As providers, policymakers and advocates navigate myriad approaches to addressing high healthcare costs and uneven quality in America, special attention to meeting the needs of complex patients is warranted. The care these patients receive is often fragmented and not tailored to address their unique social and medical needs.
Innovative models have been adopted around the country that employ new care approaches to address unmet social and medical needs. These approaches can result in lower healthcare costs, improved quality and may reduce disparities. Realizing these benefits can be challenging—program directors must surmount financing silos, adopt new data systems and tailor the right model to the right population. Nonetheless, these models deserve a careful look.
Complex patients account for a large portion of healthcare spending in the U.S. The costliest one percent of patients account for 20 percent of healthcare spending and the costliest five percent account for 50 percent.1
Excellent work by the Commonwealth Fund2 and others reveals that complex patients are a very diverse group, including:
This patient group lacks a precise taxonomy. Complex patients are also referred to as super utilizers and high-cost, high-need patients.
The Agency for Healthcare Research and Quality defines complexity as the “magnitude of mismatch between a patient’s needs and the services available to him/her in the healthcare system and community.”3 The Centers for Medicare & Medicaid Services defines these patients as those with “complex, unaddressed health issues and a history of frequent encounters with healthcare providers.”4 Research done by The Commonwealth Fund defines complex patients as those with three or more chronic conditions and a functional limitation.5
What’s critically important for realizing the gains from the social-medical care models described below is to understand the diversity within these patients and to tailor the model to meet their needs. For example:
Fortunately new models of care are showing success for these costly, yet under-served patients. Clear evidence is emerging that the integration of clinical care and behavioral healthcare and the services of community-based organizations can consistently improve the quality of care and deliver better health outcomes for our most complex patients. As described above, complex patients have a diversity of needs. Successful care models identify complex patients and address their specific needs.
Addressing Unmet Medical Needs
There are various reasons for why complex patients suffer from poor outcomes, but research points predominantly to poor care coordination. While patients self-report comparatively low rates of unmet medical needs, researchers generally believe this a much more prevalent issue.20
Many patients with complex medical needs also have behavioral health and substance abuse needs. Like other complex patients, this subpopulation sees multiple providers and communication difficulties can lead to poor coordination of care. An estimated 70 percent of adults with a mental health issue also have a physical condition that needs to be treated by a physician.21 Patients are often referred by their primary care physician to another doctor or practice to meet the needs of their behavioral health condition. This creates a chasm in the continuum of care if there is a coordination breakdown between providers.
Patients with mental health diagnoses use more medical resources and are admitted to the hospital more frequently than patients from the general population. A study conducted by The Commonwealth Fund found that complex patients with behavioral health conditions have a greater likelihood of remaining high spenders over two years than those without such conditions.22
Improved care coordination will reflect:
Addressing Unmet Social Needs
Compelling research finds that social determinants of health have a greater influence on outcomes than medical factors.24 Unfortunately, as a nation, we spend far less on social services than other countries. Generally, unmet social needs are associated with higher rates of emergency department use, hospital admissions and readmissions.25A key feature of tailoring better models of care for complex patients must address their unmet social needs:
When these patients have significant social needs, partnering at the community level is of critical importance to improve their health outcomes. Successful interventions often feature social service investments and partnerships between healthcare and social services, for example, housing supports, nutrition assistance, case management and community outreach.27
Meeting social needs is often hard to do. Data is often missing to identify those needs, providers may not have avenues for addressing social needs, community needs may be lacking and financing structures oftentimes do not reimburse for needs assessment or social services.28
Nonetheless, myriad models around the country have found ways to create successful medical-social partnerships. Common attributes of successful models include:29
Using Data to Target At-Risk Populations—Hot Spotting
It is critically important to identify patterns that exist in the population and target these care models correctly. Through “hotspotting,” claims data and a variety of other data sources, we can begin to strategically implement targeted interventions to address a community’s problems. The Camden Coalition is an example of a successful model that works to gather real-time data through a multi-hospital collaborative. The data collected is used to identify “super utilizers” and then work across a spectrum of care providers, including those outside of traditional medical treatments, such as food access or housing, to provide care.
Community Health Workers
There is strong evidence that community health workers (CHW) within can help reduce disparities, improve quality of care and reduce costs. Community health workers are already embedded within communities and have a deep understanding of the population they serve. CHWs can leverage this information to effectively bridge the divide between the healthcare provider and the day-to-day life of a patient outside the hospital walls. The responsibilities of a CHW may vary, but compared to physicians or other healthcare workers, they are well situated to help complex patients navigate the health system and access the community’s non-medical resources. Use of CHWs is growing. According to a recent estimate, there were 48,000 working in the U.S in 2015, an increase of 27 percent from three years earlier.31 Evidence shows that the use of CHWs can help effectively manage chronic care conditions that result in higher usage of the emergency department.32
Community Care of North Carolina
Community Care of North Carolina is a partnership between the state and 14 nonprofit community care networks located in different areas across the state.33 The network has local providers that deliver components of a patient-centered medical home for low-income adults on Medicaid and children on the State Children’s Health Insurance Plan. CCNC is funded both publicly and privately through the North Carolina Department of Health and Human Services and the North Carolina Division of Medical Assistance. The program has delivered very high cost saving results resulting from decreased readmission and ED utilization. Since the program has 14 networks located across the state, it allows the program to assess its own needs at a local level allowing them to continually reevaluate the needs of their population and each network has its own separate composition. The program has delivered very promising results for patients with chronic conditions. The program has also paired up with The Commonwealth Fund to create a toolkit that other states use to better address low-income patients in their states.
ECHO Care Complex Care Program
Project ECHO began with a grant from the Center for Medicare and Medicaid Innovation to target complex patients in New Mexico, mainly a population that has a combination of behavioral health conditions, poverty or homelessness.34 The program relies on telemedicine sessions and community health workers to allow clinicians to reach patients that live in rural areas. Results have been promising - hospitalizations fell by 27 percent and emergency department visits have decreased by 32 percent.35
GRACE—Geriatric Resources for Assessment and Care of Elders
The GRACE model is an integrated care model featuring an interdisciplinary geriatrics team. Nurse practitioners and social workers assess patients in their home and develop care management plans based on their findings. Plans are presented to the full care-management team, whose members prioritize interventions and generate patient reports. The GRACE model targets low-income seniors, many of whom are dually eligible with multiple chronic conditions. In a two-year randomized controlled trial, GRACE was cost neutral during the first year, due to program costs. But in the second year, there was a clear net savings of $1,500 per patient due to reduced hospitalizations.36
Hennepin Health Model
The Hennepin Health Model is a collaboration between Hennepin County and the Minnesota Department of Human Services. The partnering agencies work together to address the social determinants of health for defined populations. They coordinate efforts to address members’ medical, behavioral, and social problems through a network of providers and partnering social service agencies. Hennepin Health’s approach is to focus first on stabilizing members’ lives, then encourage them to take medications, to try counseling and addiction treatments, and to seek care for their neglected medical problems. During the first year the program resulted in a 9 percent drop in emergency department visits and a 3.2 percent reduction in inpatient hospital admissions.37
Implementing these models of care broadly, yet still tailored to the needs of the patient, will prove challenging. Yet, it is a core responsibility of advocates and policymakers to look past current financing and practice silos to comprehensively address the needs of these patients across programs and across time.
To that end, we recommend:
Complex patients have multiple chronic conditions and often struggle to manage them. They may have functional limitations, or a combination of vulnerabilities including social disadvantages such as homelessness, low income, behavioral health issues, which are likely to have a disparate impact on racial and ethnic minorities.
Because this is a very high-cost population that often experiences unmet social needs and care coordination failures, there is tremendous opportunity to improve the lives of these patients and likely reduce net social and health spending. Models of care that are data driven, tailored to the patient population and integrate healthcare and social service providers are extremely promising and deserve the sustained attention of policymakers and advocates. Implementing new models of care could lead to great progress in achieving our triple goal of reducing cost, improving quality of care, and reducing disparities.
