Table 5.
Models of association between HRR and evidence-based ICD use with various adjustments for network centrality and network other measures.
| Estimate | Std. err. | p-value | |
|---|---|---|---|
| HRR (South Bend) without adjusting for network measures | −1.09 | 0.306 | <0.0001 |
| Estimate | Std. err. | p-value | |
|---|---|---|---|
| HRR (South Bend) | −0.677 | 0.494 | 0.171 |
| Physician node strength | 0.005 | 0.003 | 0.050 |
| Physician weighted closeness centrality | 0.157 | 0.264 | 0.551 |
| Hospital weighted closeness centrality | 0.384 | 0.286 | 0.178 |
| Estimate | Std. err. | p-value | |
|---|---|---|---|
| HRR (South Bend) | −0.825 | 0.618 | 0.182 |
| Physician node strength | 0.005 | 0.003 | 0.096 |
| Physician weighted closeness centrality | 0.136 | 0.307 | 0.656 |
| Hospital weighted closeness centrality | 0.637 | 0.713 | 0.372 |
| Family practice homophily | −0.252 | 0.410 | 0.539 |
Note: The model estimates, standard errors (std. err.) and p-values for models adjusting only for patient characteristics (top), and then also for physician and hospital centrality (middle) and physician and hospital centrality and family practice homophily (bottom) are shown.
