Aims To compare morbidity and mortality in opioid dependence patients following the commencement of treatment with the general population. Methods Morbidity and mortality in all patients treated with methadone, buprenorphine or implant naltrexone for opioid dependence for the first time between 2001 and 2010 in Western Australia was compared to a cohort of age and gender matched controls using state health records. Results Compared to community controls rates of all-cause mortality, hospital admissions and Emergency Department attendances are significantly elevated in opioid dependent persons following the commencement of their first treatment. Not surprisingly, rates of opioid and non-opioid drug poisoning, and intentional self-harm/suicide mortality and hospital admissions were significantly elevated in opioid dependent patients compared with non-dependent controls. However, significant increases in mortality and hospital admissions for conditions which are not generally associated with opioid use were also identified including cardiovascular, respiratory and traffic accidents. Life-time prevalence of both HBV and HCV were significantly elevated in opioid dependent patients compared with non-dependent patients. Conclusions Even after the commencement of treatment, opioid dependent patients are at a high risk of morbidity and mortality compared with non-dependent age and gender matched controls.
