Context and Policy Issues

Opioids are a class of drugs that produce analgesic and central nervous system depressant effects that can also induce euphoria.1,2 Opioids include natural opiates (e.g., morphine, codeine) and synthetic or semi-synthetic opioids (e.g., oxycodone, fentanyl, methadone) and can take the form of prescribed pain medications or illegally produced or obtained substances2 Both prescribed and illegally obtained opioids can be associated with problematic use.1,2 Opioid use disorder (OUD) is defined within the Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association as a problematic pattern of opioid use leading to clinically significant impairment or distress.3 OUD is a chronic, relapsing type of substance use disorder characterized by periods of exacerbation and remission, with a persistent vulnerability for relapse2,3

OUD is associated with significantly increased rates of morbidity and mortality. According to Health Canada, the number of overdoses and deaths caused by opioids is on the rise and reflects a public health crisis.1 Recent national data indicate there were at least 3,987 apparent opioid-related deaths in 2017, and of those 92% were accidental; this corresponds to a death rate of 10.9 per 100,000 population.4 The rate of hospitalizations due to opioid poisoning increased 53 per cent between 2007-20018 and 2016-2017.5 This increase in opioid-related harms underscores the need to identify evidence-based treatment approaches.

Options for the clinical management of opioid use disorder range along a treatment intensity spectrum.6,7 Withdrawal management exists on the low intensity end of the treatment intensity spectrum; treatment options include tapered methadone or buprenorphine. Agonist therapies are moderate intensity treatments; treatment options include buprenorphine/naloxone or methadone. Specialist-led alternative approaches are high intensity treatments; treatment options include slow-release oral morphine. Including psychosocial or residential treatments can support each approach.7 All options can be implemented with or without supportive therapies that include psychosocial and residential treatments, and in conjunction with harm reduction strategies such as needle exchange programs.

The purpose of this review is to evaluate the guidelines for opioid addiction programs for the treatment of adults who are reducing or discontinuing opioids or undergoing opioid substitution therapy.

Research Question

What are the evidence-based guidelines regarding the use of opioid addiction programs for the treatment of adults who are reducing or discontinuing opioids or opioid substitution therapy?

Key Findings

Six evidence-based guidelines were identified regarding the use of programs for the treatment of opioid use disorders in adults. Included guidelines provide recommendations regarding the safety and clinical effectiveness of programs that address treatment, implementation, and adherence enhancement strategies. Two Canadian guidelines recommend initiating opioid agonist treatment with buprenorphine/naloxone where feasible as a first-line treatment option. This was a strong recommendation based on high quality evidence. Alternative strategies are recommended where buprenorphine/naloxone is not feasible, or where contraindications are identified. Psychosocial interventions aimed at reducing illicit drug use during detoxification and following completion include fostering social support (with the service provider, with peer groups and with existing network of family and carers) and use of contingency management.

Methods

Literature Search Methods

A limited literature search was conducted on key resources including PubMed, The Cochrane Library, University of York Centre for Reviews and Dissemination (CRD) databases, Canadian and major international health technology agencies, as well as a focused Internet search. Methodological filters were added to limit the retrieval to guidelines. Where possible, retrieval was limited to the human population. The search was also limited to English language documents published between January 1, 2013 and August 2, 2018.

Selection Criteria and Methods

One reviewer screened citations and selected studies. In the first level of screening, titles and abstracts were reviewed and potentially relevant articles were retrieved and assessed for inclusion. The final selection of full-text articles was based on the inclusion criteria presented in Table 1.

Table 1. Selection Criteria.

Selection Criteria.

Exclusion Criteria

Guidelines were excluded if they did not meet the selection criteria outlined in Table 1, they were duplicate publications, or were published prior to 2013. Guidelines with unclear methodology were also excluded.

Critical Appraisal of Individual Studies

The included guidelines were critically appraised by one reviewer with the AGREE II instrument.8 Summary scores were not calculated for the included studies; rather, a review of the strengths and limitations of each included study were described narratively.

Summary of Evidence

Quantity of Research Available

A total of 113 citations were identified in the literature search. Following screening of titles and abstracts, 108 citations were excluded and five potentially relevant reports were retrieved for full-text review. Twenty one potentially relevant publications were retrieved from the grey literature search for full text review. Of these potentially relevant articles, 20 publications were excluded for various reasons, and six guideline publications met the inclusion criteria and were included in this report. Appendix 1 presents the PRISMA9 flowchart of the study selection.

Summary of Study Characteristics

Additional details regarding the characteristics of included publications are provided in Appendix 2.

Study Design

Six evidence-based guidelines6,7,1013 were identified regarding the use of opioid addiction programs for the treatment of adults who are reducing or discontinuing opioids or opioid substitution therapy. All six guidelines were informed by systematic reviews of the evidence. The CRISM guideline represents an update of the BCCSU-CRISM guideline, and it is tailored from the provincial BC approach to a national approach.

Country of Origin

The Canadian Research Initiative in Substance Misuse (CRISM)7 and British Columbia Centre on Substance Use (BCCSU)-CRISM6 guidelines were published in Canada in 2018 and 2017, respectively. The American Pain Society – College on Problems of Drug Dependence (APS-CPDD) guidelines10 were produced in the United States (US) and published in 2014. The World Health Organization (WHO) guidelines11 were released in 2014 in Geneva, Switzerland as international guidelines. The two National Institute for Health and Care Excellence (NICE) guidelines12,13 were originally published in the United Kingdom (UK) in 2007 and revised in 2016 and 2014.

Patient Population

All six included guidelines provide recommendations for the treatment of adults with OUD.6,7,1013 Two guidelines were developed specifically for a particular population; the APS-CPDD guideline applies to individuals seeking methadone treatment in licensed treatment centres and the WHO guideline applies to those who are pregnant or postnatal.10,11 Overall, the population of interest for the CRISM, BCCSU-CRISM and NICE guidelines is general, although they include recommendations for specific sub-populations (e.g., one NICE (psychosocial) guideline includes recommendations for individuals in prison or detention centres).6,7,12,13

Interventions

Recommendations regarding the following interventions are made: patient screening procedures,10,11 patient education and support,10,12 and treatments (e.g., oral agonist and antagonist pharmacotherapies, withdrawal management strategies, psychosocial treatment interventions and supports, and residential treatment).7

Outcomes

The primary outcome of interest for the APS-CPDD guidelines is safety.10 The CRISM, BCCSD-CRISM, WHO and NICE (2014 and 2016) guidelines target clinical effectiveness (i.e., healthy outcomes for pregnant people,11 engagement in treatment,13 reduction/abstinence in use of drugs,12,13 reduced risk of relapse,13 completion of treatment,12 improvement in entry rate for naltrexone maintenance,12 use of other drugs,12 and severity of withdrawal12).

Summary of Critical Appraisal

The six evidence-based guidelines6,7,1013 were assessed using the AGREE II tool. All included guidelines were of relatively high quality, however there were limitations. Strengths of the guidelines are the overall objectives and populations to whom the guidelines apply are specifically described; guideline development groups included individuals from all relevant professional groups; the target users of the guidelines are clearly defined; systematic methods were used to search for evidence (2 guidelines included structured literature reviews with systematic methods,6,7 4 included systematic reviews1013); the criteria for selecting the evidence, the strengths and limitations of the body of evidence, and the methods for formulating the recommendations are clearly described; the health benefits, side effects, and risks have been considered in formulating the recommendations; there is an explicit link between the recommendations and the supporting evidence; the guideline was externally reviewed by experts prior to its publication; a procedure for updating the guideline is provided; the recommendations are specific and unambiguous; the different options for management of the condition or health issue are clearly presented; competing interests of guideline development group members have been recorded. These features may increase the reliability of the recommendations as they demonstrate sound methodology and make these publications less prone to biases.

The limitations of the guidelines included: the CRISM,7 BCCSU-CRISM,6 and APS-CPDD10 guideline development panels did not seek the views and preferences of the target population (patients, public, etc.) in the development of the guidelines.6,7,10 While study quality was assessed in all guidelines, the two NICE guidelines did not present the strength of the recommendation or describe the quality of the evidence associated with each recommendation.12,13 Regarding implementation, the APS-CPDD guideline does not include facilitators and barriers to its application, and advice and/or tools on how the recommendations can be put into practice are not provided.10 Furthermore, the CRISM and the WHO guidelines include a note that tools will be produced, however it is unclear if this has been done.7,11 While these implementation issues may make the guidelines more difficult to implement, they do not affect the trustworthiness of the recommendations. None of the included guidelines present monitoring or auditing criteria; all guidelines identify the funding body, however only the BCCSU-CRISM guideline explicitly reported that the views of the funding body have not influenced the content of the guideline,6 although this is not expected to introduce bias.

Additional details regarding the strengths and limitations of included publications are provided in Appendix 3.

Summary of Findings

The detailed recommendations, the quality of evidence on which the recommendations were based, and the strength of recommendations can be found in Appendix 4.

Guidelines

Screening

The APS-CPDD, WHO, and both NICE guidelines include recommendations regarding the use of screening to establish opioid use;1013 however, the recommended assessments vary in the degree of comprehensiveness. The WHO guideline panel recommends that health care providers for people who are pregnant or postpartum ask their patients about their use of substances at each antenatal visit, prior to offering comprehensive and individualized care.11 The NICE guidelines recommend that staff in mental health and criminal justice settings ask services users about illicit drug use, and that health care providers use biological testing as well as routine clinical questions to establish drug use I medical settings.12,13 For patients seeking methadone therapy, the APS-CPDD panel recommends comprehensive medical and behavioural risk screening including use of electrocardiography (ECG) to identify those with an elevated risk for methadone-associated arrhythmia.10 See Table 3 for detailed screening procedures.

Treatment

Regarding recommended treatment for opioid use disorder the two Canadian guidelines recommend opioid agonist treatment with buprenorphine-naloxone as the first-line treatment for OUD.6,7 Methadone is recommended for those who respond poorly to buprenorphine-naloxone.7 There are serious safety risks associated with use of methadone and the recommendations included in the APS-CPDD guideline are intended to represent measures that can be taken to promote safer use.10 Primarily, the APS-CPDD panel recommends that patients using methadone should be monitored for sedation, for QTc interval prolongation (using ECG), and for common opioid adverse effects (via face-to-face or phone assessment with patients within 3 to 5 days after initiating methadone, and within 3 to 5 days after each dose increase.10 The NICE psychosocial guidelines include recommendations regarding the care of people who misuse drugs, including discussing whether to involve their families and carers in the treatment process and respecting their autonomy and privacy rights.13

Withdrawal Management

Withdrawal management (or detoxification) alone is not recommended due to poor safety and effectiveness.6,7 This is consistent with the WHO guideline, which recommends that pregnant people with OUD continue or commence opioid maintenance therapy with methadone or buprenorphine rather than opioid detoxification, and refer those choosing detoxification to a medically supervised detoxification program. The NICE detoxification guideline identifies ccontraindications to detoxification as having a medical condition needing urgent treatment, being in police custody or short prison sentence, and presentation to acute or emergency setting for other conditions.

Adherence Support

Each guideline includes recommendations targeting improved adherence and engagement with the treatment program. These include recommendations regarding the support of informed decision making,13 involving the patient in care decisions,10,13 discussing social support,13 routinely offering information and referral to take-home naloxone programs and other harm reduction services,6 and the introduction of contingency management programs.13 For example, the APS panel recommends that before initiating methadone treatment, health care providers speak with patients about the goals of therapy, availability of alternative therapies, plans for monitoring and adjusting doses, and potential adverse effects.

Additionally, the CRISM recommendations support using “a stepped and integrated care approach, in which treatment intensity is continually adjusted to accommodate individual patient needs and circumstances over time,” (page E247) and allows for moving between treatments as needed or chosen. As part of a stepped approach, NICE recommends contingency management programs, whereby incentives (e.g., privileges, vouchers for goods or services) are offered as a contingency for each negative drug test.13 The NICE psychosocial guideline also includes the recommendation that the access to and choice of treatment should be the same whether treatment is being sought voluntarily or by legal requirement.13 For people in prison, the NICE guideline includes recommendations that treatment options should be comparable to those available in the community and that a therapeutic community developed specifically to treat drug misuse in the prison environment may be appropriate for those with significant drug misuse problems.13

Recommendations regarding treatment simplification and intensification, alternative and adjunct treatment options, adjunct harm reduction strategies, approaches to avoid, follow-up, medication interactions, education and support, social support and engagement with family and carers, opportunistic brief interventions, contingency management, staff training, community and residential treatment, detoxification, rapid detoxification, procedures following relapse, comorbid conditions, and contraindications were also identified. A detailed list of the recommendations in presented in Appendix 4.

Limitations

The included guidelines were high quality (Appendix 3), however, there were limitations related to gaps in the recommendations. For instance, no recommendations specifically addressed treatment of Indigenous populations. As part of the Public Health Emergency Response, the Government of Canada has committed to improving access to treatment for First Nations communities.1,14 Evidence informed treatment strategies that are culturally appropriate are needed.

Additionally, very clear and specific recommendations regarding the use of methadone and monitoring of adults who are not pregnant were identified; however, recommendations for methadone treatment protocols for those who are pregnant were less detailed. New treatment options are currently being developed. As the field evolves, these guidelines will need to be constantly updated to incorporate new evidence.

Conclusions and Implications for Decision or Policy Making

Six high quality evidence-based guidelines were identified regarding the use of opioid addiction programs for the treatment of adults who are reducing or discontinuing opioids or opioid substitution therapy. Where assessed, recommendations tended to be strong and were based on very low- to moderate-quality evidence.

It was recommended across guidelines that patients with suspected opioid use disorder receive confirmatory screening. One guideline provided detailed criteria for screening patients with ECG to identify risk factors for cardiac arrhythmia (i.e., QTc interval prolongation) prior to initiating methadone and following methadone dose changes. Guidelines recommend that service providers should offer education and counselling to patients contemplating treatment, and that treatment should be individually tailored, based on patient preferences, health risks, experience with previous treatment, treatment goals, and psychological, social, and occupational needs. Ongoing support and monitoring are recommended to assess safety/adverse effects and adherence.

One guideline recommended that methadone or buprenorphine should be offered as the first-line treatment for opioid detoxification, with the decision based on patient preferences and risk factors. Another guideline recommended that methadone should not be offered, or only offered with modified protocol for patients with prolonged QTc interval. Ultra-rapid detoxification and accelerated detoxification should not be routinely offered, and sedation for ultra-rapid detoxification is not recommended. Psychosocial interventions are a low intensity treatment option that should normally include contingency management, behavioural couples’ therapy, and cognitive behaviour therapy. Finally, guidelines recommend that treatment options should be widely accessible to treatment seeking Canadians, regardless of their context (e.g., rural areas, prison, health care settings).

Table 3Summary of Recommendations in Included Guidelines

RecommendationsStrength of Evidence and Recommendations
CRISM, 20187
First- and second-line treatment options
1.

“Initiate opioid agonist treatment with buprenorphine–naloxone whenever feasible, to reduce the risk of toxicity, morbidity and death, and to facilitate safer take-home dosing.” (pE250)

Strong recommendation, high quality evidence
2.

“For individuals responding poorly to buprenorphine–naloxone, consider transition to methadone treatment.” (pE250)

Strong recommendation, high quality evidence
3.

“Initiate opioid agonist treatment with methadone when treatment with buprenorphine–naloxone is not the preferred option.” (pE250)

Strong recommendation, high quality evidence
4.

“For individuals with a successful and sustained response to methadone who express a desire for treatment simplification, consider transition to buprenorphine–naloxone, because its superior safety profile allows for more routine take-home dosing and less frequent medical appointments.” (pE250)

Strong recommendation, moderate quality evidence
Alternative or adjunct treatment options
5.

“In patients for whom first- and second-line treatment options are ineffective or contraindicated, opioid agonist treatment with slow-release oral morphine (initially prescribed as once-daily witnessed doses) can be considered. Slow-release oral morphine treatment should be prescribed only by physicians with a Section 56 exemption to prescribe methadone, or following consultation with an addiction practitioner experienced in opioid agonist treatment with slow-release oral morphine.” (pE250)

Strong recommendation, moderate quality evidence
6.

“Offering withdrawal management alone (i.e., detoxification without immediate transition to long-term addiction treatment) should be avoided, because this approach has been associated with increased rates of relapse, morbidity and death.” (pE250)

Strong recommendation, moderate quality evidence
7.

“When withdrawal management (without transition to opioid agonist treatment) is pursued, provide supervised slow (> 1 mo) opioid agonist taper (in an outpatient or residential treatment setting) rather than a rapid (<1 wk) taper. During opioid-assisted withdrawal management, patients should be transitioned to long-term addiction treatment† to help prevent relapse and associated health risks.” (pE250)

Strong recommendation, moderate quality evidence
8.

“For patients with a successful and sustained response to opioid agonist treatment who wish to discontinue treatment (i.e., desiring medication cessation), consider a slow taper approach (over months to years, depending on the patient). Ongoing addiction care should be considered on cessation of opioid use.” (pE250)

Strong recommendation, moderate quality evidence
9.

“Psychosocial treatment interventions and supports should be routinely offered but should not be viewed as a mandatory requirement for accessing opioid agonist treatment.” (pE250)

Strong recommendation, moderate quality evidence
10.

“Oral naltrexone can also be considered as an adjunct medication if cessation of opioid use is achieved.” (pE250)

Weak recommendation, low quality evidence
Adjunct harm-reduction strategies
11.

“Information and referrals to take-home naloxone programs and other harm reduction services (e.g., provision of clean drug paraphernalia), as well as other general health care services, should be routinely offered as part of standard care for opioid use disorders.” (pE250)

Strong recommendation, moderate quality evidence
BCCSU/CRISM, 20176
Approaches to avoid
1.

Withdrawal management alone (i.e., detoxification without immediate transition to longterm addiction treatment*) is not recommended, since this approach has been associated with elevated rates of relapse, HIV infection and overdose death. This includes rapid (< 1 week) inpatient tapers with methadone or buprenorphine/naloxone.” (p12)

Strong recommendation, moderate quality evidence
Possible first-line treatment options
2.

“Initiate opioid agonist treatment with buprenorphine/naloxone whenever feasible to reduce toxicities and facilitate recovery through safer take-home dosing.” (p12)

Strong recommendation, high quality evidence
3.

Initiate opioid agonist treatment with methadone when treatment with buprenorphine/naloxone is not preferable (e.g., challenging induction).” (p12)

Strong recommendation, high quality evidence
4.

If withdrawal management is pursued, for most patients, this can be provided more safely in an outpatient rather than inpatient setting. During withdrawal management, patients should be immediately transitioned to long-term addiction treatment* to assist in preventing relapse and associated harms. See also #9. (p12)

Strong recommendation, moderate quality evidence
Adjunct or alternative treatment options
5.

For individuals responding poorly to buprenorphine/naloxone, consider transition to methadone. (p12)

Strong recommendation, high quality evidence
6.

“For individuals responding poorly to methadone, or with successful and sustained response to methadone desiring treatment simplification, consider transition to buprenorphine/naloxone.” (p12)

Strong recommendation, moderate quality evidence
7.

“For individuals with a successful and sustained response to agonist treatment desiring medication cessation, consider slow taper (e.g., 12 months). Transition to oral naltrexone could be considered upon cessation of opioids.” (p12)

Strong recommendation, moderate quality evidence
8.

“Psychosocial treatment interventions and supports should be routinely offered in conjunction with pharmacological treatment.” (p12)

Strong recommendation, moderate quality evidence
9.

“For patients wishing to avoid long-term opioid agonist treatment, provide supervised slow (> 1 month) outpatient or residential opioid agonist taper rather than rapid (< 1 week) inpatient opioid agonist taper. During withdrawal management, patients should be transitioned to long-term addiction treatment to prevent relapse and associated harms. Oral naltrexone can also be considered as an adjunct upon cessation of opioid use.” (p13)

“For patients who have been unsuccessful with first- and second-line treatment options, opioid agonist treatment with slow-release oral morphine (prescribed as once-daily witnessed doses) can be considered. Slow-release oral morphine should only be prescribed by experienced addiction practitioners who hold a Section 56 exemption to prescribe methadone or only after specialist consultation (e.g., RACE line). Practitioners who lack experience prescribing slow-release oral morphine for treatment of opioid use disorder, regardless of Section 56 exemption status, should consult with an experienced prescriber prior to initiating treatment.” (p13)

“If a person presenting for opioid detoxification also misuses alcohol, healthcare professionals should consider the following.
  • If the person is not alcohol dependent, attempts should be made to address their alcohol misuse, because they may increase this as a response to opioid withdrawal symptoms, or substitute alcohol for their previous opioid misuse.
  • If the person is alcohol dependent, alcohol detoxification should be offered. This should be carried out before starting opioid detoxification in a community or prison setting, but may be carried out concurrently with opioid detoxification in an inpatient setting or with stabilisation in a community setting.” (p14)
Not clear
“If a person presenting for opioid detoxification is also benzodiazepine dependent, healthcare professionals should consider benzodiazepine detoxification. When deciding whether this should be carried out concurrently with, or separately from, opioid detoxification, healthcare professionals should take into account the person’s preference and the severity of dependence for both substances.” (p14)Not clear
“Methadone or buprenorphine should be offered as the first-line treatment in opioid detoxification. When deciding between these medications, healthcare professionals should take into account:
  • whether the service user is receiving maintenance treatment with methadone or buprenorphine; if so, opioid detoxification should normally be started with the same medication
  • the preference of the service user” (p14)

“In this context, “addiction treatment” refers to continued care for opioid use disorder delivered by an experienced care provider, which could include pharmacological treatment (opioid agonist or antagonist treatment), evidence-based psychosocial treatment interventions (private or publicly-funded programs), residential treatment, or combinations of these treatments. In isolation, harm reduction services, low barrier housing and unstructured peer-based support would not be considered “addiction treatment.” Opioid agonist therapy can be provided as an outpatient or when individuals are admitted to inpatient addiction treatment.”6 p12
