Abstract
Treatment of patients with rotator cuff tears usually starts with physical therapy, but some patients will still eventually need surgery. Ineffective physical therapy increases the time and cost of treatment and pain for patients. The quality of treatment can be improved if patients who will not respond to physical therapy are identified at an early stage. However, there is little research available to systematically help physicians make a timely decision on whether a surgical treatment is eventually needed or not. In this research, we developed a decision support system that can predict the probability of eventually needing a surgical treatment by effectively analyzing the available patients’ information at an early stage. Missing value imputation, variable selection, and classification methods are integrated in developing such a decision support system. The probability given by our model will either confirm physician's expert decision, or remind physician if there is any information ignored. This research has the potential to improve patient safety, reduce cost of unnecessary treatment, and help physicians prevent treatment errors.
