Table 7.

Unadjusted Comparison of Average Length of Stay Rates for Remaining Control and Test Group Participants, after Removal of All Outlier Admissions (LOS, ≥33 days)

Period	Test group	Control group
Time of first emergency department visit	81 admissions; 4.65 days	107 admissions; 4.75 days
Time of second emergency department visit	152 admissions; 4.66 days	110 admissions; 5.73 days

Decrease in ALOS for the test group between emergency department visits = 4.65 × (5.73/4.75) − 4.66 = 0.95 days per admission.

ALOS indicates average length of stay; LOS, length of stay.
