Trial Outcomes & Findings for Balancing Treatment Outcomes and Medication Burden Among Patients With Symptomatic Diabetic Peripheral Neuropathy (NCT NCT02056431)

NCT ID: NCT02056431

Last Updated: 2018-06-28

Results Overview

The primary outcome measure is change in quality of life from baseline at eight months following study entry. We calculated the EuroQOL (EQ-5D) from the Global Health Scale, a 10-item Patient-Reported Outcomes Measurement Information System measure developed and validated in patients with neuropathy as part of the Quality of Life in Neurological Disorders Measures. The range for EQ-5D is 0-1, with "0" being the worst and "1" being the best.

IVR Intervention Group
Participants will receive 3 interactive voice response (IVR) calls (2nd, 4th, and 6th month post-treatment start date) to collect information on medication use, side effects, rating of side effects, and pain symptoms to be fed back to their physicians.
IVR Control Group
Participants will receive 3 non-interactive voice response (IVR) calls (2nd, 4th, and 6th month post-treatment start date) containing general messages regarding diabetic education.

20/604 • Number of events 20 • Adverse event data were collected for each participant from the time of enrollment through 8 months.
Given that this is a low risk study, we do not anticipate that any of the adverse events are associated with the intervention itself. We created an algorithm to extract information on deaths among participants from the electronic medical record every 6 months and reported these to the independent safety monitor.
