Abstract: Opioid misuse is a national epidemic and a significant public health issue due to its high prevalence of associated morbidity and mortality. Ohio has been hit as hard by the opioid epidemic as any state in the country. We propose a joint spatial factor model to assess the burden of opioids as measured by opioid related treatment admission and death counts. We incorporate spatially varying factor loadings to allow for differential contribution to the spatial factor across space. We also estimate effects of county-level social environmental covariates on the spatial factor to better characterize differences in burden between counties. We also extend this approach to jointly model county-level rates of opioid related treatment admission and death for adolescents and adults. By jointly modeling, we can borrow strength from the adult model to stabilize estimates for adolescents which are based on smaller counts.
