Patient-Centered Medical Home Activities Associated With Low Medicare Spending and Utilization.

PURPOSE: To identify components of the patient-centered medical home (PCMH) model of care that are associated with lower spending and utilization among Medicare beneficiaries. METHODS: Regression analyses of changes in outcomes for Medicare beneficiaries in practices that engaged in particular PCMH activities compared with beneficiaries in practices that did not. We analyzed claims for 302,719 Medicare fee-for-service beneficiaries linked to PCMH surveys completed by 394 practices in the Centers for Medicare & Medicaid Services' 8-state Multi-Payer Advanced Primary Care Practice demonstration. RESULTS: Six activities were associated with lower spending or utilization. Use of a registry to identify and remind patients due for preventive services was associated with all 4 of our outcome measures: total spending was $69.77 less per beneficiary per month (PBPM) (P = 0.00); acute-care hospital spending was $36.62 less PBPM (P = 0.00); there were 6.78 fewer hospital admissions per 1,000 beneficiaries per quarter (P1KBPQ) (P = 0.003); and 11.05 fewer emergency department (ED) visits P1KBPQ (P = 0.05). Using a patient registry for pre-visit planning and clinician reminders was associated with $29.31 lower total spending PBPM (P = 0.05). Engaging patients with chronic conditions in goal setting and action planning was associated with 4.62 fewer hospital admissions P1KBPQ (P = 0.01) and 11.53 fewer ED visits P1KBPQ (P = 0.00). Monitoring patients during hospital stays was associated with $22.06 lower hospital spending PBPM (P = 0.03). Developing referral protocols with commonly referred-to clinicians was associated with 11.62 fewer ED visits P1KBPQ (P = 0.00). Using quality improvement approaches was associated with 13.47 fewer ED visits P1KBPQ (P =0.00). CONCLUSIONS: Practices seeking to deliver more efficient care may benefit from implementing these 6 activities.

Impact of Medical Homes on Expenditures and Utilization for Beneficiaries With Behavioral Health Conditions.

OBJECTIVE: Individuals with behavioral health conditions may benefit from enhanced care management provided by a patient-centered medical home (PCMH). In late 2011 and early 2012 Medicare began participating in PCMH initiatives in eight states through the Multi-Payer Advanced Primary Care Practice (MAPCP) demonstration. This study examined how the initiatives addressed the needs of patients with behavioral health conditions and the impacts of the demonstration on expenditures and utilization for this population. METHODS: Semistructured interviews provided insight into states' approaches to improving care, and multivariate difference-in-difference regressions of Medicare and Medicaid claims data were used to model changes in utilization and expenditures, comparing Medicare and Medicaid beneficiaries with behavioral health conditions in MAPCP demonstration practices with similar beneficiaries in non-PCMH primary care practices. Utilization included inpatient admissions and emergency department visits for all causes and for behavioral health conditions and outpatient visits for behavioral health conditions. Expenditure outcomes included expenditures for all services and those with a principal diagnosis of a behavioral health condition. RESULTS: Practices reported screening more patients for behavioral health conditions, linking patients to community-based behavioral health resources, and hiring behavioral health specialists to provide care. Several states embarked on unique initiatives to improve access to behavioral health services. However, few significant associations were found between participation in the MAPCP demonstration and utilization and expenditures for behavioral health services. CONCLUSIONS: Even though PCMHs made concerted efforts to improve access to care for their patients with behavioral health conditions, few substantial changes in patterns of care were noted.

Emergency department and inpatient hospital use by Medicare beneficiaries in patient-centered medical homes.

STUDY OBJECTIVE: Patient-centered medical homes are primary care practices that focus on coordinating acute and preventive care. Such practices can obtain patient-centered medical home recognition from the National Committee for Quality Assurance. We compare growth rates for emergency department (ED) use and costs of ED visits and hospitalizations (all-cause and ambulatory-care-sensitive conditions) between patient-centered medical homes recognized in 2009 or 2010 and practices without recognition. METHODS: We studied a sample of US primary care practices and federally qualified health centers: 308 with and 1,906 without patient-centered medical home recognition, using fiscal year 2008 to 2010 Medicare fee-for-service data. We assessed average annual practice-level payments per beneficiary for ED visits and hospitalizations and rates of ED visits and hospitalizations (overall and ambulatory-care-sensitive condition) per 100 beneficiaries before and after patient-centered medical home recognition, using a difference-in-differences regression model comparing patient-centered medical homes and propensity-matched non-patient-centered medical homes. RESULTS: Comparing patient-centered medical home with non-patient-centered medical home practices, the rate of growth in ED payments per beneficiary was $54 less for 2009 patient-centered medical homes and $48 less for 2010 patient-centered medical homes relative to non-patient-centered medical home practices. The rate of growth in all-cause and ambulatory-care-sensitive condition ED visits per 100 beneficiaries was 13 and 8 visits fewer for 2009 patient-centered medical homes and 12 and 7 visits fewer for 2010 patient-centered medical homes, respectively. There was no hospitalization effect. CONCLUSION: From 2008 to 2010, outpatient ED visits increased more slowly for Medicare patients being treated by patient-centered medical home practices than comparison non-patient-centered medical homes. The reduction was in visits for both ambulatory-care-sensitive and non-ambulatory-care-sensitive conditions, suggesting that steps taken by practices to attain patient-centered medical home recognition such as improving care access may decrease some of the demand for outpatient ED care.
