Table 5 Variables independently associated with 156 unplanned recurrent ED visits for hyperglycemia within 30 days as determined by multivariable logistic regression model and generalized estimating equations

From: Risk factors for recurrent emergency department visits for hyperglycemia in patients with diabetes mellitus

Risk Factor Beta Co-efficient Standard Error P value Adjusted Odds Ratio 95% Confidence Interval
 Previous hyperglycemia visit in past month 1.26 0.26 <0.01 3.5 2.1, 5.8
 Age < 25 years 0.97 0.30 <0.01 2.6 1.5, 4.7
 Glucose > 20 mmol/L 0.80 0.26 <0.01 2.2 1.3, 3.7
 Have a family physician 0.77 0.39 0.04 2.2 1.0*, 4.6
 On insulin 0.62 0.26 0.02 1.9 1.1, 3.1
Protective Factor
 Systolic blood pressure 90-150 mm Hg 0.63 0.29 0.03 0.53 0.30, 0.93
 Heart rate > 110 bpm 0.90 0.29 <0.01 0.41 0.23, 0.72
  1. Where SE standard error, bpm beats per minute
  2. Note: No test for goodness-of-fit available under generalized estimating equation modeling
  3. *The lower limit of the 95% confidence interval for having a family physician was 1.01
