| Outcome | IPC Group, No. (%) (n = 46,829) | Non-IPC Group, No. (%) (n = 48,499) | Risk Difference,a % (95% CI) | Relative Risk (95% CI) |
|---|---|---|---|---|
| Any ED visit | 15,398 (32.9) | 15,472 (31.9) | 1.0 (0.4-1.6) | 1.03 (1.01-1.05) |

| Potentially avoidable hospitalizationc | 624 (1.3) | 595 (1.2) | 0.1 (0.0-0.3) | 1.09 (0.97-1.22) |
ACSC = ambulatory care–sensitive condition; COPD = chronic obstructive pulmonary disease; ED = emergency department; IPC = interprofessional primary care.
Note: Sample was weighted based on propensity to be in the IPC group given age, income, residence (urban-rural spectrum), recent immigrant status, comorbidity, prior physician visits, and prior resource use.
↵a Difference in percentage points (risk in IPC group minus risk in non-IPC group).
↵b A less urgent visit (level 4) or nonurgent visit (level 5) according to the Canadian Acuity Triage Scale.23
↵c Hospitalization for which the chief diagnosis was an ACSC: asthma, cardiac heart failure, COPD, diabetes, hypertension, angina, or seizures.24
