AIMS Model
The AIMS model, developed at Rush University Medical Center, assesses the needs of complex patients and then provides risk-focused care coordination by master’s prepared social workers guided by a standardized protocol. The AIMS social worker assists people with the biopsychosocial and functional issues impacting their medical care plan adherence or physical condition.
The intervention follows a five step process:
The model allows for additional chronic disease self-management education as well as transitional care for people returning to the community after a hospital stay. Activities build upon evidence-based social work core competencies of engagement and assessment, resource linkage, counseling, care coordination, motivational interviewing to promote self-management, and team interaction. Patients/caregivers direct their own care by identifying personal wellness goals, building a collaborative care plan for how to reach them, and assuming primary accountability for achieving those goals with the support and coaching of the AIMS social worker.
The AIMS model was built around the concept of shared resources across multiple practices with program services provided both face-to-face and virtually by phone or electronically. AIMS social workers are employed through a central department rather than individual practices, allowing small practices to benefit from the full-time availability of an AIMS social worker even if their individual client base would not support one in some settings. In other settings, community-based organizations partner with local primary care clinics to integrate social determinants of health and leverage resources. By centralizing resources, the AIMS model can work from a strong infrastructure for supervision, peer support, and case load distribution across many social workers. AIMS social workers are housed in their parent department outside the practices, combating the barrier of limited work space in the clinic, but are available to be on site at practices as needed.
RESULTS
The AIMS model has demonstrated success at Rush University Medical Center, contributing to the designation of seven primary care practices as Level 3 Patient Centered Medical Home by the National Committee for Quality Assurance. Moreover, consumer, provider, and caregiver feedback gathered through formal evaluation indicates high satisfaction with the program, resulting in better supported, less stressed, and better informed consumers and caregivers. Providers (n=28) reported they were able to spend more appointment time on medical issues (73%), and that people seemed less distressed (82%), showed a better sense of well-being (82%), and exhibited better self-management (73%).
Early evidence suggests an impact on avoided hospitalizations, emergency department usage, and 30-day readmissions. A retrospective analysis of the AIMS model at Rush University Medical Center showed statistically-significant lower rates of admissions, 30-day readmissions, and emergency department visits for AIMS participants as compared to a similar patient population. The impact of AIMS on utilization is currently being studied more rigorously via a two-year quasi-experimental study with the support of The Commonwealth Fund; results are anticipated by spring 2018.
Care settings
The AIMS model targets ambulatory care, with applicability to both primary and specialty care. The model was first developed in a primary care setting where individual-level needs related to psychosocial issues often appear, yet physicians may not have the time or awareness of community resources to address them. After a strong reception in primary care, the model was adapted and implemented in Rush-affiliated specialty care ambulatory clinics for conditions strongly impacted by long-term services and supports, such as movement disorders including Huntington’s disease and Parkinson’s disease, neurology, epilepsy, stroke, and multiple sclerosis.
Through support from The Harry and Jeanette Weinberg Foundation, the AIMS model has been replicated at community-based organizations in new and diverse geographic areas:
- Aging Care Connections: An aging network organization that serves suburban Cook County, Illinois and provides AIMS to patients in partnership with Prairie Medical Group and with Adventist LaGrange Family Medicine Center
- Solutions for Care: Serving the Berwyn/Cicero area (Illinois) which is a largely Hispanic community
- Jewish Community Services: Serving patients in Baltimore, Maryland
- Jewish Social Service Agency: Serving patients in Montgomery County, Maryland (part of broader Washington DC / Baltimore metropolitan area), in partnership with Capital Coordinated Medicine
Patient population served
The AIMS model serves patients/caregivers at Rush University Medical Center-affiliated primary care or specialty care practice in Chicago, Illinois. The majority of patients served are Medicare, Medicaid, and dually-eligible beneficiaries, aged 18 years. Patients referred for services are those who are believed to be complex and vulnerable as a result of intersecting social and medical needs.
The population served is grounded in patient complexity research. Patient complexity is related to the lack of social supports and other factors that impact health utilization and outcomes, specifically, the amalgamation of environmental and social factors contributing to an individual’s ability to access timely care and make informed care decisions. The AIMS social worker, in collaboration with practice staff, systematically identifies, addresses, and monitors the social, functional, environmental, cultural, and psychological issues impeding medical care as they present for patients served at the designated practice.

Rush University Medical Center received a $350,000 grant from The Commonwealth Fund to assess AIMS’s impact on patients’ health services use, health outcomes, and satisfaction with health care service delivery. They also aim to identify the core aspects essential to the success of the AIMS model. This study will conclude in April 2018.
