All local health departments struggle with the question of how best to enhance public health preparedness with limited time and resources. The article by Paige et al. describes a local initiative that yielded improved awareness and readiness for some aspects of emergency response, and a realistic assessment of increased uncertainty for other, more complex and policy-level aspects. Paige and colleagues are to be commended for carefully evaluating the impacts of mounting a wide-scale, staged exercise to assess readiness to implement the local Pandemic Influenza Response Plan. Participants were observed to gain quick familiarity with the operational, logistical aspects of response, but they also learned how decision-making rapidly involves substantial and complex policy issues that range across jurisdictions. Direct observation of preparedness processes in large drills is an increasingly effective tool for public health preparedness.
