From informal polls I’ve recently conducted of hospitalists, many are not even aware they are part of an accountable-care organization (ACO). And if they are aware, they might not be engaging in meaningful dialogue with ACO leaders about their role in these organizations. But, in the long term, ACOs will need to bring hospitalists to the table in order to be successful.
Are You Part of an ACO?
David Muhlestein, who blogs for Health Affairs, tracks the growth of ACOs around the country. He states that, as of Jan. 31, there were 428 ACOs in the U.S. (see Figure 1).1 In terms of numbers, Florida, Texas, and California lead the nation with 42, 33, and 46 ACOs, respectively. So it is likely that you are part of an ACO. If you are unsure, ask your chief medical officer or president of the medical staff.

How ACOs Work
All ACOs seek to manage a group, or population, of patients as efficiently as possible while maintaining or improving quality of care. For Medicare ACOs, the goal is to bring together hospitals and physicians in order to share savings derived from efficiencies in care. But before any savings can be shared, the Medicare ACO must demonstrate that it achieved high-quality care across four domains, totaling 33 individual quality measures. (see Table 1)
Main Flavors of ACOs
There are two types of ACOs: private ACOs and Medicare ACOs. Prior to Medicare ACOs, which were launched in January 2012, there were 150 private-sector ACOs, and this number continues to grow. Private ACOs represent a heterogeneous group in terms of reimbursement model. Some operate under shared savings programs; others use full or partial capitation, bundled payments, and/or other types of arrangements. But nearly all ACOs operate under the premise that the incentives used to make care more efficient and less costly can only be applied if measurable quality is maintained or improved. ACOs do not pay doctors or hospitals more unless high quality is demonstrated.
ACO Quality Measures and Hospitalists
Most of the 33 quality measures required by Medicare ACOs are based in ambulatory practice. These include measures related to blood pressure, immunizations, cancer, and fall-risk screening, and measures for diabetics, such as lipids and hemoglobin A1C. However, there are a few measures for which hospitalists should share in accountability, including:
- All-cause hospital readmission rate—risk-standardized;
- Ambulatory sensitive condition hospital admission rates (CHF, COPD); and
- Medication reconciliation after discharge from an inpatient facility.
Four Key Actions for Hospitalists
Hospitalists make a significant contribution to the quality and the financial performance of ACOs. In addition to the quality metrics cited above, hospitalists impact the inpatient portion of the overall population’s cost of care. Furthermore, hospitalists are vital partners in the care coordination required for an ACO to be successful.
Here are four actions I suggest taking in order for your hospitalist group to be effective as participants in an ACO:
- Have a representative from your group participate in ACO committees that address hospital utilization and related matters, such as care coordination impacting pre- and post-hospital care.
- Learn how to work with ACO case managers on care transitions, including post-discharge follow-up and information transfer.
- Understand an ACO’s approach to engagement of and coordination with post-acute-care facilities. The ability of a post-acute facility, such a skilled nursing facility, to accept patients who have complex care needs, to manage changes in condition in the facility when appropriate, and to send complete information upon transfer to the hospital are important strategies for an ACO’s success.
- Understand how an ACO reports quality and cost performance and how savings will be shared among participants.
