes Research Effort (CCT CORE). This session will describe the database development (search process, study selection, storing of data), past and present projects, and future plans for the database.
