New real-world evidence.
Comparative effectiveness of ambulatory monitors for arrhythmia diagnosis (CAMELOT).

The first and largest study of its kind found Zio XT monitoring is associated with the highest diagnostic yield and lowest likelihood of retesting.1,2

Compared with all other monitoring services, Zio XT was associated with:

HIGHEST DIAGNOSTIC YIELD, LOWEST RETEST LIKELIHOOD LOWEST HEALTHCARE, RESOURCE UTILIZATION

Study design and methodology

The claims represent the coding that providers used to document the care they provided to their patients and the follow-up paths those same patients followed. The only claims included in the analysis were for patients who had not had previous cardiac monitoring, resulting in a balanced and comprehensive comparison of retest and healthcare resource utilization.

The study cohort of 287,789 diagnostic-naïve patients was derived from the full Medicare fee-for-service data set of 1,582,784.

The first and largest retrospective claims analysis using Medicare fee-for-service documentation.1,2

The cohort included 287,789 patients.
