Abstract
BACKGROUND AND AIMS Ukraine's Ministry of Health released urgent COVID-19 guidelines, allowing for early implementation of take-home dosing (THD) for opioid agonist therapies (OAT) such as methadone. Enrollment in OAT and retention in the program are the most effective HIV prevention strategies for people who inject drugs (PWID). This study aimed to evaluate the impact of Ukraine's COVID-19 emergency guidance on OAT treatment enrollment, retention on treatment and mortality. DESIGN AND SETTING Using Ukraine's national OAT registry for 252 governmental clinics across 25 regions, we conducted a 12-month comparative prospective cohort survival analysis. This study compared newly enrolled methadone patients within the initial 6 months following the COVID-19 guidance (COVID) with patients from the preceding year (pre-COVID) in a country with high adult HIV prevalence (1.2%) that is concentrated in PWID. PARTICIPANTS In the nation-wide sample of newly enrolled PWID in Ukraine, comprising 2798 individuals, 1423 were in the COVID cohort and 1375 were in the pre-COVID cohort. The majority were male (86.7%), with an average age of 39.3 years. MEASUREMENTS Primary outcomes were average monthly enrollment per cohort, treatment retention and mortality, with internal time-dependent predictors, including THD and optimal (> 85 mg) methadone dosing. RESULTS Relative to the pre-COVID period, the monthly average patient enrollment was statistically significantly higher during the COVID period (283.7 versus 236.0; P < 0.0001), where patients were more likely to transition to THD and achieve optimal dosing earlier. Significant differences were observed in the proportions of person-months on THD (41 versus 13%, P < 0.0001) and optimal dosing (38 versus 31%, P < 0.0001) between the COVID and pre-COVID cohorts. Predictors of treatment retention, expressed as adjusted hazard ratios (aHR), included early THD [aHR = 1.90, 95% confidence interval (CI) = 1.47-2.45], early optimal dosing (aHR = 1.71, 95% CI = 1.37-2.13) and prior methadone treatment (aHR = 1.39, 95% CI = 1.15-1.68). These factors persisted, respectively, in the pre-COVID (aHR = 2.28, 95% CI = 1.41-3.70; aHR = 1.84, 95% CI = 1.32-2.56; and aHR = 1.36, 95% CI = 1.06-1.74) and COVID (aHR = 1.91, 95% CI = 1.40-2.59; aHR = 1.61, 95% CI = 1.20-2.16; and aHR = 1.49, 95% CI = 1.08-1.94) cohorts. Survival did not differ significantly between the two prospective cohorts. CONCLUSION Ukraine's prompt adoption of early take-home dosing for opioid agonist therapies, such as methadone, following the emergency COVID-19 guidance appears to have increased enrollment into methadone and improved treatment retention for people who inject drugs without adverse effects on patient survival.

Russell C, Ashley J, Ali F, Bozinoff N, Corace K, Marsh DC, Mushquash C, Wyman J, Zhang M, Lange S. Examining inequities in access to opioid agonist treatment (OAT) take-home doses (THD): A Canadian OAT guideline synthesis and systematic review. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2024; 127:104343. [PMID: 38554565 DOI: 10.1016/j.drugpo.2024.104343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Revised: 01/08/2024] [Accepted: 01/30/2024] [Indexed: 04/01/2024]
Abstract
BACKGROUND Daily supervised Opioid Agonist Treatment (OAT) medication has been identified as a barrier to treatment retention. Canadian OAT guidelines outline take-home dose (THD) criteria, yet, OAT prescribers use their clinical judgement to decide whether an individual is 'clinically stable' to receive THD. There is limited information regarding whether these decisions may result in inequitable access to THD, including in the context of updated COVID-19 guidance. The current Canadian OAT THD guideline synthesis and systematic review aimed to address this knowledge gap. METHODS This systematic review included a two-pronged approach. First, we searched available academic literature in Embase, Medline, and PsychINFO up until October 12th, 2022, to identify studies that compared characteristics of individuals on OAT who had and had not been granted access to THD to explore potential inequities in access. Next, we identified all Canadian national and provincial OAT guidelines through a semi-structured grey literature search (conducted between September-October 2022) and extracted all THD 'stability' and allowances/timeline criteria to compare against characteristics identified in the literature search. Data from both review arms were synthesized and narratively presented. RESULTS A total of n = 56 guidelines and n = 7 academic studies were included. The systematic review identified a number of patient characteristics such as age, sex, race/ethnicity, marital status, housing, employment, neighborhood income, drug use, mental health, health service utilization, as well as treatment duration that were associated with differential access to THD. The Canadian OAT THD guideline synthesis identified many of these same characteristics as 'stability' criteria, underscoring the potential for Canadian OAT guidelines to result in inequitable access to THD. CONCLUSIONS This two-pronged literature review demonstrated that current guidelines likely contribute to inequitable OAT THD access due primarily to inconsistent 'stability' criteria across guidelines. More research is needed to understand differential OAT THD access with a focus on prescriber decision-making and evaluating associated treatment and safety outcomes. The development of a client-centered, equity-focused, and evidence-informed decision making framework that incorporates more clear definitions of 'stability' criteria and indications for prescriber discretion is warranted.

Abstract
BACKGROUND The drug toxicity crisis continues to accelerate across Canada, with rapid increases in opioid-related harms following the onset of the COVID-19 pandemic. We sought to describe trends in the burden of opioid-related deaths across Canada throughout the pandemic, comparing these trends by province or territory, age, and sex. METHODS We conducted a repeated cross-sectional analysis of accidental opioid-related deaths between Jan. 1, 2019, and Dec. 31, 2021, across 9 Canadian provinces and territories using aggregated national data. Our primary measure was the burden of premature opioid-related death, measured by potential years of life lost. Our secondary measure was the proportion of all deaths attributable to opioids; we used the Cochrane-Armitage test for trend to compare proportions. RESULTS Between 2019 and 2021, the annual number of opioid-related deaths increased from 3007 to 6222 and years of life lost increased from 126 115 to 256 336 (from 3.5 to 7.0 yr of life lost per 1000 population). In 2021, the highest number of years of life lost was among males (181 525 yr) and people aged 30-39 years (87 045 yr). In 2019, we found that 1.7% of all deaths among those younger than 85 years were related to opioids, rising to 3.2% in 2021. Significant increases in the proportion of deaths related to opioids were observed across all age groups (p < 0.001), representing 29.3% and 29.0% of deaths among people aged 20-29 and 30-39 years in 2021, respectively. INTERPRETATION Across Canada, the burden of premature opioid-related deaths doubled between 2019 and 2021, representing more than one-quarter of deaths among younger adults. The disproportionate loss of life in this demographic group highlights the critical need for targeted prevention efforts.

Abstract
BACKGROUND Opioid use disorder (OUD) and opioid-related harms are current health priorities in many high-income countries such as Canada. Opioid agonist therapy (OAT) is an effective evidence-based treatment for OUD, but access is often limited. AIMS To describe and compare OUD treatment policies across nine international jurisdictions, and to understand how they are situated within their primary care and health systems. METHODS Using policy documents, we collected data on health systems, drug use epidemiology, drug policies, and OUD treatment from Australia, Canada, France, Germany, Ireland, Portugal, Sweden, Switzerland, and Taiwan. We used the health system dynamics framework and adapted definitions of low- and high-threshold treatment to describe and compare OUD treatment policies, and to understand how they may be shaped by their health systems context. RESULTS Broad similarities across jurisdictions included the OAT pharmacological agents used and the need for supervised dosing; however, preferred OAT, treatment settings, primary care and specialist physicians' roles, and funding varied. Most jurisdictions had elements of lower-threshold treatment access, such as the availability of treatment through primary care and multiple OAT options, but the higher-threshold criteria of supervised dosing. CONCLUSIONS From the Canadian perspective, there are opportunities to improve accessibility of OUD care by drawing on how different jurisdictions incorporate multidisciplinary care, regulate OAT medications, remunerate healthcare professionals, and provide funding for services.

Abstract
BACKGROUND There are limited longitudinal data on national patterns of opioid agonist treatment (OAT). This study describes 10-year trends in the sales of OAT medicines in Australia. METHODS A descriptive and time-series analysis of methadone, sublingual (SL) buprenorphine (+/-naloxone), and long-acting injectable (LAI) buprenorphine sold in Australia between 2013 and 2022 was performed. Total units sold were converted into an estimate of the number of clients that could be treated over a 28-day period with that amount of medicine ('client-months'). RESULTS Between January 2013 and December 2022, the estimated number of client-months on: any OAT increased by 50 % to 53,501, methadone decreased (-8.5%), SL buprenorphine increased (+78%), and LAI buprenorphine increased substantially after September 2019. In January 2013, 78 % of OAT client-months received methadone. By December 2022, 48 % received methadone, 26 % SL buprenorphine, and 26 % LAI buprenorphine. Between 2013 to 2022, OAT client-months per capita were highest in the state of New South Wales. Over the study period, greater increases in OAT were observed in very remote areas (88%) compared to major cities (53%). The number of client-months in non-community pharmacy settings remained stable from 2013 to 2019/20, before increasing markedly. The introduction of LAI buprenorphine was associated with an immediate, sustained increase of 1,636 OAT client-months, and further increases of 190 OAT client-months each month. CONCLUSION Patterns of OAT have shifted over the last 10-years with buprenorphine (SL/LAI) now the most common OAT used in Australia. The introduction of LAI buprenorphine has expanded OAT access, particularly in non-community pharmacy settings, and in remote areas.

COVID-19-related flexibility in methadone take-home doses associated with decreased attrition: Report from an opioid treatment program in central Pennsylvania. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2023; 155:209164. [PMID: 37730014 DOI: 10.1016/j.josat.2023.209164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 09/12/2023] [Accepted: 09/12/2023] [Indexed: 09/22/2023]
Abstract
INTRODUCTION Pennsylvania saw a dramatic increase in take-home doses of methadone after the COVID-19 pandemic-related relaxation in regulations. We evaluated whether pandemic-initiated relaxation in take-home methadone dose regulations was associated with changes in attrition and urine drug test (UDT) results at one outpatient opioid treatment program (OTP) among adult patients treated with methadone for opioid use disorder (OUD). METHODS We analyzed aggregated, retrospective clinical practice data, using data abstracted from the OTP's electronic health record (EHR) on the number of patients treated with methadone, those allowed take-home doses, the number of take-home methadone doses dispensed, and the number and type of patient discharge ("attrition") from treatments for 12 months before (March 2019-February 2020; "pre-pandemic") and 12 months after (March 2020-February 2021; "pandemic") the regulatory changes took place. We also examined monthly aggregate data on the number of urine samples testing positive for amphetamines, cocaine, benzodiazepines or illicit opioids, and compared these findings between the pre-pandemic and pandemic periods. RESULTS Pre-pandemic, 229 patients were treated with methadone, compared to 278 patients during the pandemic period. They received 11,047 and 28,563 take-home daily-doses of methadone (p < 0.0001) during each assessment period, respectively. All-cause treatment attrition (discharge from the program for any reason) decreased from 27.1 % in the pre-pandemic to 15.5 % in the pandemic period (p < 0.001). Compared to pre-pandemic, during the pandemic period the urine toxicology testing showed reduced positivity rates for cocaine (26.4 % vs 18.9 %, p < 0.001), and oxycodone and morphine (1.8 % vs 1.1 %, p < 0.019), and increased for fentanyl (24.0 % vs 30.5 %, p < 0.007), without statistically significant changes for benzodiazepines or amphetamines. CONCLUSIONS The relaxation of regulations guiding take-home methadone doses accompanied reduced treatment attrition and favorable changes in urine toxicology results in one OTP. Allowing OTPs to apply flexible decisions regarding take-home methadone doses could improve treatment retention, outcomes, and, in turn, save lives.

BMJ Open 2023; 13:e070066. [PMID: 37857542 PMCID: PMC10603432 DOI: 10.1136/bmjopen-2022-070066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 09/26/2023] [Indexed: 10/21/2023] Open
Abstract
OBJECTIVE To determine if inappropriate tapering/discontinuation of opioids to Alberta patients occurred from mid-2013-2020, as unintended consequences of prescribing guidelines, regulations and policies in response to the North American opioid crisis. DESIGN A population-based, repeated cross-sectional time-series study. SETTING Alberta, Canada. PARTICIPANTS Residents of Alberta, Canada aged 18 and older who received an opioid dispense from a community pharmacy from 2013 to 2020. MAIN OUTCOME MEASURES The prevalence of potential rapid tapering was measured at a given date (reference day), enveloped by a data window. Dose changes were measured as oral morphine equivalents (OME) per patient, at multiple time points ('data window' around a reference day). Chronic recipients were identified, and their prescriptions were contrasted 90 days before and after the reference day to measure OME/day changes. RESULTS Approximately 9000 dispenses (totalling ~6 million OME) per day were analysed from 2013 to 2020. The total number of opioid recipients was highly cyclic in nature (peaking in winter). The number of chronic opioid recipients remained somewhat stable from ~70K in 2013 to ~86K at the end of 2020. The number of chronic high and very high dose recipients presented a significant decrease after 2017. Approximately 11%-12% of chronic high-dose recipients experienced potential rapid dose tapering at a rate of 50% or more prereference to postreference day at any given point of time. For chronic very high dose recipients, approximately 11.5% experience potential rapid dose tapering at a rate of 50% or more prereference to postreference day at any given point of time. Potential discontinuation remained constant and the interventions did not have a significant impact on the trend. CONCLUSION The evidence suggests that changes in prescribing guidelines were not associated with an increase of rapid opioid tapering/discontinuation in Alberta.

Panwala V, Joudrey P, Kowalski M, Bach P, Amram O. Changes to methadone maintenance therapy in the United States, Canada, and Australia during the COVID-19 pandemic: A narrative review. JOURNAL OF SUBSTANCE USE AND ADDICTION TREATMENT 2023; 152:209086. [PMID: 37270103 PMCID: PMC10232933 DOI: 10.1016/j.josat.2023.209086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 01/08/2023] [Accepted: 05/23/2023] [Indexed: 06/05/2023]
Abstract
INTRODUCTION In response to the COVID-19 pandemic, countries across the world made adaptations to policies regulating the provision of methadone maintenance therapy (MMT) to facilitate social distancing for health care providers and people in treatment. Many countries issued guidance about increasing take-home methadone doses after the onset of the pandemic. METHODS In this review, we compare the regulation of MMT prior to the pandemic in the United States, Canada, and Australia, analyze changes to treatment policy in the context of COVID-19, and review emerging data on treatment outcomes. RESULTS The United States only permits the prescription and disbursement of methadone for MMT treatment at federally designated opioid treatment programs (OTPs). Conversely, Australia and Canada operate on a community pharmacy-based distribution model, where patients can access methadone doses either in participating pharmacies or in some methadone clinics. CONCLUSION Given reports of similar treatment outcomes and increased patient satisfaction since the pandemic-related policy changes, some changes including increased receipt of take-home doses should be considered for incorporation into post-pandemic treatment policies and regulations.

Impacts of the COVID-19 pandemic on enrollment in medications for opioid use disorder (MOUD) in Vancouver, Canada: An interrupted time series analysis. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 118:104075. [PMID: 37271070 PMCID: PMC10201318 DOI: 10.1016/j.drugpo.2023.104075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 04/15/2023] [Accepted: 05/09/2023] [Indexed: 06/06/2023]
Abstract
BACKGROUND In anticipation of COVID-19 related disruptions to opioid use disorder (OUD) care, new provincial and federal guidance for the management of OUD and risk mitigation guidance (RMG) for prescription of pharmaceutical opioids were introduced in British Columbia, Canada, in March 2020. This study evaluated the combined impacts of the COVID-19 pandemic and counteracting OUD policies on enrollment in medications for OUD (MOUD). METHODS Using data from three cohorts of people with presumed OUD in Vancouver, we conducted an interrupted time series analysis to estimate the combined effects impact of the COVID-19 pandemic and counteracting OUD policies on the prevalence of enrollment in MOUD overall, as well as in individual MOUDs (methadone, buprenorphine/naloxone, slow-release oral morphine) between November 2018 and November 2021, controlling for pre-existing trends. In sub-analysis we considered RMG opioids together with MOUD. RESULTS We included 760 participants with presumed OUD. In the post-COVID-19 period, MOUD and slow-release oral morphine prevalence rates showed an estimated immediate increase in level (+7.6%, 95% CI: 0.6%, 14.6% and 1.8%, 95% CI: 0.3%, 3.3%, respectively), followed by a decline in the monthly trend (-0.8% per month, 95% CI: -1.4%, -0.2% and -0.2% per month, 95% CI: -0.4, -0.1, respectively). There were no significant changes in the prevalence trends of enrollment in methadone, buprenorphine/naloxone, or when RMG opioids were considered together with MOUD. CONCLUSIONS Despite immediate improvements in MOUD enrollment in the post-COVID-19 period, this beneficial trend reversed over time. RMG opioids appeared to have provided additional benefits to sustain retention in OUD care.

Clients' experiences on North America's first take-home injectable opioid agonist treatment (iOAT) program: a qualitative study. BMC Health Serv Res 2023; 23:553. [PMID: 37237256 DOI: 10.1186/s12913-023-09558-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Accepted: 05/16/2023] [Indexed: 05/28/2023] Open
Abstract
BACKGROUND To support public health measures during the COVID-19 pandemic, oral opioid agonist treatment (OAT) take-home doses were expanded in Western countries with positive results. Injectable OAT (iOAT) take-home doses were previously not an eligible option, and were made available for the first time in several sites to align with public health measures. Building upon these temporary risk-mitigating guidelines, a clinic in Vancouver, BC continued to offer two of a possible three daily doses of take-home injectable medications to eligible clients. The present study explores the processes through which take-home iOAT doses impacted clients' quality of life and continuity of care in real-life settings. METHODS Three rounds of semi-structured qualitative interviews were conducted over a period of seventeen months beginning in July 2021 with eleven participants receiving iOAT take-home doses at a community clinic in Vancouver, British Columbia. Interviews followed a topic guide that evolved iteratively in response to emerging lines of inquiry. Interviews were recorded, transcribed, and then coded using NVivo 1.6 using an interpretive description approach. RESULTS Participants reported that take-home doses granted them the freedom away from the clinic to have daily routines, form plans, and enjoy unstructured time. Participants appreciated the greater privacy, accessibility, and ability to engage in paid work. Furthermore, participants enjoyed greater autonomy to manage their medication and level of engagement with the clinic. These factors contributed to greater quality of life and continuity of care. Participants shared that their dose was too essential to divert and that they felt safe transporting and administering their medication off-site. In the future, all participants would like more accessible treatment such as access longer take-home prescriptions (e.g., one week), the ability to pick-up at different and convenient locations (e.g., community pharmacies), and a medication delivery service. CONCLUSIONS Reducing the number of daily onsite injections from two or three to only one revealed the diversity of rich and nuanced needs that added flexibility and accessibility in iOAT can meet. Actions such as licencing diverse opioid medications/formulations, medication pick-up at community pharmacies, and a community of practice that supports clinical decisions are necessary to increase take-home iOAT accessibility.

Abstract
Introduction: The COVID-19 pandemic has had wide economic, social, and health impacts, and has disproportionately affected individuals who were already vulnerable. Individuals who use opioids have dealt with evolving public health measures and disruptions while also dealing with the ongoing opioid epidemic. Opioid-related mortalities in Canada increased throughout the COVID-19 pandemic, but it is unclear to what extent public health measures and the progression of the pandemic contributed to opioid-related harms. Methods: To address this gap, we used emergency room (ER) visits recorded in the National Ambulatory Care Reporting System (NACRS) between 1 April 2017, and 31 December 2021, to investigate trends of opioid-related harms throughout the pandemic. This study also included semi-structured interviews with service providers in the field of opioid use treatment, to help contextualize the trends seen in ER visits and offer perspectives on how opioid use and services have changed throughout the COVID-19 pandemic. Results: Overall, the number of hospitalizations related to an opioid use disorder (OUD) decreased with progressing waves of the pandemic and with increasing severity of public health measures in Ontario. The rate of hospitalizations related to opioid poisonings (e.g., central nervous system and respiratory system depression caused by opioids) significantly increased with the progressing waves of the pandemic, as well as with increasing severity of public health measures in Ontario. Discussion: The increase in opioid-related poisonings is reflected in the existing literature whereas the decrease in OUDs is not. Moreover, the increase in opioid-related poisonings aligns with the observations of service providers, whereas the decrease in OUD contradicts the trends that service providers described. This discrepancy could be explained by factors identified by service providers, including the pressures on ERs during the pandemic, hesitancy to seek treatment, and drug toxicity.

Abstract
Public transport disruptions caused by the COVID-19 pandemic had wide-ranging impacts on the ability of individuals to access health care. Individuals with opioid use disorder represent an especially vulnerable population due to the necessity of frequent, supervised doses of opioid agonists. Focused on Toronto, a major Canadian city suffering from the opioid epidemic, this analysis uses novel realistic routing methodologies to quantify how travel times to individuals\220 nearest clinics changed due to public transport disruptions from 2019 to 2020. Individuals seeking opioid agonist treatment face very constrained windows of access due to the need to manage work and other essential activities. We find that thousands of households in the most materially and socially deprived neighbourhoods crossed 30 and 20-minute travel time thresholds to their nearest clinic. As even small changes to travel times can lead to missed appointments and heighten the chances of overdose and death, understanding the distribution of those most impacted can help inform future policy measures to ensure adequate access to care.

Methadone and buprenorphine-related deaths among people prescribed and not prescribed Opioid Agonist Therapy during the COVID-19 pandemic in England. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2022; 110:103877. [PMID: 36265326 PMCID: PMC9531664 DOI: 10.1016/j.drugpo.2022.103877] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 10/01/2022] [Accepted: 10/01/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND The coronavirus pandemic resulted in many changes which had the potential to impact mortality related to opioid agonist therapy (OAT; methadone, buprenorphine), including changes in the prescribing and dispensing of OAT and patterns of drug availability and use. We aimed to assess the impact of the first lockdown (initiated March 23rd 2020) on methadone- and buprenorphine-related deaths in England in people both prescribed and not prescribed OAT using data from the National Programme on Substance Abuse Deaths. METHODS This was a retrospective post-mortem toxicology study of OAT-related deaths which occurred in the 3-month period March 23rd to June 22nd in the years 2016-2020. Provisional data regarding numbers accessing treatment for opioid use disorder was provided by the National Drug Treatment Monitoring System. RESULTS We found a 64% increase in methadone-related deaths in March to June 2020 compared to March to June 2019 (2019 n = 96; 2020 projected n = 157). There were increases in the mortality rate of both in-treatment decedents (22% increase; 2019 n = 45; an exponential smoothing model of the 2016-19 trend [α=0.5] predicted 44 deaths in 2020, 55 were reported) and decedents not prescribed methadone (74% increase; 2019 n = 46; 2016-19 trend predicted 43 deaths in 2020, 80 were reported). There was no increase in buprenorphine-related deaths (2019 n = 9/529; 2020 n = 11/566). There were no changes in the numbers of deaths where other opioids or multiple substances were detected, or in methadone levels detected. Numbers of people accessing treatment for opioid use disorder in 2020 did not decrease relative to previous years (p >0.05). CONCLUSIONS Methadone-related deaths in non-prescribed individuals, but not prescribed individuals, increased considerably above the annual trend forecast for 2020 during the first COVID-19 lockdown in England. Further studies are thus needed to understand this difference.

Abstract
BACKGROUND Due to the coronavirus disease 2019 (COVID-19) pandemic, Health Canada issued an exemption to the Controlled Drugs and Substances Act (CDSA) on March 19, 2020, enabling pharmacists to act as prescribers of controlled substances to support continuity of care. Our study investigates utilization of the CDSA exemption by Ontario pharmacists with the intent to inform policy on pharmacist scope of practice and to improve future patient outcomes. METHODS We conducted a time-series analysis of pharmacist-prescribed opioid, benzodiazepine and stimulant claims data using Ontario Narcotics Monitoring System (NMS) data between January 2019 and December 2021. We used ARIMA modelling to measure the change to these classes of claims and to opioid claims containing quantities greater than a 30-day supply. RESULTS Postexemption, the average weekly number of pharmacist-prescribed opioid, benzodiazepine and stimulant claims rose by 146% (160 to 393 claims/week), 960% (49 to 515 claims/week) and 2150% (8 to 177 claims/week), respectively. There was a 2-week lag period between the time of announcement and the statistically significant increase in claims on April 5, 2020(p < 0.0001). The total number of claims for opioid quantities exceeding a 30-day supply decreased by 60%. Cumulative pharmacist-prescribed claims accounted for under 2% of the total NMS claims. INTERPRETATION Ontario pharmacists used the CDSA exemption but were prescribing at low rates. These findings suggest an effective change to pharmacy practice as the low rates show pharmacists used the exemption as a last line of defense. This may lead to further studies exploring treatment breaks during the COVID-19 pandemic and future changes to pharmacist scope to benefit patients.

Abstract
BACKGROUND Emergency contingency guidelines for opioid agonist treatment (OAT) were introduced in Ireland in March 2020, to ensure rapid and uninterrupted access to treatment while mitigating COVID-19 risk. The contingency guidelines deviated, across multiple clinical domains, from pre-pandemic clinical guidelines published in 2016. The objectives of this study are to (1) identify changes introduced to OAT clinical guidelines in Ireland during the pandemic; and (2) develop consensus on whether the new recommendations should be retained beyond the pandemic, using a national Delphi consensus methodology. METHODS Clinical guidance recommendations ('statements') were generated by comparing the newly established contingency guidelines with the national 2016 Clinical Guidelines for OAT. Over two rounds of on-line Delphi testing, a panel of experts (people currently accessing OAT, psychiatrists, general practitioners, community pharmacists, a nurse, a psychologist and support/key workers) independently rated their agreement with each statement and provided comments. Statements with a median score of 4 or 5 and a lower quartile of ≥4 were classified as having reached consensus. RESULTS Forty-eight panel members were recruited, with a high participation level at Round 2 (90%, n=43). Consensus was achieved for 12 of the 19 statements at Round 1. The 7 remaining statements were revised, with 2 new statements, resulting in 9 statements at Round 2. Four statements reached consensus at Round 2. The final list includes 16 clinical guidance statements; 9 relating to assessment, 3 to OAT drug choice and dosing, 1 to take-away doses, 2 to overdose prevention and 1 to the continuation of e-prescriptions. CONCLUSIONS A wide range of stakeholders involved in the delivery and receipt of OAT agreed on 16 clinical guidance statements for inclusion in OAT clinical guidelines as we move beyond the pandemic, rather than reverting to pre-pandemic guidelines. The agreed statements relate to facilitating safe access to OAT with minimal waiting time, supporting patient-centred care to promote health and well-being, and preventing drug overdose. Notably, consensus was not achieved for OAT drug dosage and frequency of urine testing during the stabilisation and maintenance phase of care.

Evaluating interventions to facilitate opioid agonist treatment access among people who inject drugs in Toronto, Ontario during COVID-19 pandemic restrictions. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2022; 104:103680. [PMID: 35447476 PMCID: PMC9005368 DOI: 10.1016/j.drugpo.2022.103680] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/22/2022] [Accepted: 03/30/2022] [Indexed: 12/01/2022]
Abstract
Background In March 2020, following a provincial COVID-19 emergency declaration, modifications to opioid agonist treatment (OAT) were introduced in Ontario, Canada to promote treatment access amid the pandemic and ongoing opioid overdose crisis. Modifications included federal exemptions to facilitate OAT prescription re-fills, extensions, and deliveries and interim treatment guidance emphasizing take-home (non-observed) doses and reduced urine drug screening for OAT patients. Methods We conducted an interrupted time series study using health administrative data from September 17th, 2019–September 21st, 2020, on 359 people who inject drugs with suspected opioid use disorder in Toronto, Ontario. We used segmented regression analyses to evaluate the joint effects of the provincial COVID-19 emergency declaration, federal OAT exemptions, and interim treatment guidance—all implemented between March 17th–23rd, 2020—on the weekly proportion of participants enrolled in OAT (i.e., ≥1 day(s) covered with methadone or buprenorphine/naloxone), with an opioid-related overdose (based on emergency department visits and hospitalizations), and who died (all-cause), and the weekly proportion of OAT-enrolled participants receiving take-home doses (i.e., ≥1 day(s) covered) and undergoing urine drug screening. Results Post-implementation, the interventions were associated with immediate absolute changes in OAT enrollment (+1.95%; 95% CI=0.04%–3.85%), receipt of take-home doses (+18.3%; 95% CI=13.2%–23.4%), and urine drug screening (-22.4%; 95% CI=[-26.9%]–[-17.9%]) and a gradual absolute increase of 0.56% in urine drug screening week-to-week (95% CI=0.27%–0.86%) beyond the pre-implementation trend. At 26 weeks post-implementation, OAT enrollment and urine drug screening approached pre-implementation levels whereas the increase in take-home doses was largely sustained (+15.0%; 95% CI=4.33%–25.6%). No post-implementation increases in opioid-related overdoses were observed. Death was not modelled (low event frequency). Conclusion Changes to OAT provision following provincial COVID-19 restrictions were associated with an immediate and sustained increase in take-home dose coverage among OAT-enrolled participants, without corresponding increases in opioid-related overdoses among all participants.
