OBJECTIVE:: To assess missed opportunities for reducing fatal opioid overdoses, characteristics of decedents by opioid overdose with and without problematic opioid use who received health care services within one year of death were examined.

METHODS:: Of 157 decedents in the Worcester, Massachusetts, area between 2008 and 2012, 112 had contact with the health care system. Electronic medical records were reviewed for clinical characteristics, health service use, universal precautions, and substance use disorder management. Problematic opioid use was defined as individuals having documented opioid use disorders or aberrant drug-related behavior. Data were analyzed with chi-square tests with adjusted residual for categorical variables and t tests for continuous variables.

RESULTS:: Decedents were predominantly Caucasian males with a mean+/-SD age of 41.0+/-11.7. Problematic opioid use by definition meant users (N=53) had opioid use disorder as a principal diagnosis and were likely to have a comorbid substance use disorder. Decedents with nonproblematic opioid use had diagnoses of chronic pain and mental illness. They were more likely to have been seen last in surgical and subspecialty settings (29% versus 11%). The proportion with an opioid prescription was higher among those with problematic use (72% versus 37%) who also had a higher total daily morphine equivalent, compared with those with nonproblematic use (165.4+/-282.7 versus 55.6+/-117.7 mg per day).

CONCLUSIONS:: Persons with problematic opioid use are a recognizable group with a high risk of death by opioid overdose whose therapeutic management needs improvement to reduce fatal outcomes. Different strategies must be developed for identifying and treating nonproblematic opioid use to reduce risk of death.
