Strategic Use of Big Data in Spine Surgery - Testing Digital Prediction of Outcome in Clinical Praxis

The goal of this prospective, multicenter clinical trial is to determine if the use of the postoperative outcome prediction model the Dialogue Support tool can alter postoperative patient-reported outcome and satisfaction compared to current practice. The main questions it aims to answer are: * Does its use alter patient-reported outcome measured by general assessment regarding leg pain and Satisfaction in lumbar spinal stenosis? * Does its use alter patient-reported outcome as measured by general assessment regarding arm pain and Satisfaction in cervical rhizopathy? * How does the Quality of Life in patients - who after assessment by spinal surgeon do not proceed to surgery - compare with patients with the same baseline profile who did undergo surgery? Eligible participants will be presented with their predicted postoperative outcome generated by the Dialogue Support tool, as an adjunct to the ordinary assessment by a spine surgeon. Researchers will compare participants with a matched control group from the Swedish Spine Register ("Swespine") to see if the Dialogue Support tool can alter postoperative patient-reported outcome and satisfaction.

Comparison of the Diagnostic Performance and Costs of FFRB Vs. Standard Care in Suspected Coronary Artery Disease.

Chest pain due to coronary artery disease (CAD) is a main driver of healthcare costs. Fractional flow reserve (FFR) measurement during invasive coronary angiography (ICA) is the gold standard to discriminate ischemia. A rapid simplified method had been developed to determine non-invasive FFR (FFRB) by applying computational fluid dynamics (CFD) simulation on anatomic models derived from computed tomographic coronary angiography (CTCA).In this current study, the aims is to compare the diagnostic accuracy, clinical effectiveness, safety outcomes, and quality of life of using FFRB on top of CTCA for CAD diagnosis and treatment planning, versus standard of care in Singapore; and measure health care resource utilization and assess cost-effectiveness of adopting FFRB on top of CTCA to support decision making in managing patients with suspected CAD.
