Brief Summary:
The goal of the pilot study is to compare whether a centre-wide policy of incremental antibiotic therapy will reduce pacemaker infection compared to a policy of conventional antibiotic prophylaxis in high-risk patients undergoing arrhythmia device procedures. This pilot study will provide feasibility information for a larger cluster randomized crossover design (CRCD).

Condition or disease Intervention/treatment Phase
Arrhythmia Drug: Incremental Drug: Cefazolin Phase 4

Detailed Description:
Multi-center, cluster crossover, unblinded, pilot study. Centers will be randomized to conventional vs. incremental antibiotic therapy for 2 months or until eligible 20 patients are treated, whichever comes first. At 2 months, centers will have a crossover period of 4 weeks where the alternate strategy is implemented, followed by the final 2-month/20 patient enrolment period. During each treatment period the randomized antibiotic strategy will be used on all center patients undergoing a device implant procedure. Prior to the planned surgery or at the first follow up visit, patients who meet the study eligibility criteria will be approached to obtain consent for data collection purposes. Follow up will be according to usual clinical care at the center.
