Recovery-Oriented System of Care (ROSOC)

  • Need: To serve adults in Mendocino County, California with chronic substance use disorders, mental health diagnoses, and/or complex medical conditions who frequently utilize emergency departments and jail services.
  • Intervention: A safety net organization was formed that works with medical providers and law enforcement to reduce the high cost of caring for frequent utilizers through intensive care coordination activities.
  • Results: Greater overall stability in the lives of clients, with less utilization of low-efficacy, crisis-oriented services, hospitalizations, and incarcerations.

The Recovery-Oriented System of Care (ROSOC) is a collaborative approach to intensively engage adults who have a history of frequent crisis services utilization. These individuals may have chronic substance use disorders or co-occurring disorders, as well as other complex medical conditions.

The Mendocino County AIDS/Viral Hepatitis Network (MCAVHN) is the lead agency continuing the case management delivery that began during our more formal partnership for the former Chronic Users System of Care. Formal partners from that original collaboration are still among our network of safety net organizations. These continue to include:

ROSOC receives referrals from the emergency departments, county-contracted mental health providers, jail medical services, and from other clients in the program. Individuals are interviewed to determine their interest in changing from a crisis-based approach for care to a more stable and proactive approach to provide consistent care.

Goals for ROSOC include:

  • Participants receive primary and behavioral health care
  • Engage participants in their own care
  • Improve participants’ health status, including substance use disorders, and finding the most integrated recovery programs that include concurrent treatment of mental health issues
  • Decrease overall healthcare and other community costs

ROSOC was originally the Chronic Users System of Care (CUSOC), a 2-year pilot project funded by County Medical Services Program’s (CMSP) Local Health Connections (LHC). Due to the lack of continued funding, CUSOC ended after the pilot project ran its course. MCAVHN realized the value of the continuation of the program, and adapted CUSOC into ROSOC. Delivery of case management services continued with funding from multiple private foundation grants, local support of Mendocino County Health and Human Services, and occasional asset forfeiture funds.

This video highlights the story and impact of CUSOC:

Services offered

Services are based on willingness to participate. Clients do not have to enter the program agreeing to anything but engagement with care managers. Goals are consistent with probation and other legal sanctions, as well as personal recovery goals.

  • Assessment tools to form a biopsychosocial profile of a new participant
  • Assistance in attaining housing, Social Security Disability/Supplemental Security Income, or other income if necessary
  • Frequent contact with case manager
  • Referral and guaranteed linkage to appropriate individualized services
  • Monitoring of all services
  • Support for continued access to all services
  • Collaboration with law enforcement officials to reduce recidivism and to seek alternatives to incarceration when appropriate
  • Of those who were homeless upon entry into program, 76% are permanently or stably housed.
  • Of those who were not engaged in medical care upon entry into the program, 93% are now receiving consistent primary medical care.
  • Of those who needed, but were not engaged in mental/behavioral health services, 77% are now regularly attending behavioral health therapy and/or are receiving psychiatric medications.
  • Of those who were in need of Alcohol and Other Drug (AOD) services upon entry, 76% received AOD treatment services.
  • Of those with no income at entry into services 83% have been connected to financial assistance (through public assistance, SSI/SSDI awards, and/or employment)
  • Of those who repeatedly utilized emergency medical services and/or jail services, 96% have dramatically reduced the use of crisis-oriented services and/or incarcerations (0 to 1 incidents per reporting period).

The greatest and most consistent barrier for ROSOC clients is housing. Mendocino County, particularly the inland valley portion of the county, has a significant housing shortage. Even though 95% of ROSOC participants who were once homeless have obtained a housing subsidy certificate, many are still unable to lease-up during the 120-day time limit. Missing this limit results in a loss of their subsidy, and participants must wait for a waiting list to re-open (this can take several years). Mendocino County has a pronounced lack of 1-bedroom units for single adults, so MCAVHN operates an emergency homeless shelter for ROSOC’s vulnerable and chronically homeless individuals.


In order for a program like ROSOC to work effectively, it requires a great number of partnerships and buy-in from other agencies within local communities. It was immensely important at the beginning of this collaboration that all agencies agree on the program’s goals at the outset. Because the collaboration was successful while it was funded, it was important to come up with clear funding strategies and sources that would be available when the pilot’s funding was no longer available.
