Lille researchers announced on Tuesday that they had put online a tool capable of predicting weight loss over five years for people suffering from obesity, in order to inform their choice before considering bariatric surgery, and to improve their medical monitoring. .
Weight, height, age, smoker/non-smoker, type of diabetes and type of intervention, immediate benefit of weight loss and stabilization phase: this tool presented by the Lille University Hospital with researchers from the University of Lille, Inria (National Institute for Research in Digital Sciences and Technologies), Inserm (National Institute of Health and Medical Research) questions “seven predictive attributes” which draw on screen the curve of a patient according to the planned surgery.
An algorithm validated on 10,000 patients and accessible online
Engineers from Inserm and a mathematician used data from 1,500 patients operated on and followed at the Lille University Hospital since 2006 to develop this “decision support tool” based on an algorithm as part of a European project (IMI Sophia), initiated three years ago.
The performance of the model was then validated in more than 10,000 patients followed in Europe and abroad (Netherlands, Finland, Sweden, Switzerland, Singapore, Mexico, Brazil), as part of the European Sophia project. The results obtained in this study confirm and validate the scientific excellence of the project.
The tool is accessible at https://bariatric-weight-trajectory-prediction.univ-lille.fr and the results of this study were published in the British scientific journal The Lancet Digital Health on August 29.
“We wanted a communication tool“, indicated Professor François Pattou, director of the Inserm unit “translational diabetes research” during a press conference.
NO to diets, YES to WW!
Decision support for the doctor and the patient
“We have people who ask us: +And if I have surgery, what will it do?+. Before, doctors said +you are going to lose 30% of your weight (…) In the doctor’s mind that means something, but it is not transmissible“, indicated this doctor who co-directed the project with Philippe Preux, head of the Inria project team.
“If losing weight is interesting, that means it’s interesting to go for it“, testified Guillaume Veret, a patient who went from 135 to 88 kg after a stomach reduction operation at age 36 7 years ago. “The operation is not a miracle solution, behind it there is a lot of work that must be done over the long term: vitamin supplementation and lifelong physical activity, diet, rhythms, etc.“, he recalled.
