Alcohol Use among Young Women in Kampala City: Comparing Self-Reported Survey Data with Presence of Urinary Ethyl Glucuronide Metabolite

This study sought to determine the level of concordance between self-reported alcohol use and the presence of its urinary ethyl glucuronide (EtG) metabolite in women living in urban Kampala. In 2023, we recruited 300 young women, ages 18 to 24 years, to participate in a prospective cohort study across three sites in urban Kampala (i.e., Banda, Bwaise, and Makindye) to examine the mechanistic pathways of mental illness. As part of the baseline assessment, participants were asked to complete a research assistant-administered survey and to provide a urine sample to screen for 16 different substances and/or their metabolites, including EtG. Overall, 58% (n = 174) reported to have ever consumed alcohol and 23% (n = 68) to have used it in the past month. Among the 300 women, 10% (n = 30) had EtG levels in their urine sample and of these, 40% (n = 12) reported to have never consumed alcohol, using a self-reported survey (p = 0.035). Recent alcohol use was relatively low among the women in this study. However, the discordance between self-reported alcohol use and the presence of EtG presents concerns about the accuracy of self-reported alcohol use. Additional research is needed to contextualize self-reported alcohol use, social desirability, and the implications for alcohol prevention and intervention strategies for young women in urban Kampala.

Prevalence and blood concentrations of benzodiazepines and opioids in opioid-positive death investigations in Ontario, Canada, from 2017 to 2021

The aim of this study was to investigate the incidence of benzodiazepines in opioid-positive death investigations, including trends in frequency and combination of drugs, as well as demographic data and blood concentrations, where available. Additionally, naloxone concentrations in polysubstance compared to opioid-only cases were analyzed. This was a retrospective study that consisted of all post-mortem toxicology cases in Ontario, Canada, from January 01, 2017, to December 31, 2021, with an opioid finding in any analyzed autopsy specimen. There were 11,033 death investigations identified. The overall rate of benzodiazepine co-involvement was 54.5%. Males accounted for the majority of cases (71%), and the most affected age group was 30- to 39-year-olds. The most frequently detected opioid was fentanyl and the most frequently detected benzodiazepine was etizolam, which was also the most frequently observed opioid/benzodiazepine combination. Findings related to differences in concentrations of opioids when naloxone was also present were mostly non-significant, except for methadone. The rate of benzodiazepine detection with opioids grew faster than opioid detections overall, potentially due to the increasingly toxic drug supply. Detection of novel psychoactive drugs fluctuated more unpredictably than opioids and benzodiazepines associated with clinical use. These findings can help inform policy decisions by public health agencies in exploring harm reduction efforts, for example, education and drug-checking services.

BACKGROUND

The patient pathway for follow-up after a drug overdose, which is an important part of Norway's national overdose strategy, started up on 1 January 2022. Four years earlier, a collaboration was initiated between the ambulance service and the drug-related emergency department at Oslo University Hospital with the same aim as this patient pathway: to provide emergency follow-up in the specialist health service after a drug overdose. Uptake of the follow-up provision was minimal, and the purpose of this study was to investigate the reasons behind this.

MATERIAL AND METHOD

We used a case study design and carried out twelve qualitative interviews with representatives from the ambulance service, the drug-related emergency department and the service user group. A thematic analysis of the interviews was then conducted.

RESULTS

The analysis revealed five thematic areas with different explanations for the poor uptake of the service provision. There was insufficient information about the provision, and the admission criteria were unclear. Communication issues between the ambulance service and the drug-related emergency department meant that the provision did not function as an emergency service. The service users' wishes after an overdose did not correspond fully with the provision, and uptake was sometimes associated with sanctions.

INTERPRETATION

The results show that things could have been done differently at a local level, but also that the content of the patient pathway is unclear, and that general guidelines can lead to the provision being perceived as unsafe. The knowledge generated from this survey can help uncover areas that require improvement at a national level in the follow-up pathway after a drug overdose.
