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 are interested in characterizing rates of treatment admissions and death for both adolescents and adults as they require differing treatment strategies and policy responses. We propose a joint spatial conditionally autoregressive model that estimates 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. We will also estimate effects of county-level social environmental covariates to better characterize differences between counties. We will compare the estimates from the joint model to estimates from models that look at each age group separately. We will highlight gains in efficiency and discuss other statistical considerations for taking a joint modeling approach.
