Study Details

Study Description

Brief Summary

Attention deficit hyperactivity disorder (ADHD) is characterized by difficulties paying attention, poor impulse control, and hyperactive behaviors. It is associated with several health and social detrimental outcomes and leads to increased risks of criminality and recidivism. However, to date, ADHD treatment has been neglected in prison. This project will test the efficacy of ADHD treatment using a randomized controlled trial.

Condition or Disease Intervention/Treatment Phase
Phase 3

Detailed Description

This project aims to compare the efficacy of a three-month in-prison OROS-methylphenidate vs. placebo treatment on the severity of ADHD core symptoms. Secondary outcomes address additional important in-prison and post-prison aspects: 1) reduction in acute events in prison (e.g., disciplinary sanctions, violence, misuse of ADHD treatment), 2) evaluation of the risk of recidivism upon release, 3) three-month side effects of treatment, 4) in- and post-prison adherence to medication, 5) in- and post-prison study retention, 6) in- and post-prison costs-benefits of treatment, and 8) one-year recidivism. The post-prison part of the project will highlight long-lasting benefits of a treatment provided while people are detained.

To answer these research questions, we will use a randomized controlled trial. After randomization, the participants will undertake three months of treatment with OROS-MPH or placebo (1:1 ratio) while they are incarcerated. Upon release, all participants will be offered the possibility to have the treatment, but they will remain blinded regarding their initial study group. All of them will benefit of a cognitive-behavioral psycho-education program during detention and a cognitive-behavioral therapy after release.

Our RCT will provide empirical-based evidence of the benefits of in-prison ADHD treatment using different perspectives: Clinical, behavioral, recidivism-related, and economical. We expect that early detection and treatment of ADHD in prison will be an important public health opportunity and a cost-effective approach, likely to decrease the vulnerability of people living in detention and to promote pathways out criminal involvement.

Study Design

Study Type:
Interventional
Anticipated Enrollment :
150 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
This is a phase 3 parallel randomized controlled trial (1:1 ratio) of OROS-MPH vs. a placebo on a clinical outcome. Pparticipants will undertake three months of treatment while they are incarcerated. Upon release, all participants will be offered treatment in electronic monitors (without being unblinded on the treatment they received during detention). They will be followed-up for twelve months after release (total study duration: 15 months).This is a phase 3 parallel randomized controlled trial (1:1 ratio) of OROS-MPH vs. a placebo on a clinical outcome.

Masking:
Triple (Participant, Investigator, Outcomes Assessor)
Masking Description:
Participants will be blinded to the 3-month in-prison treatment. The research team and statistician will be blinded to the participants' group. The psychiatrist will be unblinded when participants are released. At that time of the study, all participants will be offered to have the treatment (OROS-MPH) without being unblinded regarding their initial group.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Pharmaceutical intervention (OROS-MPH)

Participants will receive OROS-MPH (Concerta® available in Switzerland as first-line treatment for ADHD). Dosages will be defined according to the Swiss Compendium. The psychiatrist (blinded during detention) will start with the smallest dosage (18 mg, Concerta®). The treatment will be monitored weekly the first month, and then monthly. The pharmacy of the Geneva University Hospitals will be in charge of over-encapsulating medications.

Drug: Concerta
Dosages of Concerta® will be defined according to the Swiss Compendium (from 18 to 72 mg/d). The psychiatrist will start with the smallest dosage (18 mg) and will adapt it on a weekly basis or on need, depending on tolerance (side effects measured at each visit), clinical response (subjective improvement felt by the patient in terms of attention, impulsivity, and hyperactivity), and according to the observations made by the professionals or patient's entourage in term of attention, impulsivity, hyperactivity, and for this project, behavioral problems. In general, the dose can be increased in 18 mg at weekly intervals. The treatment will be monitored weekly the first month, and then monthly, except for side effects which will be monitored daily in prison and every two weeks after release.

Placebo Comparator: Placebo

Drug: Placebo
The placebo will be strictly identical (same packaging, size no. 2 and color according to dosage, with no label). Procedure for adjustment of dosage will be the same as in the Concerta arm.

Outcome Measures

Primary Outcome Measures

  1. Severity of ADHD core symptoms [3 months]

    Conners Adult ADHD Rating Scale, range 0-78, higher score indicates worse outcome

Secondary Outcome Measures

  1. Number of acute events [3 months]

    Refusal to see doctors, nurses or lawyers, hunger strikes, self-harm events requiring a visit to the medical unit, fights requiring a visit to the medical unit, and disciplinary sanctions

  2. Structured Assessment of Protective Factors for Violence Risk [3 months]

    Dynamic risk assessment tool will be used to evaluate the risk of recidivism, score 0-30, higher score indicates better outcome

  3. Medication adherence [3 months and 12 months after release]

    Binary variable (yes=adherence to medication, no=absence of adherence to medication)

  4. Retention to study [12 months after release]

    Binary variable (yes=remain in the study, no=dropout from the study)

  5. Economic evaluation [3 months (medical and prison-related costs) and 12 months after release (prison-related costs)]

    Medical costs (costs of medical services used by patients (outpatient, emergency, and inpatient resources) and prison-related costs (disciplinary sanctions, use of resources in the prison and in prison staff and recidivism-related costs, average cost for one day in prison), two quantitative variables in Swiss francs.

  6. Recidivism [12 months after release]

    Data from the official Swiss criminal records (Federal Office of Statistics, Criminal Conviction Statistics), binary variable (yes=recidivism, no=no recidivism)

Other Outcome Measures

  1. Safety outcome [3 months]

    Side effects according to the Swiss compendium (number of side effects)
