Univariate (unadjusted) and multivariate (adjusted) models describing the association between primary care service utilisation, defined as number of contacts with primary care services, cardiovascular disease and mortality, in the CHIA data set between 2013 and 2020
| Unadjusted OR (95% CI) per additional primary care contact | Univariate p value | Adjusted* OR (95% CI) per additional primary care contact | Multivariate p value | |
| Cardiovascular disease† | 1.0071 (1.0066 to 1.0074) | <0.001 | 1.0057 (1.0052 to 1.0061) | <0.001 |
| Mortality | 1.0077 (1.0070 to 1.0082) | <0.001 | 1.0056 (1.0050 to 1.0063) | <0.001 |
*Adjusted for age, sex, ethnicity, index of multiple deprivation, smoking status, number of prescribed medications, frailty, BMI, HbA1c, systolic and diastolic blood pressure, mean total cholesterol and practice-level comorbidity prevalence to account for local clustering.
†Defined as a composite of myocardial infarction, amputation and stroke.
