RESUMEN
AIMS: This study aimed to evaluate whether voluntary and mandatory prescription drug monitoring program (PDMP) use in Victoria, Australia, had an impact on prescribing behaviour, focusing on individual patients' prescribed opioid doses and transition to prescribing of nonmonitored medications. METHODS: This was a retrospective cross-sectional study using routinely collected primary healthcare data. A 90-day moving average prescribed opioid dose in oral morphine equivalents was used to estimate opioid dosage. A Markov transition matrix was used to describe how patients prescribed medications transitioned between opioid dose groups and other nonopioid treatment options during 3 transition periods: transition between 2 control periods prior to PDMP implementation (T1 to T2); during the voluntary PDMP implementation (T2 to T3); and during mandatory PDMP implementation (T3 to T4). RESULTS: Among patients prescribed opioids in our study, we noted an increased probability of transitioning to not being prescribed opioids during the mandatory PDMP period (T3 to T4). This increase was attributed mainly to the ceasing of low-dose opioid prescribing. Membership in an opioid dose group remained relatively stable for most patients who were prescribed high opioid doses. For those who were only prescribed nonmonitored medications initially, the probability of being prescribed opioids increased during the mandatory PDMP when compared to other transition periods. CONCLUSION: The introduction of PDMP mandates appeared to have an impact on the prescribing for patients who were prescribed low-dose opioids, while its impact on individuals prescribed higher opioid doses was comparatively limited.

OBJECTIVE: To identify common opioid tapering trajectories among patients commencing opioid taper from long-term opioid therapy for chronic non-cancer pain and to examine patient-level characteristics associated with these different trajectories. DESIGN: A retrospective cohort study. SETTING: Australian primary care. SUBJECTS: Patients prescribed opioid analgesics between 2015 and 2020. METHODS: Group-based trajectory modeling and multinomial logistic regression analysis were conducted to determine tapering trajectories and to examine demographic and clinical factors associated with the different trajectories. RESULTS: A total of 3369 patients commenced a taper from long-term opioid therapy. Six distinct opioid tapering trajectories were identified: low dose / completed taper (12.9%), medium dose / faster taper (12.2%), medium dose / gradual taper (6.5%), low dose / noncompleted taper (21.3%), medium dose / noncompleted taper (30.4%), and high dose / noncompleted taper (16.7%). A completed tapering trajectory from a high opioid dose was not identified. Among patients prescribed medium opioid doses, those who completed their taper were more likely to have higher geographically derived socioeconomic status (relative risk ratio [RRR], 1.067; 95% confidence interval [CI], 1.001-1.137) and less likely to have sleep disorders (RRR, 0.661; 95% CI, 0.463-0.945) than were those who didn't complete their taper. Patients who didn't complete their taper were more likely to be prescribed strong opioids (eg, morphine, oxycodone), regardless of whether they were tapered from low (RRR, 1.444; 95% CI, 1.138-1.831) or high (RRR, 1.344; 95% CI, 1.027-1.760) doses. CONCLUSIONS: Those prescribed strong opioids and high doses appear to be less likely to complete tapering. Further studies are needed to evaluate the clinical outcomes associated with the identified trajectories.

OBJECTIVE: To examine the predictors of persistent opioid use ('persistence') in people initiating opioids for non-cancer pain in Australian primary care. DESIGN: A retrospective cohort study. SETTING: Australian primary care. SUBJECTS: People prescribed opioid analgesics between 2018-2022, identified through the Population Level Analysis and Reporting (POLAR) database. METHODS: Persistence was defined as receiving opioid prescriptions for at least 90 days with a gap of less than 60 days between subsequent prescriptions. Multivariable logistic regression was used to examine the predictors of persistent opioid use. RESULTS: The sample consisted of 343,023 people initiating opioids for non-cancer pain; of these, 16,527 (4.8%) developed persistent opioid use. Predictors of persistence included older age (≥75 vs 15-44 years: Adjusted odds ratio: 1.67, 95% CI: 1.58-1.78), concessional beneficiary status (1.78, 1.71-1.86), diagnosis of substance use disorder (1.44, 1.22-1.71) and chronic pain (2.05, 1.85-2.27), initiation of opioid therapy with buprenorphine (1.95, 1.73-2.20) and long-acting opioids (2.07, 1.90-2.25), provision of higher quantity of opioids prescribed at initiation (total OME of ≥ 750mg vs < 100mg: 7.75, 6.89-8.72), provision of repeat/refill opioid prescriptions at initiation (2.94, 2.77-3.12), and prescription of gabapentinoids (1.59, 1.50-1.68), benzodiazepines (1.43, 1.38-1.50) and z-drugs (e.g., zopiclone, zolpidem; 1.61, 1.46-1.78). CONCLUSIONS: These findings add to the limited evidence of individual-level factors associated with persistent opioid use. Further research is needed to understand the clinical outcomes of persistent opioid use in people with these risk factors to support the safe and effective prescribing of opioids.
RESUMEN
BACKGROUND AND AIMS: The Medical Priority Dispatch System (MPDS)® is used to triage 9-1-1 calls according to acuity, with certain coding receiving telecommunicator cardiopulmonary resuscitation (T-CPR) for suspected out-of-hospital cardiac arrest (OHCA). However, this may be challenging for those with drug poisoning emergencies, who may resemble OHCA. We sought to examine the performance of the system to correctly identify cases requiring T-CPR, specifically at overdose prevention services (OPS). METHODS: This retrospective cohort study included patients attended by the provincial emergency medical system (EMS) (May 1, 2019-January 31, 2023). We calculated the diagnostic performance of MPDS® assessment of whether the case required T-CPR instructions against the gold standard of whether the patient was found pulseless on EMS clinician arrival. We compared performance among subgroups, specifically OPS vs other locations and drug poisoning-classified cases vs other case classifications. RESULTS: Comparing OPS to other locations, the sensitivity of MPDS® was similar (66.7% vs 62.4%, p = 0.4), with lower specificity (87.3% vs 98.1%, p < 0.01) and positive predictive value (0.3% vs 35.7%, p < 0.01) and higher negative predictive value (99.9% vs 99.4%, p < 0.01). The negative likelihood ratio of MPDS® was 0.381 at OPS locations, compared with 0.383 at other locations, while the positive likelihood ratio was 5.24, compared with 32.36. In patients with drug poisoning emergencies, compared with other 9-1-1 events, MPDS® had higher sensitivity (83.6% vs 60.6%, p < 0.01) but lower specificity (77.6% vs 98.9%, p < 0.01) and positive predictive value (10.5% vs 48.5%, p < 0.01), and similar negative predictive value (99.33% vs 99.35%, p = 0.03). The negative likelihood ratio of MPDS® was 0.212 in drug poisoning emergencies compared with 0.398 for all other presentations, and the positive likelihood ratio was 3.73 compared with 57.88. DISCUSSION AND CONCLUSIONS: The ability of MPDS® to correctly identify patients needing telecommunicator cardiopulmonary resuscitation instructions differed between OPS settings and other locations, frequently recommending T-CPR for patients not suffering OHCA at an OPS. Different strategies developed in collaboration with people who use substances are required to better tailor dispatch instructions prior to EMS arrival to avoid delays in life-saving interventions.
RESUMEN
BACKGROUND: Effective alcohol and other drugs (AODs) treatment has been proven to increase productivity and reduce costs to the community. Telehealth has previously been proven effective at delivering AOD treatment in the right settings. Yet, Australia's current Medicare funding restricts telephone consultations. AIM: We hypothesise that treatment modality influences attendance rates. Specifically, telephone consultations can remove barriers to accessing treatment and, therefore, can increase attendance. METHODS: We conducted a retrospective audit on our addiction medicine specialist outpatient service from 1 July 2022 to 30 June 2023. A mixed-effects logistic regression model was used to analyse factors associated with attendance rates. RESULTS: There were 576 participants in the study, and 3354 appointments were booked over the 12-month study period. Of these, 2695 were face-to-face, 541 were telephone and 118 were video. The unadjusted raw attendance rate was highest in the telephone group (87.24%), followed by face-to-face (73.02%) and video (44.92%). After adjusting for covariates, telephone consultation was associated with significantly increased odds of attending compared to face-to-face (odds ratio (OR) = 2.60, 95% confidence interval (CI) = 1.90-3.54, P < 0.001). Video consultation was associated with a 69% reduction in the odds of attending compared to face-to-face (OR = 0.31, 95% CI = 0.019-0.49, P < 0.001). CONCLUSIONS: While physical attendance may be required for specific clinical care, telephone consultations are associated with increased attendance and can form an important adjunct to delivering addiction treatment. Given the substantial costs of substance use disorders, this could inform government policies and funding priorities to further improve access and treatment outcomes.
RESUMEN
PURPOSE OF REVIEW: Collaborative models of care where pharmacists work alongside physicians have been developed for a range of physical health conditions, with benefits including improved patient outcomes and increased access to ongoing care. Opioid agonist treatment (methadone and buprenorphine) is a clinically effective and cost-effective treatment for opioid use disorder that is under-utilized in many countries due to a shortage of prescribers. In recent years, there has been increased interest in the development of collaborative models that utilize pharmacists to overcome barriers to treatment. In this article, we present a narrative review to synthesise recent work in this rapidly developing area. RECENT FINDINGS: Two key aspects of opioid agonist treatment were identified: Collaborative models have utilized pharmacists to facilitate buprenorphine induction, and collaborative models provide increased capacity for delivering ongoing care in a variety of settings and patient groups where prescriber access is limited. Pharmacists have undertaken direct patient care responsibilities with varying degrees of autonomy, with benefits including a reduction in prescriber workload, and improvements in treatment retention and continuity of care. SUMMARY: Collaborative models in which pharmacists are responsible for buprenorphine induction and ongoing management with methadone and buprenorphine have been shown to reduce demands on prescribers while improving or maintaining patient outcomes, and appear feasible and acceptable in a wide range of outpatient settings.

INTRODUCTION: Naloxone is an opioid receptor antagonist, which can rapidly reverse the effects of an opioid overdose. Community pharmacists may experience several barriers to stocking and supplying naloxone including a lack of confidence or knowledge and time constraints. The current study aimed to examine the extent to which Victorian community pharmacies stock and supply naloxone and determine specific characteristics associated with stocking naloxone. METHODS: A representative sample of community pharmacists (n = 558) in Victoria, Australia, were contacted between October and November 2020 and invited to participate in an online survey. Data related to pharmacy- and pharmacist-related characteristics, including stocking and frequency of supplying naloxone in the past year. Multivariate logistic regression analysis was performed to examine the effect of various covariates on stocking naloxone. RESULTS: The sample comprised 265 pharmacists (response rate 47%). Most pharmacies were located in Melbourne (the capital city of Victoria, 59.6%) and were part of a pharmacy chain (61.5%). In total, 100 (38%) pharmacies stocked naloxone, a third of whom did not supply it in the past year. Pharmacies that provided opioid agonist treatment had 2.4 times higher odds of stocking naloxone (95% confidence interval 1.425-4.136; p = 0.001). DISCUSSION AND CONCLUSION: Less than half of Victorian community pharmacies stock naloxone, with even fewer actually supplying it in the past year. Future efforts are needed to increase the number of pharmacies that stock naloxone and the frequency in which it is supplied, while also addressing possible barriers to stocking and supplying naloxone among community pharmacists.

BACKGROUND: Codeine was rescheduled in Australia to prescription only in February 2018. Initial studies reported an increase in population level paracetamol and ibuprofen sales following codeine upscheduling. However, to date no study has been able to investigate changes in non-opioid analgesic use at the individual patient level to determine if sales data reflect actual consumption patterns. AIM: To address this gap, we aimed to determine the impact of codeine rescheduling on non-opioid analgesic use in people who regularly used over-the-counter codeine, primarily for pain, prior to the rescheduling change. METHOD: We conducted a prospective cohort study with 260 participants who reported regular over-the-counter codeine consumption at cohort entry. Surveys were completed at baseline (November 2017, 3 months before rescheduling) and at 1 month (February 2018), 4 months (June 2018), and 12 months (February 2019), following rescheduling. The primary outcomes were mean daily doses of non-opioid analgesics, captured through a 7 day medication diary. RESULTS: The mean daily paracetamol dose decreased from 1754.4 mg (95% CI 1300.5-2208.3) at baseline to 1023.8 mg (95% CI 808.5-1239.1) at the final time-point (+ 12 months) (p = .009). The mean daily ibuprofen dose decreased from 305.1mg (95% CI 217.9-392.4) at baseline to 161.2 mg (95% CI 98.5-224.0) 12 months after rescheduling (p = .03). No significant change in doses of other medications remained was found. CONCLUSION: In people who regularly consumed over-the-counter codeine, doses of non-opioid analgesics either reduced or remained stable following codeine rescheduling, suggesting concerns of medication substitution or overuse following the change were not realised.
RESUMEN
BACKGROUND: Opioid use prior to spinal surgery is common among patients with workers' compensation (WC) claims. Extended opioid use for pain management in this population is associated with several adverse outcomes including delayed return to work (RTW). OBJECTIVE: This systematic review and meta-analysis aim to assess the evidence on the association of preoperative opioid use with stable RTW and RTW within 1-year after spinal surgery. MATERIAL AND METHODS: The authors searched MEDLINE, Embase, PsycINFO, Emcare, CINAHL Plus, Scopus, and Web of Science from inception to 14 January 2023. The authors included studies that compared any preoperative opioid use with no opioid use, and those that enabled a comparison of different durations of preoperative opioid use. The primary outcome was stable RTW after spinal surgery. Secondary outcomes were RTW within 1-year after surgery and cost of WC claims. A random effect model was assumed to pool the effect estimate. The GRADE approach was applied to evaluate the certainty of evidence. RESULTS: From 2589 records, 10 studies were included, and of these, nine were considered for quantitative synthesis. All studies were observational with eight retrospective cohort and two case-control studies. Five studies each investigated cervical and lumbar disorders. With moderate certainty evidence, the odds of postoperative stable RTW reduced by half (OR: 0.51, 95% CI: 0.43-0.59; 5549 participants) in patients using opioids preoperatively. Similarly, moderate certainty evidence from 2348 participants demonstrated that the odds of RTW within 1-year after surgery were reduced by more than half in patients with preoperative opioid prescriptions (OR: 0.46, 95% CI: 0.36-0.59). CONCLUSIONS: This systematic review and meta-analysis shows that preoperative opioid use is associated with a reduction in odds of postoperative RTW by half in patients with WC-funded spinal surgery.

INTRODUCTION: Opioid-related overdose fatalities are rising despite the increased accessibility of take-home naloxone (THN). Targeted implementation strategies are needed to improve the distribution of naloxone. This study investigates the effectiveness of a short video targeting pharmacists that addresses implementation barriers. METHODS: A pre-post, mixed methods design was adopted to examine the effect of a brief behaviour change intervention (an educational video informed by the capability, opportunity, motivation affecting behaviour (COM-B) model), on factors affecting pharmacists' implementation of THN in Western Australia. Paired samples t-tests for were used to investigate intentions, knowledge, skill, confidence, feasibility, appropriateness, acceptability, attitudes, anticipated patient reactions, social support and implementation climate. Structural equation modelling examined the associations between constructs and to test the proposed mediation of motivation on capability and opportunity affecting intentions to discuss and provide THN. RESULTS: We analysed data from 102 participants. At follow-up and after all participants had viewed the video, participants had significantly improved intentions, skill, confidence, anticipated reactions, social support and perceptions that THN implementation was feasible, appropriate and acceptable. No significant differences were seen for attitudes, knowledge or implementation climate. The proposed mediation effect of motivation on the associations between opportunity and intentions and capability and intentions was not supported. DISCUSSION AND CONCLUSIONS: A short video directly targeting identified implementation barriers has the ability to improve key influences in the provision of THN. Dissemination of information to community pharmacists is a challenge. Implementation strategies addressing knowledge and targeting other levels of influence on intentions and behaviour are required.

ABSTRACT: Current research indicates that tapering opioids may improve pain and function in patients with chronic noncancer pain. However, gaps in the literature remain regarding the choice of opioid and nonopioid interventions to support a successful taper. This study used an Australian primary care data set to identify a cohort of patients on long-term opioid therapy commencing opioid taper between January 2016 and September 2019. Using logistic regression analysis, we compared key clinical factors associated with differing taper outcomes. Of a total of 3371 patients who commenced taper, 1068 (31.7%) completed taper within 12 months. In the 3 months after commencement of taper, compared with those who did not complete taper, patients who successfully completed opioid taper were less likely to be prescribed buprenorphine (odds ratio [OR] 0.691; 95% CI: 0.530-0.901), fentanyl (OR, 0.429; 95% CI: 0.295-0.622), and long-acting (LA) opioids, including methadone (OR, 0.349; 95% CI: 0.157-0.774), oxycodone-naloxone (OR, 0.521; 95% CI: 0.407-0.669), and LA tapentadol (OR, 0.645; 95% CI: 0.461-0.902), but more likely to be prescribed codeine (OR, 1.308; 95% CI: 1.036-1.652). Compared with those who did not complete taper, patients who successfully tapered were less likely to be prescribed any formulations of oxycodone (short-acting [SA]: OR, 0.533; 95% CI: 0.422-0.672, LA: OR, 0.356; 95% CI: 0.240-0.530) and tramadol (SA: OR, 0.370; 95% CI: 0.218-0.628, LA: OR, 0.317; 95% CI: 0.234-0.428). The type of opioid prescribed in the months after commencement of taper seems to influence the taper outcomes. These findings may inform prospective studies on opioid taper.

BACKGROUND: Provision of take-home naloxone (THN) and overdose education reduces opioid-related mortality. In Australia, from July 2022, all Australian community pharmacies were eligible to supply naloxone for free through the national THN Program. AIM: This study aimed to identify naloxone stocking rates and correlates of stocking naloxone across Australian pharmacies. METHOD: Data were collected from a representative sample of Australian pharmacists in Victoria, New South Wales, Queensland and Western Australia via an online survey. Data collected included pharmacy and pharmacist characteristics and services offered within the pharmacy, including needle and syringe programs, opioid agonist treatment (OAT) and stocking naloxone. Binary probit regression analysis was used to identify correlates of stocking naloxone after controlling for key covariates. RESULTS: Data from 530 pharmacists were analysed. In total, 321 pharmacies (60.6%) reported stocking naloxone. Chain pharmacies and pharmacies that provided OAT had a greater probability of stocking naloxone (B = 0.307, 95%CI: [0.057, 0.556], and B = 0.543, 95%CI: [0.308, 0.777] respectively). Most (61.7%) pharmacists felt comfortable discussing overdose prevention with patients who use prescription opioids, and this comfort was associated with a higher probability of stocking naloxone (B = 0.392, 95%CI: 0.128, 0.655). Comfort discussing overdose prevention with people who use illicit opioids was lower (49.4%) and was not associated with stocking naloxone. CONCLUSION: There is scope to increase stocking of naloxone and comfort with overdose prevention, particularly through addressing comfort working with higher risk groups such as people who use illicit opioids.
RESUMEN
OBJECTIVE: This study aims to characterize the approaches to collecting, coding, and reporting health care and medicines data within Australian workers' compensation schemes. METHODS: We conducted a cross-sectional survey of data and information professionals in major Australian workers' compensation jurisdictions. Questionnaires were developed with input from key informants and a review of existing documentation. RESULTS: Twenty-five participants representing regulators (40%) and insurers (60%) with representation from all Australian jurisdictions were included. Health care and medicines data sources, depth, coding standards, and reporting practices exhibited significant variability across the Australian workers' compensation schemes. CONCLUSIONS: Substantial variability exists in the capture, coding, and reporting of health care and medicine data in Australian workers' compensation jurisdictions. There are opportunities to advance understanding of medicines and health service delivery in these schemes through greater harmonization of data collection, data coding, and reporting.

BACKGROUND AND AIMS: People with opioid use disorder (OUD) commonly experience pain including chronic pain. Despite the high prevalence, few studies have systematically examined the prevalence and correlates of pain among people seeking or receiving opioid agonist treatment (OAT) for OUD. This review aimed to determine the prevalence of pain in this population globally, and estimate the association between chronic pain and other demographic and clinical characteristics. METHODS: Electronic searches were conducted in three databases (Medline, Embase and PsycINFO) from the inception until October 2022. Eligible studies reported prevalence rates of current and/or chronic pain. Meta-analyses examining the main prevalence estimates were conducted by Stata SE 18.0, and comorbid clinical conditions were analysed by Review Manager 5.4. RESULTS: Fifty-six studies (n participants = 35 267) from sixty-seven publications were included. Prevalence estimates of current and chronic pain were reported in 27 (48.2%) and 40 studies (71.4%), respectively. Most studies were conducted in North America (71.4%, n = 40) and used cross-sectional designs (64.3%, n = 36). Meta-analyses revealed a pooled prevalence of 60.0% (95% confidence interval [CI]: 52.0-68.0) for current pain and 44.0% [95% CI: 40.0-49.0] for chronic pain. Chronic pain was positively associated with older age (mean deviation of mean age: 2.39 years, 95% CI: 1.40-3.37; I2 = 43%), unemployment (odds ratio [OR] = 0.57, 95% CI: 0.42-0.76; I2 = 78%), more severe mental health symptoms (e.g. more severe depression (standardised mean difference [SMD] of mean scores: 0.45, 95% CI: 0.20-0.70; I2 = 48%) and anxiety symptoms (SMD: 0.52, 95% CI: 0.17-0.88; I2 = 67%), and hepatitis C (OR = 1.41, 95% CI: 1.03-1.94; I2 = 0%). No association was observed between chronic pain and the onset and type of OAT, geographic location, study design, survey year, participant age or use of specific pain assessment tools. CONCLUSIONS: There appears to be a high prevalence of pain among people seeking or receiving opioid agonist treatment for opioid use disorder compared with the general population, with positive associations for older age, unemployment, hepatitis C and the severity of some mental health symptoms.
RESUMEN
Background: The World Health Organization seeks to eliminate viral hepatitis as a public health threat by 2030. This review and meta-analysis aims to evaluate the effectiveness of programs for hepatitis B and C testing and treatment in community pharmacies. Methods: Medline, Embase, Cochrane CENTRAL, and Global Health were searched from database inception until 12 November 2023. Comparative and single arm intervention studies were eligible for inclusion if they assessed delivery of any of the following interventions for hepatitis B or C in pharmacies: (1) pre-testing risk assessment, (2) testing, (3) pre-treatment assessment or (4) treatment. Primary outcomes were proportions testing positive and reaching each stage in the cascade. Random effects meta-analysis was used to estimate pooled proportions stratified by recruitment strategy and setting where possible; other results were synthesised narratively. This study was pre-registered (PROSPERO: CRD42022324218). Findings: Twenty-seven studies (4 comparative, 23 single arm) were included, of which 26 reported hepatitis C outcomes and four reported hepatitis B outcomes. History of injecting drug use was the most identified risk factor from pre-testing risk assessments. The pooled proportion hepatitis C antibody positive from of 19 studies testing 5096 participants was 16.6% (95% CI 11.0%-23.0%; heterogeneity I2 = 96.6%). The pooled proportion antibody positive was significantly higher when testing targeted people with specified risk factors (32.5%, 95% CI 24.8%-40.6%; heterogeneity I2 = 82.4%) compared with non-targeted or other recruitment methods 4.0% (95% CI 2.1%-6.5%; heterogeneity I2 = 83.5%). Meta-analysis of 14 studies with 813 participants eligible for pre-treatment assessment showed pooled attendance rates were significantly higher in pharmacies (92.7%, 95% CI 79.1%-99.9%; heterogeneity I2 = 72.4%) compared with referral to non-pharmacy settings (53.5%, 95% CI 36.5%-70.1%; heterogeneity I2 = 92.3%). The pooled proportion initiating treatment was 85.6% (95% CI 74.8%-94.3%; heterogeneity I2 = 75.1%). This did not differ significantly between pharmacy and non-pharmacy settings. Interpretation: These findings add pharmacies to the growing evidence supporting community-based testing and treatment for hepatitis C. Few comparative studies and high degrees of statistical heterogeneity were important limitations. Hepatitis B care in pharmacies presents an opportunity for future research. Funding: None.
RESUMEN
BACKGROUND: The most recent formulation of buprenorphine treatment is extended-release depot injections (BUP-XR) that are administered subcutaneously by health care professionals. This study aimed to observe treatment outcomes of BUP-XR delivered in standard practice during a 96-week follow-up period in a community setting. METHODS: This study is an extension of the CoLAB study, a prospective single-arm, multicentre, open label trial (N=100, 7 sites in Australia) among people with opioid dependence who received monthly injections of BUP-XR to evaluate the retention in treatment. Participants were followed for 96 weeks, comprising 48 weeks of the CoLAB study followed by a 48-week extension. RESULTS: Of 100 participants at baseline, 47 were retained on BUP-XR at 96 weeks. The median time retained on monthly depot was 90 weeks. Heroin use (adjusted OR=0.19, P=0.012) in the month prior to baseline was associated with lower odds of retention on BUP-XR. Older age at first opioid use (adjusted OR= 1.08, P=0.009) and longer duration in OAT at baseline (adjusted OR= 1.12, P=0.001) were associated with increased retention. Prevalence of past four-weeks opioid use was estimated at 4% at 96 weeks of treatment (prevalence 0.04, 95%CI: 0.00-0.11) compared to 15% at baseline. Quality of life and medication treatment satisfaction improved over time for those retained in treatment. CONCLUSION: This is one of the few studies to describe long term (96 week) retention in treatment with BUP-XR in a community setting. It displayed retention rates with 47% of participants completing 96 weeks of treatment with BUP-XR. Patient reported outcomes suggest improvements in client wellbeing. FUNDING: Indivior.

Objectives: To describe existing tools for screening patients for unstable housing in a healthcare setting. Methods: A literature search was completed to retrieve articles published in the last 10 years on screening patients for unstable housing in a healthcare setting. Results: The current literature on screening patients for homelessness in healthcare settings describes a variety of tools administered by a range of healthcare providers, but all are based in the United States. Conclusion: The studies revealed the potential for effective screening in healthcare settings and positive engagement of patients and providers with screening. Key areas for future research include innovative methods of screening and evaluation of reliability and validity for a broader range of tools.
