Why the study?

Defibrillation testing can cause complications and omitting it has been shown to be safe, prompting evaluation of its contemporary temporal trends and practice variation in the United States.

Population

499 211 patients undergoing first-time ICD implantation from 1794 facilities

Comparison

Defibrillation testing vs no defibrillation testing

Design

Multicenter cross-sectional study

Discussion

Member takes

Implication

DFT use declined markedly with substantial hospital variation; leaves open optimal testing thresholds and need for updated randomized guidance.

Structured PICO

Population

499,211 patients from 1,794 facilities undergoing first-time implantable cardioverter-defibrillator (ICD) implantation from April 2010 to December 2015 in the United States. Mean age 65.5 years, 71.4% men.

Intervention

Defibrillation testing (DFT) during ICD implantation

Comparator

No defibrillation testing

Outcome

Defibrillation testing rates and median odds ratios (MORs) over time
