Ability of the canine brief pain inventory to detect response to treatment in dogs with osteoarthritis.

Abstract

OBJECTIVE: To determine whether the Canine Brief Pain Inventory (CBPI) can detect changes in dogs with osteoarthritis treated with an NSAID or a placebo. DESIGN: Double-blind, randomized, placebo-controlled clinical trial. ANIMALS: 70 dogs with osteoarthritis. PROCEDURES: Owners completed the CBPI on day 0. Dogs received carprofen or a placebo on days 1 through 14. Owners completed the CBPI again on day 14. Pain severity and pain interference scores from the CBPI were calculated, and the change from day 0 to day 14 was assessed within each group and between groups. RESULTS: No significant differences were detected in median scores for pain severity (3.50 and 3.25 on days 0 and 14, respective..
