Background and ObjectivesBuprenorphine/naloxone has been shown to be effective in the treatment of opioid use disorder. Due to its pharmacological properties, induction can be challenging, time‐consuming, and result in sudden onset of withdrawal symptoms.MethodsRetrospective case series (n = 2).ResultsTwo patients with opioid use disorder were successfully started on buprenorphine/naloxone using a rapid micro‐induction technique that did not cause precipitated withdrawal or require preceding cessation of other opioids.Discussion and ConclusionsThese cases provide an alternative method for starting buprenorphine/naloxone that offers unique benefits compared to protocols previously described in the literature.Scientific SignificanceThis method can be used to minimize barriers to opioid agonist therapy.

BackgroundIllicit drug injecting is a well-established risk factor for morbidity and mortality. However, a limited number of prospective studies have examined the independent effect of unstable housing on mortality among persons who inject drugs (PWIDs). In this study we sought to identify if a relationship exists between unstable housing and all-cause mortality among PWIDs living in Vancouver, Canada.MethodsPWIDs participating in two prospective cohort studies in Vancouver, Canada were followed between May 1996 and December 2012. Cohort data were linked to the provincial vital statistics database to ascertain mortality rates and causes of death. We used multivariate Cox proportional hazards regression to determine factors associated with all-cause mortality and to investigate the independent relationship between unstable housing and time to all-cause mortality.ResultsDuring the study period, 2453 individuals were followed for a median of 69 months (Inter-quartile range [IQR]: 34 – 113). In total, there were 515 (21.0%) deaths for an incidence density of 3.1 (95% Confidence Interval [CI]: 2.8 – 3.4) deaths per 100 person years. In multivariate analyses, after adjusting for potential confounders including HIV infection and drug use patterns, unstable housing remained independently associated with all-cause mortality (adjusted hazard ratio [AHR] = 1.30, 95% CI: 1.08 – 1.56).ConclusionsThese findings demonstrate that unstable housing is an important risk factor for mortality independent of known risk factors including HIV infection and patterns of drug use. This study highlights the urgent need to provide supportive housing interventions to address elevated levels of preventable mortality among this population.

Background: Due to its unique pharmacologic properties, efficacy as an analgesic, and role as a first-line medication for the treatment of opioid use disorder, sublingual buprenorphine has emerged as a treatment for patients with concurrent chronic pain and opioid use disorders. One challenge to utilizing buprenorphine is that precipitated opioid withdrawal can result if this medication is initiated in the presence of other opiates with lesser binding affinities. Microdosing induction regimens utilize a slower titration to avoid the need for a period of abstinence from other opiates and decrease the risk of precipitated withdrawal. Aims: The aim of this article is to present a case where a standardized micro-dosing induction regimen was used to transition a patient from other opiate analgesia to a sublingual formulation of buprenorphine/naloxone. Methods: This case took place on an inpatient neurosurgical unit of a Canadian tertiary-care city hospital. Written informed consent was collected prior to a detailed chart review. Results: Here we present a case of a postoperative neurosurgical inpatient who was referred to our team for pain management in the context of chronic pain and a past history of opioid use disorder. She was successfully transitioned to buprenorphine/naloxone, replacing all other opioid analgesia, without a period of opioid withdrawal using a micro-dosing induction regimen. Conclusions: Sublingual buprenorphine/naloxone can be safe and effective for treatment of chronic pain, particularly for those with past or current opioid use disorder. Micro-dosing provides a preferable induction strategy for patients who are not able to tolerate the requirement for moderate opioid withdrawal prior to initiation with existing regimens. RÉSUMÉ

Loss of housing and income assistance among vulnerable youth has not been well described in the literature, yet it is a crucial issue for public health. This study examines the prevalence and correlates of loss of income assistance as well as eviction among street-involved youth. We collected data from a prospective cohort of street-involved youth aged 14–26. Among 770 participants, 64.3% reported having housing and 77.1% reported receiving income assistance at some point during the study period. Further, 28.6% and 20.0% of youth reported having been evicted and losing income assistance, respectively. In multivariable generalized estimating equations (GEE) analysis, heavy alcohol use, unprotected sex, being a victim of violence, and homelessness were all independently associated with eviction. Separately, homelessness, recent incarceration, and drug dealing were independently associated with loss of income assistance. Eviction and loss of income assistance are common experiences among street-involved youth with multiple vulnerabilities. Our findings highlight the importance of improving continued engagement with critical social services.
