Re-thinking patient stability for methadone in opioid treatment programs during a global pandemic: Provider perspectives

COVID-19 necessitated rapid changes in methadone take-home policies in opioid treatment programs (OTPs); these changes markedly contrast with existing, long-standing federal mandates on OTP rules about take-home methadone. OTP providers describe how these changes have affected clinical decision-making, equity in patient care, and workflow. We also discuss implications for medical ethics and patient autonomy. We provide suggestions for future research that will examine the impact of COVID-19 on OTP treatment and its patients, as well as the effect of making methadone take-home polices patient centered, all of which may foreshadow larger changes in the ways OTPs deliver their services.

Technology-assisted methadone take-home dosing for dispensing methadone to persons with opioid use disorder during the Covid-19 pandemic

IntroductionCovid-19 confers substantial risk for the >400,000 patients who receive methadone for the treatment of opioid use disorder (OUD) and methods for safely dispensing large quantities of methadone to patients are lacking. MethodsThis study evaluated the MedMinder “Jon”, an electronic and cellular-enabled pillbox that provides real-time monitoring to remotely manage take-home doses of methadone using a 12-week, within-subject, Phase II (NCT03254043) trial. We transitioned all participants from liquid to tablet methadone one week prior to randomization. Participants completed both treatment-as-usual and electronic pillbox conditions before choosing a condition in a final “choice phase”. We assessed feasibility, satisfaction, and safety outcomes during the exit interview. ResultsOverall, we randomized 25 participants, 24 (96.0%) completed >1 study session, and 21 (84.0%) completed the exit interview. We dispensed 167.92 g (1,974 doses) of methadone. Participants would use the pillbox again (86.3%) and recommend it to others (95.4%). Overall, 52.4% selected the pillbox in the choice condition and those who did not cited issues related to study requirements. Less than 1% of pillbox alerts were for medication being consumed outside the dosing window and we observed no evidence of actual or attempted methadone diversion. DiscussionWe were able to adequately manage patients who would not otherwise qualify for large quantities of take-home methadone when we dispensed methadone tablets via a secure pillbox. The integration of a commercially available pillbox into routine clinic operations increases opportunity for dispensing medication. Our data support remote monitoring of methadone take-home doses and may inform clinic practices related to Covid-19.

Increased flexibility in methadone take-home scheduling during the COVID-19 pandemic: Should this practice be incorporated into routine clinical care?

In the context of the COVID-19 pandemic and the state of emergency that the government of Spain declared, the rapid adaptation of health services is of paramount importance to preserve access to and continuity of service delivery. This research note underscores the importance of ensuring a sufficient quantity of methadone take-home doses for patients on methadone maintenance treatment (MMT) to maximize their adherence to government-imposed lockdown restrictions and social distancing measures designed to curtail the spread of SARS-CoV-2. We evaluate the impact of COVID-19 on take-home medication (number of days provided) in a methadone clinic in Barcelona (Catalonia, Spain). This work conveys that we should consider maintaining the take-home practices that we adopted in response to the pandemic, even after the pandemic has abated.

Mobilizing community support in people receiving opioid-agonist treatment: A group approach

This descriptive study evaluates a novel group intervention designed to help opioid-dependent patients in medication-assisted treatment identify and recruit drug-free individuals to support recovery efforts. The Social Network Activation Group works with patients who are actively using drugs and resistant to including drug-free family or friends in treatment. The group encourages patients to attend structured recovery, religious, or recreational activities in the community to find recovery support. For those with underutilized support, motivational interviewing and skills training are used to help patients resolve ambivalence and include family or friends in the treatment plan. Patients earn up to one methadone take-home each week that they attend the group and verify activity participation. They complete the group after introducing a drug-free family member or friend to their counselor. This study reports on a sample of 66 patients referred to this group as part of intensive outpatient treatment. Patients attended 71% of scheduled sessions and participated in a M = 4.3 activities. Mutual-help support groups (64%) and church (28%) were the activities most often attended. Thirty-six percent brought in a drug-free family or friend to meet their counselor. Family members were the most common choice (67%). The results demonstrate preliminary feasibility and mixed efficacy of the Social Network Activation Group for this highly select sample of patients, and provide additional evidence that many patients possess drug-free family or friends who are willing to support recovery efforts.

Achievement of take-home dose privileges is associated with better-perceived sleep and with cognitive status among methadone maintenance treatment patients

Objectives. Methadone maintenance treatment (MMT) patients may achieve up to a 2-week privilege of methadone take-home doses (THD), which is associated with considerable responsibility. MMT patients are characterized as having poor sleep quality and low cognitive states. We studied sleep indices and cognitive status with respect to THD privileges. Methods. A sample of 123 MMT patients stratified by THD groups was studied. Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the cognitive Clock Drawing Test (CDT) were performed. Results. Thirty-one of 123 patients never had any THD and 92 did (25 had the maximum of 2 weeks). The never THD had history of longer duration of opiate usage and a shorter period in MMT. They had the highest rates of poor sleep (80.6%, PSQI > 5), daily sleepiness (“fall asleep while talking”) (41.9%), and impaired cognitive status (58.1%, CDT < 3), while those who had 2-week privileges had the lowest (56, 8, and 28%, respectively). Logistic regression characterized THD patients as no-benzodiazepine and no-cocaine, short opiate usage duration, low ADHD scores, and no cognitive impairment (CDT = 3) and its interaction with treatment duration. Conclusion. Privileges that reflect patients’ abstinence and rehabilitation were also expanded to be associated with better cognitive states. These finding confirm the THD dispensing performance. Including CDT as part of the decision for dispensing THD may be considered.

Evaluation of ongoing oxycodone abuse among methadone-maintained patients

Prevalence of prescription opioid abuse has increased dramatically in recent years in the United States generally, and a similar pattern of increasing prescription opioid use has also been noted among patients seeking treatment for opioid dependence. This study presents results from an internal quality assurance project conducted by an outpatient methadone maintenance (MM) treatment clinic which sought to examine the extent of ongoing oxycodone abuse among patients that might be going undetected with current urinalysis-testing methods. One hundred five MM patients provided 437 urine samples over a 6-week period. Samples were analyzed using the clinic's usual enzyme multiplied immunoassay test (EMIT) opiate assay (300 ng/ml opiate cutpoint) and a supplemental oxycodone test strip (100 ng/ml oxycodone cutpoint). The EMIT assay identified only 6% (20/437) of samples as positive for oxycodone, whereas the oxycodone test strip indicated that 19% (83/437) tested positive for recent oxycodone use. Inspection of patient characteristics revealed that oxycodone users were more likely to report a prescription opioid as their primary drug at intake, be in MM treatment for a significantly shorter duration, and provide significantly more opioid- and cocaine-positive urine samples. Overall, these data illustrate the potential importance of monitoring for ongoing oxycodone use in MM clinics. Although future efforts should examine this question using more rigorous experimental methods, findings from this initial project have implications for clinical issues such as evaluating patient stability in treatment, making medication-dosing decisions, and determining patient eligibility for methadone take-home privileges.

Effects of urine testing frequency on outcome in a methadone take-home contingency program

We examined the effects of urine testing frequency on treatment outcome in a contingent methadone take-home program. Study patients who submitted<80% opiate and/or cocaine positive urines during a 5-week baseline received 60 mg methadone throughout the study, submitted urine samples on Monday, Wednesday, and Friday, and were randomized into one of three take-home incentive conditions. Study patients could receive three take-home doses per week if one urine sample randomly selected each week (Weekly; n=16) or each month (Monthly; n=18) was negative for opiates and cocaine. Take-homes for Random Drawing control patients ( n=19) were determined weekly independent of urine test results. Subjects in the Weekly group showed an immediate increase from baseline in percentage of drug-free urines; those in the Monthly group showed a gradual increase over the first 3 months; and those in Random Drawings showed a decline in percentage of drug-free urines over time. The percentage of patients with sustained (8 or more weeks) opiate and cocaine abstinence was 56.6, 38.9 and 10.5% for Weekly, Monthly and Random Drawing groups, respectively ( P<0.002). These results confirm that methadone take-homes contingent on drug-free urines prevent a decline in treatment performance over time and suggest that abstinence can be sustained with urine testing conducted as infrequently as once a month.

A 12-year follow-up of a methadone medical maintenance program.

Methadone Medical Maintenance (MDM) is an alternative for treatment of stable methadone maintained individuals. It involves a monthly physician's visit, at which methadone take-home doses are dispensed to last until the next appointment. The safety and efficacy of this treatment modality is currently under investigation. The purpose of this study was to evaluate the long-term safety and efficacy of MDM in a methadone program in Baltimore. A sample of 21 patients was enrolled in the study and followed for 12 years. They were evaluated once a month by a primary care physician affiliated with a methadone clinic who collected urine toxicology samples and dispensed the monthly methadone dose. The results showed that only 6 (28.6%) patients dropped out during the 12 years of the study. Twelve (0.5%) of 2,290 urine samples collected were positive for drugs. No methadone overdose or diversion was observed. Participants reported significant improvement in their quality of life. The results of this study support the safety and efficacy of medical maintenance of stable methadone maintained individuals.

Oral and intravenous methadone use: some clinical and pharmacokinetic aspects

A sample of 15 patients participating in an injectable methadone trial and of 15 patients in an oral methadone maintenance treatment, who admitted injecting part or all of their methadone take-home doses, were compared to 20 patients in maintenance treatment who use methadone exclusively by mouth. The present study confirms the poorer general health, the higher levels of emotional, psychological or psychiatric problems, the higher use of illicit drugs, and the higher number of problems related to employment and support associated with the use of the intravenous mode of administration of methadone. As expected, due to the shunt of metabolism in the gut wall and of the liver first-pass effect, higher concentration to dose ratios of ( R)-methadone, which is the active enantiomer, were measured in the intravenous group (23% increase). This difference reached an almost statistically significant value ( P=0.054). This raises the question whether the effect of a higher methadone dose could be unconsciously sought by some of the intravenous methadone users.

Contingent reinforcement sustains post-detoxification abstinence from multiple drugs: A preliminary study with methadone patients

This study examined the efficacy of a urinalysis-based contingency management program for preventing relapse to abused drugs following a brief residential detoxification. Fourteen methadone maintenance patients who were chronic benzodiazepine users were enrolled in a 7-day inpatient benzodiazepine detoxification and randomly assigned to receive Contingency Management (N=7) or Standard Care (N=7) therapy upon return to outpatient methadone treatment. In the Contingency Management condition, a methadone take-home dose or a US $25 voucher (patient's choice) could be earned for each urine sample submitted on a Monday, Wednesday or Friday that was free of opiates, cocaine and benzodiazepines. Data analysis and interpretation focused on within-group post-hoc differences due to group differences on employment and legal status, potentially confounding baseline variables. Repeated measures analysis of variance showed that Contingency Management patients submitted significantly more drug-free urine samples during the intervention compared to pre-detoxification (p<0.01), whereas no significance changes were observed from pre- to post-detoxification in the Standard Care patients. Employment and legal status of patients may have facilitated response to contingency management procedures, but did not prevent relapse when contingency management procedures were withdrawn. Overall, these preliminary results suggest that abstinence-based contingency management is a promising strategy for preventing relapse to multiple drugs of abuse in a subset of methadone maintenance patients when abstinence has been initiated through brief inpatient treatment.

Use of Methadone Take-Home Contingencies with Persistent Opiate and Cocaine Abusers

This study investigated conditions under which methadone patients with urinalysis evidence of persistent multiple drug abuse would respond to take-home incentive procedures. Study subjects submitted > or = 80% opiate and/or cocaine positive urines during a 5-week baseline period (M, W, F urine testing) while maintained on 60 mg methadone. Doses were raised to 80-100 mg methadone under blind conditions and subjects were randomly assigned to receive methadone take-home doses under one of three conditions: (a) earn a 1-day take-home privilege for each opiate and cocaine-free test delivered (daily contingent condition), (b) three negative test results required for the first take-home privilege, with each subsequent negative test earning one take-home dose; a positive test reset the contingency back to three again (weekly contingent condition), or (c) a control group that did not receive take-home privileges (no take-home control). Five of 21 subjects (24%) assigned to a contingent take-home intervention (2 from condition a, 3 from condition b) showed marked reductions in drug use and delivered 4 or more consecutive weeks of drug-free urines during a 16-week intervention. No subject in the control group met these criteria. Percent positive urines decreased by 14% and 18% from baseline in daily and weekly contingency groups, respectively, compared to a decline of 2% in the no take-home control group (planned contrast of means p < .07 and .05, respectively). Thus, the study demonstrated that take-home incentives can be effective for reducing during-treatment use of opiates and cocaine in methadone patients with a poor prognosis related to their persistent multiple drug use.

Contingent methadone take-home doses reinforce adjunct therapy attendance of methadone maintenance patients

Two studies utilized within-subjects designs to determine whether take-home methadone doses can reinforce adjunct therapy attendance of drug abuse patients. These studies varied the reinforcement density and the schedule of methadone take-home doses. In Study 1, patients ( n = 10) either could or could not receive a take-home following each therapy session. Study 2 patients ( n = 15) could either earn take-homes following each therapy session attended (i.e., 2 take-homes per week) or could earn one take-home dose following each attendance to two consecutive sessions attended. In both studies experimental conditions alternated during three-week blocks of time. Across studies, any reinforcement by take-home doses produced more attendance at therapy sessions than that observed in the no reinforcement condition. Take-home incentive effects were strongest when each of the two weekly therapy sessions was reinforced by a methadone take-home dose. Increased attendance was not associated with reduced drug use, due perhaps to high rates of pre-study drug use and limited therapy duration. Contemporary opioid abusers present with multiple problems that methadone was never intended to treat. The present studies illustrate a method by which methadone treatment can improve the likelihood of delivering other services that may prove effective in treating some of these problems.

Treatment Process and Relapse to Opioid Use During Methadone Maintenance

A general framework for studying drug abuse treatment process factors is presented, and components are then used to predict relapse to opioid use during treatment in methadone maintenance. Major domains of the treatment process research framework include client variables at entry, program characteristics, treatment events, and client outcomes. The analyses rely on the use of proportional hazards models to identify significant outcome predictors in a sample of 590 methadone maintenance clients from 21 clinics in the Research Triangle Institute/Treatment Outcome Prospective Study (RTI/TOPS) data system who remained in treatment at least 3 months. The analyses were performed on the total sample and separately on clients from three groups of clinics classified on the basis of the distribution of client relapse rates and tenure in treatment. Relapse rates were related to dosage level, client monitoring with urinalyses, and methadone take-home privileges in some clinics, and hence, these time-varying treatment events were important factors in treatment outcomes. Even at entry to treatment, some measures were found to be related to how the client later performed during treatment. Finally, it was also found that the particular area of professional speciality of the staff making client diagnosis at intake and preparing treatment plans was associated with client outcomes.

Contingent reinforcement for benzodiazepine-free urines: evaluation of a drug abuse treatment intervention.

This study evaluated contingent reinforcement for benzodiazepine-free urines as a therapeutic intervention for promoting reduced use of supplemental benzodiazepine drugs among methadone maintenance outpatients. Ten methadone maintenance patients were selected for participation on the basis of positive urinalysis results. During a 12-week intervention period these patients were offered clinic privileges, including monetary payments or methadone take-home doses, contingent on benzodiazepine negative urinalysis test results. Eight of ten participants responded to the intervention with at least 2.5 weeks of consecutive clean urines. An increase in benzodiazepine-negative tests during the contingent reinforcement period was significant for the group as a whole. The results suggest that more widespread application of contingent reinforcement procedures may be warranted in drug abuse treatment clinics.

Reducing benzodiazepine self-administration with contingent reinforcement

Abstract The purpose of the present study was to determine whether drug self-administration by methadone maintenance clients can be influenced by offering methadone clinic privileges contingent upon reductions in drug use, and to compare the reinforcing efficacy in this regard of two different clinic privileges. Eight methadone maintenance clients who had histories of supplemental benzodiazepine use participated. In order to transfer illicit drug use to the treatment clinic, clients were prescribed diazepam, 20 mg/day, at the methadone clinic dispensary. Following assessment of baseline diazepam use, clients were offered, during 6-week blocks of time, either the chance to obtain a single methadone take-home dose or the chance to self-regulate their methadone dose for a single day. These privileges were contingent upon refusing prescribed diazepam at the clinic. During baseline weeks, 95.6% of available diazepam doses were requested. When take-home privileges were available, only 11.2% of diazepam doses were requested, while when dose self-control was available, 69.7% of doses were requested. The study showed that the supplemental drug use of methadone maintenance clients can be influenced by clinic privileges which are available contingent upon reductions of drug use. The medication take-home privilege was more effective as a reinforcer than was limited methadone dosage self-control. Methadone clinic privileges can be used as intervention tools to promote desirable therapeutic behavior change in drug addicts, and in particular to promote reductions in supplemental drug use.
