Introduction: Take-Home Naloxone programs have been introduced across North America in response to rising opioid overdose deaths. There is currently limited real-world data on bystander naloxone administration, overdose outcomes, and evidence related to adverse events following bystander naloxone administration. Methods: The research team used descriptive statistics from Take-Home Naloxone administration forms. We explored reported demographic variables and adverse events among people who received by-stander administered naloxone in a suspected opioid overdose event between August 31, 2012 and December 31, 2018 in British Columbia. We examined and contextualized differences across years given policy, program and drug toxicity changes. We used multivariate logistic regression to examine whether an association exists between number of ampoules of naloxone administered and the odds that the recipient will experience withdrawal symptoms. Results: A large majority (98.1%) of individuals who were administered naloxone survived their overdose and 69.2% had no or only mild withdrawal symptoms. Receiving three (Adjusted Odds Ratio (AOR) 1.64 (95% Confidence Interval (CI): 1.08–2.48)) or four or more (AOR 2.19 (95% CI: 1.32–3.62)) ampoules of naloxone was significantly associated with odds of moderate or severe withdrawal compared to receiving one ampoule of naloxone. Conclusions: This study provides evidence from thousands of bystander reversed opioid overdoses using Take-Home Naloxone kits in British Columbia, and suggests bystander-administered naloxone is safe and effective for opioid overdose reversal. Data suggests an emphasis on titration during bystander naloxone training in situations where the person experiencing overdose can be adequately ventilated may help avoid severe withdrawal symptoms. We identified a decreasing trend in the likelihood of moderate or severe withdrawal over the study period. [ABSTRACT FROM AUTHOR]

Introduction: The BC Centre for Disease Control implemented the Facility Overdose Response Box (FORB) program December 1st, 2016 to train and support non-healthcare service providers who may respond to an overdose in the workplace. The program aims to support staff at non-profit community-based organizations by ensuring policy development, training, practice overdose response exercises, and post-overdose debriefing opportunities are established and implemented. Materials and methods: Three data sources were used in this descriptive cross-sectional study: FORB site registration data; naloxone administration forms; and a survey that was distributed to FORB sites in February 2019. FORB program site and naloxone administration data from December 1st, 2016 to December 31st, 2019 were analyzed using descriptive statistics. A Cochran-Armitage test was used to assess trends over time in naloxone administration event characteristics. Site coordinator survey results are reported to supplement findings from administrative data. Results: As of December 31st, 2019, FORB was implemented at 613 sites across BC and 1,758 naloxone administration events were reported. The majority (86.3%, n = 1,517) were indicated as overdose reversals. At registration, 43.6% of sites provided housing services, 26.3% offered harm reduction supplies, and 18.6% provided Take Home Naloxone. Refusal to be transported to hospital following overdose events when emergency services were called showed an increasing trend over time. Most respondents (81.3%) reported feeling confident in their ability to respond to the overdose and 59.6% were offered staff debrief. Based on the 89 site survey responses, supports most commonly made available following an overdose were debrief with a fellow staff member (91.0%), debrief with a supervisor (89.9%), and/or counselling services (84.3%). Conclusions: The uptake of the FORB program has contributed to hundreds of overdose reversals in community settings in BC. Findings suggest that the FORB program supports developing staff preparedness and confidence in overdose response in community-based settings. [ABSTRACT FROM AUTHOR]

Introduction: British Columbia's (BC) Take-Home Naloxone (THN) program provides naloxone to bystanders for use in cases of suspected opioid overdose. This study seeks to provide trends and analysis from the provincial BC THN program since inception in 2012 to the end of 2018. Materials and methods: BC THN shipment and distribution records from 2012–2018 were retrieved. Frequency distributions were used to describe characteristics of individuals accessing the program. To evaluate correlates of distribution after the addition of hundreds of pharmacy distribution sites, an analytic sample was limited to records from 2018, and multivariate logistic regression was used to evaluate correlates of collecting naloxone at a pharmacy site. Results: Since program inception to the end of 2018, there were 398,167 naloxone kits shipped to distribution sites, 149,999 kits reported distributed, and 40,903 kits reported used to reverse an overdose in BC. There was a significant increasing trend in the number of naloxone kits used to reverse an overdose over time (p<0.01), and more than 90% of kits that were reported used were distributed to persons at risk of an overdose. Individuals not personally at risk of overdose had higher odds of collecting naloxone at a pharmacy site, compared to other community sites (including harm reduction supply distribution sites, peer led organizations, drop-in centers, and supportive housing sites) (Adjusted Odds Ratio (AOR): 2.69; 95% CI: 2.50–2.90). Conclusions: This study documents thousands of opioid overdose reversals facilitated through the BC THN program. While those at highest risk of overdose may preferentially access naloxone through community sites, naloxone distribution through pharmacies has allowed the BC THN program to expand dramatically, increasing naloxone availability through longer opening hours on evenings and weekends. and in rural and remote regions. A diversity of naloxone distribution sites and strategies is crucial to prevent rising opioid overdose deaths. [ABSTRACT FROM AUTHOR]
