Background: Military environmental exposure (MEE) and health information reside across many data sources, requiring extensive time and exposure literacy to extract, collate, and summarize for clinical use. The Health Exposure Records and Occupations (HERO) Summary combines exposure and health information from these different sources into a concise exposure report to improve consistency and efficiency in exposure-informed care. However, understanding the needs of clinicians providing care to exposure-concerned Veterans is essential to the HERO Summary’s utility. This abstract presents the design of a survey to assess clinicians’ preferences on the summary format and its representation of military occupational history, exposure characteristics, and health outcomes to support ongoing data aggregation processes. Methods: Clinical needs assessment development involved virtual interviewing clinicians with expertise in military medicine, with questions focusing on summary format, content, and utility. Interview transcripts were qualitatively analyzed to develop a shortened digital survey for broad dissemination to Veteran Affairs (VA) healthcare professionals. Union approval and quality improvement designation were obtained. Results: Feedback from clinician interviews led to enhancements in the readability and accessibility of the survey, regardless of respondents’ exposure literacy levels. The updated clinical needs assessment included questions on the usefulness of MEE data sources, ideal demographic, military-occupational, exposure, and health factors prioritization, incorporation of visual and technical components, and the preferred storage and access of the summaries. To decrease the respondents' burden, the survey length was limited to an average completion duration of about 12 minutes during pilot tests. Data collection among a large pool of VA clinicians with varying specialties and career levels is ongoing, and preliminary analysis has been initiated. Discussion: Existing exposure data repositories do not prioritize clinical utility, ease of understanding, or consistency in interpreting military exposures within clinics across the VA. The present clinical needs assessment avoids such limitations by incorporating clinician feedback in the design and development of the HERO Summary. It intends to increase the adoption of exposure information into clinical care pipelines and thereby facilitate personalized exposure-informed care for Veterans.
