New admissions (n = 120) to the Addiction Treatment Services (ATS) will be stabilized on methadone and randomly assigned to one of two induction conditions: 1) routine stepped care, or 2) low threshold stepped care. All participants will continue with routine stepped care in month 4. Treatment retention is the primary outcome measure, while drug use (measured via weekly urinalysis testing) is the major secondary outcome.
This randomized clinical trial will evaluate two induction strategies for helping out-of-treatment opioid abusers transition to methadone maintenance treatment. All study participants (n = 120) will be new admissions to the Addiction Treatment Services at Hopkins Bayview (ATS), stabilized on 80 mg of methadone, and randomly assigned to one of two study conditions. The experimental induction condition will receive low threshold stepped care (LTSC) for the first 3-month of treatment that reduces the counseling demands of maintenance treatment (i.e., one counseling session / month). This condition will be compared to routine stepped care (RSC) for the first 3-months, which provides escalating intensity of counseling schedules contingent on drug use or poor adherence. RSC is routine treatment at ATS. All participants will receive routine stepped care following the 3-month induction phase, and will have the opportunity to remain in treatment at ATS following study participation. Participation is for 4-months. Retention is the primary outcome. Participants will also submit urine samples weekly on a random schedule each month. We hypothesize that LTSC participants will exhibit better retention than RSC participants, and that both conditions will exhibit reductions in drug use compared to baseline.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 3-month counseling induction: routine care | Active Comparator | Participants assigned to this condition will receive routine stepped-care treatment at ATS. Participants will begin in Step 2 (one counseling session per week), and be advanced to higher intensity care based on missed counseling sessions and drug-positive urine samples. Participants advanced to Step 3 will be scheduled to attend 2 group counseling sessions per week (in addition to individual counseling), and those advanced to Step 4 will be scheduled to attend 8 group counseling sessions per week (in addition to individual counseling). Time of methadone dosing will be based on step of care. |
|
| 3-month counseling induction: low threshold | Experimental | Participants assigned to this treatment arm will receive low threshold counseling. These participants will be scheduled to attend one counseling session per month with their individual counselor for the first 3-months. Participants can attend more counseling sessions if they desire, and they can meet with program supervisors to address crisis situations. They can receive methadone dosing any time during the clinic hours (7:30 am-1:15 pm and 4:00 pm - 6:00 pm) |

|---|---|---|---|---|
| low threshold care | Behavioral | Low threshold care refers to a service delivery method that reduces the treatment demands for new admissions to substance abuse treatment. In the present study, participants will be scheduled to attend less counseling sessions, and will have greater access to methadone. |
| Measure | Description | Time Frame |
|---|---|---|
| treatment retention | The number of days patients remained in treatment over the 120 day study. | 120 days |
| Measure | Description | Time Frame |

| Drug use | Urinalysis testing is administered weekly, using a random testing schedule. Samples are tested for the presence of opioids, cocaine, and benzodiazepines | weekly observation for 120 days |

| stepped-based care | Behavioral | Stepped-based care is routine treatment at ATS. Participants begin a low intensity care, and are advanced to more intensive levels of care (i.e., more intensive schedules of counseling) based on urine samples and counseling adherence. |
