Many patients are treated in the emergency room for non-fatal opioid overdose. However, it is unknown what proportion of these patient population experience subsequent fatality after their ED visit.
A recent study investigated the 1-year mortality rate among Massachusetts ED patients who were treated and discharged from ED for non-fatal opioid overdose.
Results
11,557 patients were identified between July 1, 2011 and September 30, 2015.
There were 635 fatalities (5.5%) within 1 year in this cohort.
Of these, 428 (67.4%) died due to opioid overdose
Of those who died,
130 (20.5%) died within 1 month
29 (4.6%) died within 2 days.
Manner of death
Natural causes: 121 (19.1%)
Accidental: 460 (72.4%)
Suicide: 13 (2.0%)
Other/pending investigation: 41 (6.5%)
Place of death
Hospital: 310 (48.8%)
Residence: 146 (23.0%)
Other/unknown/nursing home: 179 (28.2%)
Conclusion
There is high rate of fatality within 1 month (20.5%) after non-fatal opioid overdose ED visits.
Subsequent fatal opioid overdose was observed in 428 (67.4%) of the cohort.
