The MilSeq Project

Details and patient eligibility

About

The MilSeq Project is a nonrandomized, prospective pilot study of whole exome sequencing (WES) in the U.S. Air Force. The purpose of this study is to explore the implementation of WES into clinical medical care in the military health system.

Full description

The objective of this effort is to investigate: (a) military healthcare providers' (HCPs') genomic knowledge before and after receiving a genomic educational primer and after disclosing whole exome sequencing (WES) results to begin to assess the genomic educational needs of military HCPs; (b) active-duty Airmen's knowledge and perceptions of genomic sequencing (GS); (c) reasons why active-duty Airmen choose to participate, or not to participate, in research involving GS; (d) how WES study participants, including HCPs and sequenced active-duty Airmen (patient-participants), respond to and use WES results; (e) the collection of medical, behavioral, and healthcare utilization outcomes related to the clinical integration of WES in the military; (f) how return of WES results and integration into the Electronic Medical Record (EMR) do or do not impact perceptions of mission readiness and duty assignments. Given the lack of prior research in this area in the Air Force and the broad number of topics of interest, the aims of the study are predominantly exploratory and results may be hypothesis generating.

The MilSeq Project will be conducted in two sequential phases. Phase I of the study will recruit, consent, and enroll approximately 75 ostensibly healthy active-duty Airmen who receive medical care in military Primary Care, Internal Medicine, and/or Family Practice settings to take a baseline survey. This survey will be administered to explore active-duty Airmen's perceptions of and preferences for GS, identify motivations and barriers to active-duty Airmen participating in a WES study, and assess interest in taking part in the WES study.

Phase II of the study will recruit, consent, and enroll 75 ostensibly healthy active-duty Airmen who receive medical care in military Primary Care, Internal Medicine and/or Family Practice settings who in their baseline survey expressed interest in receiving WES through a research study. WES will be performed on each enrolled patient-participant. The result will be disclosed by an HCP-participant and permanently integrated into the patient-participant's EMR. Phase II will also recruit 10-20 military Primary Care, Internal Medicine, and/or Family Practice HCPs and consent them to participate in the study. The HCPs will receive an educational primer in genomics and will disclose WES results to Airmen participants.

There are a number of potential benefits and challenges to incorporating genomic medicine into the military, some that are relevant to the broader civilian community, but some that are unique to this population. Some of these challenges include: (a) how GS may or may not affect the perception of fitness for duty; (b) how genomic discrimination may or may not occur in the military setting; (c) how to best deal with unanticipated findings; and (d) how genomic results can be practically integrated into a military setting. In this pilot study, these potential opportunities and challenges will be explored, which will provide a basis for future study and begin to inform decisions regarding clinical care of active-duty service members.

105 participants in 2 patient groups

Healthy Active-Duty Airmen Cohort

Experimental group

Description:

Whole exome sequencing (WES) will be performed on 75 ostensibly healthy, active-duty Airmen (patient-participants) who receive medical care in military Primary Care, Internal Medicine and/or Family Practice settings who in their baseline survey expressed interest in receiving WES. Military healthcare providers who have received brief genomics training will return results to the patient-participants and the WES reports will be permanently integrated into their electronic medical record.

Treatment:

Genetic: Whole exome sequencing

Healthcare Provider Cohort

No Intervention group

Description:

The Healthcare providers who provide medical care in military Primary Care, Internal Medicine and/or Family Practice settings and enroll participants. Military healthcare providers have received a brief genomics training and will return results to the patient-participants
