Abstract

Objective: To determine patient preferences regarding the duration of trial period.
Materials and Methods: Forty patients were given a trial of spinal cord stimulation. They were questioned daily if they would liketo proceed to a permanent implant. Three consecutive affirmative answers implied a successful trial; three negative replies implied a failed trial. Patients rated daily the pain from the surgery, original pain, satisfaction with the stimulator, and the duration of theuse of the stimulator.
Results: The trial duration varied from 3 to 15 days. Patients with a failed trial took longer to make a decision and also experienced prolonged surgical pain. The majority of patients with a successful trial experienced more than 50% pain reduction. The rate of infection was 7.5%, which has reduced to 2.8% after changing the dressing protocol.
Conclusions: In this study, all patients could make a decision in 15 days, with successful trials requiring a shorter duration. The conversion rate was similar to rates in literature despite patients making a decision without physician input.
