| Intervention by time periods | Hospitalizations estimate, IRR (SE) | p-value | Emergency department visits estimate, IRR (SE) | p-value |
|---|---|---|---|---|
| 12 months | ||||
| Preintervention | Reference | Reference | ||
| Postintervention | 0.82 (0.73–0.91) | 0.006 | 0.67 (0.51–0.87) | 0.003 |
| 6 months | ||||
| Preintervention | Reference | Reference | ||
| Postintervention, 0–180 days | 0.92 (0.86–0.96) | 0.023 | 0.88 (0.80–0.96) | 0.009 |
| Postintervention, 181–365 days | 0.79 (0.74–0.85) | <0.001 | 0.36 (0.25–0.51) | <0.001 |
Note: Models were adjusted for age, gender, partner network/medical group, comorbidities, risk score, and baseline utilization 1 year before intervention. Difference in differences is presented as the interaction between time periods with the intervention group.
Abbreviations: IRR, adjusted incident rate ratio; SE, standard error.
