Aims

The aim of this study was to identify factors associated with five-year cancer-related mortality in patients with limb and trunk soft-tissue sarcoma (STS) and develop and validate machine learning algorithms in order to predict five-year cancer-related mortality in these patients.

Methods

Demographic, clinicopathological, and treatment variables of limb and trunk STS patients in the Surveillance, Epidemiology, and End Results Program (SEER) database from 2004 to 2017 were analyzed. Multivariable logistic regression was used to determine factors significantly associated with five-year cancer-related mortality. Various machine learning models were developed and compared using area under the curve (AUC), calibration, and decision curve analysis. The model that performed best on the SEER testing data was further assessed to determine the variables most important in its predictive capacity. This model was externally validated using our institutional dataset.

Increased emphasis has been placed on hospital length of stay and discharge planning after total joint arthroplasty. The purpose of this study was to identify patient characteristics and assistance of surgical innovation could reduce length of stay of an inpatient after TJA.

Method: We analysed demographic and Clinical data 92 consecutive patients who underwent primary TKR with computer assisted surgery [n=46] and compare with another group operated with manual technique[n=46].

Result: Average length of stay: 8.87days (+/− 5.16 SD) in the navigation group and 7.59days (+/− 3.82 SD) in the manual group. Older age, higher American Society of Anesthesiologists class, social circumstances, and female sex were all associated with a higher likelihood of discharge to an ECF.

Conclusion: No Significant differences in length of stay patterns were found in this cohort with respect to discharge disposition at home after knee joint replacement. We believe to reduce length of stay while maintaining quality of care, early discharge home with integrated community services or home care nursing and physiotherapy should be more important than surgical innovation in the NHS in U.K
