Table 4 Predictors of the proportion of admissions that were emergency (linear regression, n = 221)

From: Exploration of population and practice characteristics explaining differences between practices in the proportion of hospital admissions that are emergencies

Variable Beta SE Beta Sig Adjusted R Sq
Constant 0.026 0.075   
Deprivation index 0.004 0.000 <0.001 0.473
Proportion of patients who were male 0.720 0.116 <0.001 0.572
Outpatient appointments per 10,000 patients 0.002 0.000 <0.001 0.590
Proportion of white patients −0.001 0.000 <0.001 0.616
Recorded hypertension prevalence −0.461 0.129 <0.001 0.629
Practice list size/100 −0.002 0.001 0.001 0.644
Proportion aged 65 or over 0.063 0.458 0.648  
Proportion of total clinical QOF points obtained −0.053 −1.148 0.253  
Proportion of patients able to consult their preferred GP −0.039 −0.845 0.399  
  1. Beta indicates the amount of change for one unit change of the independent variable, controlling for the other independent variables. Thus, an increase of 1% in the proportion of the practice population who are male is associated with a 0.7% increase in the proportion of admissions that are emergency, whilst a 1% increase in recorded prevalence of hypertension is associated with a 0.46% decrease in the proportion of admissions that are emergency.
