High economic efficiency in addition to high quality cares is important to provide safe and reliable medical services. However, the quality and economics of medical services are in a trade-off relationship. In other words, higher quality of medical treatments causes lower economic efficiency due to increase in costs, and higher economic efficiency leads to lower quality of medical treatments due to reduction in costs.
To solve the difficult problem of achieving both quality of medical care and economic efficiency, Intelligent Systems Laboratory is engaged in research to quantitatively grasp treatment results and apply it to hospital management.
Post-operative infection (POI) is one of the events that we focused on to evaluate both the quality and economics of medical treatment. After invasive surgery, infections may develop due to a decrease in the strength of the patient. POI is a serious burden on the patient, but also on hospital because of opportunity losses of treating other patients.
By visualizing POI cases, potential losses were revealed allowing corrective measures to be implemented. The quality and economics of medical treatment were evaluated by using hospital quality indicators obtained from the hospital information system. In addition, regular feedback of the hospital quality indicators led the improvements.
