Balancing Treatment Outcomes and Medication Burden Among Patients With Symptomatic Diabetic Peripheral Neuropathy
Painful diabetic peripheral neuropathy (DPN) affects more than 5.5 million people with diabetes. People with painful DPN have trouble sleeping, participating in social events, and conducting daily activities such as going to the store. Several prescription medications are available for the treatment of DPN symptoms, but none work perfectly and all have side effects that may be difficult for some patients.
When patients report their symptoms and side effects to their doctor, they provide the doctor with important information to help them make adjustments to treatment that will help with symptoms and that the patient can tolerate in terms of side effects. In some cases, doctors may encourage patients to make these changes on their own at home based on their experience with therapy. However, patients may have a long time between visits to their doctor and may have trouble describing their symptoms to their doctor during a brief 10 to 15 minute visit.
This clinical trial explores the possibility of computerized telephone calls to patients (Interactive Voice Response, IVR, technology) to gather information about treatment experiences that can then be reported to the doctor or used to guide patients to make changes in how they take the medication. It addresses the following question: Can routinely asking patients about their experiences with medications and using that information to encourage clinically appropriate titration improve patient quality of life?
The investigators hypothesize that systematic collection and feedback of information about DPN treatment preferences and experience from newly treated patients to their primary care physician will facilitate treatment changes that improve patient outcomes

Gedetailleerde beschrijving
Among newly-treated Diabetic Peripheral Neuropathy (DPN) patients, the investigators will compare the systematic collection and feedback of information about patients' treatment experiences on changes in quality of life (intervention group) to newly treated DPN patients in usual care who will receive generic educational messages by phone but no active data collection and feedback (comparator group). The investigators have chosen usual care as the control to evaluate the potential for the intervention to enhance current practice.
Aim 1: Refine and pilot test instruments for collecting the patient-reported data most important for guiding changes in treatment.
Aim 2: Implement a seven-month cluster randomized trial to improve quality of life among patients newly treated for DPN symptoms by collecting data on patient treatment experiences and facilitating evidence-based patient and provider-initiated treatment titration.
Aim 3: Examine patient and physician initiated treatment changes as secondary outcomes in order to inform the development of this type of rapid feedback process for guiding decision making about initial treatment selection among patients with DPN.

Experimenteel: 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.

Change in Patient Quality of Life at Baseline and 8 Months
Tijdsspanne: Baseline and 8 months
|
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.
