ABSTRACT
As behavioural health occupations have diversified, more specialists such as social workers and counsellors are involved in providing substance use disorder treatment services. This study examined the association between changes in the number of different types of behavioural health professionals and changes in drug and opioid overdose deaths in the United States. Using publicly available state-level data from 2008 to 2017, we constructed multivariate linear regression models with state- and year fixed-effects to examine the effect of changes in the number of different types of behavioural health professionals (i.e. psychiatrists, psychologists, social workers and counsellors) on changes in drug and opioid overdose deaths at the state level, controlling for state population characteristics and other state-level factors. After controlling for confounding factors, a 1% increase in the number of social workers and counsellors at the state level was significantly associated with a 0.215% reduction in drug overdose deaths per 100,000 state population and with a 0.358% reduction in opioid overdose deaths per 100,000 state population. We did not find statistically significant associations between changes in drug overdose death rates and increases in the number of psychiatrists or psychologists alone. Our findings suggest efforts to facilitate a prepared and skilled workforce, such as expanding the capacity of social workers and counsellors, to maximise access to substance use disorder treatment services.
