Systematic review of techniques to monitor remission of acute Charcot-neuroarthropathy in people with diabetes.

AIM: The management of acute Charcot-neuroarthropathy relies on offloading which is costly and time consuming. Published studies have used monitoring techniques with unknown diagnostic precision to detect remission. We performed a systematic review of techniques for monitoring response to offloading in acute Charcot neuroarthropathy. MATERIALS AND METHOD: We included studies of off-loading which evaluated or described monitoring techniques in acute Charcot neuroarthropathy. PubMed, EMBASE, CINAHL and Cochrane databases were searched (January 1993-July 2018). We extracted data from papers including study design, setting, population, monitoring techniques and treatment outcomes. We also extracted information on the cost, clinical applicability, sensitivity and specificity, safety and participant acceptability of the monitoring techniques. RESULTS: We screened 1205 titles, 140 abstracts and 45 full-texts, and included 29 studies. All studies were of low quality and at high risk of bias. In seven studies the primary aim was to evaluate monitoring techniques: three evaluated MRI, two thermography monitoring, one three-phase bone scanning and one Doppler spectrum analysis. The remaining 22 observational studies reported treatment outcomes and reported the monitoring techniques used to assess the CN. Heterogeneity prevented the pooling of data. Very few studies included data were found on cost, clinical applicability, sensitivity and specificity, safety and patient acceptability of the monitoring techniques used. CONCLUSION: Multiple techniques have been used to evaluate remission in acute CN but uncertainty remains about their effectiveness. We recommend further research into the influences of different monitoring techniques on treatment outcomes. This article is protected by copyright. All rights reserved.
