Multiple regression results for model relating UHC MRSA hospitalization rates per 1,000 hospitalizations to Google searches for “MRSA” or “staph” (normalized and scaled)*

Characteristic Coefficient 95% CI SE t value p>t
Intercept 9.03 7.56 to 10.50 0.69 13.07 <0.001
Google searches 0.25 0.18 to 0.32 0.032 7.73 <0.001
2007 4th quarter indicator −21.45 −28.10 to −14.80 3.12 −6.87 0.001
2008 indicator −3.06 −4.55 to −1.57 0.70 −4.37 <0.001

*UHC, University HealthSystems Consortium; MRSA, methicillin-resistant Staphylococcus aureus; CI, confidence interval. The overall model F(3,15) was 29.69 (p<0.0001), R2 0.8559, and adjusted R2 0.8270. Correlation coefficient between predicted values of this model and observed rates was 0.9251.
