Clinical Trial Summary
The main objective of this study is to develop a machine learning model that predicts
postoperative respiratory failure within 7 postoperative day using a real-world, local
preoperative and intraoperative electronic health records, not administrative codes.
Description:
Postoperative pulmonary complications are known to increase the length of hospital stay and
healthcare cost. One of the most serious form of these complications is postoperative
respiratory failure, which is also associated with morbidity and mortality. A lot of risk
stratification models have been developed for identifying patients at increased risk of
postoperative respiratory failure. However, these models were built by using a traditional
logistic regression analysis. A logistic regression analysis had disadvantages of assuming
the relationship between dependent and independent variables as linear. Recent advances in
artificial intelligence make it possible to manage and analyze big data. Prediction model
using a machine learning technique and large-scale data can improve the accuracy of
prediction performance than those of previous models using traditional statistics.
Furthermore, a machine learning technique may be a useful adjuvant tool in making clinical
decisions or real-time prediction if it is integrated into the healthcare system. However, to
our knowledge, there was no study investigating the predictive factors of postoperative
respiratory failure using a machine-learning approach. Therefore, the main objective of this
study is to develop a machine learning model that predicts postoperative respiratory failure
within 7 postoperative day using a real-world, local preoperative and intraoperative
electronic health records, not administrative codes and evaluate its performance
prospectively.
