The largest insurer in Massachusetts, Blue Cross Blue Shield, began a new program in 2009 that combines global payments-fixed payments for the care of patient populations during a specified time period-with large potential quality bonuses for medical groups. In interviews with representatives of the participating medical groups, many of which could be considered prototype accountable care organizations, we found that most groups initially focused on two goals: building the infrastructure to help primary care providers earn quality bonuses; and managing referrals to direct patients to lower-cost settings. Groups are working to overcome numerous challenges, which include improving their data management capabilities; managing conflicting incentives in their fee-for-service contracts; and establishing cultures that emphasize teamwork, patient-centered care, and effective stewardship of medical resources. The participating medical groups are diverse in terms of size, organizational structure, and prior experience with managed care contracting. If the groups can succeed in reducing annual growth in health spending by half over the five-year contract, it could signal that even newly formed accountable care organizations can navigate a shift from fee-for-service to population-based payment models.

Communicating openly and honestly with patients and families about unexpected medical events-a policy known as full disclosureimproves outcomes for patients and providers. Although many certification and licensing organizations have declared full disclosure to be imperative, the adoption of and adherence to a full disclosure protocol is not common practice in most clinical settings. We conducted a case study of Ascension Health's implementation of a full disclosure protocol at five labor and delivery demonstration sites. Twenty-seven months after implementation, the rate of full disclosure had increased by 221 percent. Practitioners saw insurers' acceptance of the full disclosure protocol, consistent and ongoing leadership by local practitioners and hospitals, the establishment of a well-trained local investigation and disclosure team, and disclosure training for practitioners as key catalysts for change. Lessons learned from this multisite initiative can inform liability insurers and guide providers who are committed to ensuring that full disclosure becomes the only response to unexpected medical events.

Medical malpractice expenditures are mainly due to the occurrence of preventable harm with some of the highest liability rates in obstetrics. Establishing delivery system models which decrease preventable harm and malpractice risk have had varied results over the last decade. We conducted a case study of a risk reduction labor and delivery model at 5 demonstration sites. The model included standardized protocols for the most injurious events, training teams in labor and delivery emergencies, rapid reporting with cause analysis for all unplanned events, and disclosing unexpected occurrences to patients using coordinated communication and documentation. Each of the model's components required buy in from the hospital's clinical and administrative leadership, and it also required collaboration, training, and continual feedback to labor and delivery nurses, doctors, midwives, and risk managers. The case study examined the key elements in the development of the model based on interviews of all team members and document review. We also completed data analysis pre and post implementation of the new model to assess the impact on event reporting and high liability occurrence rates. After 27 months post implementation, reporting of unintended events increased significantly (43 vs 84 per 1000 births, p < .01) while high-risk malpractice events decreased significantly (14 vs 7 per 1000 births, p < .01). This decrease enabled money allotted for malpractice claims to be reallocated for the implementation of the new model at 42 additional labor and delivery sites. Due to these results, this multilevel integrated model showed promise.

The multilevel integrated practice and coordinated communication model was successfully spread and sustained. Key elements contributing to this success included developing and maintaining evidence-based guidelines, ensuring leadership buy-in and support, collecting and reporting performance measures, holding teams accountable, providing training, and ensuring transparent communication.

Although safety net providers will benefit from health insurance expansions under the Affordable Care Act, they also face significant challenges in the postreform environment. Some have embraced the concept of the accountable care organization to help improve quality and efficiency while addressing financial shortfalls. The experience of Cambridge Health Alliance (CHA) in Massachusetts, where health care reform began six years ago, provides insight into the opportunities and challenges of this approach in the safety net. CHA's strategies include care redesign, financial realignment, workforce transformation, and development of external partnerships. Early results show some improvement in access, patient experience, quality, and utilization; however, the potential efficiencies will not eliminate CHA's current operating deficit. The patient population, payer mix, service mix, cost structure, and political requirements reduce the likelihood of financial sustainability without significant changes in these factors, increased public funding, or both. Thus the future of safety net institutions, regardless of payment and care redesign success, remains at risk.

Following passage of health care reform in Massachusetts, the Cambridge Health Alliance (CHA), a public safety-net health system, began to establish an accountable care organization in an effort to continue its mission and remain financially solvent. In examining how CHA undertook its delivery system transformation, this case study explores the organization's four major strategies: establishing patient-centered medical homes, entering alternative payment arrangements with managed care organizations, launching complex care management, and establishing a partnership with a tertiary care institution. Workforce education and culture change were also core principles. Within two years, CHA had already received National Committee for Quality Assurance patient-centered medical home recognition for six of its primary care sites, and quality metrics demonstrate improvements in these sites compared with others. Moreover, utilization in one managed care organization is trending downward. Challenges persist, however, due in part to fiscal pressures created by state health care reform. OVERVIEWThe Cambridge Health Alliance (CHA) is a public safety-net health system based in Cambridge, Mass. In 2006, after the state passed its health care reform law, CHA formed an accountable care organization (ACO) to continue its mission and remain financially solvent. An ACO is an integrated health care system made up of hospitals, physicians, and other providers who share the responsibility of caring for a population of patients. The goal is to provide high-quality, coordinated care and to reduce spending by eliminating unnecessary services, with providers potentially rewarded for meeting quality and cost benchmarks. Early ACO pilots have focused on commercial and Medicare beneficiaries; few have addressed the feasibility of implementing ACOs for Medicaid beneficiaries and other vulnerable populations. Safety-net providers, from public hospitals and health systems to community health centers, must transform the way they serve their patients and communities-and do so with fewer resources and more complex patients than traditional providers. 1 This case study-based on interviews with staff, document review, and financial analysis-examines the market, policy, and organizational factors that led CHA to undertake ACO transformation; highlights key strategies, areas ofTo learn more about new publications when they become available, visit the Fund' s website and register to receive email alerts.
