Demographic Model - Emergency hospital admissions in terms of practice-level demographic data, derived using the BIC criterion
Variable Incidence Rate Ratio (IRR) 95% CI P value (2-sided)
Distance (per km) 0.9874 0.9762 to 0.9987 0.028
IMD (per unit) 1.0014 0.9971 to 1.0057 0.519
Interaction term:
Distance (per km) × IMD (per unit) 1.0009 1.0004 to 1.0014 0.001
Age65≥ years (per 1%) 1.0224 1.0095 to 1.0355 0.001
Males (per 1%) 1.1535 1.0899 to 1.2209 <0.001
White population (per 1%) 1.0990 1.0520 to 1.1481 <0.001
Interaction term:
Males (per 1%) × White pop (per 1%) 0.9981 0.9973 to 0.9989 <0.001

BIC (Bayesian information criterion) = 1865.306.

IRR less than 1.0 represent decreases and IRR greater than 1.0 represent increases in the count.
