Dispersion in the hospital network of shared patients is associated with less efficient care.
The purpose of this study was to examine the level of distribution of patient-sharing networks across U.S. hospitals and its relationship with 3 measures of care delivered by hospitals that were likely to relate to coordination. The researchers utilized data from 2016 Medicare Fee-for-Service claims to measure the volume of patients that hospitals treated in common, and then calculated a measure of dispersion for each hospital. The relationship between network dispersion, Medicare spending per beneficiary, readmission rates, and emergency department (ED) throughput rates were then estimated. The study reported that hospitals with more dispersed networks had greater spending rates but not higher admission rates or slower ED processes. Among hospitals with less resources, more dispersion was associated with higher readmission rates and slower ED processes. The researchers concluded that dispersed interhospital networks create difficulties in coordinating patients who are treated at multiple hospitals, and that the structure of patient-sharing networks may be an overlooked factor that influences the delivery of care in health care organizations.

Coordination of care around surgery for colon cancer: insights from national patterns of physician encounters with Medicare beneficiaries.
This study researched the coordination of care before and after surgery for colon cancer patients using data from Medicare A and B records. There were quite a number of different combinations of care providers both preoperative and postoperative. Larger urban teaching hospitals had the most combinations in all phases.

High-value home health care for patients with heart failure: an opportunity to optimize transitions from hospital to home.
Providing home health nursing and therapy could promote recovery in vulnerable HF patients with post-hospital syndrome and potentially reduce readmissions. The authors argue that understanding the characteristics of effective post-acute HHC for patients with HF will inform best practices, optimal outcomes for cost, and ultimately high-value care.
