Surveys suggest that up to 80% of veterans with a persistent mental illness have a co-occurring substance use disorder. Substance abuse among this population is problematic and often results in poor engagement in treatment and thus, frequent hospitalizations and an unstable illness course. Regarding treatment engagement, data from a VA New Jersey facility indicated that 50% of those veterans discharged from the acute psychiatric hospital unit to outpatient care did not attend their initial screening appointment and another 30% dropped out within six weeks. To assist with the transition from inpatient to outpatient care, we previously developed an eight-week augmentation intervention entitled, Time-Limited Case Management (TLC). TLC integrates evidence-based interventions of 1) Dual Recovery Therapy; 2) Critical Time Intervention Case Management along with 3) Peer Support with the goal of assisting individuals with the transition from inpatient to outpatient care.
