Abstract
IntroductionDiabetic peripheral neuropathic pain (DPNP), a symptom of diabetic polyneuropathy (DPN), is underdiagnosed in people with diabetes. To date, no studies have determined the relationship between diagnosis of DPN and satisfaction with treatment for pain. Additionally, the factors that influence satisfaction with treatment for pain remain unknown. This questionnaire study was conducted to understand satisfaction with treatment for pain among participants with diabetes who experienced bilateral pain or numbness in their feet.MethodsThis cross-sectional, observational, web-based questionnaire study for participants with diabetes and suspected DPNP was conducted in Japan. Potential respondents were registered in the INTAGE Disease Panel or the Rakuten Insight Disease Panel. The primary endpoint was the number and percentage of participants who were satisfied with their DPNP treatment. Secondary endpoints included participant opinions regarding treatment-related efficacy, side effects, and economic burden, and factors affecting satisfaction with treatment.ResultsThe questionnaire was accessed by 7565 potential participants; 777 met the eligibility criteria (final analysis set). Satisfaction with treatment for bilateral foot pain was low (satisfied, 27.9%; neither satisfied nor unsatisfied, 42.2%; unsatisfied, 23.4%; very unsatisfied, 6.4%). Participants were somewhat more satisfied with treatment side effects than with treatment efficacy and economic burden. Satisfaction with treatment mainly differed by improvement in actions in daily life, improvement in quality of life, and communication with doctors. The diagnostic testing rate for DPN was low, and diagnosis was more common in participants who complained of symptoms of pain and numbness (any visit) versus those who did not.ConclusionParticipants with diabetes who experience bilateral foot pain or numbness reported a low level of satisfaction with treatment for pain.Supplementary InformationThe online version contains supplementary material available at 10.1007/s12325-021-01810-x.
