Why the study?

Does increasing ICD battery longevity reduce the need for device replacements and associated costs in patients with ICDs?

Population

164 veterans with 301 ICD implants between June 1992 and April 2007, deceased as of April 2009

Comparison

Prolongation of ICD battery life vs Actual observed ICD battery longevity

Design

Cohort

Follow-up

Up to 15 years

Implication

Longer ICD batteries may reduce replacements and costs; leaves open prospective confirmation of modeled savings.

Structured PICO

Does increasing ICD battery longevity reduce the need for device replacements and associated costs in patients with ICDs?

P
Population
164 veterans with 301 ICD implants between June 1992 and April 2007, deceased as of April 2009
I
Intervention
Prolongation of ICD battery life (hypothetical scenarios of 5, 7, or 9 years)
C
Comparator
Actual observed ICD battery longevity
O
Outcome
Need for ICD replacements, associated costs, and risks

Prolonging ICD battery life to 7 or 9 years significantly reduces the need for device replacements, lowering patient risks and healthcare costs.
