Postdischarge monitoring using interactive voice response system reduces 30-day readmission rates in a case-managed Medicare population.

BACKGROUND: Automated home monitoring systems have been used to coordinate care to improve patient outcomes and reduce rehospitalizations, but with little formal study of efficacy. The Geisinger Monitoring Program (GMP) interactive voice response protocol is a post-hospital discharge telemonitoring system used as an adjunct to existing case management in a primary care Medicare population to reduce emergency department visits and hospital readmissions. OBJECTIVES: To determine if use of GMP reduced 30-day hospital readmission rates among case-managed patients. RESEARCH DESIGN: A pre-post parallel quasi-experimental study. METHODS: A total of 875 Medicare patients who were enrolled in the combined case-management and GMP program were compared with 2420 matched control patients who were only case managed. Claims data were used to document an acute care admission followed by a readmission within 30 days in the preintervention and postintervention periods (ie, before and during 2009). Regression modeling was used to estimate the within-patient effect of the intervention on readmission rates. RESULTS: The use of GMP with case management was associated with a 44% reduction in 30-day readmissions in the study cohort (95% confidence interval, 23%-60%, P=0.0004), when using the control group to control for secular trends. Similar estimates were obtained when using different propensity score adjustment methods or different approaches to handling dropout observations. CONCLUSIONS: Investing in automated monitoring systems may reduce hospital readmission rates among primary care case-managed patients. Evidence from this quasi-experimental study demonstrates that the combination of telemonitoring and case management, as compared with case management alone, may significantly reduce readmissions in a Medicare Advantage population.

The value of value-based insurance design: savings from eliminating drug co-payments.

OBJECTIVES: To estimate the cost impact of a $0 co-pay prescription drug program implemented by a large healthcare employer as a part of its employee wellness program. STUDY DESIGN: A $0 co-pay program that included approximately 200 antihypertensive, antidiabetic, and antilipid medications was offered to Geisinger Health System (GHS) employees covered by Geisinger Health Plan (GHP) in 2007. Claims data from GHP for the years 2005 to 2011 were obtained. The sample was restricted to continuously enrolled members with Geisinger primary care providers throughout the study period. METHODS: The intervention group, defined as 2251 GHS employees receiving any of the drugs eligible for $0 co-pay, was propensity score matched based on 2 years of pre-intervention claims data to a comparison group, which was defined as 3857 non-GHS employees receiving the same eligible drugs at the same time. Generalized linear models were used to estimate differences in terms of per-member-per-month (PMPM) claims amounts related to prescription drugs and medical care. RESULTS: Total healthcare spending (medical plus prescription drug spending) among the GHS employees was lower by $144 PMPM (13%; 95% CI, $38-$250) during the months when they were taking any of the eligible drugs. Considering the drug acquisition cost and the forgone co-pay, the estimated return on investment over a 5-year period was 1.8. CONCLUSIONS: This finding suggests that VBID implementation within the context of a wider employee wellness program targeting the appropriate population can potentially lead to positive cost savings.

Reduced acute inpatient care was largest savings component of Geisinger Health System's patient-centered medical home.

Early evidence suggests that the patient-centered medical home has the potential to improve patient outcomes while reducing the cost of care. However, it is unclear how this care model achieves such desirable results, particularly its impact on cost. We estimated cost savings associated with Geisinger Health System's patient-centered medical home clinics by examining longitudinal clinic-level claims data from elderly Medicare patients attending the clinics over a ninety-month period (2006 through the first half of 2013). We also used these data to deconstruct savings into its main components (inpatient, outpatient, professional, and prescription drugs). During this period, total costs associated with patient-centered medical home exposure declined by approximately 7.9 percent; the largest source of this savings was acute inpatient care ($34, or 19 percent savings per member per month), which accounts for about 64 percent of the total estimated savings. This finding is further supported by the fact that longer exposure was also associated with lower acute inpatient admission rates. The results of this study suggest that patient-centered medical homes can lead to sustainable, long-term improvements in patient health outcomes and the cost of care.

Impact of a value-based insurance design for back pain on health plan member satisfaction and its implications for patient outcomes.

Back pain is one of the most common reasons for seeking care, and physical therapy (PT) can be an effective treatment option. However, PT coverage for back pain varies widely among private health plans, usually requiring high cost sharing, thereby potentially leading to member dissatisfaction and worse outcomes. In this study, a quasi-experimental design was used to estimate the impact of a new value-based insurance design for back pain-related PT on selected Consumer Assessment of Healthcare Providers and Systems survey items. Under this design, eligible members receive a bundle of 5 PT sessions for a 1-time co-payment; if deemed necessary, the bundle is renewable for 1 additional co-payment. The results indicate that the proportion of members reporting the highest satisfaction rating was higher by about 6 to 10 percentage points among those who received the PT bundle. The data also indicate that those PT bundle members who reported the highest satisfaction rating had improvements in their functional status scores that were roughly 3 to 4 times higher than those who reported a lower satisfaction rating. These findings suggest that providing a value-based insurance design for back pain-related PT can potentially improve health plan members' care experiences and their overall satisfaction. Further study is needed to determine its impact on back pain-related medical care utilization and cost of care.

Primary care diabetes bundle management: 3-year outcomes for microvascular and macrovascular events.

OBJECTIVES: To determine whether a system of care with an all-or-none bundled measure for primary-care management of diabetes mellitus reduced the risk of microvascular and macrovascular complications compared with usual care. STUDY DESIGN: A parallel pre-post observational design was used. In 2006, a system of care for diabetes was implemented for some members of the Geisinger Health Plan. A total of 4095 primary-care patients were in the Diabetes System of Care group (DS) and compared with a propensity score-matched cohort of 4095 primary care patients not in the system of care (non-Diabetes System of Care [NDS]). METHODS: Cumulative hazard rate was measured over a 3-year period for retinopathy, amputation, stroke, and myocardial infarction (MI). RESULTS: The adjusted hazard ratios (HRs) for MI (HR, 0.77; 95% CI, 0.65- 0.90), stroke (HR, 0.79; CI, 0.65-0.97), and retinopathy (HR, 0.81; CI, 0.68-0.97) were all significantly lower among DS patients. The adjusted HR for major amputations (HR, 1.32; CI, 0.45-3.85) did not differ between groups, but only 17 major amputations occurred during the follow-up period. The necessary number of patients to treat in order to prevent 1 event over 3 years was 82 for MI, 178 for stroke, and 151 for retinopathy. CONCLUSIONS: A system of care with an all-or-none bundled measure used in primary care for patients with diabetes may reduce the risk of MI, stroke, and retinopathy over a 3-year period.

Improving patient experience by transforming primary care: evidence from Geisinger's patient-centered medical homes.

Patient-centered medical homes (PCMHs) have the potential to improve patient experience of care. Since 2006, Geisinger Health System has implemented its own version of an advanced PCMH model, referred to as ProvenHealth Navigator (PHN). To evaluate the impact of PHN on patient experience of care, the authors conducted a survey of patients whose primary care clinics had been transformed to "PHN sites" and were under case management at the time of the survey. A comparable survey of patients from non-PHN sites also was conducted for comparison. The results suggest that patients in PHN sites were significantly more likely to report positive changes in their care experience and quality; moreover, they were more likely to cite the physician's office as their usual source of care rather than the emergency room (83% vs. 68% for physician's office; 11% vs. 23% for emergency room). However, the results also suggest that there was no significant difference between PHN and non-PHN patients in their perceptions of access to care or primary care physician performance in terms of patient-centered care (eg, listening, explaining, involving patients in decision making). These findings are consistent with the expectation that transformation of primary care into PCMH can lead to improved patient experience of care.

Value-based reengineering: twenty-first century chronic care models.

The need for improved models of chronic care is great and will become critical over the next years as the Medicare-aged population doubles. Many promising models have been developed by outstanding groups across the country. This article reviews key strategies used by successful models in chronic disease management and discusses in detail how Geisinger has evolved and organized its cohesive delivery model.

Can a patient-centered medical home lead to better patient outcomes? The quality implications of Geisinger's ProvenHealth Navigator.

One of the primary goals of the patient-centered medical home (PCMH) is to provide higher quality care that leads to better patient outcomes. Currently, there is only limited evidence regarding the ability of PCMHs to achieve this goal. This article demonstrates the effect of PCMHs in improving certain clinical outcomes, as shown by the ProvenHealth Navigator (PHN), an advanced PCMH model developed and implemented by Geisinger Health System. In this study, the authors examined the claims data from Geisinger Health Plan between 2005 and 2009 and estimated the effect of PHN on reducing amputation rates among patients with diabetes, end-stage renal disease, myocardial infarction, and stroke. The results show that, despite its relatively short period of existence, PHN has led to significant improvements in certain outcomes, further illustrating its potential as a care delivery model to be adopted on a wider scale.

Reducing long-term cost by transforming primary care: evidence from Geisinger's medical home model.

OBJECTIVES: To estimate cost savings associated with ProvenHealth Navigator (PHN), which is an advanced model of patient-centered medical homes (PCMHs) developed by Geisinger Health System, and determine whether those savings increase over time. STUDY DESIGN: A retrospective claims data analysis of 43 primary care clinics that were converted into PHN sites between 2006 and 2010. The study population included Geisinger Health Plan's Medicare Advantage plan enrollees who were 65 years or older treated in these clinics (26,303 unique members). METHODS: Two patient-level multivariate regression models (with and without interaction effects between prescription drug coverage and PHN exposure) with member fixed effects were used to estimate the effect of members' exposure to PHN on per-member per-month total cost, controlling for member risk, seasonality, yearly trend, and a set of baseline clinic characteristics. RESULTS: In both models, a longer period of PHN exposure was significantly associated with a lower total cost. The total cumulative cost savings over the study period was 7.1% (95% confi dence interval [CI] 2.6-11.6) using the model with the prescription drug coverage interaction effects and 4.3% (95% CI 0.4-8.3) using the model without the interaction effects. Corresponding return on investment was 1.7 (95% CI 0.3-3.0) and 1.0 (95% Cl -0.1 to 2.0), respectively. CONCLUSIONS: Our finding suggests that PCMHs can lead to significant and sustainable cost savings over time.

How Geisinger's advanced medical home model argues the case for rapid-cycle innovation.

The Patient Protection and Affordable Care Act of 2010 provides for a number of major payment and delivery system initiatives. These potential changes need to be tested, scaled, and adapted with an urgency not evident in previous demonstration projects of the Centers for Medicare and Medicaid Services. We discuss lessons learned from our iterative tests of care reengineering at Geisinger--specifically, through our advanced medical home model, ProvenHealth Navigator, and the way we continuously modified the model to improve quality and value. We hypothesize that the most important ingredient in our model has been the embedding of nurse case managers into our community practices and the real-time feedback of data on the use of health services by the most complex patients.

Value and the medical home: effects of transformed primary care.

BACKGROUND: The primary care medical home has been promoted to integrate and improve patient care while reducing healthcare spending, but with little formal study of the model or evidence of its efficacy. ProvenHealth Navigator (PHN), an intensive multidimensional medical home model that addresses care delivery and financing, was introduced into 11 different primary care practices. The goals were to improve the quality, efficiency, and patient experience of care. OBJECTIVE: To evaluate the ability of a medical home model to improve the efficiency of care for Medicare beneficiaries. STUDY DESIGN: Observational study using regression modeling based on preintervention and postintervention data and a propensity-selected control cohort. METHODS: Four years of claims data for Medicare patients at 11 intervention sites and 75 control groups were analyzed to compute hospital admission and readmission rates, and the total cost of care. Regression modeling was used to establish predicted rates and costs in the absence of the intervention. Actual results were compared with predicted results to compute changes attributable to the PHN model. RESULTS: ProvenHealth Navigator was associated with an 18% (P <.01) cumulative reduction in inpatient admissions and a 36% (P = .02) cumulative reduction in readmissions across the total population over the study period. CONCLUSIONS: Investing in the capabilities of primary care practices to serve as medical homes may increase healthcare value by improving the efficiency of care. This study demonstrates that the PHN model is capable of significantly reducing admissions and readmissions for Medicare Advantage members.

"ProvenCareSM": a provider-driven pay-for-performance program for acute episodic cardiac surgical care.

OBJECTIVE: To test whether an integrated delivery system could successfully implement an evidence-based pay-for-performance program for coronary artery bypass graft (CABG) surgery. METHODS: The program consisted of 3 components: (1) establishing implementable best practices; (2) developing risk-based pricing; (3) establishing a mechanism for patient engagement. Surgeons reviewed all class I and IIa "2004 American Heart Association/American College of Cardiology Guidelines for CABG Surgery" and translated them into 40 verifiable behaviors. These were imbedded within a new ProvenCareSM program and "hardwired" within the electronic health record system, including order sets, templates, and "time outs". Concurrently preoperative, inpatient, and postoperative care within 90 days was packaged into a fixed price. A Patient Compact was developed to highlight the importance of patient activation. All elective CABG patients treated between February 2, 2006 and February 2, 2007 were included (ProvenCareSM Group) and compared with 137 patients treated in 2005 (Conventional Care Group). RESULTS: Initially, only 59% of patients received all 40 best practice components. At 3 months, program compliance reached 100%, but fell transiently to 86% over the next 3 months. Reliability subsequently increased to 100% and was sustained for the remainder of the study period. The overall trend in reliability was significant at P=0.001. Thirty-day clinical outcomes showed improved trends () but only the likelihood of discharge to home reached statistical significance. Length of stay decreased by 16% and mean hospital charges fell 5.2%.(Table is included in full-text article.) CONCLUSION: A provider-driven pay-for-performance process for CABG, enabled by an electronic health record system, can reliably deliver evidence-based care, fundamentally alter reimbursement incentives, and may ultimately improve outcomes and reduce resource use.
