Authors' conclusion

This study demonstrates a statistically significant association between implantation volume and complication rates across all CIED procedures, with the effect being particularly pronounced among pacemaker patients.

Study context

Population
All first inpatient cardiac implantable electronic device (CIED) implantations performed between 1 January 2010 and 31 December 2020, in hospitals across North Rhine-Westphalia
Participants
249,118 cases
Comparison
Hospital implantation volume and complication rates
