Why the study?

Does intraoperative defibrillation testing affect perioperative complications or costs in patients undergoing ICD insertion?

Structured PICO

Does intraoperative defibrillation testing affect perioperative complications or costs in patients undergoing ICD insertion?

Population

361 patients undergoing implantable cardioverter defibrillator (ICD) insertion (new implants or generator replacements) across 13 sites in Canada.

Intervention

Intraoperative defibrillation testing (DT)

Comparator

No intraoperative defibrillation testing

Outcome

Details of DT, reasons for not conducting DT, costs, and complications associated with DTsafety

Defibrillation testing is omitted in about one-third of ICD implants without a significant difference in perioperative complications.

No takes yet. Share an insight, caveat, or question.

May support selective omission of defibrillation testing in ICD implantation; leaves open need for randomized trials on safety and costs.

Healey et al. (2009) studied this question.
