Comparison of Average Length of Stay for Propensity-Matched Control and for Test Groups
| Period | Test group, average stay | Control group, average stay |
|---|---|---|
| Time of first emergency department visit | 5.13 days | 5.65 days |
| Time of second emergency department visit | 6.14 days | 11.47 days |
Decrease in ALOS for the test group between emergency department visits = 5.13 × (11.47/5.65) − 6.14 = 4.27 days/admission.
ALOS indicates average length of stay.
