Abstract
Aims
To measure all-cause mortality risk after an ambulance-attended non-fatal opioid overdose and associations with number of days following attendance, and individual and clinical characteristics.
Design
A prospective observational study.
Setting
Oslo, Norway.
Participants
Patients treated with naloxone for opioid overdose by Oslo Emergency Services between 1 June 2014 and 31 December 2018.
Measurements
Medical records were linked to the national Cause of Death Registry (1 June 2014–31 December 2019). Crude mortality rates (CMR) and incidence risk ratios (IRR) with 95% confidence intervals (CI) were estimated for the time periods (0–7 days, 8–31 days, 32–91 days, 92–183 days, >183 days) using multivariate Poisson regression analysis. IRR were estimated for sex, age, Glasgow Coma Scale (GCS), respiration rate, place of attendance and non-transportation following treatment. Robust variance estimates applied due to multiple risk periods. Standardized Mortality Rates (SMR) were estimated.
Findings
Overall, 890 patients treated for 1764 overdoses contributed to a total time at risk of 3142 person-years (PY). Median number of attendances was 1 (range 1–27). The majority were male (75.5%) and the mean age was 37.7 years. In total, 112 (12.6%) died; 5.2% within 183 days and 2.2% between 184 and 365 days. Acute poisoning was the most common single cause of death (52.7%). The CMR was 3.6 (95% CI = 3.0–4.2) per 100-PY. The women had a SMR of 32 (95% CI = 15.8–57.9) and the men 24.9 (95% CI = 17.7–34.2). The CMR (22.2, 95% CI = 10.6–46.8) was particularly high in the first 7 days, and significantly higher than in the following periods. However, this finding was only valid for those with severe overdose symptoms (GCS score = 3/15 and/or respiratory rate ≤6/min). Except for increasing age, no other indicators were associated with the mortality risk.
Conclusion
Patients treated by Oslo Emergency Services between June 2014 and December 2018 for a non-fatal opioid overdose with severe overdose symptoms at attendance had an overall high mortality risk compared with the general population, but particularly during the first 7 days after attendance.
期刊介绍:
Addiction publishes peer-reviewed research reports on pharmacological and behavioural addictions, bringing together research conducted within many different disciplines.
Its goal is to serve international and interdisciplinary scientific and clinical communication, to strengthen links between science and policy, and to stimulate and enhance the quality of debate. We seek submissions that are not only technically competent but are also original and contain information or ideas of fresh interest to our international readership. We seek to serve low- and middle-income (LAMI) countries as well as more economically developed countries.
Addiction’s scope spans human experimental, epidemiological, social science, historical, clinical and policy research relating to addiction, primarily but not exclusively in the areas of psychoactive substance use and/or gambling. In addition to original research, the journal features editorials, commentaries, reviews, letters, and book reviews.
