Association between physician teamwork and health system outcomes after coronary artery bypass grafting.
The researchers tested whether teamwork (assessed with the bipartite clustering coefficient) among multiple providers dispersed across many care locations is a determinant of surgical outcomes by examining national Medicare data from patients undergoing CABG. They found that health systems with higher teamwork levels had significantly lower 60-day rates of emergency department visit, readmission, and mortality.

Variation in Medicare expenditures for treating perioperative complications: the cost of rescue.
The researchers evaluated differences across hospitals in the costs of care for patients surviving perioperative complications after major inpatient surgery. After 4 selected inpatient operations, substantial variation was observed across hospitals regarding Medicare episode payments for patients rescued from perioperative complications. Notably, higher Medicare payments were not associated with improved clinical performance.

Comparing approaches to controlling Medicare spending.
For 3 common surgical procedures (coronary artery bypass grafting (CABG), prostatectomy, and hip replacement), the researchers compared the relative influence of procedure rates versus episode payments (among those with procedures) on total Medicare expenditures. Using complete Part A and B Medicare claims data, they found that reducing procedure rates lowers total Medicare spending substantially more than reducing episode payments.

Reliability of hospital cost profiles in inpatient surgery.
This study sought to discover whether Medicare payments for surgery can reliably compare hospital costs. It found that episode payments for inpatient surgery are a reliable measure of hospital costs for commonly performed procedures, but are less reliable for lower volume operations. These findings suggest that hospital cost profiles based on Medicare claims data may be used to benchmark efficiency, especially for more common procedures.

Surgery and Medicare shared savings program accountable care organizations.
The researchers investigated the degree to which surgeons and other specialists are participating in Medicare Shared Savings Programs, and whether such specialist integration influences accountable care organization (ACO) performance. They found that participation by surgeons and other specialists in Medicare ACO programs is highly variable. Some ACOs include many specialists who are tightly integrated with primary care physicians, while others consist solely of primary care physicians.
