Outcome

Type
SECONDARY
Title
Pain Interference Score ≥ 4 at 2 Weeks Post Discharge
Description
Pain interference scores ≥ 4 on the Brief Pain Inventory (numeric scale from 0 to 10) at 2 weeks post-discharge. The BPI measures pain severity on a numeric scale of 0 to 10, with 0 being no pain and 10 being the highest level of pain. This outcome asks participants to indicate their pain scores for the week prior to completing the inventory.
Time frame
2 weeks post discharge
Population
Data were missing for 234 participants in the IOPP group and for 286 in the fixed group
