Tornado diagram from one-way sensitivity analyses of the economic impact of untreated MMHCs among 2019 births: All Texas mothers. SOURCE: Authors’ analysis. NOTES: MMHCs = maternal mental health conditions; SIDS = sudden infant death syndrome. The tornado diagram above shows the results of our sensitivity analyses, including the difference in costs, in millions of dollars, from the main model as we varied each parameter from its lowest to its highest value. The impact estimate of exposure to MMHCs on productivity losses had the greatest impact on estimated costs ($1.7 billion to $2.7 billion), followed by the remission rate ($1.9 billion to $2.8 billion) and preterm birth ($1.8 billion to $2.3 billion). These parameters had large ranges in the literature and the costs of these outcomes were very high, so varying these parameters led to substantial variation in model results. Other impact parameters had a more modest impact on model results because the baseline rate of the outcome was low, the costs incurred through five years post-delivery were low or the range of impact estimates was small. By varying all parameters at once, we found that total societal cost of untreated MMHCs in Texas could range from $739 million to $4.3 billion for the 2019 birth cohort
