Volume–outcome analysis of in-hospital complications after cardiac implantable electronic device implantation: a 250 000-case study
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

- 249,118 cases
- Comparison
- Hospital implantation volume and complication rates
- Outcome
- Overall complication rate
Methodological detailsflexible generalized additive mixed model, mandatory quality assurance data
