Elliot Health System’s Partial Hospitalization Program (PHP) and Intensive Outpatient Program (IOP) provide individual and group-based treatment of co-occurring substance use and mental health disorders. PHP and IOP are for individuals who need care that is more intensive than individual outpatient programs but not as intensive as residential treatment.

The primary difference between IOP and PHP are the hours of operation. Patients attend IOP on Mondays, Wednesdays, and Fridays from 9:00 a.m. to 12:00 p.m. for 12 weeks. PHP patients attend the program Monday through Friday from 8:30 a.m. to 1:00 p.m. for four weeks.

Both IOP and PHP are staffed by multidisciplinary teams that include:

  • Licensed mental health and substance use clinicians
  • Psychiatric providers
  • Registered nurses
  • Case managers
  • Recovery support staff

All staff are trained in co-occurring disorders treatment skills and in appropriate evidence-based skills, such as Motivational Interviewing, Harm Reduction, and Integrated Dual Disorder Treatment. Depending on their role, staff can provide case coordination, assist participants in accessing community-based services, provide medication management, evaluate participants for medical issues, and more. The teams coordinate closely with primary care providers on a biweekly basis to ensure that all aspects of patients’ wellbeing and health are addressed appropriately.

At the beginning of the program, all participants are assessed with a variety of standardized tools, such as AUDIT/DAST, PHQ 2 or 9, the Addiction Severity Index, the Columbia Suicide Risk Assessment and the URICA (University of Rhode Island Change Assessment). Personalized plans are developed to address their substance use, mental health, and primary care needs, as well as the major social determinants of health, poverty, food scarcity, and access to reliable housing and transportation, among others. Not only do participants receive intensive individual and group treatment, but strong aftercare and family components are also provided to ensure the continuity of care and the inclusion of family and support members in the treatment process.

Individuals can self-refer to PHP and IOP or get a referral from a provider or Doorway staff.
