Physician network position and patient outcomes following implantable cardioverter defibrillator therapy.

ABSTRACT:

Objective

To evaluate two novel measures of physician network centrality and their associations with implantable cardioverter defibrillator (ICD) procedure volume and health outcomes.

Data sources

Medicare claims and the National Cardiovascular Data Registry data from 2007 to 2011.

Study design

We constructed a national cardiovascular disease patient-sharing physician network and used network analysis to characterize physician network centrality with two measures: within-hospital degree centrality (number of connections within a hospital) and across-hospital degree centrality (number of connections across hospitals). The primary outcome was risk-adjusted 2-year case fatality. Hierarchical logistic regression estimated the effects of physician's within-hospital and acr
