Re-used pacemakers—as safe as new? A retrospective case-control study
Why the study?
Does re-used pacemaker implantation reduce complications compared to newly manufactured pacemakers in patients requiring pacemakers?
Population
200 patients requiring pacemakers, mean age 79 +/- 9 years in re-used group and 68 +/- 21 years in new group.
Comparison

Implication
Similar complication rates with re-used pacemakers do not yet support routine adoption; leaves open need for randomized trials to confirm safety.
Structured PICO
Does re-used pacemaker implantation reduce complications compared to newly manufactured pacemakers in patients requiring pacemakers?
P
Population
200 patients requiring pacemakers (n=100 receiving re-used pacemakers, n=100 receiving new pacemakers), mean age 79 +/- 9 years in re-used group and 68 +/- 21 years in new group.
I
Intervention
Re-used pacemaker implantation
C
Comparator
Newly manufactured pacemaker implantation, matched for date of implantation and mode (AAI; VVI; DDD)
O
Outcome
Complications defined as infections and signs of pacemaker malfunction and pacemaker replacement earlier than anticipated due to battery depletionsafety
Re-using pacemakers is safe and economically advantageous, with no significant difference in complications compared to new devices.
