In preparing for influenza pandemics, public health agencies stockpile critical
medical resources. Determining appropriate quantities and locations for such
resources can be challenging, given the considerable uncertainty in the timing
and severity of future pandemics. We introduce a method for optimizing stockpiles
of mechanical ventilators, which are critical for treating hospitalized influenza
patients in respiratory failure. As a case study, we consider the US state of
Texas during mild, moderate, and severe pandemics. Optimal allocations prioritize
local over central storage, even though the latter can be deployed adaptively, on
the basis of real-time needs. This prioritization stems from high geographic
correlations and the slightly lower treatment success assumed for centrally
stockpiled ventilators. We developed our model and analysis in collaboration with
academic researchers and a state public health agency and incorporated it into a
Web-based decision-support tool for pandemic preparedness and response.
