Nerve conduction studies (NCS) and electromyography (EMG) are being inappropriately over indicated, reducing the performance of the test to confirm any neuromuscular pathology. Objectives: To assess the relevance of the indication and clinical utility of NCS and EMG, and to identify potential groups of patients in whom it is particularly useful. Methods: This is an observational study, derived from a series of cases of 318 adult patients who were analyzed retrospectively, underwent for the first time to NCS and/or EMG during January-October 2019 in a Peruvian hospital. Results: We recorded 28% of normal results. In 78.6% of the cases the indication was appropriate, mainly by specialists (91.6% vs 51.5%; p=0.000). Concordant diagnosis was obtained in 60.7%. In 72.3% of the cases, the result of the examination implied some change in management. In the logistic regression model: motor deficit, the presence of signs of neural tension and the consignment of a specific pre-test reference diagnosis were strongly related to a more appropriate indication and abnormal test results. Conclusions: Our study confirms the adequate relevance of the indication of NCS and EMG by specialists, in contrast with primary care physicians, and they are potentially useful in an appropriate clinical context.
