Suicide in people prescribed opioid-agonist therapy in Scotland, United Kingdom, 2011–2020: A national retrospective cohort study 🔓

Addiction

This retrospective cohort study aimed to determine if opioid agonist therapy (OAT) in Scotland is protective against suicide, and measure trends in suicide rates in those with opioid dependence over time. The study included 46,453 individuals who received at least one prescription for OAT between 2011 and 2020 with over 304,000 person-years (pys) of follow-up. Results suggested that people with opioid dependence in Scotland have a greater risk of suicide than the general population. Treatment is protective, with rates of suicide lower among those on opioid agonist therapy. Suicide rates have decreased over time, during a period in which drug-related death rates in Scotland have risen to globally high levels.

Links between adolescent binge drinking and midlife alcohol use behaviors by age, sex, and race/ethnicity 🔓

Alcohol Clinical and Experimental Research

Using data from the Monitoring the Future study, which enrolled cohorts of high school seniors annually starting in 1976, this analysis evaluated alcohol drinking patterns in adults 35-60 and potential association with their drinking patterns at age 18. Overall, the reported mean number of drinks at a time ranged from 1.7 to 1.4, and the mean maximum number of drinks ranged from 3.2 to 2.3. The reported number of drinks was generally lower at older ages. Those who reported binge drinking at 18 versus those who did not report a significantly higher mean (2.3 vs. 1.3) and maximum (4.0 vs. 2.3) number of drinks as adults. Additionally, they were more likely to report binge drinking (39.5% vs 19.1%) and high-intensity drinking (10.5% vs 4.4%) as adults. Further, this association was even stronger in older age groups, suggesting adolescent binge drinking is a risk factor across the lifespan.

Buprenorphine/Naloxone vs Methadone for the Treatment of Opioid Use Disorder

JAMA Network

This population-based retrospective cohort study assessed whether the use of buprenorphine/naloxone is associated with lower risk of treatment discontinuation and mortality compared with methadone. It included 30,891 individuals initiating treatment for the first time during the study period and found that the risk of treatment discontinuation was higher among recipients of buprenorphine/naloxone compared with methadone (88.8% vs 81.5% within 24 months). The risk of mortality was low while in either form of treatment (0.08% vs 0.13%). Individuals receiving methadone had a lower risk of treatment discontinuation compared with those who received buprenorphine/naloxone. The risk of mortality while receiving treatment was similar between medications.
