Identifying tests related to breast cancer care in claims data.
The goal of this study was to develop a method for calculating rates of testing for breast cancer recurrence in patients who have already undergone initial treatment for breast cancer. Rates were calculated from a cohort of Medicare breast cancer patients and an age-matched noncancer cohort. They calculated testing rates in the breast cancer cohort above the background rate in the noncancer population. There were similar estimates of testing prevalence and frequency in the two groups, with exception of prevalence of computed tomography (CT).

Trends in diagnostic imaging utilization among Medicare and commercially insured adults from 2003 through 2016.
This study examined trends in use of noninvasive diagnostic imaging (NDI) among commercially insured individuals compared to Medicare enrollees from 2003 through 2016. There was more of an increase among Medicare enrollees than commercially insured patients, but both showed upward trends until the early 2010’s where trends began to be flat or decline. The notable exception was for CT imaging among commercially insured patients aged 45-64 years and Medicare enrollees after 2012.

Patterns of breast magnetic resonance imaging use in community practice.
The researchers described patterns of breast MRI use in US community practice during the period 2005 through 2009. They found that the overall rate of breast MRI from 2005 through 2009 nearly tripled from 4.2 to 11.5 examinations per 1000 women, with the most rapid increase from 2005 to 2007.
