Assessment of prevalence and cost of care cascades after routine testing during the Medicare annual wellness visit.
This observational cohort study looked at the prevalence and cost of care cascades after routine tests considered low value in fee-for-service Medicare patients from January 2013 through March 2015 who had gone for an annual wellness visit (AWV). Among the 75,275 AWV recipients identified, 18.6% received at least 1 low-value test including an ECG, urinalysis, or thyrotropin tests. Patients who were younger, White, and lived in urban, high-income areas were most likely to receive those tests. The cost-cascade was considered notable but of modest cost.

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.
