Publication number: 20230048995Abstract: Systems and methods are disclosed for analyzing data from oncology treatments such as immune checkpoint inhibitor or radiotherapy therapies, including predicting adverse events of the oncology therapies, predicting objective response of the oncology therapies, predicting symptoms from the oncology therapies, and use of such predictions by technological implementations to achieve improved system and medical outcomes. An example technique for generating a predicted treatment outcome includes: receiving patient data for a human subject, which provides patient-reported outcomes collected from the human subject relating to a particular oncology treatment; processing the patient data with a trained artificial intelligence (AI) prediction model, which receives the patient data as input and produces a prediction of a treatment outcome as output; and outputting data to modify a treatment workflow of an oncology treatment for the human subject, based on the prediction of the treatment outcome.Type: ApplicationFiled: August 12, 2022Publication date: February 16, 2023Inventors: Jussi Ekström, Henri Virtanen, Santeri Mentu

Publication number: 20190362819Abstract: Studies have consistently shown that the better patients are monitored the higher the recovery and survival rates. Due to legal & technical constraints, high quality monitoring of patients has been limited to hospitals and other care facilities. However, with the aide of the systems disclosed herein, high quality patient monitoring can be extended outside of these care facilities and thereby further increase recovery and survival rates in patients not confined to healthcare facilities. This is particularly relevant in the monitoring and treatment of chronic illnesses, for example with cancer treatment.Type: ApplicationFiled: May 28, 2018Publication date: November 28, 2019Applicant: Kaiku Health OyInventors: Henri VIRTANEN, Ramin BAGHAIE, Lauri SIPPOLA
