The concept of value-based health care defines value as the outcomes achieved in treating a patient for a medical condition, relative to the costs incurred during a complete care cycle. A radar chart enables clinicians to display outcomes and cost data simultaneously.
This radar chart, using data from MD Anderson Cancer Center, compares the value of three alternative treatments for low-risk prostate cancer: brachytherapy, robotic prostatectomy, and proton therapy. The outcomes data for each treatment (from ICHOM-recommended metrics) are graphed on separate axes, scaled from 0 to 100. Cost is plotted as the reciprocal of actual costs (according to time-driven activity-based costing), so that points farther from the center always represent better value.
A radar chart depicting outcomes and costs offers clinicians, managers, patients, regulators, and policy makers an easily understood snapshot of value, comparing therapies, facilities, and clinicians that treat the same medical condition. This visual rendering helps providers identify and communicate best practices for delivering better outcomes at lower costs.
