Researchers linked to the field of Healthcare within Santa Anna have conducted a series of studies over the past fifteen years in cooperation with Linköping University, Region Östergötland and companies. An area of special concern is monitoring and follow-up at home of elderly chronically ill patients with the aim of individualizing care efforts and avoiding emergency admissions. The studies involve searching for characteristic patterns indicating health deterioration based on daily reporting of symptom and status, for instance in cases of COPD and heart failure. The scientific focus is on AI techniques and human-system cooperation.
