Impacts of the COVID-19 pandemic on enrollment in medications for opioid use disorder (MOUD) in Vancouver, Canada: An interrupted time series analysis.

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.

Incremental expenditures attributable to daily dispensation and witnessed ingestion for opioid agonist treatment in British Columbia: 2014-20.

BACKGROUND AND AIM: While daily witnessed opioid agonist treatment (OAT) ingestion is common in British Columbia (BC), Canada, and elsewhere, sparse evidence supports this resource-intensive practice. Many settings across North America relaxed restrictions for take-home dosing during the COVID-19 pandemic and have reported consistent or improved patient outcomes. This study measured excess expenditures attributed to daily witnessed pharmacy dispensing compared with weekly or biweekly dispensation schedules. DESIGN, SETTING AND PARTICIPANTS: This study was a population-level retrospective analysis. We included all methadone, buprenorphine/naloxone and slow-release oral morphine dispensations in BC from 1 January 2014 to 30 December 2020. A total of 24 357 107 OAT dispensations among 51 195 unique individuals with 122 793 person-years of follow-up were included during the study period. MEASUREMENTS: Total expenditures for each person-week of OAT with an estimated expenditure under two scenarios are as follows: (1) a weekly dispensation scenario and (2) a biweekly dispensation scenario. FINDINGS: We estimated excess expenditures attributable to current dispensing practices of between $38 million (2014) and $47.4 million (2018) compared with a hypothetical weekly dispensing schedule, and $43.9 million (2014) to $54.9 million (2018) compared with biweekly dispensing. The majority of these expenditures (58-64%) were attributed to pharmacy dispensing fees ($23 million in 2014 to $30 million in 2018 compared with weekly dispensing; $26.6 million in 2014 to $34.7 million in 2018 compared with biweekly dispensing). CONCLUSION: Daily witnessed opioid agonist treatment ingestion results in more than $30 million in excess expenditures annually in the province of British Columbia, Canada compared with the costs of weekly or biweekly dispensation schedules.

Impact of COVID-19-related regulatory changes on nationwide access to buprenorphine: An interrupted time series design.

Background: The impact of COVID-19-related healthcare changes on access to buprenorphine (BUP) nationwide in the US is unknown. Methods: We conducted an interrupted time series with the IQVIA LRx database. The study timeline included BUP prescriptions from 52 weeks before (2/23/19-2/21/20) to 52 weeks after (4/4/20-4/2/21) the initial pandemic period (2/22/20-4/3/20). Segmented regression estimated relative changes in total milligrams (MG) of BUP available per week nationwide at 1, 26, and 52 weeks post-initial-pandemic. We evaluated treatment disruptions in previously stable patients, defined as ≥6 months of BUP prescriptions. Results: A total of 31 617 849 prescriptions were included. Total MG BUP dispensed increased at 1 and 26 weeks and then returned to baseline trends at 52 weeks post-initial pandemic period (4.1% [95% CI: 3.7,4.5], 2.1% [1.5,2.6], 0.1% [-0.6,0.9]). Stably-treated patients saw a decrease in 7-, 14-, and 28-day treatment disruptions at 52 weeks post-initial-pandemic period (-21.6% [-25.6,-17.7]; -10.8% [-16.3,-5.3]; -27.3% [-33.0,-21.6]). Men retained an increase in MG BUP compared to women at 52 weeks (0.7% [0.01,1.4] versus -0.6% [-1.5,0.2]). Younger age groups (18-29 years and 30-39 years) had a decrease in MG BUP at 52 weeks compared to expected baseline trend (-16.6 [-24.2, -9.0]; -1.6 [-3.0, -0.1). Patients with Medicaid demonstrated an increase in MG BUP at 52 weeks (8.3% [6.3,10.3]). MG BUP prescribed by APP prescribing increased by over 140 000 mg per week prior to the pandemic and continued to increase. Conclusions: Regulatory changes around buprenorphine prescribing facilitated patient access to buprenorphine during the pandemic.

Evaluating interventions to facilitate opioid agonist treatment access among people who inject drugs in Toronto, Ontario during COVID-19 pandemic restrictions.

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.

Impact of telemedicine on retention in Medications for Opioid Use Disorder (MOUD) treatment with buprenorphine in the times of COVID-19 pandemic: A retrospective chart review

This study reviewed the impact of telemedicine on treatment retention in Medications for Opioid Use Disorder (MOUD) with buprenorphine treatment program during the coronavirus disease 2019 (COVID-19) pandemic. Electronic health records of active patients in MOUD with buprenorphine treatment program were reviewed from July 1, 2019, to June 30, 2020. Data were divided into four groups of 3-months' time points to calculate and compare treatment retention in the baseline, pre-COVID, and in-COVID groups. The percentage of treatment retention with a 95% confidence interval was calculated using University of California San Franciso- Clinical and Translational Science Institute (UCSF-CTSI) sample size calculator tool. This study presents data suggesting that telemedicine is efficacious in retaining patients in MOUD. Telemedicine is an alternative to face-to-face treatment delivery for MOUD with buprenorphine treatment. It should be available to provide services after the pandemic as well. (PsycInfo Database Record (c) 2022 APA, all rights reserved) Impact Statement Addressing Opioid Use Disorder (OUD) is essential to reduce individual and societal harms associated with drug overdoses. Because of the need for social isolation and social distancing related to coronavirus disease 2019 (COVID-19), in-person encounters in Medications for Opioid Use Disorder (MOUD) with buprenorphine treatment programs were not feasible. This study suggests telemedicine as an alternative to in-person meetings and is efficacious in retaining patients in MOUD with buprenorphine treatment programs during the COVID-19 pandemic.

COVID-19: A new barrier to treatment for opioid use disorder in the emergency department.

OBJECTIVE: Start Treatment and Recover (STAR) is an emergency department (ED) program that expands access to medication for opioid use disorder by identifying patients with opioid use disorder and offering ED-initiated buprenorphine/naloxone and rapid access to outpatient treatment. We sought to determine the impacts of the coronavirus disease 2019 pandemic on STAR and the patients with opioid use disorder it serves. METHODS: We conducted a retrospective review of records comparing 2 periods: pre-pandemic (February 1, 2019-February 29, 2020) and pandemic (March 1, 2020-May 31, 2020). Variables evaluated included the number of STAR enrollments, ED census, percentage of census screening positive for opioid use disorder, number and percentage of ED overdose visits, and overdose fatalities by month. All analyses were conducted using 2-sample t tests to calculate the mean and 95% confidence intervals (CIs). RESULTS: Comparing the pre-pandemic to the pandemic period, the mean monthly ED visits decreased from 5126.9 to 3306.7 (difference = -1820.3; 95% CI, -3406.3 to -234.2), STAR mean monthly enrollments decreased from 9.7 to 1.3 (difference = -8.4; 95% CI, -12.8 to -4.0), and statewide monthly opioid-related fatalities increased from 9.4 to 15.3 (difference = 5.9; 95% CI, 0.8 to 11.1). However, the percentage of individuals who presented to the ED with opioid use disorder or overdose remained unchanged. CONCLUSION: Although overall ED visits declined during the pandemic period, the percentage of patients presenting with opioid use disorder or overdose remained constant, yet there was a dramatic decline in enrollment in ED-initiated medication for opioid use disorder and an increase in statewide monthly opioid-related fatalities. Strategies to maintain medication for opioid use disorder treatment options must be implemented for this vulnerable population during the ongoing pandemic.

Buprenorphine Microdose Induction for the Management of Prescription Opioid Dependence.

Prescription opioid dependence remains a major source of morbidity and mortality in the United States. Patients previously on high-dose opioids may poorly tolerate opioid tapers. Current guidelines support the use of buprenorphine therapy in opioid-tapering protocols, even among patients without a diagnosis of opioid use disorder. Buprenorphine microinduction protocols can be used to transition patients to buprenorphine therapy without opioid withdrawal. From November 2019 to April 2020, we transitioned 8 patients on high-dose prescribed opioids for pain to sublingual buprenorphine-naloxone using a microdose protocol without any evidence of precipitated withdrawal. Six of these patients remain on buprenorphine-naloxone and report improved analgesia. Because of its simplicity, the buprenorphine microinduction protocol can be easily adapted for telemedicine and may help to prevent unnecessary clinic visits and opioid-related admissions in the setting of social distancing regulations during the coronavirus 2019 pandemic.

The impact of family engagement in opioid assisted treatment: Results from a randomised controlled trial.

BACKGROUND: Family interventions in substance use disorders (SUD) treatment is limited despite the evidence for benefits. Providing family interventions is hampered by patient resistance, social stigma, logistics and factors related to the capacity of the treatment programmes. AIMS: The purpose of the study was to examine the association between family engagement in treatment, and opioid use defined by percentage negative opioid screen and rate retention in treatment defined by completion of study period. METHODS: Data from a 16-week outpatient randomised controlled trial (RCT) of 141 adults with opioid use disorder (OUD) receiving Opioid Assisted Treatment (OAT) using buprenorphine/naloxone film (BUP/NX-F) was, used to examine the association between family engagement in and opioid use and rate of retention in treatment. Multiple logistic regression was, applied to examine the independent prediction of family engagement on opioid use and rate retention in treatment. RESULTS: Family engagement was significantly associated with retention in treatment (Spearman's rho 0.25, p < 0.01) and was subsequently found to increase the likelihood of retention in treatment by approximately 3-fold (adjusted odds ratio (OR) 2.95, 95% CI 1.31-6.65). CONCLUSION: Family engagement in treatment is an independent predictor of retention in treatment but not opioid use in adults receiving OAT. It is, recommended that SUD treatment programmes integrate family related interventions in mainstream treatment. Delivering a personalised multicomponent family programme using digitised virtual communications that has been increasingly utilised during the Covid-19 pandemic is highly suggested.

Remote buprenorphine-naloxone initiation as an essential service for people with chronic pain and opioid dependence during the COVID-19 pandemic: Case reports, clinical pathways, and implications for the future.

Many health care professions have reacted swiftly to the COVID-19 pandemic. In-person care has been ramped down and telemedicine/telehealth has been thrust to the forefront of clinical care. For people living with chronic pain and often concomitantly dealing with opioid-related issues, this is a time of great stress. With population-wide movements to shelter in place, people living with pain are more isolated, more stressed, and more vulnerable to mental health concerns like depression and anxiety that can increase pain-related suffering. This article presents two case reports of patients struggling with chronic pain and opioid dependence in which a telemedicine-based buprenorphine-naloxone conversion was chosen as a treatment option by two Canadian programs: The Transitional Pain Service at the Toronto General Hospital in Toronto, Ontario, and The Opioid Deprescribing Program in Calgary, Alberta. Both cases presented highlight the use of telemedicine during the COVID-19 pandemic and suggest that there will be substantial need for these services well beyond the apex of the crisis. A buprenorphine-naloxone home induction protocol is presented and we provide insight into important lessons learned regarding the appropriate selection of patients with chronic pain struggling with opioid use disorder for buprenorphine-naloxone conversion. The provision of health care during the COVID-19 pandemic has rapidly forced practitioners to evolve novel health care practices, and these changes will have long-term implications.

De nombreuses professions de santé ont réagi rapidement à la pandémie de COVID-19. Les soins en personne ont diminué, tandis que la télémédecine et la télésanté ont été propulsées au premier plan des soins cliniques. Pour les personnes vivant avec la douleur chronique, souvent confrontées de manière concomitante à des problèmes liés aux opioïdes, il s'agit d'une période de grand stress. Avec les mouvements de confinemen de la population mis en place, les personnes vivant avec la douleur sont plus isolées, plus stressées et plus vulnérables aux problèmes de santé mentale comme la depression et l'anxiété, qui peuvent augmenter la souffrance liée à la douleur. Cet article présente deux rapports de cas de patients aux prises avec la douleur chronique et la dépendance aux opioides où la conversion à la buprénorphine-naloxone par télémédecine a été choisie comme option de traitement par deux programmes canadiens : Le Service de la douleur transitoire de l'Hôpital général de Toronto, en Ontario, et le Programme de déprescription des opioides à Calgary, Alberta. Les deux cas présentés mettent en évidence l'utilisation de la télémédecine pendant la pandémie de COVID-19 et indiquent qu'il y aura un besoin important pour ces services bien au-delà du sommet de la crise. Un protocole d'induction de la buprénorphine-naloxone à domicile est présenté et nous donnons un aperçu des seignemens tirés quant à la selection appropriée de patients souffrant de douleur chronique et d'un trouble lié à l'usage d'opioïdes pour la conversion à la buprénorphine-naloxone. La prestation de soins de santé durant la pandémie de COVID-19 a rapidement obligé les praticiens à mettre au point de nouvelles pratiques de soins de santé, et ces changements auront des implications à long terme.

Opioid substitution therapy with buprenorphine-naloxone during COVID-19 outbreak in India: Sharing our experience and interim standard operating procedure.

Coronavirus disease 2019 (COVID-19) has been declared as a pandemic by the World Health Organization on March 11, 2020. It has affected most countries of the world, including India. Both the disease and the unavoidable national response to it have posed unique challenges to our health-care system. A particular vulnerable group of patients is those with opioid dependence maintained on opioid substitution therapy (OST). These patients are pharmacologically dependent on the OST medication (buprenorphine, buprenorphine-naloxone combination [BNX], and methadone) for their healthy functioning and recovery. COVID-19 outbreak, lock-down, and difficult access to medical care, all are likely to induce stress and withdrawal, which is a potential risk for relapse among individuals with opioid dependence, who are anyway more vulnerable due to social, housing, living, and medical conditions. In this context, it is essential to re-strategize the existing OST services to adapt to the challenging circumstances. In this communication, we share our experience and formulate interim standard operating procedures (SOPs) for running a hospital-based OST service utilizing take-home BNX. The challenges, principles to meet the challenges, and interim SOPs are shared as being currently practiced in our center. Individual institutes, agencies, hospitals, and clinics running OST service with BNX can adapt these SOPs according to their characteristics, needs, demand, and resources; so long as, the basic principles are adhered to.
