Drivers of High-cost Medical Complexity in a Medicaid Population.

BACKGROUND: Efforts to improve outcomes for the 10% of patients using two thirds of health care expenditures increasingly include addressing social determinants. Empiric evidence is needed to identify the highest impact nonmedical drivers of medical complexity and cost. OBJECTIVES: This study examines whether complex, highest cost patients have different patterns of critical life adversity than those with better health and lower utilization. RESEARCH DESIGN: Using a validated algorithm we constructed a complexity/cost risk patient profile. We developed and fielded a life experience survey (Supplemental Digital Content 1, http://links.lww.com/MLR/B920) to a representative sample, then examined how the prevalence of specific adversities varied between complex, high-cost individuals, and others. SUBJECTS: Surveys were sent to 9176 adult Medicaid members in Portland, Oregon. MEASURES: Our primary variable was high medical complexity health cost risk; an alternative specification combined health cost risk and actual utilization/cost. Our survey instrument measured exposure to early and later-life adversities. RESULTS: Compared with healthy individuals in our population, medically complex individuals had significantly higher rates of adversity. The greatest risk of medical complexity and cost was associated with substance use [odds ratio (OR), 4.1], homelessness (OR, 3.0), childhood maltreatment (OR, 2.8), and incarceration (OR 2.4). Those with the highest prior year acute care utilization and cost had the highest rates of these same factors: substance use (62.5%), homelessness (61.7%), childhood maltreatment (55.5%), and incarceration (52.1%). CONCLUSION: Clinical and policy strategies that mitigate high-impact social drivers of poor outcomes are likely critical for improving both health and costs for complex, high-needs patients.

Using health-related quality of life assessments to evaluate care support within Medicaid.

CareOregon, an Oregon-based not-for-profit Medicaid health plan, successfully piloted a "CareSupport" model that identifies high-risk members and clinically stratifies them for intervention. Internal analyses indicate that CareSupport lowers utilization and cost; CareOregon, however, has lacked patient-reported outcome data on the health-related quality of life (HRQL) of CareSupport participants. Between September 2005 and November 2006, we conducted a pilot study in which the Health Utilities Index Mark 3 (HUI3), a generic preference-based measure of health status and HRQL, was integrated into CareOregon's existing screening algorithm for possible admission into CareSupport. We obtained baseline data on 616 CareSupport candidates and 4-month HUI3 follow-up data on 143 candidates (104 CareSupport 39 non-CareSupport). On a 0.00 (dead)-to-1.00 (perfect health) scale, the mean overall baseline HUI3 score for CareSupport patients was 0.18 (0.20 for non-CareSupport patients), comparable to baseline means reported elsewhere for much older patients immediately after suffering serious acute medical events, such as stroke or hip fracture. A 0.05 mean 4-month improvement in overall HRQL among CareSupport enrollees relative to non-CareSupport enrollees was clinically important but not statistically significant. A 0.10 improvement in HUI3 emotion was both statistically significant and clinically important. Study results provide good preliminary evidence of the value of patient-reported outcomes in clarifying individual illness burden and assessing intervention effectiveness.

Post-discharge intervention in vulnerable, chronically ill patients.

BACKGROUND: Studies suggest that the inpatient to outpatient transition of care is a vulnerable period for patients, and socioeconomically disadvantaged populations may be particularly susceptible. OBJECTIVE: In this prospective cohort study, clustered by hospital, we sought to determine the feasibility and utility of a simple, post-discharge intervention in reducing hospital readmissions. METHODS: Chronically ill Medicaid managed care members were consecutively identified from the discharge records of 10 area hospitals. For patients from the 7 intervention hospitals, trained medical assistants performed a brief telephone needs assessment, within 1 week of discharge, in which issues requiring near-term resolution were identified and addressed. Patients with more complicated care needs were identified according to a 4-domain care needs framework and enrolled in more intensive care management. Patients discharged from the 3 control hospitals received usual care. We used a generalized estimating equation model, which adjusts for clustering by hospital, to evaluate the primary outcome of hospital readmission within 60 days. RESULTS: There were 97 intervention and 130 control patients. Intervention patients were slightly younger and had higher adjusted clinical group (ACG) scores. In unadjusted analysis, the intervention group had lower, but statistically similar, 60-day rehospitalization rates (23.7% vs 29.2%, P = 0.35). This difference became significant after controlling for ACG score, prior inpatient utilization, and age: adjusted odds ratio (OR) [95% confidence interval (CI)] 0.49 [0.24-1.00]. CONCLUSIONS: A simple post-discharge intervention and needs assessment may be associated with reduced recurrent hospitalization rates in a cohort of chronically ill Medicaid managed care patients with diverse care needs.

An alternative to pay-for-performance: one health plan's approach to quality improvement.

To address concerns about the quality of care, health plans have used varying approaches to support quality improvement (QI). Pay-for-performance (P4P) is the most commonly used and discussed approach. P4P programs have many challenges in design and execution, particularly for Medicaid providers. In order to find an alternative to P4P, CareOregon--a nonprofit health plan serving Medicaid and Medicare enrollees--developed the Care Support and System Innovation (CSSI) Program. An evaluation was conducted to assess the overall affect of the CSSI Program in promoting comprehensive improvements in quality of care and the extent to which it has the potential to offer a viable alternative to P4P. The evaluation found that the CSSI Program successfully addressed many challenges inherent in P4P. The CSSI Program engaged providers, fostered a culture of QI within CareOregon's network, and provided practices with the opportunity to develop sustainable and innovative solutions to address quality concerns. Success of the program was attributed to CareOregon's focus on building relationships while providing technical assistance and responsive funding. While health outcome data were not available to assess impact on CareOregon's members, evaluation findings highlight the importance of collaboration in QI efforts, and suggest that the model has the potential to overcome many of the challenges faced by P4P.

The economics of depression in primary care: de-fragmentation in the Oregon Medicaid market.

The Oregon Medicaid program legislatively separates the administration of physical health and mental health services, even though behavioral and physical health conditions significantly impact each other. To overcome this barrier and enhance integrated care, CareOregon, a large Medicaid only health plan partnered with two of its largest provider groups to pilot two different models of integration. In one, an "ownership" model, behavioral health specialists were employed by Federally Qualified Health Center primary care clinics and functioned in a common care model with other providers. In the other, a "loaned" model, behavioral specialists were placed in primary care clinics by community mental health centers and continued to function in a specialty mental health model. The qualitative effects of these two models are discussed.
