Question on the use of PDA in a typical day at the six month administration	Correlations ∗ between H-DSS Score at Two Different Times † and PDA Usage at Six Months‡
	Baseline H-DSS score	Score after 6 months of use
How often do you use your handheld computer for any purpose, outside the medical setting?	0.18 (p = 0.133)	0.36 (p = 0.002)
How often do you use your handheld computer to access medical information in regard to your hospitalized patients?	0.46 (p < 0.001)	0.55 (p < 0.001)
How often do you use your handheld computer to access medical information in regard to the patients seen in your office?	0.26 (p = 0.037)	0.48 (p < 0.001)
