Research has shown that 20–30% of prisoners meet the diagnostic criteria for attention-deficit hyperactivity disorder (ADHD). Methylphenidate reduces ADHD symptoms, but effects in prisoners are uncertain because of comorbid mental health and substance use disorders.
To estimate the efficacy of an osmotic-release oral system methylphenidate (OROS-methylphenidate) in reducing ADHD symptoms in young adult prisoners with ADHD.
We conducted an 8-week parallel-arm, double-blind, randomised placebo-controlled trial of OROS-methylphenidate versus placebo in male prisoners (aged 16–25 years) meeting the DSM-5 criteria for ADHD. Primary outcome was ADHD symptoms at 8 weeks, using the investigator-rated Connors Adult ADHD Rating Scale (CAARS-O). Thirteen secondary outcomes were measured, including emotional dysregulation, mind wandering, violent attitudes, mental health symptoms, and prison officer and educational staff ratings of behaviour and aggression.
In the OROS-methylphenidate arm, mean CAARS-O score at 8 weeks was estimated to be reduced by 0.57 points relative to the placebo arm (95% CI −2.41 to 3.56), and non-significant. The responder rate, defined as a 20% reduction in CAARS-O score, was 48.3% for the OROS-methylphenidate arm and 47.9% for the placebo arm. No statistically significant trial arm differences were detected for any of the secondary outcomes. Mean final titrated dose was 53.8 mg in the OROS-methylphenidate arm.
ADHD symptoms did not respond to OROS-methylphenidate in young adult prisoners. The findings do not support routine treatment with OROS-methylphenidate in this population. Further research is needed to evaluate effects of higher average dosing and adherence to treatment, multi-modal treatments and preventative interventions in the community.
We audited prescribing within our area to ascertain how widespread the practice of antipsychotic polypharmacy using clozapine was, and whether it was being carried out within existing standards, including those of high-dose monitoring when required.
Data on 169 patients were reviewed in year one, rising to 193 in year three. Around 30% of patients on clozapine received additional antipsychotic medication. A disturbingly low proportion of patients on clozapine whose antipsychotic polypharmacy brought them into the high-dose range were being monitored appropriately after three audit cycles (the proportion rose from 10% in cycle 1 to 28% in cycle 3). A wide range of additional antipsychotic medications was used.
Clozapine antipsychotic polypharmacy was prevalent at just below a third of all patients in this review. Prescribers should be alert to the fact that clozapine antipsychotic polypharmacy can push patients into the high-dose range and ensure appropriate monitoring.
