Background: Screening for diabetic peripheral neuropathy (DPN) is easily omitted in the busy clinical setting. SUDOSCAN is a non-invasive and convenient tool for evaluating small-fiber neuropathy, but its clinical effectiveness for screening of DPN is lacking. We investigated whether SUDOSCAN combined with a neuropathy questionnaire could be an effective tool for screening for DPN in people with type 2 diabetes. Methods: We analysed the data for 197 people with type 2 diabetes without renal dysfunction or changes in their use of anti-hyperglycaemic medications during the past 3 months. The presence of DPN was evaluated using the Michigan Neuropathy Screening Instrument Physical Examination (MNSI-PE). Electrochemical skin conductance (ESC) of the feet was assessed using SUDOSCAN, and the MNSI Questionnaire (MNSI-Q) and 10-gram monofilament tests were conducted. We developed a scoring model including various combinations of clinical parameters and neuropathy examination results. Results: The prevalence of DPN was 42.6%. Participants with DPN were older (59.9 ± 9.5 vs. 56.7 ± 8.8 years) and had a longer duration of diabetes than those without DPN. Feet ESC distinguished the presence of DPN, and the optimal cut-off value was 69.5 uS. The OR for the association between an abnormal feet ESC ( Conclusions: The screening model for DPN that includes SUDOSCAN and the MNSI-Q can detect DPN with acceptable discrimination power and is more convenient than neurophysiological studies. This strategy may be useful in the busy outpatient clinical setting. Disclosure T. Oh: None. K. Kim: None. Y. Shin: None. H.
