New research: For lower costs without worse outcomes, vertically integrate healthy health systems with certain health plans

Hospital-operated Medicare Advantage plans can help streamline post-hospitalization care of discharged inpatients while cutting episode-of-care costs and maintaining good patient outcomes, according to a study conducted at Harvard and published Aug. 31 in JAMA Network Open
The conclusion swims against the tide of prior research that raised questions about the fiscal incentives and clinical wisdom of such vertical integration.
For the present study, lead author Yanlei Ma, PhD, senior author Thomas Tsai, MD, MPH, and colleagues analyzed almost 470,000 inpatient episodes involving around 2,300 MA plans, of which 332 were operated by hospitals or their parent health systems.
The team found hospital-operated MA plan enrollment was associated with less skilled nursing facility utilization, greater use of inpatient rehabilitation rates and more readmissions.
Notably, the researchers maintain that the elevated readmissions represent a “tradeoff”—one balanced by more healthy days at home, no significant differences in mortality and no differences at all in subsequent trips to emergency rooms.
Ma and colleagues suggest the patterns they observed may reflect “differences in how post-acute care recovery is managed rather than reductions in necessary care.”
Policy insights between the lines
The researchers found that, compared with beneficiaries in other MA plans, hospital-operated MA plan enrollees were older, more often male and Hispanic, less likely to be non-Hispanic Black and less likely to be dually eligible for Medicaid.
Further, hospital-operated MA plan enrollment was associated with lower spending per episode of care ($24,072 vs $24,244), with patterns “broadly consistent across medical conditions and surgical procedures.”
Ma and co-authors believe their study offers important policy insights in the context of ongoing debates about the efficiency and value of the MA program.
“Our findings show that hospital-operated MA plans incur lower care utilization while maintaining or improving patient outcomes, a pattern consistent with more efficient care delivery,” they comment.
“However, hospital-operated MA plans that deliver care at lower cost still receive the same capitated payments as less efficient MA plans, enabling them to retain a larger share of payments as profit.”
A gentle suggestion for better benchmarking
This shortcoming highlights a structural limitation of the current MA payment system, they add, under which “more efficient MA plans do not necessarily receive lower capitated payments, which are tied to fee-for-service benchmarks and, ultimately, savings to the Medicare system.”
Policymakers should consider benchmark formulas that would stand to “better align reimbursement with MA plan-specific costs and medical loss ratios rather than uniform county averages based on the fee-for-service population,” they write.
In toto, the study’s findings suggest vertical integration between health systems and MA plans “may be associated with alternative post-acute care pathways and more efficient care,” Ma and colleagues conclude, “while offering important insights for promoting high-value care with the Medicare Advantage program.”
