Panel 2: anticipatory risk assessment: identifying, assessing, and mitigating exposure risks before they occur

Health threats place the military mission and deployed service members at risk. A commander's focus is on preventing acute health risks, such as diarrhea, because these quickly compromise the mission. However, in recent conflicts chronic and long-term illness risks have emerged as concerns. Department of Defense and Joint Chiefs of Staff mandates require documentation of exposures and environmental conditions to reconstruct exposures and evaluate future health risks. Current processes for identifying and assessing hazards, including identification and assessment before deployment and in time to take action to prevent or reduce exposures, when followed, are generally adequate for known hazards. Identifying and addressing novel, unexpected risks remain challenges. Armed conflicts are associated with rapidly changing conditions, making ongoing hazard identification and assessment difficult. Therefore, surveillance of the environment for hazards and surveillance of personnel for morbidity must be practiced at all times. Communication of risk information to decision makers is critical but problematic. Preventive Medicine (PM) personnel should take responsibility for communicating this information to non-PM military medical people and to military commanders. Communication of risks identified and lessons learned between PM personnel of different military units is extremely important when one military unit replaces another in a deployed environment.
