"Many Americans assume that the health care they receive is based on strong medical evidence of intervention and treatment effectiveness. However, as suggested by regional analyses, recommended care is often not delivered and insufficient evidence often leads to wide practice variations with little to no health benefit to patients (Fisher et al., 2003b; McGlynn et al., 2003). In addition to negatively impacting health outcomes, practice inconsistencies have dramatic effects on the overall costs of health care—costs which represent the most pressing fiscal challenge to the nation."

"AI systems can utilise such clinical data to enhance diagnostic accuracy and enable clinicians to offer patient-centred medical care, while eliminating variations across the country and helping patients in managing their conditions themselves."
