Identifying outlier patterns of inconsistent ambulance billing in Medicare.
The objective of this study was to illustrate a method that accounts for sampling variation in identifying suppliers and counties with outlying rates of a particular pattern of inconsistent billing for ambulance services to Medicare. The investigators concluded that health care fraud and abuse were frequently asserted but could be difficult to detect. They suggested that their data-driven approach may be a useful starting point for further investigation.

How to identify team-based primary care in the United States using Medicare data.
The authors assessed whether analyses using different sets of Medicare data can produce results similar to those from analyses using 100% data from an entire state in identifying primary care teams through social network analysis. They found that, depending on specific study purposes, researchers could use either 100% data from Medicare beneficiaries in randomly selected primary care services areas or data from a 20% national sample of Medicare beneficiaries to study team-based primary care in the United States.
