Détection automatique des infections du site opératoire

Abstract : Introduction Improving monitoring and prevention of surgical site infections (SSI) is part of the national nosocomial infection control program. Our goal was to implement an automated detection tool with a supervised machine learning to replace the current manual system. Method Two approaches were conducted to detect SSI following spine surgery and neurosurgery corresponding to 2133 and 2303 procedures respectively. The first approach uses the multiple sources of information available in the data warehouse of Bordeaux University Hospital. The second approach uses only free text. For each approach, we compared the precision of two algorithms namely logistic regression and random forests algorithms for a fixed recall value of 100%. Results The final model using all the data achieved the best performance for spine surgery with a precision of 94%. The model using free text data obtained correct results and was better for neurosurgery. Discussion The use of free text has the advantage of being replicable to other health institutions and applicable to various surgical specialties with stable performance. The performance of our algorithms needs to be evaluated on a test dataset.
