Sources: 2. Developments: 2. Inpatient rehabilitation programs for substance use disorders involve structured timelines and specific clinical phases. While industry standards often utilize 30, 60, or 90-day models, research suggests that treatments lasting fewer than 90 days may yield limited results for many individuals. The process typically begins with an intake and admission phase focused on medical evaluations, substance use history, and mental health assessments to tailor treatment plans. The initial week often includes orientation, meeting clinical teams, and a medically supervised detoxification period, which generally lasts between three and seven days to manage withdrawal. Following detoxification, the therapeutic phase utilizes consistent daily routines, including individual and group therapy, educational workshops on relapse prevention, and skill-building activities such as stress management. The goal of these programs is to provide stability and discharge planning to reduce the risk of relapse. ## Timeline ### 2026-08-28: Inpatient drug rehab processes and first-week expectations Inpatient drug rehab programs utilize structured schedules, including medical assessments, therapy, and detoxification support, to stabilize patients during their initial week of recovery. 2 sources. https://clstr.news/cluster/inpatient-drug-rehab-processes-and-first-week-expectations ### 2026-08-17: Inpatient rehabilitation program durations and recovery factors Inpatient rehab programs often run for 30, 60, or 90 days, though research suggests longer stays may improve recovery outcomes for substance use disorders. 2 sources. https://clstr.news/cluster/inpatient-rehabilitation-program-durations-and-recovery-factors --- Cite as: Inpatient substance use disorder rehabilitation processes.
