Background
Substance use disorder (SUD) is a problematic pattern of substance use leading to clinically significant impairment or distress.
SUD may result from the use of a variety of substances including medications (whether prescribed, non-prescribed, opioid or non-opioid), or other legal or illicit substances (e.g. alcohol, cocaine).
Substance use disorders may be referred to by the specific substance involved such as Alcohol Use Disorder, Cocaine Use Disorder, Opioid Use Disorder and Cannabis Use Disorder. If an individual has more than one SUD at a time, it is known as polysubstance use disorder.
When a SUD is identified, we must consider the impact on entitlement and treatment for the compensable injury.
For opioid medication management and tapering, end this procedure and instead follow the 4-7 Opioid management procedure.
Determine if there is a SUD
A variety of information may highlight the possibility of issues with substance use:
- It may present as behavioural concerns which are impacting participation in treatment or return to work, such as:
- A pattern of being late for or missing appointments.
- Worker is uncooperative or demonstrates inconsistent participation, even when present.
- Their behaviour limits their ability to participate in medical treatment safely (i.e. arrives for treatment in an impaired state).
- Claim documentation may show indicators of substance use issues including:
- Frequency of medication refills suggesting misuse of prescribed medication.
- Notation from treatment providers about reports of substance use or presentation, including documentation of a diagnosis or recommendations for treatment.
- Information directly from the worker or their representatives about use of substance or request for treatment
When a SUD is suspected, investigate it further:
- Complete a brief review (e.g., six months) of prescription receipts on file and/or medical records for the approved medication and any mention of other substances the worker is taking/using.
- Speak with the worker or representative and ask:
- Has the worker discussed any concern with substance use, do they feel they have substance use issue or have they taken any steps to address their substance use concerns?
- Contact the current service providers to review your concerns. If there are concerns regarding a prescribed medication, the prescribing physician should be contacted. Ask:
- Is there a diagnosis of a SUD? Are there signs it is impacting their treatment or recovery?
- Collaborate on a treatment plan for the SUD (refer to treatment section).
- Consider if an additional assessment is required to diagnose the SUD or determine if the SUD is caused by the compensable injury/accident. If further information is required, consider:
- Substance Use Assessment (see heading below).
- Comprehensive Psychological Assessment
- Psychiatric IME.
- MC or PC referral.
Refer to the Medical and Psychology Consultant referral section below and procedure 4-1 Medical testing, referrals and program support for more information.
Make the additional entitlement decision
Entitlement may be made at any point in the process, dependent upon the medical documentation. A Medical Consultant or Psychological Consultant review is not always required to determine compensability.
Consider if the SUD should be accepted outright, on an aggravation basis, or denied. The findings of a CPA, PIME or Substance Use Assessment can help make the appropriate entitlement decision if the information available on file isn't sufficient.
Entitlement should be considered when:
- The medical documentation provides a medical opinion from an assessing or treating physician or psychologist, Medical Consultant or Psychological Consultant that there is a diagnosed SUD, and
- The diagnosis is causally related to the injury.
In rare cases, it may be reasonable to provide treatment for the SUD before entitlement is verified when the substance use is clearly presenting as a significant barrier to recovery from a compensable injury. Typically, a substance use assessment should be used in these cases. When someone is in active addiction, the validity of other assessments such as a CPA or IME may be impacted, so an assessment may not be possible until stabilization is achieved through some treatment or intervention.
Determine the treatment required for the SUD
Treatment for a SUD may be considered when it is compensable or when it is not compensable but is a barrier to RTW or treatment. When treatment is required:
- Explain to the worker that continued entitlement to wage replacement and medical aid benefits is dependent on their participation in the necessary assessments and treatment program. Ensure the worker understands that not participating could result in a suspension of benefits under section 54 of the Workers' Compensation Act (WCA).
- Refer to any assessments and implement any outstanding treatment recommendations.
- Collaborate with the treatment provider on the suitable treatment plan.
Suitable treatment may include:
- Medication TaperingWhen there are concerns with prescribed medications collaborate with the prescribing physician on a plan, including tapering if needed. If a medication management plan is needed, refer to opioid procedure and consult with HCS Consultant for approval of the MMP..
- Counselling and regular family physician check ins.
- Community programsSuch as Alcoholics Anonymous, Narcotics Anonymous, and other peer-led self-help groups may be offered as an adjunct to other treatment however given the anonymity of these groups, you will not be able to obtain any collateral information for the claim from them. Likewise, release of any claim information to them, without worker consent, would not be permitted. As a result, it is important the treatment plan be monitored by a treatment provider (GP, Psych, etc.).
- Outpatient substance use program.If an outpatient program is being considered, make a substance use assess and treat referral.
The substance use assessment, or a treating provider may recommend a program. When referred for a program, the WCB contracted provider will determine the specific program requirements. These may include:
- Outpatient Substance Use program
- Detox (standalone)
- A four-week substance use program with detox
- Aftercare services with two streams:
- Basic- offers weekly group support
- Enhanced- offers weekly one-on-one sessions, weekly group support sessions, access to the mental health/substance use resource navigators, access to the Safe and Sound protocol and voluntary monitoring objective urine toxicology and alcohol breath testing.
- Inpatient Substance Use program
- If an inpatient program has been recommended by the treatment provider, first refer for a substance use assessment if one has not already been done. If an inpatient program is still required following the substance use assessment, consult with HCS for approval.
Note: When a treatment program (inpatient or outpatient program) is provided for a non-compensable condition, it is provided on a one-time basis only.
If the SUD is non-compensable and is not presenting a barrier to RTW then treatment may include community supports such as counselling, Narcotics Anonymous (NA)/Alcoholics Anonymous (AA). It should be encouraged that the worker speak to their family doctor as no WCB intervention is required in these instances. The decision maker can proceed with a referral through community supports to locate alternate community services in Alberta.
Monitor treatment and progress and determine benefits
Maintain regular biweekly contact with the worker during treatment. Address any concerns that arise (i.e. missed appointments, not participating in treatment).
Review the treatment progress and discuss with the treatment providers as needed. Outpatient programs with the SUD contracted provider will provide an initial report, progress report and discharge report.
If treatment is not progressing, consider if alternate treatment planning is required. Another formal assessment is usually not required in these instances. Consider also whether MC or PC referral is needed.
In the case of aggravation of a pre-existing SUD, the goal is to return them to their baseline functioning, which then allows recovery from the other compensable injury. The aggravation is then considered resolved.
Benefits during treatment
Review for appropriate benefits while in treatment.
For a compensable SUD, pay temporary total disability (TD01) or temporary partial disability (TD02) benefits biweekly during the treatment program. If a worker is receiving wage loss supplement benefits (i.e. ELP, TEL or TPD), TD01 or TD02, benefits can be paid during the treatment program, provided the treatment or related restrictions remove the worker from active employment.
Consider eligibility for other appropriate benefits during the treatment program (e.g., travel and subsistence allowance).
For a non-compensable SUD, consider the following when determining if wage loss benefits (i.e., TD01/TD02, existing wage loss or none) are payable:
- Are wage replacement benefits (i.e., TD or VR) currently being paid?
- Does treatment for the SUD remove the worker from active work or actively looking for work?
- If so, benefits can be paid during the treatment program.
If a worker leaves WCB-funded treatment for a non-compensable SUD on their own or is removed because of their behaviour and cannot finish the program, they may not meet the requirements to receive ongoing wage loss. Refer to procedure 3-3 Duty to cooperate.
Discharge and post discharge management
Upon discharge review the report. If treatment was:
- Successful, confirm the worker's fitness for work and work restrictions, and implement the return-to-work plan. Review for change in wage loss benefits (i.e., re-employment benefits).
- Not successful for a compensable SUD refer to a Psychological or Medical Consultant for further recommendations and consider section 54 of the WCA if there have been repeated relapses or failure to complete the program for any reason.
- Not successful for a non-compensable SUD, call the worker to discuss the next steps in their plan. Explain that treatment for the SUD will not be re-offered, however, the worker is still entitled to benefits and services relating to recovery and return to work for their compensable injury. Explain continued payment of benefits for the work-related injury is dependent on the worker's participation in the return-to-work plan.
Note: When treatment was provided for a non-compensable substance disorder and the worker was unsuccessful in recovery, typically no further treatment is offered. In rare cases, a second and final treatment program can be considered in consultation with the supervisor, if the merits of the individual cases have substantially changed since the first treatment program and success is a strong possibility.
Determine whether you will provide benefits for any aftercare programming. Length of this programming offered by the treating provider may range from as little as 30 days up to 1-year, depending on the program and the worker’s individual needs. Additional no-cost programming may include Alcoholics Anonymous and Narcotics Anonymous. Discuss with your Supervisor how much programming will be covered, if any, then provide that entitlement decision in a custom letter.
When we accept the entitlement as an aggravation of a pre-existing SUD and the worker relapses into addiction, the claim is not reopened unless there is also a worsening of their other compensable conditions. Benefit eligibility would be driven off the status of the compensable condition but may include treatment for the SUD when the compensable condition has deteriorated to the point the work restrictions have changed.
If the worker is expected to be employable after the treatment discharge, then ensure the appropriate rehabilitation/vocational services (e.g., occupational rehabilitation, Supported Job Search (SJS), pain management program, etc.) start immediately, if not already started.
The offer for medical and/or vocational assistance must remain open to the worker once the substance use issue is no longer a barrier to rehabilitation.
Consider the delay of recovery and if cost relief applies. The period of cost relief removed should equal the length of treatment program where the worker was not attending concurrent treatment for the SUD.
If a worker self-discharges from WCB funded treatment due to a non-compensable SUD and/or is removed due to their conduct and therefore is unable to complete the WCB-funded treatment review procedure 3-3 Duty to Cooperate.
Medical or Psychology Consultant referral
Consider a referral to a Medical or Psychology Consultant when there is conflicting medical evidence, or disagreement on a treatment plan/progress. When there are concerns with medications or the medical information in question is from a physician or psychiatrist, a medical consultant rather than psychological consultant should be used
Before making the consultant referral ensure the following information is available on the claim for their review:
- The completed prescription medication intake summary (if completed and relevant).
- A list of medications related to the compensable injury.
- Indicators that may suggest a SUD.
- All concerns identified by service providers.
Request that the consultant:
- Provide a review on whether there is evidence that documents a diagnosis of a SUD prior to the date of accident work injury.
- Comment on which SUD's are current and whether medical documentation supports a relationship to the DOA treatment or injury in cases where multiple SUD diagnoses are provided.
- Call the treating provider to discuss if substance use is an issue or a barrier to medical recovery or return to work, and to confirm if they will support treatment for a potential SUD, if identified.
- Obtain recommendations from the prescribing and/or treating physician(s) or treating psychologist recommend treatment or further assessment, if required.
- Comment on whether recovery has been or could be prolonged due to the SUD.
Note: A Consultant cannot provide a diagnosis and determine causation when those opinions have not already been provided. Rather, the Consultant may weigh conflicting evidence and provide an opinion on those opinions provided by the treating physician(s) or psychologist.
Review the Consultant documentation and recommendations to consider any changes to entitlement. Determine if the SUD is:
- Confirmed, make the additional entitlement decision for the SUD if it hasn't been made already.
- Possible but further evaluation is required, complete any referrals for additional investigations as needed.
- Not considered and no further evaluation is required continue to monitor the claim for any changes which may impact the case plan.
Substance Use Assessment
A substance use assessment will provide a diagnosis to confirm whether there is a substance use disorder, and it will provide treatment recommendations to address the concerns. While it may help resolve a conflict of medical opinion, it will not provide answers to questions of causation. It is specific for substance use and will not confirm other psychological or psychiatric diagnoses.
