Artificial Intelligence (AI) has transformed almost every field today and has the potential to improve existing systems through automation, predictions, and optimizing decision-making. Breast reconstruction is a very common surgical procedure, with Implant-based reconstruction (IBR) being used in most cases. However, this process is often accompanied by periprosthetic infection, which causes significant distress to patients and leads to increased healthcare costs. This research from the University of Texas explores how Artificial Intelligence, particularly Machine Learning (ML) and its capabilities, could be leveraged to predict the complications of IBR, ultimately improving the quality of life.
The risks and complications associated with breast reconstruction depend on numerous non-linear factors, which the conventional methods are unable to capture. Therefore, the authors of this paper have developed and evaluated nine different ML algorithms to better predict the IBR complications and have also compared their performance with traditional models.
The dataset consists of patient data collected over the course of around two years, gathered from The University of Texas MD Anderson Cancer Center. Some of the different models used by the researchers include an artificial neural network, support vector machine, random forest, etc. Additionally, the researchers also used a voting ensemble using majority voting to make the final predictions to get better results. For performance metrics, the researchers used the area under curve (AUC) to choose the optimal model after three rounds of 10-fold cross-validation.
Among the nine algorithms, the accuracy of predicting Periprosthetic Infection ranged from 67% to 83%; the random forest algorithm demonstrated the best accuracy, and the voting ensemble had the best overall performance (AUC 0.73). Regarding predicting explanation, accuracies ranged from 64% to 84%, with the Extreme gradient boosting algorithm having the best overall performance (AUC 0.78).
Additional analysis also identified important predictors of periprosthetic infection and explanation, which provides a more robust understanding of the factors leading to IBR complications. Factors such as high BMI, older age, etc, lead to a higher risk of infections. The researchers observed that there is a linear relationship between BMI and infection risk, and even though other studies reported that age does not influence IBR infections, the authors identified a linear relationship between the two.
The authors have also highlighted some of the limitations of their models. Since the data is gathered from only one institute, their results are not generalizable to other institutes. Moreover, additional validation would enable the clinical implementation of these models and help reduce the risk of devastating complications. Additionally, clinically relevant variables and demographic factors could be integrated into them to further improve their performance and accuracy.
In conclusion, the authors of this research paper have trained nine different ML algorithms to predict the occurrence of IBR complications accurately. They also analyzed various factors that influence IBR infections, some of which were neglected by previous models. However, some limitations are associated with the algorithms, such as data being from just one institute, lack of additional validation, etc. Training the model with more data from different institutes and adding other factors (clinical as well as demographic) will improve the model’s performance and help medical professionals tackle the issue of IBR infections better.
