Age: greater than 54 (n=42) compared with less than 35 y (n=107)	1.41 (1.02 to 1.94)	1.08 (0.57 to 2.03)
Gender: female (n=108) compared with male (n=142)	0.90 (0.69 to 1.18)	0.91 (0.60 to 1.38)
Race/ethnicity: nonwhite (n=125) compared with white (n=123)	0.87 (0.67 to 1.14)	0.99 (0.65 to 1.52)
Education level: less than college degree (n=130) compared with college degree or greater (n=112)	0.83 (0.63 to 1.09)	0.99 (0.64 to 1.51)
Distance from clinic: 7 or more miles (n=108) compared with 7 or more miles (n=142)	0.87 (0.66 to 1.14)	0.87 (0.58 to 1.30)
PCP: having a PCP (n=143) compared with not having a PCP (n=107)	1.52 (1.13 to 2.03)	1.52 (0.95 to 2.43)
Disease category: injury (n=85) compared with noninjury (n=165)	1.07 (0.82 to 1.41)	0.99 (0.65 to 1.50)
Insurance status: HMO (n=43) compared with standard (n=118)	1.01 (0.71 to 1.42)	0.94 (0.55 to 1.58)
Insurance status: no insurance (n=39) compared with standard (n=118)	0.76 (0.51 to 1.13)	0.78 (0.45 to 1.37)
Insurance status: Medicare (n=21) compared with standard (n=118)	1.22 (0.83 to 1.78)	0.99 (0.47 to 2.09)
Insurance status: Medicaid (n=16) compared with standard (n=118)	0.37 (0.13 to 1.04)	0.25 (0.06 to 1.04)
Discharge instruction: intervention (n=119) compared with standard (n=131)*	1.61 (1.22 to 2.10)	1.84 (1.24 to 2.13)

^*Subjects in the intervention group had an outpatient appointment with their PCP or referral physician made before discharge. Subjects in the standard group were asked to follow-up with their PCP or with the referral physician recommended to them.
