Formal Methods, Artificial Intelligence, Big-Data Analytics, and Knowledge Engineering in Medical Care to Reduce Disease Burden and Health Disparities

To test clinical pathways in a variety of Italian health care organizations in 2000-2002 to measure performance in decreasing process and outcome variations. Creation of indicators, specific for each clinical pathway, to measure variations in the care processes and outcomes. Pre- and post-analysis model to evaluate the possible effect of the clinical pathways on each indicator. We tested the clinical pathways in six sites, each with different clinical pathways. Reductions in health care macro-variation phenomena (length of stay, patient pathways, etc.) and in performance micro-variation (variations in diagnostic and therapeutic prescriptions, protocol implementation, etc.) were shown in sites where pathways were implemented successfully. A significant improvement in outcome for patients who were treated according to the clinical pathway for heart failure was also demonstrated. The overall purpose of clinical pathways is to improve outcome by providing a mechanism to coordinate care and to reduce fragmentation, and ultimately cost. Our results demonstrated that it is possible to achieve this goal. Although controversial elements still exist, we think that clinical pathways can have a positive impact on quality in health care.

Surveys of patients' experiences with health care services can reveal how well a country's health system is meeting the needs of its population. Using data from a 2016 survey conducted in eleven countries-Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, the United Kingdom, and the United States-we found that US adults reported poor health and well-being and were the most likely to experience material hardship. The United States trailed other countries in making health care affordable and ranked poorly on providing timely access to medical care (except specialist care). In all countries, shortfalls in patient engagement and chronic care management were reported, and at least one in five adults experienced a care coordination problem. Problems were often particularly acute for low-income adults. Overall, the Netherlands performed at the top of the eleven-country range on most measures of access, engagement, and coordination.

The French word "trier", the origin of the word "triage", was originally applied to a process of sorting, probably around 1792, by Baron Dominique Jean Larrey, Surgeon in Chief to Napoleon's Imperial Guard. Larrey was credited with designing a flying ambulance: the Ambulance Volante. Baron Francois Percy also contributed to the organisation of a care system for the ongoing management of casualties. Out of the French Service de Santé, not only emerged the concept of triage, but the organisational structure necessary to handle the growing number of casualties in modern warfare.
